It is widely used in medicine, chemical industry, foodstuff industry to concentrate for liquid material and recycle for organic solvent.Esp, suitable for thermally sensitive material.Such as alcohol extraction liquid, antibiotic zymotic liquid, fruit juice and milk etc under vacuum conditions to make low temperature to make low temperature consecutive conventration.As for multi-kinds and a little batch of material, it will be better. Feature and profit: 1.Alcohol recycling:Large recyclamation capacity and the vacuum contraction procedure make it's production capacity five to ten times of that of the old counterpart and can lower the energy consumption for 30%, featuring little investment and high reclamation profit. 2.Contracting liquid material:Thedevice uses the modes of outer-heated natural cycleand vacuum negative pressure evaporation featuring swift evaporation with concentration proportion of 1.3; The liquidmaterial concentrates without bubble under full seal state.The drugliquid after concentration by the device features non-contamination and thick drug taste and easy cleaning(open the up and down cover for cleaning).The device is easy to handle and it needs a little foundation area forinstallation. The heater and evaporator use stainless steel for thermal purpose.The polyurethane is used as the thermal material.The surface is treated with sand grinding and surfacepolishing, meeting with the GMP standard.
