Description

Technical Field

[0001] The utility model relates to the technical field of edible oil production, in particular to an oil uniform feeding structure. Background Art

[0002] my country is a major producer of edible vegetable oil, and its consumption of vegetable oil ranks first in the world all year round. The main technologies for obtaining vegetable oil from oil are pressing, extraction, water substitution, etc., and pressing includes cold pressing and hot pressing. During cold pressing, the oil needs to be treated with microwaves for conditioning. During the conditioning process, such as: rapeseed, peanuts, sesame, sesame, tea seeds, etc., after heating to a certain temperature, the Maillard reaction can be promoted to produce a good rich flavor, which is beneficial to expand the cell oil channel and promote the trace nutrients in the oil. For example, the high-efficiency and energy-saving oil microwave conditioning equipment with the publication number CN108893186A combines a hot air pump with microwaves, and adds a heat preservation device at the same time, thereby improving the microwave efficiency and conditioning the oil.

[0003] However, during the microwave tempering process, the oil is not evenly distributed on the conveyor belt. After the oil enters the tempering equipment, the time required for microwaves to penetrate into oils of different thicknesses is different, which can easily lead to uneven heating of the oil and affect the tempering effect of the oil. Specifically, the thicker oil is not fully tempered, and the thinner oil will produce paste residue due to overheating, which in turn affects the quality of the final oil. Utility Model Content

[0004] In view of this, the utility model proposes an oil uniform feeding structure, by setting a uniform distribution member and a pressing gap between the uniform distribution member and the conveyor belt, and through the cooperation between the pressing surface and the receiving surface, the oil is evenly spread on the conveyor belt to a certain thickness, thereby avoiding the uneven thickness of the oil on the conveyor belt affecting the oil conditioning effect.

[0005] The technical solution of the utility model is implemented as follows: The utility model provides an oil uniform feeding structure, including a hopper, a microwave conveyor belt and a uniform distribution member, wherein:

[0006] The upper hopper includes a discharge portion, and the discharge portion is used to discharge the material in the upper hopper;

[0007] The microwave conveyor belt is arranged opposite to the upper hopper, and the microwave conveyor belt includes a material receiving surface, and the material receiving surface is used to receive the oil material dropped from the material discharge part and transmit it to the microwave tempering device;

[0008] The even distribution piece is arranged on the outer side of the upper hopper, and the even distribution piece includes a pressing surface, and a pressing gap is provided between the pressing surface and the receiving surface, and the pressing gap gradually becomes smaller along the feeding direction of the microwave conveyor belt. The pressing surface is used to gradually squeeze the oil and spread it onto the receiving surface through the pressing gap when the oil moves in the pressing gap.

[0009] On the basis of the above technical solution, preferably, an angle of 10°-20° is set between the material receiving surface and the material pressing surface.

[0010] On the basis of the above technical solution, preferably, the size of the maximum position of the pressing gap is 17-23 mm.

[0011] On the basis of the above technical solution, preferably, the size of the minimum position of the pressing gap is 7-13 mm.

[0012] On the basis of the above technical solution, preferably, it also includes a fine-tuning component, which is arranged on the upper hopper, and the uniform distribution member is relatively fixed to the upper hopper through the fine-tuning component, and the fine-tuning component is used to adjust the size of the pressing gap between the pressing surface and the receiving surface.

[0013] Further preferably, the fine-tuning assembly includes a screw and a locking member, wherein:

[0014] The screw is fixed on the upper hopper, and the end of the uniform distribution member away from the pressing surface is sleeved on the screw;

[0015] The locking piece is threadedly connected to the screw rod and abuts against the evenly distributing piece. The locking piece is used to adjust the horizontal position of the evenly distributing piece through the thread.

[0016] Further preferably, at least two oval holes are formed on the evenly distributing member, and the fine-tuning assembly includes at least two fixing members, and the fixing members pass through the oval holes to fix the evenly distributing member to the upper hopper.

[0017] On the basis of the above technical solution, preferably, it further comprises a support plate, which is arranged opposite to the microwave transmission belt and is located on the other side of the material receiving surface of the microwave transmission belt, and the support plate is used to support the microwave transmission belt.

[0018] Further preferably, it also includes a buffer component, which is fixed relative to the upper hopper, and the buffer component has an elastic end, and the support plate is fixed on the elastic end of the buffer component so that the support plate can move under the deformation of the microwave transmission belt.

[0019] More preferably, the buffer assembly includes a fixing plate and an elastic member, wherein:

[0020] The fixed plate is relatively fixed to the upper hopper, and the support plate is movably arranged on the fixed plate;

[0021] One end of the elastic member is fixedly connected to the fixing plate, and the other end is fixed to the supporting plate.

[0022] The oil uniform feeding structure of the utility model has the following beneficial effects compared with the prior art:

[0023] (1) By arranging the uniform distribution member on the outside of the material discharging part and on the side of the material discharging part facing the microwave tempering device, after the material is discharged from the material discharging part onto the microwave conveyor belt, the oil will contact the uniform distribution member as the microwave conveyor belt moves, and the thickness is controlled within a relatively small range under the extrusion of the material pressing surface and the material receiving surface, and the material pressing gap gradually becomes smaller along the feeding direction of the microwave conveyor belt, thereby breaking up the oil that is stuck together and spreading it on the material receiving surface of the microwave conveyor belt together with the oil with uneven thickness, thereby preventing the uneven thickness of the oil on the conveyor belt from affecting the oil tempering effect;

[0025] (3) By setting up a buffer component, when the oil size is large or the agglomerated oil has a high viscosity, the microwave conveyor belt will be squeezed and deformed when transmitting such oil, and this deformation will be reflected on the support plate, generating a certain pressure on the support plate. When the pressure is greater than the deformation threshold of the buffer component, the buffer component will be compressed and deformed, so that the support plate will be displaced through the elastic section of the buffer component, avoiding hard contact between the microwave conveyor belt and the oil, thereby protecting the microwave conveyor belt.

[0031] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1 As shown, the oil uniform feeding structure of the utility model comprises an upper hopper 1, a microwave conveyor belt 2 and a uniform distribution member 3.

[0033] The upper hopper 1 includes a discharge portion 11, which is used to discharge the material in the upper hopper 1. A straight-edge is provided on the discharge portion 11, and the length of the straight-edge is slightly smaller than the width of the microwave conveyor belt 2. In actual production, the oil is pumped upward into the upper hopper 1 by a suction machine, and the oil falls onto the microwave conveyor belt 2 through the discharge portion 11 of the upper hopper 1 under the action of gravity.

[0034] The microwave conveyor belt 2 is arranged opposite to the upper hopper 1, and the microwave conveyor belt 2 includes a material receiving surface 201. The material receiving surface 201 is used to receive the oil falling from the discharge part 11 and transmit it to the microwave tempering equipment. Reversing cabinets are set at both ends of the microwave conveyor belt 2. The microwave conveyor belt 2 completely passes through the microwave tempering equipment. The oil falling from the upper hopper 1 will be received by the microwave conveyor belt 2 and sent to the microwave tempering equipment. After the oil tempering is completed, the oil will be discharged from the other end of the microwave conveyor belt 2 and collected by components such as the unloading slide and the material receiving trough, waiting for the next process. The material receiving surface 201 is the side of the microwave conveyor belt 2 facing the discharge part 11, and the oil discharged from the discharge part 11 will fall onto the material receiving surface 201. It should be noted that the material receiving surface 201 does not change its spatial position with the rotation of the microwave conveyor belt 2.

[0035] The even distribution member 3 is arranged on the outside of the upper hopper 1, and the even distribution member 3 includes a pressing surface 301. There is a pressing gap between the pressing surface 301 and the receiving surface 201, and the pressing gap gradually becomes smaller along the feeding direction of the microwave conveyor belt 2. The pressing surface 301 is used to gradually squeeze the oil and spread it onto the receiving surface 201 through the pressing gap when the oil moves in the pressing gap.

[0036] In this embodiment, the uniform distribution member 3 is arranged on the outside of the discharge portion 11 and is located on the side of the discharge portion 11 facing the microwave tempering equipment. After the discharge portion 11 discharges the oil onto the microwave conveyor belt 2, as the microwave conveyor belt 2 moves, the oil will contact the uniform distribution member 3, and under the extrusion of the pressing surface 301 and the receiving surface 201, the thickness is controlled within a smaller range, and the pressing gap gradually becomes smaller along the feeding direction of the microwave conveyor belt 2, thereby breaking up the oil that is stuck together and spreading it on the receiving surface 201 of the microwave conveyor belt 2 together with the oil of uneven thickness. It should be noted that if the widths of the two ends of the pressing gap are the same, the agglomerated oil will not be able to enter the pressing gap, which will result in the presence of agglomerated oil on the path of the agglomerated oil when the oil enters, and the oil will be spread thinly, resulting in overheating of this part of the oil during the tempering process.

[0037] In the present embodiment, since the pressing gap is set from wide to narrow, there is an acute angle between the receiving surface 201 and the pressing surface 301, and the angle of the acute angle can be set to 10°-20°. It should be noted that if the setting angle is less than 10°, in order to ensure that the agglomerated oil can enter the pressing gap and the oil spread on the microwave conveyor belt 2 can be evenly distributed, it is necessary to extend the length of the pressing surface 301 projected on the receiving surface 201. Too long will cause the space required for the uniform distribution member 3 to increase. If the setting angle is greater than 20°, the extrusion angle will be too large, resulting in the microwave conveyor belt 2 being unable to drive the agglomerated oil or oil with larger particles to move through friction, resulting in material jamming. The angle between the receiving surface 201 and the pressing surface 301 is preferably set to 15°. At this angle, the space occupied by the uniform distribution member 3 is more reasonable, and there will be no material jamming.

[0038] In this embodiment, the size of the maximum position of the pressing gap is 17-23 mm, and is preferably 20 mm. This setting needs to satisfy that the pressing gap is larger than the maximum size of the oil particles, and at the same time, it can allow agglomerated oil to enter and be squeezed through the pressing gap, so that the agglomerated oil can be dispersed and spread flat on the microwave conveyor belt 2.

[0039] Correspondingly, the size of the minimum position of the pressing gap is 7-13mm, and is preferably 10mm. The largest particle of oil is generally around 10mm. The minimum position of the pressing gap needs to satisfy the requirement that the largest oil particle can pass through this position and move with the microwave conveyor belt 2. It should be noted that even if the largest oil particle is larger than 10mm, its size will not exceed too much. The deformation of the microwave conveyor belt 2 and the friction formed between the microwave conveyor belt 2 and it can drive the large particle of oil to leave the pressing gap.

[0040] During the production process, due to the influence of installation accuracy and production accuracy, when the uniform distribution member 3 is installed on the upper hopper 1, the size of the pressing gap between the uniform distribution member 3 and the microwave transmission belt 2 cannot be accurately controlled. Therefore, a fine-tuning component 4 is also provided in this embodiment. The fine-tuning component 4 is provided on the upper hopper 1, and the uniform distribution member 3 is relatively fixed to the upper hopper 1 through the fine-tuning component 4. The fine-tuning component 4 is used to adjust the size of the pressing gap between the pressing surface 301 and the receiving surface 201.

[0041] like Figure 1-3 As shown, the uniform distribution member 3 is installed on the upper hopper 1 through the fine-tuning component 4. After installation, the horizontal position of the uniform distribution member 3 can be adjusted through the fine-tuning component 4, so as to adjust the size of the pressing gap to achieve the optimal size.

[0042] like Figure 2 As shown, in a specific embodiment, the fine-tuning component 4 includes a screw 41 and a locking piece 42, the screw 41 is fixed on the upper hopper 1, the end of the uniform distribution member 3 away from the pressing surface 301 is sleeved on the screw 41, the locking piece 42 is threadedly connected to the screw 41 and abuts against the uniform distribution member 3, and the locking piece 42 is used to adjust the horizontal position of the uniform distribution member 3 through a thread, wherein the number of the locking pieces 42 is two, the screw 41 is set to be perpendicular to the horizontal plane, and the uniform distribution member 3 is set in a U shape, which is far away from the pressing surface 301. A mounting hole is provided on the side away from the pressing surface 301, through which the screw 41 passes through the uniform distribution member 3, and two locking members 42 are threadedly connected to the screw 41, thereby fixing the uniform distribution member 3 on the screw 41. The two locking members 42 are respectively located on both sides of the mounting hole. When fine-tuning is required, one of the two locking members 42 can be twisted to loosen the uniform distribution member 3, and then the other locking member 42 can be twisted to lock and fix the uniform distribution member 3 here, thereby fine-tuning the horizontal position of the uniform distribution member 3.

[0043] like Figure 3 As shown, in another specific embodiment, at least two oval holes 302 are provided on the uniform distribution member 3, and the fine-tuning component 4 includes at least two fixing members 43, and the fixing members 43 pass through the oval holes 302 to fix the uniform distribution member 3 to the upper hopper 1. The fixing members 43 can use bolts, and a vertical plate needs to be installed on the upper hopper 1 first, and circular holes corresponding to the two fixing members 43 are provided on the vertical plate, and then the uniform distribution member 3 is placed on the side of the vertical plate, and the fixing members 43 are used to fix the vertical plate and the uniform distribution member 3. For the adjustment of the horizontal position of the uniform distribution member 3, the fixing members 43 can be loosened, and the uniform distribution member 3 can be moved vertically through the oval holes 302, so as to realize the size adjustment of the pressing gap.

[0044] Taking into account that the microwave conveyor belt 2 has a certain elasticity, during the transmission process, the agglomerated oil may be deformed by pressing the microwave conveyor belt 2 and leave the pressing gap. In order to increase the probability of dispersing the agglomerated oil, a support plate 5 is also provided in this embodiment. The support plate 5 is arranged opposite to the microwave conveyor belt 2 and is located on the other side of the material receiving surface 201 of the microwave conveyor belt 2. The support plate 5 is used to support the microwave conveyor belt 2. The microwave conveyor belt 2 is supported by the support plate 5, thereby improving the deformation resistance of the material receiving surface 201, so that greater pressure can be applied to the agglomerated oil during the movement to disperse and spread it flat.

[0045] In order to prevent oil of extreme size from being blocked by the support plate 5 during transportation and causing jamming or wear of the microwave conveyor belt 2, a buffer component 6 is provided. The buffer component 6 is relatively fixed to the upper hopper 1. The buffer component 6 has an elastic end. The support plate 5 is fixed on the elastic end of the buffer component 6 so that the support plate 5 can move under the deformation of the microwave conveyor belt 2.

[0046] When the oil is large in size or the agglomerated oil has a high viscosity, the microwave conveyor belt 2 will be squeezed and deformed when transmitting such oil, and this deformation will be reflected on the support plate 5, generating a certain pressure on the support plate 5. When the pressure is greater than the deformation threshold of the buffer component 6, the buffer component 6 will be compressed and deformed, so that the support plate 5 is displaced through the elastic section of the buffer component 6, avoiding hard contact between the microwave conveyor belt 2 and the oil.

[0047] Specifically, Figure 4 As shown, the buffer assembly 6 includes a fixed plate 61 and an elastic member 62. The fixed plate 61 is relatively fixed to the upper hopper 1. The support plate 5 is movably arranged on the fixed plate 61. One end of the elastic member 62 is fixedly connected to the fixed plate 61, and the other end is fixed to the support plate 5. The elastic member 62 can be selected as a spring. At the same time, a guide rod needs to be arranged on the support plate 5, so that the guide rod passes through the fixed plate 61, and the elastic member 62 is sleeved on the guide rod. The elastic member 62 is deformed to make the support plate 5 move slightly, so that extremely large particles of oil can pass through the pressing gap, and after passing through, the elastic member 62 pushes the support plate 5 to return to its original position.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
