Abstract

At present juice recovery from sugarcane using conventional power crushers is about 60 percent. Nearly 10-20 per cent of juice goes as waste along with bagasse. For increased juice recovery, an improved four roller crusher has been developed. It consisted of rollers, gear train, feed chute, bagasse carrier, juice collection tray and juice outlet. The performance of this crusher over three roller vertical and horizontal crusherr was evaluated and compared in terms of capacity, energy consumption and juice extraction efficiency. Juice extraction efficiency was found to be 11 and 8 per cent higher than that of the vertical and horizontal type three roller crusher respectively.

Keywords: Juice extraction efficiency, Capacity, Roller clearance.
