What should I pay attention to when operating the extraction concentrator?

The extraction concentrator is a combination unit of extraction and concentration, which is suitable for the extraction, concentration, paste collection, diafiltration, volatile oil extraction, alcohol recovery and other functions of heat-sensitive materials such as plants, animals, traditional Chinese medicines, and food additives, and meets the requirements
of scientific research institutions and hospitals as new drug extraction, new process technical parameter determination, pilot test, new variety development, extraction of precious medicinal materials, and concentration of pharmaceutical liquid.
Short extraction and concentration time and high efficiency; The equipment adopts electric heating and has a high
degree of automation.
The tank is equipped with a CIP cleaning head, which meets GMP medical standards
.
This equipment is mainly suitable for laboratory research and development of universities, scientific research institutes, enterprises and institutions, as well as small and medium-sized pilot production lines
.
It is suitable for atmospheric pressure, micro pressure, frying, warm immersion, hot reflux, infiltration, aromatic oil component extraction and organic solvent recovery in traditional Chinese medicine, plants, animals, food, beverage, chemical and other industries
.
Do you know what to look out for when operating the extraction concentrator? 1.
According to the concentration of the solution, determine the time
to start reflux.
If the reflux time is too early, a low concentration of extract will prolong the effective extraction time
.
If the reflux time is too late, the saturation concentration of the extract is not conducive to the extraction of the active ingredient, and energy is wasted
.
After extraction (boiling) for 1 h, part of the solution should be placed in a concentration tank, reflux should begin and timed
.
Note that the air in the extraction tank should be excluded when boiling in the tank, otherwise pressure
will be generated in the tank.
2.
Before use, ensure that all connecting nozzles are well sealed, all valves open normally, and the liquid outlet is firmly locked
.
3.
Determine the extraction and concentration time
.
Excessive extraction increases impurities in the extract, making later separation more difficult
.
If the time is too short, the extraction is not complete and the raw material is wasted (the concentration of the solution needs to be checked during the extraction process).

4.
The temperature of the reflux liquid should be controlled and not too low
.
At the same time, the temperature in the extraction tank of the extraction concentrator should be controlled and the temperature should be kept as constant as
possible.
Cold extraction has less impurities, good clarity, high thermal extraction efficiency and poor
clarity.
The purpose of boiling is to enhance the diffusion and penetration
of the solution.
Although boiling can reduce the concentration difference of the solution in a short time, it will dissolve many macromolecular impurities
