The company has extensively combined the advantages of concentrating equipment and other industry concentrating equipment, and combined with the characteristics of traditional Chinese medicine extracts, designed and developed a series of LJN three-effect (double-effect, single-effect)
falling film continuous feed concentrator. The features of the device are as follows:
1.Continuous feeding and discharging, the system is stable and easy to operate. When working in this series of equipment, it only needs to adjust various parameters as required at the initial feeding stage, and at the same time ensure continuous and stable supply of materials, convenient adjustment,continuous concentration, and meet the requirements of qualified specific gravity and can simultaneously recover the solvent.
2.The concentration ratio is large (up to 1.25-1.28), the thermal efficiency is high, and the energy saving effect is remarkable. In the structure of the system, we adopt an optimized design scheme to make the evaporation heat transfer coefficient reach 3400-3800w (m2·K), which is very suitable and beneficial for the concentration of Chinese herbal extracts. The main reason is that the materials are in the heating tube.
The film forms a rapid flow, and the heating temperature difference is small (only 8-10°C), the evaporation temperature is low, and the material can form a rapid flash after entering the evaporator. The residence time and heating time of the chemical liquid in the heating tube are short, and the viscosity of the material is wide (50-500 cp).
