Black soldier fly larvae (or maggots, larva insects) are increasingly attracting the attention of livestock industry as an alternative source of protein. These larvae / maggots can convert organic waste into protein for animal consumption, whilst also changing waste into a product that can be used, for example, as compost. Their remarkable ability to transform nearly any kind of organic waste into protein could revolutionize global food supplies. 

Agitator Dryer is a simple fluid-bed type dryer with ribbon agitator, which is specially designed for drying black soldier fly larvae (or maggots, larva insects) with affordable price. The dryer consists of a conical drying chamber and a ribbon type agitator. The conical part of drying chamber is made by perforated plate. Wet material is fed by gravity into the drying chamber via the feed valve. With the help of rotary ribbon agitator, wet material regularly moves up against the inner conical wall and then falls down in the center, hot air flows through the wet material for uniform and fast drying. The dried product is unloaded from the bottom discharge valve. 


For drying BSF larvae/maggots, our Agitator Dryer has the following overwhelming advantages: 

1. Short drying time: The dryer works in batch operation so the drying time can be controlled according to different working conditions. When the inlet hot air temperature is 120 ℃, it just takes about 60 minutes to dry one batch from about 70% to 5% moisture content for fresh larvae or maggots. When increase the hot air temperature to 200 ℃, the larvae or maggots can be roasted to get pop product. 

2. Uniform Drying: The regular movement of wet material inside the drying chamber and specially designed hot air distribution chamber can make sure hot air evely flow through the wet material. 

3. Flexible heat source:  Our agitator dryer can work with different heat sources, such as electricity, steam, thermal oil or hot air generator by burning coal, biomass fuels, oil, gas etc.  

4. Affordable price: Our agitator dryer is quite simple, compact, reliable, easy to operate and clean. And the price is much lower compared to microwave dryer. belt dryer or vacuum disc dryer. 

5. Large drying capacity with compact machine. The biggest drying capacity can be 1 ton/h with a 1500L drying chamber. Different capacity 30 -1000 kg/h is available.
