Category: Drying equipment series
Product Overview: The YPG series pressure spray (cooling) dryer uses a pressure atomizer to atomize the solution or slurry material into fine droplets with the help of the pressure of the diaphragm pump, so that the surface area is significantly increased, and it is fully heated by hot air. The exchange can be quickly dried (ten seconds to tens of seconds) to obtain powder or fine particle products.
product description
This unit is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow rate, and size of the nozzle hole of the feed liquid pump can be adjusted to obtain the required spherical particles in a certain size ratio.
working principle
The working process of this unit is that the material liquid is input through the diaphragm pump under high pressure, spraying mist-like droplets, and then descending in parallel with the hot air. Most of the powder particles are collected by the discharge port at the bottom of the tower, and the waste gas and its tiny powder are separated by the cyclone separator. , The exhaust gas is discharged by the exhaust fan, and the powder is collected by the pollination tube set at the lower end of the cyclone separator. The outlet of the fan can also be equipped with a secondary dust removal device, and the recovery rate is above 96-98%.
Performance characteristics
◎The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95%-98% of the water can be evaporated in an instant, and the drying time only needs ten seconds to tens of seconds, especially suitable For the drying of heat-sensitive materials.
◎All products are spherical particles with uniform particle size, good fluidity, good solubility, high product purity and good quality.
◎Wide range of application, according to the characteristics of the material, it can be dried with hot air or granulated with cold air, which has strong adaptability to the material.
◎Simple and stable operation, convenient control, easy to realize automatic operation.
Adapt to materials Spray-dried granules:
◎Chemical industry: There are catalysts, resins, synthetic detergents, oils, ammonium sulfate, dyes, dye intermediates, white carbon black, graphite, ammonium phosphate, etc.
◎Food: amino acids and analogues, seasonings, proteins, starches, dairy products, coffee extracts, fish meal, meat essence, etc.
◎Pharmaceuticals: Chinese patent medicines, pesticides, antibiotics, pharmaceutical granules, etc. ◎Ceramics: Magnesium oxide, porcelain clay, various metal oxides, dolomite, etc.
◎Spraying granulation: all kinds of fertilizer, alumina, ceramic powder, pharmaceutical, heavy metal superhard steel, chemical fertilizer, granular washing powder, Chinese patent medicine.
◎Spray cooling granulation: amino fatty acid, paraffin wax, glycerate, tallow, etc. It is often used in spray crystallization, spray concentration, and spray reaction.
