METHOD AND DEVICE FOR OBTAINING HAPRIN Russian patent published in 2017 - IPC C12M1/04 C12N1/20 C12N1/26 A23K10/10 

FIELD: chemistry.

SUBSTANCE: method and apparatus for obtaining haprin is proposed. The method is carried out by grinding and homogenizing wood chips, transferring pulp of wood meal to a reactor for wood processing by supercritical technology. The gas produced in the reactor is fed to the fermenter, and in the fermentor on a nutrient medium, a culture of methane-oxidizing microorganisms is grown during aeration. A concentrated solution of haprin is isolated from the culture liquid on the separator, subjected to plasmolysis, followed by isolation of haprin. The device contains a sequentially installed block for pulverization and homogenization of wood meal pulp, a wood processing reactor based on supercritical technology, a fermenter, a separator, a plasmolysis unit, a drying and granulating agent, and a collection of haprin.

EFFECT: simplification of the method and plant for obtaining haprin, as well as production of grapre without natural gas.
