KimHello, I got the goods this morning. Very good quality. Thank you so much for doing business with me and you are so patient and clear on explanation.
Johnny CisnerosOne of the great positives in working with you and the company you work for is your response back to emails and your professionalism.

Polyphenol PLG Series Vacuum Continuous Plate Drying machine (Vacuum continuous plate dryer) for pharmaceutical industry
PLG-P continuous Plate Pharmaceutical Conductive style drying machine (continuous Plate dryer ) (continuous Plate drying Equipment )is a kind of high efficiency conducting and continuous drying equipment. Its unique structure and operating principle provide advantages of high heat efficiency, low energy consumption, less occupying area, simple configuration, easy operation and control as well as good operating environment etc. It is widely used in drying process in the fields of chemical, pharmaceuticals, agricultural chemicals, foodstuff, fodder, process of agricultural and by-products etc., and is well received by various industries. Now there are three big categories, normal pressure, closed and vacuum styles and four specifications of 1200, 1500, 2200 and 2500; and three kinds of constructions A (carbon steel), B(stainless steel for contact parts) and C (on the basis of B to add stainless steel for steam pipes, main shaft and support, and stainless steel linings for cylinder body and top cover). With a drying area of 4 to 180 square meters, now we have hundreds of models of series products and various kinds of auxiliary devices available to meet requirements of various products.
It is an innovation horizontal batch-type vacuum dryer . The moister of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump.
Wet materials are fed continuously to the top drying layer in the dryer. They will be turned and stirred continuously by harrows when the harrow's arm rotates, the material flows through the surface of the drying plate along the exponential helical line. On the small drying plate the material will be moved to its exterior edge and drop down to the exterior edge of the large drying plate underneath, and will then 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 dryer continuously. The heating media, which could be saturated steam, hot water or thermal oil will be led into hollow drying plates from one end to other end of the dryer. The dried product will drop from the last layer of the drying plate to the bottom layer of the smell body, and will be moved by harrows to the discharge port. The moisture exhausts from materials and will be removed from the moist discharge port on the top cover, or sucked out by the vacuum pump on the top cover for vacuum-type plate dryer. The dried product discharged from the bottom layer can be packed directly. The drying capability can be raised up if equipped with supplementary devices such as finned heater, condenser for solvent recovery, bag dust filter, return and mix mechanism for dried materials and suction fan etc. solvent in those paste state and heat sensitive materials can be easily recovered, and thermal decomposition and reaction can be also carried out.
80 square meters, now we have hundreds of models of series products and various kinds of auxiliary devices available to meet requirements of various products.

(1) Easy to adjust and control, good applicability.
- The drying efficiency can be improved by adjusting the thickness of material layer, rotary speed of main shaft, quantity of harrow arm, shape and size harrow plates.
- Each drying layer can input hot medium or cool medium individually for heating or cooling. The temperature control is accurate and easy to adjust.
- The residence time of materials can be adjusted accurately.
- Single material flowing direction to prevent material return and mixing. The drying process is uniform and the quality stable, no re-mixing is required.
(2) Easy to operate
- Simple operation for turn on and turn off.
- After material feeding is stopped, the remaining material inside of the machine can be easily discharged out by the harrows.
- You can clean and observe inside from the large-scale viewing window.
(3) Low energy consumption
- The material layer is thin and the rotary speed of main shaft is low so it required low power and electricity consumption.
- The material is dried by conducting heat so it has high heating efficiency.
(4) Good operation environment
- Normal pressure type:
The speed of air flow inside of the machine is low and the humidity is high in upper end and low in bottom end so the dust can’t float to the top which keeps no dust in the exhausted air.
- Closed type:
The machine is equipped with solvent recovery device which can recover organic solvent easily from the wet air. The solvent recovery device has a simple structure and high recovery rate. For the flammable, explosive and poisonous materials, the nitrogen can be used as medium for closed circulation and keeps a safe working condition.
- Vacuum type:
The plate dryer is operating under vacuum condition and it is particularly suitable for drying heat sensitive materials.
(5) Easy installation
- The dryer is delivered in a complete piece so it is quite easy to install and fix at site.
- The disc plates are being arranged by layers and it will be installed vertically so it takes a small occupying area from the workshop.
