Description

Technical Field

[0001] The present application relates to the technical field of edible oil processing, and specifically discloses a roasting device for edible oil pressing. Background Art

[0002] The process of producing edible oil by pressing usually involves raw material processing, roasting, pressing and oil separation. Taking the production process of peanut oil as an example, the peanut kernels need to be cleaned and moldy or poor quality peanut kernels are excluded. Then the screened peanut kernels are washed, preliminarily dehydrated and roasted. The roasted peanut kernels are sent to the press for pressing to squeeze out peanut oil. The pressed peanut oil is then purified and filtered to obtain a clear and pure peanut oil product.

[0003] Among them, the roasting process plays a vital role in the production of peanut oil. It can effectively reduce the water content in the peanut kernel, thereby increasing the extraction rate of peanut oil, and can also reduce the possibility of microbial activity and extend the shelf life of peanut oil. Hot air roasting is a roasting technology that uses hot air and is widely used in the field of food processing and baking. Its basic principle is to heat the air to make it hot air, and then use this hot air to roast food to achieve the purpose of heating, drying and cooking.

[0004] At present, in the process of roasting peanut kernels by hot air roasting, multiple trays are placed in the drying box, and the peanut kernels are evenly spread on each tray for drying. Since one surface of the peanut kernels is in continuous contact with the tray and adjacent peanut kernels are in contact with each other, some parts of the peanut kernels cannot exchange heat with the hot air. Therefore, during the drying process, the peanut kernels on the tray need to be turned over regularly to make the heating and drying effect of the peanut kernels more uniform. Each time the peanut kernels are turned over, the drying box needs to be opened, resulting in heat loss in the drying box, causing energy waste. In addition, turning the peanut kernels many times also leads to greater labor intensity for the operators. Therefore, in view of this, the inventor provides a roasting device for edible oil pressing to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that in the process of roasting peanut kernels in a traditional drying box, the peanut kernels need to be turned over regularly, which causes heat loss in the drying box and causes energy waste.

[0006] In order to achieve the above-mentioned object, the basic scheme of the present invention provides a roasting device for pressing edible oil, comprising:

[0007] The box body has a feed bin and an air outlet duct at the top, and a discharge bin and an air inlet duct at the bottom;

[0008] A plurality of roasting frames are arranged vertically in the box body in sequence, the bottom surface of the roasting frame is composed of a plurality of blades rotatably connected to the side walls of the roasting frame, and a plurality of through holes are evenly arranged on the blades;

[0009] The driving mechanism drives the blades to rotate synchronously. When the blades are in a vertical state, the distance between adjacent blades is larger than the particle size of the peanut kernels. When the peanut kernels are roasted on the blades, the distance between adjacent blades is smaller than the particle size of the peanut kernels.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the present invention sets the bottom surface of the roasting frame in the form of multiple blades, so that by controlling the distance between adjacent blades, the peanut kernels can pass through the adjacent blades, so that the peanut kernels can be conveniently passed into each roasting frame or discharged from the roasting frame, and the roasting frame does not need to be removed during this process, so that the adding and discharging process of the peanut kernels is not only convenient to operate, but also avoids the roasting frame from scalding the operators due to the higher temperature, and the safety factor is higher. In addition, during the roasting process of the peanut kernels, the present invention uses a driving mechanism to drive the blades to rotate back and forth, thereby driving the peanut kernels on the blades to turn over, so that each surface of the peanut kernels is heated more evenly, replacing the process of regularly turning the peanut kernels during the roasting process of the traditional peanut kernels, which not only reduces the labor intensity of the operators, but also avoids the problem of heat loss in the box body caused by opening the box body, and solves the problem that during the roasting process of the traditional drying box, the peanut kernels need to be regularly turned over, resulting in heat loss in the drying box and causing energy waste.

[0012] Furthermore, a partition is provided in the box body, and the partition divides the box body into a roasting chamber and a driving chamber, and the roasting frames are all arranged in the roasting chamber. By providing the partition, the high temperature environment in the roasting chamber can be prevented from affecting the service life of other components in the driving chamber and the lubricating oil, and at the same time, the cleanliness of the hot air used for roasting peanut kernels is ensured, and the hot air is prevented from bringing impurities such as lubricating oil into the surface of the peanut kernels and affecting the quality of the finished peanut oil.

[0013] Furthermore, the driving mechanism comprises:

[0014] A plurality of sliding frames slidably connected to the partitions, racks slidably connected to the two sides of the roasting frame are respectively provided on both sides of the sliding frames, and the two sides of the roasting frame are rotatably connected to a rotating shaft, one end of the rotating shaft is connected to the blade, and the other end of the rotating shaft is provided with a gear meshing with the rack;

[0015] A first extrusion assembly includes a linear drive member and a plurality of sliders driven by the linear drive member and capable of respectively extruding each sliding frame, wherein when the sliders extrudes the sliding frame, the spacing between adjacent blades is greater than the particle size of the peanut kernel;

[0016] A second extrusion assembly includes a rotary drive member and a plurality of cams driven by the rotary drive member and capable of respectively extruding each sliding frame, wherein when the cams extrudes the sliding frame, the spacing between adjacent blades is smaller than the particle size of the peanut kernel;

[0017] The reset assembly comprises a retaining ring arranged on the sliding frame and a reset spring arranged between the retaining ring and the partition plate.

[0018] The slider is driven to move by the linear drive member, so that each slider squeezes each sliding frame respectively, so that each blade is in a vertical state, that is, the distance between adjacent blades is larger than the particle size of the peanut kernel, so that the peanut kernel is convenient to fall from the feed bin into each roasting frame and from each roasting frame to the discharge bin; and the rotary drive member drives each cam to rotate, so that each cam squeezes each sliding frame, so that each sliding frame moves back and forth, that is, the reciprocating rotation of each blade makes the blade appear to have a reciprocating swing effect, and then produces a back and forth oscillation effect on the peanut kernel on the blade, which can not only make the peanut kernel spread on the surface of each blade, but also make the peanut kernel more evenly heated during the roasting process. In this process, the reset spring uses its elastic potential energy to drive the sliding frame to reset.

[0019] Furthermore, protection boxes are respectively provided on both sides of the roasting frame, and the gear and the rack are both arranged in the protection boxes. The protection boxes can protect and isolate the gear and the rack.

[0020] Furthermore, the two adjacent gears on the same side of the roasting frame are staggered along the axis of the rotating shaft. At the same rotation angle, the spacing between adjacent blades increases with the increase of blade width, that is, reducing the blade width can effectively reduce the spacing between adjacent blades, and the reduction of the blade spacing will lead to a reduction in the spacing between two adjacent rotating shafts and two gears; and when the rack moves the same distance, the rotation angle of the gear decreases with the increase of the radius of the gear, and the smaller the rotation angle, the smaller the spacing between adjacent blades. The above arrangement can meet the requirements of using narrower blades and larger gears for matching, so as to avoid the situation where the spacing between adjacent blades is too large when the blades rotate back and forth, causing the peanut kernels to get stuck between the blades or roll off from between the blades.

[0021] Furthermore, the side walls of the sliding frame are provided with a push rod that can be pressed by the slider and a pressure plate that can be pressed by the cam. By configuring the length of the push rod and the thickness of the pressure plate, it is easier to cooperate with the slider and the cam to drive the rack to move different distances, that is, drive the blades to rotate different angles.

[0022] Furthermore, the length of the slider decreases from top to bottom, the length difference between adjacent sliders is greater than the diameter of the push rod, and the bottom of the slider is provided with an inclined surface that cooperates with the push rod. With this arrangement, when the peanut kernels are fed into each roasting frame through the feed bin, driven by the linear drive mechanism, each sliding frame sequentially breaks away from the contact with the slider from top to bottom, and the blades at the bottom of each roasting frame sequentially change from a vertical state to a parallel state from bottom to top, so that the peanut kernels fall into each roasting frame sequentially from bottom to top.

[0023] Furthermore, the feed bin includes a feed barrel arranged at the top of the box body and a hopper arranged at the top of the feed barrel, a feed shaft is rotatably connected in the feed barrel, a side wall of the feed shaft is provided with a plurality of feed blades rotatably connected along the inner wall of the feed barrel, and also includes a feed drive member driving the feed shaft to rotate. This method can effectively improve the sealing performance between the feed bin and the inside of the box body, can effectively reduce the loss of hot air in the box body, and reduce energy waste.

[0024] Based on the same inventive concept, the present invention provides a roasting method for edible oil pressing, comprising using the above-mentioned roasting device to roast peanut kernels after raw material processing.

[0025] Further, the steps of using the above-mentioned roasting device to roast the peanut kernels after the raw material processing are as follows:

[0026] Step S1, the peanut kernels after raw material processing are passed into the box body from the feed bin, and fall onto the leaves of each roasting frame respectively;

[0027] Step S2, hot air is introduced into the box through the air inlet duct to dry the peanut kernels on the blades, and at the same time, the driving mechanism drives each blade to rotate synchronously to drive the peanut kernels on the blades to turn over, so that each surface of the peanut kernels is heated more evenly;

[0028] Step S3, after roasting is completed, the driving mechanism drives each blade to be in a vertical state, so that the roasted peanut kernels are discharged from the discharge bin.

[0029] The method sets the bottom surface of the roasting frame in the form of multiple blades, so that by controlling the distance between adjacent blades, the peanut kernels can pass through the adjacent blades, so that the peanut kernels can be conveniently passed into each roasting frame or discharged from the roasting frame, and the roasting frame does not need to be removed during this process, so that the peanut kernel addition and discharge process is not only convenient to operate, but also avoids the roasting frame from scalding the operator due to the higher temperature, and the safety factor is higher. In addition, during the roasting of the peanut kernels, the present invention uses a driving mechanism to drive the blades to rotate back and forth, thereby driving the peanut kernels on the blades to turn over, so that each surface of the peanut kernel is heated more evenly, replacing the process of regularly turning the peanut kernels during the roasting of the traditional peanut kernels, which not only reduces the labor intensity of the operators, but also avoids the problem of heat loss in the box body caused by opening the box body, and solves the problem that during the roasting of the peanut kernels in the traditional drying box, the peanut kernels need to be regularly turned over, resulting in heat loss in the drying box and energy waste.

[0040] A roasting device for pressing edible oil, for example Figure 1 As shown: it includes a box body 1, a partition disposed in the box body 1, a plurality of roasting frames 9 disposed in the box body 1, and a driving mechanism, which are specifically as follows:

[0041] Box body 1: Box body 1 is supported and fixed by a plurality of supporting legs, a feed bin is arranged on the top of box body 1, a discharge bin 4 is arranged on the bottom of box body 1, an air inlet duct 7 is connected to the bottom side of box body 1, and an air outlet duct 8 is connected to the top of box body 1.

[0042] like Figure 2 As shown, the partition is vertically arranged in the box body 1, and divides the box body 1 into a roasting chamber and a driving chamber; a plurality of roasting frames 9 are stacked in sequence in the roasting chamber. In this embodiment, three roasting frames 9 are taken as an example for explanation, and a protective box 10 is arranged on the front and rear sides of each roasting frame 9.

[0043] like Figure 2 As shown, the driving mechanism includes a sliding frame slidably connected to the partition, a first extrusion assembly and a second extrusion assembly for respectively extruding the sliding frame, and the number of the sliding frames corresponds to the number of the roasting frames 9. In this embodiment, the number of the sliding frames is three, wherein the sliding frame includes symmetrically arranged sliding rods 12 and a connecting rod 11 arranged between the two sliding rods 12.

[0044] The first extrusion assembly includes a linear drive member 6 and a plurality of sliders 14 driven by the linear drive member 6 and capable of respectively extruding each sliding frame. The first extrusion assembly has two groups in total, which cooperate with the front and rear parts of the connecting rod 11 respectively. The linear drive member 6 can be any one of a cylinder, a hydraulic cylinder or an electric telescopic rod. The linear drive shaft 13 is connected to the output end of the linear drive member 6 to cooperate with the slider 14, thereby driving the slider 14 to move up and down. The number of the sliders 14 corresponds to the number of the sliding frames. In this embodiment, the number of the sliders 14 is three.

[0045] The second extrusion assembly includes a rotary drive member 5 and a plurality of cams 16 driven by the rotary drive member 5 and capable of respectively extruding each sliding frame. The second extrusion assembly cooperates with the middle portion of the connecting rod 11. The rotary drive member 5 can be a motor, and is connected to a rotary drive shaft through a reducer transmission. The number of cams 16 corresponds to the number of sliding frames. In this embodiment, the number of rotary drive shafts is three, and each cam 16 is arranged on the rotary drive shaft.

[0046] A limit sleeve is provided at the bottom of the box body 1, the bottom of the linear drive shaft 13 is slidably connected to the limit sleeve and passes through the bottom of the box body 1, and a rotating sleeve is also provided at the bottom of the box body 1, and the bottom of the rotating drive shaft is rotatably connected to the rotating sleeve.

[0047] like Figure 3 and Figure 4 As shown, the side walls of each connecting rod 11 are provided with a push rod that can be squeezed by the slider 14 and a pressure plate 17 that can be squeezed by the cam 16, and the bottom of the slider 14 is provided with an inclined surface that cooperates with the push rod. By configuring the length of the push rod, the thickness of the pressure plate 17 and the lateral distance of the inclined surface, when the slider 14 is out of contact with the push rod, the cam 16 and the pressure plate 17 are in contact with each other, and the push rod is not in contact with the linear drive shaft 13, thereby preventing the linear drive shaft 13 from affecting the cooperation between the cam 16 and the pressure plate 17.

[0048] like Figure 3 As shown, a reset assembly is provided on the sliding rod 12, wherein the reset assembly includes a retaining ring 19 provided on the sliding rod 12 and a reset spring 20 provided between the retaining ring 19 and the partition, and correspondingly, a fixing ring 18 is provided on the partition to cooperate with the reset spring 20.

[0049] like Figure 5As shown, one end of each sliding rod 12 passes through the partition and extends into the protection box 10, and is provided with a rack 21 slidably connected along the bottom of the protection box 10. The bottom surface of the roasting frame 9 is composed of a plurality of blades 23 rotatably connected to the side wall of the roasting frame 9. A plurality of through holes are evenly arranged on the blades 23. A rotating shaft is rotatably connected to the side wall of the roasting frame 9. One end of the rotating shaft is connected to the blade 23 and a sealing ring that fits the side wall of the roasting frame 9 is provided at the connection point. The corresponding side wall of the roasting frame 9 is provided with a sealing groove adapted to the sealing ring. The other end of the rotating shaft is provided with a gear 22 meshing with the rack 21. Two adjacent gears 22 are staggered along the axial direction of the rotating shaft.

[0050] In this embodiment, when the cam 16 cooperates with the pressure plate 17 to drive the sliding frame to move, and the blade 23 is driven to rotate by the cooperation of the gear 22 and the rack 21, the rotation position of the blade 23 is as follows: Figure 6 As shown in (a), (b), and (c), when the long end of the cam 16 cooperates with the pressure plate 17, the rack 21 moves to the left limit position, and the blade 23 rotates clockwise to the forward tilt limit position, as shown in FIG. Figure 6 As shown in (a), the rack 21 and the sliding rod 12 then move in the opposite direction under the action of the return spring 20, causing the blade 23 to rotate counterclockwise to a horizontal state, as shown in FIG. Figure 6 As shown in (b), gradually rotate counterclockwise to the reverse tilt limit position, as shown in Figure 6 As shown in (c), Figure 6 The position (b) is the equilibrium position of the spring, and Figure 6 (b) to Figure 6 (c) The state is driven by the elastic potential energy released after the spring is compressed. When the blade 23 is in Figure 6 In the states (a) and (c) shown in FIG. 1 , the distance between the two blades 23 is smaller than the size of the peanut kernel. When the slider 14 cooperates with the push rod to drive the sliding frame to move, and the blades 23 are driven to rotate by the cooperation of the gear 22 and the rack 21, the state of the blades 23 is as follows: Figure 6 As shown in (d), the distance between the two blades 23 is larger than the size of the peanut kernel.

[0051] The length of the sliders 14 in this embodiment decreases from top to bottom, and the length difference between adjacent sliders 14 is greater than the diameter of the push rod. Taking three sliders 14 and three push rods as an example, when the linear drive member 6 drives each slider 14 to the bottom, at this time, each slider 14 is in contact with each push rod, that is, the state of the leaves 23 in each roasting frame 9 is the same as Figure 6 As shown in (d), in this state, the peanut kernels on each blade 23 can be dumped into the discharge bin 4 for discharge; and the linear drive member 6 drives each slider 14 to move up one position. At this time, the bottom push rod is out of contact with the slider 14, while the two upper push rods are in contact with the slider 14, that is, the state of the blade 23 in the bottom roasting frame 9 is as follows: Figure 6 As shown in (b), the state of the blades 23 in the two upper roasting frames 9 is as follows Figure 6 As shown in (d), in this state, the peanut kernels in the feed bin pass through the two upper roasting frames 9 and fall into the roasting frame 9 at the bottom; the linear drive member 6 then drives each slider 14 to move up one position. At this time, the two lower push rods are out of contact with the slider 14, and the top push rod is in contact with the slider 14. The blades 23 of the two lower roasting frames 9 are in the state as shown in FIG. Figure 6 As shown in (b), the state of the blade 23 of the roasting frame 9 at the top is as follows Figure 6 As shown in (d), in this state, the peanut kernels in the feed bin pass through the top roasting frame 9 and fall into the roasting frame 9 in the middle; the linear drive member 6 then drives each slider 14 to move up one position, at which time all the roasting frames 9 are out of contact with the slider 14, and the blades 23 of all the roasting frames 9 are in the same state. Figure 6 As shown in (b), the peanut kernels in the feed bin fall into the roasting frame 9 at the top. The peanut kernels can be respectively fed into each roasting frame 9 for roasting.

[0052] like Figure 7 As shown, in the present embodiment, the feed bin comprises a feed barrel 3 arranged on the top of the box body 1 and a hopper 2 arranged on the top of the feed barrel 3. The top and bottom of the feed barrel 3 are respectively provided with openings connected with the hopper 2 and the box body 1. A feed shaft 24 is rotatably connected inside the feed barrel 3. The side wall of the feed shaft 24 is provided with a plurality of feed blades 25 rotatably connected along the inner wall of the feed barrel 3. A feed drive member for driving the feed shaft 24 to rotate is provided on the top of the box body 1. The feed drive member adopts a motor, which drives the feed shaft 24 to rotate by belt transmission.

[0053] During the implementation of this embodiment, the processed peanut kernels are introduced into the hopper 2, and then the linear drive 6 drives each slider 14 to move downward, so that the two upper push rods keep in contact with the slider 14 and the bottom push rod does not contact with the slider 14, and the feed drive is started to pass the peanut kernels into the bottom roasting frame 9; then the linear drive 6 intermittently drives each slider 14 to move upward, so that the peanut kernels can be respectively passed into the middle roasting frame 9 and the top roasting frame 9. After the peanut kernels are fed, the feed drive is closed; the air pump is used to pass the dried, filtered and heated hot air from the air inlet duct 7, and at the same time, the rotary drive 5 is started, and the hot air contacts the peanut kernels. The raw kernels are roasted in contact with each other, and the rotary drive member 5 cooperates with the pressing plate 17 through the cam 16 to drive the sliding frame to move, and the blades 23 are driven to rotate by the cooperation of the gear 22 and the rack 21, so that the blades 23 have a reciprocating swing effect, and then the peanut kernels on the blades 23 have a back and forth oscillation effect, which can not only make the peanut kernels spread on the surface of each blade 23, but also make the peanut kernels more evenly heated during the roasting process; after roasting is completed, the air pump that introduces hot air is turned off, and the rotary drive member 5 is turned off, and the linear drive member 6 drives each slider 14 to move downward to the bottom, so that the peanut kernels on each blade 23 can be dumped into the discharge bin 4 for discharge.

[0054] Based on the same inventive concept, the present invention provides a roasting method for edible oil pressing, comprising roasting peanut kernels after raw material processing using the above-mentioned roasting device, and the steps are as follows:

[0055] Step S1, the processed peanut kernels are passed into the hopper 2, and then the linear drive 6 drives each slider 14 to move downward, so that the two upper push rods keep in contact with the slider 14 and the bottom push rod does not contact the slider 14, and the feed drive is started to pass the peanut kernels into the bottom roasting frame 9; then the linear drive 6 intermittently drives each slider 14 to move upward, so that the peanut kernels can be respectively passed into the middle roasting frame 9 and the top roasting frame 9. After the peanut kernels are loaded, the feed drive is closed;

[0056] Step S2, using an air pump to introduce hot air that has been dried, filtered and heated from the air inlet duct 7, and starting the rotary drive member 5 at the same time, so that the hot air contacts the peanut kernels for roasting, and the rotary drive member 5 cooperates with the pressing plate 17 through the cam 16 to drive the sliding frame to move, and uses the cooperation of the gear 22 and the rack 21 to drive the blades 23 to rotate, so that the blades 23 have a reciprocating swing effect, and then produce a back and forth oscillation effect on the peanut kernels on the blades 23, which can not only make the peanut kernels spread on the surface of each blade 23, but also make the peanut kernels more evenly heated during the roasting process;

[0057] Step S3, after the roasting is completed, the air pump for introducing hot air is turned off, and the rotary drive member 5 is turned off, and the linear drive member 6 drives each slider 14 to move downward to the bottom, so that the peanut kernels on each blade 23 can be dumped into the discharge bin 4 for discharge.

[0058] Compared with the prior art, the present invention sets the bottom surface of the roasting frame 9 in the form of multiple blades 23, so that by controlling the spacing between adjacent blades 23, the peanut kernels can pass through the adjacent blades 23, so that the peanut kernels can be conveniently passed into each roasting frame 9 or discharged from the roasting frame 9, and the roasting frame 9 does not need to be removed during this process, so that the adding and discharging process of the peanut kernels is not only convenient to operate, but also avoids the roasting frame 9 from scalding the operator due to the higher temperature, and the safety factor is higher. In addition, during the roasting process of the peanut kernels, the present invention uses a driving mechanism to drive the blades 23 to rotate back and forth, thereby driving the peanut kernels on the blades 23 to turn over, so that each surface of the peanut kernels is heated more evenly, replacing the process of regularly turning the peanut kernels during the roasting process of the traditional peanut kernels, which not only reduces the labor intensity of the operators, but also avoids the problem of heat loss in the box body 1 caused by opening the box body 1, and solves the problem that the traditional drying box needs to regularly turn the peanut kernels during the roasting of the peanut kernels, resulting in heat loss in the drying box and energy waste.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
