With additional washing functions, Vertical Centrifuge machine has a better cleaning effect. A pneumatically assisted scraper is adopted to remove the remnant filter cake and the CIP system is optional to secure clarity to be in accordance with GMP Norm, complementing the precision separation performance of the rectangular separator. A frequency control system is adopted to ensure a stable start-up. PLC is adopted to ensure complete automatic processes. No need for human supervision, making the Vertical Centrifuge machine and matching rectangular separator a reliable combination for automated material handling. This rectangular separator works as a gyratory separatorr in the overall automated line, helping deliver consistent screening performance while matching the CIP-ready, PLC-controlled centrifuge process.
