THE RESEARCH FINDINGS ON WATER HEATING IN A GRAIN MOLASSES DISINTEGRATOR
According to the strategy presented in the Federal Scientific and Technical Program for Agricultural Development for the period from 2017 to 2025, an increase in agricultural production is stipulated. In the field of feed production, the achievement of the indices announced in the program is possible through the introduction of modern technologies and means for preparing high-quality feeds and feed additives, processing and storing agricultural products. One of the main components of animal feeds is cereal crops. The technology of molasses production from grain containing a large number of easily digestible carbohydrates has been developed. Due to a dramatic reduction in root crop production, this direction is relevant. To reduce energy consumption in disintegrators, shock principle may be used. This principle of destruction is embedded in the disintegrator developed by us which reduces the energy consumption in grain molasses production. One of the stages of molasses production is water heating. The research goal was to study the process of water heating in the developed disintegrator. The research target was the water heating process. The research subject was the design parameters of the impeller, energy and technological performance of the disintegrator. The experiments were carried out on a plant manufactured by the OOO “Doza-Agro”. The influence of the number of impeller blades and heating time on the water temperature and energy consumption was studied. To do this, a multi-level experiment plan was implemented. The number of blades was changed at three levels and the heating time - at six levels. The methods of experiment planning were used to obtain regression models. Through the experiment, the equations were obtained to calculate the water temperature and specific energy consumption in the grain disintegrator depending on the heating time and the number of blades of the disintegrator impeller. It was found that the lowest energy consumption was observed when using an impeller with 12 blades.
