Rising film evaporator
Rising film evaporator
The material liquid is preheated to the boiling point, is added from the bottom of the heating chamber, and is strongly vaporized in the heating tube, so that the generated vapor drives the material liquid to rise in a film-like evaporator along the tube wall. The liquid film continues to evaporate as it rises.

The material liquid is preheated to the boiling point, is added from the bottom of the heating chamber, and is strongly vaporized in the heating tube, so that the generated vapor drives the material liquid to rise in a film-like evaporator along the tube wall. The liquid film continues to evaporate as it rises. The solution only needs to pass through the heating tube once to reach the required concentration. This evaporator is suitable for dilute solutions and heat-sensitive materials that are not highly concentrated.
TOPTION rising film evaporator is used to remove and recover most of the ethanol to obtain an extract with only a small amount of ethanol remaining. 200L/hr~1000L/hr evaporation capacity flexible design, the ethanol recovery rate can be as high as 95%.
1. Continuous evaporation process & safe operation.
High precision gear pump for automatic | stable | continuously material feeding / discharging.
2. Rising film evaporator for Fast evaporation, use smaller equipment to produce more products.
3. Stainless steel condensing net accelerates separation, improves product purity, and reduces heavy component waste.
4. Plate heat exchanger + condenser enhances condensation collection capacity, Minimize solvent waste.
5. Reduces the connect time of the vacuum equipment and system, reduces the solvent loss caused by the vacuum gas flow.
6. Liquid level transmitter design, the solvent can be continuously & automatically output, and the distilled solvent is discharged without stopping the operation.
7. Discharge / Reflux pump design, If the residual solvent does not meet the requirements after the first evaporation, the evaporation can be recycled.
Advantages compared with traditional evaporators
1. High thermal conductivity, the same evaporation area, the rising film evaporates faster than the traditional falling film. Therefore, with the same evaporation speed, the evaporation area required for the rising film evaporator is smaller, and the device size is also smaller (Much smaller).
2.The required vacuum is smaller, which is more conducive to the condensation and recovery of the solvent.
3. Plate heat exchanger 1+1 to enhance the condensation collection capacity.
4. Higher solvent collection rate, less solvent waste.
5. Steam and mist can be better separated in the separation chamber, reduce the loss of heavy components, and improve the purity of the recovered light components.
