Study of the process of heating water in the plant for the preparation of grain molasses

Abstract

Abstract In the Russian Federation, grain molasses is gaining wide popularity when feeding farm animals. Developed technologies for its preparation include the process of heating water. Existing installations for the production of grain molasses conduct water heating in the pump due to cavitations. We proposed to use a passive chopper to speed up the process of preparing molasses and improve its quality. The article presents the description of the installation, methods of research and results of water heating in the installation. The influence of the following factors on the heating rate and power consumption was studied: distance from the nozzle to the grate, the angle of inclination of the grate. The assessment of the working process of the plant was carried out by the rate of water heating and the specific cost of electricity for its heating. As a result of research optimum parameters of the passive chopper at which heating occurs faster and with smaller expenses of the electric power are revealed. The studies of water heating in the plant for the preparation of grain molasses allow us to conclude about the possibility of intensification of the process and reducing energy costs for its implementation by changing the parameters of the grid installation. In this case, preference is given to the heating method with the use of an angled grille.
