Our company extensively combines imported concentration equipment with other industry concentration equipment, and combines the characteristics of traditional Chinese medicine extract to design and develop the JBM type three effect (double effect, single effect) falling film continuous feed concentrator.

Features and Benefits

1. Continuous feeding and discharging, stable system, easy operation. During operation, this series of equipment only needs to adjust various parameters as required in the initial feeding stage, while ensuring continuous and stable supply of materials. The adjustment is convenient, and it can concentrate continuously, stably, and efficiently to meet the required specific gravity and recover solvents simultaneously.

2. Concentrated specific gravity (up to 1.25-1.28), high thermal efficiency, and significant energy-saving effect. In the structure of this system, we adopt an optimized design scheme to achieve an evaporation heat transfer coefficient of 3400-3800w (m ² · K), which is very suitable and advantageous for the concentration of traditional Chinese medicine extract. The main reason is that the material forms a film like rapid flow in the heating tube, and the heating temperature difference is small (only 8-10 ℃). The evaporation temperature is low, and the material can form rapid flash evaporation after entering the evaporator. The residence and heating time of the medicine in the heating tube are short, and the viscosity adaptation range of the material is wide (50-500cP). The heating is uniform and not easy to crystallize and precipitate, and the damage to the effective components is small. The utilization of heat energy is divided, and the energy-saving effect is obvious.

3. Easy to adopt advanced control methods. Due to the fact that the "series concentration process mainly uses the temperature of each effect as the control parameter, the system operates with stable parameters, making it easy to adopt advanced automatic control and human-machine interface control. Moreover, the cost of control equipment is relatively low, which greatly facilitates the full automatic control of traditional Chinese medicine production.

4. Advanced and reasonable structural design. In terms of structure, we adopt an optimized design scheme and use advanced liquid distribution devices for the distribution of feed liquid and the flow inside the tube, so that the material can enter each heating tube evenly. At the same time, we choose high-quality inner wall mirror tubes as heating tubes to reduce the flow resistance and speed of the material inside the tube, making it less prone to scaling. To improve the yield of concentration, the system is equipped with advanced mist collectors that have strong ability to eliminate mist entrainment, with a separation efficiency of 96-99% and a reduced resistance.
