Yesterday, this type PGC Hot-plate dryer shipped out from our company，today, I show it here, only want to express its knowledge again.
Personally, I like its structure, the round shape, its accounts for that can lay out neatly and tidily, donot have many pipes, let person have a good feeling, also can easy to operate.
The above only my mind, from the appearance, now we start from the principle、feature、application to relieve the knowledge of PGC type hot-plate dryer. First, I interpret the name, in the beginning, its name “PGC plate dryer”, don’t have “hot” ,why we change it , and add a “hot”, that because “hot” can easier express its structure and principle.
Step one: Principle:
Wet materials are fed continuously to the first drying layer on the top of dryer. Materials will be turned and stirred by rakes when the rake arm rotates and flow through the surface of drying plate along the exponential helical line. On the small drying plate, materials will be moved to its outer edge and drop down to the outer edge of the large drying plate underneath, then will be moved inward and drop down from its central hole to the small drying plate on the next layer. Both small and large drying plates are arranged alternately so as materials can go through the whole drier continuously. The heating medium, which could be in forms of saturated steam, hot water or heat conducting oil, will be led into hollow drying plates from one port to the other port of drier. Dried material will drop from the last layer of drying plate to the bottom layer of the shell body, and will be moved by rakes to discharging port. The moisture will be removed from the moist discharging port on top of cover, or sucked out by the vacuum pump on the top cover for vacuum-type plate drier. The dried materials discharged from the bottom layer can be packed directly. Drying capability could be raised up if equipped with supplementary devices such as fin drier, condenser, bag filter, exhaust fan etc.
Step two: Feature
1. Easy in regulation and control, strong adaptability
2. Easy and simple operation
3. Low energy consumption
4. Good operation environment, solvent can be retrieved and dust powder discharge can meet requirement
5. Drying efficiency is high
Step three: Application
It is especially for drying and cooling powder materials like medicine, agriculture medicine, chemical industry, foodstuff, feedstuff and so on.
Organic chemical industry:
Inorganic chemical industry:
Medicine, food:
Feed, fertilizer:
