摘 要
本文主要对烘干机的设计,烘干机关键工序之一是烘干过程中即采取高温措施,又使新鲜食品内含物迅速地转化,使其水份充分挥发体积缩小。
烘干机技术依据导热介质不同可分为金属导热,蒸气导热,空气导热,采用不同的导热介质可烘干不同的原料。
滚筒烘干机是利用金属导热连续烘干的设备,原料由送料斗送入温度为200°
~280°C的滚筒内随着筒内导叶板的作用,产生滚筒翻滚抛扬和前进三种运动,在筒内热空气及筒壁,原料的接触下,表面和内细胞的水分迅速汽化。
本产品主要对零件进行烘干,但是也可以通过改变夹具对对其他一些物体进行烘干。属于一种多功能机器,
通过对烘干机的设计,使三年所学的机械专业知识在实践中加深了认识,并且相当于进行了一次全面性的复习。 [资料来源:http://THINK58.com]
Abstract
This text mainly to the design which dries a heat of machine, dry one of a heat of organization key work prefaces dries to namely adopt heat measure in the process, and then makes the fresh food contain a thing to convert quickly and make its water well vaporize a physical volume to contract.
The dryer technique can is divided into metals to transmit heat according to transmitting heat to lie a quality dissimilarity and the fume transmit heat, the air transmit heat, and adopting to differently transmit heat to lie quality can dry different raw material.
The roller dryer is in a row the equipments which makes use of metals to transmit heat to dry, raw material from send to anticipate Dou to send into the temperature as 200 °s
~Inside the roller of 280 ° Cs along with tube inside lead a leaf knothole function, the creation roller is vacillating to throw Yang and go forward three kinds of sport, at the hot air inside the tube and the tube wall, raw material of under the contact, surface with inside the humidity of cell quickly vaporizes.

This product mainly carries on dry to the electronics plank, but can also pass change tongs to as to it's he some objects carry on dry.Belong to a kind of multi-function machine,
Pass to the design which dries a heat of machine, make the machine professional knowledge that three years learn deepen understanding in the fulfillment, and equal to carried on to comprehensively review at a time.
