Problems solved by technology

And these seeds stuck in the upper part of the outer layer of the circular pipe are easy to be overdried due to the long drying time, that is, they are burnt, which affects the quality of the seeds.
[0004] Domestic seed drying equipment mainly includes large-scale fixed tower dryers and fluidized tank dryers. Fixed tower dryers require a large investment and a long cycle. The hot air temperature is high and the drying time is short. It is a short-term rapid heating and drying. It is difficult to guarantee the quality of the grain. The precipitation is small. It needs to be dried twice or multiple times. Moreover, the quality after drying is poor, the energy consumption is high, and it is labor-intensive and time-consuming. , and the seeds are always in motion during the drying process, resulting in a high breakage rate
[0005] However, due to the concentration of seed harvesting time, it is necessary to complete the drying of a large number of seeds in a short period of time. For the existing large-scale seed drying equipment, it still cannot meet this demand. The newly harvested seeds have high humidity and cannot be dried in time. Seeds are prone to germination, causing losses

Abstract

The invention discloses a seed drying system. The seed drying system comprises a pre-storage tower (1), a drying tower (2), a cooling tower (3), a hot air blowing device and two cold air blowers, wherein the pre-storage tower (1), the drying tower (2) and the cooling tower (3) respectively comprise a tower body, a feeding port arranged at the upper part of the tower body, a discharging port arranged at the lower part of the tower body, an air inlet cavity arranged outside the tower body, as well as an air inlet pipe (4) and an air outlet pipe (5) arranged inside the tower body, the lower surfaces of the air inlet pipe (4) and the air outlet pipe (5) have vent holes (6), one end of the air inlet pipe (4) is communicated with the air inlet cavity, the other end of the air inlet pipe (4) is sealed, and two ends of the air outlet pipe (5) are communicated with air outside the tower body. The seed drying system has the beneficial effects of satisfying the requirements on the drying operation of a large number of seeds which needs to be completed in a short period of time during a seed harvesting period, and being high in degree of automation, simple and convenient to operate, small in occupied area, uniform in drying effect and high in heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of seed processing equipment, in particular to a seed drying system. Background technique [0002] In order to increase the shelf life of seeds, it is necessary to reduce the moisture content of the seeds. The existing method is to reduce the moisture content of corn seeds by drying and drying; for the drying method, it takes a long time and is limited by the weather and the site, which is not conducive to mass production. Moisture removal is uneven. At present, some grain depots and grain processing factories in my country have changed from the traditional method of artificial drying to reduce the moisture content of grain seeds to mechanized drying methods. The outstanding advantage of the mechanized drying method is that it is not restricted by natural conditions, can work around the clock, and has a large drying batch and high work efficiency. However, the heating raw materials of the drying equipment ...
