 Vacuum Belt Continuous Dryer For Liquid

The vacuum belt continuous dryer for liquid is designed to solve the problems associated with extracting highly concentrated materials in viscous products. Traditionally, a centrifugal spray dryer would damage the thermally sensitive components and lead to materials sticking to the walls of the dryer. Also, regular vacuum ovens are not ideal for these types of operations because the ovens take long periods of time for drying and require large amounts of energy. This tray dryer is ideal because it features a low drying temperature with excellent sanitary features and it can fully meet GMP requirements.

Range of application:

  • 1. Plant extracts
  • 2. Hydrolyzed vegetable proteins (HVP)
  • 3. Bakery products
  • 4. Pharmaceutical products
  • 5. Fruit juice concentrates
  • 6. Instant coffee
  • 7. Meat extracts
  • 8. Malt drinks
  • 9. Chemical powder
  • 10. Sticky powder

Work Flow
This drying equipment features a vacuum chamber where a material conveying guide belt (Teflon PTFE) is installed. Materials are distributed continuously on the guide belt after they pass through the continuous vacuum distributor at the top of the machine (adjustable distribution thickness 3mm-30mm). The guide belt conveys the material slowly to the other end while the heating zone (40℃-180℃) below the belt evaporates moisture within the compound. Evaporated moisture is quickly removed by the vacuum system. The compound automatically falls onto the second layer guide belt when it reaches the end. The process repeats until the desired dryness is achieved. When it is finished, materials will fall into the conveying chute at the discharging end where a screw conveyor will deliver it to other processing equipment to be ground, sieved and pulverized.

Notes ① The yield is calculated based on 70% content at 90℃ drying temperature with dry power containing about ≤4% moisture, in case the dried liquid is water, specific gravity of the dry power is determined to be 1.
The yield will be larger if the dried liquid is solvent.
② All technical parameters are for reference only depending on the material conditions, and our company has the right to change them without further notice.
