300L herbal extraction unit

Equipment Introduction
Herbal extraction concentration equipment/herbal extraction unit is an integrated system used for efficient separation and purification of active ingredients from Chinese herbs or plants, typically consisting of four modules: extraction, filtration, concentration, and solvent recovery.
Core components: extraction tank, condenser, evaporator, oil-water separator, storage tank, vacuum system, etc.
Working principle: Effective ingredients are released through techniques such as heating, solvent permeation, and ultrasonic wall breaking, and then the target substance is enriched through vacuum low-temperature concentration.

Applicable scenario: traditional Chinese patent medicines and simple preparations production, essential oil extraction, health care product research and development, laboratory pilot/pilot test

extraction advantage:
Using ultrasonic assisted technology, the extraction rate of cells can be increased by 50% -500% compared to traditional processes by breaking through the wall through cavitation effect.
Hot reflux cycle design: Extraction and concentration are carried out simultaneously, and the solvent can be recycled to reduce raw materials and energy consumption.
Ingredient activity retention:
Vacuum low-temperature concentration (-0.05~-0.09 MPa) avoids the decomposition of thermosensitive components and ensures drug efficacy.
Set up isolation gaps between the heating layer and the medicinal herbs to prevent local overheating and coking.
Convenient operation and safety:
Modular design supports multifunctional switching (water extraction, alcohol extraction, percolation, etc.).
The fully enclosed process reduces solvent evaporation, complies with GMP standards, and reduces pollution risks.
Economy:
Small devices (such as 20L-100L) occupy only 1-4 square meters and are suitable for laboratories and small to medium-sized production.
Solvent recovery system reduces costs by over 30%

Typical process flow
Taking dynamic hot reflux extraction and concentration as an example:
Preprocessing: Grind the medicinal herbs and load them into an extraction tank (with a filter basket).
Extraction stage:
Add solvent (water/ethanol) → Heat (thermal oil or steam) → Start stirring or ultrasound assisted.
The volatile oil components are recovered through a condenser and oil-water separator.
Concentrate and purify:
Extract the liquid and transfer it to a concentration tank → vacuum evaporation (40-60 ℃) → concentrate it to the target specific gravity (1.1-1.4).
The solvent vapor is condensed and refluxed to the extraction tank for recycling.
Post processing:
Electric lifting of drug residue discharge → collection or drying of concentrated solution.
Special process options:
Soxhlet extraction: suitable for small batch high-purity extraction.
Double effect evaporation: secondary steam reuse, saving 50% energy

Application field
Pharmaceutical industry:
Production of traditional Chinese patent medicines and simple preparations extracts (such as EGB761, the standardized extract of ginkgo biloba leaves).
The hospital preparation room prepares decoctions and oral liquids.
Cosmetics and essential oils:
Extract essential oils from plants such as roses and mint, with a purity that meets food grade standards.
Food and health products:
Tea polyphenols, fruit and vegetable juice concentration, and functional ingredient extraction (such as glycyrrhizic acid).
Research and Environmental Protection:
Research on active ingredients of medicinal herbs in universities;
Resource utilization of medicinal residues (e.g. extraction residue to produce succinic acid)
