As an advanced drying technology,spray freeze dryer is widely used in pharmaceutical,food processing,bioengineering and other industries,especially for processing heat-sensitive substances.In these fields,particle size has an important impact on the final quality and use effect of the product.Therefore,whether the particle size can be effectively controlled has become a key issue in the research and application of equipment.

Low temperature continuous spray dryer is a kind of equipment that uses spray technology to atomize liquid materials into tiny droplets and then quickly dry them at low temperature.During the drying process,the droplets exchange heat with hot air,so that the water in the droplets evaporates quickly,and finally a dry product is obtained.This drying method has the advantages of short drying time,high efficiency and good product quality.It is widely used in the fields of food industry,pharmaceutical industry and chemical industry.

As a highly efficient drying and granulating equipment,spray granulation dryer is widely used in pharmaceutical,chemical,food and other industries.However, during use,the problem of too fine particles sometimes occurs,which not only affects the quality of the product, but also may increase production costs.

After using a section of spray drying equipment, in order to ensure the normal use next time, the spray dryer needs to be cleaned and maintained regularly. There are three cleaning methods, namely chemical cleaning, dry cleaning and wet cleaning. You can choose different cleaning methods according to your own conditions and needs.

The spray dryer uses the method of spraying to spray the material into mist and loosen it in the hot air. The material and the hot air contact each other in the form of parallel flow, countercurrent or mixed flow, so that the water evaporates quickly to achieve the purpose of drying. Using the method of spray drying can save unit operations such as concentration, filtration, and destruction, and the drying time is short, and the product has good fluidity and instant solubility, so it is widely used in industries such as medicine.

The laboratory spray dryer has the characteristics of fast heat transfer, rapid water evaporation, and instant drying time. The quality of the product is good, and the solubility is also good. It can improve the dissolution rate of some preparations. It is widely used in food, pharmaceutical, chemical research, etc. multiple industries.

Spray granulation dryer is a kind of drying equipment that can produce products after fluidization, dust removal, atomization and solidification of materials to meet the particle size requirements. The process is generally that the air enters the bottom of the fluidized bed after being heated by a heater, and passes through the distribution plate to contact with the material to make the material fluidized. The mother liquid or binder is sent to the atomizing nozzle by the pressure-making equipment such as a pressure pump, and after atomization, it is coated on the surface of the fluidized particles or the particles are bonded to each other. After continuous fluidization, coating, and drying, the particles gradually grow After reaching the required particle size, it is discharged from the outlet of the fluidized bed. Widely used in chemical, pharmaceutical, food and other industries.

Spray dryers are widely used in various fields, and can be used in the chemical industry, such as battery raw materials, alkaline dyestuff pigments, dyestuff intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulphuric acid agents, amino acids, white carbon black, etc. It can be used in plastic resin, such as AB, ABS emulsion, urea-formaldehyde resin, phenolic resin, dense glue (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc. It can be used in food industry, such as fat-rich milk powder, aricin, cocoa milk powder, milk substitute powder, animal blood powder, egg white (yolk) whole egg powder, etc. Can be used in food and plants, such as oats, chicken juice, coffee, instant tea, seasoned spiced meat, protein, soybean, peanut protein, hydrolysate, etc. Can be used for sugars, e.g. corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc. Can be used for drying ceramic materials, such as alumina, tile materials, magnesium oxide, talcum powder, etc.

Centrifugal spray dryers have a high level of automation and can be used to dry solutions, emulsions, suspensions and even liquid materials with viscosity. Centrifugal spray dryers, which are used to dry certain liquid materials using centrifugal atomisers, are one of the most widely used dryers in industrial production today.
