Description

Technical Field

[0001] The present application relates to the technical field of frying equipment, and in particular to an adjustable filtering device for frying equipment for marinated products. Background Art

[0002] In the food processing industry, marinating and frying are common processes, especially when processing food ingredients coated with mixed sauces. However, during the frying process, some sauces and food residues will fall off and mix into the hot oil, causing the hot oil to coke and carbonize, seriously affecting the quality of fried foods. Since the coked materials and residual substances will continue to accumulate during the frying process, it will not only affect the taste of the food, but also accelerate the oxidation of the oil, which greatly reduces the efficiency of the frying process. Therefore, in order to improve food quality and frying efficiency and ensure the stability of the frying process, it is particularly important to develop effective impurity filtration technology.

[0003] At present, the frying equipment on the market mainly uses oil-water separation to filter impurities; it includes a connected water tank and oil tank, the oil tank is located above the water tank, due to the difference in density between oil and water, when oil and water are injected, the oil will float up and be located above the water; at the same time, a partition and a heating wire are also provided above the equipment, the heating wire heats the oil layer above, the partition is used to place food, and when in use, an opening is provided on the partition for impurities such as oil residue to pass through. An oil drain pipe is provided at the oil layer in the equipment, and a water inlet pipe is provided at the water layer. The inner diameter of the lower end of the equipment gradually decreases, and a sewage pipe is provided at the bottom, so that the water and oil in the equipment are discharged separately after use. Impurities such as oil residue generated during frying fall downward into the water, which can keep the oil layer clean. At the same time, due to the low water temperature, the oil residue can be prevented from being repeatedly fried at high temperature and carbonized.

[0004] Regarding the above-mentioned related technologies, after the oil-water separation frying equipment has been used for a certain period of time, a large amount of impurities accumulate in the water layer. Some impurities may surge upward back into the oil layer. At the same time, some smaller impurities or flocculants float in the water and are difficult to settle down, causing the water to become turbid and affecting the filtering function.

At the same time, a gap is created between the filter paper and the side wall of the scraper plate through the positioning frame, so that the part of the filter paper corresponding to the outer protrusion of the second rod can flow into the water hole along the gap between the filter paper and the scraper plate after water passes through, thereby increasing the filtering effect.

[0012] Optionally, the outer protrusion of the second rod is stepped from top to bottom, the distance between the outer protrusion located at the bottom and the side wall of the scraper plate is greater than the distance between the outer protrusion located at the top and the side wall of the scraper plate, the bending shape of the filter paper is arranged corresponding to the second rod, and the side of the filter paper that is away from the filter paper and away from the scraper plate is also stepped from top to bottom.

[0014] Optionally, a limit block is provided at the end of the third rod, and a limit groove is provided on the scraper plate for the limit block and the third rod to slide up and down, and the limit block can limit the third rod from moving in a direction away from the scraper plate; when the limit block abuts against the upper side wall of the limit groove, the inner recess of the second rod is located in the middle position of the water hole; when the second rod is subjected to a force, the limit block can slide downward.

[0015] By adopting the above technical solution, when impurities accumulate in the bent portion of the filter paper and reach a certain amount, under the action of gravity, the friction between the limit block and the side wall of the limit groove can be overcome, driving the filter paper and the positioning frame to slide downward, so that the distance between the upper side wall of the bent portion of the filter paper and the side wall of the water hole increases; during the rotation of the scraper plate, water can penetrate the upper surface of the bent portion of the filter paper and pass through the scraper plate along the distance between the filter paper and the side wall of the water hole, so that in this case, the filtration efficiency of the filter paper is further improved by moving the filter paper downward.

[0016] Optionally, a material guide hole is provided on the scraper plate, and the side walls of all the water holes at one end away from the central axis are connected to the material guide hole. A through hole is provided on the filter paper so that impurities can enter the material guide hole along the through hole, and the material guide hole extends downward to the lower surface of the scraper plate.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-5 This application is described in further detail.

[0027] The present application embodiment discloses an adjustable filtering device for frying marinated products. Figure 1 and Figure 2 The filtering device includes a body 1, with an oil storage area 101 on the top and a water storage area 102 on the bottom. Due to the difference in density between water and oil, the oil will naturally separate and float to the upper oil storage area 101; correspondingly, the upper part of the body 1 is a rectangular structure, and the lower part transitions to form an inverted truncated cone structure. A circular storage cavity 103 is also provided at the lower end of the body 1. When in use, food is placed in the upper oil storage area 101 for frying, and the oil residue after frying falls downward into the water storage area 102, and then precipitates and accumulates in the storage cavity 103.

[0028] Reference Figure 1 and Figure 2Furthermore, the body 1 is provided with an oil drain pipe 15 and a water inlet pipe 16 at the water-oil decomposition surface. The oil drain pipe 15 is located at the upper end of the water inlet pipe 16 and is located in the oil storage area 101 to facilitate the discharge of edible oil in the body 1; the water inlet pipe 16 is located at the lower end of the water inlet pipe 16 to facilitate the addition of water to the inlet when needed during use; a transparent observation window 17 is provided between the oil drain pipe 15 and the water inlet pipe 16 for observing the height position of the water layer; a sewage pipe 18 is provided at the bottom of the body 1, that is, the bottom of the storage chamber 103, for discharging impurities and waste water after use. A liquid level connecting pipe 13 is arranged on the side wall of the machine body 1. The liquid level connecting pipe 13 is connected to the oil storage area 101 above the machine body 1, and is preferably arranged at the lower position of the oil storage area 101, as far away as possible from the frying work area above. A liquid level switch 14 is arranged in the connecting pipe. When in use, the page height in the liquid level connecting pipe 13 is the same as the oil layer height in the machine body 1; when the liquid level switch 14 detects that the oil layer height drops to a certain position, an alarm is sounded to remind the operator to add edible oil into the machine body 1. Through the coordinated use of the liquid level switch 14 and the observation window 17, the height of the oil layer and the water layer in the machine body 1 can be monitored, and the height of the oil layer and the water layer in the machine body 1 can be adjusted in coordination with the water inlet pipe 16 to ensure the good operation of the frying equipment.

[0029] Reference Figure 1 and Figure 2 In this embodiment, a partition 11 and a heating wire 12 are provided in the oil storage area 101 above the machine body 1. The partition 11 is used to place the video; the partition 11 is evenly provided with openings for the oil residue produced during frying to pass through, and the heating wire 12 is provided below the partition 11 and close to the partition 11 for heating the edible oil. A temperature control probe can also be provided in the machine body 1 for detecting the oil temperature in the frying area. A foreign object guide plate 2 is arranged below the heating wire 12. The foreign object guide plate 2 is located below the heating wire 12 and in the oil layer. A plurality of foreign object guide plates 2 are arranged at intervals along the length direction of the machine body 1. Both ends of the foreign object guide plates 2 are detachably fixed to the side walls of the machine body 1. The upper surfaces of all foreign object guide plates 2 have guide slopes inclined toward the center position. After impurities such as oil residue fall on the foreign object guide plate 2, they can move downward along the guide slopes and fall from the gap between two adjacent guide slopes and enter the water layer. This achieves the effect of effectively guiding the impurities to gather toward the center. At the same time, when the impurities surge upward, the foreign object guide plate 2 can also block the impurities from entering the frying area upward.

[0030] Further optionally, rectangular plug plates are connected to both ends of the foreign object guide plate 2, and a slot for the plug plate to be inserted from top to bottom is provided on the side wall of the body 1, and a plurality of slots are arranged at intervals along the length direction of the inner wall of the body 1, so that the foreign object guide plate 2 can be positioned by inserting the plug plate into the slot; at the same time, by adjusting the position of the plug plate inserted into the slot, the distance between two adjacent foreign object guide plates 2 can also be adjusted to adapt to the production of oil residues of different sizes when frying different foods.

[0031] Reference Figure 2 and Figure 3 In this embodiment, the filtering device further comprises a central shaft 3 rotatably arranged in the machine body 1, a scraper plate 4 detachably arranged on the central shaft 3, and a driving member 5 for driving the central shaft 3 to rotate. Specifically, a positioning seat 8 is arranged in the machine, and the positioning seat 8 is preferably in a "cross" structure, and its peripheral side is fixed to the side wall of the storage cavity 103 by bolts or the like, and the upper surface of the positioning seat 8 and the boundary between the storage cavity 103 and the water storage area 102 are located on the same plane, and the central shaft 3 is rotatably arranged at the center position of the positioning seat 8 by bearings or the like; in other embodiments, in order to improve the stability of the central shaft 3 when rotating, a positioning rod can also be arranged at the upper end of the central shaft 3.

[0032] The cross section of the scraper plate 4 is a trapezoidal shape with a larger upper part and a smaller lower part. A rectangular plug-in strip is connected to the inner side of the scraper plate 4. A plug-in slot for the plug-in strip to be plugged in from top to bottom is provided on the side wall of the central axis 3. At the same time, the plug-in strip can be fixed to the central axis 3 by bolts or clamps. The side of the scraper plate 4 away from the central axis 3 is in contact with the inner side wall of the machine body 1. When the central axis 3 drives the scraper plate 4 to rotate, the scraper plate 4 can remove the impurities adhering to the side wall of the machine body 1. When the impurities accumulated between the scraper plate 4 and the side wall of the machine body 1 accumulate to a certain amount, they will move downward under the action of gravity and fall into the storage chamber 103. At the same time, the upper surface of the scraper plate 4 is at the height of the first water inlet pipe 16, and the lower surface of the scraper plate 4 is preferably located on the same plane as the upper surface of the positioning seat 8, so that the scraper plate 4 can take away the impurities falling on the surface of the positioning seat 8 during the rotation process.

[0033] Reference Figure 2 and Figure 3 In this embodiment, the scraper plate 4 is provided with water holes 41 for water to pass through, the water holes 41 extend along the length direction of the scraper plate 4, and a plurality of water holes 41 are provided on the scraper plate 4 at intervals along the axial direction of the central axis 3. A filter paper 6 is detachably provided on the side wall of the scraper plate 4. When the scraper plate 4 rotates toward the side where the filter paper 6 is located, water can pass through the filter paper 6 and the water holes 41 in sequence, and impurities and flocculants floating in the water can be adsorbed and filtered by the filter paper 6.

[0034] Reference Figure 3 and Figure 4Since the flocculated impurities generated during the frying process are relatively loose, if they are only adsorbed on the side wall of the filter paper 6, when there are more impurities adsorbed on the side wall of the filter paper 6, the impurities will fall downward under the action of gravity, and driven by the water flow, part of them will be dispersed by the water flow, and then return to the water. For this reason, in this embodiment, further, the middle part of the filter paper 6 has a bending portion protruding toward one side of the scraper plate 4, and the bending portion and the water hole 41 are arranged one by one. The cross section of the bending portion is rectangular. When water passes through the bending portion, the impurities filtered by the filter paper 6 will remain in the bending portion, and as the scraper plate 4 rotates slowly, the impurities continue to accumulate, and the flocculated impurities can also increase their density during extrusion, making it difficult for the impurities to return to the water flow, thereby improving the filtering effect on water, helping to keep the water in the water storage area 102 clean, and improving and extending the filtering effect of the entire device. In other embodiments, the scraper plate may be further configured as an arc-shaped plate. When the scraper plate 4 rotates toward the inner arc surface, the contact area between the filter paper 6 and the water can be further increased, thereby improving the filtering effect.

[0035] Reference Figure 3 and Figure 4 In an optional embodiment, the filter device further comprises a positioning frame 7 arranged on the side wall of the scraper plate 4, and the positioning frame 7 is mainly used to support and fix the filter paper 6. Specifically, the positioning frame 7 comprises a first rod 71, a second rod 72 and a third rod 73, wherein the first rod 71 is a rectangular long rod and extends along the length direction of the scraper plate 4, and the first rod 71 is respectively arranged at the upper and lower ends of the scraper plate 4; the second rod 72 is connected between the two first rods 71, and specifically, the middle part of the second rod 72 is a bent structure, which comprises an inner concave portion 721 bent and inserted into the water hole 41, and an outer convex portion 722 located on one side of the scraper plate 4, wherein the inner concave portion 721 and the outer convex portion 722 are alternately connected; the third rod 73 is fixed on the side wall of the first rod 71 facing the scraper plate 4, and the other end is connected to the positioning frame 7, and preferably, the third rod 73 is respectively arranged at both ends of each first rod 71, so that the positioning frame 7 can be connected to the scraper plate 4 more stably.

[0036] Reference Figure 3 and Figure 4, the filter paper 6 is detachably fixed to the first rod 71 and the second rod 72 on the side away from the scraper plate 4 by means of buckles or bolts, etc.; the shape of the middle bent portion of the filter paper 6 fits the second rod 72, so that the filter paper 6 can be supported by the positioning frame 7, and in order to improve the stability of the filter paper 6, multiple second rods 72 can be provided along the length direction of the first rod 71. Further, optionally, through the connection and cooperation of the third rod 73, there is a gap between the side wall of the second rod 72 and the side wall of the scraper plate 4, and there is also a gap between the inner concave portion 721 of the second rod 72 and the upper and lower side walls of the water hole 41, so that there is a gap between the filter paper 6 and the scraper plate 4. During the rotation of the scraper plate 4, when water passes through the filter paper 6 corresponding to the portion where the outer protrusion 722 of the second rod 72 is located, the filter paper 6 can play a certain filtering effect, and a small amount of water flow can flow into the water hole 41 along the gap between the filter paper 6 and the scraper plate 4; and the portion of the filter paper 6 bent and inserted into the water hole 41, in addition to the side walls arranged along the vertical direction, its upper and lower side walls can also allow water to pass through to increase the filtering effect.

[0037] Reference Figure 3 and Figure 4 In an optional embodiment, the outer protrusion 722 of the second rod 72 is stepped from top to bottom, the distance between the lower outer protrusion 722 and the side wall of the scraper plate 4 is greater than the distance between the upper outer protrusion 722 and the side wall of the scraper plate 4, the bending shape of the filter paper 6 is arranged corresponding to the second rod 72, and the side of the filter paper 6 away from the filter paper 6 and away from the scraper plate 4 is also stepped from top to bottom. Therefore, when the flocculants or smaller impurities remaining on the filter paper 6 outside the outer protrusion 722 of the second rod 72 accumulate more, they fall downward on the upper surface of the filter paper below under the action of gravity, and enter the bending part of the filter paper 6 during the rotation process for collection.

[0038] Reference Figure 3 and Figure 4In another optional embodiment, the positioning frame 7 is slidably arranged on the scraper plate 4. Specifically, a limiting block 731 is fixed at the end of the third rod 73, and the cross section of the limiting block 731 is larger than the cross section of the third rod 73. The scraper plate 4 is provided with a limiting groove 42 for the limiting block 731 and the third rod 73 to slide up and down. The cross section of the limiting groove 42 is "T" shaped. There is a certain friction force between the left and right side walls of the limiting block 731 and the side walls of the limiting groove 42. Therefore, when the limiting block 731 is located at the upper end of the limiting groove 42 and the upper surface of the limiting block 731 abuts against the upper side wall of the limiting groove 42, the entire positioning frame 7 will not slide downward under the action of friction. At this time, the inner concave portion 721 of the second rod 72 is just located in the middle position of the corresponding water hole 41. When the frying equipment is used for a long time and a large amount of impurities are adsorbed and accumulated on the bent portion of the filter paper 6, the impurities will block the side walls and the lower surface of the bent portion of the filter paper 6, thereby greatly reducing the filtering effect of the filter paper 6; through the above-mentioned arrangement, when the impurities accumulate to a certain amount, under the action of gravity, the friction between the limit block 731 and the side wall of the limit groove 42 can be overcome, driving the filter paper 6 and the positioning frame 7 to slide downward, so that the distance between the upper side wall of the bent portion of the filter paper 6 and the side wall of the water hole 41 increases; during the rotation of the scraper plate 4, water can pass through the water hole 41 along the upper surface of the bent portion of the filter paper 6, so that in this case, the filtering efficiency of the filter paper 6 is further improved by the downward movement of the filter paper 6.

[0039] Reference Figure 3 and Figure 4 In an optional embodiment, a guide hole 43 may be provided on the scraper plate 4, and the guide hole 43 extends vertically downward and extends to the lower surface of the scraper plate 4. An opening is provided on the side wall of the water hole 41 away from the central axis 3, so that all the water holes 41 are connected with the guide hole 43. At the same time, a through hole is also provided on the side of the bent portion of the filter paper 6 facing the guide hole 43, so that the impurities gathered at the bent portion of the filter paper 6 can enter the guide hole 43 under the action of centrifugal force as the scraper plate 4 rotates continuously, and fall along the guide hole 43 and enter the storage chamber 103 from below. It should be noted that in order to limit the impurities from passing through the gap between the through hole of the filter paper 6 and the side wall of the scraper plate 4, so that the impurities pass through the water hole 41, preferably, when the inner concave portion 721 of the second rod 72 is inserted into the water hole 41, its side wall abuts against the side wall of the water hole 41.

[0040] Reference Figure 3 and Figure 5In this embodiment, the driving member 5 includes a motor 51, a worm wheel 52 and a worm 53. The worm wheel 52 is coaxially fixed on the outer wall of the lower end of the central shaft 3. The worm 53 is rotatably arranged in the positioning seat 8. The worm 53 is meshed with the worm wheel 52. The motor 51 is fixed on the outer wall of the body 1. The output end of the motor 51 passes through the side wall of the body 1 and is connected to the worm 53, so that starting the motor 51 can drive the central shaft 3 to rotate. Preferably, a protective box can be set outside the worm 53 and the worm wheel 52 to seal their working environment.

[0041] Reference Figure 3 and Figure 5 In an optional embodiment, a pressing plate 9 is also slidably arranged below the positioning seat 8. The cross section of the pressing plate 9 is circular, and its outer diameter gradually increases from top to bottom, so that the upper surface of the pressing plate 9 is an arc surface, and the lower surface of the pressing plate 9 is a plane. There is a gap between the circumference of the pressing plate 9 and the inner wall of the storage cavity 103 for the oil residue to pass through. A protrusion 91 is also fixed on the upper surface of the pressing plate 9. The protrusion 91 is composed of a cylindrical rod and a semi-circular sphere located at the top of the cylindrical rod. When the scraper plate 4 rotates to the position of the protrusion 91, the lower surface of the scraper plate 4 abuts against the upper surface of the protrusion 91, driving the protrusion 91 to move downward, thereby driving the pressing plate 9 to move downward; the positioning seat 8 is also provided with an elastic member 81 that drives the pressing plate 9 to move upward.

[0042] More specifically, a guide column 82 is fixed to the lower surface of the positioning seat 8, and the guide column 82 extends vertically downward and slides through the pressure plate 9. The elastic member 81 is a spring, the upper end of the spring is fixedly connected to the positioning seat 8, and the lower end of the spring is fixedly connected to the upper surface of the pressure plate 9, and the guide column 82 passes through the spring. Preferably, two guide columns 82 are provided, and two springs are provided accordingly. The scraper plate 4 and the spring cooperate to drive the pressure plate 9 to move up and down repeatedly, so that the oil residue and impurities under the pressure plate 9 can be compacted. This design improves the collection efficiency of the oil residue and impurities and reduces the waste of oil quality; at the same time, by compacting the impurities, it can also reduce the possibility of impurities moving upward, thereby increasing the cleanliness of the upper water.

[0043] The implementation principle of the adjustable filtering device of the marinated food frying equipment of the embodiment of the present application is as follows: when in use, water and oil are injected into the machine body 1. When frying, the food is placed on the partition 11 for frying, and the oil residue produced by frying falls downward into the water storage area 102, thereby separating the impurities; the scraper plate 4 in the lower water storage area 102 rotates, and the filter paper 6 set on the scraper plate can filter and absorb the impurities in the water, thereby continuously purifying the water and improving the continuous filtering effect of the filtering device. During the rotation of the scraper plate 4, it can drive the tip of the pressing plate 9 to press down, so as to compact the oil residue and impurities located below the pressing plate 9.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
