Infrared drying chambers are fit to accomplish this task. The main advantage of the process of drying products with infrared rays is a higher rate of moisture removal in comparison with convective or conductive (contact) drying. Unlike other methods of preservation, infrared drying allows obtaining a final product that retains all the biologically valuable properties and almost all the vitamin elements. The cost of the drying process with an infrared dryer is up to 20% lower than in conveyor- type devices and amounts to 0.9-1.4 kW / h per 1 kg of evaporated moisture. The overall aim of the study is to develop and improve advanced technological processes and experimental technical means for intensifying the drying of plant materials in a cylinder drier, which allows for a significantly accelerated pace of producing high-quality feed additives, improve its quality and reduce the energy and metal consumption of the drying process. The scientific novelty of the work lies in the development of a generalized calculation for drying plants with an infrared heat source. Keywords: drying, humidity, temperature, drying intensity, IR radiation. Download 5.03 Kb. Do'stlaringiz bilan baham: |
