A pressure spray dryer is a device that can simultaneously perform drying and granulation. According to the process requirements, the pressure, flow rate and orifice size of the liquid pump can be adjusted to obtain the desired spherical particles in a certain proportion. Suitable for chemical, food, pharmaceutical, ceramic, spray granulation, fertilizer, spray cooling granulation and other industries. The working process is that the liquid feeds through the high pressure input of the diaphragm pump, and sprays the mist droplets, and then flows down with the hot air. Most of the powder particles are collected by the bottom discharge port, and the exhaust gas and its fine powder are separated by the cyclone separator. The exhaust gas is discharged by the exhaust fan, and the powder is collected by the pollinator located at the lower end of the cyclone. The fan outlet can also be equipped with a secondary dust removal device, and the recovery rate is above 96-98%. The material of the tower body, the pipe and the separator which are in contact with the material are all made of SUS304. There is sufficient insulation between the inside of the tower body and the outer casing. The filling material is ultra-fine glass wool. The tower body is provided with an observation door, a sight glass, a light source and a control instrument, and is controlled and displayed by an electric control console. The heat source device adopts steam heating or electric heater, and has the advantages of convenient operation, quick start, compact structure, clean and clean hot air and the like. In addition, a control and adjustment device for the electric heater is installed in the electric control cabinet to make the inlet temperature steplessly adjusted. For the power shortage area, steam heating or coal burning, fuel hot air furnace, etc. may be used to replace the electric heating device partially or completely.
Features of the pressure spray dryer :
(1), the drying speed is fast, the surface area of ​​the liquid is greatly increased after atomization, and in the hot air flow, 95-98% of the water can be evaporated instantaneously, and the drying time takes only ten seconds to several tens of seconds, especially Suitable for drying heat sensitive materials.
(2) The obtained product is spherical particles with uniform particle size, good fluidity, good solubility, high purity and good quality.
(3) Wide range of use, according to the characteristics of the material, it can be dried by hot air or cold air, which has strong adaptability to materials.
(4) Simple and stable operation, convenient control and easy to realize automatic operation.
Centrifugal spray dryer application:
The so-called centrifugal spray dryer uses a centrifugal atomizer to dry certain liquid materials. It is one of the widely used dryers in industrial production. Spray drying is a widely used process in the liquid process forming and drying industry. Zui is suitable for the production of powdery, granular products in solutions, emulsions, suspensions and pumpable lake-like liquid materials. Therefore, spray drying is an ideal process when particle size distribution, residual moisture content, bulk density and particle shape meet precise standards.
Features of the centrifugal spray dryer :
(1) The drying speed is fast, the surface area of ​​the liquid is greatly increased after atomization, and in the hot air flow, 95%-98% of the water can be evaporated in an instant. It takes only 5-15 seconds to complete the drying time and has the characteristics of instantaneous drying.
(2), special air distribution device, reduce the resistance of the equipment, and effectively provide the treatment of the dryer.
(3), the production process is simplified, suitable for continuous control of production, liquid with 40-90% moisture content, once dry into powder, reduce crushing, screening and other processes to improve product purity.
(4), the material completes the drying process in a short time, is suitable for the drying of heat sensitive materials, and can maintain the color, fragrance and taste of the materials.
(5), product dispersibility, fluidity, solubility, product particle size, looseness, water in a certain range of adjustable airflow spray dryer application:
The airflow spray dryer is highly automated and flexible (it can control the particle size of the finished product). It is especially suitable for solutions, emulsions, pastes, suspensions and even viscous materials. Particularly suitable for medium or experimental scale drying of materials.
Airflow spray dryer features:
(1) The drying time only takes 10 to 30 seconds. Due to the short drying time, the product can maintain a uniform fine particle shape (the product has good dispersibility, fluidity and solubility).
(2), flexible control. For the product's grain, bulk density, moisture, product properties (excluding dust, fluidity, wettability, instant solubility), the operating conditions can be adjusted within a certain range to adjust and control.
(3) For paste materials with large viscosity, the paste material works very well.
(4) The quality of the finished product is good. Can retain the color, aroma, taste, and other biological activities of the material; the moisture content of the Zui final product;
(5), the nozzle structure is simple (the cost of the atomization system is only 1/3 of the pressure type, 1/5 of the centrifugal type), the possibility of clogging is small, the one-time input cost is low, and the later use cost is also low.
