Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and specifically relates to an oil residue cleaning device for a frying pan. Background Art

[0002] A frying machine is a common food processing device widely used in the food processing industry. During the use of a frying machine, as the number of times the oil is used increases, carcinogenic substances in the oil such as malondialdehyde, benzo[a]pyrene, and heterocyclic amine compounds will increase significantly, endangering human health. Especially, the used oil contains a large amount of oil residues, which exacerbates the deterioration of the oil. Therefore, the oil needs to be replaced and purified regularly. To replace the used oil, the machine needs to be shut down, and then all the oil is drained. The residues are filtered through a filtering device, and then the oil is optimized.

[0003] There is a large amount of bran on the surface of fried foods, which is likely to fall off during frying. Therefore, during each frying process, a large amount of residue will fall into the frying pan. The bran residues are small and are easily turned into charred particles in high-temperature oil. After low-temperature fresh food is put into the frying pan, the black charred residues are very likely to adhere to the food, which will affect the taste and appearance of the food. The cycle for cleaning oil residues is much shorter than the cycle for changing oil. Currently, the method of changing oil is used to clean oil residues, and only by pumping out all the oil for filtration. However, when pouring the oil back into the frying pan, although the oil residues can be completely cleaned, frequent shutdowns affect production capacity and also consume edible oil, resulting in material waste, and manual fishing for oil residues in the frying pan is inefficient. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is the problem that the accumulation of oil residues in the existing frying pan is large and not easy to clean.

[0005] To solve the above problems, the utility model adopts the following technical solutions:

[0006] To achieve the above purpose, the main technical means adopted in this technical solution are as follows:

[0007] An oil residue cleaning device for a frying pan includes a stirring shaft, with the upper end connected to a motor and the lower end connected to a stirring paddle; a sleeve shaft, sleeved outside the stirring shaft, with the lower end rotatably connected to the stirring shaft and the upper end connected to the stirring shaft through a transmission component; a net bag, with the bag mouth connected to a support ring, and the support ring fixed to the side of the sleeve shaft; a transmission component, linking the sleeve shaft and the stirring shaft and causing them to rotate in opposite directions.

[0008] The utility model adopting the above structure, compared with the prior art, has the following beneficial effects:

[0009] 1) This solution uses stirring to make the oil dregs at the bottom of the pot float, and then uses a net bag to fish and filter the oil dregs to achieve cleaning the dregs in the frying machine pot; 2) In this solution, the net bag moves in the reverse direction of the liquid flow, and uses the liquid flow pressure to prevent the oil dregs from floating out of the net bag, and the oil dregs are fished out cleanly; 3) For this solution to achieve cleaning the dregs in the pot without stopping the machine, it prolongs the service life of the edible oil. The utility model can effectively reduce the shutdown frequency, can clean the oil dregs at any time and immediately, avoid the pollution of fried foods by black and burnt oil dregs, and reduce the environmental pollution.

[0010] As a preference, a further technical solution of the above structure is:

[0011] The transmission assembly includes a mounting frame, a main gear, an internal gear ring and a transmission wheel. The mounting frame is composed of a top plate and an end cover. The top plate is provided with a central hole, and the central hole is sleeved on the upper end of the stirring shaft and is rotationally matched with the stirring shaft. The motor is fixedly installed on the upper side of the top plate; the end cover is fixedly connected to the lower side of the top plate, and the end cover is sleeved on the upper end of the sleeve shaft and is rotationally matched with it; the main gear is fixed on the outer wall of the stirring shaft, the internal gear ring is fixed on the inner wall of the sleeve shaft, the transmission wheel is arranged between the stirring shaft and the sleeve shaft, one side of which meshes with the main gear, and the other side meshes with the internal gear ring. The transmission wheel is installed at the lower end of the connecting rod, and the upper end of the connecting rod is fixed to the top plate.

[0012] The beneficial effect obtained from the above features: This solution drives the stirring shaft and the sleeve shaft through gear transmission, with high transmission efficiency and good stability, and the gear also has the function of supporting the distance between the stirring shaft and the sleeve shaft.

[0013] Optionally, the transmission wheel includes a first pinion gear, and the first pinion gear meshes with both the main gear and the internal gear.

[0014] The beneficial effect obtained from the above features: This example simply realizes the movement of the sleeve shaft in the opposite direction to the stirring shaft.

[0015] Optionally, the transmission wheel includes a first pinion gear and a second pinion gear fixed coaxially, and the number of teeth of the second pinion gear is less than that of the first pinion gear.

[0016] The beneficial effect obtained from the above features: This example reduces the rotation speed of the sleeve shaft through the second pinion gear, avoids the agitation of the liquid flow by the net bag when the net bag moves, which offsets the swirl generated by the stirring paddle, and keeps the liquid flow pressing on the net bag.

[0017] The stirring paddle is composed of a paddle core and three paddle blades. The paddle core is fixedly installed at the lower end of the stirring shaft. The paddle blades are arc-shaped plates. The inner ends of the paddle blades are fixedly connected to the paddle core and their long sides are parallel to the axis of the paddle core. The lower side of the outer end of the paddle blade inclines towards the front side of the rotation.

[0018] The beneficial effect obtained from the above features: With the structure of this stirring paddle, the arc-shaped plates make the oil and oil dregs on the outer periphery move towards the middle, and the downward inclination of the lower side of the paddle blades makes the oil and oil dregs in the lower layer move upwards, thus forming a spiral upward liquid flow, enabling the oil dregs to fully enter the range of the net bag.

[0019] The net bag is made of soft filter cloth, and the net bags are arranged staggered along the sleeve shaft, and the plane of the support ring is parallel to the axial direction of the sleeve shaft.

[0020] The beneficial effects obtained from the above features: The structure of the support ring in this example obtains a larger fishing plane, which improves the speed of the oil residue being captured by the net bag; the use of a soft filter cloth makes the net bag droop naturally when the rotation stops to avoid the oil residue from falling out.

Sealing sheets are arranged on the upper side and the lower side of the central hole; the sealing sheets prevent oil from leaking into the shaft. Description of the Drawings

[0030] The present invention will be further described below in conjunction with the embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0031] See Figures 1 to 7 , a device for cleaning oil residue in a deep fryer provided by the present invention includes:

[0032] The stirring shaft 2 is connected to the motor at the upper end and the stirring paddle 1 at the lower end;

[0033] The sleeve shaft 3 is sleeved outside the stirring shaft 2, rotatably connected to the stirring shaft 2 at the lower end, and connected to the stirring shaft 2 through a transmission assembly 4 at the upper end;

[0034] The mesh bag 5 has its bag mouth connected to a support ring, and the support ring is fixed to the side of the sleeve shaft 3;

[0035] The transmission assembly 4 interlocks the sleeve shaft 3 and the stirring shaft 2 and makes them rotate in opposite directions.

[0036] This solution is designed to use the stirring paddle 1 to make the oil residue roll and float. The mesh bag 5 is designed to rotate in the opposite direction to the stirring paddle 1, so that the mesh bag 5 moves countercurrently to filter the oil residue in the edible oil. The inside of the mesh bag 5 is under the pressure of the liquid flow, keeping the oil residue in the mesh bag 5. After the device rises out of the oil pan 7, the oil residue is separated from the edible oil.

[0037] In this solution, the mesh bag 5 is made of a soft filter cloth. The mesh bags 5 are arranged staggeredly along the sleeve shaft 3, and the plane of the support ring is parallel to the axial direction of the sleeve shaft 3. The staggered arrangement of the mesh bags 5 and the perpendicular setting of the support rings can obtain a larger fishing cross-section and improve the speed at which the oil residue is captured by the mesh bag 5; using a filter cloth made of a soft material allows the mesh bag 5 to hang down naturally when the rotation stops, preventing the oil residue from falling out.

[0038] As an option, see Figures 2 to 4 , the transmission assembly 4 includes a mounting frame 46, a main gear 41, an internal gear ring 44 and a transmission wheel. The mounting frame 46 is composed of a top plate and an end cover. The top plate is provided with a central hole, and the central hole is sleeved on the upper end of the stirring shaft 2 and is rotationally matched with the stirring shaft 2. The motor is fixedly installed on the upper side of the top plate; the end cover is fixedly connected to the lower side of the top plate, and the end cover is sleeved on the upper end of the sleeve shaft 3 and is rotationally matched with it; the main gear 41 is fixed to the outer wall of the stirring shaft 2, the internal gear ring 44 is fixed to the inner wall of the sleeve shaft 3, the transmission wheel is arranged between the stirring shaft 2 and the sleeve shaft 3, meshes with the main gear 41 on one side and meshes with the internal gear ring 44 on the other side. The transmission wheel is installed at the lower end of a connecting rod 45, and the upper end of the connecting rod 45 is fixed to the top plate. The gear transmission has good stability, and also has a supporting function, and the gear has the function of supporting the distance between the stirring shaft 2 and the sleeve shaft 3.

[0039] In the first embodiment, the transmission wheel is only a first pinion 42, and the first pinion 42 meshes with both the main gear 41 and the internal gear. The first pinion 42 is fixed in position by the connecting rod 45, transmits the rotation of the stirring shaft 2 to the sleeve shaft 3, and the mesh bag 5 rotates in the opposite direction to the liquid flow, pressing the oil residue entering the mesh bag 5 inside by the liquid flow pressure.

[0040] The stirring paddle 1 rotates forward to generate a spiral liquid flow of the cooking oil, while the wire mesh bag 5 rotates in the opposite direction, also generating a stirring effect on the oil. To avoid the interference of the two components on the liquid flow, a structure for reducing the speed of the wire mesh bag 5 is designed in this solution. In Embodiment 2, the transmission wheel includes a first small gear 42 and a second small gear 43 fixed coaxially. The number of teeth of the second small gear 43 is less than that of the first small gear 42. The motor drives the stirring shaft 2 to rotate the main gear 41, and the main gear 41 drives the first small gear 42 to rotate, thereby rotating the second small gear 43 fixed coaxially with the first small gear 42. Since the number of teeth of the second small gear 43 is small, when the first small gear 42 rotates one week, the second small gear 43 only pulls the internal gear ring 44 several times. Compared with Embodiment 1, Embodiment 2 can reduce the rotation speed of the sleeve shaft 3.

[0041] In this solution, the diameter difference between the main gear 41 and the internal gear ring 44 makes the rotation speed of the internal gear ring 44 slower than that of the main gear 41 during transmission. The stirring shaft 2 is used to drive the stirring paddle 1 and needs to have greater strength. A large internal gear ring 44 will increase the weight of the device. Therefore, the main gear 41 should not be too small and the internal gear should not be too large, otherwise the speed difference cannot reach the expected effect. Therefore, the above Embodiment 2 is a better choice. Optionally, the number of teeth of the second small gear 43 is 1 - 4. By setting the number of teeth of the second small gear 43, the purpose of adjusting the rotation speed of the wire mesh bag 5 can be achieved.

[0042] As an option, refer to Figure 6 , the stirring paddle 1 is composed of a paddle core 102 and three paddle blades 101. The paddle core 102 is fixedly installed at the lower end of the stirring shaft 2. The paddle blades 101 are arc-shaped plates. The inner ends of the paddle blades 101 are fixedly connected to the paddle core 102 and their long sides are parallel to the axis of the paddle core 102. The lower side of the outer end of the paddle blade 101 is inclined towards the front side of the rotation; with this structure of the stirring paddle 1, the arc-shaped plates make the oil and oil residues on the outer periphery move towards the middle, and the downward inclination of the lower side of the paddle blade 101 makes the oil and oil residues in the lower layer move upward, thereby forming a spiral upward liquid flow and enabling the oil residues to fully enter the range of the wire mesh bag 5.

[0043] Optionally, refer to Figure 5 , a baffle 31 is fixedly connected to the lower end of the sleeve shaft 3. The baffle 31 is provided with a central hole, and the central hole is rotationally matched with the stirring shaft 2. Sealing sheets 6 are arranged on the upper side and the lower side of the central hole to prevent oil from leaking into the shaft at the bottom.

[0044] Optionally, refer to Figure 7 , the wire mesh bags 5 are arranged staggeredly along the sleeve shaft 3, and the wire mesh bags 5 cover the cross-section of the spiral liquid flow as large as possible. A handle 9 or a fixed clamping part 8 is arranged on the mounting frame 46. For a smaller oil pan 7, the mounting frame 46 can be clamped on the upper opening of the oil pan 7 to fix the position for stirring and removing residues. For a larger extended fuel tank, the handle 9 can be held and the residues can be removed by pushing along the fuel tank.

[0045] The above are only the preferred and feasible embodiments of the present utility model, and thus do not limit the scope of rights of the present utility model. Any equivalent changes made by using the content of the specification and drawings of the present utility model are included within the scope of rights of the present utility model.
