Pneumatic Dryer

Working Principle: It adoptsan advanced pulsed heat transfer method, changing the relative velocity between material and heat medium so as to enhance the heat & mass transfer process. The material first enters a smaller pipe, where the air current flows at a high velocity and causes the granules to move at an accelerated speed. At the end of the accelerated movement, the pipe expands suddenly. Because of inertia, the velocity of granules is greater than that of the air current. In the moving process, because of the air current resistance, the velocity of granules decreases. Then the pipe diameter is reduced suddenly, the granules are speeded ...

Chained-Plate Dryer

Applications: The chained plate dryer is widely applied in drying the granulated, powdered or stripped materials such as Chinese herbs, sea food, feed, staple or chemical products. This equipment is generally used for grain, cotton, food, vegetable, beverage, charcoal, pigment or chemical industry. Product Introduction: The chained-plate dryer includes insulation case, in-feeding hopper, out-feeding hopper, conveying system and hot air circulating drying system consisting of air heater, ventilator, circulating air duct, inlet air duct, off-gas vent, air heat-exchanger. The air heater is equipped outside of the insulation case to supply heat to the drying system. The chained plate is g...

Large-scale Continuously-Conveying Dryer

Applications: It can be widely used in drying board-shaped materials in fields of new-generation building materials, environmental protection, energy and etc. such as paper-coated gypsum-board, gypsum-board for decoration, rockwool sound-absorbing board, Eternite board and all kinds of fiber boards formed by means of extrusion or compaction process. Product Introduction: Based on horizontally-drying technology introduced from foreign country (Germany) and in combination with traditional longitudinally-drying technology, we have developed this large-scale continuously-conveying dryer (unit), which It can be widely used in drying board-shaped materials in fields of new-generation buildin...

Mini Spray Dryer

Working Principle: Spray drying involves the atomization of droplets in a spray from a liquid feedstock and the droplets contact with hot air in a drying chamber. The sprays are produced by two-fluid nozzle atomizers. Evaporation of moisture from the droplets and formation of dry powder are proceededon controlled temperature and airflow conditions. Powder is discharged from the drying chamber and mostly is collected by the cyclone separator. Characteristics: 1. Operating conditions and dryer design are determined according to the drying characteristics of the products and powder specifications. ...

Mini Fluidized Bed Dryer

Working Principle: Preheated air is passed into product layer under controlled velocity after being uniformed by the distributor so asto create an fluidized state. The raw material is fed into the bed. Dehydration process can take place on at very good heat & mass transfer condition. The exhaust air is cleaned by cyclone. Material to be dried: This dryer is mainly used for drying of powder or particle materials in pharmaceutical, food and chemical industry. The examples of materials dried in such dryers are powdered coal, fine ore, sand, ammonium sulfate, ammonium chloride, anhydrous sodium sulfite, ta...
