Description

Technical Field

[0001] This utility model belongs to the field of cooling and preservation, specifically relating to a rice bran puffing and preservation device. Background Technology

[0002] Rice bran oil is a highly nutritious edible oil, rich in active substances such as oryzanol, phytosterols, and vitamin E (tocopherols and tocotrienols). A key step in rice bran oil production is stabilization and enzyme inactivation, a common method being extrusion puffing. Although the high-temperature treatment after puffing kills some microorganisms and enzymes, rice bran's high fat content (especially unsaturated fatty acids) and loose, hygroscopic structure make it more susceptible to oxidation, rancidity, and mold growth than unpuffed rice bran. Therefore, proper preservation of rice bran is crucial.

[0003] Patent application CN202310806587.4 discloses a method and device for preserving puffed rice bran, which includes a cooling box with a cooling mechanism inside. The cooling mechanism includes a push plate movably connected inside the cooling box. This mechanism cools the puffed rice bran, rapidly transferring internal heat away, and allows for the recycling of cooling water, thus saving resources. However, in this cooling mechanism, the annular tube, fixing rod, and actuating rod cannot fully contact the rice bran during cooling, affecting the cooling efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a rice bran puffing and preservation device.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A rice bran puffing and preservation device includes a frame with first cooling box devices on both sides. A feeding plate device is fixedly connected to the lower end of the frame, and an upper plate is fixedly connected to the upper end of the frame. A second cylinder device is provided on the upper plate. A vertically penetrating sealed box is fixedly connected between the feeding plate device and the upper plate. Air pump devices are provided on the left and right sides of the sealed box, and the two air pump devices are respectively connected to the first cooling box devices. The feeding plate device is slidably and sealingly connected to the sealed box. A second cooling box device is sealed and fixedly connected to the upper opening of the sealed box. A lifting cooling plate device is slidably and sealingly connected inside the second cooling box device. The lifting cooling plate device is fixedly connected to the second cylinder device and can slide downwards and sealably through the second cooling box device into the sealed box. The left and right sides of the second cooling box device are respectively connected to the first cooling box device.

[0007] As a further feature of the above scheme, a vertically penetrating cooling chamber is opened inside the sealed box, and the cooling chamber is connected to the air pump device. The first cooling box device is equipped with a spiral heat exchange tube, the lower end of which is connected to the air pump device, and the upper end of which is connected to the second cooling box device. Cooling water is circulated and added to the first cooling box device. When the air passes through the spiral heat exchange tube, it is cooled down, and the cold air can circulate between the first cooling box device, the sealed box, and the second cooling box device.

[0008] As a further feature of the above solution, the feeding plate device includes a base plate and a feeding plate. The base plate is fixedly connected to the lower end of the frame. A first cylinder device is provided on the base plate. The upper end of the first cylinder device is fixedly connected to the feeding plate. The feeding plate is slidably connected in a sealed manner in the cooling chamber. A spring column device is provided between the base plate and the feeding plate.

[0009] As a further provision of the above scheme, the second cooling box device includes a second cooling box, the upper end face of the second cooling box is fixedly connected to the upper plate, and the lower plate of the second cooling box has evenly distributed long sliding grooves running vertically through the left and right directions, and evenly distributed guide hole grooves are formed on the long sliding grooves.

[0010] As a further feature of the above scheme, a vertically upward feeding pipe is provided at the center of the lower plate of the second cooling box. The feeding pipe extends upward out of the upper plate, and a reset spring column device is connected to the lower end of the feeding pipe. A baffle plate is fixedly connected to the lower end of the reset spring column device, and a guide cone is provided on the upper surface of the baffle plate.

[0011] As a further provision of the above scheme, the output end of the second cylinder device is fixedly connected to a vertically arranged connecting rod. The connecting rod slides and seals downward into the second cooling box. The lifting cooling plate device includes a lifting plate, which is fixedly connected to the connecting rod and slidably and sealably connected to the inner wall of the second cooling box. The lifting plate is provided with a one-way valve, which opens upward and closes downward. The lifting plate is provided with evenly distributed vertically downward air columns, each with an upward through hole. The lower end of the air column has a front-to-back through air outlet. The air columns are correspondingly arranged with the guide slot and are slidably and sealably connected. A vertically arranged cooling plate is fixedly connected to the air column in the left-right direction, and the cooling plate is slidably and sealably connected to the long sliding groove.

[0012] This utility model has the following beneficial effects:

[0013] The feeding plate and the second cooling box form a sealed space within the cooling chamber. Rice bran is added to the cooling chamber through the feeding pipe. Two air pump devices are activated: one air pump draws air from the cooling chamber, while the other pump adds air. Working together, the hot air in the cooling chamber enters the first cooling box on one side. The hot air is cooled down by passing through the spiral heat exchange tube and then enters the second cooling box, where it cools the cooling plate. After being cooled by the first cooling box on the other side, the air re-enters the cooling chamber to circulate and cool the rice bran. The second cylinder device is activated, which drives the cooling plate through a long sliding groove and downwards into the cooling chamber to contact and cut the rice bran. While cooling the rice bran, the cooling plate can also form left and right lateral cutting grooves, increasing the contact area between the cold air and the rice bran and greatly improving the cooling efficiency.

[0014] When the lifting plate descends, the cold air in the second cooling box enters above the lifting plate through the one-way valve. When the lifting plate rises, the one-way valve closes downwards, and the cold air is compressed and can only be blown directly into the rice bran through the through hole and the air outlet, further improving the cooling efficiency.

[0025] like Figure 3 As shown, the second cooling box device 6 includes a second cooling box 601. The upper end face of the second cooling box 601 is fixedly connected to the upper plate 3. The lower plate of the second cooling box 601 has evenly distributed vertically penetrating horizontally elongated grooves 602. The elongated grooves 602 have evenly distributed guide holes 603. A vertically upward feeding pipe 604 is provided at the center of the lower plate of the second cooling box 601. The feeding pipe 604 extends upward out of the upper plate 3. The lower end of the feeding pipe 604 is connected to a reset spring column device 6041. The lower end of the reset spring column device 6041 is fixedly connected to a baffle plate 6042. A guide cone 6043 is provided on the upper end face of the baffle plate 6042. When rice bran is added, the baffle plate 6042 automatically opens when it is squeezed. After the rice bran is added, the baffle plate 6042 and the guide cone 6043 automatically seal the lower end of the feeding pipe 604 under the action of the reset spring column device 6041.

[0027] The working process of this utility model is as follows: Before cooling rice bran, the feeding plate 204 and the second cooling box 601 form a sealed space in the cooling chamber 401. Rice bran is added to the cooling chamber 401 through the feeding pipe 604. When adding rice bran, the baffle plate 6042 automatically opens when it is squeezed. After the rice bran is added, under the action of the reset spring column device 6041, the baffle plate 6042 and the guide cone 6043 automatically seal the lower end of the feeding pipe 604. The two air pump devices 402 are started. The air pump device 402 on one side draws air from the cooling chamber 401, and the air pump device 402 on the other side adds air to the cooling chamber 401. With their cooperation, the cooling chamber 401 cools down. Hot air from compartment 01 enters the first cooling box device 5 on one side. After being cooled by the spiral heat exchange tube 501, the hot air enters the second cooling box 601, where it cools the cooling plate 704. After being cooled by the first cooling box device 5 on the other side, the hot air re-enters the cooling chamber 401, where it circulates and cools the rice bran. The second cylinder device 301 is activated, and the connecting rod 302 drives the cooling plate 704 through the long sliding groove 602 and downward into the cooling chamber 401 to contact and cut the rice bran. While cooling the rice bran, the cooling plate 704 can form left and right slits, increasing the contact area between the cold air and the rice bran.

[0028] When the lifting plate 701 descends, the cold air in the second cooling box 601 enters above the lifting plate 701 through the one-way valve 702. When the lifting plate 701 rises, the one-way valve 702 closes downwards, and the cold air is compressed and can only be blown directly into the rice bran through the through hole 7031 and the air outlet 7032, further improving the cooling efficiency.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
