Description
Technical Field
The utility model relates to grain stoving technical field especially involves a microwave hot air drying supply system.
Background
The existing dryers are usually designed to heat ambient air to a suitable temperature by a hot-blast stove or an air-source heat pump, and the heated air is delivered to a drying chamber to perform dehumidification and drying treatment on articles (such as grains) to be dried.
Grains including seeds usually have special requirements on drying, for example, in order to ensure the quality of the seeds, the influence of various factors on the germination of the seeds in the drying process must be fully considered, and the drying time, the control of the highest temperature, the water absorption amount and the like are mainly included.
Experiments prove that the seeds are dried within 12 hours generally (15 hours in actual operation). Taking the conditions of germination temperature and humidity of rice seeds as an example: the lowest temperature is generally 10-12 ℃, the optimum temperature is 28-32 ℃, and the highest temperature is about 40 ℃. When the temperature is as high as 42 ℃ for a long time, the cytoplasm of the seed bud stops flowing, so that the seed bud is burnt, and the quality of the seed is seriously damaged.
The minimum water uptake required for germination of rice seeds is 15% to 18%, i.e. about 60% of the saturated water uptake of the seeds, but in this case the germination is slow and irregular. The best effect is that the seeds are soaked to a saturation degree and are kept for about 35 hours at the water temperature of 30 ℃, and the germination condition of the seeds obtained in the process is good. Therefore, the water content of the seeds stored in the warehouse should be controlled below 12.0% to improve the storage stability of the seeds. For example, the national mandated quality standards for hybrid rice seeds are: the purity is more than or equal to 96 percent, the purity is more than or equal to 98 percent, the water content is less than or equal to 13.0 percent, and the germination percentage is more than or equal to 80 percent.
However, in high-temperature and hot and humid areas, because the humidity of the ambient air is very high, if the ambient air is directly heated and conveyed to the drying chamber, the ideal grain dehumidification effect cannot be achieved. In particular, in the process of drying crop seeds, in order to ensure the vitality of embryos, dry air heat energy drying equipment with low humidity and low temperature hot air is generally needed, the equipment is generally hot air furnace equipment, fuel oil, firewood, coal or other combustible materials are used as fuels, the fluctuation of heat supply temperature is large, the vitality of the embryos of the seeds is reduced if the temperature is too high, and the germination rate is less than or equal to 80 percent, and in addition, in the process of manual operation, the furnace storage time in the process of drying the seeds is not properly controlled, and the seeds are scrapped if the time is too long; and the energy of the equipment is not recycled, the consumption is high, the drying cost is high, and the environment is polluted. And the service life of the hot blast stove is only 2-3 years, so that the hot blast stove has no economic feasibility and needs an excellent alternative scheme urgently.
