Description
Известен способ сушки гранулированных комбикормов дл рыб, согласно которому гранулы обрабатывают в несколько стадий пропусканием используемого однократно нагретого воздуха сквозь слой продукта.There is a known method of drying granulated animal feed for fish, according to which the granules are processed in several stages by passing the used heated air through a layer of product.
Предлагаемый снособ позвол ет сохранить в гранулах белки и витамины и ускорить сушку . Он отличаетс тем, что температуру воздуха снижают от первой стадии к последней, причем на первой стадии она составл ет 130- 155° С, на последней 58-60С, а врем обработки гранул на первой стадии должно быть достаточным дл образовани корочки и прогревани их не выше чем до 60° С.The proposed method allows preservation of proteins and vitamins in the granules and speeding up the drying. It differs in that the air temperature is reduced from the first stage to the last, and in the first stage it is 130-155 ° C, at the last 58-60 ° C, and the processing time of the granules in the first stage should be sufficient to form a crust and heat them up. higher than 60 ° C.
На первой стадии гранулы сушат в течение 3-4 мин при скорости воздуха 0,8-1 м/сек и толшине сло гранул 8-10 мм; на второй стадии - в течение 4-5 мин при температуре воздуха 90-95° С, скорости 0,8-1 м/сек и толщине сло гранул 10--12 мм; на третьей - в течение 7-8 мин при температуре воздуха 58- 60°С, скорости 0,8-1 м/сек и толшине сло гранул 15-18 мм; на четвертой - в течение 13-15 лшн при скорости воздуха 0,8-1 м/сек при толщине сло гранул 20-30 мм.In the first stage, the granules are dried for 3-4 minutes at an air speed of 0.8-1 m / s and the thickness of the layer of granules is 8-10 mm; in the second stage - within 4-5 minutes at an air temperature of 90-95 ° C, a speed of 0.8-1 m / s, and a thickness of a layer of granules 10-12 mm; on the third - within 7-8 minutes at an air temperature of 58-60 ° C, a speed of 0.8-1 m / s and a thickness of the layer of granules 15-18 mm; on the fourth - for 13-15 ppm at an air speed of 0.8-1 m / s with a thickness of a layer of granules 20-30 mm.
не поднимаетс выше 60° С, что гарантирует сохраниость в них белков и витаминов.does not rise above 60 ° C, which guarantees the preservation of proteins and vitamins in them.
