Black soldier flies, saprophytic soldier fly insects, can feed on livestock manure and domestic waste to produce high-value animal protein feed. It can be used for resource utilization due to its fast reproduction speed, large biomass, wide food habit, high absorption and transformation rate, convenient management, low feeding cost, and good animal palatability. Its larvae are called "Phoenix worms", which have become the same famous resource insects as fly maggots, mealworms, barley worms, etc., and have been promoted worldwide.

The outstanding advantages of black soldier fly larvae drying equipment: the tumble dryer is used to treat black soldier flies, which has many outstanding advantages compared with conventional methods, the processing time is greatly shortened, the output is large, easy to control, the product quality is good, and the worm body is straight , high puffing degree, can maintain color and freshness, less loss of water and nutrients, low bacterial content, high processing efficiency, low cost, low energy consumption, small footprint.

Working process: Fresh larvae enter the dryer, are evenly distributed on the drum feed tray and the tower tube rotation, and fully contact with the steam tube heat exchanger to achieve heat transfer, mass transfer, low temperature drying, water evaporation and dispersion. As the air is discharged, the moisture of the material in the BSF gradually decreases, and the BSF completes the drying process.
