Filter Belt

Filter belt (filter cloth belt / belt filter media) is core filtration element for corn gluten belt filter press dehydrators. It represents the highest consumption frequently replaced spare part among dehydration equipment components. It is an endless woven filter media tensioned across the complete roller set of filter press. Upper and lower filter belts sandwich gluten slurry between them and travel synchronously. Through sequential stages: gravity dewatering, wedge zone pre compression, low pressure dewatering and high pressure dewatering; water contained within gluten is gradually squeezed out passing through filter belt media, forming final dry gluten filter cake.

Spiral Blade

Spiral blades (press blades / spiral segments) represent the most critical wear prone spare parts of corn gluten screw press dehydrators. These arc shaped plate components are welded onto dehydrator central shaft; directly contacting gluten material to realise conveyance and extrusion compression. As sub assembly elements of the auger, they suffer the most severe abrasive wear and require frequent replacement. After long term material extrusion and frictional scouring, blade outer edges and working surfaces gradually thin and deform, causing degraded dehydration efficiency and necessitating periodic replacement or hard facing weld repair.
