What is the function of JC series alcohol precipitation tank
source：www.sjbyj.com Release time：2026-09-22
The JC series alcohol precipitation tank (referred to as the alcohol precipitation tank) is a core specialized equipment for alcohol precipitation and purification processes in the pharmaceutical, health products, food, and chemical industries. It is mainly used for solvent replacement of feed liquids, low-temperature/room temperature settling for impurity removal, and solid-liquid separation, meeting GMP production standards.
1、 Core process function
1. Ethanol precipitation of traditional Chinese medicine extract to remove impurities (the main purpose)
Put the concentrated solution of traditional Chinese medicine decoction into the tank, add ethanol according to the process ratio, and mix thoroughly by stirring; By utilizing the characteristic that impurities such as starch, protein, mucilage, and resin are insoluble in high concentration ethanol, this ineffective group can be analyzed to produce flocculent precipitates; The active ingredients such as alkaloids, flavonoids, and glycosides are dissolved in ethanol to form a supernatant, which separates the active components from impurities, improves the clarity and purity of the extract, and reduces the hygroscopicity of subsequent products. It is a key purification unit for traditional Chinese medicine oral liquids, extracts, and granular preparations.
Can support two processes: ambient temperature alcohol precipitation and cryogenic low-temperature alcohol precipitation; The jacket is filled with frozen saline water for temperature control, and the low-temperature environment can further enhance impurity precipitation and reduce the loss of effective ingredients.
2. Water sedimentation process treatment
In addition to alcohol precipitation, it can be used in reverse for the water precipitation operation of alcohol extraction concentrate. Water is added to the alcohol extraction concentrate to precipitate and settle alcohol soluble impurities, completing secondary purification and achieving dual-use in one tank.
3. Suspension solid-liquid separation
It can be extended to the static settling and crystallization separation of suspended materials in food, biological, and chemical systems, achieving the separation of supernatant and sediment residue.
2、 Supporting function function (implemented by the built-in mechanism of the device)
1. Mixing function
The three bladed stirring system inside the tank achieves uniform mixing of concentrated liquid and ethanol, regulates the alcohol content of the system, avoids local uneven alcohol content causing premature precipitation of effective ingredients, and ensures batch process consistency.
2. Constant temperature control function
The tank is equipped with a jacket and an external insulation structure, which can be filled with cooling water and frozen salt water to cool and insulate the liquid inside the tank, stabilize the settling temperature, control the settling rate, and reduce the degradation of heat sensitive effective substances.
3. Layered discharge and clear liquid extraction
Configure a 360 ° adjustable clear liquid outlet tube, which can extract the upper clear liquid as the liquid level drops, avoiding the suction of sediment at the bottom; The conical bottom of the tank facilitates sedimentation and collection, and the sediment residue can be discharged through the bottom slag discharge valve to reduce material and liquid loss.
4. Process observation and cleaning
Mirrors and light holes are installed on the top of the tank to allow real-time observation of the mixing, settling, and layering status of the material and liquid inside the tank; CIP spray cleaning device can be configured to clean the tank on-site, meeting the requirements of clean production.
5. Explosion proof and sealed safety treatment
The whole machine adopts a sealed tank, explosion-proof drive motor, and mechanical seal. Ethanol is a flammable and explosive solvent, and the sealed structure prevents ethanol evaporation, reduces the risk of workshop explosion, collects volatile solvents, and ensures the safety of alcohol precipitation production.
3、 Downstream value role
The alcohol precipitation supernatant obtained by JC alcohol precipitation tank separation is sent to the subsequent ethanol recovery and concentration process. The recovered ethanol is recycled and reused to obtain high-purity extract, which is used for the preparation of finished products such as oral liquids, mixtures, traditional Chinese medicine granules, and pastes; Concentrated discharge of sediment waste for harmless treatment.
4、 Applicable industries
Production scenarios requiring solvent precipitation and purification, such as traditional Chinese patent medicines and simple preparations, health food, plant extracts, biological products, food ingredients, chemicals, etc.
