DEVICE FOR DISPOSAL OF ORGANIC WASTES Russian patent published in 2015 - IPC C02F3/28 C02F11/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, food processing industry, as well as to public municipal services. The invention is intended for disinfection and sequential phase, anaerobic decomposition of crushed biological wastes of products of farm animals, birds, human and production wastes of food processing industry with obtaining of biogas and disinfected (from pathogenic microflora, helminth, their eggs and seeds of plants) mineralised organic fertilisers, as well as bio-fodder additives. The device comprises a cylindrical shaped reservoir divided inside with partitions alternately not reaching the top and bottom of the reservoir into the flow chambers of fermentation to produce over each of their pair of separate gas sections, loading and discharge pipes, heaters of substrate and a gas pipeline connected to the gas sections. The cylindrical shaped reservoir has the height equal to its diameter and its volume is divided by coaxial partitions into five coaxial chambers, the volumes of which are respectively equal to 3, 3, 5, 74, 15% of the device volume, and the loading chamber is located in the centre of the device, and the discharge is at the periphery.

EFFECT: invention provides reduction in heat loss, deep temperature pasteurisation of raw material and its hydrolysis at the beginning of the process, the uniform supply of raw material from one chamber to another, minimising dead spots, elimination of the temperature gradients in the volume and, consequently, obtaining biogas and fertilisers of higher quality with identical periods of disposal of raw materials.
