spray dryingIt is a widely used process in the liquid process forming and drying industry. Suitable for producing powdery and granular solid products from solutions, emulsions, suspensions and pasty liquid raw materials. Therefore, spray drying is a better process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet standards.
Working principle:
  The air is filtered and heated and enters the air distributor at the top of the dryer. The hot air enters the drying chamber evenly in a spiral shape. The feed liquid is sprayed (rotated) into extremely fine mist liquid beads through a high-speed centrifugal atomizer at the top of the tower body, and can be dried into finished products in a very short time when it comes into parallel contact with hot air. The finished product is continuously output from the bottom of the drying tower and from the cyclone separator, and the exhaust gas is evacuated by a fan.
Performance characteristics:
◎ The drying speed is fast. 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. The drying time only takes a few seconds. It is especially suitable for drying heat-sensitive materials.
◎ The product has good uniformity, fluidity and solubility, high purity and good quality.
◎ The production process is simplified and the operation and control are convenient. For liquids with a moisture content of 40-60%(up to 90% for special materials), it can be dried into powder products at one time. After drying, there is no need to crush and screen, which reduces production processes and improves product purity. The product particle size, bulk density, and moisture content can be adjusted within a certain range by changing operating conditions, making it convenient to control and manage.
Adapted materials:

Chemical industry: sodium fluoride (potassium), basic dye pigments, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acids, amino acids, white carbon black, etc.

Plastic resins: AB, ABS emulsion, urea-formaldehyde resin, phenolic resin, dense glue (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc.
Food industry: Fat-rich milk powder, gelatin, cocoa milk powder, milk substitute, hunting blood powder, egg white (yellow), etc.
Food and plants: oats, chicken juice, coffee, instant tea, flavored meat, protein, soybean, peanut protein, hydrolysate, etc.
Sugar: corn steep liquor, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.

Disc continuous dryerIt is an efficient conductive continuous drying equipment. Its unique structure and working principle determine that it has the characteristics of high thermal efficiency, low energy consumption, small floor area, simple configuration, convenient operation and control, and good operating environment. It is widely used in chemical, medicine, pesticides, food, feed, agricultural and sideline product processing and other industries. Drying operations. It has been well received in practice in various industries. Working principle:
  Wet materials are continuously added from the feeder to the drying tray on the upper part of the dryer. The harrow arm with harrow blades makes a rotary motion to make the harrow arm make a rotary motion to make the harrow blades continuously turn over the materials. The material flows along the surface of the drying pan along an exponential spiral. The material on the small drying pan is transferred to the outer edge and falls to the outer edge of the large drying pan below. On the large drying pan, the material moves inward and falls from the middle drop. Drop into the next layer of small drying pan. Large and small drying trays are arranged alternately up and down so that the material can flow continuously through the entire dryer. Heating medium is introduced into the hollow drying plate. The heating medium takes the form of saturated steam, hot water and heat transfer oil. The heating medium enters from one end of the drying plate and is led out from the other end. The dried material falls from the bottom layer of the drying tray to the bottom layer of the shell, and is then transferred to the discharge port by the rake blades. Moisture escapes from the material and is discharged through the moisture outlet arranged on the top cover. Moisture from the vacuum type tray dryer is discharged through the vacuum pump outlet arranged on the top cover. Dry material discharged from the bottom layer can be packaged directly. By adding auxiliary machines such as finned heaters, solvent recovery condensers, bag filters, dry material back-mixing mechanisms, and induced draft fans, its drying production capacity can be improved. Paste paste and heat-sensitive materials can be dried, and solvents can be easily recovered., and pyrolysis and reaction operations can be carried out.
Performance characteristics:
1. Easy to control and strong applicability;
2. Simple and easy operation;
3. Low energy consumption;
