■ 應(yīng)用 ApplicAtion
◎ DWt系列帶式干燥機是成批生產(chǎn)用的連續(xù)式干燥設(shè)備，用于 透氣性較好的片狀、條狀、顆粒狀物料的干燥，對于脫水蔬菜、 中藥飲片等含水率高、而物料溫度不允許高的物料尤為合適；該 系列干燥機具有干燥速度快、蒸發(fā)強度高、產(chǎn)品質(zhì)量好的優(yōu)點， 對脫水濾餅類的膏狀物料，需經(jīng)造粒制成棒狀后亦可干燥。
◎ this machine is flowing and continuous type drying equipment firstly made by our company. the machine is used for drying the piece, tape and particle state materials with good ventilation. the machine is suitable for the materials, such as de-watering vegetable, herbal medicine of traditional Chinese medicine and others, for which the water content rate is high and the high temperature is not allowed. the machine owns the advantages, that its drying speed is fast, the evaporation strength is high and the product quality is good. the de-watering filtering cake state paste material, after the particle making or bar making, can be dried also.

■ 原理 principle
◎ 原理如圖所示，料斗中的物料由加料器（6）均勻的鋪在不銹鋼絲 網(wǎng)（4）上，由傳動電機帶動網(wǎng)帶在干燥箱內(nèi)勻速移動。干燥段由 若干單元組成，熱風(fēng)在兩個（或幾個）單元內(nèi)橫向循環(huán)，新鮮空氣 由風(fēng)機（1）進入，通過換熱器（3）加熱，熱空氣穿過物料層與物料 熱交換，進入下腔，然后流向下一單元，降溫后的熱空氣再經(jīng)換 熱器（3）進行二次加熱，熱空氣穿透網(wǎng)帶與物料再次熱交換，濕 熱空氣由排濕風(fēng)機（2）（5）排出，完成干燥，每臺干燥機單元數(shù)可 根據(jù)物料的特性、工藝要求選取。
◎ the materials are uniformly put on the mesh-belt by the material charger. the mesh- belt uses generally 12 - 60 mesh stainless steel wire net and it is drawn and moved inside the dryer by a transmission device. the dryer is composed of several units. For each unit, the hot air is circulated separay. In the first unit,air out from circutation air blower（5） pass through beside into low unit,after air is up and heated by steam heater（4）, be shared by seperater（3）, the air is spraied through mesh-belt in to top of machine.the drying process is hot air passes through the mesh-belt covered with a special moisture from the top to the bottom or from the bottom to the top,and this will complete the heat and mass transfer process.the air pipe of the top is conected with fan, one part of air is circulated, some exhausted gas is discharged with a special moisture eilmination blower,and other waste gas is controlled through an adjustment valve.the top and low circulation units can be freely equipped according to the users’ demand, the unit nomber can be selected according to the demand.
