The invention relates to a two-stage solution dehumidification grain in-granary drying system, and belongs to the technical field of grain ventilation drying. The system comprises a granary ventilation system, a primary solution dehumidification cycle, a primary refrigeration cycle, a secondary solution dehumidification cycle and a secondary refrigeration cycle. Fresh air is dehumidified by a primary solution dehumidifier and then enters a secondary solution dehumidifier for further dehumidification, dehumidified air enters an evaporator for cooling, and obtained low-temperature dry air is sent to a granary to dry high-moisture grain. When dehumidification drying is needed in the grain storage process, only the secondary solution dehumidification cycle and the secondary refrigeration cycleare started. In the system, the heat of condensation is utilized as driving energy of solution regenerators, and thus the energy saving effect of the system is significant. In addition, the system adopts two stages of independent solution dehumidification cycles, dehumidification cycle stage control is conducted according to the moisture of grain in the granary, and thus the operating efficiencyof the system is higher.
Description
technical field [0001] The invention relates to the field of grain ventilation and drying, in particular to a two-stage solution dehumidification type grain storage drying system. Background technique [0002] Grain drying is one of the important links to achieve safe storage. In my country, the grain loss caused by grain mildew and other reasons is huge every year. How to reduce post-harvest food loss has become a daunting task. In addition, in recent years, there has been a phenomenon that farmers do not dry and sell on the spot after harvesting mechanically, which leads to high moisture content in the purchased grain. In order to ensure the safe storage of grain, it must be properly dried. However, the existing drying methods, such as drying with a dryer, consume a large amount of fossil energy and are costly. Naturally ventilated drying takes a long time and is subject to External environmental weather factors have a great influence. Solution dehumidification is a met...
