Working Principle: 

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 simplified fluid bed 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 with ribbon type agitator, draft fan and hot air heater. The conical part of drying chamber is made by perforated plate. Wet material (BSF larvae or fly maggots) 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, meanwhile 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:

• 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 150 ℃, it just takes about 60-70 minutes to dry one batch from 70-75% to 5-7% moisture content and the larvae or maggots can be roasted to get popped product.
• Uniform Drying: The regular movement of larvae inside the drying chamber and the specially designed hot air distribution chamber can make sure hot air evely flow through the wet material for uniform drying. 
• Flexible heat source: Our agitator dryer can work with different heat sources, such as electricity, steam, thermal oil or gas/oil fired hot air generator. 
• 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.
• Large drying capacity with compact machine: The biggest drying capacity can be 500 kg/h with a 1500L drying chamber. Different capacity is available from 50 kg/h to 500 kg/h.
