Description

Technical Field

[0001] The invention relates to edible oil processing, in particular to a camellia seed pretreatment device and a camellia seed pretreatment method using the device. Background Art

[0002] Chinese patent application number 2019200217172 discloses a modular air-energy heat pump stacked tea oil seed drying room, in which a perforated steel plate is set in the drying room as a material table for placing tea oil seed materials to be dried, but this material table is not provided with a material turning mechanism, which easily causes uneven drying of the tea oil seed materials. Therefore, it is necessary to design a material table with a material turning function.

[0003] In addition, Chinese patent application number 2023214000177 discloses a tea seed drying device that can dry tea seeds evenly. The material table adopts a filter frame structure. A continuously rotating cam is arranged under the filter frame. The cam and the outer wall of the reinforcing rod fixedly installed on the bottom surface of the filter frame contact and squeeze each other, so that the entire filter frame moves upward. At the same time, the filter frame can fall downward under the action of its own gravity. In the process of the filter frame moving up and down, the tea seeds accumulated on its upper surface can be turned over by inertia, so that the drying hot air can enter the gap between the tea seeds, thereby improving the drying effect of the device on the tea seeds. Although the existing material table has the function of turning over materials, during the up and down movement of the filter frame, the collision between the cam and the filter frame reinforcement rod, and the collision of the falling tea seeds on the filter frame, cause the operation noise of the entire device to be very loud, and the up and down movement of the filter frame is also likely to cause the tea seeds to scatter, resulting in material loss. Therefore, the existing material table with the material turning function also has disadvantages and does not meet the current environmental protection requirements of edible oil processing enterprises for the production environment. Summary of the invention

[0004] The purpose of the present invention is to propose a camellia seed pretreatment device for turning and homogenizing the camellia seeds during processing; and to propose a camellia seed pretreatment method, which uses the camellia seed pretreatment device to effectively ensure the quality and efficiency of the camellia seed pretreatment, and also has the characteristics of energy saving and environmental protection, and can effectively meet the environmental protection needs of edible oil processing enterprises for the production environment.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] An oil-tea camellia seed pretreatment device, which includes a material table. The material table has a horizontally arranged tabletop and vertical supports located at the four peripheral edges of the tabletop. The tabletop is made of a flexible material and is evenly provided with ventilation holes thereon. It is characterized in that: it further includes a material turning mechanism arranged below the tabletop. On the frame of the material turning mechanism, there are a forward and reverse motor, a lead screw, a slider, a slider guide rail and a roller. The lead screw is horizontally arranged and is located in the middle below the tabletop. The slider is threadedly connected to the lead screw. The output shaft of the forward and reverse motor is coaxially connected to one end of the lead screw. The slider guide rail is located directly below the lead screw and is arranged in the same direction as the lead screw. The slider is movably connected to the slider guide rail and can move horizontally along the slider guide rail. When the output shaft of the forward and reverse motor rotates, it can drive the lead screw to rotate, and then drive the slider to reciprocate along the lead screw.

[0007] A wheel shaft is provided in the middle of the roller. Two rollers are longitudinally arranged and symmetrically arranged on both sides of the top of the slider. One end of the wheel shaft is fixedly connected to the slider. The two ends of the roller are respectively located below the middle of the tabletop and below the edge of the tabletop. The top of the roller is higher than the slider and contacts the tabletop. When the slider moves, it can drive the roller to move synchronously, and at the same time the roller rolls along the tabletop to drive the tabletop to fluctuate.

[0008] Furthermore, a number of protrusions are evenly distributed on the wheel surface of the roller.

[0009] Furthermore, to improve the stability of the roller, the other end of the wheel shaft of the roller is also fixedly connected with an end block. A end block guide wheel is provided at the bottom of the end block. A end block guide rail is horizontally arranged below the end block guide wheel. The end block guide wheel is placed on the end block guide rail so that the end block and the end block guide rail are in rolling contact.

[0010] Furthermore, to improve the smoothness of the slider movement, a slider guide wheel is also provided at the bottom of the slider. The slider guide wheel is placed on the slider guide rail so that the slider and the slider guide rail are in rolling contact.

[0011] Furthermore, to improve the load-bearing capacity of the tabletop, a number of evenly distributed longitudinal support bars are provided on the tabletop.

[0012] The present invention also includes a material weighing mechanism. The material weighing mechanism includes a weighing plate and a weighing device arranged below the weighing plate. The weighing device includes a gravity sensor. The weighing plate has two weighing main board parts symmetrically arranged outside the frame. The vertical support of the material table can be placed on the weighing main board parts so that the material weighing mechanism weighs the material table.

[0013] Further, near both ends of the lead screw of the material turning mechanism, there are respectively provided travel switches, a total of 2 travel switches. The 2 travel switches are respectively electrically connected to the weighing device. The travel switch can be actuated by the collision of the slider; after the travel switch is collided, the weighing device is powered on for weighing; when the slider leaves the travel switch, the weighing device is powered off and stops weighing.

[0014] The present invention further includes an air source heat pump drying device. The air source heat pump drying device includes an air source heat pump dryer and a drying room. The oil-tea camellia seed pretreatment device is arranged in the drying room; on the ground of the drying room, there is provided a weighing device groove. The weighing device of the material weighing mechanism is fixed in the weighing device groove. The weighing plate is flush with the ground of the drying room. The material turning mechanism is fixed to the ground of the drying room by a frame.

[0015] An oil-tea camellia seed pretreatment method uses the oil-tea camellia seed pretreatment device of the present invention to perform drying pretreatment on oil-tea camellia seeds. On the tabletop of the material table, there is laid the oil-tea camellia seed material to be processed. The air source heat pump drying device is started to dry the oil-tea camellia seed material. The oil-tea camellia seed pretreatment device is started. The rollers cause the tabletop of the material table to fluctuate to realize the turning of the oil-tea camellia seed material. The weighing device weighs the material table. Until the weighing result meets the requirements, the drying pretreatment is stopped. The air source heat pump drying device is shut down, and the oil-tea camellia seed pretreatment device is shut down.

[0016] Further, to improve the efficiency of the oil-tea camellia seed pretreatment method, the following settings are also made: Set the initial state of the oil-tea camellia seed pretreatment device as the slider being located at one end of the lead screw and colliding with the travel switch near it; Set the forward rotation time and the reverse rotation time of the forward and reverse rotation motor to be T respectively. The time T is the duration for the slider to move from one end of the lead screw to the other end; Set the pause rotation time t of the forward and reverse rotation motor before starting the forward rotation and starting the reverse rotation. When the forward and reverse rotation motor pauses rotation, the slider is located at one end of the lead screw and collides with the travel switch near it, and the weighing device of the oil-tea camellia seed pretreatment device is powered on for weighing.

[0017] The oil-tea camellia seed pretreatment method realized through the above settings includes the following steps:

[0018] Step 1, the air source heat pump drying device is started to operate, and the oil-tea camellia seed pretreatment device is started to operate. At this time, the slider is located at one end of the lead screw and collides with the travel switch near it. The forward and reverse rotation motor pauses for a time t, and at the same time, the weighing device is powered on to operate and weigh the material table.

[0019] Step 2, after the time t, the forward and reverse rotation motor starts to rotate forward or reverse. After rotating for a time T, the slider moves from one end of the lead screw to the other end of the lead screw. The forward and reverse rotation motor pauses for a time t. At the same time, the slider collides with the travel switch near it, and the weighing device is powered on to operate and weigh the material table again;

[0020] Step 3: Repeat Step 2 until the weighing result meets the requirements, then the air source heat pump drying equipment stops operating, and the oil-tea camellia seed pretreatment device stops operating.

[0021] The present invention has the following outstanding substantive features and remarkable progress:

[0022] 1. The oil-tea camellia seed pretreatment device of the present invention is used for turning and homogenizing during the processing of oil-tea camellia seeds. It integrates a material table, a drying device, a material turning mechanism, and a weighing module. The turning of the material on the flexible table is achieved through the rolling of rollers. This way of turning the material generates very little noise and does not cause the material to scatter, which is very environmentally friendly and can effectively meet the environmental protection requirements of edible oil processing enterprises for the production environment.

[0023] 2. The oil-tea camellia seed pretreatment method of the present invention uses the above-mentioned oil-tea camellia seed pretreatment device. During the drying process, the rollers are activated, and the rolling of the rollers causes the surface of the material table to fluctuate, realizing the uniform turning of the oil-tea camellia seed material, ensuring the effective contact between the oil-tea camellia seed material and the hot air during the drying process; the material table is weighed by a weighing device to monitor the weight change of the oil-tea camellia seeds, so as to monitor the real-time drying effect and ensure that the equipment stops when the required moisture content is reached, thereby efficiently ensuring the quality and efficiency of the oil-tea camellia seed treatment.

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] Embodiment

[0032] ReferenceFigures 1 to 6 , an oil-tea camellia seed pretreatment device, which includes a material table 1. The material table 1 has a horizontally arranged tabletop 11 and vertical brackets 12 located at the four peripheral edges of the tabletop 11. The tabletop 11 is made of a flexible material and is evenly distributed with ventilation holes thereon. The tabletop 11 can be made of a strong cloth material such as non-woven fabric. The cloth material itself has micropores as ventilation holes, or holes with a diameter smaller than that of the oil-tea camellia seeds are opened on the cloth material as ventilation holes. In addition, the material table 1 can adopt a structure with casters at the bottom to facilitate movement.

[0033] Specific reference Figure 6 , a material turning mechanism is provided below the tabletop 11. On the frame 20 of the material turning mechanism, there are a forward and reverse motor 2, a lead screw 3, a slider 4, a slider guide rail 41 and a roller 5. The lead screw 3 is horizontally arranged and is provided in the middle below the tabletop 11. The slider 4 is threadedly connected to the lead screw 3. The output shaft of the forward and reverse motor 2 is coaxially connected to one end of the lead screw 3. The slider guide rail 41 is located directly below the lead screw 3 and is arranged in the same direction as the lead screw 3. The slider 4 is movably connected to the slider guide rail 41 and can move horizontally along the slider guide rail 41. The rotation of the output shaft of the forward and reverse motor 2 can drive the lead screw 3 to rotate, and then drive the slider 4 to reciprocate along the lead screw 3.

[0034] A wheel shaft 50 is provided in the middle of the roller 5. Two rollers 5 are longitudinally arranged and symmetrically arranged on both sides of the top of the slider 4. One end of the wheel shaft 50 is fixedly connected to the slider 4. The two ends of the roller 5 are respectively located below the middle of the tabletop 11 and below the edge of the tabletop 11. The top of the roller 5 is higher than the slider 4 and contacts the tabletop 11. When the slider 4 moves, it can drive the roller 5 to move synchronously. At the same time, the roller 5 rolls along the tabletop 11, thereby driving the tabletop 11 to fluctuate.

[0035] When the above structure is used, the oil-tea camellia seed material to be processed is spread flat on the tabletop 11 of the material table 1, and then the forward and reverse motor 2 is started. The output shaft of the motor drives the lead screw 3 to rotate. Due to the slider 4 threadedly connected to the lead screw 3, the slider 4 reciprocates along the lead screw 3 under the limiting action of the slider guide rail 41. At the same time, the movement of the slider 4 drives the roller 5 connected thereto to move synchronously. The roller 5 rolls along the bottom surface of the tabletop 11, causing the tabletop 11 to fluctuate, so as to realize the turning of the oil-tea camellia seed material.

[0036] It should be noted that the drying process is to accelerate the transfer of moisture in the oil-tea camellia seed material into the air. In this process, it is not necessary to frequently turn the oil-tea camellia seed material. It is only necessary to ensure that after drying for a period of time, the oil-tea camellia seed material can be properly turned over, so as to uniformly and effectively dry the material particles. Therefore, the roller 5 turning structure adopted in this embodiment is very suitable for drying pretreatment, which can not only achieve the turning purpose, but also save energy and protect the environment.

[0037] Further, in this embodiment, a number of protruding portions 51 are evenly distributed on the wheel surface of the roller 5. When the roller 5 rolls, the protruding portions 51 can generate a certain stirring effect on the oil-tea seed material, which helps the uniform distribution and turning of the material. In addition, the gaps between the protruding portions 51 are beneficial to the air circulation below the tabletop 11 during drying as described below, ensuring the drying effect. Another important function of the protruding portions 51 is to reduce the contact area between the roller 5 and the tabletop 11 when the roller 5 rolls, avoiding excessive friction with the tabletop 11 and jamming the roller 5, and thus preventing the situation where the roller 5 is difficult to roll.

[0038] Further, in this embodiment, specifically referring to Figure 2 , the other end of the axle 50 of the roller 5 is fixedly connected to an end block 52. A guide wheel 53 of the end block is provided at the bottom of the end block 52. A guide rail 54 of the end block is horizontally provided below the guide wheel 53 of the end block. The guide wheel 53 of the end block is placed on the guide rail 54 of the end block so that the end block 52 is in rolling contact with the guide rail 54 of the end block. The above structure provides better support for the roller 5 through the end block 52 and the guide wheel 53 of the end block, increasing the structural stability of the roller 5. At the same time, the rolling contact between the end block 52 and the guide rail 54 of the end block is realized through the guide wheel 53 of the end block, reducing the wear between the end block 52 and the guide rail 54 of the end block.

[0039] Further, in this embodiment, a guide wheel of the slider (not shown in the figure) is provided at the bottom of the slider 4. The guide wheel of the slider is placed on the slider guide rail 41 so that the slider 4 is in rolling contact with the slider guide rail 41, reducing the wear between the slider 4 and the slider guide rail 41.

[0040] Further, in this embodiment, specifically referring to Figure 5 , a number of evenly distributed longitudinal support bars 110 are provided on the tabletop 11. The longitudinal support bars 110 can be made of metal materials or wooden materials, and are attached to the top or bottom surface of the tabletop 11. The function of the longitudinal support bars 110 is to provide additional support force, enhance the structural strength of the tabletop 11, and enable the tabletop 11 to withstand greater weight and pressure. In addition, the longitudinal support bars 110 and the roller 5 both adopt the same longitudinal design direction and will not hinder the rolling of the roller 5.

[0041] Further, specifically referring to Figure 6, the oil-tea camellia seed pretreatment device of this embodiment further includes a material weighing mechanism. The material weighing mechanism includes a weighing plate 6 and a weigher 60 disposed below the weighing plate 6. The weigher 60 includes a gravity sensor. The weighing plate 6 has two weighing main board parts 61 symmetrically disposed outside the frame 20. The vertical support 12 of the material table 1 can be placed on the weighing main board parts 61 so that the material weighing mechanism weighs the material table 1. In the above structure, the weighing plate 6 supports the material table 1 by the weighing main board parts 61 and transmits the weight of the material table 1 together with the material to the weigher 60, and the net weight of the material is obtained after removing the weight of the material table 1.

[0042] Further, in this embodiment, specifically referring to Figure 1 , near the two ends of the lead screw 3 of the material turning mechanism, there are also respectively provided two travel switches 31 in total. The two travel switches 31 are respectively electrically connected to the weigher 60, and the travel switch 31 can be actuated by the collision of the slider 4; after the travel switch 31 is collided, the weigher 60 is powered on for weighing; when the slider 4 leaves the travel switch 31, the weigher 60 is powered off to stop weighing. In the above structure, through the cooperation of the slider 4 and the travel switch 31, the weigher 60 is enabled to weigh at a preset position, and the weighing is controlled.

[0043] Further, specifically referring to Figure 1 , the oil-tea camellia seed pretreatment device of this embodiment further includes an air-source heat pump drying equipment. The air-source heat pump drying equipment includes an air-source heat pump dryer and a drying room 8. The oil-tea camellia seed pretreatment device is disposed in the drying room 8; on the ground of the drying room 8, there is provided a weigher groove 80. The weigher 60 of the material weighing mechanism is fixed in the weigher groove 80. The weighing plate 6 is flush with the ground of the drying room 8, and the material turning mechanism is fixed on the ground of the drying room 8 by the frame 20.

[0044] An oil-tea camellia seed pretreatment method using the above oil-tea camellia seed pretreatment device pre-treats the oil-tea camellia seeds by drying. On the tabletop 11 of the material table 1, there is laid the oil-tea camellia seed material to be treated. The air-source heat pump drying equipment is started to dry the oil-tea camellia seed material. The oil-tea camellia seed pretreatment device is started. The roller 5 makes the tabletop 11 of the material table 1 fluctuate to realize the turning of the oil-tea camellia seed material. The weigher 60 weighs the material table 1. After the weighing result meets the requirements, the pre-drying treatment is stopped. The air-source heat pump drying equipment is shut down, and the oil-tea camellia seed pretreatment device is shut down.

[0045] In the above method, taking the drying of camellia seeds for pressing oil as an example, the moisture content of the camellia seeds after drying is required to be 5%-8%. The water fraction value within this range is taken as the corresponding moisture content H2% when the weighing result meets the requirements. Before drying the camellia seed material, it is necessary to measure the initial weight W1 and the initial moisture content H1% of the camellia seed material. The weight W2 of the camellia seed material corresponding to the moisture content H2% after drying is calculated by W1×(1 - H1%) = W2×(1 - H2%). Then, the camellia seed material is dried and weighed according to the above method. When the net weight of the camellia seed material measured by the weighing device 60 is equal to W2, the weighing result meets the requirements and the drying is completed.

[0046] To ensure the reliability of weighing, in the camellia seed pretreatment method of this embodiment, the initial state of the camellia seed pretreatment device is set such that the slider 4 is located at one end of the lead screw 3 and collides with the travel switch 31 nearby; the forward rotation time and the reverse rotation time of the forward and reverse motor 2 are respectively set to T, and the time T is the duration for the slider 4 to move from one end of the lead screw 3 to the other end; the forward and reverse motor 2 is set to pause for a rotation time t before starting forward rotation and starting reverse rotation, and t is set to about 1 minute. When the forward and reverse motor 2 pauses for rotation, the slider 4 is located at one end of the lead screw 3 and collides with the travel switch 31 nearby, and the weighing device 60 of the camellia seed pretreatment device is powered on for weighing. The following operation steps are specifically executed:

[0047] Step 1, the air - energy heat pump drying equipment is started and operated, and the camellia seed pretreatment device is started and operated. At this time, the slider 4 is located at one end of the lead screw 3 and collides with the travel switch 31 nearby. The forward and reverse motor 2 pauses for the rotation time t, and at the same time, the weighing device 60 is powered on to weigh the material table 1.

[0048] Step 2, after the time t, the forward and reverse motor 2 starts to rotate forward or reverse. After rotating for the time T, the slider 4 moves from one end of the lead screw 3 to the other end of the lead screw 3. The forward and reverse motor 2 pauses for the rotation time t, and at the same time, the slider 4 collides with the travel switch 31 nearby, and the weighing device 60 is powered on to weigh the material table 1 again.

[0049] Step 3, repeat Step 2 until the weighing result meets the requirements, then the air - energy heat pump drying equipment stops operating, and the camellia seed pretreatment device stops operating.

[0050] In the above method, by the moving range of the slider 4 on the lead screw 3 cooperating with triggering 2 travel switches 31, during the time t when the forward and reverse motor 2 pauses for rotation, the slider 4 stops running, and the entire camellia seed pretreatment device is in a stable state. At this time, the weighing device 60 is powered on to weigh the material table 1, and the obtained weighing result is more accurate and reliable, thereby ensuring that the weighing result meets the requirements.
