The multifunctional extraction and concentration production line can be used for various process operations such as atmospheric pressure, water decoction, wet soaking, hot reflux, cyclic permeation, aromatic oil extraction, and organic solvent recovery in industries such as medicine and healthcare, pigments, food and beverage, animals and plants, and chemical industry. Compliant with GMP pharmaceutical standards, mainly suitable for laboratory research and development in universities, research institutes, and enterprises, as well as small and medium-sized production lines.
Equipment features:
Has the advantages of high efficiency, easy operation, and high degree of automation; Central controller control, excellent material selection for unit equipment; Adopting dynamic extraction and concentration, with short time and high efficiency; Adopting electric boiler heating method or electric heating method; The tank is equipped with a CIP cleaning device, which can control and display the extraction and concentration temperature, as well as the pH value; Three layer insulation, open structure; 300 mesh polished inner and outer welds, made of SUS304 material.
Working Principle:
Put the medicinal herbs into the extraction tank and add 5-10 times the solvent such as water, ethanol, methanol, acetone, etc. (according to the process requirements). Turn on the heating system of the extraction tank, heat the extraction solution to boiling for 20-30 minutes, and then use a filter tube to draw one-third of the extraction solution into the concentration tank. Close the extraction tank and jacket hot water, turn on the concentration tank and heating system to maintain the temperature of the concentrated juice at around 80 ℃, and keep the vacuum degree at -0.05 to -0.08MPA. The secondary steam generated during concentration is converted into condensate through the condenser and cooler and refluxed to the extraction tank as a new solvent. The new solvent is added to the medicine from top to bottom through the medicinal material layer to the bottom of the extraction tank. The soluble components in the medicinal material are dissolved in the solvent in the extraction tank, and the extracted liquid is drawn into the concentration tank through a filter tube. The secondary steam generated by concentration is then sent to the extraction tank as a new solvent, forming a new solvent reflux extraction. The concentration continues until it is dissolved (the extracted liquid is colorless) and concentrated into the required specific gravity ointment. The colorless liquid in the extraction tank Can be reused next time. If extracted with organic solvents, add an appropriate amount of water first, open the straight tube and jacket hot water, recover the solvent, and discharge the slag.
