Microwave hot air composite drying and puffing process for black soldier fly larvae

Abstract

The invention relates to a microwave hot air composite drying and puffing process for black soldier fly larvae. The process comprises the following steps of carrying out microwave inactivation on theblack soldier fly larvae; drying the inactivated black soldier fly larvae; taking the dried black soldier fly larvae for microwave puffing. The process further comprises the steps of pulverizing and packaging the puffed black soldier fly larvae. Compared with the prior art, the process has the advantages that finished products of the black soldier fly larvae which are dried and puffed by means ofthe process are loose, porous, plump in body shape and likely to be pulverized; microwave inactivation is carried out, a simultaneous internal and external heating mode is adopted, uniform heat distribution is achieved, the inactivation speed is higher, and a certain bactericidal effect is achieved at the same time; a microwave and hot air cooperative drying mode increases the drying speed, so that the black soldier fly larvae are dried uniformly; manpower is saved, the procedure is simple, the processing speed is high, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of processing black soldier fly larvae, and in particular relates to a microwave hot air composite drying and puffing process for black soldier fly larvae. Background technique [0002] Black soldier fly is a kind of saprophytic Soldier Fly insect. It can feed on poultry manure and domestic garbage to produce high-value animal protein feed. Low management and feeding costs, good animal palatability and other characteristics, so as to carry out resource utilization, its larvae are called "phoenix insects", and become resource insects with the same reputation as fly maggots, Tenebrio molitors, barley worms, etc., and are popular all over the world get promoted. Originated in the Americas, it has been introduced into my country in recent years, and has been widely distributed in Guizhou, Guangxi, Guangdong, Shanghai, Yunnan, Taiwan, Hunan, Hubei and other places. At present, it is widely used in the treatment...

AI Technical Summary

Problems solved by technology

[0003] Black soldier fly larvae contain high protein and rich nutritional value, and have high nutritional and economic value after drying. In the prior art, heat conduction equipment such as ovens are often used to dry black soldier fly larvae, which takes a long time to dry and destroys its own nutrition. Ingredients, after drying, the black soldier fly larvae are shriveled, and it takes a lot of labor and the production efficiency is low
