Single effect external circulation falling film evaporation concentrator

[Equipment description]

Falling film evaporation is to add the material liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into the heat exchange tubes through the liquid distribution and film forming device. Under the action of gravity, vacuum induction and air flow, it becomes a uniform film. Flow from top to bottom. During the flow process, it is heated and vaporized by the heating medium in the shell side. The generated steam and liquid phase enter the separation chamber of the evaporator. After the vapor and liquid are fully separated, the steam enters the condenser for condensation (single-effect operation) or enters the next-effect evaporator as The medium is heated to achieve multi-effect operation, and the liquid phase is discharged from the separation chamber.

The falling film evaporator includes a heating heat exchanger, which is formed with a feed inlet, and the heating heat exchanger is connected with the top of the integrated falling film evaporator; The bottom of the falling film evaporator is connected with a circulating pump, and the circulating pump is connected with a finished product tank; The heating cavity of the integrated falling film evaporator is communicated with an air inlet pipe and an air outlet pipe, and is communicated with a heater; The air outlet of the integrated falling film evaporator is connected with the heating chamber of the heating heat exchanger, the heating chamber of the heating heat exchanger is connected with the first cooling heat exchanger, the first cooling heat exchanger is connected with the transfer tank through the vacuum pump, the transfer tank is connected with the second cooling heat exchanger, and the second cooling heat exchanger is connected with the alcohol recovery tank.

Single effect falling film concentration evaporator is used for low-temperature evaporation of liquid in food, chemical industry, medicine and other industries. It can continuously feed and unload materials. The heating time of materials is short, and the evaporation temperature is low. The liquid can reach the required concentration through the equipment once. It has little effect on the color, flavor and nutrition of the product, and is especially suitable for the evaporation of heat sensitive materials such as milk.

It consists of single-effect heater, single-effect evaporative separator, condenser, vacuum pump, feed pump, circulating discharge pump, condensate pump, control box, stainless steel support, pipelines and valves.

[Working principle of hemp Cannabis CBD extraction and concentration equipment]

CBD, namely cannabinoid, is a natural product extracted from hemp, which is different from other hemp extracts and is not addictive and hallucinogenic. It has high medicinal value. It has been proved that it can cure epilepsy, improve mood, reduce dependence on alcohol and nicotine, resist anxiety and inflammation, and relieve joint and nerve pain.

The materials are evenly distributed on the inner wall of the falling film tube from the top of the falling film chamber through the film distribution device, and flow from top to bottom in the form of a film by its own gravity and secondary steam flow. At the same time, the materials and secondary steam are evaporated by heat exchange with the heating steam on the outer wall of the falling film tube. The evaporated materials and secondary steam enter the separated type for gas-liquid separation. The materials are sent out through the discharge pump. If the material concentration does not meet the requirements, the steam volume is adjusted through the plunger valve, Ensure the concentration of outlet materials. The secondary steam enters the service condenser and is cooled with cooling water. The non condensable gas is sucked out by the vacuum pump, and the system is guaranteed to work under vacuum.

[main features]

[Features of DOVMXTECH falling film evaporator]

1. Low heating temperature

2. High evaporation speed

3. Short liquid residence time

4. Continuously feeding and discharging

5. Suitable for heat sensitive materials

6. Energy-saving

DOVMXTECH automatic falling film evaporator is designed to let the mixed fluid flow down the pipe wall to form a continuous film, so as to uniformly and continuously evaporate. The separation of internally vaporized fluid, liquid (solution) and gas occurs in the pipeline. The system operates under vacuum to allow low temperature separation.

DOVMXTECH falling film evaporator belongs to a movable device. According to the characteristics of hemp extraction, the liquid inlet and steam are exchanged for heat, so as to save energy, improve the extraction efficiency, facilitate movement and reduce the complexity of operation.
