[0002] Fried food is a way of processing food. It is prepared by placing food into heated cooking oil and frying it with the oil. Fried food is popular because of its crispy texture, delicious taste, and easy preservation of nutrients. Fried food can be divided into high-temperature frying and vacuum low-temperature frying according to the oil temperature. Food fried by vacuum low-temperature frying has a low oil content, so its usage rate is higher than that of high-temperature fried food.

DETAILED DESCRIPTION

[0025] The technical solutions 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.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0028] like Figures 1 to 4 As shown, a continuous vacuum low-temperature fryer for food processing of the present invention includes an oil storage barrel, which is annular in shape and has a circular cross-section along the annular axis. The oil storage barrel is composed of an annular groove plate 1 and an annular sealing plate 2. The annular groove plate 1 is located outside the annular sealing plate 2 and is rotatably sealed to the annular sealing plate 2. A loading and unloading port 3 is provided on the top of the annular groove plate 1, and a negative pressure pipe 4 is connected to the side wall of the annular groove plate 1.

[0029] A plurality of partitions 5 are provided on the side wall of the annular sealing plate 2 on the inner side of the annular groove plate 1. The surface of the partition 5 is along the radial direction of the annular oil storage barrel. The partition 5 divides the internal space of the oil storage barrel, thereby forming a sealed space between two adjacent partitions 5. The outer wall of the partition 5 is in sliding contact with the inside of the annular groove plate 1. A net barrel 6 is provided on the partition 5, and the inside of the net barrel 6 is used to store food to be fried.

[0030] Specifically, low-temperature edible oil is stored in the oil storage barrel, and the liquid level of the edible oil is below the axis of the annular oil storage barrel. The negative pressure pipe 4 is used to extract the air between the two adjacent partitions 5 in the annular groove plate 1, thereby forming a vacuum negative pressure state between the two adjacent partitions 5. When the annular sealing plate 2 rotates, the annular sealing plate 2 can rotate on the annular groove plate 1, and the annular sealing plate 2 and the annular groove plate 1 maintain a sealed state. The annular sealing plate 2 drives the multiple partitions 5 and multiple net barrels 6 thereon to rotate synchronously. When frying food, first rotate the annular sealing plate 2 and move the partition 5 and the net barrel 6 to the position of the take-out port 3, put the food into the net barrel 6, and continue to rotate the annular sealing plate 2, so that the net barrel 6 carries the food into the annular groove plate 1. 5 divides the internal space of the oil storage barrel, so when two adjacent partitions 5 are both located inside the annular groove plate 1, the air between the two adjacent partitions 5 is separated from the air outside the annular groove plate 1. At this time, the air between the two adjacent partitions 5 is extracted through the negative pressure pipe 4, so that a vacuum negative pressure state is formed between the two adjacent partitions 5, that is, the food stored in the net barrel 6 is in a vacuum negative pressure state. When the food moves into the oil stored in the annular groove plate 1, the oil can fry the food. At this time, the food is vacuum-fried at low temperature. After the food moves out of the oil and moves to the position of the take-out port 3 following the annular sealing plate 2, the fried food is taken away and the next group of food is placed in the net barrel 6, thereby achieving a continuous vacuum frying working effect.

[0031] Due to the structural form of the annular sealing plate 2 and the plurality of partitions 5, the space between two adjacent partitions 5 inside the annular groove plate 1 can be conveniently kept in a vacuum and low-temperature state at all times. Therefore, during the cyclic frying process, each net barrel 6 entering the annular groove plate 1 and the food inside the net barrel 6 can be kept in a vacuum and negative pressure state at all times, thereby achieving the working effect of air pressure isolation and continuous vacuum and low-pressure frying.

[0032] By adopting a method of cyclically rotating multiple partitions 5 and forming an independent space between two adjacent partitions 5, the food in the space can be conveniently placed in a vacuum negative pressure state and subjected to low-temperature frying in this state, thereby realizing continuous vacuum low-temperature frying of the food, improving work efficiency, simplifying the operation method, and improving the continuity and airtightness of the vacuum environment.

[0033] More preferably, the bottom of the annular groove plate 1 is connected to a sub-tank 7, and the sub-tank 7 stores an electric heater capable of heating the oil.

[0034] Specifically, by providing the auxiliary box 7, the space on the lower side of the annular groove plate 1 can be in a connected state. Even when the partition 5 moves to this position, the space on the lower side of the annular groove plate 1 is still connected, so that the oil on the left and right sides of the partition 5 can flow to each other, making it convenient for the oil to always be stored on the lower side of the annular groove plate 1, avoiding the partition 5 pushing the oil to move synchronously to the position of the take-in and release port 3 and causing the annular groove plate 1 to be unable to store the oil normally. Since each group of adjacent two partitions 5 in the annular groove plate 1 is in a negative pressure state, even if the space on the lower side of the annular groove plate 1 is connected, it does not affect the vacuum negative pressure environment. By providing an electric heater in the auxiliary box 7, the oil stored in the auxiliary box 7 and the lower side of the annular groove plate 1 can be heated.

[0035] More preferably, a constant pressure structure is provided on the negative pressure tube 4, and the constant pressure structure is used to make the negative pressure values ​​between each group of two adjacent partitions 5 equal;

[0036] The constant pressure structure includes a ventilation pipe 8 installed on the outer wall of the negative pressure pipe 4. The length direction of the ventilation pipe 8 is along the radial direction of the negative pressure pipe 4. The ventilation pipe 8 is connected to the negative pressure pipe 4. A sealing column 9 is slidingly provided in the ventilation pipe 8. The end of the sealing column 9 facing the negative pressure pipe 4 is set to a spherical shape, which can contact the inner wall of the negative pressure pipe 4 through the spherical surface, thereby sealing the inside of the negative pressure pipe 4. A sliding opening is provided on the side wall of the sealing column 9, and the sliding opening extends to the end face of the sealing column 9 away from the negative pressure pipe 4. A horizontal pipe 10 is slidingly provided in the sliding opening. The sliding direction of the horizontal pipe 10 is along the axial direction of the ventilation pipe 8. The opening of the horizontal pipe 10 contacts the inner wall of the ventilation pipe 8, thereby sealing the opening of the horizontal pipe 10 through the inner wall of the ventilation pipe 8. A vertical pipe 11 is connected to the horizontal pipe 10, and the length direction of the vertical pipe 11 is along the axial direction of the ventilation pipe 8;

[0037] The cross pipe 10 and the vent pipe 8 are elastically connected via a spring 12 , and the cross pipe 10 and the sealing column 9 are elastically connected via a spring sheet.

[0038] Specifically, in the natural state, the spring 12 pulls the sealing column 9 away from the negative pressure tube 4 through the cross tube 10 and the spring piece. At this time, the negative pressure tube 4 is connected to the space between the two adjacent partitions 5 in the annular groove plate 1. The negative pressure tube 4 draws out the air between the two adjacent partitions 5, and the inside of the negative pressure tube 4 is in a negative pressure state. Due to the effect of the external atmospheric pressure, the sealing column 9, the cross tube 10 and the vertical tube 11 move synchronously toward the negative pressure tube 4. When the spherical surface of the sealing column 9 enters the negative pressure tube 4 and contacts the inner wall of the negative pressure tube 4, the sealing column 9 blocks the communication relationship between the negative pressure tube 4 and the space between the two adjacent partitions 5. At this time, the negative pressure value between the two adjacent partitions 5 reaches the specified value, and at this time, the opening of the cross tube 10 is still in contact with the inner wall of the ventilation pipe 8, and the ventilation pipe 8 and the negative pressure tube 4 are still in an isolated state. As the air inside the negative pressure tube 4 The pressure drops, and the external atmospheric pressure gradually pushes the cross tube 10 to move in the sliding mouth toward the negative pressure tube 4, and the cross tube 10 gradually moves into the negative pressure tube 4. At this time, the opening of the cross tube 10 is connected with the negative pressure tube 4, that is, the negative pressure tube 4 can be connected with the external air through the cross tube 10 and the vertical tube 11, and the external air can enter the negative pressure tube 4. When the next group of two adjacent partitions 5 move to the position of the negative pressure tube 4, since the air pressure between the two partitions 5 of this group is at normal pressure, it can generate pressure on the spherical surface of the sealing column 9, and the sealing column 9 can be moved back into the ventilation pipe 8 with the help of the spring 12 and the shrapnel. At this time, the ventilation pipe 8 is isolated from the negative pressure tube 4, and the space between the negative pressure tube 4 and the two adjacent partitions 5 is connected, thereby achieving the purpose of constant-pressure exhaust, and conveniently keeping the air pressure value between the two adjacent partitions 5 within the specified range.

[0039] More preferably, a swivel 13 is rotatably provided on the partition 5, and the net barrel 6 is fixed on the swivel 13, so that the net barrel 6 and the food in the net barrel 6 can be turned over in the oil by rotating the swivel 13.

[0040] Specifically, by turning the net barrel 6 and the food inside it, the foods can be separated from each other and fully contacted with the oil, so that the oil can fully fry the food and improve the uniformity of the frying process. At the same time, when the food is separated from the oil, the food can be rotated to achieve the purpose of automatic oil drainage, so that the excess oil on the food falls back into the lower side of the annular groove plate 1.

[0041] More preferably, side plates 14 are provided on the front and rear sides of the outer wall of the annular groove plate 1, and a support shaft 15 is fixed between the two side plates 14. A rotating sleeve 16 is rotatably mounted on the front and rear sides of the outer wall of the support shaft 15. A plurality of connecting arms 17 are provided on the outer wall of the rotating sleeve 16. The connecting arm 17 is fixedly connected to the annular sealing plate 2. A worm gear 18 is fixed to the middle part of the support shaft 15, and a plurality of worms 19 are meshed on the outer wall of the worm gear 18. The end of the worm 19 passes through the annular sealing plate 2 and extends into the annular groove plate 1, and the worm 19 is rotatably connected to the annular sealing plate 2. A first bevel gear 20 is fixed to the end of the worm 19 on the inner side of the annular groove plate 1;

[0042] Bevel teeth are provided on the circumferential outer wall of the rotating ring 13 , and the first bevel gear 20 is meshed and connected with the bevel teeth on the rotating ring 13 .

[0043] Specifically, by rotating the rotating sleeve 16, the rotating sleeve 16 can drive the connecting arm 17 and the annular sealing plate 2 to rotate, thereby providing power for the annular sealing plate 2, and when the annular sealing plate 2 rotates, the annular sealing plate 2 can drive the worm 19 to rotate around the worm wheel 18. Since the worm wheel 18 is meshed and connected with the worm 19, and the support shaft 15 and the worm wheel 18 are in a stationary state, the worm 19 rotates on the worm wheel 18, and the worm 19 can drive the rotating ring 13 to rotate through the first bevel gear 20, thereby providing power for the self-rotation of the net barrel 6, realizing the working effect of synchronous movement of the annular sealing plate 2 and the net barrel 6, and this effect can be achieved by simply providing power to the rotating sleeve 16, and the side plate 14 can support the support shaft 15.

[0044] More preferably, auxiliary rings 21 are rotatably provided on the front and rear end surfaces of the worm wheel 18 , a plurality of support plates 22 are fixed between the two auxiliary rings 21 , and the worm 19 is rotatably mounted on the support plates 22 toward the end surface of the worm wheel 18 .

[0045] Specifically, by providing the auxiliary ring 21 and the support plate 22, the worm 19 can be conveniently supported and connected, so that the worm 19 and the worm wheel 18 can always remain in a meshing state, avoiding the worm 19 from shaking and disengaging from the worm wheel 18. When the worm 19 rotates, the end face of the worm 19 rotates on the support plate 22. When the worm 19 rotates around the support shaft 15, the worm 19 can drive the auxiliary ring 21 to rotate on the worm wheel 18 through the support plate 22.

[0046] More preferably, the partition 5 is provided with a material port, through which food can be put into the net bucket 6 or food in the net bucket 6 can be taken out. The material port is encapsulated with a cover plate 23, and a material guide groove 24 is provided on the side wall of the partition 5, and the material guide groove 24 is close to the material port.

[0047] Specifically, by providing the guide trough 24, the food can be conveniently diverted and the food can be easily taken out and placed.

[0048] More preferably, it also includes a motor 25, which is installed on the side wall of a side plate 14. The output end of the motor 25 is driven by a second bevel gear 26, and the second bevel gear 26 is meshed with a third bevel gear 27. The third bevel gear 27 is fixed on a rotating sleeve 16.

[0049] Specifically, the motor 25 can provide power to the rotating sleeve 16 through the second bevel gear 26 and the third bevel gear 27 .

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
