Wiped Film Evaporator Guide

The wiped film evaporator is a commonly used chemical equipment, which is widely used in evaporation and concentration processes in the fields of pharmaceuticals, chemicals, and food. The following is a guide for wiped film evaporators, including working principles, operating procedures, maintenance and more.

1. Working principle

The wiped film evaporator is a device that uses a scraper to scrape the film-like liquid formed by the solution from the inner wall of the evaporator for evaporation and concentration.

Its working principle is that the liquid is heated and evaporated, the solute is separated, the film-like liquid is scraped off by the scraper, and after passing through the heating and evaporation area inside the evaporator, two phases of gas phase and liquid phase are formed, and then separated by a decompression device.

2. Operating procedures

1. The wiped film evaporator needs to be inspected before use to ensure that all parts of the equipment are operating normally and there is no peculiar smell and noise.

2. The equipment needs to be cleaned before operation, and corresponding solutions or chemical reagents should be added as needed.

3. After heating the equipment to the proper temperature, the solution is added to the evaporator.

4. Adjust as needed to control scraper speed and flow rate.

5. When finished, switch off the unit for cleaning and maintenance.

3. Maintenance

1. Regularly check the operation status of the equipment, if there is any abnormality, it should be checked and repaired in time.

2. Clean and disinfect the equipment frequently to ensure the sanitation and safety of the equipment.

3. Regularly replace the wearing parts of the equipment, such as scrapers, sealing rings, etc.

4. Regular maintenance of equipment, such as oil lubrication, cleaning and rust prevention, etc.

In short, the wiped film evaporator is a commonly used chemical equipment. Its working principle is to use a scraper to scrape the film-like liquid formed by the solution from the inner wall of the evaporator for evaporation and concentration. When using a wiped film evaporator, it is necessary to pay attention to the operating procedures and maintenance to ensure the normal operation and service life of the equipment.
