Laboratory extraction concentratorProduct Introduction

This device is suitable for plant herbs, traditional Chinese medicine, animal medicine, food additives, etc. Extraction using water, ethanol, methanol, acetone, and recovery and concentration using organic solvents.

Laboratory extraction concentratorworking principle:

Put the medicinal herbs into the extraction tank, add 5-10 times the solvent of the herbs such as water, ethanol, methanol, acetone, etc. (according to the process requirements), open the straight through and jacket steam valves of the extraction tank, heat the extraction solution to boiling for 20-30 minutes, and then use a filter tube to draw 1/3 of the extraction solution into the concentrator. Close the extraction tank and jacket steam, open the heater valve to concentrate the liquid material, generate secondary steam during concentration, and send it to the extraction tank through the evaporator riser as the heat source and solution for extraction, maintaining boiling inside the extraction tank. .
The secondary steam continues to rise and is condensed into a hot condensate by the condenser. It then falls back into the extraction tank and is added as a new solvent onto the medicine surface. The new solvent passes through the medicinal layer at high speed from top to bottom and reaches the bottom of the extraction tank. The soluble active ingredients in the medicinal materials dissolve in the solvent inside the extraction tank. The extraction liquid is drawn into the concentrator through a filtration tube, and the secondary steam generated by concentration is sent to the extraction tank as a heat source and new solvent. The new solvent formed in this way is subjected to large reflux extraction. Therefore, the solute density in the medicinal materials is kept at a high gradient with the solute density in the solvent, and the solutes in the medicinal materials are rapidly dissolved until * dissolution (the extraction liquid is colorless). At this point, the extraction liquid stops being drawn into the concentrator, and the concentrated secondary steam is transferred to the cooler. The concentration continues until it is concentrated into the ointment with the required specific gravity (1.2-1.34) and released for use. The colorless liquid in the extraction tank can be placed in the storage tank for the next batch of use, and the medicinal residue is discharged from the slag discharge door. If organic solvent is used for extraction, an appropriate amount of water is added first, and the straight through and clamp are After steam extraction and solvent recovery, the slag is discharged.

Equipment features

1. The yield of the ointment is 10-15% higher than that of the multifunctional extraction tank, and the ointment contains more than twice as many active ingredients. During the extraction process, the hot solvent is continuously added to the medicine surface and passes through the medicine layer at high speed from top to bottom, dissolving the solute in the medicine. The solute content in the medicine maintains a high gradient with the solute content in the solvent, and the solute in the medicine dissolves at high speed until * is dissolved. Therefore, the effective ingredient extraction rate is high, and the concentration is completed in a set of sealed equipment with minimal loss and high conversion rate. Therefore, the yield of the ointment is high and the effective ingredient content in the ointment is high. .
Due to the high-speed dissolution of solutes, short extraction time, and synchronous concentration and extraction, it only takes 7-8 hours for medicinal materials to be concentrated into ointment, resulting in high equipment utilization. .
3. The equipment is single, occupies a small area, and has a high utilization rate, so the investment is low. .
4. Only one solvent is added for extraction, and it is recycled in a sealed device. The solvent in the medicine residue can be basically recovered, so the amount of solvent used is more than 30% less than that in a multifunctional extraction tank, and the consumption rate can be reduced by 50-70%. This paves the way for the extraction and purification of active ingredients in traditional Chinese medicine using organic solvents
5. Due to the use of concentrated secondary steam as the heat source for extraction, the extraction solution drawn into the concentrator is at the same temperature as the concentration, which can save more than 50% of the steam used. The operation is very simple and reduces the number of operators.
