Description

Technical Field

[0001] This invention relates to the field of edible rapeseed oil processing equipment, specifically to a rapeseed oil hydration device. Background Technology

[0002] After rapeseed oil is pressed, the phospholipids need to be separated from the oil to obtain clear edible rapeseed oil. Current methods for dephospholipid removal involve adding brine to the freshly pressed oil and stirring thoroughly. However, current equipment for dephospholipid removal uses a mixing drum. The pressed rapeseed oil is added to the drum, along with brine, and then the mixture is stirred at high speed to achieve the desired effect. This brine treatment can be seen as a simple "hydration and degumming" process. It removes some phospholipids and proteins, improving oil stability and reducing excessive foaming and smoke during cooking. The impurities are then separated from the brine using a centrifuge, resulting in hydrated rapeseed oil. Alternatively, the above equipment uses two sets of equipment for hydration and impurity removal. After hydration, the rapeseed oil is placed in a centrifuge to remove impurities, resulting in pure rapeseed oil. This process requires transporting the rapeseed oil, which is physically demanding for workers. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a rapeseed oil hydration device that facilitates automatic hydration and impurity removal of rapeseed oil without manual operation, thus improving efficiency. Furthermore, the device ensures uniform addition of brine, resulting in better hydration of the rapeseed oil.

A water passage hole communicating with the horizontal section of the squeeze dropper is opened on the outer wall of the first plug. A spring is fitted on the first plug to press it downward. When the first plug is lifted upward, the squeeze dropper drips salt water. The rotating component is a disc, which is mounted on a stirring shaft and driven by the stirring shaft. An arc-shaped notch is provided at the top of the disc, and the two sides of the notch are inclined. A roller is installed on the outer wall of the first plug, pressing against the top surface of the disc.

[0006] Preferably, the disc is mounted on the stirring shaft via bearings, and a differential assembly is provided between the stirring shaft and the disc to reduce the rotational speed of the disc. A lifting assembly is provided between the differential assembly and the top of the hydration cylinder.

[0007] Preferably, the annular pipe is provided with an inlet pipe and an outlet pipe. A pump is installed on the inlet pipe. The inlet pipe and the outlet pipe are connected to a water tank. A heating wire is installed in the water tank to heat the brine in the water tank. Multiple linkage valves are installed on the annular pipe. The position of the linkage valve corresponds to the position of the corresponding squeezing drip tube. When the first tube is blocked, the corresponding valve is closed, and the annular frame at the rear end of the squeezing drip tube is blocked.

[0008] Preferably, the bottom of the hydration cylinder is connected to a pipe, the other end of which is located directly above the centrifuge. Oil and water discharged from the pipe enter the centrifuge. The centrifuge includes a shell and a rotating cylinder, with the rotating cylinder embedded within the shell and rotatably fitted to it. An oil drain pipe is located at the center of the bottom of the rotating cylinder, and a valve is installed at the bottom of the drain pipe to seal its opening. The inner wall of the rotating cylinder is serrated, with each serration forming a groove. A slag discharge hole is provided in each groove on the inner wall of the rotating cylinder, and a sealing gate is hinged to each slag discharge hole. A sealing rubber ring is installed on the inner wall of the sealing door. A linkage ring is fitted on the outer wall of the rotating cylinder, and the linkage ring rotates with the outer wall of the rotating cylinder.

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] like Figure 1-12 The rapeseed oil hydration equipment includes a hydration cylinder 1, a brine addition mechanism 2, and a residue filtering mechanism 10. The brine addition mechanism 2 is installed on the hydration cylinder 1, and the residue filtering mechanism 10 is connected to the bottom of the hydration cylinder 1. The hydrated rapeseed oil in the hydration cylinder 1 enters the residue filtering mechanism 10 for residue filtering, thus obtaining clear rapeseed oil. A heating element 28, which is a heating coil, is installed on the inner wall of the hydration cylinder 1. Hot water at 85°C is continuously introduced into the heating coil to heat the tea seed oil in the hydration cylinder 1 to 85°C. A stirring shaft 29 is installed inside the hydration cylinder 1. Multiple stirring blades 30 arranged vertically are installed inside the stirring shaft 29 by welding. A plate is installed on the top of the hydration cylinder 1 by bolts. A motor is installed on the plate by bolts. The output shaft of the motor passes through the plate and is fixed to the stirring shaft 29 by welding. This enables the motor to drive the stirring shaft 29 to rotate. A brine adding mechanism 2 is installed at the top of the hydration cylinder 1. The brine adding mechanism 2 includes an annular tube 3 and a squeezing drip tube 6. The annular tube 3 is coaxial with the hydration cylinder 1. The outer wall of the annular tube 3 is fixed by a clamp, which is fastened to the top of the hydration cylinder 1 by bolts. A squeezing drip tube 6 is installed on the annular tube 3 in a ring shape by welding. The squeezing drip tube 6 extends into the hydration cylinder 1. A rotating component 31 is installed on the stirring shaft 29. The rotating component 31 rotates with the stirring shaft 29. The rotating component 31 triggers multiple squeezing drip tubes 6 in sequence to discharge high-temperature brine. The brine is dripped through the squeezing drip tubes 6 by the rotating component 31. Because the stirring speed is uniform, brine is added evenly, avoiding the emulsification of tea seed oil caused by adding a large amount of brine at once. In this way, the brine is added in multiple times, and the speed of adding brine is proportional to the stirring speed, so the hydration effect of tea seed oil is good. The bottom of the hydration cylinder 1 is connected to the filter mechanism 10 via a pipe. The bottom of the hydration cylinder 1 is a conical funnel. The rapeseed oil in the hydration cylinder 1 is transported through the pipe. A pump body is installed on the pipe through a threaded interface. The tea seed oil in the hydration cylinder 1 is transported through the pipe to the filter mechanism 10 for filtration. The filter mechanism 10 is a vertical centrifuge 11. An impurity removal component 16 is installed in the centrifuge 11. The clean oil is separated through the centrifuge 11. The impurities remaining in the centrifuge 11 are discharged through the impurity removal component 16. This eliminates the need for workers to stop the machine to clean the residue in the centrifuge 11.

[0028] The squeeze dropper 6 is a T-shaped pipe. One end of the squeeze dropper 6 is welded to and connected to the annular pipe 3. The annular pipe 3 contains heated high-temperature brine. The end of the squeeze dropper 6 away from the annular pipe 3 is vertically downward. A first plug tube 7 (hollow tube) is inserted into the vertical section of the squeeze dropper 6. The top of the first plug tube 7 is closed, and the outer wall of the first plug tube 7 is fitted to the inner wall of the squeeze dropper 6. A water passage hole 8 is opened on the outer wall of the first plug tube 7, which communicates with the horizontal section of the squeeze dropper 6. When the water passage hole 8 is connected to the horizontal section of the squeeze dropper 6... When the flow is open, the salt water on the horizontal section of the squeeze dropper 6 passes through the first plug 7 and enters the vertical section of the squeeze dropper 6. The bottom of the vertical section of the squeeze dropper 6 is open, so the salt water in the squeeze dropper 6 drips into the hydration tank. When the first plug 7 is misaligned with the horizontal section of the squeeze dropper 6, the squeeze dropper 6 becomes blocked. A spring is fitted on the first plug 7 to press it down. The top of the spring is fixed to the top of the first plug 7 by welding, and the bottom of the spring is fixed to the top of the vertical section of the squeeze dropper 6 by welding. The spring pulls the first plug 7 down. When the first plug 7 is lifted up, the squeeze dropper 6 drips salt water. When the first plug 7 is pressed down, the squeeze dropper 6 becomes blocked and cannot drip salt water. The rotating component 31 is a disc 32. A disc 32 driven by the stirring shaft 29 is installed on the stirring shaft 29. An arc-shaped notch 33 is opened at the top of the disc and near the circumference. The two sides of the notch 33 are beveled. A pressing device is installed on the outer wall of the first plug 7. The roller 34 is pressed against the top surface of the disc 32. The roller 34 is mounted on a straight rod by bearings. The straight rod is fixed to the top of the first plug tube 7 by bolts. When the roller 34 is pressed into the notch 33, the first plug tube 7 descends. As the disc 32 rotates, the roller 34 rolls from the notch 33 to the top of the disc 32, and the position of the roller 34 rises. At the same time, the position of the first plug tube 7 rises accordingly, thus squeezing the dropper 6 to drip salt water. In this way, the rotation of the disc 32 achieves the uniform addition of salt water.

[0029] The disc 32 is mounted on the stirring shaft 29 via bearings, allowing relative rotation between the disc 32 and the stirring shaft 29. A differential assembly 35 is positioned between the stirring shaft 29 and the disc 32. A vertical rail is welded to the stirring shaft 29 above the disc 32. The differential assembly 35 consists of planetary gears. The central gear of the planetary gears is fitted onto the vertical rail and the stirring shaft 29, allowing the central gear to move up and down along the stirring shaft 29. Clamping plates are installed on the upper and lower sides of the central gear, with the central gear mounted between the clamping plates via bearings. Planetary gears are mounted on the clamping plates via bearings. Gear rings meshing with the planetary gears are fitted around the outer circumference of multiple planetary gears, achieving differential speed from the central gear to the gear rings. An annular groove is formed on the circumference of the gear rings. A support plate is welded to the clamping plates, with one end of the support plate extending into the annular groove of the gear rings. This support plate lifts the gear rings. The bottom of the ring is fixed with multiple helical teeth arranged in a ring array by welding. The top of the disc 32 has a groove that meshes with the helical teeth. When the ring descends and meshes with the top of the disc 32, the ring drives the disc 32 to rotate. Since a planetary gear is used as the differential component 35, the stirring shaft 29 rotates quickly while the disc 32 rotates at a low speed, thus reducing the rotational speed of the disc 32. A lifting component 36 is set between the differential component 35 and the top of the hydration cylinder 1. The lifting component 36 is a telescopic electric cylinder. The cylinder body of the telescopic electric cylinder is fixed to the plate at the top of the hydration cylinder 1 by bolts. The piston rod of the telescopic electric cylinder is fixed to the clamping plate of the differential component 35 by welding. The lifting component 36 realizes the engagement and disengagement state between the differential component 35 and the disc 32. When the lifting component 36 descends, the differential component 35 drives the disc 32 to rotate.

[0030] An inlet pipe 4 and an outlet pipe 5 are fixed to the annular pipe 3 by welding. A pump is installed on the inlet pipe 4 via a threaded interface, drawing brine into the annular pipe 3. The inlet pipe 4 and outlet pipe 5 are connected to a water tank. An electrically powered heating wire is installed in the water tank by bolts, heating the brine in the tank. The pump then pumps the high-temperature brine from the tank into the annular pipe 3. Multiple linkage valves 9 are installed on the annular pipe 3 via threaded joints. Each linkage valve 9 corresponds to a drip tube. When each linkage valve 9 is closed, the annular pipe 3 downstream of that valve is blocked. The brine in the annular tube 3 can only flow out from the extrusion dropper corresponding to the linkage valve 9, ensuring that the brine in the extrusion dropper 6 is sprayed out under high pressure. If the annular tube 3 is open, the pressure in the extrusion dropper 6 is low, and the liquid pressure is low, so there is a situation where the extrusion dropper 6 cannot drip brine even when it is open. The position of the linkage valve 9 corresponds to the position of the corresponding extrusion dropper 6. When the first blockage tube 7 is put on, the corresponding valve is closed, and the annular frame at the rear end of the extrusion dropper 6 is blocked. A vertically set pressure sensor (model PT124G-210) is installed on the top of each extrusion dropper 6 by bolt fastening. When the roller 34 is located in the notch 33 of the disc 32, the straight rod presses on the pressure sensor. The linkage valve 9 is a solenoid valve, which is connected to the output end of the 51 microcontroller through a guide. Multiple pressure sensors are connected to the input end of the 51 microcontroller, and the pressure sensor corresponds to the corresponding solenoid valve. When one of the pressure sensors is not pressed, the corresponding linkage valve 9 is closed.

[0031] A pipe is connected to the bottom of the hydration cylinder 1, with the other end of the pipe located directly above the centrifuge 11. Oil and water discharged from the pipe enter the centrifuge 11. The centrifuge 11 includes a housing 12 and a rotating cylinder 13. The rotating cylinder 13 is embedded within the housing 12 and is mounted on the inner wall of the housing 12 via bearings at its bottom and top. A gear ring is welded to the top of the rotating cylinder 13. A motor is mounted on the outer wall of the housing 12, and a gear meshes with the gear ring on the motor's output shaft via welding. The motor drives the rotating cylinder 13 to rotate, and the rotating cylinder 13 rotates in conjunction with the housing 12. An oil drain pipe 14 is welded to the center of the bottom of the rotating cylinder 13. The top of the drain pipe is 10 cm above the bottom of the rotating cylinder 13, used to collect the upper layer of clear oil after centrifugation. The bottom of the rotating drum 13 contains a mixed oil containing filter residue, which needs to be filtered again before it can be used. A valve is installed at the bottom of the oil discharge pipe via a threaded joint. The oil can only be discharged when the valve is opened, and the bottom of the oil discharge pipe is sealed by the valve. The inner wall of the rotating drum 13 is serrated, and each serration of the rotating drum 13 is a groove 15. When the rotating drum 13 rotates, the filter residue is collected in the groove 15 by centrifugal force. A rectangular discharge hole 19 is opened in each groove 15 on the inner wall of the rotating drum 13. A sealing gate 20 is hinged to the outer wall of each discharge hole 19. A sealing rubber ring is installed on the inner wall of the sealing gate 20 by glue. When the sealing gate 20 is closed, the sealing rubber ring is pressed between the sealing gate 20 and the outer wall of the rotating drum 13, so that the sealing effect is good. When centrifugation is performed, the sealing gate 20 is closed. When it is necessary to discharge residue, the sealing gate 20 is opened, and the filter residue is discharged from the discharge hole 19 by centrifugal force.A linkage ring 21 is fitted onto the outer wall of the rotating cylinder 13, and a ring is fitted onto the linkage ring 21. The ring is fixed to the outer wall of the rotating cylinder 13 by welding, so that the linkage ring 21 rotates around the rotating cylinder 13. A connecting rod 22 is hinged between the linkage ring 21 and each sealing door 20. The rotation of the linkage ring 21 enables multiple sealing doors 20 to close and open simultaneously. Multiple inclined blocks 23 (the top surface of the inclined blocks 23 is inclined) are fixed to the top surface of the linkage ring 21 by welding. A pressing ring 24 is installed above the linkage ring 21. The inner wall of the pressing ring has a groove 15 that engages with the serrated outer wall of the rotating cylinder 13, so that the pressing ring moves up and down along the rotating cylinder 13. A clamping block 25, which contacts the inclined surface of the inclined block 23, is fixed by welding. The bottom surface of the clamping block 25 is inclined, and the inclined surface at the top of the inclined block 23 fits against the inclined surface at the bottom of the clamping block 25. Multiple hydraulic cylinders 26 are installed on the inner wall of the outer casing 12 by bolts. A pulley 27, which presses against the top of the clamping block 25, is mounted on the piston rod of the hydraulic cylinder 26 via bearings. A pressing ring 24 is engaged with the rotating cylinder 13 for lifting. A spring is fixed between the rotating cylinder 13 and the pressing ring 24 by welding. The spring moves the pressing ring 24 upward. When the hydraulic cylinder 26 rises, the pulley 27 presses the pressing ring 24 downward, thus blocking the slag discharge hole 19 of the sealing gate 20.

[0032] Each saw tooth on the inner wall of the rotating cylinder 13 is oblique, with one side of the saw tooth being an oblique surface and the other side of the saw tooth being parallel to the radius of the rotating cylinder 13. The slag discharge hole 19 is located on the surface of the saw tooth that is parallel to the radius, which facilitates the collection of filter slag.

[0033] The impurity removal component 16 is the flushing nozzle 17, which is fixed to the inner wall of the outer shell 12 by bolts. The flushing nozzle 17 is connected to the high-pressure pump through a water pipe. The flushing nozzle 17 flushes the interlayer between the inner wall of the outer shell 12 and the rotating cylinder 13. The interlayer between the inner wall of the outer shell 12 and the rotating cylinder 13 is a collection tank 47. The collection tank 47 is connected to the slag discharge port 18 that passes through the outer shell 12. The filter residue mixed with water after flushing has strong fluidity, so the filter residue is discharged from the slag discharge port 18.

[0034] A rotating ring 37 is fitted onto the outer wall of the unloading pipe at the top. The rotating ring 37 runs along the top of the unloading pipe. A swing arm 38 is mounted on the rotating ring 37 by a hinge. When the rotating cylinder 13 rotates, it increases the rotational lever arm. An arc-shaped groove is opened on the outer wall of the unloading pipe. A fixed baffle 39 is fixed to the inner wall of the unloading pipe by welding. A rotating baffle 40 is installed on the fixed baffle 39 by a rotational fit. A column is fixed to the fixed baffle 39 by welding. The column passes through the rotating baffle 40. The rotating baffle 40 is mounted on the fixed baffle 39. The rotating drum 13 rotates on the column 9. Holes for unloading are provided on the fixed baffle 39 and the rotating baffle 40. When the holes on the fixed baffle 39 and the rotating baffle 40 coincide, the unloading pipe unloads the oil. When the holes on the fixed baffle 39 and the rotating baffle 40 are misaligned, the unloading pipe becomes blocked. Before pouring the rapeseed oil, the rotating drum 13 rotates, and simultaneously, the rotating ring 37 rotates relative to the unloading pipe due to the inertia of the swing arm 38. This causes the holes on the fixed baffle 39 and the rotating baffle 40 to misalign. When the rotating drum 13 stops rotating, the oil inside the rotating drum 13... The oil pushes the rotating ring 37 to rotate relative to the unloading pipe, so that the holes on the fixed baffle 39 and the rotating baffle 40 coincide for unloading. A pressing spring 41 is placed at the bottom of the fixed baffle 39. An oil-sludge mixing hole 42 is opened at the bottom of the unloading pipe near the rotating cylinder 13. A second plug pipe 43 (the second plug pipe 43 is a hollow tube) is installed inside the unloading pipe and moves up and down. A hole communicating with the oil-sludge mixing hole 42 is opened in the second plug pipe 43. The bottom of the pressing spring 41 abuts against the top of the second plug pipe 43, and the pressing spring 41 presses the second plug pipe 43 downward. When the second plug 43 rises, the hole at the bottom of the unloading pipe connects with the hole on the second plug 43. When the second plug 43 descends, it blocks the oil-sludge mixing hole 42 at the bottom of the unloading pipe. A crankshaft 44 is installed on the inner wall of the bottom of the unloading pipe via a bearing. One end of the crankshaft 44 passes through the unloading pipe and is welded to the other end of the outer casing 12 with a turntable 45. A tie rod 46 is hinged between the crankshaft 44 and the second plug 43. Rotating the turntable 45 raises and lowers the second plug 43. When mixed oil needs to be discharged, the turntable 45 is rotated, and turbid mixed oil flows out of the unloading pipe.
