Spray drying is the most widely used process in the liquid process forming and drying industry. It is most suitable for the production of powdery, granular solid products from solutions, emulsions, suspensions and paste liquid materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet exact standards. Based on its technology, the small spray dryer has made deeper optimization and better adaptability.
First, the characteristics of small spray dryer
1 The production process is simplified, suitable for continuous control of production, liquid with 40-90% moisture content, drying to powder at one time, reducing crushing, screening and other processes to improve product purity. 2 Special air separation device reduces equipment resistance and effectively provides The treatment of the dryer is set.
3 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 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.
4 Product dispersibility, fluidity, solubility, product size, looseness, water can be adjusted within a certain range
5 The material completes the drying process in a short time, adapts to the drying of heat sensitive materials, and can maintain the color, fragrance and taste of the materials.
Second, small spray dryer manufacturers product range
1 Food industry: condensed milk powder, scorpion, cocoa milk powder, emulsion, pig blood powder, egg white (yellow), etc.
2 Plastic resin: AB, ABS emulsion, urine aldehyde resin, phenolic resin, dense rubber (urea) formaldehyde resin, polyethylene, polyvinyl fluoride, etc. 3 Sugar: corn syrup, corn starch, glucose, pectin, maltose, sorbus Potassium acid, etc.
4 food and plants: oats, chicken juice, coffee, instant tea, flavored meat, protein, soybeans, peanut protein, hydrolysate, etc.
5 Chemical industry: sodium fluoride (potassium), basic dyes, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid agents, amino acids, silica, etc. 6 Ceramics: Alumina, ceramic tile materials, magnesium oxide , talcum powder, etc.
Third, the working principle of small spray dryer
The centrifugal spray dryer works by passing air through the filter and heater into the air distributor at the top of the centrifugal spray dryer, and the hot air enters the dryer in a spiral shape. The liquid is pumped from the liquid tank to the centrifugal atomizer at the top of the dryer through the filter, so that the liquid is sprayed into extremely small mist droplets, and the liquid and hot air are in parallel contact, and the water evaporates rapidly, which is extremely short. The product is dried into a finished product in a time, and the finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan.
The user can select the heating method and dust collection and dust removal methods according to the actual situation.
