[0020] Among them, the composite treatment cylinder 7 includes a cylinder body 71, an annular groove 72 and a guide outlet 73. The cylinder body 71 is movably sleeved in the thermal insulation sleeve 5. The annular groove 72 is opened on the outer surface of the cylinder body 71.

[0023] The lifting control assembly 9 controls the up and down movement of the composite treatment cylinder 7, and through the cooperation of the sleeve shaft 92 and the sleeve cavity 15, ensures that the composite treatment cylinder 7 is controlled to move up and down while allowing the composite treatment cylinder 7 to deflect itself.

[0024] Among them, a feeding assembly 12 is fixedly provided on the top of the storage tank 1, and the outlet end of the feeding assembly 12 faces the adjustable support assembly 6. The feeding assembly 12 includes a feeding frame 121, a feeding pipe 122 and a sealing plug 123. The feeding pipe 122 is fixedly sleeved on the top of the storage tank 1, and the lower end is located above the adjustable support assembly 6. The upper end of the feeding pipe 122 is fixedly connected and communicated with the feeding frame 121, and the sealing plug 123 is movably sleeved on the upper end of the feeding pipe 122. An electric push rod 2 is provided inside the feeding frame 121, and the movable end of the electric push rod 2 is fixedly connected to the sealing plug 123.

[0025] The feeding component 12 realizes the feeding processing of wheat seeds. When the feeding tube 122 is opened, the wheat seeds are directional-loaded into the adjustable support component 6, and the sealing plug 123 is sleeved in the feeding tube 122 to prevent the wheat seeds from continuing to fall. The outside of the processing box 2 can be connected to an external ventilation structure, and the air volume is introduced into the processing box 2 when drying the wheat seeds. The small gap between the sealing plug 123 and the feeding tube 122 can realize the extraction of the air volume fed into the processing box 2.

[0026] First embodiment: When in use, the wheat seeds to be processed are put into the loading frame 121 of the loading assembly 12, the electric push rod 2 is started and drives the sealing plug 123 to move up to open the loading tube 122, and the wheat seeds fall into the various adjustable support components 6 through the loading tube 122 and fall on the top of the carrier plate 63, the heating tube 4 is started, the temperature in the processing box 2 increases, and the heat acts on the wheat scattered on the carrier plate 63, so that the moisture inside the wheat evaporates, the lifting control assembly 9 is started, and the electric push rod 1 93 drives the cross plate 91 and the sleeve shaft 92 to move downward, so that the installed composite processing cylinder 7 moves downward, the cylinder body 71 moves downward along the inside of the heat insulation sleeve 5, and drives the mounting ring 8 to move downward along the adapter 13, thereby driving the carrier plate 63 to rotate and swing downward through the sleeve rod 64, and drives the elastic rod 65 to stretch and deform, and as the cylinder body 71 moves downward a short distance, it moves up again to reset, so that the carrier plate 63 swings up and resets, reciprocating. The operation causes the top of the carrier plate 63 to vibrate and act on the wheat seeds on the top. The wheat seeds vibrate on the carrier plate 63 and cooperate with the heating tube 4 to complete the drying of the wheat seeds and reduce the moisture content. After drying for a certain period of time, the cylinder 71 is manually pushed, causing the cylinder 71 to deflect laterally around the inside of the insulation sleeve 5, so that the guide outlet 73 rotates to above the adapter 13. Then, the lifting control component 9 is started again, driving the cylinder 71 to move downward again, so that the guide outlet 73 moves downward to the adapter 13. At this time, the carrier plate 63 remains tilted and tilted downward. The dried wheat seeds on the top of the carrier plate 63 rotate and roll down, and fall into the inside of the cylinder 71. Then, they fall downward through the dispersion and micro-freezing component 10 into the storage tank 1, completing the drying and micro-freezing storage. Then, the composite processing cylinder 7 is raised and rotated laterally to reset. The loading component 12 is reopened, and the next group of wheat seeds to be micro-frozen and stored is put into the processing box 2 for the next group of processing.

[0027] First, through the cooperation of the adjustable support component 6, the composite processing cylinder 7 and the dispersion micro-freezing component 10, continuous processing of drying and micro-freezing storage is realized. The up and down movement of the composite processing cylinder 7 completes vibration dispersion, realizes uniform drying of the wheat seeds in the processing box 2, improves the drying effect, reduces the moisture content, avoids internal frostbite during micro-freezing, and automatically controls the carrier plate 63 in the adjustable support component 6 to tilt and automatically unload after deflection and downward movement, quickly realizes efficient unloading after dispersed drying, reduces intermediate feeding and discharging and transfer processing procedures, improves continuous processing efficiency, and realizes continuous drying and micro-freezing storage processing for batch wheat seeds, with automatic integrated processing and high comprehensive processing efficiency.

[0028] Among them, a cold air inlet pipe is provided on the side of the storage tank 1, and the cold air inlet pipe is connected to the cold air distribution component 3. The cold air distribution component 3 includes a connecting cavity 31, a sleeve 32 and an air guide pipe 33. The connecting cavity 31 is opened in the inner wall of the bottom of the storage tank 1 and is connected to the cold air inlet pipe.

The air guide pipe 33 is fixedly connected to the bottom of the inner cavity of the storage tank 1 and is connected to the connecting cavity 31.

[0029] The cold air input pipe can realize the cold air input of the external refrigeration and ventilation structure, realize the cold air input into the cold air distribution component 3, complete the cold air introduction of the storage tank 1 and the dispersed micro-freezing component 10, and realize the micro-freezing storage process.

[0030] Among them, the interior of the composite processing cylinder 7 is fixedly provided with a dispersion and micro-freezing component 10, which includes an intermediate rod 101, a bottom cavity 102, a spiral blade 103 and an air hole 104.

The bottom cavity 102 is opened at the bottom of the intermediate rod 101, and the air hole 104 is opened on the outer surface of the intermediate rod 101. The bottom of the intermediate rod 101 is movably sleeved in the sleeve 32.

[0031] By utilizing the spiral channel formed by the dispersion micro-freezing assembly 10 and the barrel 71, while guiding the dried wheat seeds to spirally fall, combined with the cold air input into the spiral channel, sufficient micro-freezing treatment is achieved to ensure micro-freezing uniformity.

[0032] Among them, a bypass mechanism is provided inside the composite treatment tube 7, the air inlet end of the bypass mechanism is communicated with the interior of the composite treatment tube 7, and the bypass mechanism includes a cold air output pipe.

One end of the bypass port 16 is connected to the sleeve cavity 15. The connecting cover 11 is fixedly connected to the top of the storage tank 1 and is sleeved on the outside of the cylinder 71. The internal annular cavity of the connecting cover 11 is connected to the other end of the bypass port 16, and the outer side surface of the connecting cover 11 is connected to the cold air output pipe.

[0035] The bypass mechanism guides the cold air in the dispersed micro-freezing assembly 10 to the outside along the cylinder 71 and circulates it into the refrigeration and ventilation mechanism to complete the circulating cold air treatment. The connecting cover 11 ensures that normal cold air can be guided out when the cylinder 71 rotates.

[0036] Second embodiment: During pre-drying of wheat seeds before micro-freezing, an external refrigeration device is activated and cool air is introduced into the cool air distribution assembly 3 through the cool air inlet pipe. The cool air is then introduced into the connecting cavity 31 and distributed to the sleeve 32 and the air guide pipe 33. The cool air entering the air guide pipe 33 is further introduced into the storage tank 1 through the side holes, causing the internal temperature of the storage tank 1 to decrease. The cool air in the sleeve 32 is directed upward into the bottom cavity 102 of the intermediate rod 101 in the micro-freezing dispersion assembly 10 and is then introduced into the spiral blade 103 along the air hole 104. The wheat seeds that fall into the barrel 71 then spiral downward along the spiral blade 103, coming into contact with the cool air flowing out from various locations. The micro-freezing process is completed during the spiral sliding. The cool air is then directed upward through the connecting port 14, the bypass port 16, and the connecting cover 11 of the bypass mechanism and flows back into the external refrigeration outlet mechanism through the external cool air outlet pipe.

[0037] First, after drying is completed, the wheat seeds are fully dried through the cylinder 71 and the dispersion micro-freezing component 10, and the cold air input into the dispersion micro-freezing component 10 and the wheat seeds sliding downward along the spiral blades 103 are combined with the above-mentioned drying treatment structure. After the wheat seeds are fully dried, they are introduced into the spiral channel surrounded by the spiral blades 103 and the cylinder 71 in small quantities and multiple times. The cold air introduced into the channel makes the surface of the wheat seeds fully contact with the cold air, thereby improving the effect of the micro-freezing treatment of the wheat seeds after drying. By extending the micro-freezing time and increasing the micro-freezing path, efficient and uniform micro-freezing treatment is completed.

[0038] Among them, the bypass mechanism is the guide port 17, which is opened on the outer surface of the cylinder 71 and is located below the annular groove 72. The guide port 17 corresponds one-to-one with the adapter port 13, and the adapter port 13 is located on the rotation path of the guide port 17. The outer side surface of the storage tank 1 is fixedly connected to the cold air output pipe.

[0039] The bypass mechanism introduces cold air into the processing box 2, and the processing box 2 is used to guide the cold air to the external refrigeration and ventilation mechanism and enter the circulation. By introducing the cold air into the processing box 2, the wheat seeds in the processing box 2 are slightly frozen and cooled.

[0040] Third embodiment: When processing seeds that have been fully dried, the dried seeds are put into the adjustable support assembly 6 through the feeding assembly 12, and at the same time, the external refrigeration air outlet mechanism is maintained to input the cold air into the cold air distribution assembly 3, and part of the cold air is input into the cylinder 71 through the dispersion micro-freezing assembly 10, and is input into the inclined cavity 62 of the adjustable support assembly 6 along the guide port 17 and the adapter port 13, and acts on the wheat seeds upward along the small holes on the carrier plate 63, and at the same time fills the processing box 2, and the continuously filled cold air passes through the processing box The output pipe arranged on the outside is circulated and inputted into the external refrigeration air outlet mechanism, while the composite treatment cylinder 7 is kept moving up and down. The wheat seeds on the carrier plate 63 are vibrated and dispersed by the downward movement and reset of the carrier plate 63, so that the wheat seeds are fully slightly frozen and cooled. After the wheat seeds are evenly slightly frozen, the composite treatment cylinder 7 is pushed to deflect laterally and the composite treatment cylinder 7 is controlled to move downward. The carrier plate 63 tilts and downward to guide the slightly frozen wheat seeds into the cylinder body 71, and then completes secondary slight freezing along the dispersion slight freezing assembly 10, completing storage after sufficient slight freezing treatment.

[0041] First, by placing the wheat seeds into the adjustable support assembly 6 of the processing box 2, cooperating with the opening of the diversion port 17 and the movement control of the composite processing cylinder 7, the wheat seeds are dispersed and vibrated in the adjustable support assembly 6 after feeding, and the cold air diverted into the processing box 2 is micro-frozen. When the composite processing cylinder 7 is actuated and automatically realizes the export of the wheat seeds in the adjustable support assembly 6, and cooperates with the dispersion micro-freezing assembly 10 in the composite processing cylinder 7, double micro-freezing treatment is achieved. For wheat seeds with low water content, the cold air micro-freezing treatment under the two dispersion treatments can be completed to ensure that the wheat seeds have sufficient low-temperature micro-freezing preservation and storage effect.

[0042] The working principle and use process of the present invention are as follows: when in use, the wheat seeds to be processed are put into the feeding frame 121 of the feeding assembly 12, the electric push rod 2 is started and drives the sealing plug 123 to move upward to open the feeding tube 122, and the wheat seeds fall into the various adjustable support assemblies 6 through the feeding tube 122 and fall on the top of the carrier 63, the heating tube 4 is started, the temperature in the processing box 2 rises, and the heat acts on the wheat spread on the carrier 63, so that the moisture inside the wheat evaporates, the lifting control assembly 9 is started, and the electric push rod 1 93 drives the horizontal plate 9 1 and the sleeve shaft 92 move downward, causing the installed composite processing cylinder 7 to move downward, the cylinder body 71 moves downward along the inside of the heat insulation sleeve 5, and drives the installation ring 8 to move downward along the adapter 13, thereby driving the carrier plate 63 to rotate and swing downward through the sleeve rod 64, and driving the elastic rod 65 to stretch and deform. As the cylinder body 71 moves downward a short distance and then moves upward to reset, the carrier plate 63 swings upward to reset. The reciprocating action causes the top of the carrier plate 63 to vibrate and act on the wheat seeds on the top. The wheat seeds vibrate on the carrier plate 63 and cooperate with The heating tube 4 completes the drying of the wheat seeds and reduces the moisture content. After drying for a certain period of time, the cylinder 71 is manually pushed to make the cylinder 71 deflect laterally around the inside of the heat-insulating sleeve 5, so that the guide port 73 rotates to the top of the adapter 13. Then, the lifting control component 9 is started again to drive the cylinder 71 downward again, so that the guide port 73 moves downward to the adapter 13. At this time, the carrier plate 63 keeps tilting downward, and the dried wheat seeds on the top of the carrier plate 63 rotate and roll down, and fall into the inside of the cylinder 71, and then fall downward through the dispersion micro-freezing component 10. To the storage tank 1, complete the storage after drying and slight freezing; then raise the composite processing cylinder 7 and rotate the composite processing cylinder 7 horizontally to reset, reopen the loading assembly 12, and put the next group of wheat seeds to be slightly frozen and stored into the processing box 2 for the next group of processing; and the wheat seeds that fall into the cylinder 71 slide downward along the spiral blade 103 and come into contact with the cold air flowing out from various places during the falling process, and complete the slight freezing treatment during the spiral sliding period, and the cold air is discharged through the bypass mechanism and flows back to the external refrigeration outlet mechanism through the external cold air output pipe.
