The PLG series disc continuous dryer is a conductive continuous drying equipment. Its structure and working principle determine that it has the characteristics of high thermal efficiency, low energy consumption, small footprint, simple configuration, convenient operation and control, and good operating environment. Widely applicable to drying operations in industries such as chemical, pharmaceutical, pesticide, food, feed, and agricultural and sideline product processing. Highly praised in practical applications across various industries.
This disc drying equipment can be divided into three types: atmospheric pressure, closed, and vacuum; There are four specifications: 1200, 1500, 2200, and 3000; A (carbon steel), B (stainless steel for the contact material part), and C are made of three materials (stainless steel for the steam pipeline, main shaft, and support, and stainless steel for the cylinder and top cover lining) on the basis of B, with a drying area of 4-180m2. There are hundreds of models of series products available, and supporting auxiliary equipment can be provided to meet the drying needs of users for various materials.
The wet material is continuously added to the upper layer of the drying disc of the dryer by the feeder, and the rake arm with rake blades rotates to continuously flip the material. The material crosses the surface of the drying disc along an exponential spiral, and the material on the small drying disc is transferred to the outer edge, where it falls to the outer edge of the large drying disc below. The material moves inward on the large drying tower and falls into the next layer of small drying disc from the middle discharge port. The drying plates of different sizes are arranged alternately up and down, allowing the material to flow continuously through the entire dryer. A hollow drying tray is filled with heating medium, which includes saturated steam, hot water, and thermal oil. The heating medium enters from one end of the drying tray and exits from the other end. The dried material falls from the last layer of the drying tray to the bottom of the shell, and is finally transferred by the rake blades to the discharge port for discharge. Moisture escapes from the material. The moisture in the vacuum disc dryer is discharged through the exhaust port located on the top cover, and the moisture is extracted by the vacuum pump located on the top cover. Dry materials discharged from the bottom layer can be directly packaged. By adding auxiliary equipment such as fin heaters, solvent recovery condensers, bag filters, dry material mixing wood structures, and induced draft fans, the drying production capacity can be improved. Drying paste like and heat sensitive materials can be easily recovered from solvents, and pyrolysis and reaction operations can be carried out.
(1) Easy regulation and strong applicability
The drying process can be completed smoothly by adjusting the thickness of the material layer, the spindle speed, the number of rake arms and the size of rake wikstrobe.
Each layer of drying disc can be separately passed into the hot medium or cold medium, heating or cooling the material, the material temperature control is accurate and easy.
The residence time of the material can be precisely adjusted.
The material flow is single, no backmixing phenomenon, uniform drying, stable quality, no need to mix.
(2) Simple and easy operation
The dryer is very simple to start and stop.
After the feed is stopped, the rake blade can quickly empty the material in the dryer after the material is transferred.
Through the special large-size view of the door mirror, the equipment can be carefully cleaned and observed.
(3) Low energy consumption
The material layer is very thin, the spindle speed is low, the system requires less power and less power consumption.
Conduction heat for drying, high thermal efficiency, low energy consumption.
(4) The operating environment is good, the solvent can be recovered, and the dust emission meets the requirements
Atmospheric pressure type: due to the low airflow speed in the equipment and the low temperature distribution in the equipment, the dust is difficult to float to the top of the equipment, so the exhaust gas discharged from the top temperature outlet almost does not contain dust.
Closed type: equipped with solvent recovery device, can easily recover the organic solvent in the wet gas. Solvent recovery device is simple, high recovery rate, for flammable, explosive, toxic and easily oxidized materials, nitrogen can be used as a wet gas for closed cycle, so that it is safe to operate. Especially suitable for the drying of flammable, explosive and toxic materials.
(5) Easy installation, small footprint
The dryer is delivered as a whole, transported as a whole, just need to be hoisted into place, and installation and positioning is very easy.
Due to the vertical layout of the drying tray layer and vertical installation, the drying area is large and the floor area is small.
