China Cheap High Speed Centrifugal Spray Dryer
Spray drying suitable for the production of powdered, granular solid products from solutions, emulsions, suspensions and pasty liquid raw materials. Therefore, China cheap spray dryer is a very ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet the highest standards.
Spray drying is prepared from agricultural and forestry wastes (corn cob, bagasse, cottonseed husk, sunflower husk, birch sawdust) through hydrolysis, neutralization, decolorization, ion exchange, hydrogenation, concentration, crystallization,china high speed centrifugal spray dryer and other processes, Spray is a white crystal or powder, similar to soft white sugar, with similar calorific value and sweetness to sucrose, but its metabolism in the human body does not depend on insulin. It is a good adjuvant therapy and nutrition for diabetic patients. Its physiological function is similar to glycerin, it is widely used in food, military, daily chemical and other industries, the market is broad, and the development prospect is very good.
Working principle:
Spray drying is mainly processed by vibrating fluidized bed dryer. The characteristics of this equipment are that the wet material is not only subjected to the action of the hot air flow, but also is subjected to the action of the vibration exciting force during the china cheap spray dryer process, so that the material has a relatively high air volume. In a small case, it can form fluidization, reduce the amount of hot air, and reduce energy consumption; at the same time, the drying conditions and residence time of materials are also easy to adjust and control, which ensures the quality of dried products. During drying, the material fed into the fluidized bed is fully contacted with the hot air, tumbling and jumping, and advancing step by step under the action of the exciting force. The drying time is generally 10 to 60 minutes, and the solid content can reach more than 90% after drying. At the same time, in order to ensure the continuity of the subsequent operation of the material, a cooling section is added at the end of the dryer to reduce the temperature of the material after drying.

Suitable material:
Chemical industry: sodium (potassium) fluoride, 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.
Features:
1. The Spray production line adopts the form of a series combination of drying and cooling fluidized beds, which can not only meet the requirements of product moisture drying, but also meet the subsequent process requirements of the product.
2. drying and cooling medium circulation includes air filter, blower, induced draft fan, heater and air duct, etc. The air inlet duct is made of stainless steel to avoid the product being polluted by unclean air.
3. The upper bed of the host adopts a circular arc structure, which increases the boiling height and reduces dust entrainment.
4. The uniform air hole of the bed plate adopts a combined structure, the front section adopts tongue-shaped holes, so that the wet material can move forward smoothly without leakage, and the middle and rear sections use straight holes to increase the residence time of the material, so that the wet material The contact with the hot air is more sufficient, and the china high speed centrifugal spray dryer efficiency is improved.
5. The lower bed of the main engine adopts a plate structure and is supported by stainless steel seamless steel pipes. The bed structure is firm and has a long service life.
6. The interior of the lower bed of the main machine is made of stainless steel fully welded to prevent sewage from entering the insulation layer during cleaning, which affects the quality of the product. The cleaning port and sewage outlet are designed to facilitate cleaning of the equipment.
7. The system adopts two-stage dust removal, one-stage cyclone separator, and two-stage water film dust collector to improve the recovery rate of fine powder. The material and liquid in the water film dust collector can be returned to the previous process for secondary use.
