一种小型双螺旋低温榨油机的改进设计与试验

Improved design and test of a small twin-screw press in low temperature

为提高广大农村自给食用油的质量,推广低温榨油,对大中型双螺旋低温榨油机的榨螺进行创新改进,通过增加剪切环组和缩短螺旋来实现双螺旋榨油机的小型化。针对不同的油料,通过调整剪切环的个数及组数,组成专用榨螺结构。试验结果表明,改进后的设备出油量与中大型双螺旋低温榨油机相当,压榨效果较好。

The oil extracted by the low temperature twin-screw press is healthy.The structure of the low temperature twin-screw press is big and complicated,so it is not suitable for the rural market.In order to improve the quality of the oil for the peasants,a new small low temperature twin-screw press is improved and designed based on the large and media presses,which was composed of the srews,pressing and shearing rings.The shearing rings were new elements,which could shear the oilseed,increase the pressure and speed up the extrusion of the oil.The number and location of the shearing rings were adjusted to different structure of pressing bolts for different oil to receive the most oil.The result of the test showed that the oil extraction rate of the new small press was not lower than the common pres,and the effect of the oil expression was good.
