概述   Description

        沸腾干燥器，又称流化床，经过30年的使用、改进，目前在制药，化工，食品，粮食加工方面，越来越体现了它的重要作用。它是由空气过滤器，沸腾床主机、旋风分离器，布袋除尘器，高压离心通风机、操作台组成。由于干燥物料的性质不同，配套除尘设备时，可按需要而进行，可同时选择旋风分离器，布袋除尘器。也可选择其中的一种。一般来说，比重较大的物料只需选择旋风分离器。比重较轻的物料需配套布袋除尘器，并备有气力送料装置选择。本设备有连续型与间隙式两种操作方式。

Fluidizing dryer is also called fluid bed. Through operation and improvement over 30 years, it has play an active part in the fields of pharmaceutical, chemical, foodstuff, gain and so on industries. It consists of air filter, fluid bed, cyclone separator, dust collector, high-speed centrifugal fan, control cabinet and so on. Because of the difference of property from raw material, it is necessary to equip dust remover in accordance with practical needs. It may select cyclone separator and dust collector both or one of them. In general, cyclone separator can be selected if the raw material is larger and the dust collector may be selected if the raw material is light. Moreover, there is pneumatic feeding device for your selection. There are two kinds of operation for this machine, continuous and intermittent type.

应用   Application

        医药药品、化工原料、食品、粮食加工、饲料的干燥作业。如：原料药、压片颗粒、中药冲剂、保健食品、饮料 冲剂、玉米胚芽、饲料、塑料树脂、柠檬酸和其它粉粒状物料的干燥除湿。适用物料粒径一般为0.1～6mm ， 粒径为0.5～3mm。

Drying process of medicines, chemical raw material, foodstuff, grain processing, feed and so on. For example, raw medicine, tablet, Chinese medicine, foodstuff of health protection, drinks, feed, resin, citric acid and other powders. The suitable diameter of raw material is normally 0.1-0.6mm. The most applicable diameter of raw material will be 0.5-3mm.

原理   Principle

         洁净的热风经阀板分配进入床体内，从加料器进入的湿物料被热风形成沸腾状态。由于热风与物料广泛接触，增加了传热传质的过程，因此在较短时间内就可干燥。如用连续型，物料从床体的一头进入，经过几十秒至几分钟沸腾干燥，自动从床体另一头流出。本设备一般进行负压操作。
