METHOD AND SYSTEM FOR DRYING OF MATERIAL CONTAINING WATER Russian patent published in 2013 - IPC F26B7/00 F26B20/00 C05F3/00 

FIELD: agriculture.

SUBSTANCE: method of drying water-containing mass, such as manure, to obtain one final dry product, includes conditioning the air flow to give it the ability to take moisture, creation of the boundary line of mass/air flow to provide the ability to take using the air flow on the specified boundary line, moisture of the water-containing mass, thereby drying it, in which the air flow is heated; the water-containing mass is fed from the reservoir to the separator; the water-containing mass is separated into the fraction with a relatively high content of solids and to the liquid fraction; the fraction with a relatively high content of solids is used for creation of the first static boundary line of mass/air flow; the liquid fraction is used for creation of the second dynamic boundary line of mass/air flow; the air flow is fed to the first static boundary line of mass/air flow to dry the fraction of the water-containing mass with a relatively high content of solids, and then the air flow is fed to the second dynamic boundary line of mass/air flow for preliminary drying the liquid fraction of the water-containing mass; the preliminary dried liquid fraction is fed back into the reservoir; and the preliminary dried liquid fraction is mixed with the water-containing mass in the reservoir; and the dried mass at regular intervals of time is released from the bottom of the first static boundary line of mass/air flow, and the wet mass is added on top of this boundary. The system for drying a water-containing mass, such as manure, comprises a reservoir for water-containing mass, a fan to create air flow; air heating means for conditioning the said air flow; the boundary line of the mass/air flow provided with a reservoir for placing the water-containing mass and providing passing the conditioned air flow through the reservoir for giving the opportunity to the air flow to take moisture from the said mass, at that the system also comprises a pipe for directing the water-containing mass from the reservoir to the separator, the separator for separating the water-containing mass to the liquid fraction substantially free of solids, and to the fraction with a relatively high content of solids; the pipeline to transport the fraction with a relatively high content of solids into the press; the pipeline to transport the fraction with a relatively high content of solids from the press to the first static boundary line of mass/air flow; the press for forming the fraction with a relatively high content of solids; the first static boundary line of mass/air flow for drying the formed fraction of water-containing mass with a relatively high content of solids; the pipeline for supplying the liquid fraction from the separator to the second dynamic boundary line of mass/air flow; the second dynamic boundary line of mass/air flow provided along the process operation after the first static boundary line of mass/air flow for preliminary drying of the liquid fraction of water-containing mass; and the pipeline for supplying the preliminary dried liquid fraction back into the reservoir.

EFFECT: invention enables to obtain dry manure from water-containing mass in operation of the pig farm.
