Dewatering solution for spent grain
Achieve efficient moisture reduction in spent grains with this continuous mechanical screw press, enhancing product shelf life and reducing transportation costs.

Reduces Moisture in Spent Grains
The Model DW 8 Series from The Bonnot Company is a robust dewatering extruder designed to address moisture challenges in spent grains for breweries, distilleries, and agricultural businesses. Utilizing a continuous mechanical screw press, this equipment effectively reduces grain moisture to approximately 60%, facilitating its use in producing cattle feed pellets, fertilizers, and other products. The extrusion process ensures efficient separation and pressing capabilities, contributing to significant weight reduction for easier storage and transport while extending shelf life. With a processing capacity of up to 2,000 lbs per hour, the DW 8 Series integrates seamlessly into existing production lines, supported by PLC controls for optimized operation. Constructed with replaceable stainless steel screens, the extruder promises durability and ease of maintenance. Optional custom engineering and feasibility testing are available, ensuring tailored solutions for specific operational requirements.
