Description

Technical Field

[0001] The present invention relates to a fresh-keeping device, in particular to a fresh-keeping device for soy product production. Background Art

[0002] Soy products are foods processed mainly from beans such as soybeans, adzuki beans, green beans, peas, broad beans, etc. Soy products are mainly divided into two categories: soy foods with soybeans as the main raw material and other soy products with other miscellaneous beans as the main raw material.

[0003] In order to extend the shelf life of soy products, dehydration and fresh-keeping treatment after soy product production is essential. Most of the existing soy product dehydration and fresh-keeping devices put soy products onto the filter screen for filtration and dehydration all at once during the dehydration process of soy products. However, this method has a low dehydration quality for a large amount of piled-up soy products, affecting the fresh-keeping quality. Moreover, too much oxygen content in the fresh-keeping device will promote the growth of microorganisms, thus easily causing spoilage of soy products and being unfavorable for the storage and fresh-keeping of soy products.

During the opening process of the timing valve, part of the soy products fall into the centrifugal box through the conveying sleeve. The centrifugal motor drives the centrifugal box at one end of the centrifugal rod to rotate. Under the action of centrifugal force, the water attached to the soy products in the centrifugal box is thrown out. The thrown-out water will flow into the water collecting tank intensively. The self-priming pump absorbs and transports the water in the treatment chamber to the collection box in time through the water suction pipe.

The rotation of the treatment block drives the centrifugal box in the treatment chamber to rotate. When the feeding port communicates with the bottom of the conveying sleeve during the rotation of the treatment block, the soy products in the centrifugal box will fall into the bottom fresh-keeping box through the feeding port. The second power shaft drives the conveying rod to rotate through the conveying mechanism. The rotation of the conveying pipe drives the auxiliary rod to rotate. The rotation of the auxiliary rod drives the stirring blades to rotate, so that the stirring blades stir the soy products evenly to avoid raw material accumulation. And the air pump transports the inert gas in the gas storage tank to the fresh-keeping box through the air delivery pipe. Under the action of the one-way pressure relief valve, part of the gas will be discharged, so as to reduce the oxygen content in the fresh-keeping box and increase the content of inert gas, delay the oxidation process of soy products, inhibit the growth of microorganisms, and thus extend the shelf life of food. As the sector gear continues to mesh, the treatment block continues to rotate. When the sector gear disengages from the power tooth groove, at this time the treatment block just rotates one week and resets. At this time, the timing valve will open again, and the soy products will continue to fall into the centrifugal box for dehydration treatment. In this way, the pre-dehydration treatment of the soy products to be stored can be realized, the water content in the soy products can be reduced, so as to slow down the growth and reproduction speed of microorganisms, extend the shelf life of soy products, and improve the fresh-keeping quality of soy products.

The air delivery assembly includes a hollow cavity. The auxiliary rod 25 is provided with a hollow cavity. A conveying pipe 27 is installed on the side wall of the hollow cavity. An installation hole is opened on the conveying pipe 27, and a one-way valve 28 is installed on the installation hole. The conveying pipe 27 communicates with the hollow cavity. A gas delivery pipe 37 is rotatably connected to the top of the hollow cavity. One end of the gas delivery pipe 37 away from the hollow cavity penetrates through the fresh-keeping box 2 and is connected to a gas storage tank 13. An air pump 15 is installed on the gas delivery pipe 37.;

[0021] In this embodiment, when preserving the soy products to be stored, first place them in the feeding box 4. The timing valve 17 arranged in the conveying sleeve 18 is opened intermittently at regular intervals. During the opening process of the timing valve 17, part of the soy products fall into the centrifugal box 33 through the conveying sleeve 18. The centrifugal motor drives the centrifugal box 33 at one end of the centrifugal rod 35 to rotate. Under the action of centrifugal force, the water attached to the soy products in the centrifugal box 33 will be thrown out, and the thrown water will fall to the bottom of the treatment chamber. The self-priming pump arranged absorbs the water in the treatment chamber in time through the water suction pipe 16 and conveys it to the collection box 5. During this period, the double-end motor (not shown in the figure and arranged in the power box 6) drives the first power shaft 9 and the second power shaft 7 to rotate. The rotation of the first power shaft 9 drives the power gear 10 to rotate. The rotation of the power gear 10 drives the annular sleeve 12 to rotate through meshing with the meshing groove 11. The rotation of the annular sleeve 12 drives the connected dial plate 22 to rotate. When the dial plate 22 rotates and contacts the dial rod 23, it will drive the sector gear 20 to rotate, so that the sector gear 20 meshes with the power tooth groove 21. During this meshing process, the sector gear 20 will drive the power rod 19 to rotate, and the rotation of the power rod 19 will further drive the connected treatment block 32 to rotate. The rotation of the treatment block 32 drives the centrifugal box 33 in the treatment chamber to rotate. When the feeding port communicates with the bottom of the conveying sleeve 18 during the rotation of the treatment block 32, the soy products in the centrifugal box 33 will fall into the bottom preservation box 2 through the feeding port. The second power shaft 7 drives the conveying rod 29 to rotate through the conveying mechanism 30. The rotation of the conveying pipe 27 drives the auxiliary rod 25 to rotate. The rotation of the auxiliary rod 25 drives the stirring blade 26 to rotate, so that the stirring blade 26 stirs the soy products evenly to avoid raw material accumulation. And the air pump 15 conveys the inert gas in the gas storage tank 13 to the preservation box 2 through the air delivery pipe 37. Under the action of the one-way pressure relief valve 14, part of the gas will be discharged, so as to reduce the oxygen content in the preservation box 2 and increase the content of inert gas, delay the oxidation process of soy products, inhibit the growth of microorganisms, and thus extend the shelf life of food. As the sector gear 20 continues to mesh, the treatment block 32 continues to rotate. When the sector gear 20 disengages from the power tooth groove 21, at this time the treatment block 32 just rotates one week and resets. At this time, the timing valve 17 will open again, and the soy products will continue to fall into the centrifugal box 33 for dehydration treatment. In this way, pre-dehydration treatment of the soy products to be stored can be realized, the water content in the soy products can be reduced, so as to slow down the growth and reproduction speed of microorganisms, extend the shelf life of soy products, and improve the preservation quality of soy products.

[0022] Further, the conveying mechanism 30 can be a gear set or a pulley set, etc., and no specific description is made here.

[0023] Further, the working principle of the timing valve 17 is mainly based on the synergistic effect of the timing device and the valve structure. The timing device is usually composed of components such as a timer, a solenoid valve, and a power supply, and they are electrically connected to each other, capable of precisely controlling the opening and closing time of the valve. Different time intervals can be set according to actual needs, and specific descriptions are not provided here.

[0024] Further, the inert gas can be nitrogen, carbon dioxide, or a mixed gas of nitrogen and carbon dioxide, and specific descriptions are not provided here.

[0025] Further, the bottom of the feeding box 4 is made of a transparent material to facilitate better observation of the amount of soy products in the feeding box 4.

[0026] Please refer to Figure 9 , as an embodiment of the present invention, the air delivery pipe 37 is installed at one end of the auxiliary rod 25 close to the conveying rod 29, and the air delivery pipe 37 is arranged below the stirring blade 26.

[0027] In this embodiment, the air delivery pipe 37 is installed at the bottom of the auxiliary rod 25. The air delivery pipe 37 is closer to the bottom of the fresh-keeping box 2. Then, during the process of introducing gas into the fresh-keeping box 2, as the introduced inert gas continuously increases, the gas at the bottom will flow upward, and the internal air pressure will continuously increase. Under the action of the one-way pressure relief valve 14, some of the internal oxygen can be discharged, thereby reducing the oxygen content in the fresh-keeping box 2, increasing the content of the inert gas, delaying the oxidation process of the soy products, and thus improving the fresh-keeping quality.

[0028] Please refer to Figures 4 to 5 , as an embodiment of the present invention, a water collecting trough 36 is opened on the bottom wall of the processing chamber, and the water suction pipe 16 is communicated with the water collecting trough 36.

[0029] In this embodiment, a water collecting trough 36 is opened on the bottom wall of the processing chamber. Then, when the centrifugal motor drives the centrifugal box 33 to rotate to perform centrifugal dehydration on the soy products placed in the centrifugal box 33, the water can flow more concentratedly into the water collecting trough 36, and then it is convenient for the water suction pipe 16 to more quickly drain the water in the processing chamber, reduce the moisture of the soy products poured from the centrifugal box 33 into the fresh-keeping box 2, and improve the fresh-keeping quality of the soy products.

[0030] The working principle of the present invention is as follows: When preserving soy products to be stored, first place them in the feeding box 4. The timing valve 17 provided in the conveying sleeve 18 is opened intermittently at a fixed time. During the opening process of the timing valve 17, part of the soy products fall into the centrifugal box 33 through the conveying sleeve 18. The centrifugal motor drives the centrifugal box 33 at one end of the centrifugal rod 35 to rotate. Under the action of centrifugal force, the water attached to the soy products in the centrifugal box 33 is thrown out. The thrown-out water will flow into the water collecting tank 36 centrally. The self-priming pump provided absorbs the water in the water collecting tank 36 through the water suction pipe 16 in time and conveys it to the collecting box 5. During this time period, the double-end motor drives the first power shaft 9 and the second power shaft 7 to rotate. The rotation of the first power shaft 9 drives the power gear 10 to rotate. The rotation of the power gear 10 drives the annular sleeve 12 to rotate through meshing with the meshing groove 11. The rotation of the annular sleeve 12 drives the connected toggle plate 22 to rotate. When the toggle plate 22 rotates and contacts the toggle rod 23, it will drive the sector gear 20 to rotate, so that the sector gear 20 meshes with the power tooth groove 21. During this meshing process, the sector gear 20 drives the power rod 19 to rotate. The rotation of the power rod 19 drives the connected processing block 32 to rotate. The rotation of the processing block 32 drives the centrifugal box 33 in the processing cavity to rotate. When the feed port communicates with the bottom of the conveying sleeve 18 during the rotation of the processing block 32, the soy products in the centrifugal box 33 will fall into the bottom fresh-keeping box 2 through the feed port. The second power shaft 7 drives the conveying rod 29 to rotate through the conveying mechanism 30. The rotation of the conveying pipe 27 drives the auxiliary rod 25 to rotate. The rotation of the auxiliary rod 25 drives the stirring blade 26 to rotate, so that the stirring blade 26 stirs the soy products evenly to avoid raw material accumulation. And the air pump 15 conveys the inert gas in the gas storage tank 13 to the fresh-keeping box 2 through the air delivery pipe 37. Under the action of the one-way pressure relief valve 14, part of the gas is discharged, so as to reduce the oxygen content in the fresh-keeping box 2, increase the content of inert gas, delay the oxidation process of soy products, inhibit the growth of microorganisms, and thus extend the shelf life of food. As the sector gear 20 continues to mesh, the processing block 32 continues to rotate. When the sector gear 20 disengages from the power tooth groove 21, at this time the processing block 32 just rotates one week and resets. At this time, the timing valve 17 will open again, and the soy products will continue to fall into the centrifugal box 33 for dehydration treatment. In this way, pre-dehydration treatment of the soy products to be stored can be realized, the water content in the soy products is reduced, so as to slow down the growth and reproduction speed of microorganisms, extend the shelf life of soy products, and improve the fresh-keeping quality of soy products.
