Description

Technical Field

[0001] This invention relates to the field of nut braising technology, and in particular to a braising equipment for nut braising and its usage method. Background Technology

[0002] In the process of nut braising, the uniformity of the braising liquid, temperature control, and recycling are key factors affecting the quality of the nut braising liquid.

[0003] In current nut braising methods, nuts are typically suspended inside the braising pot. However, when the nuts enter the pot, the temperature of the braising liquid rises due to the high temperature of the nuts from the previous steaming process. This causes the spice components in the braising liquid to evaporate more quickly, resulting in the loss of some volatile flavor compounds. At the same time, the high temperature environment also accelerates the denaturation of proteins and the oxidation of oils in the braising liquid, thus reducing the quality of the braising liquid and affecting the braising effect of subsequent batches of nuts.

[0004] Meanwhile, during the braising process, some debris and impurities will remain in the braising liquid, which needs to be filtered. However, if the braising liquid temperature is too high, direct filtration can easily damage the filter media, resulting in poor filtration effect and increased filtration cost.

[0005] Therefore, a brine braising device for nuts and spices and its usage method are proposed to solve the above problems. Summary of the Invention

The brine pot has multiple annular tubes fixed inside, and the outer sides of the multiple annular tubes are connected to horizontal tubes extending to the outside of the brine pot. The ends of the multiple horizontal tubes away from the annular tubes are connected to the diversion tubes. The annular tube is equipped with multiple unidirectional nozzles.

[0009] Preferably, it includes a closed tube connected to the inside of the annular tube, and a plug is slidably connected inside the closed tube. The end of the plug near the annular tube is hemispherical, and a spring is fixed at the end of the plug away from the annular tube. The other end of the spring is connected to the inside of the closed tube. A plugging ring is fixed inside the closed tube, and the side of the plugging ring away from the annular tube is matched with the end of the plug that is close to the annular tube. The outer side of the sealed tube is connected to multiple air jets arranged in a circular array. The end of the multiple air jets near the sealed tube corresponds to the plug, while the end of the multiple air jets away from the sealed tube is inclined towards the inside of the brine pot.

[0010] Preferably, it includes multiple L-shaped plates that are detachably bolted to the bottom wall of the cooling tank. The multiple L-shaped plates are arranged in a circular array. A spiral cooling pipe is fixed between the inner sides of the multiple L-shaped plates. The inlet of the spiral cooling pipe is connected to the end of the first connecting pipe away from the brine pot, and the outlet of the spiral cooling pipe is connected to the end of the second connecting pipe away from the filter box. The cooling structure also includes a water inlet pipe connected to the top of the outside of the cooling tank, and a water outlet pipe connected to the bottom of the outside of the cooling tank.

[0011] Preferably, the filter includes multiple filter plates disposed inside the filter box, the filter holes of the multiple filter plates decreasing in size from top to bottom, a support assembly disposed on the outer side of the filter plates, a cover plate detachably connected to the front of the filter box by bolts, a rubber sealing gasket disposed on the back of the cover plate and the front of the filter box, and a handle fixedly disposed on the front of the cover plate.

[0012] Preferably, the filter plate includes fixing blocks fixed to the left and right side walls of the inner cavity of the filter box, and a support groove is provided on the opposite side of each of the two fixing blocks. The front of the support groove is connected to the outside. Support blocks that are slidably connected to the inside of the support groove are fixed on both sides of the filter plate.

[0013] Preferably, the pump body is fixed to the top of the storage tank, the inlet of the pump body is connected to a water pumping pipe, the end of the water pumping pipe away from the pump body is connected to the bottom of the outer side of the storage tank, and the outlet of the pump body is connected to a return pipe, the end of the return pipe away from the pump body is connected to the top of the outer side of the brine pot.

[0014] Preferably, the bottom horizontal positions of the filter box and the cooling tank are both higher than the bottom horizontal position of the storage box, and a valve is provided on the first connecting pipe.

[0015] Preferably, the inner top of the brine pot is detachably connected to a mounting ring by bolts, and a protective net is fixed inside the mounting ring. The annular pipe and the one-way nozzle are located outside the protective net.

[0016] Another technical solution proposed by this invention is: a method for using a braising equipment for nut braising liquid, comprising the following steps: S1. After steaming and boiling, put the nuts that are to be braised into the brine pot through a cloth bag or fine metal mesh, ensuring that the nuts are completely submerged in the brine; S2. Start the blower. The airflow generated by the blower enters the annular tube through the diverter and horizontal tube. The airflow pressure pushes the plug to move away from the annular tube, compressing the spring. The plug separates from the plug ring, and the airflow enters the closed tube and is sprayed into the inside of the brine pot through multiple jet pipes, forming an annular airflow. This blows the brine to create bubbles, lowers the temperature of the brine, and at the same time, stirs the brine in all directions, so that the brine ingredients and brine are fully mixed. S3. When the braising process begins, open the valve on the first connecting pipe. The braising liquid that heats up during the braising process enters the spiral cooling pipe through the first connecting pipe. The cooling water in the cooling tank exchanges heat with the high-temperature braising liquid in the spiral cooling pipe, causing the braising liquid temperature to drop rapidly. The cooled braising liquid flows into the filter box through the second connecting pipe. S4. During the cooling process, open the valves of the inlet and outlet water pipes to circulate and replace the cooling medium, avoid excessively high cooling medium temperature, and ensure cooling effect; S5. The cooled brine will enter the filter box through the second connecting pipe. The cooled brine will be filtered through multiple filter plates in the filter box. The top filter plate removes large particles of impurities in the brine, such as brine residue. The middle filter plate removes medium-sized particles of impurities. The bottom filter plate removes fine impurities and suspended matter. The qualified brine after filtration flows into the storage tank through the third connecting pipe for storage. S6. While opening the valve of the first connecting pipe, start the pump body. The pump body draws the filtered brine from the storage tank through the water pumping pipe, and then transports the brine to the brine pot through the return pipe to realize the recycling of brine.

[0017] This invention provides a braising device for nuts and spices and its usage method, with the following beneficial effects: 1. This invention, by setting up a blowing structure, utilizes the airflow generated by a blower to spray annular airflow into the brine through a ring pipe and a one-way nozzle, thereby achieving the blowing of airflow into the brine. This allows the brine to fully contact the air, reducing the temperature of the brine. At the same time, the airflow can also stir the brine in all directions, preventing the brine ingredients from settling and ensuring that the nuts are evenly flavored. In addition, the sealed structure of the one-way nozzle can prevent brine backflow and nozzle blockage, extending the service life of the equipment.

[0018] 2. The cooling structure of this invention uses a combination of spiral cooling pipes and cooling tanks, which increases the contact area between high-temperature brine and cooling medium, enabling rapid cooling of the brine, avoiding direct filtration damage to the filter media, and improving the filtration effect.

[0019] 3. The filter structure of this invention adopts a multi-stage filter plate design, with the filter holes decreasing in size from top to bottom, which can gradually remove impurities of different particle sizes in the brine, resulting in good filtration effect. At the same time, the filter plate can be quickly installed and disassembled through the support components, which is convenient for cleaning and maintenance. Attached Figure Description

[0022] Example 1: like Figure 1-12 As shown, a nut braising equipment includes a base plate 1, a braising pot 2 fixed on the top of the base plate 1, braising liquid inside the braising pot 2, and a feeding pipe connected to the bottom of the braising pot 2 for easy replacement of the braising liquid. When braising nuts, the nuts are suspended through a cloth bag or a fine mesh bag and placed inside the braising pot 2 for braising.

[0023] The brine pot 2 is equipped with a blower structure 3 inside, which is used to blow air and stir the brine, so as to cool the brine and mix the brine ingredients thoroughly.

[0024] A cooling tank 4 is fixed to the top of the base plate 1 via a second mounting plate. The cooling tank 4 is equipped with a cooling structure 5, which is used to quickly cool the brine that has heated up during the braising process.

[0025] A filter box 6 is fixed to the top of the base plate 1 via a first mounting plate. The filter box 6 is equipped with a filter structure 7, which is used to perform multi-stage filtration on the cooled brine to remove impurities.

[0026] A storage box 8 is fixed on the top of the base plate 1 for storing filtered brine. A reflux structure 9 is provided above the storage box 8 to return the brine in the storage box 8 to the brine pot 2 for recycling.

[0027] The bottom outer side of the brine pot 2 is connected to a first connecting pipe 21 that is connected to the cooling structure 5, which is used to transport the brine heated during braising to the cooling structure 5. The top of the filter box 6 is connected to a second connecting pipe 61 that is connected to the cooling structure 5, which is used to transport the cooled brine to the filter structure 7. The bottom outer side of the storage box 8 is connected to a third connecting pipe 81 that is connected to the bottom outer side of the filter box 6, which is used to transport the filtered brine to the storage box 8 for storage.

[0028] like Figure 1-12 As shown, in the preferred embodiment, the blower 31 in the blower structure 3 is fixed to the top of the base plate 1, and the air outlet of the blower 31 is connected to the diversion pipe 32 for diverting the airflow generated by the blower 31.

[0029] The interior of the brine pot 2 is fixed with multiple annular tubes 33 by a support. The multiple annular tubes 33 are arranged in an array along the height direction of the brine pot 2. The outer side of each of the multiple annular tubes 33 is connected to a horizontal tube 34 extending to the outside of the brine pot 2. The end of the multiple horizontal tubes 34 away from the annular tubes 33 is connected to a diversion tube 32, so that the airflow in the diversion tube 32 is delivered to each annular tube 33 through the horizontal tube 34. A sealing gasket is provided at the connection between the horizontal tube 34 and the brine pot 2 to prevent brine leakage.

[0030] The annular tube 33 is equipped with multiple unidirectional nozzles 35 arranged in a circular array with uniform spacing. The unidirectional nozzles 35 are used to evenly spray the airflow inside the annular tube 33 into the brine, creating a foam in the brine and allowing it to fully contact the air, thus lowering the temperature of the brine. While cooling the brine, the nozzles also create a stirring effect, preventing sedimentation and ensuring that the ingredients and brine are fully integrated, thereby improving the efficiency of nut braising.

[0031] like Figure 1-12 As shown, in the preferred embodiment, the one-way nozzle 35 includes a closed tube 351 connected to the inside of the annular tube 33. A plug 352 is slidably connected inside the closed tube 351. The end of the plug 352 near the annular tube 33 is hemispherical, and a spring 353 is fixedly provided at the end of the plug 352 away from the annular tube 33. The other end of the spring 353 is connected to the inside of the closed tube 351.

[0032] A plugging ring 354 is fixed inside the closed tube 351. The side of the plugging ring 354 away from the annular tube 33 is adapted to the end of the plug 352 near the annular tube 33. The inner side of the plugging ring 354 is chamfered to facilitate the plug 352 and the plugging ring 354 to fit and seal, thereby achieving the sealing of the closed tube 351.

[0033] The outer side of the closed tube 351 is connected to multiple air jet pipes 355 arranged in a circular array. The end of the multiple air jet pipes 355 near the closed tube 351 corresponds to the plug 352. The end of the multiple air jet pipes 355 away from the closed tube 351 is inclined towards the inside of the brine pot 2, so that the airflow can blow and stir the brine in all directions.

[0034] When the blower 31 is working, the airflow enters the annular pipe 33 through the diverter pipe 32 and the horizontal pipe 34. The airflow pressure pushes the plug 352 to move away from the annular pipe 33, compressing the spring 353. At this time, the plug 352 separates from the plug ring 354, and the airflow enters the closed pipe 351 and is sprayed out into the brine pot 2 through multiple jet pipes 355, forming an annular airflow that blows the brine into a frothy state, cools the brine, and stirs the brine in all directions. When the blower 31 stops working, the spring 353 returns to its original position, pushing the plug 352 and the plug ring 354 to fit tightly together, achieving a seal and preventing the brine from contaminating the annular pipe 33 and the blower 31, while also preventing the nozzle from clogging.

[0035] like Figure 1-12 As shown, in the preferred embodiment, the cooling structure 5 includes multiple L-shaped plates 51 that are detachably bolted to the bottom wall of the cooling tank 4. The multiple L-shaped plates 51 are arranged in a circular array to fix the spiral cooling pipe 52.

[0036] A spiral cooling pipe 52 is fixed between the inner sides of multiple L-shaped plates 51. The spiral cooling pipe 52 is made of copper pipe, which has high thermal conductivity. The inlet of the spiral cooling pipe 52 is connected to the end of the first connecting pipe 21 away from the brine pot 2, and the outlet of the spiral cooling pipe 52 is connected to the end of the second connecting pipe 61 away from the filter box 6. When the heated brine passes through the spiral cooling pipe 52, it fully exchanges heat with the cooling medium in the cooling tank 4 to achieve rapid cooling.

[0037] The cooling structure 5 also includes an inlet pipe 53 connected to the top of the outside of the cooling tank 4, which is used to inject a cooling medium, such as cooling water, into the cooling tank 4. An outlet pipe 54 is connected to the bottom of the outside of the cooling tank 4, which is used to discharge the heated cooling medium, realize the circulation and replacement of the cooling medium, and ensure the cooling effect. Valves are provided on both the inlet pipe 53 and the outlet pipe 54 to facilitate the control of the entry and exit of the cooling medium.

[0038] like Figure 1-12 As shown, in the preferred embodiment, the filter structure 7 includes multiple filter plates 71 disposed inside the filter box 6, preferably three filter plates 71. The filter holes of the multiple filter plates 71 decrease in size from top to bottom, thereby realizing multi-stage filtration of the brine and gradually removing large particulate impurities, fine impurities and suspended solids from the brine from top to bottom, thus improving the filtration effect.

[0039] A support assembly 72 is provided on the outer side of the filter plate 71 to support and limit the filter plate 71, facilitating the installation and disassembly of the filter plate 71. A cover plate 73 is detachably connected to the front of the filter box 6 by bolts. A rubber sealing gasket is provided on the back of the cover plate 73 and the front of the filter box 6 to ensure the airtightness of the filter box 6 and prevent brine leakage. A handle 74 is fixed on the front of the cover plate 73 to facilitate the installation and disassembly of the cover plate 73, thereby facilitating the cleaning and replacement of the filter plate 71.

[0040] like Figure 1-12 As shown, in the preferred embodiment, the support assembly 72 includes fixing blocks 721 fixed to the left and right side walls of the inner cavity of the filter box 6. Each of the two fixing blocks 721 has a support groove 722 on its opposite side. The front of the support groove 722 is connected to the outside. Each side of the filter plate 71 is fixed with a support block 723 that is slidably connected to the inside of the support groove 722. The filter plate 71 can slide along the support groove 722 through the support block 723 to achieve quick installation and disassembly, which is convenient for maintenance.

[0041] like Figure 1-12 As shown, in the preferred embodiment, the reflux structure 9 includes a pump body 91 fixed to the top of the storage tank 8. The inlet of the pump body 91 is connected to a water suction pipe 92. The end of the water suction pipe 92 away from the pump body 91 is connected to the bottom of the outer side of the storage tank 8 for extracting brine from the storage tank 8. The outlet of the pump body 91 is connected to a return pipe 93. The end of the return pipe 93 away from the pump body 91 is connected to the top of the outer side of the brine pot 2 for returning the extracted brine to the brine pot 2, thereby realizing the recycling of brine, reducing the cost of brine, ensuring the consistency of brine concentration, and improving the quality of nut braising.

[0042] like Figure 1-12 As shown, in the preferred embodiment, the bottom horizontal positions of both the filter box 6 and the cooling tank 4 are higher than the bottom horizontal position of the storage tank 8. By utilizing gravity, the cooled brine automatically flows into the filter box 6, and the filtered brine automatically flows into the storage tank 8, requiring no additional power and saving energy.

[0043] A valve is installed on the first connecting pipe 21 to control the flow of brine from the brine pot 2 to the cooling tank 4. When not braising, the valve can be closed directly to prevent brine from flowing to the cooling tank 4.

[0044] The inner top of the brine pot 2 is detachably connected to an installation ring 22 by bolts. A protective net 23 is fixed inside the installation ring 22. The annular tube 33 and the one-way nozzle 35 are located outside the protective net 23. When nuts are placed inside the brine pot 2, the protective net 23 is used to prevent the nuts from contacting the annular tube 33 and the one-way nozzle 35, protecting the annular tube 33 and the nozzle from damage and extending the service life of the equipment.

[0045] Working principle: When using the brine preparation equipment for this nut brine, the nuts that have been fully steamed and cooked are placed into the brine pot through a cloth bag or fine metal mesh to ensure that the nuts are completely submerged in the brine. When the blower 31 is turned on, the airflow generated by the blower 31 enters the annular pipe 33 through the diverter pipe 32 and the horizontal pipe 34. The airflow pressure pushes the plug 352 to move away from the annular pipe 33, compressing the spring 353. The plug 352 separates from the plug ring 354, and the airflow enters the closed pipe 351 and is sprayed out into the brine pot 2 through multiple jet pipes 355, forming an annular airflow to blow the brine into a frothy state, lower the temperature of the brine, and at the same time stir the brine in all directions, so that the brine ingredients and brine are fully mixed. When the braising process begins, the valve on the first connecting pipe 21 is opened. The braising liquid that is heated during the braising process enters the spiral cooling pipe 52 through the first connecting pipe 21. The cooling water in the cooling tank 4 exchanges heat with the high-temperature braising liquid in the spiral cooling pipe 52, causing the braising liquid temperature to drop rapidly. The cooled braising liquid flows into the filter box 6 through the second connecting pipe 61. During the cooling process, the valves of the inlet pipe 53 and the outlet pipe 54 are opened to achieve the circulation and replacement of the cooling medium, so as to avoid the cooling medium temperature from being too high and to ensure the cooling effect. The cooled brine enters the filter box 6 through the second connecting pipe 61. In the filter box 6, the cooled brine is filtered through multiple filter plates 71 in sequence. The uppermost filter plate 71 removes large particulate impurities in the brine, such as brine residue. The middle filter plate 71 removes medium-sized impurities. The lowermost filter plate 71 removes fine impurities and suspended matter. The filtered qualified brine flows into the storage box 8 through the third connecting pipe 81 for storage. While opening the valve of the first connecting pipe 21, the pump body 91 is started. The pump body 91 draws the filtered brine from the storage tank 8 through the water pumping pipe 92, and then transports the brine to the brine pot 2 through the return pipe 93, so as to realize the recycling of brine.

[0046] Example 2: A method for using a braising equipment for nut-based marinades includes the following steps: S1. After steaming and boiling, put the nuts that are to be braised into the brine pot through a cloth bag or fine metal mesh, ensuring that the nuts are completely submerged in the brine; S2. Start the blower 31. The airflow generated by the blower 31 enters the annular pipe 33 through the diverter pipe 32 and the horizontal pipe 34. The airflow pressure pushes the plug 352 to move away from the annular pipe 33, compressing the spring 353. The plug 352 separates from the plug ring 354. The airflow enters the closed pipe 351 and is sprayed out into the brine pot 2 through multiple jet pipes 355, forming an annular airflow to blow the brine, reduce the temperature of the brine, and at the same time stir the brine in all directions, so that the brine ingredients and brine are fully mixed. S3. When the braising process begins, open the valve on the first connecting pipe 21. The braising liquid that is heated during the braising process enters the spiral cooling pipe 52 through the first connecting pipe 21. The cooling water in the cooling tank 4 exchanges heat with the high-temperature braising liquid in the spiral cooling pipe 52, causing the braising liquid temperature to drop rapidly. The cooled braising liquid flows into the filter box 6 through the second connecting pipe 61. S4. During the cooling process, open the valves of the inlet pipe 53 and the outlet pipe 54 to achieve the circulation and replacement of the cooling medium, avoid the cooling medium temperature from being too high, and ensure the cooling effect; S5. The cooled brine will enter the filter box 6 through the second connecting pipe 61. The cooled brine will be filtered through multiple filter plates 71 in the filter box 6. The uppermost filter plate 71 removes large particles of impurities in the brine, such as brine residue. The middle filter plate 71 removes medium-sized particles of impurities. The lowermost filter plate 71 removes fine impurities and suspended matter. The filtered qualified brine flows into the storage box 8 through the third connecting pipe 81 for storage. S6. While opening the valve of the first connecting pipe 21, start the pump body 91. The pump body 91 draws the filtered brine from the storage tank 8 through the water pumping pipe 92, and then transports the brine to the brine pot 2 through the return pipe 93 to realize the recycling of brine.

A protective net (23) is fixed inside the installation ring (22). The ring pipe (33) and the one-way nozzle (35) are located outside the protective net (23).

10. A method of using a braising device for nut-based brining, as described in claim 1, characterized in that: Includes the following steps: S1. After steaming and boiling, put the nuts that are to be braised into the brine pot through a cloth bag or fine metal mesh, ensuring that the nuts are completely submerged in the brine; S2. Start the blower (31). The airflow generated by the blower (31) enters the annular pipe (33) through the diverter pipe (32) and the horizontal pipe (34). The airflow pressure pushes the plug (352) to move away from the annular pipe (33), compressing the spring (353). The plug (352) separates from the plug ring (354). The airflow enters the closed pipe (351) and is sprayed into the inside of the brine pot (2) through multiple jet pipes (355), forming an annular airflow to blow the brine, reduce the temperature of the brine, and at the same time stir the brine in all directions, so that the brine ingredients and brine are fully mixed. S3. When the braising process begins, open the valve on the first connecting pipe (21). The braising liquid heated during the braising process enters the spiral cooling pipe (52) through the first connecting pipe (21). The cooling water in the cooling tank (4) exchanges heat with the high-temperature braising liquid in the spiral cooling pipe (52), causing the braising liquid temperature to drop rapidly. The cooled braising liquid flows into the filter box (6) through the second connecting pipe (61). S4. During the cooling process, open the valves of the inlet pipe (53) and the outlet pipe (54) to realize the circulation and replacement of the cooling medium, avoid the cooling medium temperature from being too high, and ensure the cooling effect; S5. The cooled brine will enter the filter box (6) through the second connecting pipe (61). The cooled brine will be filtered through multiple filter plates (71) in the filter box (6). The uppermost filter plate (71) removes large particles of impurities in the brine, such as brine residue. The middle filter plate (71) removes medium-sized particles of impurities. The lowermost filter plate (71) removes fine impurities and suspended matter. The qualified brine after filtration flows into the storage box (8) through the third connecting pipe (81) for storage. S6. While opening the valve of the first connecting pipe (21), start the pump body (91). The pump body (91) draws the filtered brine in the storage tank (8) through the water pumping pipe (92), and then transports the brine to the brine pot (2) through the return pipe (93) to realize the recycling of brine.
