Manufacture and Design of Vacuum Tray Dryer
Vacuum Tray Dryer is used mainly for drying of high grade,temperature and Oxygen sensitive products.It is the most commonly used batch dryer.It is highly suitable for drying hygroscopic substances, which are dried to very low residual moisture content level.
Vacuum tray dryer is wide used in intermediate pharmaceutical products,chemical,foodstuff and electronic industries.It is optionally available for Hot water system(Steam heated)with tank(insulated,SS304 Steam Radiator/Electrical heaters, circulation pump with FLP Motor and controls.
It is useful for processing of packaged food,Sterilization of Spices,Raw materials,petrochemicals,chemical specialties,chemicals, recycling, different type of sludge, molding friction and fiber compounds,Dyestuff,Plastics(fiber polymers), vacuum tray dryer for pharma, API Powders, Granular, and Flakes product Applications Powders,Non-Free Flowing,Ground coffee,Fertilizer,Flour Mixes,Soup Base,Cake Mix,Powders, Free flowing Drink Mixes,Coffee Beans,Potato Flakes,Whole Spices,Granular Sugar,Grass seed
