Food powder continuous plate dryer Disc dryer machine

Description of PLG Continuous Disc Dryer:

PLG Continuous Plate Dryer is appropriate for drying, calcining, pyrolysis, cooling, reaction and sublimation in the chemical, pharmaceutical, new energy, pesticide, food and agricultural industries.

Wet materials are continuously fed into the first layer drying plate on the top of the dryer. They will be turned and stirred by the rakes whose arms make rotational motion. The materials flow through the surface of the drying plate along the index spiral line. On the small plate the materials will move to the outer edge and drop down to the large drying plate. On the big one they will move inward and drop to the small plate on the next layer from the central hole. Both small and large drying plates are arranged alternately so that the materials can get through the whole continuous plate dryer. The heating media will be led into the hollow drying plate. The heating media includes saturated steam, hot water and conduction oil, and it will enter from one end and derive from the other end. The dried materials will drop from the last layer of the drying plate to the bottom layer of the shell. Finally, they will be transferred to the discharge port by the rakes. The moisture escapes from materials and will be expelled from the wet discharge port on the top cover. The moisture of vacuum type Drying Machine will be drawn out by the vacuum pump. Drying pasty and heat sensitive materials, this continuous plate dryer can recover the solvent and conduct pyrolysis and reaction operation.

Features of PLG continuous Disc Dryer:

(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.
