In order to provide an efficient,safe and practical machinery for shredding mulberry branches in large scale production of base materials for raising edible fungi,we designed and developed a multi-purpose branch shredder Model QCF50 with standardized designing in accordance with the standards stipulated by the nation and the ministry.This machine is composed of a frame,an engine and other work pieces.It integrates cutting,crushing and sieving processes in its operation.The transmission and material feeding,manufacturing and discharging are all run under safeguard condition.Through designing and computing major technical parameters,selecting adequate material,configuring rotation speed of the main shaft,and using different sieve plates for different shredding purposes,performance of the machine is reliable and safe.The productivity of the sample machine reached 1 000 kg/h when branches were processed and was 1 500 kg/h when round logs and wood bars were processed.And the shredded material reached the quality requirement of base material for raising edible fungi.
