Raw Material Drying

Spray drying is widely used to make liquids into powders, granules or hollow spheres. With the continuous development of spray drying technology, its application covers almost all industries, and greatly simplifies the production process of industrial products, saves investment costs, improves labor conditions, and at the same time, improves product output and quality. Spray drying technology has been widely used in chemistry, food, medicine, forestry, pesticides, ceramics, cement, metallurgy and other fields.

In the ceramic building materials industry, drying is one of the most important processes in the ceramic production process. Spray drying is to spray the ceramic mud into droplets with a spray gun in the drying tower, and contact the hot air entering from the top of the spray drying tower. The mist droplets are fine and have a huge evaporation area. The drying is completed almost instantaneously, and the required granular powder is obtained, which is accumulated at the bottom of the tower and discharged by the discharge valve.

RELAB's centrifugal spray drying nozzles are an important part of the dryer. High-speed centrifugal spray dryers are widely used in liquid forming processes and drying industries.

The liquid material passes through the peristaltic pump according to the operating instructions, enters the high-speed rotating centrifugal nozzle, and is dispersed into small droplets under the action of centrifugal force. In the main spray drying tower, the small droplets are in full contact with the hot air, and after heat exchange along their specific paths, they are dried into products, and then separated by a cyclone separator, the solid materials are collected, and the gas medium is filtered and discharged. . The entire spray system is easy to clean, has no dead ends, and meets GMP requirements.

RELAB's spray drying nozzles are also used in the following areas:

• Chemical industry: sodium fluoride (potassium), basic dyes and pigments, dye intermediates, compound fertilizers, formaldehyde silicic acid, catalysts, sulfuric acid agents, amino acids, white carbon black, etc.
• Plastic resin: AB, ABS emulsion, urea-formaldehyde resin, phenolic resin, glue (urea) formaldehyde resin, polyethylene, polyvinyl chloride, etc.
• Food industry: fat-rich milk powder, gluten, cocoa milk powder, milk replacer powder, hunting blood powder, egg white (yellow), etc.
• Food and plants: oats, chicken juice, coffee, instant tea, seasoning meat, protein, soybean, peanut protein, hydrolyzate, etc.
• Sugars: corn steep liquor, corn starch, glucose, pectin, maltose, potassium sorbate, etc.
• Ceramics: alumina, tile materials, magnesia, talc, etc.
