Product Details
Product Introduction
The conical extraction vessel is primarily used in process operations such as atmospheric- and low-pressure water decoction, warm infusion, hot reflux, forced circulation, percolation, aromatic oil extraction, and organic solvent recovery for traditional Chinese medicine, plant‑based, and animal‑derived materials. Its conical design features a large vessel diameter, a relatively small slag discharge port, excellent sealing performance, reduced material dispersion during discharge, and easy collection of the extracted product.
Accessory components
The conical extraction vessel can be equipped with a condenser, cooler, oil–water separator, foam trap, filter, and medicinal‑liquid pump. The oil–water separator is specifically designed for alcohol‑based extractions to recover oil. Depending on the customer’s process requirements, the extraction vessel can be fitted with an agitator system; an internal mechanical stirrer is installed to induce motion of the feedstock during extraction, accelerating mixing and effectively preventing low‑density extracts from floating on the solvent surface and resulting in inadequate penetration. This enhances extraction efficiency and reduces extraction time.
Working principle
The entire extraction process in the extraction vessel is carried out within a closed, recirculating system, allowing for both atmospheric-pressure and low-pressure extraction. Depending on the application—whether water extraction, alcohol extraction, oil extraction, or other uses—the specific process parameters are determined by the customer based on the pharmacological properties of the target compound.
1. Water extraction: Water and the traditional Chinese medicine are loaded into the extraction vessel according to a specified process ratio. The jacketed heating source is then activated; once the contents in the vessel reach boiling, the heat supply is reduced to maintain gentle simmering. The extraction is carried out for an appropriate duration based on the pharmacological extraction protocol, ensuring that the active constituents of the herbal material or sliced herbs are fully dissolved in water.
2. Alcohol Extraction: First, the medicinal materials and alcohol are added to the vessel according to a specified process ratio, and the system is sealed. A jacketed heating source is applied; once the desired temperature inside the vessel is reached, the heat supply is reduced to maintain that temperature for a set period, ensuring that the active constituents of the traditional Chinese medicine or herbal slices are fully dissolved into the alcohol. The vaporized alcohol is condensed in a condenser, converted back into liquid form, and returned to the storage tank for subsequent distillation and purification. To enhance efficiency, a pump can be used for forced circulation: the liquid extract is drawn from the bottom of the vessel by the pump and then recirculated back into the vessel through an upper inlet.
3. Oil Extraction: First, the traditional Chinese medicine containing volatile oils and water are added to the extraction vessel according to a specified process ratio. Steam is introduced into the jacketed heating system; once the desired volatilization temperature is reached, the steam flow rate is adjusted, and the internal temperature is maintained for a prescribed duration as per the process requirements. The evaporated aromatic oils are then cooled via a cooling system, and the cooled herbal extract is separated using an oil–water separator.
Product Applications
1. Biopharmaceuticals: extraction, percolation, dissolution, and purification of active constituents from traditional Chinese medicine;
2. Food: purification of hops and vegetable/animal oils, extraction of plant pigments, extraction of bioactive plant compounds, and extraction of flavors and fragrances;
3. Cosmetics: extraction, purification, and isolation of cosmetic raw materials;
4. Chemical Industry: recovery of reaction feedstocks, dissolution of organic solvents, and purification.
