Abstract

The article considers the problems of raising the efficiency of energy resources spent on the operation of a horizontal industrial autoclave, improving the quality of sterilized products and reducing the number of spoiled products. The analysis of the problems in automation control systems has been carried out and the shortcomings of the automatic control systems of technological process of canned food sterilization have been revealed. There has been described in detail the hierarchical structure of the autoclave control system. The main blockages caused by the pressure drop in air-main, water-main and steam-main are indicated. A detailed description of the cooling tower structure is given, the principle of cooling the circulating water and its supply to the consumer is analyzed. Within the framework of solving the problem of increasing the efficiency of energy resources and based on the technical characteristics, throughput and heat transfer coefficient, it is proposed to use 
 a plate heat exchanger. There is described its operation principle, which includes heating the incoming water to a predetermined temperature and cooling it at the end of the sterilization cycle. The combined use of a cooling tower and a heat exchanger will help to greatly reduce the energy costs, because the water used in the sterilization process will not drain into the general sewer at the end of the process, but will be cooled in a cooling tower and supplied to cool the autoclaves. When heated, the live steam won’t go directly into the autoclave, but will be fed into a heat exchanger to heat the circulating water, which will significantly reduce the overheating of the sterilized product
