The device is to concentrate the material in the occasions such as China traditional drug、west、drug、dextrose、amylum sugar、oral liquid、chemistry、foodstuff、monosodium glutamate and vintage and to reclaim the industrial organic solvent such as alcohol. It is suitable to concentrate the thermal sensitive material under lower temperature and vacuum with little batch number and multiple varieties. Alcohol reclamation: The large reclamation capacity and the vacuum operation mode improve the craft process with a raclamation rate of alcohol of 90% and a loss rate of alcohol below 5%. The power consumption lowers for 30%, which improves that the device is a energy-saving equipment with economical investment and high reclamation economy profit. Cocentrated liquid material: The device uses the modes of outer-heated natural cycle and vacuum negative pressure evaporation featuring swift evaporation with concentration proportion of (1.4); The liquid material concentrates without bubble under full seal state. The drug liquid after concentration by the device features non-contamination and thick drug taste and easy cleaning (it is ust to open the up and down cover for cleaning.). The device is easy to handle and it needs a little foundation are for installation. The heater and Evaporator use stainless steel for thermal purpose. The polyurethane or pearl cotton is used as the thermal material. The surface is treated with sand grinding and surface polishing, meeting with the GMP standard.
