Triowin equipment has different treatment processes in the processing of different fruit species, and stone fruit juice extraction needs to be pitted in the early stage. After the material enters the sieve drum, the slewing action of the scraper and the existence of the lead angle make the material move along the cylinder to the outlet end, and the trajectory is a spiral, and the material is broken by centrifugal force during the movement between the scraper and the sieve drum. The juice and flesh (already pulped) are sent from the sieve hole through the collector to the next process, and the skin and kernel (seeds) are discharged from the other open end of the cylinder to achieve separation.
