1. Product Overview
The extraction and concentration machine is an integrated device specially designed for Chinese medicine and plant essence extraction. It enables full-process operations such as material soaking, decoction, oil-water separation, and low-temperature concentration, and is widely used in pharmaceutical, food, health product and other industries for small-batch production or R&D trials.

3. Working Principle
•
Extraction Stage: Medicinal materials are added through the hand hole at the top of the extraction tank and soaked with 5–10 times their weight in water. The material pump enables top-to-bottom self-circulation. Steam heating (steam pressure ≤0.05 MPa) is used, and secondary steam is condensed into reflux by a condenser. After cooling, the oil-water mixture is separated by a glass oil-water separator: essential oil is collected from the top discharge valve, and the water phase flows back into the extraction tank. After decoction, the extract is filtered through two-stage filters and transferred to the concentrator.
•
Concentration Stage: The concentrator is heated by steam jacket, and a water ring vacuum pump provides negative pressure (vacuum degree: -0.06 ~ -0.08 MPa), reducing the boiling point of the medicinal liquid to around 60°C for low-temperature concentration. The evaporator is equipped with a scraper agitator (to prevent sticky and charred materials), and secondary steam is condensed into condensate by a tubular condenser for recovery to the extraction tank or direct discharge. When the concentration reaches a specific gravity of 1.1–1.3, the concentrated liquid is discharged from the back.
4. Performance Advantages
•
Low-Temperature Preservation: The vacuum environment lowers the boiling point, avoiding damage to heat-sensitive components (e.g., essential oils, polysaccharides).
•
Anti-Caking Design: The scraper agitator continuously stirs to prevent material from sticking and carbonizing.
•
Visualized Separation: The glass oil-water separator allows direct observation of essential oil stratification, improving separation clarity.
•
Integrated Process: Combines extraction, concentration, and separation, reducing material transfer losses and pollution risks.
5. Operation & Maintenance Guidelines
•
Pre-operation Check: Confirm that steam pressure and compressed air meet standards; close the discharge door and verify no leakage.
•
Feeding Specifications: Light materials (e.g., flowers, leaves) first; heavy materials (e.g., roots, stems) on top to facilitate liquid outflow.
•
Regular Maintenance: Clean the concentrator's tube bundles every week to maintain heating efficiency; open the feeding port and discharge port when not in use to prevent rubber seals from losing elasticity.
•
Safety Note: Strictly prohibit overpressure (≤0.09 MPa); confirm internal pressure is 0 before opening the lid.
6. Application Areas
The extraction and concentration machine is suitable for Chinese medicine decoction piece extraction, plant essential oil separation, functional food raw material concentration, etc., and is especially ideal for laboratory R&D, small-batch customized production, or teaching demonstrations.
