Product description

Henan Subcritical company is to provide solutions in the field of bio-processing of plants, animals and microorganisms, and to realize it by turnkey projects.

Currently, we can provide oil pretreatment machine, oil press, subcritical low-temperature extraction equipment, oil refining machine, molecular distillation machine, water extraction and alcohol extraction machine.

subcritical extraction machine

Definition of subcritical extraction technology: solvent in the temperature interval higher than its boiling point but lower than the critical point, under a certain pressure to liquefy the state exists, we define as the solvent's subcritical state. In this state using its similar soluble physical properties, used as a biological component extraction solvent for subcritical extraction solvent, the extraction process is called subcritical extraction process.

The solvents suitable for extraction and desolvation at room temperature and lower temperatures are defined as low-temperature subcritical solvents, and at present there are five types of low-temperature subcritical solvents suitable for industrial production, namely, propane, butane, DME, R134a, and liquid ammonia.

Subcritical extraction technology is an innovative and universal processing technology platform. Summarized in one sentence, subcritical extraction process is a low-temperature, low-pressure, high-efficiency physical method.

Edible oil refining machine

Henan subcritical company can provide plant and animal oil refining machine, such as rice bran oil refining machine, grapeseed oil refining machine, walnut oil refining machine, flaxseed oil refining machine and so on.

Advantages of subcritical extraction technology

Compared with hexane and other conventional solvent extraction process, low-temperature subcritical extraction process has the following outstanding advantages: 

1. the material in the heat-sensitive components of the damage is small, suitable for the extraction of plant components, herbal ingredients extraction; 

2. the loss of volatile essential oils is small, the components of the whole, the taste is pure and suitable for the extraction of essential oils of plants; 

3. energy saving, energy-saving solvent evaporation is less energy-consuming, the desolvation process does not have to make the material warming up; 

4. with a certain degree of selective extraction advantages.

Compared with supercritical carbon dioxide extraction process, low-temperature subcritical extraction process has the advantages of high efficiency, low pressure, as well as the advantages of small investment, low production costs, large production scale.
