Drying device for edible/medical/feed insects

Abstract

The invention discloses a drying device for edible / medical / feed insects. A carbon dioxide gas inlet pipe is arranged on the side wall of a heat preservation drying box body, one end of the carbon dioxide gas inlet pipe extends into the bottom of the heat preservation drying box body, and the other end of the carbon dioxide gas inlet pipe extends out of the box body to be connected with a carbon dioxide gas inlet valve. The top end of the heat preservation drying box body is provided with an exhaust opening, and the bottom end of the heat preservation drying box body is provided with a gas inlet. The exhaust opening is connected with a hot air outlet pipe which is provided with a one-way air pressurizing valve, and the position, between the one-way air pressurizing valve and the exhaust opening, on the hot air outlet pipe is further provided with a carbon dioxide gas outlet valve. The other end of the hot air outlet pipe is connected with a silica gel drier, a filter, an air heater and a hot air inlet pipe in sequence. The hot air inlet pipe is connected with the gas inlet, and the one-way air pressurizing valve is installed on the hot air inlet pipe. A plurality of layers of trays are arranged in the heat preservation drying box body, and the bottoms of the trays are in screen shape. A movable door is further arranged on the heat preservation drying box body, a temperature controller is arranged in the heat preservation drying box body, and the temperature controller is electrically connected with the air heater.

Description

Technical field: [0001] The invention belongs to the field of insect drying, and in particular relates to a drying equipment for edible / medicinal / feeding insects. Background technique: [0002] Insects account for about 60% of the entire animal kingdom and are a huge resource bank. Insects have broad application prospects in emerging industries in the fields of agriculture, biomedicine, food and health products, feed industry, and fine chemicals. Insects are rich in protein and various active substances, and are rich in nutrition. However, the water content of living insects is very high, generally more than 70%. Therefore, the drying of insects is one of the important processing procedures for insect utilization. Excessively high drying temperature will lead to denaturation of insect protein and active substances, which is not conducive to subsequent utilization. However, at present, vacuum freeze-drying is beneficial to maintain the activity of insect proteins and acti...

Problems solved by technology

Excessive drying temperature will lead to denaturation of insect protein and active substances, which is not conducive to subsequent utilization

However, at present, vacuum freeze-drying is beneficial to maintain the activity of insect proteins and active substances, but it has disadvantages such as high equipment investment cost, high follow-up processing cost, and long time-consuming, which is not conducive to commercial application.
