[0063] exist Figure 9 to Figure 10 In a preferred but non-limiting embodiment of the present invention, the granulation device further includes an intermittent grain conveying device, which includes an assembly table 26 connected between the arch 8 and the liquid holding basin 3, a through channel 1 27 fixedly connected to the assembly table 26, a through channel 2 28 pivotally assembled on the assembly table 26 and located below the outlet of the through channel 1 27, and a linkage part and a spring 29 pivotally assembled below the through channel 2 28 and away from the pivot position of the through channel 2 28 and the assembly table 26.

[0064] In a preferred but non-restrictive embodiment of the present invention, the linkage portion includes a connecting strip 32 and a bead-shaped member 33 fixedly connected to one end of the connecting strip 32, the other end of the connecting strip 32 is screwed to the through-type channel 2 28, the inner surface of the arched hole 31 is in close contact with the outer surface of the bead-shaped member 33, one end of the spring 29 is connected to the bottom of the through-type channel 2 28, and the other end of the spring 29 is connected to the bead-shaped member 33; in the free state, the through-type channel 2 28 is in a suspended state under the pull of weight, and there is a gap between the through-type channel 2 28 and the lower outlet of the through-type channel 1 27 for grains to shuttle, and the lower bead-shaped member 33 is located in the arched hole 31 here under the traction of the spring 29; the weight that the grains are subjected to at the opening 30 position is higher than the force of throwing them outward, so as to ensure that the grains are reliably delivered into the granulation container 6 at the filter eye 34 position on the opening 30.

[0065] When the grains arrive at the through-channel 1 27, the granulation container 6 pulls the opening 30 to rotate together during the rotation. During this period, the bead 33 and the arch hole 31 are constantly attached to and separated from each other. Under the guidance of the connecting strip 32 and the pull of the spring 29, the through-channel 2 28 swings vertically back and forth around the pivot position. The through-channel 2 28 and the outlet below the through-channel 1 27 are in a closed and open switching state, so that the grains are constantly distributed and fall onto the filter eye 34 at the position of the opening 30, preventing a large amount of grains from arriving at the granulation container 6 and interfering with the rotation of the granulation container 6, thereby reducing the frequency of the granulation container 6 being interrupted and stopped from rotating due to blockage; the filter eye 34 can filter the grains flowing through, allowing the dust to fall into the liquid holding basin 3 through the filter eye 34.

[0066] The granulation method of the granulation device of the present invention is: The grains are sent to the through-channel 1 27, and the grains in the through-channel 1 27 are passed through the through-channel 2 28 to the filter eye 34 of the opening 30, and the grains are filtered for dust through the filter eye 34; Cooling granulation treatment: When the grains arrive at the granulation container 6, the liquid level in the liquid holding basin 3 is higher than the top of the granulation block 7. The pump 4 pressurizes the refrigerant in the liquid holding basin 3 and sends it to the rotator and pulls the roller body 10 to rotate. The granulation container 6 rotates together, and the granulation block 7 is in a constant state. The grains are granulated between the granulation container 6 and the granulation block 7. The granulated grains fall along the roller body 10. During this period, the refrigerant in the circulation passage 5 in the cover body 9 continues to cool the granulated grains passing through the roller body 10. The temperature of the grains during granulation is maintained at room temperature, and the granulated grains are stored. Therefore, by performing room temperature granulation treatment on the grains, the loss of nutrients in the grains can be effectively reduced, providing better ingredients for the preparation of the carbohydrate matrix of the grains used for special medical foods in the future; at the same time, the defect of grains sticking together due to the scorching effect of granulation is avoided, and the waste of grains is reduced, ensuring the carbohydrate content of the grains used for special medical foods in the future. The quality of the matrix of the compound; the grains are sent to the granulation container, and the pumping machine is operated. The pumping machine pressurizes the refrigerant in the liquid holding basin and sends it to the cover body on the rotator. After the refrigerant rushes into the cover body, it acts on the rotating roller and pulls the rotating roller to rotate. The rotating roller pulls the roller body and the granulation container to rotate. The grains are granulated between the granulation container and the granulation block. During this period, the granulation container is completely in the refrigerant in the open water outlet trough. The heat energy at the position of the granulation container can be efficiently dissipated in the refrigerant, which reduces the temperature of the grain during granulation. The grains after granulation fall along the roller body. During this period, the refrigerant in the circulation path in the cover body continues to cool the grains after granulation, ensuring that the grains are in a refrigerated state during granulation. The grains can be cooled during granulation and the loss of nutrients in the grains can be reduced. The pumping machine is used to pressurize the refrigerant to achieve the rotary drive of the granulation container and achieve the reciprocating operation of the refrigerant, which is low in consumption.
