Description

Technical Field

[0001] The invention belongs to the technical field of oil production, and in particular relates to a production process of edible oil. Background Art

[0002] Edible oil is a kind of condiment needed in daily life. It is basically extracted from plants. Edible oil includes many kinds, such as tea oil, peanut oil, etc. Tea oil has a special aroma and is rich in nutrients. In recent years, as the market share of tea oil has increased year by year, it has become more and more popular among the public. In the actual production of tea oil, the collected tea seeds are cleaned and graded, the impurities in the tea seeds are removed, and then the shells are peeled. The shelled tea seeds are steamed and fried, and then pressed. The crude oil is filtered, deodorized and other subsequent processes are carried out, and edible camellia oil can be finally obtained. The squeezed tea residue can also be used as a raw material for toiletries or for fertilization.

[0003] The pressing process usually uses a more efficient screw oil press. The screw oil press uses a rotating screw shaft to continuously push the blank in the pressing chamber. As the spiral lead on the pressing screw gradually shortens or the thread depth gradually becomes shallower, the space volume in the pressing chamber (pressing chamber volume or free volume) gradually decreases, thereby producing a pressing effect, squeezing the oil out of the gap in the pressing cage, and the residue is compressed and discharged from the outlet end. However, the residue is discharged from the outlet end in the form of flakes. The volume is too large to fall into the discharge port below, and it is easy to accumulate too much and escape from the top. In addition, the discharge volume from the lower discharge port is large, which will occupy too much space, so that the collection frame can only hold a small amount of residue before it is full. Summary of the invention

[0004] The purpose of the present invention is to provide a production process for edible oil in view of the above-mentioned technical problems, so as to achieve the effect of making tea residues fall smoothly and increasing the residue receiving amount of the material frame.

[0005] In view of this, the present invention provides a production process of edible oil, comprising:

[0006] S1: Drying: Use a dryer to dry the camellia seeds, set the temperature of the dryer to 60°C, and when the temperature drops by 58°C, the blower of the dryer blows until the temperature reaches 60°C, then the blower stops blowing, so that the furnace temperature of the constant temperature hot air dryer is maintained between 58°C and 60°C to dry the camellia seeds;

[0007] S2: Shelling: a shelling machine shells the camellia seeds, and then the camellia seeds are sent to a mold separator to remove moldy camellia seeds;

[0008] S3: Steaming and frying, using a steaming and frying pan to steam and fry the camellia seeds, the heat transfer oil boiler of the steaming and frying pan controls the temperature of the heat transfer oil to be maintained between 62°C and 65°C through a thermostatic controller, and the steaming and frying time of the steaming and frying pan is 30-35 minutes;

[0009] S4: pressing, using a screw oil press to press the camellia seeds to obtain raw camellia oil, and the screw oil press can crush the residue;

[0010] S5: Filtration and refining: The crude oil initially obtained needs to be coarsely filtered and finely filtered to remove solid particles and some impurities. Subsequently, degumming, deacidification and other refining processes may be required to obtain edible camellia oil.

[0011] In the technical solution, the tea dregs are broken into pieces so that they can smoothly fall into the material frame below the discharge port, and after being broken into pieces of small size, they will not occupy too much space, thereby increasing the dregs receiving capacity of the material frame.

[0012] Furthermore, the screw oil press comprises a frame, on which are provided:

[0013] The blasting shell is fixedly arranged on the frame, a plurality of pressing rings with end faces fitting are fixedly arranged in the blasting shell, an oil outlet groove is provided on the pressing ring, a pressing screw is passed through the blasting shell, the pressing screw and the pressing ring are coaxially arranged in the inner ring of the pressing ring, a gap exists between the outer periphery of the pressing screw and the inner ring of the pressing ring, the depth of the pressing screw thread gradually becomes shallower along the feed inlet to the discharge outlet of the blasting shell, the pressing screw is connected to the oil pressing power component and can rotate circumferentially, a crushing component is provided at the feed inlet of the blasting shell, and the crushing component is used to crush the tea residue discharged from the inlet and outlet of the blasting shell;

[0014] A feeding hopper is arranged above the feeding port of the bursting shell, and a stirring assembly is arranged in the feeding hopper to make the tea seeds in the feeding hopper fall into the bursting shell;

[0015] The oil receiving pan has an opening below the frying shell. The oil receiving pan is arranged below the frying shell and is used to receive the tea oil flowing out of the oil outlet groove of the pressing ring.

[0016] In the present technical scheme, after the tea seeds are put into the feed hopper, the stirring component stirs to promote the tea seeds to enter the space between the outer periphery of the pressing screw and the inner periphery of the pressing ring in the explosion shell in an orderly manner. The tea seeds that fall into the transmission of the pressing screw move toward the discharge port of the explosion shell. Because the depth of the pressing screw thread from the feed port to the discharge port of the explosion shell gradually becomes shallower, the tea seeds will be squeezed out of the tea oil due to the reduction of space. The tea oil flows out from the oil groove on the pressing ring to the oil receiving tray, and the tea residue is flattened and discharged from the discharge port of the explosion shell. However, the tea residue is discharged from the outlet end in a continuous sheet shape. The volume is too large and it is not easy to fall into the discharge port below. It is easy to accumulate too much and escape from the top. Moreover, the discharge volume from the lower discharge port is large, which will occupy too much space, so that the material frame for collection can only be filled with a small amount of residue. The folding component is provided to fold the tea residue, so that the tea residue can smoothly fall into the material frame below the discharge port, and after folding, it becomes small-volume fragments, which will not occupy too much space, thereby increasing the slag receiving capacity of the material frame.

[0017] Furthermore, the oil pressing power assembly comprises:

[0018] An oil pressing motor, wherein the oil pressing motor is fixedly arranged on the frame, an output end of the oil pressing motor is connected to a transmission shaft, and a first gear is sleeved on the transmission shaft;

[0019] The second gear is fixedly arranged at the end of the squeezing screw and meshes with the first gear.

[0020] Furthermore, the stirring assembly comprises:

[0021] A stirring shaft, wherein the stirring shaft is arranged in the feed hopper, a tea-pushing rod is arranged on the outer periphery of the stirring shaft, and a first bevel gear is arranged on the upper end of the stirring shaft;

[0022] A conversion shaft, wherein the conversion shaft and the stirring shaft are vertically arranged above the feed hopper, one end of the conversion shaft is fixedly connected to the first flywheel, and the other end is fixedly connected to the second bevel gear, the first bevel gear is meshed with the second bevel gear, the transmission shaft extends from the inside of the frame to the outside of the frame, the transmission shaft is fixedly connected to the second flywheel, and the belt tensioning sleeve is arranged on the outer periphery of the second flywheel and the first flywheel so that the second flywheel transmits the circumferential rotational force to the first flywheel.

[0023] In the present technical scheme, the oil pressing motor is started to rotate the transmission shaft, driving the pressing screw to rotate to press the oil. At the same time, the second flywheel rotates to drive the first flywheel to rotate, so that the conversion shaft and the second bevel gear rotate, thereby causing the first bevel gear to rotate with the stirring shaft and the tea-push rod, thereby stirring the tea seeds in the feed hopper, promoting the tea seeds to fall into the explosion shell better, and preventing blockage. The stirring and oil pressing share the power source, which can save energy.

[0024] Furthermore, the stirring shaft extends downward into the explosion chamber shell and is provided with an auger.

[0025] In the technical solution, the auger can promote the tea seeds to fall evenly onto the pressing snail.

[0026] Furthermore, the crushing assembly comprises:

[0027] A fixed plate, the fixed plate is fixedly arranged on the frame near the discharge port of the burst shell, and two sets of opposite brackets are arranged on the fixed plate, and a cross bar is slidably arranged on each set of brackets;

[0028] A first slide plate, wherein two first slide plates are provided and are perpendicular to the cross bar, both ends of the first slide plate are respectively sleeved on the two cross bars, the two cross bars are respectively fixedly connected to one end of the two first slide plates, the first slide plate is provided with a first arc segment and a first convex block, a puncturing head is extended from the center of the first arc segment, and a first inclined surface is provided on the first convex block;

[0029] A second slide plate, wherein two of the second slide plates are provided and are perpendicular to the first slide plate, each of the second slide plates is provided with a clearance groove at both ends, the first slide plate passes through the clearance groove so that the second slide plate is slidably arranged at both ends of the first slide plate, the second slide plate is provided with a second arc segment and a first notch, a piercing head extends from the center of the shape of the second arc segment, the shape of the first notch matches the shape of the first convex block, and the first notch is provided with a second inclined surface that is in contact with the first inclined surface, and the first arc segments and the second arc segments of all the first slide plates and the second slide plates can be assembled into a complete circle;

[0030] A crushing power assembly, wherein the crushing power assembly is used for moving the first slide plate and the second slide plate so that the first arc segments and the second arc segments of all the first slide plates and the second slide plates can enclose a complete circle coaxial with the squeeze screw at the outer periphery of the squeeze screw so that the piercing head pierces and crushes the tea residue discharged from the discharge port of the explosion shell;

[0031] A reset component is used to reset the first slide plate and the second slide plate.

[0032] Furthermore, the crushing power assembly includes:

[0033] A rack, the rack being fixedly arranged on a side of the cross bar facing the second slide plate;

[0034] The gear ring is fixedly connected to the outer periphery of the squeezing screw and close to the fixed plate. There are only two sections of transmission teeth on the outer periphery of the gear ring. The two sections of transmission teeth are 180 degrees to each other on the outer peripheral surface of the gear ring. The transmission teeth can mesh with the rack.

[0035] In the present technical scheme, the pressing screw rotates circumferentially during the oil pressing process, driving the gear ring to rotate. When the transmission teeth of the gear ring rotate to a state of meshing with the rack, it will move with the rack and the cross bar, forming a state of the two cross bars moving in opposite directions, which will drive the two first slides to approach each other, and the first inclined surface will squeeze the second inclined surface to make the two second slides approach each other along the length direction of the first slide. Then, the first arc segments and the second arc segments of all the first slides and the second slides gradually move toward the axis of the pressing screw and finally form a complete circle. In this process, the piercing head will break the tea residues discharged from the discharge port of the explosion shell toward the pressing screw and will also penetrate the tea residues, further crushing the tea residues. At the same time, the pressing screw is still rotating. If there are still tea residues that have not been broken at this time, they will rotate with the pressing screw. At the same time, the tea residues are pierced or pressed by the piercing head, and the tea residues will receive torsional force and can also be crushed. The tea residues are crushed by the above three effects, and the crushing degree and efficiency are both good.

[0036] Furthermore, the reset assembly is two reset springs, both ends of which are fixedly connected to the two second slides respectively, and the reset springs always have a movement tendency to move the two second slides away from each other so that the first arc and the second arc are both located outside the discharge port of the burst shell.

[0037] Furthermore, a cutting block is provided at one end of the first slide plate and the second slide plate facing the discharge port of the bursting shell, the cutting block is provided with saw teeth, and the cutting block is inclined and the inclination direction is opposite to the rotation direction of the squeezing screw.

[0038] In the present technical scheme, in the latter stage of the process when the first slide plate and the second slide plate approach the pressing screw, tea residues will still be discharged from the discharge port of the bursting shell, and the tea residues will be pushed to the ends of the first slide plate and the second slide plate. The cutting block is inclined and has serrations, and the tea residues are discharged in a spiral shape from the discharge port and will come into contact with the front of the serrations on the cutting block, and the tea residues will be crushed by rubbing against the serrations as they continue to spiral out. At the same time, when the first slide plate and the second slide plate are reset to move away from the pressing screw, the serrations will also crush the tea residues that are spirally rotated, which can prevent the generation of too large pieces of tea residues at the ends when the first slide plate and the second slide plate are approaching the pressing screw for crushing.

[0039] Furthermore, the inner surface of the second arc segment on the second slide plate is inclined from the middle to both sides.

[0040] In the technical solution, the inner ring surface of the second arc segment on the second slide plate is inclined from the middle to both sides to facilitate the crushed tea residues to fall from the second arc segment.

[0041] The beneficial effects of the present invention are:

[0042] 1. The crushing component can be set to crush the tea residue, so that the tea residue can fall smoothly into the material frame below the discharge port, and after crushing, it becomes small-volume fragments, which will not occupy too much space and increase the residue receiving capacity of the material frame.

[0043] 2. The screw rotates circumferentially during the oil pressing process, driving the gear ring to rotate. When the transmission teeth of the gear ring rotate to a state of meshing with the rack, it will move with the rack and the cross bar, forming a state of the two cross bars moving in opposite directions, which will drive the two first slides to approach each other, and the first inclined surface will squeeze the second inclined surface to make the two second slides approach each other along the length direction of the first slide. Then, the first arc segments and the second arc segments of all the first slides and the second slides gradually move toward the axis of the screw and finally form a complete circle. In this process, the piercing head will break the tea residue discharged from the discharge port of the explosion shell toward the screw and will also penetrate the tea residue, further crushing the tea residue. At the same time, the screw is still rotating. If there is still tea residue that has not been broken at this time, it will rotate with the screw. At the same time, the tea residue is penetrated or pressed by the piercing head, and the tea residue will receive torsional force and can also be crushed. The tea residue is crushed by the above three effects, and the crushing degree and efficiency are both good.

[0044] 3. Stirring and oil pressing share the same power source, which can save energy.

[0045] 4. In the latter stage of the process when the first and second slide plates approach the squeezing screw, tea residue will still be discharged from the discharge port of the bursting shell, and the tea residue will be pushed to the ends of the first and second slide plates. The cutting block is inclined and has serrations. The tea residue is discharged in a spiral shape from the discharge port and will contact the front of the serrations on the cutting block. The tea residue continues to spiral out and will be crushed by rubbing against the serrations. At the same time, when the first and second slide plates are reset to move away from the squeezing screw, the serrations will also crush the spirally rotated tea residue, which can prevent the generation of too large pieces of tea residue at the ends when the first and second slide plates are approaching the squeezing screw for crushing.

[0046] 5. The inner surface of the second arc segment on the second slide plate is inclined from the middle to both sides to facilitate the crushed tea residue to fall from the second arc segment. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] Embodiment 1

[0068] like Figure 1 As shown, a production process of edible oil comprises:

[0069] S1: Drying: Use a dryer to dry the camellia seeds, set the temperature of the dryer to 60°C, and when the temperature drops by 58°C, the blower of the dryer blows until the temperature reaches 60°C, then the blower stops blowing, so that the furnace temperature of the constant temperature hot air dryer is maintained between 58°C and 60°C to dry the camellia seeds;

[0070] S2: Shelling: a shelling machine shells the camellia seeds, and then the camellia seeds are sent to a mold separator to remove moldy camellia seeds;

[0071] S3: Steaming and frying, using a steaming and frying pan to steam and fry the camellia seeds, the heat transfer oil boiler of the steaming and frying pan controls the temperature of the heat transfer oil to be maintained between 62°C and 65°C through a thermostatic controller, and the steaming and frying time of the steaming and frying pan is 30-35 minutes;

[0072] S4: pressing, using a screw oil press 1 to press the camellia seeds to obtain raw camellia oil, and the screw oil press 1 can crush the residue;

[0073] S5: Filtration and refining: The crude oil initially obtained needs to be coarsely filtered and finely filtered to remove solid particles and some impurities. Subsequently, degumming, deacidification and other refining processes may be required to obtain edible camellia oil.

[0074] The tea dregs are broken into pieces so that they can smoothly fall into the material frame 12 below the discharge port 10 , and after being broken into pieces of small size, they will not occupy too much space, thereby increasing the dregs receiving capacity of the material frame 12 .

[0075] Embodiment 2

[0076] like Figure 2-5 As shown, the screw oil press 1 includes a frame 2, on which a bursting shell 3, a feed hopper 4 and an oil receiving pan 5 are arranged. The bursting shell 3 is fixedly arranged on the frame 2, and a plurality of pressing rings 6 with end faces fitting are fixedly arranged in the bursting shell 3, and an oil outlet groove is opened on the pressing ring 6, and a pressing screw 7 is passed through the bursting shell 3, and the pressing screw 7 and the pressing ring 6 are coaxially arranged in the inner ring of the pressing ring 6, and there is a gap between the outer periphery of the pressing screw 7 and the inner ring of the pressing ring 6, and the thread depth of the pressing screw 7 gradually becomes shallower along the feed port 9 to the discharge port 10 of the bursting shell 3, and the pressing screw 7 is connected to the oil pressing power component and can rotate circumferentially, and the feed port 9 of the bursting shell 3 is provided with a crushing component 8, and the crushing component 8 is used to crush the tea residues discharged from the inlet and outlet of the bursting shell 3; the feed hopper 4 is arranged above the feed port 9 of the bursting shell 3, and the feed hopper 4 is provided with a stirring component 11, which is used to make the tea seeds in the feed hopper 4 fall into the bursting shell 3; the bottom of the bursting shell 3 is open, and the oil receiving pan 5 is arranged below the bursting shell 3, and the oil receiving pan 5 is used to receive the tea oil flowing out of the oil outlet groove of the pressing ring 6.

The tea seeds that fall into the transmission of the pressing screw 7 move toward the discharge port 10 of the explosion shell 3. Since the thread depth of the pressing screw 7 gradually becomes shallower along the feed port 9 to the discharge port 10 of the explosion shell 3, the tea seeds will be squeezed out of the tea oil due to the reduction of space. The tea oil flows out of the oil groove on the pressing ring 6 to the oil receiving tray 5, and the tea residue is flattened and discharged from the discharge port 10 of the explosion shell 3. However, the tea residue is discharged from the outlet end in a continuous sheet shape. The volume is too large to easily fall into the discharge port 10 below, and it is easy to accumulate too much and escape from the top, forming a Figure 2-3 Moreover, the discharge volume from the lower discharge port 10 is large, which will occupy too much space, so that the collection frame 12 can only hold a small amount of residue before it is full. The crushing component 8 can crush the tea residue, so that the tea residue can smoothly fall into the material frame 12 below the discharge port 10, and after crushing, it becomes small-volume fragments, which will not occupy too much space, and increase the residue receiving capacity of the material frame 12.

[0081] Start the oil pressing motor 13 to rotate the transmission shaft 15, drive the screw 7 to rotate and press the oil, and at the same time, the second flywheel 23 rotates to drive the first flywheel 21 to rotate, so that the conversion shaft 18 and the second bevel gear 22 rotate, so that the first bevel gear 20 rotates with the stirring shaft 17 and the tea-push rod 19, so as to achieve the stirring of the tea seeds in the feed hopper 4, promote the tea seeds to fall into the explosion shell 3 better, and it is not easy to cause material blockage. The stirring and oil pressing share the power source, which can save energy. The stirring shaft 17 extends below the explosion shell 3 and is provided with an auger. The auger can promote the tea seeds to fall evenly onto the screw 7.

[0082] Embodiment 4

[0083] like Figure 5-12As shown, the crushing assembly 8 includes a fixed plate 25, a first slide plate 26, a second slide plate 27, a crushing power assembly and a reset assembly. The fixed plate 25 is fixedly arranged on the frame 2 near the discharge port 10 of the burst shell 3. Two sets of opposite brackets 28 are arranged on the fixed plate 25, and a cross bar 29 is slidably arranged on each set of brackets 28; there are two first slide plates 26, both of which are perpendicular to the cross bars 29, and both ends of the first slide plate 26 are respectively sleeved on the two cross bars 29, and the two cross bars 29 are respectively fixedly connected to one end of the two first slide plates 26, and the first slide plate 26 is provided with a first arc segment 30 and a first protrusion 31, and a piercing head 32 extends from the center of the shape of the first arc segment 30, and a first inclined surface 33 is arranged on the first protrusion 31; there are two second slide plates 27, both of which are perpendicular to the first slide plate 26, and each second slide plate 27 has a clearance groove 34 at both ends, and the first slide plate 26 passes through the clearance groove 34 to allow the second slide plate 27 to slide and be arranged on the first slide plate 26. At both ends of a slide plate 26, a second slide plate 27 is provided with a second arc segment 35 and a first notch 36, a piercing head 32 extends from the center of the shape of the second arc segment 35, the shape of the first notch 36 matches the shape of the first protrusion 31, and a second inclined surface 37 is provided on the first notch 36 to be in contact with the first inclined surface 33, and the first arc segments 30 and the second arc segments 35 of all the first slide plates 26 and the second slide plates 27 can be assembled into a complete circle; the crushing power assembly is used for moving the first slide plate 26 and the second slide plate 27 so that the first arc segments 30 and the second arc segments 35 of all the first slide plates 26 and the second slide plates 27 can be enclosed into a complete circle coaxial with the squeeze screw 7 on the outer periphery of the squeeze screw 7 so that the piercing head 32 pierces and crushes the tea residues discharged from the discharge port 10 of the bursting shell 3; the reset assembly is used to reset the first slide plate 26 and the second slide plate 27.

[0084] The crushing power assembly includes a rack 38 and a gear ring 39. The rack 38 is fixedly arranged on the side of the cross bar 29 facing the second slide plate 27; the gear ring 39 is fixedly connected to the outer periphery of the squeezing screw 7 and close to the fixed plate 25. The outer periphery of the gear ring 39 has only two sections of transmission teeth 41, and the two sections of transmission teeth 41 are 180 degrees to each other on the outer peripheral surface of the gear ring 39. The transmission teeth 41 can mesh with the rack 38.

[0085] The screw 7 rotates circumferentially during the oil pressing process, driving the gear ring 39 to rotate. When the transmission tooth 41 of the gear ring 39 rotates to a state of meshing with the rack 38, it will move the rack 38 and the cross bar 29, forming a state where the two cross bars 29 move in opposite directions, and then drive the two first slides 26 to approach each other, and the first inclined surface 33 will squeeze the second inclined surface 37 to make the two second slides 27 approach each other along the length direction of the first slide 26, so that all the first slides 26 and the second slides 27 have first arc segments 30 and second arc segments 31. The segment 35 gradually moves axially toward the squeezing screw 7 and finally forms a complete circle. During this process, the piercing head 32 will break the tea residue discharged from the discharge port 10 of the bursting shell 3 toward the squeezing screw 7 and penetrate the tea residue to further crush the tea residue. At the same time, the squeezing screw 7 is still rotating. If there is still tea residue that has not been broken, it will rotate with the squeezing screw 7. At the same time, the tea residue is penetrated or pressed by the piercing head 32, and the tea residue will receive torsional force and can be crushed. The tea residue is crushed by the above three effects, and the crushing degree and efficiency are both good.

[0086] The reset assembly is two reset springs 40, both ends of which are fixedly connected to the two second slides 27 respectively. The reset spring 40 always has a movement tendency to move the two second slides 27 away from each other so that the first arc and the second arc are both located outside the discharge port 10 of the bursting shell 3.

[0087] The first slide plate 26 and the second slide plate 27 are both provided with a cutting block 42 at one end facing the discharge port 10 of the bursting shell 3, and the cutting block 42 is provided with a sawtooth 43. The cutting block 42 is tilted and the tilting direction is opposite to the rotation direction of the squeezing screw 7. In the later stage of the process of the first slide plate 26 and the second slide plate 27 approaching the squeezing screw 7, tea residues will still be discharged from the discharge port 10 of the bursting shell 3, and the tea residues will be pushed to the ends of the first slide plate 26 and the second slide plate 27. The cutting block 42 is tilted and has sawtooth 43. The tea residues are discharged from the discharge port 10 in a spiral shape and will contact the sawtooth 43 on the cutting block 42. The tea residues continue to spiral out and will be crushed by rubbing against the sawtooth 43. At the same time, when the first slide plate 26 and the second slide plate are moved in the direction away from the squeezing screw 7, the sawtooth 43 will also crush the tea residues spirally rotated, which can prevent the first slide plate 26 and the second slide plate 27 from generating too large pieces of tea residues at the ends in the process of crushing when approaching the squeezing screw 7.

[0088] like Fig.13 As shown, the inner ring surface 44 of the second arc segment 35 on the second slide plate 27 is inclined from the middle to both sides, which can facilitate the crushed tea residue to fall from the second arc segment 35.
