1. Drying powder, small granule and slurry materials under vacuum condition, especially for those materials which are heat sensitive, easy oxidized, toxic and the moisture is organic solution and need to be recovered;
2. Drying tray: 4-48 trays
3. GMP design
5. Heat source: steam or hot water
FZG series vacuum shelf tray dryer is a most often used static chamber dryer under vacuum condition. Inside the drying chamber, trays loaded with wet material are placed on top of each other in a drying shelf.
In drying pocess, heat medium, such as steam, hot water or thermal oil, is connected to the drying shelf which transfers heat to wet material. Under vacuum condition, boiling point of moisture is much lower. So the moisture can be evaporated under low temperature. The vacuum pump constantly sucks out the evaporated moisture to speed the drying process. Vacuum pump, tubular condenser and buffer tank are equipped to recover the evaporated moisture.
 Working principle |  Drying shelf and tray |
1) Flexibility in heat medium: Heat mediums can be steam, hot water or thermal oil to obtain different temperature according to special drying requirements.
2) Uniform drying: Four exhaust vents are equipped to make sure the evaporated moisture can be sucked out immediately.
3) Energy saving: The boiling point of moisture is much lower under vacuum. Low drying temperature can reach high evaporation rate.
4) GMP standard: Drying chamber is fully welded without dead corners to meet GMP standard.

A: Our vacuum shelf tray dryer can be specially designed according to specific material and capacity. Before we can work out a detailed proposal or quotation, we have to know the following information:
1) What wet material you are going to dry
2) Moisture content before drying
3) Final moisture content in dried product
4) Drying capacity in kg/day
5) What heat source you are going to use
6) Recommended drying temperature
A: The machine is packed in wooden boxes for shipping
Q: What kind of after sale service you can provide?
