Description

Technical Field

[0001] The utility model relates to the technical field of microwave drying, and more specifically, to a microwave drying device. Background Art

[0002] Black soldier flies, saprophytic insects of the family Solenopsis, can feed on livestock and poultry manure and domestic garbage to produce high-value animal protein feed. Due to their rapid reproduction, large biomass, wide-ranging diet, high absorption conversion rate, easy management, low feeding cost, and good animal palatability, they are used as resources and promoted worldwide. Currently, they are widely used in the treatment of wastes such as chicken manure, pig manure, and kitchen waste. When drying and storing black soldier flies, most of them are dried by microwave generators. Therefore, a microwave drying device is proposed for drying black soldier flies.

[0003] After searching, for example, a Chinese patent application with application number CN202020259472.X discloses a microwave drying device for black soldier flies. When the utility model is working, the cloth motor drives the cloth screw to rotate, and the rotation of the cloth screw causes the insect bodies at the bottom of the feed hopper to be evenly conveyed to the two ends of the cloth tube, and the insect bodies then fall evenly from the cloth strip holes to the conveyor mesh belt distributed in a stepped manner, which solves the problem of uniform cloth distribution of live insects and prevents the live insects from being piled together, thereby achieving automatic uniform cloth distribution without manual assistance, saving labor; when the insect bodies are conveyed in steps, due to the existence of the height difference, the insect bodies can be effectively turned over, ensuring that the insect bodies are heated evenly, improving the drying effect, and thus making the quality of the dried insect bodies better; the stepped conveyor mesh belt is driven by the same motor, and the structural layout design is reasonable; the utility model can meet the requirements of flow operation and carry out large-scale continuous operation, and can be widely used in the field of black soldier flies drying.

[0004] However, when the above technical solution is used, the black soldier flies are poured into the feed hopper, and the black soldier flies are dispersed and distributed by the distribution tube, the distribution strip holes and the distribution screw. The black soldier flies are of different sizes. The smaller black soldier flies will be stuffed between the distribution tube and the distribution screw, and the larger black soldier flies will be squeezed and damaged due to the small gap between the rotating distribution screw and the distribution tube, thereby reducing the qualified rate of the finished black soldier flies. In addition, the above solution does not have a mechanism for discharging water vapor, so that the moisture after drying is retained in the drying box, resulting in liquefied falling water droplets, which are easy to drip onto the dried black soldier flies, affecting the quality of the finished black soldier flies.
