1Purpose and Characteristics
This machine is medepartmentSpecially targeting Chinese medicinal herbsRaw materialsEfficient drying equipment developed for production with drying characteristics. Compared to ordinary mesh belt dryersmaterialIt has stronger pertinence and advantages in terms of drying.materialDue to the wide variety of types, materials have different characteristics and process requirements during drying. Therefore, when selecting, the equipment structure, configuration, and drying method should be adjusted reasonably according to the properties of the materials to adapt to their properties and user requirements.
in the light ofMany pharmaceutical factories haveChinese medicinal herbsRaw materialsThe requirement for product drying is to adapt to the physical properties of multiple types of materials at different drying stages, combine them into a reasonable drying process, obtain the best product quality, and effectively save energy.
Working principle: (see)Structural schematicThe material in the hopper is evenly (or manually) spread on the mesh belt by the feeder. The mesh belt adopts stainless steel mesh (the mesh size is determined by the material properties). Dragged by a continuously variable transmission device, the dryer moves at a constant speed. The dryer consists of several units, with forced air intake, forced circulation, and forced dehumidification for cold and hot air. The number of units can be flexibly configured according to user needs, and it has the advantages of high thermal efficiency and low equipment energy consumption.
2Technical Description
The complete set of equipment includesComposed of box body, conveying system, circulating fan, heating system, exhaust system, electrical control system, auxiliary equipment, etc.
The box adopts an insulation frame structure.The inner wall is made of stainless steelSUS304δ1.2mm, The outer wall is made of stainless steel SUS304 δ 1.2mm, the frame is welded with carbon steel (Q235-B) profiles, and the insulation material is ultra-fineAluminum silicateCotton.
Both sides of the box are equipped with maintenance doors and cleaning ports for easy maintenance and cleaning of the equipment. In order to ensure uniform drying of materials, a flow guide and air distribution device is designed inside the box
The conveying system is powered by a variable frequency reduction motor、Conveyor Chain、Conveyor belt、Mesh belt support rod, baffleDrive chain wheel、transmission shaft、Composition of tensioning device, etcAmong themThe conveyor belt adopts a balanced conveyor belt (including support rods)And the baffle).
Circulating fan adoptscentrifugalFanThe fan adoptsUniversal typeEasy to maintain and replace.
Heating adoptsstainless steelFin typesteamHeat exchanger, temperature control adoptselectromagnetismValve.
The exhaust system is used to remove the exhaust gas generated during drying, and the exhaust gas generated by each unit is collected and discharged outdoors.
The mesh belt transmission adopts frequency conversion speed control to ensure the safe operation of the equipment. When a malfunction occurs, safety protection measures are automatically taken on the control. Simultaneously sound and light an alarm.Net belt running speedcanAccording to the dry humidity of the material、Material auxiliary equipment thickness and drying temperatureenterPerform adjustment,Final material dehydration and operationspeedDryingtemperature、materiallayThe thickness is directly related.
The equipment is equipped with a feeding machine. The feeding machine is made of stainless steel mesh beltfunctionSynchronize the running speed with the running speed of the mesh belt
The equipment is equipped with a single vertical control cabinet,canusePLC program control+Color human-machine interface touch screenDisplay,In addition to relevant electrical components such as contactors and circuit breakers, the control box is also equipped with thermal protection and phase sequence protection devices.equipmentAutomatic temperature adjustment and control,Variable frequency speed regulation,Automatic forced dehumidification, equipment workingExcept for manual feedingallbyautomaticworkAnd implement three-level password protection.
