Description

Technical Field

[0001] This utility model relates to the technical field of tiger nut processing equipment, specifically a vacuum frying and dehydration machine for tiger nut processing. Background Technology

[0002] In existing tiger nut processing, vacuum frying dehydration machines are commonly used. However, traditional frying dehydration equipment has several significant drawbacks. First, post-frying cooling is a common problem. Tiger nuts reach high temperatures during frying, typically requiring additional cooling to ensure their texture and safety. This cooling process is time-consuming, severely impacting production continuity and efficiency. Second, the frying oil is prone to oxidation and spoilage. Traditional frying equipment typically opens the sealing system to remove the tiger nuts after frying, allowing outside air to enter the frying chamber. This causes the oil to come into contact with air and oxidize. Oil oxidation not only affects the flavor and quality of the nuts but also significantly shortens the oil's lifespan, increasing the frequency of oil replacement and equipment maintenance costs.

[0003] Furthermore, the problem of oil residue generated during frying urgently needs to be addressed. Existing equipment typically lacks an effective oil residue filtration mechanism, leading to the failure to remove or filter oil residue in a timely manner. This residue easily accumulates in the oil, severely contaminating it. Excessive oil residue not only affects the quality of fried foods but can also cause malfunctions or damage to the frying equipment. Oil residue contamination not only reduces the efficiency of oil utilization but can also affect the taste of nuts and the overall quality of the product. Therefore, oil residue contamination is a major bottleneck in traditional frying and dehydration equipment.

[0004] To address this problem, this invention provides a vacuum frying and dehydration machine for processing tiger nuts. Utility Model Content

[0015] Beneficial effects

[0016] This invention provides a vacuum frying and dehydration machine for processing tiger nuts. Compared with the prior art, it has the following advantages:

[0017] (1) The vacuum frying and dehydration machine for processing tiger nuts uses a vacuum pump to vacuum the frying chamber, which can quickly evaporate the moisture inside the tiger nuts in a vacuum environment, forming a loose and porous structure, greatly improving the dehydration efficiency and shortening the dehydration time. The nitrogen filling mechanism can fill the frying chamber with nitrogen in time after the frying operation is completed. The low-temperature nitrogen can cool the frying chamber. The low-temperature nitrogen can not only quickly reduce the temperature of the frying chamber after the tiger nuts are taken out, but the oil guide pipe can also guide the oil into the oil storage chamber after the frying operation is completed, avoiding the external air from entering the tank after the sealed door is opened, which would cause the oil to come into contact with oxygen and oxidize and deteriorate, extend the service life of the frying oil, reduce the frequency of oil replacement, and thus reduce the production cost.

[0018] (2) The vacuum frying and dehydrating machine for processing tiger nuts can effectively filter the oil residue generated during the frying process by setting up a filter frame and scraper, avoiding the oil residue from depositing in the oil and contaminating the frying oil, and extending the oil's service life. This design not only improves the utilization rate of oil, but also effectively avoids equipment failure or oil quality decline caused by oil residue accumulation, ensuring the stability of product quality. The quick connection and disassembly of the storage mechanism and filter frame make the feeding, taking out and cleaning of tiger nuts more efficient and convenient. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-2 A vacuum frying and dehydration machine for processing tiger nuts, comprising:

[0027] Tank 1, with a bottom plate 2 fixed to the bottom wall of tank 1. The inner cavity of tank 1 is divided into an upper frying chamber 4 and a bottom oil storage chamber 5 by a partition 3. A vacuum pump 6 and a nitrogen tank 8 are installed on one side of the bottom plate 2. The air inlet of the vacuum pump 6 is connected to the upper part of the inner cavity of the frying chamber 4 through a suction pipe 7. The nitrogen tank 8 is connected to the upper part of the inner cavity of the frying chamber 4 through an air inlet pipe 9 with a valve. A spiral pipe 10 connected to external circulating ice water is wound around the outside of the air inlet pipe 9. A heating pipe 11 is embedded inside the tank 1 at the bottom position corresponding to the frying chamber 4. The heating pipe 11 is connected to an external heater. A circulation pump 18 is fixed on the right side of the bottom plate 2. The liquid inlet of the circulation pump 18 is connected to the bottom of the inner cavity of the oil storage chamber 5. The liquid outlet of the circulation pump 18 is connected to the upper part of the inner cavity of the frying chamber 4 through a return oil pipe 19. An oil guide pipe 20 with a solenoid valve is fixedly connected to the partition 3.

[0028] The storage mechanism 13 has a lifting mechanism 14 connected to its top via a connecting mechanism 16. The lifting mechanism 14 is installed on the top of the tank body 1.

[0029] Rotating mechanism 15 is installed on the top of tank 1 and is used to drive storage mechanism 13 to rotate.

[0030] A pressure gauge 12 connected to the frying chamber 4 is installed on the top of the tank body 1, and a sealing door 17 is installed on the front wall of the tank body 1 corresponding to the upper part of the frying chamber 4.

[0031] In this embodiment, a vacuum pump 6 is used to create a vacuum inside the frying chamber 4. Under vacuum, the moisture inside the tiger nuts evaporates rapidly, forming a loose and porous structure, thus achieving dehydration. Simultaneously, a heater and heating tube 11 heat the oil inside the frying chamber 4, enabling the frying of the tiger nuts. A nitrogen tank 8 fills the frying chamber 4 with nitrogen when the tiger nuts need to be removed after frying. Meanwhile, the spiral tube 10 wrapped around the outside of the air inlet pipe 9 continuously circulates ice water, cooling the nitrogen entering the nitrogen tank 8. The low-temperature nitrogen, upon entering the frying chamber 4, effectively cools the frying chamber. 4. Cooling operation is performed so that the tiger nuts do not need to be cooled after they are taken out. The oil guide pipe 20 can guide the oil into the oil storage chamber 5 after the frying operation is completed, so as to prevent the outside air from entering the tank 1 after the sealing door 17 is opened, which would cause the oil to oxidize and deteriorate due to contact with oxygen. The circulation pump 18 can pump the oil in the oil storage chamber 5 back into the frying chamber 4 for the next frying operation. At the same time, in this embodiment, an oil filling pipe and an oil drain pipe (both with valves) connected to the oil storage chamber 5 can be set on the rear wall of the tank 1 to facilitate the periodic replacement of oil. The pressure gauge 12 can be used to easily observe the pressure in the frying chamber 4. The storage mechanism 13 can conveniently store tiger nuts to be fried, while avoiding the filter residue generated during frying, reducing oil contamination and extending the oil's lifespan. The rotating mechanism 15 can drive the storage mechanism 13 to rotate after frying, centrifugally throwing out the residual oil in the storage mechanism 13. The lifting mechanism 14 is used to lift the storage mechanism 13 for easy centrifugal oil removal and can also move the storage mechanism 13 to the sealing door 17 for easy removal. The connecting mechanism 16 can facilitate the quick connection and removal of the lifting mechanism 14 and the storage mechanism 13, making the operation simple and convenient.

[0032] Example 2:

[0033] Please see Figure 2-4 This embodiment provides a technical solution based on Embodiment 1:

[0034] The storage mechanism 13 includes a storage frame 131, a threaded cap 132 screwed to the bottom of the storage frame 131, a top plate 133 fixed to the top of the storage frame 131, a filter frame 134 sleeved on the outside of the storage frame 131, the filter frame 134 being fixed to the bottom wall of the top plate 133 by a screw 135 and a nut, and a scraper 136 fixed to the outer edge of the bottom of the storage frame 131, the scraper 136 being in contact with the inner wall of the filter frame 134.

[0035] In this embodiment, the storage frame 131 is used to store tiger nuts to be fried. The threaded cap 132 facilitates the insertion and removal of tiger nuts. The filter frame 134 filters out oil residue generated during frying, reducing oil contamination and extending the oil's lifespan. When excessive oil residue affects the normal operation of the filter frame 134, the nut on the screw 135 is removed, and the filter frame 134 is pulled downwards. During the pulling process, the scraper 136 scrapes off the oil residue from the inner wall of the filter frame 134, and then the oil residue on the scraper 136 is cleaned.

[0036] The rotating mechanism 15 includes a drive motor 151, which is fixed on the top wall of the tank 1. A drive gear 152 is fixed on the power shaft at the top of the drive motor 151. The drive gear 152 is meshed with a gear ring 153. A rotating tube 154 is fixed in the center of the gear ring 153. The rotating tube 154 is rotatably mounted on the top wall of the tank 1 through a leak-proof bearing.

[0037] The lifting mechanism 14 includes a mounting frame 141, which is fixed to the top wall of the tank 1. A hydraulic cylinder 142 is fixed to one side of the mounting frame 141. A square piston 143 is rotatably mounted on the movable end of the bottom of the hydraulic cylinder 142. The piston 143 is slidably mounted on the inner wall of the rotating tube 154.

[0038] The connecting mechanism 16 includes a connecting rod 161 and a threaded post 164. The connecting rod 161 is fixed to the bottom wall of the piston 143. A threaded sleeve 162 is slidably sleeved on the outer side of the bottom of the connecting rod 161. A first hook 163 is fixed at the bottom end of the connecting rod 161. The threaded post 164 is fixed to the center of the top wall of the top plate 133. The threaded post 164 cooperates with the threaded sleeve 162. A second hook 165 matching the first hook 163 is fixed at the top of the threaded post 164.

[0039] In this embodiment, the rotating mechanism 15 is used to drive the storage mechanism 13 to rotate, realizing the centrifugal operation of the storage mechanism 13 and throwing out the residual oil in the storage mechanism 13. When the rotating mechanism 15 is working, the drive motor 151 drives the rotating tube 154 to rotate through the drive gear 152 and the gear ring 153. During the rotation of the rotating tube 154, the square piston 143 drives the connecting mechanism 16 to rotate, thereby driving the storage mechanism 13 to rotate. The lifting mechanism 14 is used to drive the storage mechanism 13 to move up and down. When it is necessary to lift the storage mechanism 13, the hydraulic cylinder 142 is controlled to retract to drive the storage mechanism 13 to move. The connecting mechanism 16 can facilitate the quick connection and removal of the lifting mechanism 14 and the storage mechanism 13, and the operation is simple and convenient. When it is necessary to remove the storage mechanism 13, rotate the threaded sleeve 162 so that the threaded sleeve 162 disengages from the threaded post 164, and then remove the second hook 165 from the first hook 163.
