Low-temperature non-oxidation drying machine and imago body drying method

Abstract

The invention relates to the field of drying machines, and discloses a low-temperature non-oxidation drying machine. The low-temperature non-oxidation drying machine comprises a water-gas separation assembly, a drying assembly and a non-oxidation gas heating and conveying assembly used for heating and conveying non-oxidation gas. The non-oxidation gas heating and conveying assembly is connected tothe drying assembly and the water-gas separation assembly, the drying assembly is connected with the water-gas separation assembly, and therefore gas circulation can be formed among the non-oxidationgas heating and conveying assembly, the water-gas separation assembly and the drying assembly. According to the low-temperature non-oxidation drying machine, imago bodies are dried through the low-temperature non-oxidation gas and are prevented from being oxidized in the drying process; and because of low-temperature drying, activity of beneficial bacteria in the imago bodies can be kept, and functionality, use value and market value of the imago bodies are greatly improved.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a low-temperature non-oxidizing dryer. Background technique [0002] In order to increase the storage time of the worm body, or because the dried worm body can be used as animal feed or plant fertilizer and the like. It is necessary to use drying equipment to dry the insect body. Take the black soldier fly as an example. The adult black soldier fly is rich in protein. After drying the adult black soldier fly, protein feed and raw materials for deep-processing products can be obtained, which has high use value and market value. [0003] The drying method of the traditional dryer generally adopts to directly feed air into the dryer, then heat the air to a higher temperature, and then blow the hot air to the insect body through a fan for drying. [0004] The defect of this drying method is that: since the gas that is passed in is air, and a part of oxygen is mixed in the air, when ...

AI Technical Summary

Problems solved by technology

[0004] The defect of this drying method is that: since the gas that is passed in is air, and a part of oxygen is mixed in the air, when the air is used to dry the worm body, the worm body will be damaged under high temperature and aerobic environment. Oxidation or even burning, this drying method will destroy the activity of beneficial bacteria in the insect body, seriously damage the functional value, use value and market value of the insect body
