High quality vacuum drying oven fruits and vegetables vacuum drying machine industrial vacuum tray dryer
Vacuum drying equipment is divided into static dryer and dynamic dryer. YZG cylindrical and FZG square vacuum dryer belongs to static vacuum dryer to heat and dry the raw materials under vacuum conditions.When the material is dried in the static dryer, the material is in a static state, so the shape will not be damaged. It is If the vacuum pump is used for air and moisture extraction, the drying speed is accelerated. Note: if a condenser is used, the solvent in the material can be recovered through the condenser; If the solvent is water, the condenser can not be used to save energy investment.
FEATURES AT A GLANCE
SIMPLE CONTROL
LOW TEMP DRYING
SAFETY OPERATION
SMALL OCCUPATION
EASY MAINTENANCE
COMPACT STRUCTURE
STATIC VACUUM DRYING
The boiling point of the material decreases under vacuum, which increases the heat transfer driving force of the machine. Therefore, for a certain heat transfer, the heat transfer area of the evaporation can be saved.
the heat source of evaporation operation can be low-pressure steam or waste heat steam.
has less heat loss.
disinfection treatment can be carried out before drying. There is no impurity in the drying process, which meets the requirements of GMP.
it belongs to static vacuum dryer, so the body of dried materials will not be damaged.
Working Principle
The FZG / YZG vacuum drying oven 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.
Application Field
YZG cylindrical /FZG square vacuum dryer is suitable for low temperature drying of heat sensitive materials which are easy to decompose, polymerize and deteriorate at high temperature. At present, YZG cylindrical /FZG square vacuum dryer has been widely used in high-tech, chemical, food, dye, electronics and other industries, the products meet the requirements of GMP standards.
