The mechanism of Vacuum concentration machine

The boiling point of water increases when external pressure is high and decreases when it is low.
The heated solution can be concentrated at low temperature by heating under decompressed condition.

After materials are injected, vacuum pump will be started to decompress inside of the main tank , so that the boiling point of water in solution supplied decrease.
By setting a mixer inside the tank, it is possible to refrain the boiling of the solution.
The evaporated water is condensed at a surface condenser through a cyclone, and will be discharged as a drained water after collected in a drain tank.

Features of Vacuum concentration machine

  • Since materials are condensed at low temperature with being highly vacuumed, oxidization and deterioration by heat can be minimum, and the original flavor can be kept.
  • The temperature around this machine is near room temperature, since the solution is condensed at low temperature. Inside of the main tank is vacuumed and evaporated moisture is discharged as a drained water, so that this machine emits almost no odor during processing.
  • This can be utilized for condensation of solutions with high viscosity.
  • Mixing while heating prevents material from browning, and unevenness of temperature inside of main tank.
  • As it is possible to control automatically the volume of solution supplied to the main tank, this machine can have a compact design.

Frequently asked questions

How big is the maximum and minimum processing capacity of this machine?

This machine is a product we’re receiving orders for. For more details, please feel free to ask us.

Can you propose the detailed running cost?

Yes. If we can have information such as treatment capacity, time and condition, our sales staff will submit you the detailed running cost.

Can Yasujima make trial dried products in order to see what the finished condition of materials is like?

We have its small size test machine in our research laboratory and recommend that the customers considering to introduce this machine should perform pre-test.
During the trial, the customer can directly check the finished condition of materials, and obtained test data can be used as a base for design and manufacture of the real machine.
