Introduction
PLG Series Continuous tray dryer is a high-efficiency conducting and continuous drying equipment. Its unique structure and operating principle determine that it has advantages of high heat efficiency, low energy consumption, small occupied area, simple configuration, easy operation, and control as well as good operating environment and etc. It can be widely used in the drying processes in the fields of chemical, pharmaceuticals, agricultural, foodstuff, feed, and other industries.
There are three major types: normal pressure type, closed type, and vacuum type; and four major models: 1200, 1500, 2200, and 3000; and three kinds of material grades, A(carbon steel), B(use stainless steel for the material contacted area), and C(use stainless steel for the material contacted area, steam pipes, main shaft and supports, and linings for cylinder body and top cover). The drying area of the dryer is 4 to 180 m2.
We have produced hundreds of models with auxiliary devices which are available to meet the requirements of all customers.
Working Principle
The wet material is fed continuously to the first drying layer on the top of the dryer. It will be turned and stirred by rakes when the rake arm rotates and drop down to the outer edge of the large drying plate along the exponential helical line.
The material will be moved from the small drying plate to its outer edge and dropped down to the outer edge of the large drying plate underneath. Both small and large drying plates are arranged alternately so the materials can go through the dryer continuously.
The heat medium can be saturated steam, hot water, or thermal oil. The heat will be led into hollow drying plates from one end and come out from the other end.
The dried materials will drop from the last layer of the drying plate to the bottom of the dryer and then move by rakes to the discharge outlet.
The material moisture will be removed from the exhaust outlet on the top cover. For the vacuum-type plate dryer, the moisture will be sucked out by the vacuum pump on the top cover.
The dried materials will be discharged from the bottom layer. The drying capability can be improved if the dryer is equipped with supplementary devices such as a finned heater, condenser for solvent retrieval, bag dust remover, return and mix mechanism, draft fan, and etc.

Feature
(1) Easy to adjust and control, good applicability.
- The drying efficiency can be improved by adjusting the thickness of the material layer, rotary speed of the main shaft, the quantity of harrow arm, shape, and size of 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 the 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 airflow inside of the machine is low and the humidity is high in the upper end and low in the 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 a solvent recovery device that can recover organic solvent easily from the wet air. The solvent recovery device has a simple structure and a high recovery rate. For the flammable, explosive, and poisonous materials, the nitrogen can be used as a medium for closed circulation and keeps a safe working condition.
- Vacuum type:
The tray dryer is operating under vacuum conditions 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 the site.
- The disc plates are being arranged by layers and they will be installed vertically so it takes a small occupying area from the workshop.
Process conditions
Installation and Commissioning and Training:
1. Buyers arrange installation and debugging by themselves under a manual book from the supplier.
2. If the buyer requires engineers from the seller's party, the buyer should arrange the following items:
(A)Within 30 days after the machines are delivered to the buyer's factory, the buyer shall inform the seller to arrange engineers to the buyer's factory for installation, commissioning, test, and training machine operators.
(B)The buyer should provide the engineers(1-2 person) the boarding and lodging, transportation during the engineer's stay in the buyer's country, and round trip air ticket and visa fee for the engineers. Besides, the buyer should pay the money as salary for one engineer per day.
