Vacuum evaporation

it is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal. Although the process can be applied to any type of liquid at any vapor pressure, it is generally used to describe the boiling of water by lowering the container's internal pressure below standard atmospheric pressure and causing the water to boil at room temperature.

When the process is applied to food and the water is evaporated and removed, the food can be stored for long periods of time without spoiling. It is also used when boiling a substance at normal temperatures would chemically change the consistency of the product, such as egg whites coagulating when attempting to dehydrate the albumen into a powder.

Ethyl Alcohol recovery:recycle capacity is adjustable, adopt vacuum concentration processing.production ratio

improved 5-10 times than old same type equipment,energy consumption reduced 30%,with the

characteristic of lower investment cost and high recovery ratio.

Concentrated liquid:this equipment adopt combined outer heater natural external circulation and vacuum

pressure evaporation,evaporation quickly,concentration ratio could reach 1.3.

Ⅲ.Feature of Three Effect Energy Saving Evaporator

Energy Saving Benefit, calculated with GLWXH-1000 model,steam saving about 5400t/a,saving

water about 140,000t/a,totally about 200,000CNY.

This equipment adopt combined outer heater natural external circulation and vacuum pressure evaporation,

evaporation quickly,concentration ratio could reach 1.25-1.4(normal herbal liquid)

Evaporator adopt three effect evaporation at same time, secondary steam will be recycle use,consumption r

educed 67% than single effect evaporator,the saving money one year is worth the total evaporator equipment

cost.

The output from the evaporator with strong flavor,and one people will finish operation.

This equipment adopt stainless steel construction for contacting with material, insulation is polyurethane foam,

surface is mirror polish or honed polish, meet the GMP medicine standard.

Multiple functional characteristic:three effect could process different material separately, 1st, 2nd , 3rd effect

could discharge slurry repeatedly,also available for continue or batch operation.
