What is Vacuum Belt Dryer?
vacuum belt dryer is a brand-new concept of drying equipment.Compared with the traditional spray drying and freeze drying methods, it is featured with full-automatic, low-temperature, continuous , energy-efficient, and it is applied to more areas.
Comparison Between Vacuum Drying, Spray Drying and Freeze Drying.
1.Spray Drying has the advantage of investment cost, however, there are many limitations in the solubility,nutrients-loss, original flavor loss and shape control of powder. There is nothing spray dryer can do when it comes to slightly higher-viscosity and heat-sensitive products.
2.Freeze-drying can obtain products with excellent solubility and high-quality, but the output is too low and expensive.
3.vacuum belt dryer is just between the above two dryers, both the temp and vacuum degree can be adjustable ,so it can make the drying products to have porous and loosen internal structure, remain the products’ original nutrients and good appearance. MJ-series Full-automatic low-temperature continuous vacuum belt dryer realizes continuous feeding and discharging under vacuum, and successfully transforms static drying into dynamic drying. Which not only greatly improves the output of dried products, but also reduces the production cost.

Advantages of Vacuum Belt Dryer
- Full processes are automatic, pipelining and continuous.
- Continuous feeding and discharging.continuous drying, crushing and granulation, under vacuum status
- Organic solvent（ such as Alcohols,Aromatic hydrocarbon,Ether and so on)can be recovered during the drying process
- High vacuum degree -0.099PM, adjustable drying temperature(25℃～150℃).
- 30-60 mins continuous powder discharging and powder yield reaches 99.99%.
- CIP cleaning system, GPM standard
- Labor-saving, 2 operators at most.
What can be dried with Vacuum Belt Dryer?
- Food and Beverage: various vegetable and fruit juice,Instant Tea/Coffee/Chocolate/Malted drinks,Artificial flavourings
- Chemical products:Synthetic lysine (L-lysine),Anti biomass,Powdered natural paint，
- Pharmaceutical products: herb/plants extract,Traditional Chinese medicine essence,pills.
- Industrial products:Li-battery electrolyte,Hazardous Chemical,Agricultural chemicals，Cobalt products. Copper products
