一、工作原理与应用范围介绍 Introduction of Working Principle and Scope of Application
物料经均匀地铺放于（板式或网式）带上，由传动装置拖动在干燥机内作水平运动，热风穿过网带（或网板）与带上的物料进行转热传质，从而达到干燥目的。干燥机根据工艺及用户需要可设计为整体通热与若干独立热风循环单元形式，尾气由专门排湿风机排出，工作时热风由下往上或由上往下穿过铺在板式或网式带上的物料，加热干燥并带走水分。网带缓慢移动，运行速度可根据物料温度自由调节，干燥后的成品连续落入收料器中。上下循环单元根据用户需要可灵活配备，单元数量可根据需要选取。
主要适用于干燥小块的物料及纤维质以及透气性较好的片状、条状、颗粒状物料的干燥。对于脱水蔬菜、催化剂、中药饮片等含水率高、而物料又不允许高温烘烤，而且还要求保持物料外形等要求的物料尤为合适。
带式干燥机具体结构与形式需根据物料特性以及工艺要求，可选择单层带式、多层带式、平流带式、穿流带式、喷射带式。
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、特点 Characteristics
1.物料在带式干燥过程中受到的振动与冲击比较小，对物料成型的破坏性小，适用于干燥某些不允许碎裂的物料。
2.可以调节热空气量、加热温度、物料停留时间及加料速度来获得适合的干燥工艺与烘干效果。
3.设备配置灵活，可选配自动冲洗系统及物料冷却系统以及智能化控制操作系统。
4.可根据工艺及场地要求选择单层、多层、平流、穿流、喷射等多种形式来满足需求。
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 inligent 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.
