PHYSICAL SIMULATION MODEL FOR COMPOSTING RESEARCH Russian patent published in 2022 - IPC C05F17/90 C05F17/60 C05F17/70 G09B23/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. Disclosed is a physical simulation model for studying composting, containing a body equipped with a heating jacket and communicated with a blower through an air duct, an electronic device for input, processing, output and storage of information, a temperature meter-regulator, an air flow rate meter-regulator and a gas analyzer equipped with oxygen sensors, carbon dioxide, ammonia, hydrogen sulfide and methane, the temperature meter-regulator is connected to the heating jacket temperature measurement sensor, the blower has an electric drive with a frequency converter and is equipped with an air flow rate sensor connected to the air flow rate meter-regulator. At the same time, the housing is mounted on electronic scales and additionally contains a removable cylindrical reaction chamber made of heat-conducting material with a double perforated bottom and an air duct connected to the cavity of the double bottom, connected to a blower, and a temperature sensor is installed inside the reaction chamber, connected to a temperature meter-controller, which has the function of equalizing the temperature of the heating jacket with the temperature inside the reaction chamber, while the air duct is equipped with a removable solid-phase microextraction device and a filter-moisture separator connected to the condensate return device to the reaction chamber, and the electronic device for input, processing, output and storage of information is equipped with electronic communication channels with a temperature meter-regulator, an air flow rate meter-regulator, a gas analyzer and electronic scales.

EFFECT: invention provides an increase in the efficiency of studies and the reliability of the results obtained when composting highly heterogeneous organic materials with a dry matter content of more than 20% (wt.) due to the sufficiently high accuracy of maintaining the self-heating mode and eliminating the need to increase the volume of the material under study and the size of the installation.
