processing steps:
Raw material processing: After cleaning and drying, the tea leaves are crushed to 20-40 mesh, with a material to liquid ratio of 1:30-1:50 (tea: water).
Ultrasonic extraction:
Parameter settings: temperature 50-60 ℃, ultrasonic power 150-3000W, processing time 20-40min;
Equipment requirements: Industrial grade ultrasonic extraction tank, matched with PLC control system, to achieve precise control of temperature, power, and time.
Solid liquid separation: The extract is filtered through a plate and frame filter press, and the filtrate is concentrated under reduced pressure in a concentration tank to obtain a concentrated tea polyphenol solution.
Dry finished product: concentrate is dried by spray or vacuum freeze drying to produce tea polyphenol powder with purity of more than 95%

This machine is used for dynamic extraction of ultrasonic low-temperature . The material undergoes low-temperature repeated reverse circulation flow, repeatedly passing through an ultrasonic generator with high-altitude effect. This device has a higher extraction rate than regular ultrasonic extraction.
1) The equipment has a sophisticated structure and fully utilizes the characteristics of ultrasonic energy gathering generators. Ultrasonic waves directly act on materials, enhancing the mechanical effect of traditional Chinese medicine extraction through ultrasonic waves, cavitation, local high vibration, high impact, and high sound pressure shear, greatly reducing extraction time by more than 4/5 compared to traditional methods, and processing a large amount of raw materials for medicinal herbs.
(2) The ultrasonic extraction equipment and the matching vacuum decompression and concentration equipment can operate independently or in conjunction during the use of the unit.
(3) This equipment optimizes the product structure based on the original dynamic heat reflux extraction unit by integrating a focused ultrasonic generator and a solvent recovery device into this equipment, enabling the production processes of ultrasonic dynamic ultra-low temperature extraction, low-temperature extraction, filtration, solvent recovery, essential oil condensation, etc. to be completed in one step, greatly saving raw materials and working time, and improving work efficiency by 60% to 80% compared to general multifunctional extraction equipment
(4) High conversion rate of raw materials: This equipment utilizes the physical and cavitation effects of ultrasound to promote the breaking or deformation of plant cell tissues. The vibration, acceleration impact, and sound pressure shear equivalent stress between solute particles are strengthened, resulting in the formation of high-temperature and high-pressure local points in the material, which promotes the precipitation of active ingredients in traditional Chinese medicine and increases the extraction rate by up to 45% compared to traditional processes.
(5) Effectively reduce the loss of thermosensitive components. At the same time, the JYT series ultrasonic extraction and membrane concentration unit adopts a titanium alloy focused ultrasonic generator and pneumatic stirring (or mechanical stirring), which allows large volumes of Chinese medicinal materials to fully contact the ultrasonic probe and accelerate the uniform precipitation of active ingredients in the raw materials.
(6) Considering the convenience of extracting drug residues, the extraction part is equipped with a large aperture manhole or hand hole, and is equipped with an internal and external dual filtration system to prevent small drug residues from flowing into the concentration unit.
(7) The equipment has a compact structure and a small footprint, with an actual footprint of around 5-6 square meters.
(8) The extraction of traditional Chinese medicinal materials is not limited by the polarity and molecular weight of the ingredients, and is suitable for the extraction of the vast majority of traditional Chinese medicinal materials and various components; This device is a fully enclosed internal circulation structure, equipped with an oil-water separator, condenser, and cooler, which can be reused multiple times for valuable solvents.
