cooler<\/strong><\/p><p><strong>Wet vacuum cooler<\/strong><\/p><p>Although terminology differs, these descriptions can refer to the same fundamental concept: <strong>rapidly removing heat using evaporation under reduced atmospheric pressure<\/strong>.<\/p><p>Cold Change specialises in <strong><a href=\"https:\/\/coldchange.com\/es\/product-category\/cold-chain-products\/pre-coolers\/vacuum-cooling\/\">commercial vacuum cooling equipment<\/a><\/strong> designed specifically for demanding industrial applications.<\/p><hr \/><h1>Why Is <a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\">Vacuum Cooling<\/a> So Effective for Leafy Vegetables?<\/h1><p>Leafy vegetables are particularly well suited to vacuum cooling because of their structure and high surface-area-to-mass ratio.<\/p><p>Products such as:<\/p><p><strong>Iceberg lettuce<br \/>Romaine lettuce<br \/>Cos lettuce<br \/>Leaf lettuce<br \/>Baby leaf<br \/>Spinach<br \/>Rocket<br \/>Arugula<br \/>Watercress<br \/>Cabbage<br \/>Pak choi<br \/>Bok choy<br \/>Kale<br \/>Swiss chard<br \/>Fresh herbs<br \/>Celery<br \/>Broccoli<br \/>Cauliflower<br \/>Spring onions<br \/>Green onions<br \/>Leeks<br \/>Asparagus<br \/>Brussels sprouts<br \/>Sweetcorn<\/strong><\/p><p>can potentially benefit from rapid post-harvest cooling, depending on the product and processing requirements.<\/p><p>Rather than waiting for refrigerated air to gradually penetrate boxes, pallets and layers of produce, a correctly designed <strong>vegetable vacuum cooler<\/strong> can remove heat rapidly throughout the load.<\/p><p>This makes <a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\"><strong>vacuum pre-cooling<\/strong><\/a> particularly attractive for high-throughput fresh produce packhouses.<\/p><hr \/><h1>Removing Field Heat Immediately After Harvest<\/h1><p>Harvesting doesn&#8217;t stop biological activity within fresh produce.<\/p><p>Once crops are removed from the field, temperature becomes one of the most important factors affecting subsequent quality and storage.<\/p><p>Freshly harvested vegetables can arrive at the packhouse carrying significant <strong>field heat<\/strong>.<\/p><p>Rapid <strong>post-harvest pre-cooling<\/strong> is therefore used to reduce product temperature as quickly as practically possible before refrigerated storage and transportation.<\/p><p>This is one of the principal reasons growers invest in dedicated <strong><a href=\"https:\/\/coldchange.com\/es\/product-category\/cold-chain-products\/pre-coolers\/\">pre-cooling equipment<\/a><\/strong> rather than relying entirely on their cold rooms.<\/p><p>A cold room is excellent at <strong>maintaining<\/strong> temperature.<\/p><p>A pre-cooler is designed to <strong>remove heat rapidly<\/strong>.<\/p><p>These are two different jobs.<\/p><hr \/><h1><a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\">Vacuum Cooling<\/a> vs Conventional Cold Rooms<\/h1><p>Putting warm lettuce or leafy vegetables directly into a cold room does not necessarily mean the centre of the product will cool rapidly.<\/p><p>Heat removal can depend upon:<\/p><ul><li><p>Air velocity<\/p><\/li><li><p>Packaging<\/p><\/li><li><p>Ventilation<\/p><\/li><li><p>Pallet arrangement<\/p><\/li><li><p>Product density<\/p><\/li><li><p>Starting temperature<\/p><\/li><li><p>Refrigeration capacity<\/p><\/li><li><p>Air distribution<\/p><\/li><\/ul><p><a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\">Vacuum cooling<\/a> works differently.<\/p><p>Inside a <strong><a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\">vacuum cooling<\/a> chamber<\/strong>, reduced atmospheric pressure allows evaporative cooling to occur throughout suitable produce.<\/p><p>For large palletised loads, this can provide much faster and more uniform temperature reduction than simply placing warm produce into refrigerated storage.<\/p><hr \/><h1><a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\">Vacuum Cooling<\/a> vs Blast Chilling<\/h1><p>Another common method of rapidly reducing product temperature is <strong>blast chilling<\/strong> or forced-air cooling.<\/p><p>Cold Change also supplies a complete range of <strong><a href=\"https:\/\/coldchange.com\/es\/product-category\/cold-chain-products\/pre-coolers\/cooling-harvest\/\">commercial blast chillers<\/a><\/strong> for applications where forced-air cooling is more appropriate.<\/p><p>Blast chilling uses high-velocity refrigerated air to remove heat.<\/p><p>Vacuum cooling uses evaporation under reduced pressure.<\/p><p>Neither technology is universally better for every product.<\/p><p>The correct cooling method depends on the crop, packaging, throughput, starting temperature, final temperature, moisture characteristics and processing operation.<\/p><p>For highly suitable leafy products, however, <strong>vacuum cooling can achieve exceptionally rapid cooling<\/strong>.<\/p><hr \/><h1><img decoding=\"async\" class=\"alignnone

Cooling<\/h1><p><strong>Hydro cooling<\/strong> uses chilled water to remove heat from produce.<\/p><p>Cold Change supplies a dedicated range of <strong><a href=\"https:\/\/coldchange.com\/es\/product-category\/cold-chain-products\/pre-coolers\/hydro-cooling\/\">hydro cooling systems<\/a><\/strong> for products where direct chilled-water cooling is appropriate.<\/p><p>Hydro cooling can be particularly effective for certain robust fruits and vegetables.<\/p><p>Vacuum cooling, however, can be advantageous for leafy vegetables because the cooling mechanism occurs throughout suitable produce without requiring the complete product load to be submerged in chilled water.<\/p><p>The best technology should always be selected according to the specific crop and operation.<\/p><hr \/><h1>What Is Hydro-Vacuum Cooling?<\/h1><p>You may also encounter the terms <strong>hydro-vac, hydro vacuum cooling, wet <a href=\"https:\/\/coldchange.com\/es\/vacuum-coolers\/\">vacuum cooling<\/a> or wet vacuum pre-cooling<\/strong>.<\/p><p>A hydro-vacuum system combines vacuum cooling with controlled water addition.<\/p><p>During conventional vacuum cooling, a small quantity of moisture evaporates from the product as part of the cooling process.<\/p><p>For certain products, introducing controlled moisture can help compensate for some of this moisture loss.<\/p><p>This allows growers to combine the speed of <strong>vacuum cooling<\/strong> with additional moisture management.<\/p><hr \/><h1>Vacuum Cooling Lettuce<\/h1><p>Lettuce is one of the products most closely associated with commercial vacuum cooling.<\/p><p>Iceberg lettuce, cos lettuce, romaine lettuce and other leafy varieties can contain considerable field heat when harvested during warm conditions.<\/p><p>Rapid cooling before storage and transportation can therefore form an important part of maintaining product quality.<\/p><p>For growers producing large quantities of lettuce, a dedicated <strong>lettuce vacuum cooler<\/strong> can process entire pallet loads rather than relying on gradual cooling inside a cold room.<\/p><p>Cold Change supplies systems ranging from a <strong><a href=\"https:\/\/coldchange.com\/es\/product\/vacuum-cooler-single-pallet\/\">single pallet vacuum cooler<\/a><\/strong> for smaller operations through to large multi-pallet systems for industrial packhouses.<\/p><hr \/><h1>Vacuum Cooling Spinach, Baby Leaf and Salad Crops<\/h1><p>Spinach, baby leaf, rocket, watercress and mixed salad crops are highly temperature-sensitive products.<\/p><p>Once harvested, establishing the cold chain quickly can be extremely important.<\/p><p>A correctly selected <strong>leafy greens vacuum cooler<\/strong> can rapidly reduce temperature before the produce moves into cold storage, packing, distribution or refrigerated transportation.<\/p><p>This makes vacuum cooling particularly relevant to growers supplying:<\/p><p><strong>Supermarkets, salad processors, wholesalers, foodservice companies, fresh-cut processors and export markets.<\/strong><\/p><hr \/><h1>Vacuum Cooling Broccoli and Cauliflower<\/h1><p>Vacuum cooling isn&#8217;t limited to lettuce.<\/p><p>Broccoli and cauliflower are also important fresh produce applications where rapid post-harvest temperature reduction can be beneficial.<\/p><p>Cold Change vacuum cooling equipment is designed for a wide range of vegetable applications and can be customised around product weight, pallet arrangement and required throughput.<\/p><p>Growers handling multiple crops can therefore potentially use the same <strong><a href=\"https:\/\/coldchange.com\/es\/product-category\/cold-chain-products\/pre-coolers\/vacuum-cooling\/\">industrial vacuum cooling system<\/a><\/strong> across several suitable product lines.<\/p><hr \/><h1>Vacuum Cooling Mushrooms<\/h1><p>Mushrooms are another major commercial application for vacuum cooling.<\/p><p>Because mushrooms can deteriorate quickly after harvesting, rapid temperature reduction can be particularly valuable.<\/p><p>If mushrooms form part of your operation, see our dedicated guide to <strong>vacuum cooling mushrooms<\/strong> in the Cold Change News &amp; Insights section.<\/p><p>Our <strong><a href=\"https:\/\/coldchange.com\/es\/product-category\/cold-chain-products\/pre-coolers\/vacuum-cooling\/\">vacuum cooler range<\/a><\/strong> can be configured

large-scale cooling.<\/p><hr \/><h1>Choosing Vacuum Cooler Capacity by Tonnes per Hour<\/h1><p>The number of pallets that fit inside the chamber is only part of the calculation.<\/p><p>A commercial <strong>vacuum cooling machine<\/strong> should ideally be selected around your actual production requirements.<\/p><p>Important factors include:<\/p><p><strong>Product type<br \/>Kilograms per pallet<br \/>Number of pallets per batch<br \/>Incoming product temperature<br \/>Required final temperature<br \/>Required cooling time<br \/>Loading time<br \/>Unloading time<br \/>Cycles per hour<br \/>Tonnes per hour<br \/>Daily operating hours<br \/>Harvest peaks<br \/>Future production growth<\/strong><\/p><p>For example, two 10-pallet operations can have completely different cooling requirements if one loads 250 kg per pallet and another loads 700 kg per pallet.<\/p><p>This is why Cold Change can provide <strong>customised vacuum cooling solutions<\/strong> rather than simply supplying equipment according to chamber capacity.<\/p><hr \/><h1>How Long Does Vacuum Cooling Take?<\/h1><p>There isn&#8217;t one universal vacuum cooling time.<\/p><p>Cycle duration depends
