Abstract
Description
Technical Field
[0001] The utility model relates to frying equipment, in particular to a vacuum frying tank. Background Art
[0002] In food processing technology, people often use edible oil to fry various foods at high temperatures. Fried foods are fragrant and crispy and are very popular among consumers. Vacuum low-temperature frying technology not only preserves the pure natural color, nutrition and flavor of fresh fruits and vegetables, but also has the characteristics of low fat, low calories and high fiber. The oil content is significantly lower than that of traditional fried foods, there is no greasy feeling, and it does not produce carcinogens such as 3-4 benzopyrene and acrylamide. Therefore, it is widely used in the field of fried vegetables.
[0003] In the existing frying process, the heated cooking oil needs to be passed into a closed tank body, so as to fry the vegetables already placed in the tank body. After frying, the cooking oil is discharged and the vegetables are taken out after cooling, and the vegetables are placed in a centrifuge for centrifugation to remove the residual oil therein, which can not only recover the oil but also facilitate the subsequent processing of the vegetables. However, this is likely to lead to two problems. First, the fried vegetables need to be manually transported to the centrifuge for further centrifugation, which requires a separate step. During this period, it is not only easy to expose the vegetables to the air before they are dried, affecting the taste, but also time-consuming and laborious. Second, the oil splashes everywhere in the centrifuge due to centrifugation, which requires a separate recovery process and special personnel to clean it, which invisibly increases the cost. Utility Model Content
[0004] The utility model provides a vacuum frying tank, which can not only directly perform the oil draining process in the whole frying equipment, but also the oil is always concentrated in a fixed area during the draining process without splashing everywhere, and the collected oil is directly discharged, which reduces the labor intensity of the workers and also reduces the threshold of the professional skills of the operating workers, so that even new workers can use it skillfully.
[0005] The utility model is achieved in this way:
[0006] A vacuum frying tank comprises a frying tank body, a containing frame is arranged in the frying tank body, the frying tank body comprises a hollow cavity, an oil return pipe is arranged at the bottom of one side of the hollow cavity, an oil inlet pipe is arranged in the middle of the other side of the hollow cavity, and further comprises:
[0007] A centrifugal de-oiling structure, wherein the centrifugal de-oiling structure comprises a rotating motor arranged at the top center of the frying tank body, wherein the rotating motor extends to the interior of the frying tank body through a rotating shaft and is connected to the top of the containing frame, and after the oil return pipe is opened to drain the oil in the frying tank body, the rotating motor drives the containing frame to rotate and de-oil via the rotating shaft.
[0008] As a further improvement, the accommodating frame includes a fixed frame connected to the rotating shaft, and a material placing frame is movably connected to the inner side of the fixed frame, and the material placing frame is connected to the fixed frame via a locking structure.
[0009] As a further improvement, a push rod motor arranged on the outside of the frying tank is connected below the rotating shaft, the output end of the push rod motor extends to the inside of the frying tank, and the output end of the push rod motor is locked to the containing frame.
[0010] As a further improvement, it also includes an oil guiding and collecting structure, wherein a plurality of uniform small holes are opened on the outer side of the containing frame, and the oil is fried through the small holes in the containing frame. The oil guiding and collecting structure includes a guiding rib fixedly connected to the outer side of the containing frame, and an outer partition frame is fixedly connected to the side of the guiding rib away from the containing frame, and an oil hopper is provided at the bottom of the outer partition frame extending toward one side of the containing frame. When the containing frame rotates centrifugally, the oil seeps out through the small holes and flows into the outer partition frame and is concentrated in the oil hopper.
[0011] As a further improvement, the guide ribs are arc-shaped bars, and the oil centrifuged through the small holes slides down along the arc-shaped bars to the outer partition frame.
[0012] As a further improvement, the lower flow pipe includes a feed introduction cavity connected to the outer partition frame, the bottom of the feed introduction cavity is connected to a conducting pipe, and an electromagnetic valve is arranged on the inner side of the conducting pipe.
[0013] The beneficial effects of the utility model are:
[0014] In the existing vacuum frying equipment, after the fried vegetables are drained from the tank, they need to be transported to an external space for centrifugal de-oiling, so that the surface of the vegetables is no longer attached to oil and becomes crisp and delicious. However, this requires special personnel to transport and put them into the centrifuge. At the same time, the centrifuge also requires daily maintenance, which increases the company's labor costs and equipment costs. In addition, vegetables that are not completely drained may be directly exposed to the air and may contain water on their surface, affecting their taste. Therefore, the utility model proposes a centrifugal de-oiling structure, that is, de-oiling is directly achieved in the frying tank, and before frying, the vegetables are drained through the oil inlet pipe. The cooking oil heated by the heat exchanger is passed into the hollow cavity to fry the vegetables. After the frying is completed, the oil is discharged through the oil return pipe. At this time, the height of the oil continues to decrease, which is actually the process of the entire containing frame draining the oil. After the oil drops below the height of the containing frame, the rotating shaft is driven by the rotating motor to make the containing frame connected to the rotating shaft start to rotate, so that the oil droplets in the vegetables are thrown out, and the oil is dehydrated directly in a vacuum environment, thereby ensuring the taste of the fried vegetables. There is no need to go through multiple processes, and all the steps are completed directly in the frying tank. Even new employees can operate it. BRIEF DESCRIPTION OF THE DRAWINGS

The centrifugal de-oiling structure includes a rotating motor 51 arranged at the top center of the frying tank body 10, and the rotating motor 51 extends to the inside of the frying tank body 10 through a rotating shaft 52 and is connected to the top of the containing frame 11. After the oil return pipe 13 is opened to drain the oil in the frying tank body 10, the rotating motor 51 is connected to the top of the containing frame 11 through the rotating shaft 52. The receiving frame 11 is driven to rotate and de-oil; an oil guiding and collecting structure is provided, wherein a plurality of uniform small holes are provided on the outer side of the receiving frame 11, and the oil is fried through the small holes to fry the vegetables in the receiving frame 11. The oil guiding and collecting structure comprises a guiding rib 61 fixedly connected to the outer side of the receiving frame 11, and an outer partition frame 62 is fixedly connected to the side of the guiding rib 61 away from the receiving frame 11, and an oil hopper 63 is provided at the bottom of the outer partition frame 62 extending toward one side of the receiving frame 11, and the oil in the receiving frame 11 seeps out through the small holes and flows into the outer partition frame 62 when the receiving frame 11 is centrifugally rotated. The oil is concentrated in the oil hopper 63; an oil mid-drain structure, the lower part of the oil hopper 63 is fixedly connected with a lower circulation pipe 64, the oil mid-drain structure includes a lower recessed groove 71 communicated with the oil return pipe 13, a material blocking member 72 is arranged in the lower recessed groove 71, the material blocking member 72 is lifted and installed in the lower recessed groove 71, when the rotating motor 51 decelerates to a preset speed, the material blocking member 72 rises and blocks the lower circulation pipe 64, the lower circulation pipe 64 opens and pours the oil in the oil hopper 63 into the lower recessed groove 71.
[0029] In this embodiment, the fried vegetables are carrots, mushrooms, potatoes and other vegetables that are not easy to become loose, and they are not easy to be fried during the frying stage, thereby reducing the burden on the filtering end.
[0030] In the cooperation between the frying tank body 10 and the rotating motor 51, a polytetrafluoroethylene pad needs to be set at the installation port of the frying tank body 10 to seal the cooperation position to better maintain the vacuum frying state and avoid possible pollution to the internal environment of the frying tank body 10 by the rotating motor 51.
[0031] In the existing vacuum frying equipment, after the fried vegetables are drained from the tank, they need to be transported to an external space for centrifugal de-oiling, so that the surface of the vegetables is no longer attached to oil and becomes crisp and delicious. However, this requires special personnel to transport and put them into the centrifuge. At the same time, the centrifuge also requires daily maintenance, which increases the company's labor and equipment costs. In addition, vegetables that are not completely drained may be directly exposed to the air and may contain water on their surface, affecting their taste. Therefore, this embodiment proposes a centrifugal de-oiling structure, that is, de-oiling is directly achieved in the frying tank 10. Before frying, the vegetables heated by the heat exchanger 20 are heated to a temperature of 100°C by the oil inlet pipe 14. The edible oil is passed into the hollow cavity 12 to fry the vegetables, and after the frying is completed, the oil is discharged through the oil return pipe 13. At this time, the level of the oil continues to decrease, which is actually the process of the entire containing frame 11 draining the oil. After the oil drops below the level of the containing frame 11, the rotating shaft 52 is driven by the rotating motor 51, so that the containing frame 11 connected to the rotating shaft 52 starts to rotate, so that the oil droplets in the vegetables are thrown out, and deoiling is directly formed in a vacuum environment, thereby ensuring the taste of the fried vegetables. There is no need to perform multiple processes, and all the steps are completed directly in the frying tank 10. Even new employees can operate it.
[0032] Although the centrifugal deoiling step is completed directly in the frying tank body 10, as the oil is completely discharged from the frying tank body 10, the oil splashed out by the centrifugation will scatter everywhere, and due to the small amount, it is impossible to collect and recover it, resulting in the frying tank body 10 needing to be cleaned separately after centrifugation. Therefore, the utility model provides an oil guide and collection structure on the basis of the centrifugal deoiling structure. In the normal frying state and the oil draining state, the oil can freely enter and exit the accommodating frame 11 through the small holes at the bottom or top of the accommodating frame 11, thereby achieving the purpose of frying and oil draining. During centrifugal shaking, the oil that is thrown out will be thrown to the outer partition frame 62 to be restricted by the outer partition frame 62, and all of it will be concentrated in the oil hopper 63 along the guide ribs 61 for unified treatment, thereby preventing the oil from splashing everywhere and being difficult to collect, and no separate cleaning step is required.
[0033] Specifically, the guide rib 61 is an arc-shaped bar, and the oil centrifuged through the small hole slides down along the arc-shaped bar to the outer partition frame 62. Compared with directly falling slowly through the inner side of the outer partition frame 62, the oil collection effect is better.
[0034] The oil hopper 63 does not cover the entire bottom of the containing frame 11, otherwise it will easily affect the oil flow effect during the frying stage. Therefore, the oil hopper 63 in this embodiment is actually a square frame with a hollow middle portion so that the middle portion can make room for the oil, and the frame portion, being located at the periphery, can just receive the oil droplets blocked by the outer partition frame 62, thereby achieving the effect of gathering the oil droplets without hindering frying.
[0035] In order to facilitate the installation and fixation of the oil bucket 63, the cross-section of the oil bucket 63 is an L-shaped structure. One end of the long axis of the oil bucket 63 is connected to the bottom of the outer partition frame 62, and one end of the short axis of the oil bucket 63 is fixedly connected to the bottom of the containing frame 11, so that the normal use of the containing frame 11 can be not hindered while achieving the oil collection effect.
[0036] If the collected oil is discharged in a disorderly manner, the entire collection process will be meaningless. Therefore, in this embodiment, an oil mid-drain structure is added on the basis of the oil guide collection structure. Through the material blocking member 72 cooperating with the lower flow pipe 64, the material blocking member 72 is raised when the speed of the rotating motor 51 decreases, and the lower flow pipe 64 is blocked by the material blocking member 72 when the rotating motor 51 stops. As a result, the oil flowing down through the oil hopper 63 and the lower flow pipe 64 will be caught by the material blocking member 72 and directly guided to the lower recessed groove 71, thereby realizing the orderly discharge of the oil. Even in the centrifugal deoiling stage, the subsequent cleaning time can be reduced, and the efficiency of oil recovery is also improved.
[0037] The lower flow pipe 64 cooperates with the material blocking member 72. Specifically, the lower flow pipe 64 includes a material introduction chamber 641 connected to the outer partition frame 62. The bottom of the material introduction chamber 641 is connected to a conducting pipe 642. An electromagnetic valve is arranged on the inner side of the conducting pipe 642. By turning on and off the internal electromagnetic valve, oil can be discharged in time when the material blocking member 72 is in place.
[0038] In order to prevent the blocking member 72 from obstructing the normal rotation of the oil guide and collection structure during the de-oiling stage, the blocking member 72 in this embodiment is set to be in a liftable state, so that the blocking tube 722 can be raised to cooperate with the conducting tube 642 when needed, and lowered to not interfere with the entire de-oiling process when not needed.
[0039] Specifically, the material blocking member 72 includes a lifting mechanism 721 arranged on the outside of the frying tank 10, and a material blocking tube 722 is connected to the top of the lifting mechanism 721. The lifting mechanism 721 is electrically connected to the rotating motor 51, so that the movement of the lifting mechanism 721 can follow the movement of the rotating motor 51 and will not extend at an inappropriate time.
[0040] In order to make the material blocking tube 722 better cooperate with the guiding tube 642, a notch that cooperates with the guiding tube 642 is opened on the side of the material blocking tube 722. When the guiding tube 642 is rotated to the position of the material blocking tube 722, it is stuck by the notch. A leakage groove is opened on the side of the material blocking tube 722 facing the lower recessed groove 71. After the guiding tube 642 is blocked by the material blocking tube 722, the oil leaked from the guiding tube 642 into the material blocking tube 722 is input into the lower recessed groove 71 through the leakage groove, forming a seamless connection while making the oil leakage point more accurate.
[0041] In the process of oil leakage, in order to prevent the oil from overflowing, the overflowed oil needs to be guided. Therefore, in this embodiment, the height of the lower recessed groove 71 is lower than the inner bottom surface of the frying tank body 10, and the lower recessed groove 71 is inclined toward one side of the oil return pipe 13, so that the oil can flow out directly along the inclined lower recessed groove 71, thereby achieving the effect of fast and accurate oil guiding.
[0042] During the entire frying process, the accommodating frame 11 needs to be able to be pushed in and out so that the fried products can be placed in and taken out. Therefore, the accommodating frame 11 includes a fixed frame 111 connected to the rotating shaft 52. The inner side of the fixed frame 111 is movably connected to a material placing frame 112. The material placing frame 112 is connected to the fixed frame 111 through a locking structure, so that the material placing frame 112 can be opened and closed. The locking structure can be an ordinary connecting locking structure as long as it can withstand high temperatures. It is not specifically expanded in this embodiment.
[0043] Embodiment 2
[0044] The above method is to drain the oil first and then drain it. However, in fact, the oil can be drained without draining the oil. In another embodiment of the utility model, a solution for draining the oil in the frying tank 10 is provided as follows:
[0045] A push rod motor arranged on the outside of the frying tank body 10 is connected to the lower part of the rotating shaft 52, and the output end of the push rod motor extends to the inner side of the frying tank body 10. The output end of the push rod motor is locked to the containing frame 11, that is, the push rod motor is arranged at the lower end of the rotating shaft 52, and the containing frame 11 can be directly raised and lowered by the push rod motor, so that the whole containing frame 11 can be raised when the oil needs to be drained, and the whole containing frame 11 can be immersed in the oil in the frying state. Since the scheme is relatively simple, no drawings are provided.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
