Plant extracts are extracted by solvent and enriched by means of concentration; these plant extracts are most sensitive. Typical plant extracts include traditional Chinese medicine, tobacco, natural flavors, spices etc. Conventional evaporation concentration equipment will lead to higher concentration temperature and longer heating time; these factors will affect the quality of the active ingredients.
Thin film evaporator can achieve a high vacuum degree; can provide lower evaporation temperature for plant extracts. The residence time is also short which can guarantee on the product quality.
