Description

Technical Field

[0001] This invention relates to the field of oil pressing equipment technology, specifically to an integrated equipment for roasting and pressing crop seeds to extract oil. Background Technology

[0002] The seed roasting and pressing oil extraction equipment is an oilseed hot pressing processing machine that integrates roasting and maturation, material conveying, pressing and oil extraction, and crude oil filtration for oilseeds such as rapeseed, peanuts, sesame, sunflower, and soybeans. The oilseeds are first heated and roasted to destroy the oilseed cells and denature the proteins, reducing the viscosity of the oil. Then, while still hot, the oil is mechanically squeezed to separate the oil from the seeds, increasing the oil yield and giving the oil a rich aroma and flavor. It is a special equipment for hot pressing processes.

[0003] In related technologies, the grain roasting and pressing equipment mainly adopts a separate structure of roasting pan and oil press. However, the roasted oilseed grains need to be manually shoveled and transported before being put into the oil press feed hopper. This causes the hot grains to enter the press at a lower temperature during the open transport process, resulting in increased residual oil in the cake and a decrease in oil yield. Summary of the Invention

[0004] This invention provides an integrated equipment for roasting and pressing crop seeds to extract oil, which solves the problem in related technologies where the roasting pan and oil press are separate structures, requiring manual shoveling and transportation of seeds before they are fed into the oil press hopper, resulting in a decrease in the temperature of the seeds during transportation and a decrease in the oil yield.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated crop grain roasting and pressing oil extraction device, comprising a press body and a control cabinet. A feeding box is provided on the upper side of the press body. A roasting component is provided on the inner wall of the feeding box. The roasting component includes a buffer box.

A screening screen rotates on the lower side of the stir-frying plate. A processing tank is fixed on the outer wall of the screening screen. The inner wall of the processing tank slides on the inclined outer wall of the stir-frying plate away from the stirring column.

[0006] By adopting the above technical solution, the grains fall onto the auger blades inside the buffer box through the feed port. At this time, air is blown from the air inlet in conjunction with the tilt angle of the auger blades to transport and preheat the grains. The grains are then transported into the processing tank and fall onto the screening screen. At this time, the control cabinet starts the motor, which drives the stirring column and the frying plate to rotate synchronously. The frying plate continuously stirs the grains during rotation and periodically breaks up the cooked grains. The broken grains are then discharged through the screening screen to the lower side of the processing tank. The processing tank then transports the cooked grains into the press body for pressing to extract oil. When the processing tank is roasting and breaking up the grains, the air flow at the air inlet can be adjusted to achieve continuous feeding, roasting, and breaking up of the grains simultaneously.

[0007] Preferably, the upper surface of the processing tank is fixedly connected to the lower surface of the buffer box, the outer wall of the processing tank is fixedly connected to the inner wall of the feeding box, a conical block is fixedly connected to the lower inner wall of the processing tank, and the top of the conical block is fixedly connected to the lower surface of the screening screen.

[0008] Preferably, a butterfly valve is provided on the lower surface of the conical block, a pressure sensor is provided on the inner wall of the butterfly valve, and the outer wall of the pressure sensor is fixedly connected to the inner wall of the feeding box.

[0009] Preferably, an encoder is provided on the upper surface of the buffer box, a hollow column is fixedly connected to the inner wall of the buffer box, a fixing plate is fixedly connected to the lower surface of the hollow column, the outer wall of the fixing plate is fixedly connected to the inner wall of the buffer box, the outer wall of the hollow column is fixedly connected to the inner wall of the auger blade, and the outer wall of the stirring column passes through the inner walls of the hollow column and the fixing plate respectively.

[0010] Preferably, the inner wall of the hollow column is provided with an air supply pipe, the outer wall of the air supply pipe is fixedly connected to the inner wall of the buffer box, the lower inner wall of the buffer box near the fixed plate is provided with an exhaust pipe, and the inner wall of the fixed plate is provided with a connection port.

[0011] Preferably, a limiting ring is rotatably connected to the inner wall of the hollow column, and the inner wall of the limiting ring is fixedly connected to the outer wall of the stirring column.

[0012] Preferably, the inner wall of the stirring column has multiple sets of rectangular grooves, and the rectangular grooves are located on the upper side of the fixed plate. The lower inner wall of the stirring column near the fixed plate is provided with a guide groove.

[0013] Preferably, the inner wall of the stirring column is provided with a solenoid valve, and the inner walls of the stirring column located on the upper and lower sides of the solenoid valve are respectively provided with a first fixing pipe and a second fixing pipe.

[0014] Preferably, the outer wall of the first fixed tube is disposed on the inner wall of the stir-frying plate, and multiple sets of high-pressure nozzles are fixedly connected to the inner wall of the stir-frying plate, and an overflow valve is disposed on the inner wall of the stir-frying plate.

[0015] Preferably, the outer wall of the second fixing tube is disposed on the inner wall of the stir-frying plate, a dispersing rod is rotatably connected to the inner wall of the stir-frying plate, an impeller is fixedly connected to the outer wall of the end of the dispersing rod near the second fixing tube, the outer wall of the impeller is rotatably connected to the inner wall of the stir-frying plate, and a one-way valve is disposed on the inner wall of the stir-frying plate.

[0016] This invention provides an integrated device for roasting, pressing, and oil extraction of crop seeds. It has the following beneficial effects:

[0017] 1. This invention feeds material into the auger blades through the feeding port and preheats the material by introducing hot air through the air inlet. The material enters the screening screen, and the motor drives the stirring column and the frying plate to rotate synchronously for roasting. At this time, the frying plate, together with other structures, breaks up the cooked grains and discharges them through the screening screen into the feeding box and the press body for pressing. This preheating of the grains prevents them from being directly fed into the processing tank, which would cause the grains to be burnt on the outside and raw on the inside. Furthermore, the combination of the air inlet, auger blades, screening screen, and frying plate allows for continuous feeding, roasting, and pressing of the grains, achieving integrated roasting, pressing, and oil extraction. This prevents the grains from being exposed to the outside, which would lead to heat loss, increase the residual oil content in the cake, and reduce the oil yield.

[0018] 2. This invention uses a control cabinet and encoder to monitor the number of rotations of the stirring column, thereby controlling the feeding speed of the air inlet and auger blades and ensuring the butterfly valve feeds a fixed amount of material. The control cabinet also uses pressure sensors and encoders to prevent material from accumulating on the upper side of the butterfly valve. At the same time, the exhaust pipe extracts moisture from the upper side of the screening screen through the connection port, which can prevent moisture from accumulating in the processing tank and causing some grains to fail to rise, thus stabilizing the oil yield.

[0019] 3. In this invention, gas enters the rectangular trough and the stirring column. At this time, the gas will flow into the first fixed pipe and the second fixed pipe respectively. The high-pressure nozzle in the solenoid valve will spray gas to heat the inside of the grain. The second fixed pipe will control the impeller and the dispersing rod to rotate synchronously to disperse the cooked grain, which is convenient to be discharged through the screening screen. Moreover, the gas in the first fixed pipe and the second fixed pipe will be discharged into the processing tank through the one-way valve to prevent the formation of dead corners in the roasting process and improve the continuous production capacity of the equipment.

[0036] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see the appendix Figure 1 - Appendix Figure 5This invention provides an integrated crop grain roasting and pressing oil extraction device, including a press body 1 and a control cabinet 2. A feeding box 3 is provided on the upper side of the press body 1. A roasting component 4 is provided on the inner wall of the feeding box 3. The roasting component 4 includes a buffer box 41. The outer wall of the buffer box 41 is fixed to the inner wall of the feeding box 3. A feeding port 42 is provided on the upper inner wall of the buffer box 41. An air inlet 43 is provided on the side wall of the buffer box 41 at an angle. An auger blade 44 is fixed on the inner wall of the buffer box 41. A motor 45 is fixed on the top of the buffer box 41. A stirring column 46 is fixed on the output end of the motor 45. A stir-frying plate 47 is fixed on the outer wall of the stirring column 46. A screening screen 48 rotates on the lower side of the stir-frying plate 47. A processing tank 49 is fixed on the outer wall of the screening screen 48. The inner wall of the processing tank 49 slides on the inclined outer wall of the stir-frying plate 47 away from the stirring column 46.

[0038] Specifically, the pipe is connected to the feed port 42, and the pipe is used to continuously transport the grains. The grains enter the buffer box 41 and the motor 45 is started by the control cabinet 2. At the same time, the air inlet 43 can be connected to the hot air pipe. At this time, the grains fall onto the auger blade 44 inside the buffer box 41. The air inlet 43 is fixed to the inner wall of the buffer box 41 and is tilted at the same angle as the auger blade 44. At this time, the air inlet 43 will transport the grains on the auger blade 44 and preheat them. This can prevent the grains from directly entering the high-temperature cavity, which would cause the temperature difference between the inside and outside of the grains to cause the outside to burn and the inside to grow. Moreover, the moisture in the grains will quickly vaporize, which will increase the humidity in the cavity quickly. The grains are transported to the processing tank 49 by the auger blade 44 and the air inlet 43.

[0039] After the grains enter the processing tank 49, they fall onto the screening screen 48. At this time, the control cabinet 2 controls the motor 45 to start, causing the motor 45 to drive the stirring column 46 to rotate and simultaneously drive the stir-frying plate 47 to rotate. The stir-frying plate 47 slides on the upper surface of the screening screen 48 and the inner wall of the processing tank 49. Moreover, the bottom of one side of the outer wall of the stir-frying plate 47 is designed with an inclination, so that the stir-frying plate 47 will continuously stir-fry the grains during rotation. During the stir-frying, the stir-frying plate 47 will periodically break up the cooked grains, allowing the grains to pass through the screening screen 48 and be discharged to the lower side of the processing tank 49. The processing tank 49 will then transport the cooked grains. The material is fed into the feeding box 3. The four lower sides of the feeding box 3 are inclined and connected to the press body 1. The press body 1 is used to press the cooked seeds to extract oil. When the seeds are roasted and broken up in the processing tank 49, the air flow of the air inlet 43 can be adjusted to control the falling speed of the seeds. This creates a temperature difference between the first batch of seeds entering the processing tank 49 and the second batch. The first batch of seeds will be brittle and easy to break up after roasting. The second batch of seeds has a higher moisture content than the first batch, making it more difficult to break up. This allows for continuous feeding, roasting, and breaking up of the seeds at the same time.

[0040] Please see the appendix Figure 4and attached Figure 6 The upper surface of the processing tank 49 is fixedly connected to the lower surface of the buffer box 41. The outer wall of the processing tank 49 is fixedly connected to the inner wall of the feeding box 3. A conical block 491 is fixedly connected to the lower inner wall of the processing tank 49. The top of the conical block 491 is fixedly connected to the lower surface of the screening screen 48. A butterfly valve 492 is provided on the lower surface of the conical block 491. A pressure sensor 493 is provided on the inner wall of the butterfly valve 492. The outer wall of the pressure sensor 493 is fixedly connected to the inner wall of the feeding box 3.

[0041] Specifically, by fixing the feeding box 3, buffer box 41, and processing tank 49 together, a sealed space is formed inside. A conical block 491 is fixed to the lower side of the processing tank 49, and the top of the conical block 491 is fixed to the lower surface of the screening screen 48. This supports the screening screen 48 and allows the broken material falling from the screening screen 48 to fall onto the butterfly valve 492 through the inclined surface of the conical block 491. When the butterfly valve 492 is closed, it can prevent heat loss inside the processing tank 49 and prevent a large amount of broken seeds from directly accumulating in the feeding box 3 and the press body 1. Moreover, a pressure sensor 493 is installed on the inner wall of the butterfly valve 492 and is electrically connected to the control cabinet 2. When the pressure sensor 493 senses that the material accumulated on the butterfly valve 492 has reached a suitable value, the control cabinet 2 will control the butterfly valve 492 to open, allowing the butterfly valve 492 to quantitatively feed material into the press body 1, thus preventing fluctuations in the oil yield of the press body 1 during the pressing process.

[0042] Please see the appendix Figure 4 and attached Figure 5 An encoder 421 is provided on the upper surface of the buffer box 41. A hollow column 422 is fixedly connected to the inner wall of the buffer box 41. A fixing plate 426 is fixedly connected to the lower surface of the hollow column 422. The outer wall of the fixing plate 426 is fixedly connected to the inner wall of the buffer box 41. The outer wall of the hollow column 422 is fixedly connected to the inner wall of the auger blade 44. The outer wall of the stirring column 46 passes through the inner walls of the hollow column 422 and the fixing plate 426 respectively. An air supply pipe 423 is provided on the inner wall of the hollow column 422. The outer wall of the air supply pipe 423 is fixedly connected to the inner wall of the buffer box 41. An exhaust pipe 424 is provided on the lower inner wall of the buffer box 41 near the fixing plate 426. A connection port 425 is provided on the inner wall of the fixing plate 426.

[0043] Specifically, by mounting an encoder 421 on the upper surface of the buffer box 41, and the encoder 421 is used to monitor the number of revolutions of the stirring column 46 driven by the motor 45, this structure is existing technology and will not be described in detail here.

[0044] By setting three gears for encoder 421, when the stirring column 46 rotates to the first gear of encoder 421, encoder 421 will send a signal to control cabinet 2 and make air inlet 43 accelerate the blowing of air, thereby increasing the speed of grain feeding. When the stirring column 46 reaches the first gear of encoder 421, air inlet 43 stops accelerating the blowing of air and only maintains the normal air delivery rate.

[0045] When the stirring column 46 rotates between the first and second gears of the encoder 421, the internal structure of the stir-frying plate 47 will start to operate. When the stirring column 46 reaches the second gear of the encoder 421, the internal structure of the stir-frying plate 47 will stop operating.

[0046] When the stirring column 46 rotates to the third setting of the encoder 421, the encoder 421 will work with the control cabinet 2 to open the butterfly valve 492 for material discharge. If the pressure sensor 493 does not detect any accumulated particles on the butterfly valve 492, the butterfly valve 492 does not need to be opened. When the pressure sensor 493 detects material accumulated on the butterfly valve 492 but the material has not reached the threshold for the pressure sensor 493 to send a signal to the control cabinet 2 to open the butterfly valve 492, the stirring column 46 will work with the encoder 421 to control the control cabinet 2 to open the butterfly valve 492 for material discharge. This prevents the material from accumulating in the butterfly valve 492 and causing agglomeration. Furthermore, after the stirring column 46 rotates to the third setting of the encoder 421, the count will be reset and the calculation will start from the first setting.

[0047] By installing a fixing plate 426 on the inner wall of the buffer box 41, and with the stirring column 46 rotating on the inner wall of the hollow column 422 and the fixing plate 426, the stirring column 46 can achieve stable rotation. Furthermore, the upper side of the auger blade 44 is fixed to the inner wall of the buffer box 41, and the lower side of the auger blade 44 is fixed to the upper surface of the fixing plate 426. A hollow column 422 is fixed at the center of the auger blade 44, thus achieving sealed feeding and preventing grain accumulation on the auger blade 44. The fixing plate 426... The inner wall of the container has a connection port 425, and a filter screen is installed inside the connection port 425. When the lower side of the fixed plate 426 and the upper side of the screening screen 48 are roasted, the moisture of the grains will be transported through the connection port 425 to the upper side of the fixed plate 426 and the lower side of the auger blade 44. The moisture does not come into contact with the grains on the auger blade 44. At this time, the air is drawn out through the exhaust pipe 424 installed on the inner wall of the buffer box 41, which can prevent the moisture from accumulating inside the processing tank 49 and causing some grains to be undercooked.

[0048] Please see the appendix Figure 5 and attached Figure 6The inner wall of the hollow column 422 is rotatably connected to a limiting ring 427. The inner wall of the limiting ring 427 is fixedly connected to the outer wall of the stirring column 46. The inner wall of the stirring column 46 has multiple sets of rectangular grooves 471, and the rectangular grooves 471 are located on the upper side of the fixed plate 426. The lower inner wall of the stirring column 46 near the fixed plate 426 is provided with a guide groove.

[0049] Specifically, multiple sets of rectangular grooves 471 are opened on the inner wall of the stirring column 46, and the gas supply pipe 423 is fixed on the inner wall of the stirring column 46 and the buffer box 41 respectively. When hot gas is input into the gas supply pipe 423, the gas will enter the guide groove on the lower side of the stirring column 46 through the rectangular grooves 471. The outer wall of the stirring column 46 is fixed with a limiting ring 427, and the outer wall of the limiting ring 427 rotates on the inner wall of the hollow column 422, which can prevent the hot gas from rising through the outer wall of the stirring column 46.

[0050] Please see the appendix Figure 6 - Appendix Figure 8 The inner wall of the stirring column 46 is provided with a solenoid valve 472. The inner walls of the stirring column 46 located on the upper and lower sides of the solenoid valve 472 are respectively provided with a first fixed pipe 473 and a second fixed pipe 477. The outer wall of the first fixed pipe 473 is provided with the inner wall of the stir-fry plate 47. Multiple sets of high-pressure nozzles 475 are fixedly connected to the inner wall of the stir-fry plate 47. An overflow valve 476 is provided with the inner wall of the stir-fry plate 47. The outer wall of the second fixed pipe 477 is provided with the inner wall of the stir-fry plate 47. A dispersing rod 478 is rotatably connected to the inner wall of the stir-fry plate 47. An impeller 479 is fixedly connected to the outer wall of the end of the dispersing rod 478 near the second fixed pipe 477. The outer wall of the impeller 479 is rotatably connected to the inner wall of the stir-fry plate 47. A one-way valve 474 is provided with the inner wall of the stir-fry plate 47.

[0051] Specifically, by installing a solenoid valve 472 in the guide groove of the stirring column 46, when roasting, the solenoid valve 472 closes, so that the gas entering the rectangular groove 471 only enters the first fixed pipe 473. Since multiple sets of high-pressure nozzles 475 are installed on the upper inner wall of the stir-frying plate 47, and the overflow valve 476 blocks the gas to prevent it from flowing out, the gas enters unidirectionally from the first fixed pipe 473 and fills the space between the first fixed pipe 473 and the overflow valve 476. After replenishment, the gas is discharged from the high-pressure nozzles 475 and blown directly onto the grains. This replenishes the inside of the grains with hot gas to prevent only the upper layer of grains from being heated. Moreover, the high-pressure nozzle 475 can blow away impurities or shells attached to the outside of the grains, so that the grains can be heated evenly. When the pressure between the first fixed pipe 473 and the overflow valve 476 is too high, the overflow valve 476 will open to allow gas to flow to the one-way valve 474. After the pressure decreases, the overflow valve 476 will close. When the excess gas is discharged from the one-way valve 474, it will heat the inner wall of the processing tank 49, preventing the grains close to the inner wall of the processing tank 49 from experiencing a temperature drop.

[0052] When the solenoid valve 472 is opened, the gas flows into the first fixed pipe 473 and the second fixed pipe 477 respectively. Since the pressure between the first fixed pipe 473 and the overflow valve 476 cannot be increased, the gas mainly flows into the second fixed pipe 477. Through the one-way flow of the second fixed pipe 477, the gas can drive the impeller 479 to rotate, and the impeller 479 will drive the dispersing rod 478 to rotate synchronously, so that the two sets of dispersing rods 478 can disperse the cooked grains, thereby allowing the dispersed grains to be discharged through the sieve screen 48. Moreover, the gas in the second fixed pipe 477 cannot enter the first fixed pipe 473 through the overflow valve 476, so the gas is also discharged through the one-way valve 474 to achieve the heating effect.

[0053] Work process: The grains are fed into the buffer box 41 through the feed port 42. At this time, the control cabinet 2 starts the motor 45 and allows hot air to enter through the air inlet 43. The hot air, together with the auger blades 44, transports the grains and preheats them. The preheated grains are then transported to the screening screen 48. The motor 45 drives the stirring column 46, which in turn drives the stir-frying plate 47 to rotate and stir-fry the grains. At the same time, the encoder 421 monitors the number of rotations of the stirring column 46 in real time and controls the air flow rate through the air inlet 43 according to the number of rotations to adjust the grain feeding speed. The moisture generated by the grain roasting inside the processing tank 49 is extracted through the exhaust pipe 424 through the connection port 425 to avoid moisture retention and uneven grain ripening.

[0054] When encoder 421 monitors the stirring column 46 rotating to the first and second gear range, control cabinet 2 opens the solenoid valve 472 inside the stirring column 46, and hot air flows into the second fixed pipe 477, allowing the airflow to drive impeller 479 to rotate and disperse rod 478 to disperse the roasted grains. At this time, the grains accumulate along the inclined surface of cone block 491 to above butterfly valve 492. Pressure sensor 493 collects the material accumulation pressure above butterfly valve 492 in real time and opens it, allowing the roasted grains to fall into the press body 1 for pressing and oil extraction.

[0055] After the material is fed, the encoder 421 resets its count and restarts counting. The press body 1 receives the quantitatively fed cooked seeds and completes the pressing and oil extraction process.

[0056] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
