　　　連續(xù)式顆粒烘干機(jī)是一種對(duì)物料進(jìn)行連續(xù)烘干的自動(dòng)化設(shè)備，廣泛地使用在糧食烘干、顆粒狀物料烘干上。我國(guó)是糧食生產(chǎn)大國(guó)，但糧食的品質(zhì)并不是很好。糧食的儲(chǔ)存是關(guān)系到糧食品質(zhì)的一個(gè)重要環(huán)節(jié)，烘干機(jī)的烘干性能是決定烘干品質(zhì)的重要因素。烘干機(jī)可以將糧食烘干到有利于糧食儲(chǔ)存的水分含量，對(duì)糧食的儲(chǔ)存起到了至關(guān)重要的作用。本次我設(shè)計(jì)的烘干機(jī)為連續(xù)式烘干機(jī)，主傳動(dòng)系統(tǒng)、烘干系統(tǒng)均采用電機(jī)為動(dòng)力裝置。不同于市面上常見的滾筒式烘干機(jī)，相對(duì)于其它形式的烘干機(jī)機(jī)，連續(xù)式顆粒烘干機(jī)具有穩(wěn)定性好，烘干效率高，試用范圍廣，易于控制，使用壽命長(zhǎng)等優(yōu)點(diǎn)，更重要的是連續(xù)式顆粒烘干機(jī)本身造價(jià)低廉，性價(jià)比高，便于今后在市場(chǎng)上的推廣和應(yīng)用。

Title    Continuous grain dryer Host Design                      
                                                           

Abstract
Continuous grain dryer is a continuous drying of the material of automation equipment, it is Widely used in grain drying, drying the granular material. China is a major grain-producing country, but the quality of food is not good. Grain storage is related to an important part of food quality and drying machine drying performance is an important factor in the decision drying quality. Dryer can dry food to help the moisture content of grain storage, food storage played a crucial role. The dryer I designed for the continuous dryer, the main transmission system, drying system, motor-powered devices are used. Unlike the common market tumble dryer, compared to other forms of dryer machine, continuous grain dryer with good stability, high efficiency drying, try a wide range of easy to control, and long life more important is the continuous grain dryer itself is low cost, cost-effective, easy in the future in the market promotion and application.
