Process Requirements

Typical materials: Flour, sugar, rice, starch, seasoning, milk powder, grains and food pellets.

Application challenge: Food contact surfaces require appropriate material, smooth finish, clean access and careful control of product retention.

FUWEI recommendation: Use stainless steel contact parts, hygienic seals, polished surfaces and quick-disassembly designs where sanitation is critical.

Recommended Valve Configurations

Contact material	Food-contact stainless steel selected for the process
Finish	Smooth or polished surfaces to reduce material retention
Cleaning	Quick-disassembly rotor access and removable components
Product care	Rotor speed and clearance selected for gentle transfer

Recommended FUWEI Products

Final model selection should confirm material name, bulk density, particle size, moisture, required capacity, temperature, pressure difference, flange standard and motor requirement.
