工作原理
＊ 工作原理如圖所示，料斗中的物料由加料器均勻鋪在網帶上，網帶采用12一60目不銹鋼絲網，由傳動裝置拖動在干燥機內移動。干燥機由若干單元組成，每一單元熱風獨立循環(huán)，其中部分尾氣由專門排濕風機4排出，每一單元排出廢氣量均有調節(jié)閥控制。在上循環(huán)單元中，循環(huán)風機5出來的風由側面風道進入單元下腔，氣流向上通過加熱器7加熱，經分配器6分配后，成噴射流吹向網帶，穿過物料后進入上腔。干燥過程是熱氣流穿過物料層，完成熱量與質量傳遞的過程。上腔由風管與風同入口相連，大部分氣體循環(huán)，一部分溫度較低含濕量較大的氣體作為廢氣經排濕管、調節(jié)閥、排濕風機排出。下循環(huán)單元中，循環(huán)風機出來的風*入上腔，向下經換熱器加熱，穿過物料層進入下腔，下腔由側風道及回風管與風機入口相連，大部分氣體循環(huán)，一部分排出。上、下循環(huán)單元根據用戶需要可靈活配備，單元數量也可根據需要選取。

＊ 用于脫水蔬菜，一般使用三臺設備串連使用，形成初干段，中間段及終干段。在初干段中，由干物料含水量高，透氣性差，故應采用較小的鋪推高的干燥溫度。初干段中，干燥氣體溫度可達120℃以上。終干段內物料停留時間是初干段的3-6倍，鋪料厚度是初干段的2-4倍。對干物料溫度不超過60℃的要求，可采用80℃左右的干燥氣體。采用多段組合能更好地發(fā)揮帶式干燥機的性能，且干燥更均勻。

Working Principle
＊ As showed in the drawing,materials inside the hopper is spread uniformly by the feeder onto the mesh belt made of 12-60 eye stainless steel and moved inside the drier by driving devices. Drier is composed by a few units in which hot air circulates separay and waste air is exhausted by adjustable special fan.During the upper circulation,circulated air enters the lower chamber of the unit and the air flow is heated and distributed to mesh belt in the form of spraying flow before it enters upper chamber through the belt materials.Drying process is the duration of hot air flowing through material layer, where heat and quality is transmitted.upper chamber is connected by air pipe with fan inlet,in which,most part of air circulates except those with low temperature and high humidity which is drained through humidity exhaust.regulation valve and exhaust fan,In the low circulation unit,circulated air enters upper chamber first,heated by exchanger when down-streams through material layer to the lower chamber which is connected with fan inlet by side air pipes and return air pipes,most part of air circulates with little be drained. Moreover,each unit can be completed freely according to user′s request.

＊ If used for dewatering vegetables.Serial 3 sets is normally adopted to form initial,middle and final drying section,among which,initial section takes thinner spreading thickness,speedy runing and higher drying temperature which can reach 120-hold time in the final section will be 3 ~ 6 time of initial one,spreading thickness will be 2-4 times,normally drying air around 80℃ is used for materials who require a temperature not over 60℃.All in all,multy-section composition will put the properties of belt drier into full play.
