一、工作原理與應用范圍介紹 Introduction of Working Principle and Scope of Application

物料經均勻地鋪放于（板式或網式）帶上，由傳動裝置拖動在干燥機內作水平運動，熱風穿過網帶（或網板）與帶上的物料進行轉熱傳質，從而達到干燥目的。干燥機根據工藝及用戶需要可設計為整體通熱與若干獨立熱風循環單元形式，尾氣由專門排濕風機排出，工作時熱風由下往上或由上往下穿過鋪在板式或網式帶上的物料，加熱干燥并帶走水分。網帶緩慢移動，運行速度可根據物料溫度自由調節，干燥后的成品連續落入收料器中。上下循環單元根據用戶需要可靈活配備，單元數量可根據需要選取。

主要適用于干燥小塊的物料及纖維質以及透氣性較好的片狀、條狀、顆粒狀物料的干燥。對于脫水蔬菜、催化劑、中藥飲片等含水率高、而物料又不允許高溫烘烤，而且還要求保持物料外形等要求的物料尤為合適。

帶式干燥機具體結構與形式需根據物料特性以及工藝要求，可選擇單層帶式、多層帶式、平流帶式、穿流帶式、噴射帶式。

    The materials are evenly placed on the (plate or net type) belt and in horizontal movement in the drier due to the dragging of transmission gear. When the hot air passes through the net belt (or net plate), it engages in heat and mass transfer with the materials on the belt, achieving the purpose of drying. The dyer can be designed into an integral hot ventilation form or a form consisting of several independent hot air circulating units depending on the process and user demands. The tail gas is discharged through a dedicated moisture removal fan. In operation, the hot air passes through the materials laid on the plate or net type belt from bottom to top or from top to bottom for drying and taking away the moisture. The net belt moves slowly. The speed can be adjusted according to the temperature of materials. The dried finished products will fall into the receiver. The up and down circulating units can be configured flexibly according to user demands and the quantity of unit can be determined as required. 

    It is mainly applicable to the drying of small materials, fibrous materials and flake-like, strip-shaped and granular materials with good air permeability, and particularly suitable for the materials with a high content of moisture which cannot withstａnd high temperature baking and are required to maintain their dimensions, etc. including dehydrated vegetables, catalysts, Traditional Chinese Medicine decoction pieces, etc.

    According to the characteristics of materials and technological requirements, the specific belt-type drying structure and form can be single layer belt type, multiple-layer belt type, laminar-flow belt type, cross-flow belt type, and spraying belt type.

二、特點  Characteristics

1.物料在帶式干燥過程中受到的振動與沖擊比較小，對物料成型的破壞性小，適用于干燥某些不允許碎裂的物料。

2.可以調節熱空氣量、加熱溫度、物料停留時間及加料速度來獲得適合的干燥工藝與烘干效果。

3.設備配置靈活，可選配自動沖洗系統及物料冷卻系統以及智能化控制操作系統。

4.可根據工藝及場地要求選擇單層、多層、平流、穿流、噴射等多種形式來滿足需求。

1. The vibration and shock against materials in belt type drying are small and have little destructive effects on the material forming. It is applicable to drying of the materials which should not be crushed.

2.   The optimal drying process and effects can be obtained through adjusting the hot air amount, heating temperature, stay time of materials and feed speed.

3.    The equipment can be configured flexibly. Automatic flushing system, material cooling system and intelligent control operation system can be used.

4.    Single layer belt type, multiple-layer belt type, laminar-flow belt type, cross-flow belt type, and spraying belt type can be selected according to process and site requirements to satisfy requirements.
