Abstract
Description
Technical Field
[0001] This utility model relates to the field of fried food processing technology, and in particular to a vortex centrifugal quick-freezing gradient degreasing device for fried foods. Background Technology
[0002] Fried foods are a popular convenience food, and the oil removal process during processing directly affects the taste and quality of the product. With the development of modern food industry, frozen fried foods have developed rapidly due to their convenient storage and consumption. These products must undergo thorough oil removal before freezing to prevent the oil from solidifying at low temperatures, which would lead to a decline in product quality.
[0003] Existing technologies for degreasing frozen and fried foods suffer from two main technical defects: first, the airflow generated during high-speed rotation accelerates the temperature drop of the food, leading to increased oil viscosity and affecting degreasing efficiency; second, the commonly used single-stage filtration system results in incomplete oil-sludge separation, leaving the recovered oil with a significant amount of solid impurities, which not only reduces oil quality but also increases subsequent refining costs. These problems directly impact production efficiency and product quality and urgently require improvement. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vortex centrifugal gradient degreasing device for quick-frozen fried foods.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vortex centrifugal gradient degreasing device for quick-frozen fried foods includes a support base. One side of the support base has an insertion groove into which a processing frame is inserted. A filter frame is installed at the bottom of the processing frame. The top and bottom of the support base both have through grooves communicating with the insertion groove. A processing bucket communicating with the through grooves is fixedly connected to the top of the support base. A temperature control mechanism is fitted around the outer wall of the processing bucket. A top cover is provided on the top of the processing bucket. A rotating rod rotatably connected to the top cover is located inside the processing bucket. A stepper motor driving the rotating rod is installed on the top of the top cover. A strainer frame is fixedly connected to the bottom of the rotating rod. Telescopic mechanisms driving the top cover to move are provided on both sides of the top of the support base. A conical frame is fixedly connected to the bottom of the support base at the through groove, and an oil outlet valve is connected to the bottom of the conical frame.
[0006] As a further improvement of this utility model, the constant temperature mechanism includes a water pipe wound inside a cylindrical frame, an inlet connector connected to one end of the water pipe and a outlet connector connected to the other end of the water pipe and fixedly connected to the upper side of the cylindrical frame.
[0007] As a further improvement of this utility model, the telescopic mechanism includes a hydraulic cylinder fixedly connected to the top of the support base, and a push block is fixedly connected to the telescopic end of the hydraulic cylinder, and the push block is fixedly connected to one side of the top cover.
[0008] As a further improvement of this utility model, a U-shaped frame is fixedly connected to one side of the support base, and an L-shaped pin that can be vertically inserted and removed is provided on the U-shaped frame. When the L-shaped pin is inserted, it can prevent the processing frame from disengaging from the insertion slot.
[0009] As a further improvement of this utility model, a pull-out handle is fixedly connected to one side of the processing frame.
[0010] As a further improvement of this utility model, support columns are fixedly connected to the four corners of the bottom of the support base.
[0011] The beneficial effects of this utility model are: By setting up a pull-out processing frame and filter frame, combined with a U-shaped frame and L-shaped pin locking structure, the device can be quickly disassembled and maintained; the dual-stage filtration system of the strainer frame and filter frame significantly improves the oil-liquid separation effect; the constant temperature mechanism maintains the optimal working temperature through circulating water to ensure oil removal efficiency; the combination of the hydraulic cylinder-driven top cover lifting mechanism and the stepper motor-controlled gradient centrifugal system makes the entire oil removal process highly automated and easy to operate, ensuring both oil removal effect and easy oil residue cleaning and grease recovery, making it particularly suitable for the industrial production needs of quick-frozen fried foods.
[0012] This invention achieves efficient and automated oil removal, and features simple operation and convenient maintenance, significantly improving the oil removal efficiency and quality of quick-frozen fried foods. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Figures 1-4 A vortex centrifugal gradient degreasing device for quick-frozen fried foods includes a support base 1. Support columns 2 are fixedly connected to the four corners of the bottom of the support base 1 to maintain the stability of the device during operation. An insertion slot 8 is provided on one side of the support base 1, into which a processing frame 9 is inserted and can be pulled and moved along the insertion direction. A pull handle 14 is fixedly connected to one side of the processing frame 9 for easy application of force by the operator. A U-shaped frame 12 is fixedly connected to one side of the support base 1 to provide an installation foundation. The upper part is provided with an L-shaped pin 13 that can be vertically inserted and removed, which is used to lock the insertion position of the processing frame 9. When the L-shaped pin 13 is inserted, it can prevent the processing frame 9 from disengaging from the insertion slot 8. A filter screen frame 19 is installed at the inner bottom of the processing frame 9 to filter the de-oiled grease and separate the residual oil residue. The top and bottom of the support base 1 are provided with through grooves 22 that communicate with the insertion slot 8 to form an oil flow channel. The top of the support base 1 is fixedly connected to a processing bucket 16 that communicates with the through groove 22, forming a working chamber for centrifugal de-oiling.
[0017] The outer wall of the treatment tank 16 is fitted with a thermostatic mechanism to maintain the optimal working temperature of the oil. The thermostatic mechanism includes a water pipe 15 wound inside the cylindrical frame 3, which achieves heat exchange through water circulation. A water inlet connector 20 connected to one end of the water pipe 15 is fixedly connected to the upper side of the cylindrical frame 3 for introducing the thermostatic medium. A water outlet connector 21 connected to the other end of the water pipe 15 is fixedly connected to the lower side of the cylindrical frame 3 to complete the medium circulation loop.
[0018] The top of the processing tank 16 is provided with a top cover 6 to seal the working chamber. Inside the processing tank 16 is a rotating rod 17 rotatably connected to the top cover 6. A stepper motor 7 is installed on the top of the top cover 6 to drive the rotating rod 17 to rotate, providing the rotational power required for centrifugal degreasing, and controlling the gradient speed through program settings. A strainer frame 18 is fixedly connected to the bottom of the rotating rod 17 to carry the food to be degreased and achieve oil-liquid separation. Both sides of the top of the support base 1 are provided with telescopic mechanisms to drive the top cover 6 to move, realizing the opening and closing control of the working chamber. The telescopic mechanism includes a hydraulic cylinder 4 fixedly connected to the top of the support base 1 to provide linear driving force. A push block 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4 to transmit hydraulic motion to the top cover 6. The push block 5 is fixedly connected to one side of the top cover 6 to ensure the synchronous lifting and lowering movement of the top cover 6. A conical frame 10 is fixedly connected to the bottom of the support base 1 at the through groove 22 to collect the separated oil. An oil outlet valve 11 is connected to the bottom of the conical frame 10 to control the timing and flow of oil discharge.
[0019] In use, the top cover 6 is first driven to rise by the hydraulic cylinder 4, which in turn moves the rotating rod 17 and the strainer frame 18 upwards. After the food to be degreased is placed in the strainer frame 18, the top cover 6 is closed, and the L-shaped pin 13 on the U-shaped frame 12 locks the insertion position of the processing frame 9. When the stepper motor 7 is started to accelerate the centrifugal degreasing process, the oil passes through the strainer frame 18 and the filter frame 19 installed at the bottom of the processing frame 9 for secondary filtration. After degreasing is completed, the L-shaped pin 13 is pulled out first, and then the pull handle 14 is held to pull out the processing frame 9 along the insertion groove 8 for cleaning. The separated, cleaner oil flows into the conical frame 10 through the channel 22 and is discharged through the oil outlet valve 11. After collection, it is recycled and reused. The constant temperature mechanism controls the temperature through the water inlet connector 20 and the water outlet connector 21 to ensure that the food does not cool down due to rotation, which would affect the degreasing effect. After degreasing is completed, the top cover 6 is raised to remove the food.
[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
