Description

Technical Field

[0001] This utility model relates to a fried dough twist machine with a cooling function. Background Technology

[0002] A deep fryer is a device specifically designed for high-temperature frying of food. It can use energy sources such as electricity, natural gas, fuel oil, and biofuels. Deep fryers are very common in food processing, such as for processing foods like fried dough twists and peach crisps.

[0003] When deep-frying twisted dough sticks, a double-frying process is generally required. After the initial frying, the dough sticks are cooled and then deep-fried again to improve the frying effect and taste. Currently, traditional deep fryers are generally designed with only a single frying tank. After frying, the twisted dough sticks are removed and placed in the outside air to cool before being put back into the frying tank for a second frying. This makes the frying process unsustainable and requires waiting, which is not conducive to the batch processing of twisted dough sticks. At the same time, the lack of auxiliary cooling design may result in a long cooling time, thus affecting the overall processing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0027] The utility model will be further illustrated by the following examples, but the utility model is not limited in the scope of the examples.

[0028] For example, Figures 1-6As shown, the fried dough twist fryer with cooling function includes a cylinder 2; it also includes: a dividing mechanism, which is disposed inside the cylinder 2 and divides the inside of the cylinder 2 into a primary frying tank 6, a cooling tank 7, a secondary frying tank 8, and a material changing tank 9 in a clockwise direction; and a lifting and rotating mechanism, which is connected to four material storage net boxes 16, and the four material storage net boxes 16 are arranged in a circular array. The lifting and rotating mechanism is used to drive the material storage net boxes 16 to transfer in the primary frying tank 6, the cooling tank 7, the secondary frying tank 8, and the material changing tank 9.

[0029] Both the primary frying tank 6 and the secondary frying tank 8 are equipped with heating devices, such as heating wires, for heating the oil stored therein. At the same time, temperature sensors are installed in the primary frying tank 6 and the secondary frying tank 8, which are connected to external control equipment for constant temperature control of the oil.

[0030] like Figure 1 and Figure 4 As shown, the separating mechanism includes a column 4 and four partitions 5. The four partitions 5 are fixedly installed in a circular array on the four sides of the column 4, and the end faces and bottom faces of the partitions 5 away from the column 4 are fixed to the inner wall of the cylinder 2. The column 4 is located in the middle of the cylinder 2, and the bottom end of the column 4 is fixed to the bottom inner wall of the cylinder 2. Through the separation, four tanks are formed, namely the initial blasting tank 6, the cooling tank 7, the secondary blasting tank 8, and the material changing tank 9.

[0031] The surface of the cylinder 2 is provided with a through groove 14, which is connected to the material changing trough 9, and a sealing plate 15 is engaged and connected inside the through groove 14. The sealing plate 15 is used to close the through groove 14 after the frying operation is completed. During the frying operation, the sealing plate 15 needs to be removed to cover the through groove 14.

[0032] It also includes a base frame 1, which is fixedly installed at the bottom of the cylinder 2. The base frame 1 is used to elevate the cylinder 2.

[0033] The lifting and rotating mechanism includes an upper frame 3, a circular tube 10, a motor 11, and a lifting assembly. The upper frame 3 is fixedly installed at the top of the cylinder 2. The motor 11 is fixedly installed at the top center of the upper frame 3, and the output shaft of the motor 11 is fixedly connected to the top end of the circular tube 10. The bottom end of the circular tube 10 is rotatably connected to the top end of the column 4. The lifting assembly is installed on the circular tube 10, and four connecting frames 13 arranged in a circular array are connected around the lifting assembly. The bottom of the connecting frames 13 is connected to the storage mesh box 16.

[0034] The lifting assembly is used to drive the connecting frame 13 to move up and down, and adjust the height of the storage mesh box 16, that is, to enter the cylinder 2, or to leave the cylinder 2 and move above the cylinder 2.

[0035] When the storage net box 16 moves above the barrel 2, the motor 11 is driven to rotate the circular tube 10, so that the structure on the circular tube 10 rotates together, and each time the clockwise rotation is 90°, so that the four storage net boxes 16 change positions, that is, a single storage net box 16 can enter the primary explosion tank 6, the cooling tank 7, the re-explosion tank 8 and the material replacement tank 9 in turn, and then circulate back to the primary explosion tank 6.

[0036] The motor 11 can be a servo motor 11 or a stepping motor 11.

[0037] The lifting assembly comprises a cylinder 17 and a sleeve ring 12. The cylinder 17 is vertically arranged and fixedly installed in the interior of the stand column 4. The output end shaft 1701 of the cylinder 17 extends into the interior of the bottom end of the circular tube 10. A disc 20 is fixedly installed at the top end of the output end shaft 1701. An inner disc body 22 is arranged above the disc 20. A vertical groove 1001 is formed in the tube surface of the circular tube 10 and communicates with the interior of the circular tube 10. The inner disc body 22 is connected in clearance fit with the inner wall of the circular tube 10 and the vertical groove 1001. The inner ring surface of the sleeve ring 12 is fixedly connected with the inner disc body 22, and the inner ring surface of the sleeve ring 12 is connected in clearance fit with the outer tube wall of the circular tube 10. The outer ring surface of the sleeve ring 12 is fixedly connected with the top end of the connecting frame 13.

[0038] The lifting drive is provided by the extension and contraction of the cylinder 17. When the cylinder 17 is extended, the disc 20 pushes the inner disc body 22 to move upward, thereby achieving upward movement. When the cylinder 17 is retracted, the disc 20 moves downward. Under the action of gravity, the inner disc body 22 moves downward and is always in contact with the ball bearings 21 on the disc 20.

[0039] A plurality of concave holes are uniformly distributed on the top of the disc 20. Ball bearings 21 are connected in clearance fit in the concave holes. The ball bearings 21 are in contact with the bottom surface of the inner disc body 22.

[0040] Through the design of the ball bearings 21, when the inner disc body 22 rotates together with the circular tube 10, the inner disc body 22 rolls and rubs through the ball bearings 21, thereby reducing the abrasion of the bottom of the inner disc body 22.

[0041] The storage net box 16 comprises a mesh cover 1601, an upper mesh plate 1602, a lower mesh plate 1603 and a hasp lock 1604. The upper and lower openings of the mesh cover 1601 are respectively provided with the upper mesh plate 1602 and the lower mesh plate 1603. The upper mesh plate 1602 and the lower mesh plate 1603 are connected with the mesh cover 1601 through the hasp lock 1604. The outer wall of the mesh cover 1601 is fixedly connected with the bottom end of the connecting frame 13.

[0042] Both the upper and lower parts of the storage net box 16 can be opened, so that the material inside can be replaced. When the material is replaced, the worker needs to wear protective gloves.

[0043] A fan cover 18 is fixedly installed on the barrel wall of the barrel 2, and the two ends of the fan cover 18 are communicated with the outside of the barrel 2 and the cooling groove 7. A plurality of fans 19 are uniformly installed in the inside of the fan cover 18, and the air outlet end of the fan 19 faces the inside of the cooling groove 7. The fan cover 18 is used for providing cooling air blowing.

[0044] Working principle: in the specific implementation, the whole fried dough stick frying machine is connected with a power supply and a control system, which is used for power supply and electric control. The air cylinder 17 needs to be connected with an air source driving device to provide driving. Meanwhile, the sealing plate 15 at the position of the through groove 14 is removed before use to cancel the shielding.

[0045] As shown in Figure 1 Fig. 2, the lifting assembly is in a low position, so that the four storage net boxes 16 are respectively located in the primary frying groove 6, the cooling groove 7, the secondary frying groove 8 and the material changing groove 9. By operating the storage net box 16 in the material changing groove 9, the hasp lock 1604 at the upper net plate 1602 is unlocked, the upper net plate 1602 is removed, the fried dough sticks to be fried are poured into the storage net box 16 through the opening on the storage net box 16, and then the upper net plate 1602 is reinstalled on the storage net box 16 through the hasp lock 1604 to complete the feeding.

[0046] Then the air cylinder 17 is elongated to drive the disc 20 to move upward, the disc 20 drives the inner disc body 22 to move upward, so that the sleeve ring 12 slides upward at the circular tube 10, the sleeve ring 12 drives the connecting frame 13 to move together, the storage net box 16 is pulled out of the barrel 2, and the movement of the inner disc body 22 stops until the inner disc body 22 moves to the top end of the vertical groove 1001. Then the motor 11 drives the circular tube 10 to rotate clockwise by 90°. When the circular tube 10 rotates, the inner disc body 22 rotates together with the circular tube 10, the inner disc body 22 drives the sleeve ring 12, the connecting frame 13 and the storage net box 16 to rotate together, so that the storage net box 16 loaded with the materials moves above the primary frying groove 6. Then the air cylinder 17 is contracted, the disc 20 moves downward, and the inner disc body 22 moves downward together with the disc 20 by gravity, so that the storage net box 16 reenters the barrel 2. The movement of the inner disc body 22 stops until the inner disc body 22 moves to the bottom end of the vertical groove 1001. The materials are preliminarily fried by the hot oil in the primary frying groove 6. In the process of the preliminary frying, the storage net box 16 moved to the material changing groove 9 is manually fed.

[0047] After the preliminary frying, the lifting assembly drives the storage net box 16 to move upward and away from the inside of the barrel 2. Then the motor 11 drives the clockwise rotation by 90°, so that the preliminarily fried materials move above the cooling groove 7. The lifting assembly drives the storage net box 16 to move into the cooling groove 7, the fan 19 blows air to cool the materials, and the fried dough sticks fed in the preliminary frying enter the primary frying groove 6 to be synchronously preliminarily fried. Meanwhile, the storage net box 16 moved to the material changing groove 9 is manually fed.

[0048] After cooling, the lifting and rotating mechanism makes the material storage net box 16 enter the re-frying groove 8 through the above operation, and the material storage net box 16 in the material changing groove 9 is moved to carry out re-frying, and the material is manually loaded;

[0049] After re-frying, the lifting and rotating mechanism makes the material storage net box 16 enter the material changing groove 9, and a loading container is placed at the bottom of the material storage net box 16, the buckle lock 1604 on the lower net plate 1603 is unlocked, the lower net plate 1603 is removed, the re-fried material is poured into the container, the lower net plate 1603 is re-installed through the buckle lock 1604, then the upper net plate 1602 is removed, the material to be fried is poured, the upper net plate 1602 is re-installed on the material storage net box 16 through the buckle lock 1604, and the material changing is completed.

[0050] In the above-mentioned frying process, the fried dough sticks are continuously and uninterruptedly fried, the fried dough sticks are unloaded and reloaded during the frying of the next batch of dough sticks, so that the whole frying process does not need to be stopped, and the batch processing of fried dough sticks is suitable; meanwhile, through the design of initial frying, re-frying and cooling between initial frying and re-frying, the frying effect of fried dough sticks is improved, and the taste effect is guaranteed.
