The moisture content of the seeds is the percentage of the weight of water contained in the seeds (free water and bound water) to the weight of the seeds. The calculation method of the seed water content in the initial drying stage of the seed is to measure the quality difference of the seed before and after drying, which is the water content. In the same way, the real-time water content of seeds is based on the weight change of seeds before and after a period of time. The period of time here is used as the measurement period, not limited to 1s, 5s or 10s.

The ventilation assembly in the present invention includes: a tertiary injection unit 2, an air supply unit connected to the input end of the tertiary injection unit 2, a micro-explosion unit 3 and a humidity control assembly.

As shown in FIG. 3 , it shows a schematic structural diagram of the three-stage injection unit 2 in the present invention. The input end of the three-stage injection unit 2 in the present invention is provided with a main port 24 , a secondary flow port 25 and a circulation port 26 , and the output end of the three-stage ejection unit 2 is connected to the inside of the chamber body 1 . The main port 24 is connected to the micro-explosion unit 3, and a valve is arranged between the main port 24 and the micro-explosion unit 3, the secondary port 25 is connected to the air supply unit, and the circulation port 26 is connected to the humidity control assembly.

The opening diameters of the main orifice 24, the secondary orifice 25 and the circulation orifice 26 decrease successively, the diameter of the main orifice 24 is 60-100mm, the diameter of the secondary orifice 25 is 40-60mm, and the diameter of the circulation orifice 26 is 10-30mm.

The present invention provides a structural schematic diagram of a three-stage injection unit 2 . The three-stage injection unit 2 includes: a housing, a first nozzle 21 and a second nozzle 22 arranged inside the housing, a first mixing chamber arranged between the first nozzle 21 and the second nozzle 22, The second mixing chamber communicated with the second nozzle 22, and the diffuser chamber 23 connected with the second mixing chamber. The input end of the first nozzle 21 communicates with the main port 24 , the housing located at the position of the first mixing chamber is connected with the secondary port 25 in the circumferential direction, and the housing located at the position of the second mixing chamber is connected with the circulation port 26 in the circumferential direction. The diffuser chamber 23 here is a structure in which the expansion pressure gradually increases along the axial direction of the throat diameter of the mixing chamber.

In the present invention, the micro-explosion unit 3 is used to generate high-temperature, high-pressure and high-flow gas, the gas supply unit is used to generate low-temperature, low-pressure and low-flow gas; the humidity control component is used to directly introduce or dry the gas inside the warehouse body 1 Then it is introduced into the circulation port 26 of the three-stage injection unit 2.

It should be noted that here, high temperature, high pressure and high flow are relative concepts to low temperature, low pressure and low flow, which means that the gas generated by the micro-explosion unit 3 is greater than the temperature, pressure and flow of the gas supply unit. Due to the gas source of the circulation port 26 and the inside of the chamber body 1, its temperature, pressure and flow rate are all lower than the gas supply unit.

In the present invention, the working principle of the three-stage injection unit 2 in the initial seed drying stage is: the gas with high temperature, high pressure and high flow rate generated by the micro-explosion unit 3 enters the main port 24 and the first nozzle 21, and passes through the first nozzle. The tube 21 sprays toward the center of the first mixing chamber, while entraining and mixing the low-temperature, low-pressure, and low-flow gas in the secondary flow port 25 . The mixed gas enters the second nozzle 22 as the "main fluid", sprays to the center of the second mixing chamber through the second nozzle 22, and simultaneously entrains and mixes the gas in the circulation port 26; The mixed heat transfer, uniform velocity and pressure in the second mixing chamber are sent to the diffuser chamber 23 and then enter the interior of the chamber body 1 after being diffused.

The present invention utilizes the high-pressure and high-flow gas generated by the micro-explosion unit 3 to inject relatively low-pressure gas to realize the pressurization, heat transfer and flow increase of the low-pressure gas, that is, to realize the pressurization, heat transfer and increase of the carbon dioxide gas. stream, which increases the drying rate of wheat seeds.

The gas at the output end of the three-stage injection unit 2 in the present invention directly acts on the surface of the seed, the heat in the gas is transferred to the surface of the seed, and then transferred from the surface to the inside of the seed, forming a process of heat transfer, while the free water in the seed is transferred from The interior diffuses to the surface of the seeds in a gaseous state, and diffuses from the surface of the seeds to the hot gas in the environment of the chamber body 1 through the gas film, thereby reducing the water content of the seeds.

The energy release assembly in the present invention includes an elastic unit 4 and an anti-spark device arranged on each shelf 11 . The elastic unit 4 communicates with the blasting assembly through the pipeline, and the kinetic energy of the high-pressure gas generated by the micro-explosion unit 3 acts on the elastic unit 4 through the pipeline, so that the elastic potential energy compressed by the elastic unit 4 is released, and then it is stacked on the warehouse rack 11. Wheat seeds are vibrated.

The elastic unit 4 in the present invention is not limited to the use of buffer airbags, the expansion of the buffer airbags filled with high-pressure gas makes the seeds jump on the warehouse rack 11, increasing the contact area between the seeds and the gas at the output end of the three-stage ejection unit 2 , which is conducive to the reduction of seed water content.

The buffer airbag in the present invention is a composite material, which consists of a high-temperature resistant layer, a rubber layer, a high-elasticity layer and a contact layer in sequence from inside to outside. The high temperature resistant layer is a high temperature resistant mineral wool layer to protect the rubber layer and the high elastic layer. The rubber layer is a polymer material with reversible deformation, which is full of elasticity, can produce large deformation under the action of external force, and can quickly return to its original shape after the external force is removed. Here, the rubber layer is preferably a kind of natural rubber or butadiene rubber. The high elastic layer is made of polyester elastomer material, propylene-based elastomer material and fluorosilicon polymer material. The propylene-based elastomer material is arranged outside the polyester elastomer material, and the fluorosilicon polymer material is arranged outside the propylene-based elastomer material. The function of the high elastic layer is to further increase the deformability and strength of the rubber layer. The contact layer in the present invention is in direct contact with the wheat seeds, and the contact layer is made of synthetic rubber and nano-boron fibers, which can significantly improve the wear resistance and strength of the contact layer and improve the service life of the buffer airbag.

In the present invention, the buffer air bag is used to vibrate and separate the seeds, which is softer and less likely to damage the seeds compared with the mechanical stirring method in the prior art.

In the present invention, the micro-explosion unit 3 includes: a micro-explosion chamber, an air storage tank and an air filter connected to the micro-explosion chamber, and an ignition electrode arranged inside the micro-explosion chamber; Shooting unit 2.

Micro-explosive gas is stored in the air storage tank, and the air filter is used to filter dust particles in the air to reduce incomplete combustion when the micro-explosive gas reacts with air.

In the present invention, anti-spark units are arranged between the micro-explosion unit 3 and the third-stage ejection unit 2, as well as in the pipeline of the energy release component, the purpose is to intercept the sparks generated in the gas after the micro-explosion, and prevent sparks from entering the third-stage Inside the injection unit 2.

In the present invention, the anti-spark unit and the micro-explosion chamber are connected by a pipeline, and the pipeline here can be made into a curved pipeline, one of which is to reduce the extension path of the micro-explosion reaction, prevent the reaction from spreading to the anti-spark unit, and improve safety; Second, reduce the conditions of the micro-explosion from the root. With the diffusion, the gas concentration of the micro-explosion decreases, which makes it impossible to meet the lower limit of the micro-explosion in the extension path, thereby preventing the long-distance diffusion of the reaction.

It should be noted that the micro-explosion chamber in the present invention is a closed reaction space. When the micro-explosion reaction starts for a period of time or when the micro-explosion chamber reaches the pressure limit, the micro-explosion reaction basically ends at this time, and the curved pipeline ensures The reaction of the gas produced by the micro-explosion gas is completely over when it reaches the anti-Mars unit.

The conditions to be met by the micro-explosion gas in the present invention are: non-toxic, relatively stable chemical properties, and short diffusion distance of the micro-explosion. In the present invention, the preferred micro-explosion gas is methane or ethane, and such gas is non-toxic in the case of complete micro-explosion and incomplete micro-explosion, and will not have toxic effects on wheat seeds.

The upper limit and lower limit of micro-explosion of methane are 15.4% (V/V) and 5.0% (V/V), and the upper limit of micro-explosion and lower limit of micro-explosion of ethane are 16.0% (V/V) and 3.0% % (V/V). Because the micro-explosion reaction of micro-explosion gas must meet the concentration within the micro-explosion limit range, in order to reduce the diffusion distance of micro-explosion, the concentration of micro-explosion gas in the micro-explosion reaction in the present invention only needs to reach above the micro-explosion. The limit, that is, it only needs to reach the micro-burst condition.

In the initial seed drying stage of the present invention, the water content of freshly harvested seeds is relatively large, and the moisture in the gas at the gas outlet end of the bin body 1 is relatively large during the drying process. The humidity regulating valve 6 closes the branch, and all the gas passes through the water vapor separator 5 After becoming dry gas, it is used to pass into the circulation port 26; when it is in the seed storage stage, in order to ensure the storage effect of the seeds to the greatest extent, it is necessary to ensure that the moisture of the seeds is in the range of 6% to 9%. 25 Continuously inject gas to form a circulating storage condition, which may lead to a decrease in the moisture content of the seeds. The humidity control valve compensates the ambient humidity of the warehouse 1 according to the moisture content of the seeds, thereby realizing the control of the moisture content of the seeds.
