FZG-8 Square Fruits and vegetables vacuum drying machines / vacuum drying oven

FZG-8 includes:  8 pcs of Trays.

Product Description:

It is suitable for drying heat sensitive raw materials that can decompose and polymerize and metamorphose at high temperature .It is wide used in pharmaceutical , chemical ,foodstuff electronic industries.

Vacuum drying is to put raw material under the state of vacuum for heating and drying. If use vacuum to pump air and humidity out, the dry speed will be faster.

Note: if use condenser, the solvent in raw material can be recovered. If the solvent is water, condenser might be canceled and the investment and every could be saved. it use SK series water ring vacuum pump sets, condensate can not be used and the investment could be saved.

Principle:

Vacuum drying is a process in which materials are dried in a reduced pressure environment, which lowers the heat needed for rapid drying. It does not take place in a true vacuum, despite the name. Devices used for this process are known as vacuum driers, and can vary in size from small units designed to fit on kitchen counters to massive rooms which are used to handle things like timber products.

Drying involves reducing the moisture in an object, and is done in environments where the air is drier than the object being dried, which encourages moisture to evaporate out. This is often accomplished with heat to reduce the humidity of the air, but in a vacuum drier, the temperature does not need to be as high, and the drying is often faster. It's also possible to achieve a very high level of dryness, which may be desirable in some cases.
