Disc Paddle Dryer

Disc paddle dryer

FEATURES

Disc dryer as an indirect heating drying equipment

（1）High flexibility

1. The drying degree of materials can be adjusted according to the user's requirements, with a wide range of adjustment (full drying to semi drying can be adjusted at will);

2. It has a wide range of adaptability to the moisture content of materials, can withstand higher material load, and can ensure smooth operation even if the feed is uneven.

（2）Low operating costs

1. The cylinder of the dryer is a jacket type structure, the main shaft and disc are hollow, with steam circulation, the heat exchange area is very large, the structure of small body and large heat exchange surface is the guarantee of high efficiency, and the single shaft thrust free design is the guarantee of low power consumption;

2. The horizontal disc dryer has the characteristics of compact structure, small surface area and good airtightness. The dryer has less heat transfer to the environment and greatly reduces the heat loss;

3. Semi drying does not need dry material back mixing, saving energy consumption of material repeated cooling and heating;

（3）Safety and stability

1. The design of drying temperature is low, so it is not easy to produce a lot of insoluble gas;

2. The evaporation rate of the dryer is high, and the inertia of the system depends on the humidity;

3. When the water content of sludge fluctuates, the system has a wide range of process adjustment

WORKING PRINCIPLE

disc paddle dryer is mainly composed of stator (shell), rotor (turntable) and driving device. The central shaft of the rotor is the load-bearing part of the drying turntable. It is a hollow shaft on which all turntables are welded. The disk dryer is driven and stirred by the edge of the rotary table. The wet material is evenly and slowly transported through the whole dryer and dried by the thermal contact with the rotary table. During the drying process, the hot steam condenses on the inner wall of the rotary table cavity to form condensed water. The condensed water is led into the central pipe through a pipe and is led out of the dryer through an outlet tank. A scraper is arranged between each two turntables, and the scraper is fixed on the shell (stator). The scraper can loosen the material between discs and make the waste steam leave the sludge quickly.
