Multi effect falling film evaporator
Falling Film Evaporators offer distinct operating advantages in the concentration of many materials, senbofluid such as certain food products, fruit juices, pharmaceuticals and similar materials, which are particularly suited to evaporation in this type of equipment.
Our Falling Film Evaporators are unique in that they utilize novel operating principle from other types. The dilute liquid is fed to the top of the tubes, flows downward as evaporation occurs.
Uniform distribution of the liquid to the tubes is assured by an exclusive feature which controls the flow of the liquid to the top of the vertical heating tubes. The liquid flows over the edge of the tubes and runs down the inside surface in a thin, uniform film. The vapor travels down the tubes in the same direction as the liquid, gaining in velocity by the addition of more vapor as the mixture descends, resulting in high velocity for both the liquid and vapor.
Continuous feeding and discharging, the system is stable and easy to operate.
Senbofluid
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 and stable concentration and high efficiency, and can recover the solvent at the same time.
The energy saving effect is remarkable.
Senbofluid
The concentration ratio is significant (up to 1:5), thermal efficiency is high, and the energy saving effect is remarkable. In the structure of the system, we adopt an optimized design scheme to achievethe evaporation heat transfer coefficient 3400-3800w (m2·K), which is very suitable and advantageous for the concentration of Chinese herbal extracts. The main reason is that the material flows rapidly in the form of a film in the heating tube, 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. Senbofluid 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). It is not easy to crystallize and coke out due to heat, and the damage to the active ingredient is small, the heat energy is utilized sufficiently, and the energy saving effect is remarkable.
Easy to use advanced control methods.
Senbofluid
Because the LJN series concentrating process mainly uses the temperature of each effect as the control parameter, the parameters of the system are stable during operation, and it is easy to adopt advanced automatic control (PLC and humanmachine interface control), and the control equipment cost is relatively low, for the production of traditional Chinese medicine. Achieve greater automatic control with greater convenience.
The structure design is advanced and reasonable.
Senbofluid
In terms of structure, we adopt an optimized design scheme. I use advanced liquid distribution device to distribute the liquid in the pipe during the feeding, so that the material can enter the heating pipes evenly. At the same time, the inner wall mirror with high quality imported is selected. The tube is used as a heating tube, so that the flow resistance of the material in the tube is small, the speed is fast, and the scale is not easily precipitated. In order to improve the yield of concentration, the system is equipped with an advanced mist trap to eliminate the ability of entrainment of the mist, the separation efficiency can reach 96-99%, and the resistance drop is small.
Low steam consumption
Senbofluid
1kg steam can evaporte 3.5kg water.
Low evaporation temperature
Senbofluid
Part of secondary steam can be inhaled into single-effect heater through spray type hot pressure pump, this would make full use of the heat and the evaporation temperature is low.
