The principle of the multifunctional extraction tank

The multifunctional extraction tank is widely used in the pharmaceutical and chemical industries, especially for extracting components from plant-based materials. Its operation varies depending on the extraction method:

1. **Water Extraction**: Water and medicinal herbs are placed in the tank, and the heat source in the interlayer is activated. Once boiling begins, the heat is reduced to maintain a steady boil for a duration determined by the extraction process. If a closed system is used, cooling water is circulated to condense steam and return it to the tank for continuous operation.

2. **Alcohol Extraction**: Medicinal materials and alcohol are added to the tank, which is sealed. Steam heats the interlayer, and cooling water is supplied to condense the vaporized alcohol. For improved efficiency, a pump can circulate the liquid by drawing it from the tank's bottom and returning it to the top, preventing localized channeling.

3. **Oil Extraction**: Volatile oil-containing herbs and water are loaded into the tank. The oil separator's circulation valve is opened, and the heat source is activated. Once the desired volatilization temperature is reached, cooling
