LPG Series Gum Arabic Spray Dryer
Description
The spray dryer is a wide applied process in liquid process shaping and drying industry. Particularly it is suitable for producing powder, granule or block solid product from solution, emulsion, suspending liquid and pumped paste liquid. Therefore when the distribution of granule size, final moisture, bulk density, granule shape of finished product must be conformed to accuracy standard, the spray drying is an ideal process.
Principle
It's widely used in foodstuff, pharmaceutical, and chemical industry, such as egg powder, amino acid product, protein, blood, food flavor, food ingredients, pectin, carrageenan, spirulina, herbal extraction, pigment, cocoa, mushroom, PAC, malt dextrin, collagen, juice , yeast, Coffee, Creamer, coconut, milk, gelatin, gum and acacia etc.
Features
After filtering and heating, the hot fresh air enter into the air distributor at the top of drying chamber, distributed in spiral way uniformly from up to down. At the same time, the feeding liquid is pumped to the top atomizer, then be sprayed to extremely fine mist liquid drop. Through the short time of direct contact with hot air, the moisture evaporated at once, the solid remains to be powder. The dry powder will be discharged continuously from the bottom of drying tower and cyclone collector, the exhaust air will be discharged after cleaning.
