Изобретение относится к вакуумным технологическим процессам обработки веществ и материалов, в частности к вакуумной термической обработке и обезгаживанию, в том числе пищевых продуктов, а также продуктов жизнедеятельности животных и птиц в отраслях промышленного животноводства и птицеводства, шламов сточных вод различного происхождения и т.п. Для снижения влажности конечного продукта ниже 15% при способе вакуумной сушки, включающем нагрев обрабатываемого продукта до 60 - 70°С при давлении над поверхностью обрабатываемого продукта 70 - 150 мм рт.ст. и перемешивание обрабатываемого продукта с частотой мешалки до 10 мин-1, нагрев обрабатываемого продукта в вакууме осуществляют до температуры не выше (100 + 10)°С при соотношении объема загруженного обрабатываемого продукта и рабочего объема вакуумной технологической камеры 1: 10, и ведут процесс вплоть до получения в технологической камере давления (5 •10)-2 мм рт.ст. Причем в процессе нагрева и откачки обрабатываемый продукт поддерживается в состоянии "кипящего слоя".The invention relates to vacuum technological processing of substances and materials, in particular to vacuum heat treatment and degassing, including food products, as well as waste products of animals and birds in the sectors of industrial animal husbandry and poultry farming, sludge wastewater of various origin, etc. To reduce the humidity of the final product below 15% with the method of vacuum drying, which includes heating of the processed product to 60 - 70 ° C at a pressure above the surface of the processed product 70 - 150 mm Hg. and mixing the processed product with a stirrer frequency of up to 10 min -1 , heating the processed product in vacuum is carried out to a temperature not higher than (100 + 10) ° C with a ratio of the volume of the processed product loaded and the working volume of the vacuum process chamber 1:10, and the process is carried out until pressure in the process chamber is (5 x 10) -2 mm Hg. Moreover, in the process of heating and pumping the processed product is maintained in the "fluidized bed" state.
