题目：甘蔗榨汁机的应用设计

摘要

在压碎甘蔗和提取果汁的过程中，有三种机械提取，物理化学提取和酶提取的方法。但物理和化学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，因而这两种机械提取方法没有得到广泛使用。机械压榨的种类通常用于压榨番茄，菠萝，苹果，柑橘类水果和橙子。压轨机是机械果汁提取最重要的机器和设备之一。压力车昆式连续榨汁机通过压缩体积来分离果实的固体和液体成分，并提取果汁。能够为食品行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•的压輕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。设计主要通过压轨挤压，让榨汁机能充分榨出甘蔗汁液。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

In the process of breaking sugarcane and extracting juice, there are three methods: mechanical extraction, physical and chemical extraction and enzymatic extraction・But the limitations of physical and chemical extraction due to its adaptability and the generation of side effects and restrictions on the use of received・Mechanical extraction of fruit juice and vegetable juice is widely used in the pressing of tomatoes, pineapples, apples, citius and oranges・ Roller continuous juice press is one of the main machinery and equipment for mechanical juice extraction・Roller continuous juice press is a method of compressing volume to separate solid and liquid components of fruit and extract juice・ It is a kind of common food machinery that can provide juice pressing for medium-sized food enterprises and catering industry. The roller continuous Juicer designed in this paper introduces the design essentials, working principle and equipment composition of the squeezer based on compressed volume・ The design is mainly through roller extrusion, so that the juice extractor can fully extract sugarcane juice・ It is characterized by simple structure, small overall dimensions, juice with high efficiency, convenient operation, widely used in food factory.

Key words: mechanical extraction; pressing; roller continuous juicer; food machinery
