REACTOR MATERIAL FEED METHOD AND DEVICE Russian patent published in 2015 - IPC D21B1/12 

FIELD: power industry.

SUBSTANCE: this invention relates to a method and device for feeding and dehydration of biomass with possibility of controlling water content in biomass before dehydrated biomass is fed to a reactor for heat treatment and further fermentation. A device for manufacture of bioproducts from biomass includes a feed device and a reactor; with that, the feed device is intended for feeding biomass contained in liquid to the reactor. The feed device includes an external housing, a tank enclosed in the external housing, in which there is an inlet hole for material, through which biomass is fed to the tank, and an outlet hole for material, through which biomass is fed to the reactor. Besides, the device includes a unit for creation of increased pressure to create pressure inside the external housing and for the above biomass inside the tank to be contained at increased pressure, a movement device for moving biomass from the inlet hole for material to the outlet hole for material to feed material to the reactor, which is placed inside the tank, a dehydration device of biomass to be supplied to the reactor, an outlet liquid hole intended to discharge the liquid from the tank. Feeding and dehydration is performed under pressure that is higher than or equal to pressure inside the reactor.

EFFECT: providing air-tightness of a reactor and simplifying material feeding to the reactor in a continuous mode.
