First, the principle and characteristics of supercritical extraction:

Supercritical extraction technology is a new subject of modern chemical separation technology, and it is an advanced separation technology rising in the world at present. Supercritical extraction means that at a certain pressure and appropriate temperature, in the extraction cylinder, the solvent fully contacts with the extracted substance, and the solute diffuses into the solvent, and then the working conditions are changed in the separator to precipitate the dissolved substance, so as to achieve the purpose of separation.

Second, the characteristics of supercritical fluid extraction:

1. The extraction temperature is low, and the product will not be decomposed.

2. By controlling the temperature and pressure, selective extraction can be realized.

3. There is no solvent residue in the product.

4. The solvent can be recycled.

5, no environmental pollution.

Supercritical fluid extraction technology uses CO2 as solvent, which has the following advantages:

1. The supercritical state of CO2 is easy to realize.

2. No toxic pollution to food and medicine.

3. It has the function of preventing bacterial activities.

4, it is not easy to burn and has good chemical stability.

5. Low price and good economy.

Safety system is the most important part of equipment, which is divided into hard safety system and soft safety system.

Hard safety system is a safety control system that can be realized even when the equipment is in the state of no electricity, including safety valve and one-way valve. The extraction kettle and separation kettle are equipped with their own independent safety valves, and the overpressure is automatically released.

The soft safety system consists of integrated circuit safety control, electric contact pressure instruments, pressure and water level alarm safety control, etc. Once the soft safety system is triggered, it needs to solve the problem before it can work normally, and forcibly starting the power device is invalid.
