Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a brine addition device for the production of tea eggs. Background Technology

[0002] As a traditional Chinese food, the flavor of tea eggs mainly depends on the penetration of the braising liquid. Traditional braising processes usually use a static soaking method, where the braising liquid relies solely on natural diffusion and penetration, resulting in uneven braising. Furthermore, spice residues in the braising liquid (such as tea leaves, star anise, and cinnamon) tend to accumulate, affecting the fluidity of the braising liquid and the release of flavor.

[0003] In existing tea egg production equipment, some methods are used to improve braising efficiency by pumping and circulating braising liquid, but the following problems still exist:

[0004] Brine residue can easily clog pumps: Solid particles in the brine (such as broken tea leaves and spice residue) can easily clog pipes and pumps during circulation. Existing filters or filter cartridges are mostly fixed structures, and after long-term use, the filter holes are easily clogged by residue, reducing circulation efficiency, causing equipment failure, and increasing maintenance costs.

[0005] Therefore, there is an urgent need for a brine additive device that can automatically filter brine residue, prevent clogging, and improve the uniformity of brine circulation. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a brine addition device for the production of tea eggs, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides a brine addition device for tea egg production, including a brine barrel, a feeding hopper connected to the inner cavity of the brine barrel at the bottom, a control metering valve installed in the feeding pipe at the bottom of the feeding hopper, and a pressure relief valve installed at the top of the brine barrel. It also includes:

[0009] A circulation assembly, comprising a brine conveying pump installed on the outer wall of a brine barrel, wherein the output end of the brine conveying pump is connected to a discharge pipe extending into the inner cavity of the brine barrel, and the input end of the brine conveying pump is connected to a feed seat.

[0010] The rotating assembly includes a rotating cylinder detachably and rotatably mounted on one side of the feed seat. One end of the rotating cylinder has a suction chamber, and the outer wall of the rotating cylinder has a plurality of suction holes through the suction chamber. The rotating cylinder is connected to the input end of the brine conveying pump through the suction chamber and the inner cavity of the feed seat.

[0011] Furthermore, the top of the brine barrel is provided with a feeding port, and a top cover is detachably installed inside the feeding port. The pressure relief valve is embedded through and installed on the top cover.

[0012] Furthermore, a fixing component is installed on the outer wall of the brine barrel. The fixing component includes a square plate disposed on one side of the brine barrel, and a first screw is threaded through each of the four corners of the square plate.

[0013] Furthermore, a shaft cylinder is vertically fixedly installed at the center of the square plate near the brine barrel. A shaft rod is slidably inserted into the end of the shaft cylinder away from the square plate. The other end of the shaft rod is fixedly connected to the outer wall of the brine barrel. A second screw is threaded onto the outer wall of the shaft cylinder, which presses against the outer wall of the shaft rod.

[0014] Furthermore, the input end of the brine conveying pump is connected to a feed pipe, and rotating holes are provided through both sides of the feed seat. A storage cavity is provided between the outer ring wall of the feed seat and the inner wall of the rotating hole. A plurality of first feed holes are provided through the inner wall of the rotating hole through the storage cavity. The feed pipe is fixedly connected to the outer ring wall of the feed seat and is connected to the storage cavity.

[0015] Furthermore, the rotating assembly also includes a motor disposed below the brine tank, the output end of the motor being connected to a rotating tube via a coupling, and the outer wall of the rotating tube having several second feed holes extending through the inner cavity.

[0016] Furthermore, a retaining ring is installed at the end of the rotating tube, and a threaded ring is installed on the side of the retaining ring away from the rotating tube. The rotating cylinder is threadedly fitted onto the threaded ring, and the material extraction chamber is connected to the material storage chamber through the retaining ring, the inner cavity of the rotating tube, a number of second feed holes, and a number of first feed holes.

[0017] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0018] 1. The rotating drum rotates continuously during the material extraction process, using centrifugal force to prevent residue from clogging the extraction holes, significantly reducing the pump failure rate. The distribution design of the extraction holes can intercept larger residues while allowing the brine to pass through smoothly, balancing filtration and flowability. The rotating drum can be quickly disassembled and cleaned, adapting to brine environments with high residue content.

[0019] 2. Improved uniformity of braising:

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example 1:

[0034] Reference Figure 1-4This is the first embodiment of the present invention, which discloses a brine addition device for the production of tea eggs. The device includes a brine tank 1 (material: 304 stainless steel, wall thickness 3mm, capacity 200L), a feeding hopper 11 (cone angle 60°, outlet diameter 80mm) connected to the inner cavity of the brine tank 1, a control metering valve 12 (model: DN50 pneumatic butterfly valve, flow rate adjustment range 0-500mL / s) installed in the bottom feeding pipe of the feeding hopper 11, and a pressure relief valve 13 (set pressure 0.25MPa) installed on the top of the brine tank 1. The device also includes:

[0035] The circulation assembly includes a brine delivery pump 31 (power 1.5kW, flow rate 8m³ / h) installed on the outer wall of the brine tank 1. 3 / h), the output end of the brine conveying pump 31 is connected to a discharge pipe 32 (DN40 stainless steel pipe, insertion depth 300mm) that extends into the inner cavity of the brine barrel 1. The input end of the brine conveying pump 31 is connected to a feed seat 34 (inner diameter 65mm). The feed seat 34 is normally fixedly installed inside the tea egg production equipment, such as the inner wall of the steaming pot. The rotating component includes a rotating cylinder 46 (length 400mm, outer diameter 100mm, wall thickness 2mm) that is detachably and rotatably installed at one end of the feed seat 34. One end of the rotating cylinder 46 is provided with a suction chamber (volume 0.5L). The outer wall of the rotating cylinder 46 passes through the suction chamber and is provided with several suction holes (hole diameter 5mm, spirally arranged, hole spacing 15mm). The rotating cylinder 46 is connected to the input end of the brine conveying pump 31 through the suction chamber and the inner cavity of the feed seat 34.

[0036] Example 2:

[0037] Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: the top of the brine barrel 1 has a feeding port (300mm in diameter), and a top cover (with a silicone sealing ring) is detachably installed inside the feeding port. A pressure relief valve 13 is embedded through and installed on the top cover. A fixing assembly is installed on the outer wall of the brine barrel 1. The fixing assembly includes a square plate 21 (10mm thick, 400mm side length) located on one side of the brine barrel 1. A first pressure relief valve 13 is threaded through and installed at each of the four corners of the square plate 21. A screw 22 (M10×50 stainless steel bolt) is used. A shaft cylinder 23 (inner diameter 30mm, wall thickness 5mm) is vertically fixed to the center of the square plate 21 near the brine barrel 1. A shaft rod 24 (diameter 28mm, adjustment range ±50mm) is slidably inserted into the end of the shaft cylinder 23 away from the square plate 21. The other end of the shaft rod 24 is fixedly connected to the outer barrel wall of the brine barrel 1. A second screw 25 (M6×20 set screw) is threaded on the outer barrel wall of the shaft cylinder 23 and presses against the outer wall of the shaft rod 24.

[0038] The input end of the brine conveying pump 31 is connected to the feed pipe 33 (DN32 stainless steel corrugated pipe). The feed seat 34 has rotating holes (40mm in diameter) through both sides. A storage chamber (0.3L in volume) is provided between the outer ring wall of the feed seat 34 and the inner wall of the rotating hole. The inner wall of the rotating hole has several first feed holes (8mm in diameter, 6 evenly distributed) through the storage chamber. The feed pipe 33 is fixedly connected to the outer ring wall of the feed seat 34 and is connected to the storage chamber. The rotating assembly also includes a motor 41 (0.75kW power, 30r / min speed) located below the brine tank 1. The output end of the motor 41 is connected to the rotating pipe 42 (38mm in outer diameter, 2mm in wall thickness) through the coupling. The outer wall of the rotating pipe 42 has several second feed holes 43 (6mm in diameter, 8 evenly distributed circumferentially) through the inner cavity.

[0039] A retaining ring 44 (15mm thick) is installed at the end of the rotating tube 42. A threaded ring 45 (M48×1.5 fine thread) is installed on the side of the retaining ring 44 away from the rotating tube 42. The rotating cylinder 46 is threaded onto the threaded ring 45. The screwing direction of the rotating cylinder 46 is consistent with the rotation direction of the rotating tube 42 to prevent the threaded cylinder 46 from loosening and falling off the threaded ring 45 during the rotation of the rotating tube 42. The material extraction chamber is connected to the material storage chamber through the retaining ring 44, the inner cavity of the rotating tube 42, several second feed holes 43 and several first feed holes.

[0040] The remaining structure is the same as that in Example 1.

[0041] The working process of this device mainly includes four core stages: brine injection, circulation filtration, dynamic anti-clogging, and quantitative dosing. The specific process is as follows:

[0042] 1. Brine Injection Stage

[0043] Step 1: Open the feeding port at the top of the spice container 1 and pour the prepared braising liquid (containing water, soy sauce, tea, spices, etc.) into the inner cavity of the spice container;

[0044] Step 2: Close the top cover of the feeding port and ensure that the pressure relief valve (13) is in normal working condition to maintain the air pressure balance inside the barrel and prevent the hot brine from generating negative pressure or overpressure;

[0045] 2. Brine circulation and dynamic filtration stage

[0046] Step 3: Start motor 41. Motor 41 drives rotating tube 42 to rotate through coupling, which in turn drives rotating cylinder 46 connected by thread to rotate synchronously (recommended speed 20-30 r / min).

[0047] Step 4: The brine delivery pump 31 starts working, drawing the brine from the brine tank 1 through the following path:

[0048] Material extraction path: brine → extraction hole of rotating cylinder 46 → extraction chamber → inner cavity of rotating tube 42 → second feed hole 43 → storage chamber of feed seat 34 → feed pipe 33 → input end of brine conveying pump 31.

[0049] Step 5: After being pressurized by the pump, the brine flows back to the upper part of the brine tank 1 through the discharge pipe 32, forming a closed loop.

[0050] Dynamic blocking mechanism:

[0051] During the rotation of the rotating drum 46, the tea residue adhering to the hole wall is thrown off by the centrifugal force due to the centrifugal force of the material extraction hole on its surface, thus avoiding blockage.

[0052] Larger particles of residue (such as whole tea leaves and spice shells) are intercepted by the extraction hole, allowing only brine containing fine particles to pass through, thus protecting the pump body from damage.

[0053] 3. Anti-clogging and self-cleaning auxiliary process

[0054] Step 6: After a long period of operation, if there are still some residues in the material extraction hole of the rotating drum 46, the machine can be stopped and the threaded ring 45 can be unscrewed, and the rotating drum 46 can be disassembled for manual cleaning or replacement.

[0055] Step 7: The storage chamber of the feed seat 34 can temporarily store some brine to prevent the pump from running dry; the first feed hole and the second feed hole 43 are staggered to further reduce the risk of blockage.

[0056] 4. Quantitative addition of brine stage

[0057] Step 8: During the braising process, when it is necessary to add braising liquid to the egg boiling tank, open the control metering valve 12 at the bottom of the feed hopper 11 and accurately add braising liquid according to the preset flow rate.

[0058] Step 9: Pressure relief valve 13 adjusts the pressure inside the barrel in real time to ensure stable material feeding and avoid inaccurate feeding due to pressure fluctuations.

[0059] 5. Shutdown and Maintenance Phase

[0060] Step 10: After production is completed, turn off motor 41 and brine delivery pump 31, and open hopper 11 to drain the residual brine.

[0061] Step 11: Disassemble the rotating drum 46 and the feed seat 34, rinse the residual brine residue with clean water to ensure there is no blockage before the next use.

[0062] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
