Overview
Features of VD83 series pilot thin film evaporation equipment: Equipped with an external condenser with a large condensation area, it can better prevent vapor-liquid entrainment compared to short-range distillation. Made of 316Ti stainless steel with high corrosion resistance, the scraper rotor can achieve excellent liquid film turbulence effect and high evaporation efficiency. It can be used for small-scale production with a processing capacity of 5-10 kilograms per hour. The full jacket design can handle high melting point and high viscosity materials. The production efficiency is high and the automation level is high

Compared to short-range distillation, thin film evaporation equipment has its related application areas, such as
- There are more light components in the raw materials that need to be removed, and using a thin film evaporator will result in higher efficiency
- Not requiring too high a vacuum degree, usually in1mbarThe following can achieve separation
- Due to the need for process scaling up, thin film evaporators are more effective in preventing splashing of light components than short-range evaporators, making them suitable for scaling up thin film evaporation processes to pilot or industrial production
Stainless steel evaporators have higher heat transfer efficiency and higher processing capacity per unit area than glass materials,0.1The processing capacity of a square meter evaporator can reach about10Kilograms per hour.
Thin film evaporators can adopt a full jacket design, which ensures that all parts in contact with the material can be heated after entering the evaporator. Suitable for handling high melting point and high viscosity materials.
The thin film evaporator can be used as a reboiler for distillation columns, with good scalability. After modification, it can be transformed into a distillation device using a thin film evaporator as a reboiler, used for separating components with boiling points relatively close to each other.
Both light and heavy components have gear pumps, and samples can be taken simultaneously at the outlet of the gear pump. After weighing separately, key data such as feed rate and distillation ratio of light components can be obtained, which can guide the experimental process at any time. Due to the continuous feeding, the discharge of light and heavy components is also continuous, and there are no restrictions on sampling and discharging under vacuum. Whether the light component is a product or the heavy component is a product, continuous distillation can be carried out.
