Description
Technical Parameters
Rotary thin film evaporator is an efficient evaporation device mainly used for processing liquid materials such as solutions, solvents, mixtures, etc. It forms a thin film of liquid materials in the evaporator by rotating the film, thereby achieving a fast and efficient evaporation process.
Product Application
Rotary Thin Film Evaporator, as an efficient and multifunctional evaporation equipment, has been widely used in various fields such as chemical, pharmaceutical, and food. Its unique working principle and structural design make it excellent in handling high viscosity, thermal sensitivity, and easily crystallized materials.
Basic principle:
The working principle of a rotating thin film evaporator is mainly based on the centrifugal force and steam thermal energy generated by high-speed rotation.
The core lies in forcing the material to form a uniform and extremely thin film on the inner wall of the evaporator through a rotating scraper, which is heated under low pressure to achieve rapid evaporation and solid-liquid separation.
Structural composition:
It mainly consists of a heater, an evaporation chamber, a condenser, a vacuum system, liquid inlet and outlet, and driving devices (such as motors and reducers).
Among them, there are special rotating scrapers in the evaporation chamber, which are driven by motors and reducers and rotate at a certain speed to scrape the material into a uniform thin film on the wall of the evaporation chamber.
Working Process
Material addition and vacuum formation:
The liquid to be processed is first added to the evaporation chamber, and then the vacuum system is activated to form a certain degree of vacuum between the evaporation chamber and the condenser.
This step is crucial for controlling the evaporation rate and reducing the boiling point of the material.
Film formation and heating:
Heat the rotary scraper inside the evaporator chamber and the evaporator chamber itself to a certain temperature through a heater. As the scraper rotates, the material is evenly coated on the wall of the evaporator, forming an extremely thin film. This thin film greatly increases the evaporation area and improves heat transfer efficiency.
Evaporation and gas separation:
Under vacuum conditions, the liquid in the film rapidly evaporates, and the generated vapor separates from the solid particles that have not evaporated at the top of the evaporator. The steam then enters the condenser and condenses into a liquid after being cooled by cooling water, thereby collecting the evaporated solute. And the solid particles fall back to the bottom of the evaporator, waiting to be scraped up again by the scraper to form a new thin film.
Residual liquid discharge:
After a period of evaporation, the residual liquid in the evaporator is discharged through the liquid outlet, completing the entire solid-liquid separation process.
Features and advantages
Efficient and energy-saving
The rotating thin film evaporator has extremely high heat transfer coefficient and evaporation efficiency, which can complete the evaporation process in a short time, thereby reducing energy consumption and production costs.
01
Strong applicability
Its unique structural design enables the product to handle materials with high viscosity, particle content, thermal sensitivity, and easy crystallization. At the same time, it has high operational flexibility, stable operating conditions, and low maintenance workload.
02
Low temperature evaporation
Due to the high vacuum maintained inside the evaporator, the boiling point of the processed material is greatly reduced, making it more suitable for low-temperature evaporation of thermosensitive materials.
03
Short stay time
The flow time of the material in the evaporator is extremely short, effectively preventing the decomposition, aggregation, and deterioration of the product during the evaporation process.
04
High degree of automation
Modern rotary thin film evaporators are usually equipped with advanced control systems that can monitor real-time parameters such as vacuum degree and temperature in the evaporator chamber, cooling water flow rate and temperature in the condenser, ensuring stable evaporation process.
05
Product Advantage and Limitation
The working principle of a rotary evaporator is to scrape the liquid material into a thin film shape by rotating a scraper or brush, so that it is evenly distributed on the heating surface of the evaporator. Then, the heating surface heats the liquid material to evaporate. The steam generated during the evaporation process is condensed into a liquid by the condenser, thereby achieving the separation and concentration of the liquid.
◆ Distribution of liquid materials
It scrapes liquid materials into thin films by rotating a scraper or brush, making them evenly distributed on the heating surface of the evaporator. This distribution method increases the heat transfer area between the liquid material and the heating surface, thereby improving the heat transfer efficiency.
At the same time, the movement of the rotating scraper or brush can also promote the flow of liquid materials on the heating surface, further improving the heat transfer effect.
◆ Heating of liquid materials
The heating surface inside the evaporator heats the liquid material to evaporate. The heating method is usually indirect heating, which transfers heat to the liquid material through a heating tube bundle, avoiding direct contact between the liquid material and the heat source, thereby preventing scaling and burning.
At the same time, the temperature of the heated surface can be adjusted according to the properties of the liquid and process requirements to ensure the smooth evaporation process.
◆ Steam condensation
The steam generated during the evaporation process is condensed into a liquid by the condenser, thereby achieving the separation and concentration of the liquid. The condenser is usually cooled by cooling water, which condenses the steam into a liquid and exits the evaporator.
This design enables product to continuously perform evaporation and condensation processes, achieving continuous liquid treatment.
◆ Scraping of solid residues
The rotating scraper or brush inside the product continuously scrapes away the solid residue after evaporation, maintaining the cleanliness and efficient operation of the evaporator. This design can prevent solid residues from accumulating in the evaporator, affecting heat transfer efficiency and evaporation efficiency.
At the same time, regular cleaning of the evaporator can also ensure the normal operation and service life of the equipment.
