The sterilization temperature and duration are predetermined and automatically managed by the computer. <\/span><b>The most common temperature for autoclave sterilization is 121\u00b0C, but many cycles can reach higher temperatures, such as 132\u00b0C and 134\u00b0C. The water spray effectively transmits heat to the food containers to break down the bacterial and spore protein structures. <\/b><span style=\"font-weight: 400;\">This sterilizing procedure extends the shelf life of the food goods. The main benefit of an autoclave is &#8211; it washes away bacteria, literally. Water spray flows through the smallest schisms and gaps, maintaining a high-quality result. <\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-27e5904 elementor-widget elementor-widget-heading\" data-id=\"27e5904\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Hot air retorts<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bbab26f elementor-widget elementor-widget-text-editor\" data-id=\"bbab26f\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>In order to generate an overpressure in the retort, a mixture of flexible pressure steam and the air is added. This is called steam air type. Similar to water immersion and water spray, it is an over-pressure procedure, except instead of the water, the product is subjected to the effects of overpressure air.<b> The thermal processing of a wide range of containers, including glass, metal cans, rigid plastic, and flexible pouches, is made possible by air overpressure. The main benefit of steam and air technology is that it is as efficient as steam and water, but it is more cost-effective by using less energy. <\/b>The amount of energy needed to heat up air is far less than it is to heat up water. As a result, the cost is decreased and the heat treatment cycle lasts less time and is more consistent.<\/p><p>But which one is better? And again, there is no simple answer to this. <b>It depends on the product and packaging type. But, if we take fish processing, for example, specialists tend more toward the water type<\/b>. And why? Because traditionally fish canning factories have open-type baskets, which are designed for water spray. The autoclaves of direct steam use more closed-type baskets.. But, keep in mind, if you choose hot air retort it will be a more cost-effective choice.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-791e3c5 elementor-widget elementor-widget-image\" data-id=\"791e3c5\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-1024x1024.jpg\" class=\"attachment-large size-large wp-image-7628\" alt=\"\" srcset=\"https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-1024x1024.jpg 1024w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-300x300.jpg 300w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-150x150.jpg 150w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-768x768.jpg 768w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-1536x1536.jpg 1536w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-400x400.jpg 400w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-800x800.jpg 800w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor-100x100.jpg 100w, https:\/\/peruza.com\/wp-content\/uploads\/2022\/11\/Manualais_autoklava_gr_iek_with-floor.jpg 2000w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-57fda12 elementor-widget elementor-widget-text-editor\" data-id=\"57fda12\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Source: <\/span><a href=\"https:\/\/peruza.com\/solution\/autoclave-basket-unloader\/\"><span style=\"font-weight: 400;\">PERUZA<\/span><\/a><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b242c13 elementor-widget elementor-widget-heading\" data-id=\"b242c13\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">PERUZA\u2019S Autoclave basket loader and autoclave basket unloader<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6c76631 elementor-widget elementor-widget-text-editor\" data-id=\"6c76631\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">PERUZA offers two amazing solutions for those who have chosen to work with autoclaves.&nbsp;<\/span><\/p>\n<p><\/p>\n<p><span style=\"font-weight: 400;\"><a href=\"https:\/\/peruza.com\/solution\/autoclave-basket-loader\/\">The autoclave basket loader <\/a>and<a href=\"https:\/\/peruza.com\/solution\/autoclave-basket-unloader\/\"> the basket unloader <\/a>are made to load and unload specified kinds of autoclave or retort baskets.
