What is a machine tool?

Machine tool skills were first applied to large-scale industrial removal of plant factors in coffee beans, and later also applied to extract plant factors from tea, the plant factor content in coffee is 0.6%-3%, and the plant factor content in tea is about 1%-5%, the extracted coffee can be used as a medicinal compress, and coffee without plant factors can meet people's needs.

The traditional method selects solvent extraction technology, there are solvent residues, low extraction rate and other problems, the application of supercritical carbon dioxide fluid extraction technology deals with these problems, the purity of the product is greatly improved, carbon dioxide is easy to dissolve, after the extract passes through the separation device, the plant factors are eluted by water, the carbon dioxide continues to circulate, and sometimes activated carbon is used instead of water to elute plant factors.

With the development of skills, the extraction of plant factors has been greatly improved, in the more successful is the semi-continuous production method of General Foods, which is characterized by the fact that when the timing of feeding and discharging, the material will be convection with the solvent in the equipment, so that the concentration of plant factors in the carbon dioxide fluid will be greatly increased, and the extracted non-plant factor components will return to the substance. So the flavor of the extracted coffee is still pure.
