Description
(Potassium Fluoride Powder) Spray Dryer is the most widely used process in liquid shaping technology. It is suitable for producing powder and granules solid products from solution, emulsion, soliquoid, and pumpable paste materials. Therefore, when the particle size, final moisture, bulk density and granules shape meet the accurate standard, centrifugal spray drying is a ideal drying process.
Working Principle
Liquid material is atomized through a special pressure nozzle with a high-pressure pump. Hot air enters the dryer after being adjusted by an air distributor. The material and hot air is mixed in the dryer, rapidly carries on heat and mass transfer. Powder or granular products are produced in a very short time. Products with larger particles size are discharged from the bottom of the dryer, smaller particles enter the cyclone with hot air. The exhaust gas is discharged into the air after dust removal in a scrubber. The dryers can be divided into high, middle and low-pressure spray dryers according to different pressures of atomization, while taking into account different flow fields, they are divided into co-current, fountain mode and counter-current spray dryers.
Performance characteristics
1. 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 instantly, and the drying time is only a few seconds, which is especially suitable for the drying of heat-sensitive materials.
2. The product has good uniformity, fluidity and solubility, high purity and good quality.
3. Simplified production process and convenient operation and control. For liquids with a moisture content of 40-60% (up to 90% for special materials), the liquid can be dried into powder products at one time, without crushing and screening after drying, reducing production procedures and improving product purity. The product particle size, bulk density and water content can be adjusted by changing the operating conditions within a certain range, and the control and management are very convenient.
Applicable Materials
Potassium Fluoride Powder
Potassium fluoride is the chemical compound with the formula KF. After hydrogen fluoride, KF is the primary source of the fluoride ion for applications in manufacturing and in chemistry. It is an alkali halide and occurs naturally as the rare mineral carobbiite. Solutions of KF will etch glass due to the formation of soluble fluorosilicates, although HF is more effective.
Chemical industry: sodium fluoride (potassium), basic dyes and pigments, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid, amino acids, white carbon black, etc.
Plastic resin: AB, ABS emulsion, urinary formaldehyde resin, phenolic resin, dense rubber (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc.
Food industry: fat-rich milk powder, gluten, cocoa milk powder, milk substitute powder, blood hunting powder, egg white (yellow), etc.
Food and plants: oats, chicken juice, coffee, instant tea, flavored meat, protein, soybean, peanut protein, hydrolysate, etc.
Sugars: corn syrup, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.
