Abstract

Pulpers available in market have two concentric drums, one for sieving the crushed fruit pulp and other serve as housing. A motorized single drum brush type watermelon pulper was designed and fabricated unlike the available pulper in market. The pulper designed was simple, low cost, high capacity and easy to operate and required less cleaning effort and time. The pulper consist of the feed hopper, choppers, screw conveyor, cylindrical main housing with baffles, a perforated screen, juice outlet, waste outlet and a shaft with two beaters and nylon brushes. The auger conveyed the chopped fruit pieces while the beaters/brushes crushed, pressed and squeezed the fruits to extract the pulp. The motor, extraction unit shaft and chopper shaft had speed 1440, 360 and 90 respectively for effective pulp recovery. The developed pulper has an overall dimension of 890 mm × 300 mm × 300 mm and weighed 33.20 kg. The pulper has an average throughput of 1100 kg/h with an average extraction efficiency of 90.14 percent.

基于破碎和剪切力力学作用的西瓜碎浆机研制及性能评价
市场上的纸浆机有两个同心滚筒,一个用于筛碎果肉,另一个用作外壳。设计并制造了一种不同于市场上现有的电动单滚筒刷式西瓜碎浆机。所设计的制浆机结构简单、成本低、处理量大、操作方便、清洗费时少。该制浆机由进料斗、切碎器、螺旋输送机、带挡板的圆柱形主壳、穿孔筛网、出汁口、出渣口和带有两个打蛋器和尼龙刷的轴组成。螺旋钻输送切碎的水果块,而搅拌器/刷子将水果粉碎、压榨和挤压以提取果肉。电机转速为1440、抽提机组轴转速为360、斩浆轴转速为90,可有效回收矿浆。研制的制浆机外形尺寸为890毫米× 300毫米× 300毫米,重33.20公斤。该制浆机平均输送量为1100公斤/小时,平均萃取效率为90.14%。
