An obligatory link in the transfer of products from the producer to the consumer is transport, which must ensure the transfer of products without damage, with the maximum preservation of its quality. From this point of view, vehicles for the transportation of agricultural and food products attract special attention, since these products are easily exposed to pressure, temperature and mechanical damage. One of the most important ways to preserve the quality of products during transportation is the use of vehicles equipped with various types of refrigeration devices. For this, it becomes necessary to develop new vehicles that will be equipped with economical, highly efficient and acceptable refrigeration devices. A schematic diagram of a vehicle equipped with an absorption-type refrigeration machine, which is completely powered by the heat of the vehicle's exhaust gases, is presented. R

In winemaking, the operation of crushing grapes is of great importance, because the quality of the resulting product largely depends on its correct implementation. In order to maximize the preservation of the quality of raw materials during crushing, a schematic diagram of a new device is presented, which ensures the processing of raw materials in the absence of contact with the surrounding air and minimal mechanical damage. The presented device can be installed on a car body to carry out the process of crushing grapes during their transportation from the vineyard to the winery. This ensures a reduction in the duration of the technological process of processing at the winery and the beginning of processing of raw materials as soon as possible after collection.
