Description
Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to a fried broad bean oil draining and cooling device. Background Art
[0002] Broad beans are a small grain and have very important value in life. They can be used as traditional staple food, as well as modern green food and nutritional health food. There are many ways to cook broad beans. For example, fried broad beans are a very popular snack and have always been loved by consumers. Fried broad beans use broad beans as the main raw material and are made through peeling, soaking, gelatinization, frying, mixing and other processing techniques.
[0003] In the production process of fried broad beans, the fried broad beans need to be drained and cooled before entering the next production process. Traditional oil draining and cooling devices are usually air-blown cooling and oil draining. The fried broad beans are often placed on a filter conveyor belt, and the vegetable oil is collected by dripping down due to its own weight. At the same time, the wind is used to blow the oil on the surface of the broad beans away from the broad beans and cool them down at the same time. However, this oil draining method with a conveyor belt has some problems, such as the conveyor belt is too long and occupies a large area. In order to prevent the wind from blowing the oil and broad beans to the ground, partitions are installed on both sides of the conveyor belt to prevent splashing. However, this also causes some problems, such as debris and dust are easily trapped on the partition, and the oil blown onto the partition is contaminated, affecting recycling and reuse. If a cover is added, the heat cannot be dissipated quickly, and for the sake of production efficiency, the broad beans will be stacked on the conveyor belt. Although this is conducive to draining a large amount of oil, it will cause some broad beans at the bottom to be over-ripe due to lack of timely heat dissipation.
[0004] In summary, the existing wind-blown cooling and oil-draining device occupies too large an area, the recovered oil is contaminated, and the oil-draining efficiency is too low if it relies solely on gravity dripping and wind blowing. Moreover, if the broad beans are stacked to speed up the oil-draining, the fried broad beans at the bottom will become over-cooked because they cannot dissipate heat quickly. Therefore, it is impossible to achieve both rapid oil-draining and rapid cooling effectively. Utility Model Content
[0005] In response to the deficiencies in the prior art, the utility model provides a fried broad bean oil draining and cooling device, which solves the problems in the prior art of the air-blown cooling and oil draining device for fried broad beans, namely, that the device occupies too large an area, the recovered oil is contaminated, and the oil draining efficiency is too low when relying solely on gravity dripping and wind blowing. Furthermore, if the broad beans are stacked to speed up the oil draining, the fried broad beans on the bottom layer will be over-cooked because they cannot dissipate heat quickly, making it impossible to effectively achieve both rapid oil draining and rapid cooling.
[0006] According to an embodiment of the utility model, a fried broad bean oil draining and cooling device comprises a frame, two inner and outer cylinders of different sizes horizontally mounted on the frame and coaxially nested, a cooling assembly located inside the cylinders, and a driving assembly disposed on one side of the frame; the two cylinders are open at one end and closed at the other end, and the openings face the same direction, and a gap is provided between the closed ends of the two cylinders and between the cylinder walls;

[0008] The inner cylinder has an annular discharge port extending outward from the opening thereof. The annular discharge port is connected to the driving assembly, and the inner cylinder rotates with the rotation of the annular discharge port. The inner cylinder has a plurality of meshes evenly arranged on the wall thereof around the cylinder body.
[0009] The support mechanism is also provided with a feed port, the cooling component passes through the support mechanism and extends above the bottom wall of the inner cylinder, and an oil suction component is also provided between the outer cylinder and the inner cylinder near the opening area. The oil suction component absorbs the remaining grease on the surface of the material moved here and collects it into the inside of the outer cylinder.
[0010] Furthermore, a heat dissipation window is provided on the top of the outer cylinder, and a shield is provided in the area above the top of the heat dissipation window. Connecting rods are provided on the lower surfaces of both sides of the shield and are fixed to the top surfaces of both sides of the outer cylinder.
[0011] Furthermore, the support mechanism includes a support disc, and a plurality of connecting columns fixedly connected to the inner wall of the closed end of the outer cylinder are provided on the outer side surface of the support disc. The support disc is vertically connected to the closed end of the inner cylinder for rotation, and the side walls of the openings of the inner cylinder and the outer cylinder are connected for rotation.
[0012] Furthermore, a bearing is provided between the outer side wall of the inner tube opening and the inner side wall of the outer tube opening, and the inner tube realizes suspended rotation in the outer tube through the bearing and the supporting disc.
[0013] Furthermore, the driving assembly includes a motor and a pulley on the output end of the motor and a belt arranged on the annular discharge port. The pulley is connected to the belt on the outer wall of the annular discharge port. The motor drives the pulley to use the belt to drive the inner cylinder fixed to the annular discharge port to rotate in the outer cylinder.
[0014] Furthermore, the cooling assembly includes a heat exchange tube, in which a cooling medium is provided. The heat exchange tube passes through the closed end of the outer tube and the support disc and extends vertically downward to above the upper surface of the bottom of the inner tube, then extends horizontally toward the opening of the inner tube, and is bent back and forth to form a plate-like pipeline parallel to the upper surface of the bottom, with gaps left between the plate-like pipelines.
[0015] Furthermore, the oil absorption assembly includes an oil absorption layer that semi-surrounds one side of the opening area of the inner cylinder, and a squeezing roller arranged between the inner wall of the outer cylinder and the outer surface of the oil absorption layer. The squeezing roller is horizontally arranged and perpendicular to the rotation direction of the inner cylinder, and its two ends are rotatably connected to the inner wall of the outer cylinder. The squeezing roller has an interference fit with the oil absorption layer and squeezes the oil absorption layer.
[0016] Furthermore, a plurality of protrusions are evenly distributed on the contact surface between the oil-absorbing layer and the inner cylinder. The protrusions correspond to the meshes of the inner cylinder and can fit in with the meshes.

When the fried beans enter the rotating inner cylinder from the inlet, the inner cylinder rotates and the beans are cooled. During the process of beans being turned over by rotation, the oil on the surface will drip quickly during the collision of the beans and be filtered from the mesh. At the same time, the cooling component absorbs heat and cools the beans to prevent over-ripening. Because the beans are in motion, they will not accumulate, and the cooling component has a better heat absorption effect. A gap is left between the walls of the inner and outer cylinders to collect the drained oil, avoiding the oil from seeping into the inner cylinder again due to the lack of a gap between the inner and outer cylinders. An annular discharge port is also extended outward from the opening of the inner cylinder to collect the drained beans. When the driving component drives the annular discharge port to rotate, the inner cylinder rotates with the rotation of the annular discharge port. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0029] like Figure 1 、 Figure 2 As shown, an embodiment of the utility model proposes a fried broad bean oil draining and cooling device, comprising a frame 1, two inner and outer cylinders of different sizes horizontally mounted on the frame 1 and coaxially nested, a cooling component located inside the cylinder, and a driving component arranged on one side of the frame 1 for driving the inner cylinder 3 to rotate in the outer cylinder 2; the two cylinders are open at one end and closed at the other end and the openings are in the same direction, and there is a gap between the closed ends of the two cylinders and between the cylinder walls, a support mechanism is installed in the gap between the closed ends, and the gap between the inner and outer cylinder walls is used to collect the drained oil to prevent the oil from seeping into the inner cylinder 3 again due to the lack of a gap between the inner cylinder 3 and the outer cylinder 2.
[0030] The two cylinders include an outer cylinder 2 and an inner cylinder 3. The outer cylinder 2 is fixedly arranged on the top of the frame 1, and the inner cylinder 3 is rotatably arranged inside the outer cylinder 2. A support mechanism is coaxially provided between the closed ends of the inner cylinder 3 and the outer cylinder 2 to support the inner cylinder 3 in the outer cylinder 2; the inner cylinder 3 can be suspended in the outer cylinder 2 while rotating using the support mechanism.
[0031] like Figure 1As shown, the inner cylinder 3 is provided with an annular discharge port 4 extending outward from the opening thereof. The annular discharge port 4 is connected to the driving assembly, and the inner cylinder 3 rotates with the rotation of the annular discharge port 4. A plurality of meshes 32 are evenly arranged on the wall of the inner cylinder 3 around the cylinder body, so that when the broad beans collide with each other during the rotation of the inner cylinder 3, the oil attached to the surface of the broad beans is filtered by the meshes 32 and flows into the outer cylinder 2.
[0032] like Figure 1 、 Figure 2 and Figure 6 As shown, the support mechanism is also provided with a feed port 7, the cooling component passes through the support mechanism and extends above the bottom wall of the inner cylinder 3, and an oil absorption component is also provided between the outer cylinder 2 and the inner cylinder 3 near the opening area. The oil absorption component absorbs the remaining oil on the surface of the broad beans moved here and collects it into the inner part of the outer cylinder 2, and the annular discharge port 4 guides the processed broad beans to the outside of the device.
[0033] Further, such as Figure 1 、 Figure 5 and Figure 6 As shown, a heat dissipation window 21 is further provided on the top of the outer cylinder 2 to dissipate the heat of the broad beans themselves to the outside of the outer cylinder 2 to assist the cooling component in dissipating heat. A shield 211 is further provided in the area above the top of the heat dissipation window 21. Connecting rods 212 are provided on the lower surfaces of both sides of the shield 211 and are fixedly connected to the top surfaces of both sides of the outer cylinder 2. The connecting rods 212 are used to support the shield 211 suspended above the heat dissipation window 21 and prevent dust from falling into the interior of the device.
[0034] Further, such as Figure 2 、 Figure 3 and Figure 6 As shown, the support mechanism includes a support disc 32, and a plurality of connecting columns 321 are provided on the outer side surface of the support disc 32 to be fixedly connected to the inner wall of the closed end of the outer cylinder 2. The support disc 32 is vertically connected to the closed end of the inner cylinder 3 for rotation. The support disc 32 is coaxially embedded in the closed end of the inner cylinder 3, and four connecting columns 321 are provided on the outer side of the support disc 32 relative to the outside of the inner cylinder 3 for fixed connection with the inner bottom of the outer cylinder 2, so that the inner cylinder 3 rotates while the support disc 32 remains stationary. Figure 2 and Figure 4 As shown, a bearing 22 is provided between the outer side wall of the opening of the inner cylinder 3 and the inner side wall of the opening of the outer cylinder 2 , and the inner cylinder 3 realizes suspended rotation in the outer cylinder 2 through the bearing 22 and the support disc 32 .
[0035] Further, such as Figure 1 、 Figure 2 and Figure 8As shown, the driving assembly includes a motor 5 and a pulley 51 on the output end of the motor 5 and a belt 52 arranged on the annular discharge port 4. The pulley 51 is connected to the outer wall of the annular discharge port 4 by a belt. The motor 5 drives the pulley 51 to use the displacement of the belt 52 to drive the inner cylinder 3 fixed to the annular discharge port 4 to rotate stably in the outer cylinder 2.
[0036] Further, such as Figure 1 Figure 2 and Figure 6 As shown, the cooling assembly includes a heat exchange tube 8, which is provided with a cooling medium. The heat exchange tube 8 passes through the closed end of the outer tube 2 and the support disc 32, then extends vertically downward to above the bottom upper surface of the inner tube 3, and then extends horizontally toward the opening of the inner tube 3. It is bent back and forth to form a plate-like pipe 81 parallel to the bottom upper surface, with gaps left between the plate-like pipes 81. The bending of the heat exchange tube 8 and the gaps between the tubes increase the cooling area, thereby enhancing the cooling effect of the cooling assembly and accelerating the cooling speed. At the same time, the heat exchange tube is more convenient to clean than the heat sink. Only a cleaning tool such as a towel is needed to be wrapped around the tube body along the gap between the tubes to clean the residual grease on the heat exchange tube at one time, thereby preventing the grease from affecting the heat absorption effect of the heat exchange tube.
[0037] Further, such as Figure 2 、 Figure 6 and Figure 7 As shown, the oil absorption component includes an oil absorption layer 9 that semi-surrounds one side of the opening area of the inner cylinder 3. A plurality of protrusions 91 are evenly distributed on the contact surface between the oil absorption layer 9 and the inner cylinder 3. The protrusions 91 correspond to the meshes 32 of the inner cylinder 3 and can fit in with the meshes 32 so that the oil absorption layer 9 can contact the broad beans that have been initially drained with the help of these protrusions 91. After the protrusions 91 absorb the remaining oil on the surface of the broad beans, the broad beans are discharged from the annular discharge port 4. Figure 2 and Figure 6As shown, the squeezing roller 92 is horizontally arranged between the inner wall of the outer cylinder 2 and the outer surface of the oil-absorbing layer 9 and perpendicular to the rotation direction of the inner cylinder 3. Its two ends are rotatably connected to the inner wall of the outer cylinder 2 and can rotate freely. The squeezing roller 92 has an interference fit with the oil-absorbing layer 9 and squeezes the oil-absorbing layer 9. At the same time, when the inner cylinder 3 rotates, other areas of the oil-absorbing layer 9 body will gradually be squeezed with the squeezing roller 92, and the oil therein will be squeezed out of the oil-absorbing layer 9 and fall into the inner part of the outer cylinder 2 below under the action of gravity. During the squeezing process, some oil will be squeezed out again from the protrusions 91 at the mesh 32. However, because the squeezing area of the squeezing roller 92 changes as the inner cylinder 3 rotates, these oils will be absorbed by the resilient oil-absorbing layer 9 again. Even if some oil re-attaches to some broad beans, these oils are much less than before the oil draining treatment, and will not affect the flavor of the fried broad beans. Finally, in this repeated squeezing process, the oil in the oil-absorbing layer 9 will be slowly squeezed out by the squeezing roller 92. The oil-absorbing layer can be made of oil-absorbing cotton, which has strong adsorption capacity for oil and can be reused. It is not easy to decompose and will not contaminate the broad beans passing through its protrusions 91. The effect of recovering the final oil on the surface of the broad beans is better. Finally, the oil drained by the device can be processed and reused, such as preparing biofuel, soap and other chemical products, thereby improving resource utilization efficiency.
[0038] Further, such as Figure 1 and Figure 2 As shown, the center of the bottom of the outer cylinder 2 is concave downward to form a height difference with the surrounding area, and an oil outlet 6 is provided at the lowest point. The oil outlet 6 is provided at the bottom of the outer cylinder 2 and is located concave downward compared to the surrounding area, so that the grease is collected in one place and the grease does not flow out from the annular outlet 4 area.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
