5kg/H Single Effect FFE Evaporator Lab Stainless Steel Distillation CBD

Falling Film Evaporator Lab Stainless Steel Distillation CBD

Product Description

_{Falling film evaporators are widely used in the evaporation and concentration of water or organic solvent solutions in medicine, food, chemical, light industry and other industries, and waste liquid treatment. This equipment is especially suitable for heat-sensitive materials and continuous operation under vacuum and low temperature conditions. It has high evaporation capacity, energy saving and consumption reduction, low operating cost, and can ensure the invariance of materials during the evaporation process.}

Feature

The equipment operates continuously under vacuum and low temperature conditions, with large evaporation capacity, energy saving and consumption reduction, low operating cost, and can maintain the original composition of the processed materials to

he greatest extent.

It is widely used in food, medicine, food deep processing, beverage, light industry, environmental protection, chemical industry and other fields. The evaporator can be designed into different technological processes according to different material characteristics, and can also be equipped with an automatic control system according to the requirements of different users.​

Operation process

1. Exhaust the gas in the equipment to create a vacuum environment; after the vacuum is sufficient, add water to change the material.

2. Start the vacuum pump. If it is a water ring vacuum pump, it should be started without load.

3. When the pump is running and before starting, take care not to interrupt the cooling water of the pump mechanical seal to avoid damage to the pump mechanical seal.

4. When there is a sudden power failure, the valve should be closed immediately; the materials in the equipment and its pipelines should be discharged as soon as possible; the heated water should be diluted until it does not crystallize or solidify.

5. During operation, if the vacuum is low or after restarting, check whether there is air leakage at the flange and joints immediately.

Working Theory
This equipment belongs to liquid film concentration equipment, which has high heat transfer rate and short heating time. It applies to chemical, liquid medicine, juice, and dairy production.
The theory is that the feed liquid is added in the middle of the evaporation chamber. Under the action of vacuum and gravity, the accelerating pressure head of the liquid is smaller than that of the rising film type, and the boiling point is also smaller. The temperature difference between the electric heating and the feed liquid is large, so the heat transfer effect is better.The steam enters the evaporative separation chamber for separation. The secondary steam is discharged from the top of the chamber and the concentrate is extracted from the bottom.

Maintenance

1. Always check whether the oil cup of the pump is short of oil, and whether the cooling water in the mechanical seal is broken.
2. Always check the flanges and joints of the equipment for air leakage.
3. When the mechanical seal of the pump is damaged, it should be replaced in time.
4. When the check valve rubber ball and rubber gasket are damaged, they should be replaced in time.
5. If the indications such as thermometer, vacuum gauge, pressure gauge, etc. are inaccurate, they should be proofread or replaced in time.
6. The surface of the equipment should not be rubbed with a hard scrubbing tool (such as steel brush) to avoid scratches and scratches on the stainless steel surface.
