Development of an automatic juicer for minneola fruits [electronic resource].

Includes reference.

The aim of this research is to develop an automatic orange juicer for minneola fruits. This juicer consists of minneola feeding, minneola holding, cUlling, and press mechanisms to ,extract minneola jUice. The main results of this study can be summarized in the following points: increasing feeder speed and angle with horizontal axes increased number of dropped minneola fruits per minutes. The number of dropped minneoia-fruits per minute increased by about 27.5 to 56.14 % (from 17 - 28 to 35 - 57 fruit / minute) by increasing minneola feeding-mechanism speed from 7.54 to 22 rpm. There is no effect of the quantity of minneola fruits in hopper on number of dropped fruits per minutes· The fill rate of grooves of two drums holding mechanism was 100 % at all feeder speeds and angles and drum speed. The extraction ratio of juice of minneola fruits decreased from 49.85 to 49.26 % by increasing press balls and drums holder speed from 13 to 38 rpm. The highest machine-capacity (31.01 kg/min of minneola fruits and 15.28 Umin of juice) was obtained by using drums and balls speed of 38 rpm, and the iowest performance rate (10.61 kg/min of minneoia fruits and 5.29 Umin of juice) was obtained by using drums and balls speed of 13 rpm.
