It is judged by how much good product leaves the line, how consistently, with how much rework, with what weight accuracy and with what level of traceability.

In a sentence: it is the point at which agricultural raw material must become a compliant, traceable and profitable commercial product.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The three objectives that must coexist<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A well-managed packing house must balance three objectives that are often treated separately:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Productivity<\/strong>, meaning the capacity to turn volumes into useful output without building up waiting times and micro-stops.<\/li>\n\n\n\n<li><strong>Quality standards<\/strong>, meaning consistency of size, weight, appearance, integrity and product presentation.<\/li>\n\n\n\n<li><strong>Traceability<\/strong>, meaning the ability to know at all times which batch came in, how it was processed and where it ended up.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most common mistake is optimising a single variable. If I increase speed but waste gets worse, I am not improving. If I reduce defects but slow the end of line down to the point of blocking the entire department, I am not improving. If I produce a lot but cannot reconstruct batches within a few minutes, the system remains fragile.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Where technology and design really make the difference<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the fruit and vegetable sector, the quality of the result depends heavily on how the product is handled and measured. That is why both the layout and the installed technologies matter. Bulltec, for example, presents itself as a company that develops bespoke modular systems for the processing, grading and packaging of fruit and vegetables: you can find out more on the page <a href=\"https:\/\/bulltec.it\/en\/company\/\">Company | Bulltec, tailored produce technology<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the machine side, solutions such as <a href=\"https:\/\/bulltec.it\/en\/electronic-paddle-graders\/\">electronic paddle graders<\/a> are relevant because they combine sorting, operational continuity and gentle handling. In the configurations described on the Bulltec website, size grading via machine vision can reach a precision in the order of \u00b13 mm, while sorting by weight can operate with an indicative precision of \u00b13% depending on product and configuration. Downstream, <a href=\"https:\/\/bulltec.it\/en\/combination-weighing-system\/\">combination weighing<\/a> systems and the <a href=\"https:\/\/bulltec.it\/en\/smart-combination-weigher\/\">Smart combination weigher<\/a> help to better control pack weight and reduce giveaway. Technology, however, only delivers results when it is supported by process, routines and <a href=\"https:\/\/bulltec.it\/en\/services\/\">consultancy and support services<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>End-to-end process map: from reception to shipping<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To increase productivity and control, it is not enough to look at the most expensive machine on the line. You need to map the entire flow, from product arrival to the finished pallet. In packing houses, hidden costs build up above all in the hand-offs between one stage and the next.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reception and unloading: where the first delays arise<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The process begins with unloading and batch identification. Time and control are lost here when:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>product arrives without clearly defined processing priorities;<\/li>\n\n\n\n<li>batches are not uniquely identified;<\/li>\n\n\n\n<li>there is no rule on unloading sequence and line feeding order;<\/li>\n\n\n\n<li>initial quality checks are too slow or too superficial.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If reception does not filter properly, the problem carries through everywhere: mixed batches, queues at line infeed, operator waiting times and artificial emergencies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Pre-sorting, washing and drying: losses that seem minor<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Intermediate stages are often underestimated because they are not always the main bottleneck. Yet many micro-stops originate here. Typical cases are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>manual pre-sorting not balanced against incoming volume;<\/li>\n\n\n\n<li>washing or drying with lower capacity than the next stage;<\/li>\n\n\n\n<li>waiting times between belts and tables due to a lack of smart buffers;<\/li>\n\n\n\n<li>product that is too wet or too unstable for accurate weighing downstream.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The result is an irregular flow. The grader receives peaks and gaps instead of a constant feed, and the whole line becomes harder to manage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Grading, weighing and packaging: the economic heart of the line<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the area where much of the margin is decided. Waste here is highly visible, but not always well measured. The signals to read are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>grading saturation with build-ups upstream;<\/li>\n\n\n\n<li>loss of accuracy on size or weight;<\/li>\n\n\n\n<li>frequent recipe or format changeovers without set-up standards;<\/li>\n\n\n\n<li>weight giveaway for fear of underweight;<\/li>\n\n\n\n<li>excessive manual intervention when closing packs.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When packaging runs slower than sorting, WIP builds up. When weighing is not stable, rework follows. When labelling is not aligned with the active order, non-conformities arise that can cost far more than a short stoppage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>End of line, palletising and shipping: the bottleneck many discover too late<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Investment is often made upstream while the end of line is left undersized. The result is that the line produces, but finished product does not leave continuously. The classic signs are pallets waiting, logistics labels printed late, operators manually moving packs to free up space, and loads ready to go that are not closed in the system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why <strong>Value Stream Mapping<\/strong> in the packing house must include not only process times but also waiting times, transfers, intermediate build-ups and rework. If you want to go into methodological detail on WIP, layout and constraints, the next step is <a href=\"https:\/\/bulltec.it\/en\/?p=4705\">Optimising flows and layout of the fruit and vegetable line<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Essential KPIs for managing the line in the fruit and vegetable packing house<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The useful KPIs are few, but they must be measured well and at a consistent frequency. A good control system avoids two extremes: having only after-the-fact financial figures, or having dozens of indicators that nobody uses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The KPIs that really matter<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><strong>KPI<\/strong><\/th><th><strong>What it measures<\/strong><\/th><th><strong>Why it matters<\/strong>&nbsp;<\/th><\/tr><\/thead><tbody><tr><td>Throughput<\/td><td>cases\/hour, kg\/hour or pieces\/hour per stage<\/td><td>Shows where the line is losing real capacity<\/td><\/tr><tr><td>OEE<\/td><td>availability \u00d7 performance \u00d7 quality<\/td><td>Shows why theoretical capacity does not become useful output<\/td><\/tr><tr><td>Waste<\/td><td>share of unsaleable product<\/td><td>Measures direct losses in yield and margin<\/td><\/tr><tr><td>Rework<\/td><td>packs or product reworked<\/td><td>Signals process instability<\/td><\/tr><tr><td>Lead time<\/td><td>time from reception to pallet ready<\/td><td>Measures overall flow smoothness<\/td><\/tr><tr><td>Weight giveaway<\/td><td>grams over target per pack<\/td><td>Affects margin silently but continuously<\/td><\/tr><tr><td>Label accuracy<\/td><td>label errors or mismatches per batch<\/td><td>Protects compliance and traceability<\/td><\/tr><tr><td>Yield<\/td><td>saleable output over processed input<\/td><td>Links productivity and quality<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How to read OEE without misusing it<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">OEE is only useful if it does not become a cosmetic figure. In a fruit and vegetable packing house:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Availability<\/strong> tells you what share of planned time the line was actually available.<\/li>\n\n\n\n<li><strong>Performance<\/strong> compares theoretical speed with actual speed.<\/li>\n\n\n\n<li><strong>Quality<\/strong> measures the share of right-first-time compliant output.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a line has good performance but low quality, the problem is not speed: it is the process. If quality is high but availability is low, the issue lies in stoppages, set-ups or maintenance. If everything looks good but throughput remains low, you are probably measuring at the wrong point or not taking the real constraint into account.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Where to measure and how often<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The minimum measuring points should be:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>batch intake and quantity received;<\/li>\n\n\n\n<li>pre-sorting output;<\/li>\n\n\n\n<li>grading output;<\/li>\n\n\n\n<li>weighing or combination weighing station;<\/li>\n\n\n\n<li>compliant packs at the end of line;<\/li>\n\n\n\n<li>pallets ready for shipping.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ideal frequency is not the same for everything. Throughput and stoppages require near real-time visibility; waste and rework should be read by time slot and shift; weight giveaway and label errors should be analysed by SKU, format and order.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more on formulas, dashboards and management routines, read <a href=\"https:\/\/bulltec.it\/en\/?p=4688\">KPIs and OEE for the fruit and vegetable packing house<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Real-time control: data collection from machines and operators, alarms, set-up standards, audit trail<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Real-time control is the ability to see a problem as it arises, not at the end of the day. In a fruit and vegetable processing centre this means connecting three information sources: machines, operators and management systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Data from machines, operators and systems<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Machines generate valuable signals: speed, stoppage, alarm, counts, weights, waste, active recipes. Operators add the context: reason for the stoppage, batch change, visual non-conformity, packaging material problem, corrective action. The management system closes the loop with orders, item master data, labels, pallets and shipments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An effective architecture integrates at least these levels:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Machine<\/strong>: sensors, counters, weights, alarms.<\/li>\n\n\n\n<li><strong>Line control<\/strong>: dashboards, alerts, shift status.<\/li>\n\n\n\n<li><strong>MES or SCADA<\/strong>: events, recipes, process traceability.<\/li>\n\n\n\n<li><strong>ERP<\/strong>: orders, batches, warehouse, shipments.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In solutions such as <a href=\"https:\/\/bulltec.it\/en\/electronic-paddle-graders\/\">electronic paddle graders<\/a>, the machine software is already a practical lever because it allows processing parameters to be adjusted quickly. The real step change comes when this data does not remain isolated but feeds operational routines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Useful alarms and set-up standards<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You do not need a hundred alarms. You need a few clear alarms, each with a threshold, an owner and a defined action. Concrete examples:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>stoppage longer than x minutes;<\/li>\n\n\n\n<li>average weight out of range;<\/li>\n\n\n\n<li>giveaway above threshold;<\/li>\n\n\n\n<li>label inconsistent with the active order;<\/li>\n\n\n\n<li>waste above limit at a given stage;<\/li>\n\n\n\n<li>buffer full or empty in a critical area.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The same applies to set-ups. Every batch change or format changeover should have:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>a standard recipe;<\/li>\n\n\n\n<li>a start-of-shift check;<\/li>\n\n\n\n<li>confirmation of packaging material;<\/li>\n\n\n\n<li>verification of label data;<\/li>\n\n\n\n<li>an approved first sample;<\/li>\n\n\n\n<li>a recorded line release.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When these steps are not standardised, the line appears to work but operates in reactive mode.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Audit trail: who did what, when and on which batch<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">An audit trail is not bureaucracy. It is operational protection. In the event of a complaint or non-conformity, you need to be able to quickly reconstruct:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>incoming batch;<\/li>\n\n\n\n<li>processing date and time;<\/li>\n\n\n\n<li>active recipe;<\/li>\n\n\n\n<li>operator or person responsible for the change;<\/li>\n\n\n\n<li>label used;<\/li>\n\n\n\n<li>checks performed;<\/li>\n\n\n\n<li>pallets involved.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If this data is scattered across sheets, messages and staff memory, traceability exists only on paper. If, instead, it is recorded in an orderly way, it becomes possible to stop the problem, contain it and learn from its cause.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Precision and quality: reducing grading, packaging, labelling and batch management errors<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In the packing house, the most costly errors are not always the most glaring ones. Very often they are small but repeated errors that erode margin and customer trust for weeks before being recognised as systemic.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>High-impact errors<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The five errors that deserve top priority are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Mixed batches<\/strong>, because they compromise traceability.<\/li>\n\n\n\n<li><strong>Incorrect or outdated labels<\/strong>, because they generate non-conformities and returns.<\/li>\n\n\n\n<li><strong>Out-of-tolerance weights<\/strong>, both underweight and excessive giveaway.<\/li>\n\n\n\n<li><strong>Inconsistent grading<\/strong>, which leads to non-uniform product within the same pack.<\/li>\n\n\n\n<li><strong>Avoidable rework and waste<\/strong>, a symptom of an unstable process.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Many of these errors are amplified during format changeovers, batch changes and restart phases after a stoppage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Standards and checks that really reduce non-conformities<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Reducing errors requires simple, repeatable checks with clear responsibilities:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>start-of-shift check with confirmation of recipe, batch, material and line cleaning;<\/li>\n\n\n\n<li>periodic sampling of weight, size and pack presentation;<\/li>\n\n\n\n<li>label verification on the first piece and at every change;<\/li>\n\n\n\n<li>end-of-line check on compliance, integrity and correct pallet-batch association;<\/li>\n\n\n\n<li>non-conformity management with physical segregation and a recorded reason code.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Technology helps here, but method matters as much as the machine. For example, Bulltec highlights in its <a href=\"https:\/\/bulltec.it\/en\/electronic-paddle-graders\/\">electronic paddle graders<\/a> the gentle handling and the ability to work with parameters configurable according to the product. This is important because precision and productivity must not compromise the integrity of fresh produce. When pack weight control becomes critical, <a href=\"https:\/\/bulltec.it\/en\/combination-weighing-system\/\">combination weighing systems<\/a> can help reduce variability and giveaway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a more targeted list of recurring causes and countermeasures, see <a href=\"https:\/\/bulltec.it\/en\/common-mistakes-fruit-vegetable-packing-house\/\">Common mistakes in the fruit and vegetable processing centre and how to avoid them<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Hygiene, contamination and auditability<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Quality also means process hygiene. In a fruit and vegetable processing centre, there are at least three areas to monitor:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>cleaning and sanitising of lines, belts, contact points and tools;<\/li>\n\n\n\n<li>separation of dirty and clean areas and orderly waste management;<\/li>\n\n\n\n<li>pest management, environmental checks and recording of relevant events.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The right question is not only whether the plan exists, but whether it leaves verifiable records. You must be able to demonstrate when a line was cleaned, who reopened it, which checks were carried out and which batches passed through before and after a critical event. This auditability is an integral part of line control.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/bulltec.it\/wp-content\/uploads\/2026\/09\/chiusura-1024x683.webp\" alt=\"Vaschette di pomodorini confezionate in transito su linea di etichettatura automatica\" class=\"wp-image-4682\" srcset=\"https:\/\/bulltec.it\/wp-content\/uploads\/2026\/09\/chiusura-1024x683.webp 1024w, https:\/\/bulltec.it\/wp-content\/uploads\/2026\/09\/chiusura-300x200.webp 300w, https:\/\/bulltec.it\/wp-content\/uploads\/2026\/09\/chiusura-768x512.webp 768w, https:\/\/bulltec.it\/wp-content\/uploads\/2026\/09\/chiusura-1536x1024.webp 1536w, https:\/\/bulltec.it\/wp-content\/uploads\/2026\/09\/chiusura-2048x1365.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>30-60-90 day improvement roadmap + final checklist<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Improving a fruit and vegetable packing house does not start with a major investment, but with the right sequence. First make losses visible, then stabilise the fundamentals, and finally decide where to automate or integrate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>First 30 days: visibility and minimum standards<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the first month the aim is to create a reliable baseline:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>map the actual flow from reception to shipping;<\/li>\n\n\n\n<li>measure throughput per stage, stoppages, waste and rework;<\/li>\n\n\n\n<li>identify the main bottleneck;<\/li>\n\n\n\n<li>introduce start-of-shift and batch-change checks;<\/li>\n\n\n\n<li>define 5 or 6 standard downtime reason codes;<\/li>\n\n\n\n<li>verify the accuracy of weights and labels.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This phase already produces quick wins, because many losses stem from a lack of standards rather than from technological limits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Days 31-60: line balancing and management routines<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the second step, variability and waiting times need to be reduced:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>balance operators and capacity across stages;<\/li>\n\n\n\n<li>reduce changeovers and restart times;<\/li>\n\n\n\n<li>add buffers where they are really needed, not everywhere;<\/li>\n\n\n\n<li>hold short daily meetings with a Pareto of losses;<\/li>\n\n\n\n<li>define corrective actions with an owner and a deadline;<\/li>\n\n\n\n<li>stabilise preventive maintenance on constraint resources.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here it is useful to revisit the three pillars of this guide: numbers, flows and quality.

Without this figure, OEE, waste and lead time remain numbers disconnected from the operational flow. It should be measured at intake, after grading, at packaging and at the end of line, broken down by product, format and shift.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How do you identify the real bottleneck on the line?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The real bottleneck is the stage that consistently limits the output of the entire line, not the one that appears slowest at any single moment. To identify it you need to observe build-ups upstream, waiting downstream, resource saturation and micro-stop frequency, using hourly data and on-site walkthroughs. If packaging is running saturated while WIP is growing upstream, the constraint is there, even if other machines stop occasionally.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Do OEE and throughput measure the same thing?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">OEE and throughput do not measure the same thing, but they must be read together. Throughput tells you how much product actually leaves the line in a unit of time, while OEE explains why theoretical capacity does not turn into useful output, separating availability, performance and quality losses. A line can have acceptable throughput over a short shift and poor OEE because of slow format changeovers, high rework or recurring stoppages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How can labelling errors and mixed batches be reduced?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Reducing labelling errors and mixed batches requires simple but non-negotiable rules: only one batch open per workstation where possible, recipe linked to the production order, label code verification at format changeover and line stop in the event of a mismatch. It is essential to record who started the batch, which label was loaded, when the change took place and which packs were rejected. The combination of operational discipline, automatic checks and audit trail drastically reduces the risk of non-conformity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>When is it worth automating grading and weighing?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is worth automating grading and weighing when product variability, daily volume or the cost of giveaway make manual management unstable. Typical signs are rising waste, weight disputes, operator saturation at packaging and long set-up times between different product lines. In these cases, dedicated solutions such as electronic graders and combination weighing systems help standardise the result, increase repeatability and free up capacity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What data must be recorded to achieve real traceability?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To achieve real traceability you need to record at least the incoming batch ID, supplier or field, processing date and time, active recipe, operators present, quality checks carried out, average weights, waste, rework, labels used, pallets produced and shipping destination. This data must be retrievable within a few minutes both forwards and backwards, that is, from batch to shipment and from shipment to batch. If the information is scattered across sheets, whiteboards and operators&#8217; memory, traceability exists only on paper.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An efficient fruit and vegetable packing house is not judged solely by how many packs leave the line at the end of the shift.
