AI Technical Summary
Existing starch extraction centrifuge screens are prone to clogging, resulting in incomplete separation of starch and fine fibers, which affects the continuous operation of the equipment.
A starch extraction centrifugal sieve including a backwashing unit and a rinsing unit was designed. The sieve cylinder is backwashed by a high-pressure pump and a spray pipe system to remove blockages. The sieve is made of stainless steel mesh and copper spray pipes, combined with a centrifugal structure to achieve separation.
This effectively avoids screen clogging, improves the separation effect of starch and fine fiber, and ensures continuous operation of the equipment.
