Film Evaporator AYAN-B100 - High vacuum, material less prone to damageIt consists of one or more jacketed cylindrical vessels and a rotating scraper inside the tube. The scraper continuously刮料 onto the heating surface to form a uniform liquid film of consistent thickness, which then moves downward. During this process, the low-boiling-point components are evaporated, while the residue is discharged from the bottom of the evaporator.
Material enters the evaporator diagonally through an inlet located beneath the separator cylinder, and is continuously and evenly distributed along the inner wall of the evaporator cylinder by a distributor installed inside the separator cylinder. The secondary steam evaporated from the evaporator cylinder rises to the separator cylinder, where it is separated from any droplets or foam it may carry by a gas-liquid separator installed within. The secondary steam is then drawn out of the evaporator through an outlet at the top.
Many taboos need to be observed when using a film evaporator, such as strictly prohibiting the operation of the motor stirrer under conditions of no liquid or full liquid; strictly prohibiting reverse operation; and strictly prohibiting touching moving parts during operation. Only in this way can we ensure the safety of both equipment and staff during use.
Additionally, operators must ensure electrical safety by not pressing buttons with wet hands. Please specify if the internal temperature of the equipment exceeds 150 degrees when placing an order to ensure the equipment meets actual production conditions and achieves optimal performance.
After a period of operation, the thin-film evaporator requires maintenance. Typically, its reducer lubricant is 40# engine oil, and the amount of oil should be within the indicated level. Excessive oil can cause stirring and heat generation, while insufficient oil can lead to the destruction of the eccentric shaft pump oil film, causing overheating and temperature rise. Initially, change the lubricating oil twice within the first month of use, and thereafter, replace it every 3-4 months.

Film Evaporator AYAN-B100 - High vacuum, material less prone to damageProduct Features:

Operated at temperatures well below the material's boiling point, with short material dwell times; beneficial for separating high-boiling point, heat-sensitive, and easily oxidizable materials.

2. Effectively removes substances from liquids such as organic solvents and odors, which is a highly effective method for desolvating liquids after solvent extraction.

3. Optional distillation of volatile products to remove other impurities; multi-stage separation allows for simultaneous separation of two or more substances.

4. High vacuum distillation, vacuum degree can reach below 0.1Pa, achieving a high vacuum internally. Typically, molecular distillation operates under very low pressure, hence the material is less prone to oxidation and damage.

5. The distillate film is thin and has high heat transfer efficiency, with a film thickness less than 0.5mm.

6. Higher degree of separation; molecular distillation can separate substances that are conventionally difficult to separate.

7. No boiling or bubbling occurs; molecular distillation is a free evaporation at the liquid surface, carried out under low pressure. There is no dissolved air in the liquid, so the entire liquid cannot be brought to a boil during the distillation process, and no bubbling phenomenon is present.

8. Offer a variety of specifications for customer selection, suitable for small-scale and pilot experiments. Larger evaporation area specifications can be customized according to customer requirements.

9. Physical separation method - non-toxic, harmless, pollution-free, and residue-free, yielding pure and safe products

10. The scraper system is made of PTFE material and SS316L stainless steel, offering excellent corrosion resistance.

11. The feed tank options include pre-heating functionality, with adjustable preheat temperatures.

12. Seals at all interfaces are made with fluorine rubber gaskets, ensuring good airtightness. If the customer requires corrosion resistance, the gaskets can be replaced with PTFE material.
