Low temperature concentration equipmentGood process adaptability. Water extraction and alcohol extraction can be carried out using atmospheric pressure, negative pressure, and positive pressure processes, especially for low-temperature extraction and concentration of thermosensitive materials. Water extraction can be carried out at temperatures above 45 ℃. Traditional Chinese Medicine Extraction Equipment
High cream yield. Due to the dynamic extraction of drugs, there is a high solute gradient between the drug and the solvent, which increases the leaching driving force and improves the yield of the paste. Can increase by 5% -20% or more compared to conventional methods. Save solvents. Fully enclosed closed-loop circulation can save 30% -50%. Save time. Extraction and concentration are completed in one step, and this unit uses a reflux rate twice that of conventional methods, with the entire process taking only 4-6 hours. Low temperature vacuum drying equipment
Reduced energy consumption. Due to the use of secondary steam as the heat source, extraction and concentration are carried out simultaneously, and the temperature of the reflux condensate is close to the boiling temperature inside the extraction tank; And there is also on-site foaming of polyurethane as an insulation layer, and the temperature and vacuum degree are randomly controlled. This unit can save more than 50% of steam.

1、 Introduction to Low Temperature Concentration Equipment Products
Low temperature concentration equipmentIt is a new type of concentrator developed by our company in recent years, mainly suitable for concentrating thermosensitive materials in the pharmaceutical, food, biological, and chemical industries. The concentration temperature can be between 40-50 ℃. This equipment has changed the traditional concentration and concentration process from high temperature, easy material variability, easy scaling during the concentration process, and poor flowability due to increased material concentration, making it impossible to continue concentration. Due to the low concentration temperature of the material in the equipment, the effective components of the material are greatly preserved, meeting the requirements of users for concentrated products.
2、 Process flow
Low temperature concentration equipmentBy using high vacuum airdrop and low concentration evaporation temperature, a rotating tube type drum is designed inside the evaporator to increase the heating area. The drum and jacket are heated with hot water. Due to the continuous rotation of the drum, a thin film evaporation principle is formed, and the material continuously contacts the surface of the tube and evaporates. Intermittent or continuous concentration can be achieved in a vacuum state.
3、 Equipment structure
Low temperature concentration equipmentIt mainly includes the main evaporator, evaporator drum, reducer, separation chamber, circulating pump, preheater, sprinkler head, defoamer, condenser, cooler, and liquid receiving tank. The evaporator drum is located inside the evaporator tank, and one end of the evaporator drum has a heat source inlet and outlet. The lower end of the main evaporation tank has a discharge port, which is connected to a circulation pump to form a forced circulation spray to accelerate the concentration rate, and the top is connected to a defoamer. The characteristics of this utility model are: compact structure, reasonable layout, and no material loss due to the installation of defoamers.
