Technological process and design features of vibrating seed dryers
Drying of materials is a complex technological process used in various industries and is often one of the main stages of production. This process, in particular for bulk materials, depends on humidity, particle size, hydrodynamic conditions of the particles flowing through the drying agent and environmental parameters. Grain dryers expose grain to harsher conditions than natural drying, which can potentially lead to a deterioration in grain quality. The combination of these factors determines the nature of the entire process. In agricultural production, the drying stage is one of the most important for grain preservation. Currently, the convective drying method is widely used for this process. However, along with its advantages, this method also has a number of significant disadvantages, one of the most important of which is its high energy consumption. In this regard, scientific research is being intensively conducted to develop ways and methods to reduce the energy intensity of the convective drying method. The effects of vibration on raw materials are being rapidly introduced in various industries. The use of vibration technologies during drying intensifies the process of processing grain raw materials due to the rapid renewal of its surface in contact with the drying agent. Fast and efficient drying with vibration technology reduces moisture content and the risk of fungi and mold in the grain. The construction of the dryer using vibration technology helps to avoid overheating of the grain, providing optimal temperature conditions, which contributes to the preservation of nutrients and other useful properties of bulk agricultural materials.
