Herb Extraction Machine
Briefly speaking, the herb extraction machine is the use of extraction method to extract the essential oil or effective ingredients out from herbs. For example, in China, we have so many types of traditional Chinese medicine that are processed via such extractors. Herb Extraction Machine is one of the botanical extractors.
The components of herb extraction machines contain extractors, condensers, coolers, separators, filters, and pneumatic control systems and slag sections. The design and crafting carry out according to the different needs of users. Such herb extraction systems widely use in traditional Chinese medicine, plants, food, biological and chemical industries. atmospheric pressure, compression, decompression, extraction, warm soaking, heat reflux, forced circulation, leakage, aromatic oil separation, and organic solvent recovery.
Herb Extraction Equipment Working Principle
Conventional extraction methods include water boiling, dipping, percolation, reflux, solvent extraction, steam distillation and etc. It is an extraction method that uses the effective ingredients in herbs to be distilled with steam without being destroyed
Water Solvent to Extract
Water and herbs load into the extraction tank; start heating tank jacket. After the tank boils, reduce the heat supply to keep the tank under boiling status yet not overheated. This process goes on for a certain time upon the extraction process. During the closed-loop extraction, chilled water is constantly there to let the steam cooled back into the extraction tank. We repeat and cycle this extraction process to get out effective ingredients as much as possible.
Alcohol Solvent to Extract
First, add grinded herbs and alcohol to the tank, keep the extraction system a closed-loop circulation. The work process is similar to water solvent extraction. In some cases, using alcohol can lower the extraction temperature to protect the heat-sensitive raw material. To reach a lower temperature, a vacuum is also applied constantly. Assisting with a vacuum pump and medicine transfer pump, to get a higher content of effective material mass. When using ethanol, the extraction systems also need an anti-explosion design for operation safety as ethanol is a flammable and explosive solvent. The factory should also have alcohol recycled to avoid environmental pollution. Also by recycle can save extraction costs. When the need to extract the essential oil from herbs, the oil-water separator should be used.
Using Acid Water Extraction Method
Some raw materials need extract under a slightly acidic environment such as pectin extraction. The raw material is usually fruits like orange, apple, tomato and etc. Pulverize the raw material mass first and then add it to the extraction system. Purified water passes through steam to heat up and kill enzymes and remove other impurities. Then washed with water to remove impurities such as pigments and proteins. A decanter centrifugal will filter the extract, the filtered residue needs drying and recycle. The filtrate is then concentrated to a thick paste by falling film evaporator, alcohol precipitation, centrifugal filtration, vacuum drying. The finished product is crushed and packaged for storage. Alcohol precipitation solvent is recovered for use. Our counter current extraction system is suitable for pectin extraction. Welcome for inquiry.
To make extraction more efficient, ultrasonic is introduced into the extraction process due to its physical effect. The ultrasonic extraction makes herb mass and particles interact more with each other. The cavitation can cause the plant cell tissue to break or deform. There is the vibration, acceleration shock, and sound pressure between the particles. That ultrasonic extraction system accelerates the extraction of the effective ingredients in the raw material. It works under room temperature, reducing the loss of heat-sensitive ingredients.
There are also other types of extraction ways using different solvents and suitable for raw material not limited to herbs. For example, Co2 supercritical extractor, butane BHO extraction, acid and etc. The extractor design is quite different from the above-mentioned ones.
Traditional Chinese Medicine Extraction Machine
Traditional Chinese medicine extraction machine is the equipment often used by pharmaceutical manufacturers in the traditional Chinese medicine (shorten as TCM) industry. This equipment derives from plant extraction equipment. The traditional Chinese medicine extraction system is actually more targeted in terms of extraction that meets the chemical characteristics of most Chinese medicines. For relatively rare and precious Chinese medicine, we use specially designed extraction machines. Chinese medicine extraction equipment is not the same concept as plant extraction equipment. Most Chinese medicines extract from plants and herbs, but not limited to just plants. Other raw materials can be from animals and biological sources.
With the awareness of a healthier and sustainable lifestyle, extract pharmaceutical ingredients from Chinese medicinal materials projects becomes popular. extraction equipment is closely related to concentration equipment. When there is extraction, there is usually concentration. The assembly of concentration and extraction together become a concentration extraction machine. Let’s take a look at the Multifunctional Herb Extraction Equipment of R&D size. This is suitable for university, R&D center and trial purposes.
The low-temperature lab extracting and concentrating system consists of an extracting tank, storage tank, condenser, heater, evaporator, oil-water separator, buffer tank, operation platform, cycle pump, vacuum pump, etc. The user can use it in a single unit or multiunit (parallel connection or series connection). Generally, a multiunit can be three units, five units, six units, and seven units. Three-units have three extracting tanks, with three storage tanks& three cycling pumps. Five units are collocating five relevant equipment, so do six units& seven units. Each unit collocates a specially designed heating system and could be controlled automatically by the computer in accordance with different technological processes. In sum, the full system has a convenient and fast operation, small occupation area, convenient cleaning, energy saving& high efficiency.
