| FOR DRYING POOL MATERIALS WITH RENEWABLE ENERGY SOURCES
ANNOTATION Currently, there are a large number of territories in the Republic of Kazakhstan that are not connected to centralized networks. Power supply of objects in such territories is a complex task, the solution of which requires significant material costs. The use of microwave technologies is a promising direction in the processing of agricultural products. In the context of the development of farms located at a considerable distance from centralized power supply networks, the development and creation of microwave installations with autonomous power supply is an urgent task. In the context of the development of farms located at a considerable distance from centralized power supply networks, the use of renewable energy sources is the most effective solution. The article discusses the design features of a microwave installation for drying bulk materials, in which the required technological regime is provided by controlling the power of magnetron microwave generators and the speed of movement of the processed products. Key words: conveyor-type microwave unit, microwave dryer, magnetron, power supply system, power control, wind generator, solar panel. Introduction. Microwave dielectric heating makes it possible to effectively implement a wide range of technologies [1]. The main advantages of using microwave heating in thermal processes are due to the peculiarities of its absorption. Microwave energy is converted into heat within the substance, resulting in significant energy savings and reduced process times. The main areas of application of microwave heating are the food, woodworking, rubber, textile, and pharmaceutical industries [2]. A large number of microwave devices are used, in particular, for the heat treatment of agricultural products and foodstuffs, which usually contain a lot of water and therefore absorb microwave energy well [3,4]. The processing of materials using microwave energy shows many promising advantages over conventional heating technologies, such as improved product quality, reduced process control time, energy savings due to higher efficiency, reduced environmental pollution, lower equipment costs and higher installation flexibility [1]. |
