Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, specifically a pickling device for processing dried yellow peaches. Background Technology

[0002] In the yellow peach preserve processing industry chain, the pickling process is the core link that determines the product's flavor, texture, and shelf life. Currently, most yellow peach pickling equipment on the market suffers from technological bottlenecks, making it difficult to meet the dual requirements of efficiency and quality in modern production.

[0003] 1. Traditional equipment mainly uses a fixed barrel structure for material holding. The material needs to be put in one by one from the top, and the material needs to be scooped or poured out manually, which takes a long time (the total time for loading and unloading of a 100L capacity equipment exceeds 30 minutes). In addition, the peach pieces are easily squeezed and collided during the unloading process, with a breakage rate as high as 15%-20%.

[0004] 2. To improve the uniformity of pickling, some equipment uses a stirring mechanism to stir the fruit pieces. However, stirring causes great damage to the fruit pulp and there are dead spots in the stirring. In addition, the pickling time is still long, which restricts production efficiency.

[0005] Therefore, there is an urgent need to design a pickling equipment for processing yellow peach preserves that can achieve uniform pickling, high efficiency, quick and convenient discharge, and effectively protect the integrity of the fruit flesh. Utility Model Content

[0006] The technical problem to be solved by this utility model is that existing pickling equipment has low pickling efficiency, inconvenient discharge, and low quality.

[0007] To solve the above problems, the technical solution of this utility model is: a pickling equipment for processing dried yellow peaches, including a tank, the top of which is provided with a top cover, a material barrel is installed inside, a liquid circulation component is connected to the side, and the surface of the material barrel is provided with several water-permeable holes.

[0008] The material barrel is equipped with an inner cover on the top and a conical design at the bottom, and is provided with a discharge pipe. The bottom of the discharge pipe is equipped with a bottom cover, and the lower part of the tank is provided with a support frame for supporting and fixing the material barrel.

[0009] Both sides of the tank are equipped with drain pipes at the bottom. The liquid circulation assembly includes a water pump. The water pump's inlet pipe is connected to one drain pipe. The water pump's outlet pipe is connected to an annular spray pipe installed at the top of the tank via a water delivery pipe. The spray pipe is equipped with several nozzles. The bottom of another drain pipe is connected to a buffer tank via a branch pipe. The buffer tank has an opening at the top of one side and an outlet pipe at the bottom of the other side. The water pump's inlet pipe is connected to the outlet pipe via a connecting pipe.

[0010] Furthermore, the inner cover has several water-permeable holes, and a vertical rod is fixedly connected to its middle. The top of the vertical rod is provided with a circular plate that abuts against the top cover. The bottom inner surface of the top cover is provided with a limiting ring sleeved on the outside of the circular plate. The installation and fixing of the top cover, inner cover and bottom cover are all fixed by threaded connection.

[0011] Furthermore, a filter is installed between the water inlet pipe and the drain pipe of the water pump.

[0012] Furthermore, an auxiliary heater is installed in the middle of the water supply pipe. The auxiliary heater includes a housing, and multiple electric heating wires are installed inside the housing.

[0013] Furthermore, the nozzles are provided in two sets and arranged in a circular array. One set of nozzles sprays the liquid towards the top of the material container, while the other set of nozzles sprays the liquid towards the outside of the material container.

[0014] Furthermore, a cover plate is installed at the opening of the buffer box, and a filter frame is installed on the upper inner part of the buffer box near the opening. The connection between the branch pipe and the buffer box is located inside the filter frame.

[0015] Furthermore, temperature sensors are installed inside both the tank and the buffer box, and an electric heating element is also installed inside the buffer box.

[0016] Furthermore, solenoid valves are installed on the liquid outlet pipe, branch pipe, and two discharge pipes, with the solenoid valve on the discharge pipe located at the end furthest from the tank body.

[0017] The advantages of this utility model compared with the existing technology are as follows: This utility model realizes automatic discharge of fruit pieces through the design of conical bottom material bucket and discharge pipe, shortens the discharge time, and reduces the breakage rate; through the circulation of sugar solution and dynamic pickling cycle, the sugar penetration and water exchange process are greatly accelerated, the pickling time is significantly shortened, and the consistency of product quality is guaranteed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, a pickling device for processing dried yellow peaches includes a tank 1, with a top cover 2 threadedly connected to the top of the tank 1 to ensure sealing while allowing for quick opening. The lower part of the inside of the tank 1 is welded with...

[0024] The support frame 7 is used to support the core component material bucket 3, and the lower part of both sides of the tank body 1 is equipped with drain pipes 8.

[0025] The material bucket 3 is a container that directly holds the dried yellow peaches. Its side walls and bottom are covered with dense permeable holes, the diameter of which is smaller than the size of the dried fruit pieces, ensuring that the sugar syrup can pass freely without the dried fruit leaking out. The bottom of the material bucket 3 has a conical structure, and the angle of the conical slope is designed to ensure that the dried fruit slides naturally towards the center under the action of gravity. The lowest point of the cone bottom is connected to the discharge pipe 5, and the end of the discharge pipe 5 is connected to a detachable bottom cover 6 by a thread. This design realizes the "central gathering and smooth discharge" of the dried fruit, which greatly reduces the blockage and squeezing damage to the dried fruit during the discharge process.

[0026] The material bucket 3 has an inner cover 4 threaded on the top inner side. The inner cover 4 also has a water permeable hole. A vertical rod 16 is fixed vertically at the center of the inner cover 4. A circular plate is provided at the top of the vertical rod 16. After the material is filled, the inner cover 4 is closed, and the material bucket 3 is placed on the support frame 7, the top cover 2 is closed. The inner wall of the top cover 2 will press down to press the circular plate at the top of the vertical rod 16. This design achieves three functions: first, the material is pressed down by the inner cover 4 to prevent it from floating under the impact of liquid flow, ensuring that the yellow peach pieces are completely submerged in the liquid; second, the material bucket 3 is pressed and fixed on the support frame 7 to prevent shaking; and third, the vertical rod 16 acts as a handle, which greatly facilitates the picking up, loading, and cleaning of the material bucket 3.

[0027] The liquid circulation assembly includes a water pump 9, whose inlet pipe is directly connected to a pipe at the bottom of the tank 1.

[0028] The drain pipe 8 is used in the "tank self-circulation" mode, which allows the sugar solution inside the tank to be directly pumped out for circulation. A filter 17 is installed at the inlet of the water pump 9 to remove larger impurities such as fruit pulp fibers from the sugar solution, preventing blockage of the pump and nozzles. The outlet of the water pump 9 is connected to an annular spray pipe 11 installed in the upper part of the tank body 1 via a water supply pipe 10. The spray pipe 11 has several nozzles. An auxiliary heater 18 is integrated into the water supply pipe 10. The auxiliary heater 18 includes a housing with multiple sets of electric heating wires installed inside, which can quickly and precisely heat the flowing sugar solution to meet the temperature requirements of the pickling process.

[0029] After being pressurized and heated, the sugar syrup is transported through the water pipe 10 to the annular spray pipe 11 installed at the top of the tank 1. The spray pipe 11 is equipped with two sets of carefully arranged nozzles: the first set of nozzles faces the upper part of the inside of the material barrel 3, and the second set of nozzles sprays towards the annular space between the outside of the material barrel 3 and the inner wall of the tank 1. This three-dimensional, multi-angle spraying method ensures that the sugar syrup can be added relatively evenly into the inside of the tank 1, improving the uniformity of contact between the yellow peach pieces and the sugar syrup.

[0030] Another drain pipe 8 is connected to the lower part of the other side of the tank 1. The bottom of this drain pipe 8 is connected to the buffer tank 13 via a branch pipe 12. Solenoid valves are installed in the middle of the branch pipe 12 and at the end of the drain pipe 8 away from the tank. The upper part of one side of the buffer tank 13 has an opening and is equipped with an openable cover plate 19. A filter frame 20 is installed inside the buffer tank 13 near the upper part of the opening. The connection port between the branch pipe 12 and the buffer tank 13 is located inside this filter frame 20. In this way, the sugar solution discharged from the tank 1 into the buffer tank 13 must first pass through the fine filtration of the filter frame 20.

[0031] Only then can it fall to the bottom of the box for storage, thereby effectively removing small suspended matter and keeping the sugar solution clear.

[0032] The buffer tank 13 is equipped with a temperature sensor (not shown in the figure) and an electric heating tube 21, which allows the buffer tank 13 to be used as an independent unit for the preparation and preheating of sugar solution, or for the insulation and storage of recycled sugar solution.

[0033] The water inlet pipe of the water pump 9 is also connected to the liquid outlet pipe 14 at the bottom of the buffer tank 13 via the connecting pipe 15. This passage is used to draw sugar solution from the buffer tank 13 and transport it into the tank 1.

[0034] In practical use, the device is operated by an external PLC control system.

[0035] Open the cover 19 of the buffer tank 13, add a sugar solution of 40%-60% concentration to the tank, and close the cover 19; set the target pickling temperature to 25-35℃, start the electric heating tube 21 in the buffer tank 13 to heat the sugar solution to the target temperature, and the temperature sensor monitors and feeds back the data in real time to maintain a constant temperature.

[0036] Open the top cover 2 of tank 1, hold the vertical rod 16 to lift the material bucket 3, open the inner cover 4, peel and pit the pre-treated yellow peach pieces, and put them into the material bucket 3 with a size of 20-30mm. The filling amount should not exceed 80% of the volume. Close the inner cover 4, put the material bucket 3 back on the support frame 7 of tank 1, and close the top cover 2. At this time, the round plate at the top of the vertical rod 16 abuts against the inner wall of the top cover 2, fixing the material bucket 3 and pressing the fruit pieces.

[0037] Open the solenoid valve on the outlet pipe 14 and start the water pump. The sugar solution in the buffer tank 13 enters the water pump 9 through the outlet pipe 14 and the connecting pipe 15, and then is transported to the annular spray pipe 11 through the water supply pipe 10. The two sets of nozzles of the spray pipe 11 spray the sugar solution into the inside and outside of the material tank 3 respectively. The sugar solution permeates the gaps between the fruit pieces through the water permeable holes. When the sugar solution level in the tank 1 reaches the preset height and is 50-100mm above the top of the inner cover 4, close the solenoid valve on the outlet pipe 14 and open the solenoid valve on the drain pipe 8 connected to the water pump 9 to realize the circulation of the sugar solution inside the tank. The auxiliary heater 18 compensates for the temperature loss in real time according to the feedback from the temperature sensor inside the tank 1 to ensure that the temperature difference inside the tank is ≤1℃. The flowing sugar solution and the appropriate soaking temperature effectively improve the soaking efficiency and improve the uniformity of the fruit pieces' flavor.

[0038] To enhance the maceration effect, after maceration for a period of time, the solenoid valves on the water pump 9 and its connected drain pipe 8 are closed, while the solenoid valve on the branch pipe 12 is opened, allowing the sugar solution to flow back into the buffer tank 13. The peach pieces in the material bucket 3 are briefly drained, and then the peach pieces are macerated again using the same method, forming a dynamic maceration cycle. During the initial maceration, the high-concentration sugar solution surrounds the peach pieces, and the sugar diffuses from the high-concentration area on the outside to the low-concentration area inside the pulp through osmosis. When the pieces are lifted to drain, the sugar solution adhering to the surface and shallow layer of the pieces flows back into the sugar solution pool, which temporarily lowers the sugar concentration on the surface of the pieces while the sugar concentration inside the pulp remains relatively high. When the pieces are immersed in the sugar solution again, a large concentration difference is re-established between the surface of the pieces and the external sugar solution. This concentration difference is the fundamental driving force of osmosis, and the new driving force accelerates the penetration of sugar deeper into the pulp, thereby significantly shortening the total time required to reach the target sugar level and ensuring that the sugar level of the inner and outer layers of pulp is consistent.

[0039] After pickling, turn off the water pump 9 and auxiliary heater 18, open the solenoid valve on the branch pipe 12, and discharge the sugar solution in the tank into the buffer tank 13 for recycling and filtration through the filter frame 20; after the sugar solution is drained, take out the material bucket 3, and then open the bottom cover 6 at the bottom of the discharge pipe 5. The fruit pieces are automatically discharged to the receiving equipment below under the guidance of the conical bottom through the discharge pipe 5. The discharge time is 3-5 minutes and the breakage rate is ≤5%.
