Technical Field

[0001] The utility model relates to the technical field of pecan kernel processing, in particular to a pecan kernel boiling and astringency removal device. Background Art

[0002] Pecans are a unique nut variety in China with a distinctive flavor. They are primarily cultivated in Ningguo, Anhui Province, and Lin'an, Zhejiang Province, in the Tianmu Mountains. They are a protected geographical indication product. Pecan kernels are nutritious, rich in trace elements and unsaturated fatty acids. They are rich in minerals such as calcium, iron, potassium, and selenium, which can strengthen bones and improve iron-deficiency anemia. Pecan kernels are rich in linoleic acid, which can lower cholesterol levels, protect against cardiovascular and cerebrovascular diseases, and moisturize the intestines.

[0003] Walnut kernels need to be boiled in water during the processing. Boiling can effectively remove the astringency of the walnut kernels themselves. In order to facilitate the boiling operation, control the water temperature, quantity and water adding time, and ensure the boiling effect of the walnut kernels, a device for boiling pecan kernels is needed.

DETAILED DESCRIPTION

[0015] Example 1

[0016] like Figures 1 to 4As shown, the utility model is a device for boiling and removing astringency of pecan kernels. The middle part of the inner cavity of the boiling barrel 1 is divided into an upper heating water tank 105 and a lower heating water tank 106 by an upper heating partition 102 and a leakage plate 103. The leakage plate 103 is located below the upper heating partition 102. A side sealing door 101 is installed on the side of the lower heating water tank 106. The bottom of the lower heating water tank 106 is fixedly installed with a lower heating partition 104 above the bottom plate of the boiling barrel 1. A first electric heating wire 9 is installed at the bottom of the upper heating partition 102. Downpipes 11 are evenly arranged and installed on the upper heating partition 102. At least four water pipes 11 are arranged to make the drainage process more uniform. A solenoid valve is installed on the drainage pipe 11, and its two ends are respectively connected to the upper heating water tank 105 and the lower heating water tank 106. A second heating wire 10 is installed at the bottom of the lower heating plate 104, forming two upper heating water tanks 105 and lower heating water tanks 106 that can be heated independently, which can preheat the water. The solenoid valve is controlled to open the drainage pipe 11 to allow the water in the upper heating water tank 105 to be discharged into the lower heating water tank 106. During the drainage process, the water can be evenly sprinkled into the lower heating water tank 106 through the leak plate 103.

[0017] The top of the side of the water boiling bucket 1 is connected to the upper heating water tank 105 via a water inlet pipe 2, and the bottom of the side is connected to the lower heating water tank 106 via a water outlet pipe 3. Solenoid valves are installed on both the water inlet pipe 2 and the water outlet pipe 3. By controlling the solenoid valves, the water inlet pipe 2 can be controlled to add water to the upper heating water tank 105, and the water outlet pipe 3 can be controlled to discharge waste water from the lower heating water tank 106. A safety valve 4 is installed on the side of the water boiling bucket 1, and the safety valve 4 is connected to the upper heating water tank 105 to ensure safety when heating water in the upper heating water tank 105. A first temperature sensor 5 is installed in the inner cavity of the upper heating water tank 105, and a second temperature sensor 6 is installed in the inner cavity of the lower heating water tank 106. The temperature displays of the first temperature sensor 5 and the second temperature sensor 6 are respectively fixedly mounted on the outer wall of the boiling barrel 1. The first temperature sensor 5 and the second temperature sensor 6 can monitor the water temperature in the upper heating water tank 105 and the lower heating water tank 106 in real time. A first water level sensor 12 and a second water level sensor 13 are installed in an upper and lower arrangement on the inner wall of the upper heating water tank 105, which are used to control the amount of water added to the upper heating water tank 105. The height from the first water level sensor 12 to the upper heating baffle 102 is five times the height from the second water level sensor 13 to the upper heating baffle 102. The amount of water added to the first water level sensor 12 is five times the amount of water added to the second water level sensor 13. This allows different water intake amounts to be controlled according to the boiling process of the pecan kernels, thereby ensuring the boiling effect while effectively saving water.

[0018] A main control module 7 is installed on the outer wall of the water boiling barrel 1, and the main control module 7 is electrically connected to the solenoid valves on the water inlet pipe 2, the water outlet pipe 3, and the downpipe 11, and is electrically connected to the first temperature sensor 5, the second temperature sensor 6, the first heating wire 9, the second heating wire 10, the first water level sensor 12 and the second water level sensor 13, respectively. A material barrel 8 is placed on the lower heating partition 104 in the inner cavity of the lower heating water tank 106. Leakage holes are evenly opened on the material barrel 8, and a barrel cover 801 is provided on the top thereof, which is convenient for placing pecan kernels into the material barrel 8 and soaking them in hot water. The width of the side sealing door 101 is greater than the diameter of the material barrel 8, which is convenient for taking the material barrel 8 out of the water boiling barrel 1.

[0019] The working principle of the utility model is as follows: open the side sealing door 101, take the material barrel 8 out of the boiling barrel 1, open the barrel cover 801, put the pecan kernels to be boiled into the material barrel 8, cover the barrel cover 801 and put them back into the boiling barrel 1, and close the side sealing door 101. The main control module 7 controls the solenoid valve on the water inlet pipe 2 to open, the solenoid valve on the downpipe 11 to close, and the water tank 105 is heated upward. When the first water level sensor 12 detects the water level, the water inlet pipe 2 is closed to stop water injection, the first electric heating wire 9 is turned on to heat the water to 40°C, and then the outlet pipe 3 is kept at 40°C. The solenoid valve on the upper heating water tank is closed, and the solenoid valve on the lower water pipe 11 is opened to allow the hot water in the upper heating water tank 105 to be evenly sprinkled into the lower heating water tank 106 through the leak plate 103. After the water is released, the second heating wire 10 is turned on for insulation heating for 30 minutes, and the pecan kernels in the material barrel 8 are soaked in warm water. At the same time, the water inlet pipe 2 is opened and the lower water pipe 11 is closed, and water is continued to be added to the upper heating water tank 105. When the water level reaches the first water level sensor 12, the water inlet pipe 2 is closed to stop water injection, and the first heating wire 9 is turned on to heat the water in the upper heating water tank 105 to 100°C. After the 40°C water has been kept warm in the lower heating water tank 106 for 30 minutes, the solenoid valve on the water outlet pipe 3 is opened to drain the water and close the water outlet pipe 3. The solenoid valve on the lower water pipe 11 is opened again, and the 100°C hot water in the upper heating water tank 105 is poured into the lower heating water tank 106. The second heating wire 10 is turned on to continue heating for another 30 minutes. Simultaneously, the water inlet pipe 2 is opened again, the lower water pipe 11 is closed, and water is added to the upper heating water tank 105. When the water level reaches the second water level sensor 13, the water inlet pipe 2 is closed to stop the water filling. After the 100°C water has been kept warm in the lower heating water tank 106 for 30 minutes, the solenoid valve on the water outlet pipe 3 is opened to drain the water and close the water outlet pipe 3. The solenoid valve on the lower water pipe 11 is opened again, and the cold water in the upper heating water tank 105 is evenly sprinkled onto the material barrel 8, cooling the material barrel 8 and the boiled pecan kernels. The side sealing door 101 can then be opened to remove them.
