Description

Technical Field

[0001] The invention belongs to the technical field of food processing devices, and in particular relates to an anti-oxidation frying pan. Background Art

[0002] The frying pan is a commonly used processing device for frying nuts. Traditional frying pans are open and directly exposed to the air. The frying temperature is as high as 150-180℃. The vegetable oil in the raw materials for frying nuts contains a large amount of unsaturated fatty acids, which are chemically active and easily oxidized. When heated at high temperatures, the oxidation rate of oils and fats is faster, and the oxidation rate doubles for every 10 degrees increase in temperature. The oxygen in the air oxidizes at high temperatures when in contact with the oils and fats in the seeds, and the peroxide value increases. Fatty acids can form hydroperoxides when oxidized, which is an irreversible reaction. They are very unstable and will further decompose during storage. The decomposition products have a very unpleasant odor. Oil rancidity can also destroy the nutrients in food and even cause some poisoning symptoms, affecting the product value and shelf life.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example

[0021] like Figures 1 to 4As shown, an anti-oxidation frying pan includes a pot body 10, the pot body 10 is a rotating body, one end of the pot body 10 is open and provided with a matching sealing end cover 11, the other end of the pot body 10 is provided with a pipe 12 connected to the pot body 10, the pipe 12 includes an inner wall 121 and an outer wall 122, the inner wall 121 separates the space in the pipe 12 into an air inlet channel 123 and an air outlet channel 124 that are independent of each other. The pot body 10 and the pipe 12 are sealed and welded, the part of the pipe 12 exposed in the pot body 10 is only provided with an interface end respectively connected with the air inlet channel 123 and the air outlet channel 124, the rest of the part is in a closed state, and the part of the pipe 12 disposed in the pot body 10 is provided with an opening.

[0022] Based on the above technical scheme, when the frying pan of the present invention is working, frying salt and fried nuts in a mass ratio of 3:1 are loaded into the pan body 10 through the opening, and then the opening is sealed with the sealing end cover 11, and then a protective gas, such as CO2, is filled into the pan body 10 through the air inlet channel 123. The property of the protective gas is required to not participate in the oxidation reaction of the vegetable oil. After the protective gas is continuously filled into the pan body 10, the original air in the pan body 10 will be diluted and discharged through the air outlet channel 124. After the inflation is completed, the air inlet channel 123 and the air outlet channel 124 are closed, and frying can be carried out. Since the oxygen in the pan body 10 is discharged and the pan body 10 is in a sealed state during frying, the unsaturated fatty acids in the fried nuts can be effectively prevented from being oxidized, thereby improving the quality and shelf life of the fried nuts products. In addition, since the pan body 10 is in a sealed state during frying, the gas in the pan body 10 expands due to heat, causing the air pressure in the pan body 10 to increase, thereby increasing the frying temperature, which is beneficial to improving the frying efficiency.

[0023] Based on the above description, the applicant can also provide another frying method with better effect: before filling the protective gas into the pot body 10, the interface of the air outlet channel 124 is connected to the air inlet end of the vacuum pump, and the air in the pot body 10 is extracted by the vacuum pump, and most of the air in the roasted nuts tissue can be taken out at the same time, so that the anti-oxidation effect during frying in the wok can be further improved; when vacuuming, the pressure in the pot body 10 is controlled to 0.07Mpa and maintained for 5 minutes; then carbon dioxide is filled to isolate oxygen until the pressure in the pot body 10 returns to normal pressure, and then frying begins. During frying, the temperature rise is controlled at 160-190°C for 5-10 minutes. Water vapor is released once in the middle of the frying process, and water vapor can be released through the interface of the air outlet channel 124; at the end of frying, a little pressure is retained, and the air is released and the door is opened, so that micro-expansion can be achieved, thereby achieving the purpose of loosening the tissue.

[0024] As a further improvement of the above technical solution, Figure 4As shown, the pipe 12 extends to the opening in the pot body 10, and the air outlet of the air inlet channel 123 and the air inlet of the air outlet channel 124 are respectively arranged at opposite ends in the pot body 10. That is, the air outlet of the air inlet channel 123 is arranged at an end close to the sealing end cover 11, and the air inlet of the air outlet channel 124 is arranged at an end away from the sealing end cover 11, or the air outlet of the air inlet channel 123 is arranged at an end away from the sealing end cover 11, and the air inlet of the air outlet channel 124 is arranged at an end close to the sealing end cover 11.

[0025] In this way, when a protective gas such as carbon dioxide is filled into the pot body 10 through the air inlet channel 123, since the air outlet of the air inlet channel 123 is arranged opposite to the air inlet of the air outlet channel 12, the carbon dioxide filled into the pot body 10 later will displace the original air, thereby prompting the oxygen-containing air to enter the air outlet channel 12 from the air inlet of the air outlet channel 12 and be discharged. In this way, through this one pipe 12, it is possible to discharge the oxygen-containing air in the pot body 10 while filling with a protective gas such as carbon dioxide.

[0026] As an embodiment of the pipeline 12, Figure 3 As shown in (a), the outer wall 122 is tubular, the inner wall 121 is plate-shaped, and the inner wall 121 divides the internal space of the outer wall 122 into two independent spaces.

[0027] As another embodiment of the pipeline 12, Figure 3 As shown in (b), the outer wall 122 and the inner wall 121 are both tubular, and the inner wall 121 is arranged inside the outer wall 122. Based on the technical solution, the inner wall 121 is the air outlet channel 12, and the air inlet channel 123 is between the outer wall 122 and the inner wall 121. The air outlet of the air inlet channel 123 is arranged at the opening end away from the pot body 10, and the air outlet of the air inlet channel 123 is provided with a plurality of air outlets, which are evenly distributed in a ring around the axis of the outer wall 122, so that the protective gas sprayed from the air outlet is filled in a sheet shape, which is more conducive to discharging the air in the pot body 10.

[0028] Further, such as Figure 1 As shown, the pot body 10 is further provided with a safety valve 13 connected to the air outlet channel 12. The safety valve 13 is a one-way valve, and a safety pressure can be set. When the air pressure in the pot body 10 rises to exceed the safety pressure, the gas in the pot body 10 will be discharged through the safety valve 13, which can ensure that the external air does not enter the pot body 10 through the air outlet channel 12 during frying, and at the same time ensure that the pressure in the pot body 10 is maintained within a stable and safe range.

[0029] In addition, if Figure 1As shown, a one-way valve 14 connected to the air inlet channel 123 is further provided outside the pot body 10. The gas flow direction of the one-way valve 14 is from the outside of the pot body 10 to the inside of the pot body 10. The advantage of such a setting is that the one-way valve 14 plays two roles. On the one hand, it can be used as a connecting valve body. By connecting the one-way valve 14 to the air pump and the protective gas tank in sequence, protective gases such as carbon dioxide can be directly filled into the pot body 10. On the other hand, when the pot body 10 is working, the pressure inside the pot body 10 is greater than the external atmospheric pressure. The one-way valve 14 is a valve that is conducted based on pressure difference. When the pressure inside the pot body 10 is greater than the pressure outside the pot body 10, the one-way valve 14 becomes a stop valve, which is normally closed under the internal pressure of the pot body 10. In this way, it is only necessary to set the safety pressure of the safety valve 13 to be slightly higher than the normal atmospheric pressure.

[0030] like Figure 1 As shown, a pressure gauge 15 connected to the pipeline 12 is also installed outside the pot body 10. The pressure gauge 15 is used to assist safety monitoring. In addition, since the air inlet channel 123 and the air outlet channel 124 are both connected to the inner cavity of the pot body 10, the pressure gauge 15 can be connected to both the air inlet channel 123 and the air outlet channel 124.

[0031] like Figure 1 As shown, the frying pan further includes a heating box 20 and a support base 30; the support base 30 includes a first support frame 31 and a second support frame 32, the first support frame 31 and the second support frame 32 are respectively arranged at the two ends of the pot body 10, and a group of rollers 33 are installed on the top of the first support frame 31 and the second support frame 32, and a transmission ring 16 tangent to the rollers 33 is fixed to the outside of the two ends of the pot body 10, and the horizontal rotation of the pot body 10 is achieved through the rolling contact between the rollers 33 and the transmission ring 16. Each group of rollers 33 is provided with two, so that the rollers 33 and the support base 30 can support the pot body 10 together with the support base 30 while maintaining the rotation of the pot body 10.

[0032] like Figure 1 As shown, the heating box 20 is arranged between the first support frame 31 and the second support frame 32. A groove is arranged on the top of the heating box 20. Part of the pot body 10 is arranged in the groove. A heating wire is installed in the groove of the heating box 20. The pot body 10 is heated by the heating wire. In this way, as the pot body 10 rotates, it can be evenly heated to fry melon seeds and other roasted food.

[0033] like Figure 2 As shown, the pot body 10 is driven and controlled by the motor 40. A coaxial gear is provided at one end of the pot body 10 close to the pipe 12. A matching gear is installed on the rotor of the motor 40. The two gears are driven by a chain. In order to ensure pressure resistance, the pot body 10 is welded from 5-8 mm manganese steel plates. It has a heavy weight and can be stably placed on the support seat 30 and rotated.

[0034] like Figure 1 As shown, a clamping device is provided outside the sealing end cover 11, and the clamping device includes a screw 111, a hand wheel 112 and a bridge-type bracket 113. One end of the screw 111 is fixedly connected to the sealing end cover 11, and the other end of the screw 111 passes through the bridge-type bracket 113 and the hand wheel 112 in sequence. The hand wheel 112 is installed on the bridge-type bracket 113 and can rotate relative to the bridge-type bracket 113. The contact part between the hand wheel 112 and the screw 111 is equipped with a nut, and the two ends of the bridge-type bracket 113 are connected to the pot body 10; the hand wheel 112 and the bridge-type bracket 113 can be connected in rotation through bearings. In this way, the screw 111 cooperates with the nut in the hand wheel 112 to convert the rotation of the hand wheel 112 into the linear motion of the sealing end cover 11, thereby controlling the opening and closing of the sealing end cover 1.

[0035] like Figure 1 As shown, the pot body 10 is provided with a connecting ear 17, and the two ends of the bridge-shaped bracket 113 are rotatably connected to the connecting ear 17 through a pin. In this way, the bridge-shaped bracket 113 can be removed by pulling out the pin, thereby completely exposing the opening of the pot body 10, which is convenient for providing an open environment for maintenance and other operations.
