Operating Procedures for Thin Film Evaporators

1. Installation
The entire trial operation has been carried out before the product leaves the factory. Users can lift the entire equipment onto the equipment foundation and fix it on the floor or steel frame.
The equipment should be leveled as a whole, and the leveling position can refer to the plane on the reducer frame. For larger equipment, in order to increase the stability of the equipment, a horizontal auxiliary bracket can be added at an appropriate position on the upper part of the bottom flange. The auxiliary pivot only limits the radial displacement of the device, not its axial displacement.
2. Preparation before driving
The product has undergone hydrostatic testing and trial operation before leaving the factory, and all indicators meet the requirements of the drawings.
Start the motor and check if the mixing meets the required rotation direction on the drawing. Rotate clockwise in the top view without reversing.
Determine whether the radial swing and axial displacement of the shaft at the mechanical seal meet the requirements of the drawing, and check whether the upper end and cover of the mechanical seal are tightened. The cover should be in a tightened state.
Check the oil level of the gearbox, which should be within the normal range.
3. Normal driving
Firstly, start the circulating cooling water pump to operate the hydraulic jet condenser. Open the concentrated solution container and drain the valve.
Open the feed valve and pump the liquid from the high-level tank into the equipment through vacuum degree.
Connect the power supply, start the motor of the rotating thin film evaporator, and observe whether the direction of rotation of the motor is correct.
Slowly open the steam valve to allow steam to enter the jacket, discharge non condensable gases from the jacket through the bypass valve, and then open the drain valve. Adjust the steam pressure to approximately 0.15 MPa.
Observe the discharge situation from the bottom mirror and strictly prohibit operation when the equipment is filled with liquid.
After the system stabilizes for 5 minutes, sample and analyze the concentration of the concentrated solution, adjust the opening of the feed valve, and make the concentrated solution reach the predetermined required concentration

Core application areas and functions of thin film evaporators
Thin film evaporators, with their characteristics of efficient heat transfer, short material residence time, and flexible operation, undertake key separation, concentration, and purification tasks in multiple industrial fields. The following are its main application scenarios and specific uses:
1、 Chemical Industry: Separation, Purification, and Resource Recovery
Core application: Used for solvent recovery, wastewater treatment, removal of light components from high viscosity materials, and separation of mixtures.
Treating waste gas and residues in chemical reactions, achieving environmental standards through concentration and purification, or recovering useful substances.
Separate mixtures with similar boiling points (such as fatty acids, glycerides), or remove residual monomers from polymer solutions (such as polyurethane, resins).
In the petrochemical industry, heavy oil, asphalt and other high viscosity materials are subjected to light component removal operations to reduce waste volume.
2、 Pharmaceutical and Medical Industries: High precision Purification and Active Ingredient Retention
Core applications: drug concentration, solvent removal, and separation of active ingredients, meeting the strict requirements of the pharmaceutical industry for purity and stability.
Concentrate drug solutions, remove solvents, recover organic matter, separate and purify active ingredients such as antibiotics, and avoid high temperature damage to drug efficacy.
Used in the medical field for blood separation and concentration, removing water and impurities to extract pure components.
3、 Food and Beverage Industry: Concentration and Quality Assurance
Core application: Concentrate liquid food and preserve flavor compounds, balancing efficiency and product quality.
Concentrated fruit juice, dairy products, coffee extracts, alcohol, etc., remove moisture while retaining nutrients and taste.
Handle heat sensitive materials such as natural pigments and essence, and avoid coking or deterioration by heating for a short time.
4、 Environmental Protection and Energy Sector: Wastewater Treatment and Resource Recycling
Core application: High concentration wastewater treatment and renewable resource recycling, supporting environmental protection and sustainable energy development.
Concentrate dissolved substances in wastewater, recover volatile organic compounds (such as ethanol and acetone), and reduce waste liquid emissions.
Used in the field of energy for seawater desalination and biomass energy production (such as bioethanol concentration). Industrial wastewater treatment equipment
5、 Metallurgy and other specialized fields
Metallurgical industry: Concentrate ore slurry, recover valuable metals or compounds, and efficiently process high concentration suspensions.
Biological fermentation industry: Participate in the concentration and purification of fermentation products to ensure the stability of bioactive substances.
Key features support multi domain applications
The efficient heat transfer, low energy consumption, and short residence time of thin film evaporators make them particularly suitable for heat sensitive, high viscosity, or easily crystallizable materials. The parts in contact with the materials are made of stainless steel, meeting corrosion resistance and hygiene standards (such as in the pharmaceutical and food industries). Different types (rising film, falling film, scraping film) can be flexibly selected according to process requirements, further expanding application scenarios.
