Concentrator
Double-effect Outer Circulation Concentrator

 

WZII Series double-effect external cycling type vacuum concentrator (alcohol can be recovered)

Usage

The concentrator can be applied to the concentration of solvent in the fields of Traditional Chinese Medicine, Western Medicine, glucose, starch, oral liquid, foodstuff and etc, especially the vacuum concentration of some heat-sensitive materials under the low temperature. Users can select different types of concentrator according to characteristics of various raw materials.

Characteristics and purposes:

  1. Excellent energy-saving advantage: Calculation is done based on the WZII1000 model. Users can save about 3500 tons of vapor, 90000 tons of water and 80000 kwh of power per annum, compared with the WZ1000 typeSingle-effect external cycling type evaporator.

  2. The concentrator features a combination of external heating recycling and vacuum negative pressure evaporation, with rapid evaporation speed and great concentration ratio. Foamless concentration of feed liquid can be realized inside the sealed tank, by which the liquid medicine is concentrated with no contamination or no strong smell of medicinal materials. Besides, it is easy to clean the vessel (All you need to do is to open the top head of the heater for cleaning).

  3. A double-effect simultaneous evaporation system is adopted for this concentrator. And secondary steam can be utilized fully. All these benefits result in great energy conservation, which can be best represented by a 50 percent deduction of the energy consumption compared with those single-effect concentrators.

  4. All the parts in contact with media are made of high-quality stainless steel, which meets the GMP standard. The heater and the evaporator of this device are all completed with insulation using the stainless steel cladding, which makes the whole equipment to be laid out reasonably and beautifully from the outside appearance. And an automatic condensed water outlet system can also be equipped as requested by our customers if necessary.
