Description

Technical Field

[0001] This application relates to the field of food extraction and processing equipment technology, and in particular to an extraction device for antioxidants in roasted nuts and seeds. Background Technology

[0002] Roasted nuts and seeds refer to snack foods made from plant fruits through methods such as sun-drying, baking, roasting, or frying, intended for consumption during leisure time. Common roasted nuts and seeds include sunflower seeds, broad beans, peanuts, walnuts, and chestnuts. To enhance the taste and color of roasted nuts and seeds, merchants often add appropriate amounts of additives during the roasting process, such as antioxidants, sweeteners, and coloring agents.

[0003] Antioxidants are a common additive in the roasting process of nuts and seeds. Antioxidants can effectively delay the oxidation of oils in roasted nuts and seeds, thereby extending their shelf life. They also inhibit the oxidation reaction of oxides in roasted nuts and seeds, maintaining their original taste and flavor. For example, roasted nuts and seeds rich in vitamin E can effectively maintain the oxidation of vitamin E under the action of antioxidants, thereby reducing the loss of nutrients during food storage.

[0004] Common oxidants used in roasted nuts and seeds include some antioxidants extracted from natural plants. The plants are slightly processed as raw materials, and solvents are added to the raw materials. After stirring, the raw materials and solvents are mixed together. Then, the mixture is heated to increase the reaction rate between the solvent and the raw materials. Next, the original solution after the reaction is coarsely filtered. Finally, through extraction and other processes, antioxidants can be extracted to form materials used to prepare antioxidants.

[0005] Typically, the mixing, heating, and coarse filtration of raw materials are carried out sequentially by several separate pieces of equipment. This requires transferring the raw materials from one piece of equipment to another, which not only reduces the efficiency of antioxidant preparation but also increases the cost of antioxidant preparation. Summary of the Invention

[0006] To simplify the preparation process of antioxidants needed for roasted nuts and seeds, this application provides an extraction device for antioxidants in roasted nuts and seeds.

[0007] This application provides an extraction device for antioxidants in roasted nuts and seeds, which adopts the following technical solution: An extraction device for antioxidants in roasted nuts and seeds includes a mixing tank and a heating layer. The heating layer covers the outer wall of the mixing tank. The bottom of the mixing tank is provided with a discharge port for discharging the antioxidant solution. The mixing tank is provided with a valve for controlling the opening and closing of the discharge port. A filter screen for preliminary filtration of raw material residue is provided inside the mixing tank. The filter screen is located above the discharge port and between the valve and the discharge port. A stirring impeller is rotatably installed inside the mixing tank. A driving device is provided on the mixing tank for driving the stirring impeller to rotate.

[0008] With the above technical solution, when the operator needs to prepare antioxidant stock solution using this equipment, the mixing tank is first heated, and then the raw materials (i.e., natural plants rich in antioxidants) are put into the mixing tank. Next, a solvent for dissolving antioxidants is injected into the mixing tank, so that the solvent and raw materials are mixed together. Then, the stirring impeller is driven by the drive device to rotate. Under the stirring action of the stirring impeller, the solvent and raw materials are fully mixed to improve the uniformity of the solution and raw materials. Finally, the operator opens the valve to allow the antioxidant stock solution to be filtered through the filter screen and flow out along the outlet, thereby obtaining the coarsely filtered antioxidant stock solution.

[0009] This equipment integrates the stirring impeller, heating layer, and filter plate into the mixing tank. Operators can complete the stirring, heating, and filtering of raw materials for antioxidant preparation using only this equipment. Compared with traditional separate production line equipment, it effectively improves the preparation efficiency of antioxidants and reduces the preparation cost of antioxidants.

[0010] In a preferred embodiment, the present application may be further configured such that: the driving device includes a motor and a rotating shaft, the motor is mounted on the mixing tank, the output shaft of the motor can drive the rotating shaft to rotate, and the stirring impeller is mounted on the rotating shaft.

[0011] With the above technical solution, after the operator puts the raw materials and solvent into the mixing tank, the operator starts the motor, and the output shaft of the motor starts to rotate. The output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring impeller to rotate. Under the stirring action of the stirring impeller, the mixing of raw materials and solvent can be accelerated, which can shorten the residence time of raw materials in the mixing tank, thereby improving the preparation efficiency of antioxidants.

[0012] In a preferred embodiment, this application can be further configured as follows: a limiting ring is provided inside the mixing tank, the bottom end of the rotating shaft is rotatably mounted on the limiting ring, a connecting rod is provided between the limiting ring and the inner wall of the mixing tank, one end of the connecting rod is fixedly connected to the inner wall of the mixing tank, and the other end of the connecting rod is fixedly connected to the limiting ring.

[0013] With the above technical solution, since the bottom end of the rotating shaft is rotatably mounted on the limiting ring, the stability of the rotating shaft is improved by the limiting ring's limiting effect on the rotating shaft during rotation.

[0014] In a preferred embodiment, this application can be further configured as follows: a first spur gear, a second spur gear, and a third spur gear are rotatably mounted on the mixing tank; a rotating shaft is mounted on the third spur gear; the first spur gear is mounted on the output shaft of the motor; the first spur gear and the second spur gear mesh with each other; and several drive shafts are mounted on both the first spur gear and the second spur gear. The drive shafts on the first spur gear are distributed circumferentially along the first spur gear, and the drive shafts on the second spur gear are distributed circumferentially along the second spur gear. The drive shafts on the first spur gear and the drive shafts on the second spur gear can respectively drive the third spur gear to rotate in the forward direction and in the reverse direction.

[0015] With the above technical solution, when the operator starts the motor, the output shaft of the motor drives the first spur gear to rotate, and the first spur gear drives the second spur gear to rotate synchronously.

[0016] When the drive shaft on the first spur gear and the teeth of the third spur gear come into contact, the drive shaft on the second spur gear and the teeth of the third spur gear are in a separated state. The drive shaft on the first spur gear can drive the third spur gear to rotate in the forward direction, which can also drive the stirring impeller to rotate in the forward direction.

[0017] When the drive shaft on the second spur gear and the teeth of the third spur gear come into contact, the drive shaft on the first spur gear and the teeth of the third spur gear are in a separated state. The drive shaft on the second spur gear can drive the third spur gear to rotate in the opposite direction, which can also drive the stirring impeller to rotate in the opposite direction.

[0018] Therefore, after the operator starts the motor, it can drive the stirring impeller to rotate in both the forward and reverse directions, thereby reducing the number of interlayers in the raw materials and further improving the uniformity of the raw materials and solvents, which in turn can increase the yield of antioxidant raw materials.

[0019] In a preferred embodiment, this application can be further configured such that: a baffle is slidably disposed inside the mixing tank along the vertical direction, and a driving mechanism is disposed on the mixing tank, the driving mechanism being used to drive the baffle to slide back and forth along the vertical direction.

[0020] With the above technical solution, after the operator puts the raw materials and solvents into the mixing tank, the operator starts the drive mechanism, which drives the baffle to slide back and forth in the vertical direction. This causes the baffle to cause the raw materials and solvents in the mixing tank to churn back and forth. Combined with the stirring of the impeller, the stirring dimension of the raw materials is increased, thereby further improving the uniformity of the raw materials and solvents.

[0021] In a preferred embodiment, the present application may be further configured such that the baffle is annular and the stirring impeller is rotatably disposed on the opposite inner side of the baffle.

[0022] With the above technical solution, since the baffle is circular and the impeller is located inside the baffle, on the one hand, the mutual interference between the baffle and the impeller is reduced, and on the other hand, the baffle can tumble the raw materials outside the range of the impeller's movement trajectory, thereby improving the mixing effect of the equipment on the raw materials and solvents.

[0023] In a preferred embodiment, the present application may be further configured such that: the driving mechanism includes a lead screw, a driving rod, and a guide rod; the lead screw is rotatably mounted on the mixing tank; the driving rod and the guide rod are both mounted on the spoiler; the guide rod is slidably disposed on the mixing tank; and the lead screw is threadedly connected to the driving rod.

[0024] With the above technical solution, the operator can rotate the lead screw, and the drive rod moves back and forth in the vertical direction under the driving action of the lead screw and the guiding action of the guide rod, which can drive the spoiler to move back and forth in the vertical direction.

[0025] In a preferred embodiment, this application can be further configured such that: a first synchronous pulley and a second synchronous pulley are rotatably disposed on the mixing tank, the first synchronous pulley is mounted on the lead screw, the second synchronous pulley is mounted on the output shaft of the motor, and a synchronous belt is sleeved on both the first synchronous pulley and the second synchronous pulley.

[0026] With the above technical solution, when the operator drives the motor, on the one hand, the output shaft of the motor can drive the stirring impeller to rotate, thereby stirring the raw materials; on the other hand, the output shaft of the motor can also drive the lead screw to rotate, thereby driving the baffle to move back and forth in the vertical direction, and churning the raw materials and solvents in the mixing tank.

[0027] In a preferred embodiment, this application can be further configured as follows: the mixing tank is provided with an installation groove, an installation plate one and an installation plate two are inserted into the installation groove, the filter screen is disposed between the installation plate one and the installation plate two, a connector is provided between the installation plate one and the installation plate two, and the installation plate one and the installation plate two are connected by the connector.

[0028] With the above technical solution, since the filter screen is clamped between mounting plate one and mounting plate two, the operator can pull out mounting plate one and mounting plate two from the mounting groove to disconnect the connector from mounting plate one and mounting plate two, and facilitate the replacement of the filter screen or the cleaning of residue on the filter screen.

[0029] Furthermore, after opening the valve but before removing the filter screen, the operator can collect the antioxidant concentrate at the outlet. After removing the filter screen, the operator can collect the antioxidant residue at the outlet.

[0030] In a preferred embodiment, the present application may be further configured such that the connector includes bolts, and the first mounting plate and the second mounting plate are connected by the bolts.

[0031] Through the above technical solution, the connection and disassembly of mounting plate one and mounting plate two are realized by bolts, so that operators can replace the filter screen.

[0032] In summary, this application includes the following beneficial technical effects: 1. This equipment integrates the stirring impeller, heating layer and filter plate into the mixing tank. Therefore, the stirring, heating and filtering of raw materials for antioxidant preparation can be completed by this equipment alone. Compared with traditional split production line equipment, it effectively improves the preparation efficiency of antioxidants and reduces the preparation cost of antioxidants. 2. After the operator starts the motor, it can drive the stirring impeller to rotate in both the forward and reverse directions, thereby reducing the number of interlayers in the raw materials and further improving the uniformity of the raw materials and solvents, which in turn can increase the yield of antioxidant raw materials. 3. After the operator opens the valve, the raw antioxidant solution can be collected before the filter screen is removed. After the filter screen is removed, the raw antioxidant residue can be collected. This allows the raw antioxidant solution, raw materials, and residue to be removed in stages, simplifying the equipment structure and operating procedures. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0040] This application discloses an extraction device for antioxidants in roasted nuts and seeds.

[0041] See attached document Figure 1 and attached Figure 2 As shown, an extraction device for antioxidants in roasted nuts includes a mixing tank 1, which is an inverted cylindrical shape. The outer wall of the mixing tank 1 is covered with a heating layer 101. When the heating layer 101 is energized, it can heat the mixture in the mixing tank 1 to accelerate the reaction rate.

[0042] See attached document Figure 1 and attached Figure 2 As shown, the top of the mixing tank 1 is closed, and an inlet 103 is provided on the mixing tank 1 to allow operators to add the antioxidant plant material and solvent into the mixing tank 1. The bottom of the mixing tank 1 is open, which is the outlet 102 of the mixing tank 1, so that the antioxidant concentrate and raw material residue can be discharged from the outlet 102. A flange is also provided at the bottom of the mixing tank 1 to facilitate connection with other equipment or pipelines.

[0043] See attached document Figure 1 and attached Figure 2 As shown, a valve 11 is installed at the bottom of the mixing tank 1, which controls the opening and closing of the discharge port 102. A filter screen 12 is installed inside the mixing tank 1, which is used for preliminary filtration of antioxidant raw material residues. The valve 11, filter screen 12, and discharge port 102 are distributed sequentially from top to bottom. Several stirring impellers 13 are rotatably installed inside the mixing tank 1 to fully mix the antioxidant raw materials and solvents. The stirring impellers 13 are evenly distributed vertically.

[0044] See attached document Figure 2 and attached Figure 3 As shown, a drive device 2 is provided on the mixing tank 1, which is used to drive the stirring impeller 13 to rotate. The drive device 2 includes a motor 21 and a rotating shaft 22. The motor 21 can drive the rotating shaft 22 to rotate. Several stirring impellers 13 are fixedly connected to the rotating shaft 22. The motor 21 is a double-headed motor 21. The motor 21 is installed on the top of the mixing tank 1. The rotating shaft 22 is installed on the mixing tank 1 and is set vertically. One end of the rotating shaft 22 extends into the mixing tank 1, and the other end extends out of the top of the mixing tank 1.

[0045] When the operator needs to prepare antioxidant stock solution using this equipment, the heating layer 101 is first preheated by powering on. Then, the raw materials (i.e., natural plants rich in antioxidants) and solvent (used to dissolve antioxidants) are put into the mixing tank 1. The motor 21 is then started. The motor 21 drives the stirring impeller 13 to rotate through the rotating shaft 22, so that the solvent and raw materials are fully mixed. Finally, the operator opens the valve 11, so that the antioxidant stock solution flows out through the filter screen 12 and then through the discharge port 102, thereby obtaining the coarsely filtered antioxidant stock solution.

[0046] This equipment can complete the stirring, heating, and filtration of raw materials for antioxidant preparation. Compared with traditional split-line equipment, it effectively improves the preparation efficiency of antioxidants and reduces the preparation cost.

[0047] See attached document Figure 2 As shown, a limiting ring 221 is installed inside the mixing tank 1. The limiting ring 221 is horizontally positioned, and the bottom end of the rotating shaft 22 is rotatably mounted on the limiting ring 221. Under the limiting effect of the limiting ring 221 on the rotating shaft 22, the stability of the rotating shaft 22 during rotation is improved. Several connecting rods 222 are provided between the limiting ring 221 and the inner wall of the mixing tank 1. The connecting rods 222 are used to fix the limiting ring 221. Each connecting rod 222 is horizontally positioned, and the several connecting rods 222 are evenly distributed along the circumference of the limiting ring 221. Both the connecting rods 222 and the limiting ring 221 are located below the stirring impeller 13. One end of the connecting rod 222 is fixedly connected to the inner wall of the mixing tank 1, and the other end is fixedly connected to the limiting ring 221.

[0048] See attached document Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, a first spur gear 31, a second spur gear 32, and a third spur gear 33 are rotatably mounted on the top of the mixing tank 1. The rotating shaft 22 is coaxially fixedly connected to the third spur gear 33, and the first spur gear 31 is coaxially fixedly connected to the output shaft of the motor 21. The first spur gear 31 and the second spur gear 32 mesh with each other, and the third spur gear 33 is located above the first spur gear 31 and the second spur gear 32.

[0049] See attached document Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, several drive shafts 301 are mounted on the top surface of both the first spur gear 31 and the second spur gear 32. The drive shafts 301 are all vertically arranged. The drive shafts 301 on the first spur gear 31 are evenly distributed along the circumference of the first spur gear 31, and the drive shafts 301 on the second spur gear 32 are evenly distributed along the circumference of the second spur gear 32. The drive shafts 301 on the first spur gear 31 and the drive shafts 301 on the second spur gear 32 can drive the third spur gear 33 to rotate in the forward and reverse directions, respectively. Each drive shaft 301 is rotatably mounted with a roller 302 to reduce friction.

[0050] When the teeth of the drive shaft 301 on the first spur gear 31 and the third spur gear 33 make contact, the teeth of the drive shaft 301 on the second spur gear 32 and the third spur gear 33 are in a separated state. The drive shaft 301 on the first spur gear 31 can drive the third spur gear 33 and the stirring impeller 13 to rotate in the forward direction. When the teeth of the drive shaft 301 on the second spur gear 32 and the third spur gear 33 make contact, the teeth of the drive shaft 301 on the first spur gear 31 and the third spur gear 33 are in a separated state. The drive shaft 301 on the second spur gear 32 can drive the third spur gear 33 and the stirring impeller 13 to rotate in the reverse direction.

[0051] In summary, after the operator starts the motor 21, the stirring impeller 13 can rotate intermittently in the forward and reverse directions to reduce the number of interlayers in the raw materials, thereby further improving the uniformity of the raw materials and solvents, and thus increasing the yield of antioxidant raw materials.

[0052] See attached document Figure 2 and attached Figure 3 As shown, a baffle 4 is vertically slidably installed inside the mixing tank 1. The baffle 4 can cause the raw materials and solvents in the mixing tank 1 to churn back and forth. Combined with the stirring of the impeller 13, it increases the stirring dimension of the raw materials, thereby further improving the uniformity of the raw materials and solvents. The baffle 4 is annular, and the axis of the baffle 4 is collinear with the axis of the mixing tank 1. The impeller 13 is rotatably installed on the inner side of the baffle 4. This not only reduces the mutual interference between the baffle 4 and the impeller 13, but also allows the raw materials outside the movement trajectory range of the impeller 13 to be churned, thereby improving the stirring effect of the equipment on the raw materials and solvents.

[0053] See attached document Figure 2 and attached Figure 3As shown, a drive rod 52 and a guide rod 53 are fixedly connected to the top surface of the spoiler 4. Both the drive rod 52 and the guide rod 53 are vertically arranged. The guide rod 53 is slidably arranged on the mixing tank 1. A lead screw 51 for driving the spoiler 4 to move back and forth is rotatably installed on the mixing tank 1. The bottom end of the lead screw 51 extends into the mixing tank 1 and is threaded to the drive rod 52. The top end of the lead screw 51 extends out of the mixing tank 1. A synchronous pulley 1 511 is coaxially fixedly connected to the top end of the lead screw 51. A synchronous pulley 211 is coaxially fixedly connected to the output shaft of the motor 21. Both synchronous pulley 1 511 and synchronous pulley 211 are located at the top of the mixing tank 1. A synchronous belt 212 is fitted on both synchronous pulley 1 511 and synchronous pulley 211.

[0054] When the operator starts the motor 21, the motor 21 can not only drive the stirring impeller 13 to rotate intermittently in the forward and reverse directions, but also drive the baffle 4 to move back and forth in the vertical direction through the synchronous pulley 1 511, synchronous pulley 211, synchronous belt 212 and lead screw 51 to increase the stirring dimension of the raw materials.

[0055] See attached document Figure 1 Appendix Figure 2 and appendix Figure 5 As shown, the mixing tank 1 is provided with an installation groove 14, which is located between the discharge port 102 and the valve 11. An installation plate 1 61 and an installation plate 2 62 are inserted into the installation groove 14. The filter screen 12 is located between the installation plate 1 61 and the installation plate 2 62. The installation plate 1 61 and the installation plate 2 62 are connected by bolts 631. A handle 611 is fixedly connected to the installation plate 1 61, which makes it easy for the operator to pull out the installation plate 1 61, the filter screen 12 and the installation plate 2 62 from the installation groove 14.

[0056] After the operator opens valve 11, before removing filter screen 12, the operator can collect the antioxidant concentrate at the discharge port 102. After removing filter screen 12, the operator can collect the antioxidant residue at the discharge port 102, thus enabling the antioxidant concentrate, raw materials, and residue to be removed in stages, simplifying the equipment structure and operating procedures.

[0057] The operator removes the filter screen 12 to clean any residue. The operator then loosens bolts 631 from the mounting plate 61 and mounting plate 62 to replace the filter screen 12.

[0058] The implementation principle of this embodiment is as follows: This equipment integrates the stirring impeller 13, the heating layer 101 and the filter plate on the mixing tank 1. Therefore, the operator can complete the stirring, heating and filtering of the raw materials for antioxidant preparation using only this equipment. Compared with the traditional split assembly line equipment, it effectively improves the preparation efficiency of antioxidants and reduces the preparation cost of antioxidants.

[0059] The embodiments described in this specific implementation are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
