文档介绍：摘要

在果蔬的破碎、提取汁液的工艺上,有机械榨取、理化和酶法提取三种方法。但理化和酶法提取因其适应性的局限和副作用的产生而在使用上收到限制。机械式榨取果汁蔬液广泛应用在番茄、菠萝、苹果、柑橘、橙的压榨上。螺旋式连续榨汁机就是机械法榨汁的主要机械与设备之一。螺旋式连续榨汁机是采用压缩体积的方式使果料的固体与液体成分分离,榨取汁液。可以为中型食品企业和餐饮业提供榨汁的需要,是一种常用的食品机械。本设计的螺旋式连续榨汁机介绍了以压缩体积为基础的榨汁机的设计要点、工作原理和设备组成。设计主要通过变螺距变径螺杆,让榨汁机能充分榨出果蔬汁液。它的特点是结构简单,外形尺寸小,榨汁效率高,操作很方便,故在食品工厂广泛使用。

Abstract
Broken in fruits and vegetables, the juice extraction process, mechanical extract,chemical and enzymatic extraction of three methods. However, because of the physical and chemical and enzymatic extraction adaptability limitations and side effects produced and received restrictions on use. Mechanical liquid vegetable juice extract is widely used in the
tomato, pineapple, apple, citrus, orange crush. Continuous spiral juicer is one of the main machinery and equipment mechanical method juice. Screw Continuous juicing machine is used in a way that the volume pressed fruit material separating solid and ponents, the extraction of juice. Juicing can provide needed food for medium-sized businesses and restaurants, is monly used food machinery. The design of the continuous spiral juicer introduced press the volume-based design points juicer, working principle and equipment. Designed primarily by variable pitch screw adjustable, allowing fully functional juice squeezed fruit and vegetable juices fluid. It is characterized by simple structure, small size, high efficiency juice, the operation is very convenient, it is widely used in food factories.
Key words : mechanical extract ;press ;the spiral continuous juicer ; food machinery
