The equipment features simple operation and compact footprint. Both the heater and evaporator are wrapped with high-density thermal insulation material, and covered with a stainless steel thin plate shell with mirror or matte surface finish.
For alcohol recovery applications, it delivers strong recovery capacity with a vacuum concentration process. Compared with traditional similar equipment, it increases productivity by 5–10 times and reduces energy consumption by 30%, featuring low investment cost and high recovery efficiency.
Equipment Features
- High-efficiency vacuum concentration Adopting external heating natural circulation paired with vacuum negative pressure evaporation, it achieves fast evaporation speed and high concentration degree, especially suitable for low-temperature concentration of heat-sensitive materials.
- Fully enclosed hygienic design The concentration process operates in a fully sealed state to avoid external contamination. It effectively preserves active ingredients of the liquid, ensuring strong medicinal flavor and high product quality, fully complying with pharmaceutical and food hygiene standards.
- Easy maintenance and cleaning The top and bottom covers of the heater can be opened for quick and thorough cleaning. It is straightforward to operate with small floor space, suitable for workshop layout of different production scales.
- Premium thermal insulation structure The heater and evaporator are insulated with high-density thermal insulation material, and clad with stainless steel sheet shell in mirror or matte finish, which reduces heat loss and presents a neat appearance.
- High-efficiency solvent recovery It delivers excellent alcohol recovery performance via vacuum concentration process. Compared with conventional equipment, it lifts productivity by 5–10 times and cuts energy consumption by 30%, bringing high economic return with low investment.
- Stable and reliable operation Mature structural design ensures stable long-term continuous operation with low maintenance cost, adapting to various batch and continuous production scenarios.
Working Principle
The equipment integrates external heating natural circulation and vacuum negative pressure evaporation technology. Materials are heated by steam inside the tube heater, then rise through the external circulation pipe into the evaporation chamber. Under vacuum negative pressure, the boiling point of the material is reduced, enabling rapid low-temperature evaporation.
The concentrated liquid flows back down to the heater, forming a continuous natural circulation to steadily complete the concentration process. The secondary vapor generated from evaporation enters the condenser to be condensed and recovered, which can be used for alcohol and other solvent recovery. The whole process runs in a fully closed system with no material contamination and high concentration efficiency.
