Description

Technical Field

[0001] The invention relates to the field of vegetable oil pressing, in particular to a pretreatment pressing process of vegetable oil raw materials. Background Art

[0002] Oil pressing is a method of extracting oil by squeezing oil out of oilseeds with the help of mechanical force. According to the depth of the oil pressing and the amount of pressure on the material during pressing, oil pressing can be divided into primary pressing and pre-pressing combined with leaching oil extraction. Compared with other oil extraction methods, oil pressing has the advantages of simple process, less supporting equipment, strong adaptability to oil varieties, flexible production, good oil quality, light color, and pure flavor.

[0003] In the related art, the edible oil production method is divided into two types: pressing (physical) and leaching (chemical). The pressing method is to separate the oil directly from the oil by physical pressure. There is no chemical additive in the whole process, which ensures that the product is safe, hygienic, pollution-free, and the natural nutrition is not destroyed. The pressing is specifically divided into cold pressing and hot pressing. Before cold pressing, the material needs to be crushed and then kept under pressure for a long time (generally about 10 hours or even longer). Before hot pressing, the material also needs to be crushed, fried, steamed, etc., and then kept under pressure for a long time (generally about 10 hours or even longer). However, in the related art, the traditional pressing method, whether it is cold pressing or hot pressing, requires the material to be pressed. The material is subjected to long-term pressure-maintaining treatment, which causes the oil to be in contact with the air for a long time, causing the oil to oxidize and deteriorate. The oil has a certain temperature when it is just pressed. High temperature will accelerate the oxidation rate of the oil, and even produce harmful oxidation products, such as free radicals and peroxides. The remaining residue will affect its nutritional value and taste under long-term pressure-maintaining state, and thus affect its market value. The residue produced after the pressing of plant raw materials is the main raw material for making livestock and poultry feed, and can also be used to make pastry food, health food, cosmetics and antibiotic raw materials. In aquaculture, the various amino acids contained in the residue can fully meet the special needs of fish for amino acids.

[0004] Therefore, it is necessary to provide a pretreatment and pressing process for vegetable oil raw materials to solve the above technical problems. Summary of the invention

[0085] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0086] The invention provides a pretreatment and pressing process for vegetable oil raw materials.

[0087] First embodiment:

[0088] See also Figure 1 to Figure 2 , a pretreatment and pressing process of vegetable oil raw materials, comprising the following steps:

[0089] S1: Raw material pretreatment

[0090] S11. Raw material screening:

[0091] Remove impurities and substandard soybeans from soybeans through screening and sorting;

[0092] S12, soybean cleaning:

[0093] The soybeans are washed with clean water. During the washing process, the soybeans need to be fully stirred and the soybeans floating on the water surface need to be removed;

[0094] S13. Drying or airing soybeans:

[0095] The soybeans are processed by drying machinery or natural drying. When natural drying is used, a breathable plastic net needs to be laid on the ground in advance so that the contact surface between the soybeans and the ground can fully breathe, and then the soybeans are turned over and dried in time according to the intensity of sunlight;

[0096] S14. Soybean Inspection:

[0097] Observe the fullness of soybean particles with the naked eye, and the full soybean particles are qualified.

[0098] The impurity content of soybeans is tested by screening, and those with impurity content less than 0.1% are qualified;

[0099] The moisture content of soybeans is tested by moisture testing instruments, and the moisture content is qualified when it is between 8-10%;

[0100] S2: Raw material pressing

[0101] S21, Raw material loading:

[0102] The barrel assembly 7 is placed on the flip assembly 2 on the loading and unloading workbench 1 by means of a ceiling hanging, the barrel assembly 7 is placed in a vertical state by the flip assembly 2, and then the loading and unloading assembly 3 is used to load the barrel assembly 7;

[0103] Furthermore, during the process of loading the raw materials, if the staff finds impurities in the raw materials, they need to pick them out in time to prevent the impurities from affecting the quality of the crude oil. When the barrel assembly 7 is in a vertical state by turning the assembly 2, the staff needs to stay away from the device and comply with safety operating specifications.

[0104] S22, Raw material pressing:

[0105] The barrel assembly 7 filled with raw materials is transported to the pressing assembly 5 by means of an overhead crane, and the raw materials in the barrel assembly 7 are pressed by the pressing assembly 5;

[0106] Furthermore, after the barrel assembly 7 filled with raw materials is transported to the pressing assembly 5 by means of an overhead crane, the staff needs to pay attention to the horizontal state of the barrel assembly 7. Oil pressing can only be carried out when the barrel assembly 7 is in a horizontal state. After the pressed oil is collected, it needs to be filtered in time to remove impurities in the oil so that the oil is in a clear and transparent state.

[0107] S23, unloading of residual materials:

[0108] The barrel assembly 7 after the squeezing work is completed is transported to the flip assembly 2 by means of a ceiling crane, the barrel assembly 7 is placed in a vertical state by the flip assembly 2, and then the barrel assembly 7 is unloaded by the loading and unloading assembly 3;

[0109] Furthermore, during the pressing process, workers need to wear gloves and operate in a standardized manner. The surface of the ejected residual material has a certain temperature and they need to avoid burns. When unloading the residual material, workers need to stay away. If they need to avoid operation, they need to shut down the machine in time to avoid safety accidents.

[0110] S24, Residue Crushing:

[0111] In the process of unloading the residual materials, the residual materials are pulverized by the waste crushing component 4, the waste crushing component 4 is driven by the adjusting component 8 to reciprocate and evenly unload the materials, and the unloaded residual materials are screened by the screening component 9;

[0112] Furthermore, when the waste crushing component 4 is working, the staff must not put their hands into the device to operate it. If operation is required, the device must be shut down. After the residual materials are crushed, the heat dissipation speed of the residual materials can be effectively accelerated to avoid overheating of the residual materials causing internal heat accumulation, thereby causing the residual materials to deteriorate and be damaged.

[0113] When screening soybeans, a 12-mesh / inch screen is used to screen the soybeans, and the impurity content is less than 0.1% after screening;

[0114] When washing soybeans, water and soybeans are mixed in a ratio of 1:0.2-0.4, the washing temperature is controlled at 15-35 degrees Celsius, and the washing time is 40-80 seconds;

[0115] When drying or airing soybeans, mechanical drying requires drying until the moisture content is less than 10%, while airing requires controlling the moisture content at 8-10%.

[0127] The pretreatment pressing process step S22 requires the use of a pressing component 5 when pressing the soybeans;

[0128] A pressing assembly 5, the pressing assembly 5 comprising a horizontal hydraulic press 51, a pressing head 52 is arranged on the left side of the inner side of the horizontal hydraulic press 51, a barrel oil pressing support 53 is arranged on the inner side of the horizontal hydraulic press 51, and oil receiving grooves 54 are arranged on the front and rear sides of the top of the barrel oil pressing support 53;

[0129] Please combine Figure 2 , Fig.11 and Fig.12 : The horizontal hydraulic press 51 is a 1000T hydraulic press. By extending the horizontal hydraulic press 51, the pressure head 52 can be driven to press the raw materials in the barrel assembly 7. The crude oil produced after squeezing will be collected through the oil receiving groove 54, and the barrel oil pressing bracket 53 is used to support the barrel assembly 7.

[0132] The pretreatment pressing process step S24 requires the use of a waste crushing component 4, a regulating component 8 and a screening component 9 when crushing the soybean residue;

[0133] A waste crushing assembly 4, the waste crushing assembly 4 includes a waste storage box 41 arranged at the rear side of the loading and unloading workbench 1 and located on the left side of the vacuum loader 311, the inner side of the waste storage box 41 is connected to two connecting brackets 42 by bolts, a crushing cover 43 is arranged on the opposite side of the two connecting brackets 42, the top of the crushing cover 43 is connected to a feed hopper 44, the inner side of the feed hopper 44 is provided with a buffer pad 45, the front side of the bottom of the crushing cover 43 is provided with a moving brush 46, the inner side of the crushing cover 43 is provided with a rotating roller 47 for horizontal rotation, the surface of the rotating roller 47 is provided with a crushing knife group 48, and the right side of the crushing cover 43 is provided with a first motor 49, and the output end of the first motor 49 is fixedly connected to the right end of the rotating roller 47;

The connecting bracket 42 can be fixed to the waste storage box 41 by bolts, so as to facilitate the installation and disassembly of the waste crushing assembly 4. When the residue produced after squeezing is crushed, the residue will fall on the feed hopper 44. The setting of the buffer pad 45 can buffer the impact force when the residue falls, and prevent the residue from scattering outside. The feed hopper 44 is designed to be inclined. The residue falling on the feed hopper 44 will be affected by gravity and the vibration generated by the first motor 49, the rotating roller 47 and the crushing knife group 48 when they are working, so as to fall into the crushing cover 43. The first motor 49 is a three-phase asynchronous motor. The rotation of the first motor 49 drives the rotating roller 47 and the crushing knife group 48 to crush the residue.

[0135] An adjusting component 8, wherein the adjusting component 8 comprises two bidirectional threaded screws 81 which are longitudinally rotatably arranged on the inner side of the waste storage box 41, the surfaces of the two bidirectional threaded screws 81 are threadedly arranged with screw blocks 82, the surfaces of the two screw blocks 82 are slidably connected to the inner side of the waste storage box 41, two mounting brackets 83 are arranged on the rear side of the waste storage box 41, the tops of the two mounting brackets 83 are arranged with second motors 84, the output ends of the two second motors 84 are respectively fixedly connected to the rear ends of the two bidirectional threaded screws 81, the two connecting brackets 42 are respectively inserted into the inner sides of the two screw blocks 82 and fixedly connected by bolts, the inner sides of the two screw blocks 82 are respectively provided with grooves for use with the two connecting brackets 42, and the inner side of the waste storage box 41 is provided with grooves for use with the connecting brackets 42;

[0136] Please combine Figures 16 to 18 : The inner side of the screw block 82 is provided with a thread used in conjunction with the bidirectional threaded screw rod 81, and the screw block 82 can be driven to move forward and backward by the rotation of the bidirectional threaded screw rod 81. A groove used in conjunction with the screw block 82 is provided in the waste storage box 41, which can provide the screw block 82 with forward and backward sliding. The second motor 84 is a three-phase asynchronous motor and is externally connected to a power supply;

[0137] Please combine Fig.18 and Fig.19 : Through the grooves opened on the two screw blocks 82, the screw blocks 82 and the connecting bracket 42 can be connected by bolts. After the connection, the movement of the screw blocks 82 can drive the waste crushing assembly 4 to move forward and backward. The groove opened in the waste storage box 41 for the connecting bracket 42 can provide stability when the connecting bracket 42 moves, so that the waste crushing assembly 4 can be in a stable state when moving forward and backward.

[0138] A screening component 9, the screening component 9 comprises a screening plate 91 arranged on the inner side of the waste storage box 41 and located at the bottom of the adjusting component 8, six guide rods 92 are slidably arranged on the inner side of the screening plate 91, both ends of the six guide rods 92 are fixedly connected to the inner side of the waste storage box 41, a first spring 93 is sleeved on the surface of the six guide rods 92 and located at the bottom of the screening plate 91, a limiting ring 94 is arranged on the surface of the six guide rods 92 and located at the top of the screening plate 91, convex plates 95 are arranged on both sides of the top of the screening plate 91, movable brackets 96 are arranged on both sides of the two screw blocks 82, and a protective frame 97 is arranged on the top of the screening plate 91;

[0139] Please combine Fig. 20 and Fig.21 : The inner side of the screening plate 91 is provided with a groove for use with the guide rod 92, which can slide up and down on the surface of the guide rod 92. The convex plate 95 and the movable bracket 96 are used in relative cooperation. When the movable bracket 96 moves to the convex part of the convex plate 95, the convex plate 95 will drive the screening plate 91 to move downward. When the movable bracket 96 moves to the concave part of the convex plate 95, under the action of the first spring 93, the screening plate 91 will move upward. When the screening plate 91 reciprocates up and down, the crushed residue can be screened to prevent larger particles of residue from entering the waste storage box 41. This structure can improve the uniformity of the particle size of the crushed residue on the one hand, and improve the heat dissipation effect of the crushed residue on the other hand (because the heat contained in the larger particles of residue is not easy to dissipate, and mixing in the smaller particles of residue will cause local heating of the residue, which is easy to cause local deterioration of the residue particles).

[0140] An adjusting plate 98 is slidably provided on the inner side of the screening plate 91, two blocking plates 99 are vertically provided on the rear side of the top of the adjusting plate 98, contact pads 910 are provided on the front sides of the two blocking plates 99, adjusting guide rods 911 are slidably provided on the inner sides of the two blocking plates 99, threaded sleeves 912 are threadedly connected on the surfaces of the two adjusting guide rods 911 and located on the front sides of the two blocking plates 99, second springs 913 are sleeved on the surfaces of the two adjusting guide rods 911 and located on the rear sides of the two blocking plates 99, sliders 914 are provided on the rear ends of the two adjusting guide rods 911, and the two sliders 914 are slidably connected to the inner side of the waste storage box 41;

[0141] Please combine Figure 22 to Figure 25: The inner side of the screening plate 91 is provided with a groove used in conjunction with the adjustment plate 98, so that the adjustment plate 98 can slide back and forth on the inner side thereof. The adjustment plate 98 is provided with a hole of the same size as the screening plate 91 for screening the crushed residue. The inner side of the blocking plate 99 is provided with a groove used in conjunction with the adjustment guide rod 911, so that the blocking plate 99 can slide on the surface of the adjustment guide rod 911. The surface of the adjustment guide rod 911 is partially provided with threads used in conjunction with the threaded sleeve 912, so that the threaded sleeve 912 can rotate back and forth on its surface;

[0142] Please combine Fig. 20 , Fig. 22 and Fig.23 : A groove is provided on the inner side of the waste storage box 41 for use with two sliders 914, which can allow the sliders 914 to slide up and down inside. When the screening plate 91 moves up and down for screening, the sliders 914 will follow the screening plate 91 to slide up and down in the waste storage box 41.

[0143] When the residual material is crushed in S24, the first motor 49 is turned on, and the rotating roller 47 and the crushing knife group 48 are used to crush the residual material. During the crushing process, the second motor 84 is turned on, and the two-way threaded screw 81 and the screw block 82 are used to drive the crushing cover 43 to move back and forth, so that the crushed residual material falls evenly. During the movement of the screw block 82, the falling residual material can be screened by the screening plate 91.

[0144] In this embodiment: after the oil pressing barrel body 71 is loaded by the turning assembly 2 and the loading and unloading assembly 3, the oil pressing barrel body 71 can be transferred to the pressing assembly 5 by means of a ceiling hanging method, and the raw materials are pressed by the pressing assembly 5. During the pressing process of the raw materials in the oil pressing barrel body 71 being continuously pressurized and maintained by the pressing assembly 5, the barrel assembly 7 on the barrel OEM bracket 6 can be moved to the oil cylinder turning bracket 24 by means of a ceiling hanging method, and loaded by the turning assembly 2 and the loading and unloading assembly 3. After loading, it is moved back to the barrel OEM bracket 6, so that the barrel assembly 7 can be loaded by using the time of pressing the raw materials;

[0145] After the pressing component 5 has finished pressing the raw material, the barrel component 7 is moved to the flip component 2 by using the overhead crane, and then the residual material produced after the pressing of the raw material is unloaded by the loading and unloading component 3, and the residual material is crushed by the waste crushing component 4. After the residual material is unloaded, the loading and unloading component 3 can be used to reload the barrel component 7. At the same time, the barrel component 7 loaded with raw materials on the barrel OEM bracket 6 can be moved to the pressing component 5 by using the overhead crane, and it is squeezed by the pressing component 5, so that the device can work in a cycle, so that time can be fully utilized and the oil pressing efficiency of the device can be greatly improved.

[0146] When the second motor 84 is started, the combination design of the screw block 82 and the connecting bracket 42 can make the waste crushing assembly 4 move during the crushing process, thereby avoiding the local accumulation of the crushed residues, without the need for manual leveling, and the crushed residues can be better cooled during the movement and falling process, which is conducive to improving the heat dissipation effect of the crushed residues;

[0147] Moreover, after the waste crushing component 4 and the adjusting component 8 are used in conjunction, two working modes can be generated. The first mode is: when the residue generated after the raw material is squeezed and pushed into the feed hopper 44, the waste crushing component 4 and the adjusting component 8 are started to crush the residue. When the residue in the crushing cover 43 is crushed, the waste crushing component 4 is located at the material receiving position through the adjusting component 8, and then the second cylinder 38 and the discharge plate 39 are used to push the residue into the feed hopper 44, and then the above operation is repeated. When working in this mode, the adjusting component 8 needs to be stopped. The second mode is to adjust the pushing time interval of the second cylinder 38, so that when the adjusting component 8 and the waste crushing component 4 have reciprocated for many times and the feed hopper 44 is located at the material receiving position, the second cylinder 38 is opened at this moment so that the discharge plate 39 pushes the residue into the feed hopper 44, and the adjusting component 8 is not stopped in the middle process. This mode enables the adjusting component 8, the waste crushing component 4 and the second cylinder 38 to form a working cycle, thereby improving the crushing efficiency of the residue.

[0148] When the screw block 82 is driven to move by the rotation of the bidirectional threaded screw 81, the movable bracket 96 can be driven to move. With the cooperation of the movable bracket 96 and the convex plate 95, the screening plate 91 can be reciprocated up and down, so that the crushed residue can be screened.

[0149] Furthermore, when the bidirectional threaded screw 81 and the screw block 82 drive the crushing cover 43 to move backward to a certain position through the connecting bracket 42, the crushing cover 43 is squeezed to drive the two blocking plates 99 to move backward, so that the blocking plate 99 slides backward on the surface of the adjustment guide rod 911, and the second spring 913 contracts, and the adjustment plate 98 is driven to slide on the inner side of the screening plate 91 through the movement of the blocking plate 99. When the adjustment plate 98 slides to a certain position, the screening plate 91 can be sealed, thereby preventing impurities from falling into the waste storage box 41 when the crushed residue is transported, so that the crushed residue can be protected.

[0150] The two threaded sleeves 912 are rotated backward on the two adjustment guide rods 911 respectively, so that the positions of the blocking plate 99 and the adjustment plate 98 can be adjusted, and then the size of the pores of the screening plate 91 when in use can be adjusted to meet the crushing requirements of different types of residual materials.

[0151] Please refer to Figures 1 to 25 The working principle of the pretreatment and pressing process of vegetable oil raw materials provided by the present invention is as follows:

[0152] Step S1, control the two first cylinders 210 to extend, through the extension of the two first cylinders 210, under the action of the two connecting frames 211, the two unloading guide plates 213 can be moved to the separated side along the two groups of limit guide plates 212 until the two unloading guide plates 213 are fully opened, and then the barrel assembly 7 is placed on the horizontally placed cylinder flip bracket 24 by means of a ceiling hanging method, and the barrel assembly 7 is fixed by the electromagnet suction cup 27, and then the flip cylinder 22 is started, and the cylinder flip bracket 24 is driven to rotate upward with the two vertical ball bearings 25 as the center point by the extension of the flip cylinder 22, so that the cylinder flip bracket 24 and the loading and unloading workbench 1 form a vertical state, and the barrel assembly 7 and the loading and unloading workbench 1 form a vertical state;

[0153] Step S2, open the indexing pin 73 on the top of the oil pressing barrel body 71, take out the end plate 72 and the oil filter plate 74 in the oil pressing barrel body 71 in turn through the cross truss 35 and the electromagnet fixing plate 36, and place them on the partition storage rack 37, then start the vacuum feeder 311, transport the raw materials in the raw material storage box 33 to the hopper 32 through the pipeline, open the solenoid valve provided on the hopper 32, and thus feed the oil pressing barrel body 71. During the feeding process, the oil filter plate 74 and the end plate 72 are installed back into the oil pressing barrel body 71 in turn through the cross truss 35 and the electromagnet fixing plate 36 until the feeding is completed, close the indexing pin 73 on the top, and after the feeding is completed, the oil cylinder 22 is retracted to make the oil cylinder flip bracket 24 and the barrel assembly 7 parallel to the loading and unloading workbench 1;

[0154] Step S3, transport the barrel assembly 7 that has been loaded to the barrel oil pressing support 53 by means of an overhead crane, start the horizontal hydraulic press 51, and pause when the horizontal hydraulic press 51 drives the pressure head 52 to contact the end plate 72, adjust the indexing pin 73 to cancel the connection with the end plate 72 on the contact side of the pressure head 52, and then start the horizontal hydraulic press 51 to pressurize and maintain the raw materials in the barrel assembly 7, and collect the squeezed crude oil through the oil receiving tank 54;

[0155] Step S4, during the process of the pressing component 5 continuously pressurizing and maintaining the raw materials in the oil pressing barrel body 71, the barrel component 7 on the barrel OEM support 6 can be moved to the cylinder flip bracket 24 by means of a ceiling hanging method, and the barrel component 7 is loaded by the flip component 2 and the loading and unloading component 3 (the loading steps can refer to steps S1 and S2), and after the loading is completed, it is moved back to the barrel OEM support 6;

[0156] Step S5, when the pressing assembly 5 completes the pressing of the raw material, the barrel assembly 7 is moved to the cylinder flip bracket 24 by using the overhead crane, and the flip assembly 2 is used to make it vertical to the loading and unloading workbench 1 (refer to step S1), and then the two first cylinders 210 are controlled to retract, so that the two unloading guide plates 213 move to the opposite side until the two unloading guide plates 213 contact each other to form a surrounding state for the oil pressing barrel body 71, at this time, all the indexing pins 73 are opened, and the end plate 72, the oil filter plate 74 and the residual material produced after pressing are pushed upward by the ejection cylinder 310, and at the same time, the cross truss 35 and the electromagnet are used to fix The fixed plate 36 removes the end plate 72 and the internal oil filter plate 74 in turn, and places them on the partition storage rack 37, and at the same time opens the second cylinder 38, and the second cylinder 38 uses the discharge plate 39 to push the raw materials produced after pressing backward on the discharge guide plate 213, and the pushed-down residual materials will fall on the feed hopper 44 under the influence of gravity, and then fall into the crushing cover 43 from the feed hopper 44, and turn on the first motor 49, and the rotation of the first motor 49 drives the rotating roller 47 and the crushing knife group 48 to crush the residual materials. After the discharge of the residual materials is completed, the oil pressing barrel body 71 can be directly loaded (refer to step S2);

[0157] Step S6, in the process of unloading, crushing and reloading the residual material after squeezing, the barrel assembly 7 loaded with raw materials on the barrel OEM support 6 can be moved to the squeezing assembly 5 by means of an overhead hanging method, and the raw materials are squeezed by the squeezing assembly 5;

[0158] Step S7, while the waste crushing assembly 4 is crushing the squeezed residue, the second motor 84 is turned on, and the rotation of the second motor 84 drives the bidirectional threaded screw 81 to rotate, and the rotation of the bidirectional threaded screw 81 drives the screw block 82 to move forward and backward, and the front and rear movement of the two screw blocks 82 drives the waste crushing assembly 4 to move forward and backward by using the connecting bracket 42, so that the crushed residue is evenly scattered in the waste storage box 41. When the adjustment assembly 8 cooperates with the waste crushing assembly 4 to crush, it can adopt a shutdown or non-stop working mode according to the use requirements;

[0159] Step S8, when the bidirectional threaded screw 81 and the screw block 82 are working, the movable bracket 96 will work along with the screw block 82. When the movable bracket 96 moves to the convex part of the convex plate 95, the convex plate 95 will drive the screening plate 91 to move downward. When the movable bracket 96 moves to the concave part of the convex plate 95, the screening plate 91 will move upward under the action of the first spring 93, so that the screening plate 91 can reciprocate up and down, and then the crushed residue can be screened.

[0160] Step S9, when the crushing of the residual material after squeezing is completed, the crushing cover 43 is driven to move backward by the screw block 82 and the connecting bracket 42 through the rotation of the bidirectional threaded screw 81. When the crushing cover 43 moves to a certain position, the blocking plate 99 moves backward. The movement of the blocking plate 99 drives the adjustment plate 98 to move backward, so that the screening plate 91 can be sealed, thereby preventing impurities from entering the waste material storage box 41, so as to protect the residual material after crushing;

[0161] Step S10, rotate the two threaded sleeves 912 backward on the two adjustment guide rods 911 respectively, so that the blocking plate 99 drives the adjustment plate 98 to slide backward on the inner side of the screening plate 91, and then the size of the pores of the screening plate 91 can be adjusted when it is used, so as to meet the crushing requirements of different types of residues.
