Preparing feed granules, briquets and dried fruits using geothermal water

The purpose of research is to find a method for drying and storing grain, feed briquettes and granules with the lowest energy consumption. The objective of research is to carry out a comparative analysis of energy costs when drying plant products in the most common drying units and the proposed method using thermal water. The implementation of our proposed method of drying grain occurs when using underfloor water heating using thermal water as thermal energy, the temperature of which at the outlet is 87-90 °C. When passing through pipes laid in the floor, the thermal water heats and dries the grain. Underfloor water heating, which helps to dry grain, provides for laying the floor using a concrete screed, the height of which is at least 80-100 mm. If necessary, it is possible to use various types of tedders. In the proposed version, drying of hay and hay flour is allowed. When implementing the method of blanching and drying, the fruits are first scalded for 3-5 minutes with thermal water, the temperature of which at the outlet is 89-92 °C. Then the raw fruits come to the surface of the warm water floor, the thermal energy of which is the same thermal water. Uniform drying of the fruit takes place under the influence of heat emanating from the pipes through which the thermal water flows. It was revealed that, in comparison with the most modern and economical grain dryers in terms of energy consumption, the use of thermal water as thermal energy of an underfloor heating water floor is one of the most energy- and resource-saving methods for drying grain, fruits and various types of juicy feed, on the basis of which patented methods numbered: 1) RU 2 728 590 C1 "Method of drying grain"; 2) RU 2 731 580 C1 "Method of blanching and drying fruits". The invention can be used in the food industry and agriculture.
