Description

Technical Field

[0001] The present application relates to the technical field of rose extraction equipment, and in particular to a rose extraction equipment and an extraction method thereof for producing rose green extract juice. Background Art

[0002] Rose, as a plant that is both a medicine and food, is widely used in perfume, food, medicine and other fields. Rose essential oil, rose juice, rose dew and other basic raw materials can be extracted from fresh roses through rose extraction equipment, and rose extract can be added to fruit juice to enhance the flavor of the fruit juice. The existing rose extraction equipment includes a kettle body, the bottom of the kettle body is a steam chamber, and a heater is arranged in the steam chamber. The heater heats the water filled in the steam chamber to generate steam. The steam passes through a partition with a plurality of vents on the plate body to distill the fresh rose flowers filled in the top of the partition. The essential oil components of the rose brought out by the water vapor enter the cooling device through the connecting pipe for cooling, and finally form an oil-water mixture that flows into the oil-water separation device for oil-water separation to obtain rose extract.

[0003] However, in the process of distilling roses, the petals stacked in the kettle of traditional rose extraction equipment will gradually soften and accumulate under the action of gravity, the height of the petal layer will decrease, and the petals will stick together. The stuck petals will block the passage of water vapor through the petal layer, reducing the amount of petals in the stuck part that are exposed to water vapor and making it difficult for the essential oil components to volatilize, resulting in reduced distillation efficiency, incomplete distillation of the petals, and reduced extraction rate of the essential oil components. Secondary distillation of the flower residue is often required to fully extract the essential oil components in the rose. Moving the softened petals with a lever can easily cause the petals to break, and the volatile components other than the essential oil components in the petals will be mixed in the oil-water mixture and difficult to separate, resulting in a decrease in the quality of the essential oil. Summary of the invention

[0004] The present application proposes a rose flower extraction device and an extraction method for rose green extract juice production, which have the advantages of fully extracting the essential oil components in the rose flower with little disturbance of the petals and improving the distillation efficiency, and are used to solve the problem that the softened petals stick to each other and affect the contact efficiency and contact amount with water vapor.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a rose flower extraction device for rose green juice production, comprising a kettle body, two material carriers for carrying petals are movably arranged on the inner side of the kettle body, a plurality of vents for water vapor to pass through are opened on the top surface of the material carriers, a baffle is fixedly connected to the inner side of the kettle body near the bottom, a vent pipe is fixedly adjusted at the inner midpoint of the baffle, a solenoid valve is fixedly arranged at the bottom of the vent pipe, an adjustment mechanism is arranged on the inner side of the kettle body, and an air bag is arranged at the bottom of the kettle body; The kettle body is rotatably connected to two transmission blocks through bearings, and the adjacent sides of the two transmission blocks are fixedly connected to connecting rods, and both ends of the connecting rods are fixedly connected to arc plates, and the inner side of the arc plate is slidably sleeved with an adjustment plate for adjusting the distance between the two loading plates, and the adjustment mechanism can drive the loading plate to rotate, and the loading plate and the adjustment plate support the material in an inclined state; The regulating mechanism can open and close the electromagnetic valve and the regulating plate according to the rotation angle of the carrying plate to drive the two carrying plates to move and adjust the distance between the carrying plates. When the carrying plate is in an inclined state, the regulating mechanism switches the electric valve to be closed, and the airbag stores gas pressure. When the carrying plate is in a horizontal state, the regulating mechanism switches the electric valve to be open, and the airbag releases gas pressure. When the carrying plate is in a horizontal state, the arc plate is used to maintain contact with the wall of the kettle body.

[0006] The beneficial effects of the present invention are as follows: The present application provides a rose extraction device and an extraction method for rose green juice production. The device drives a loading plate to flip the petal layer through an adjusting mechanism transmission. The top and bottom layers of the petals are flipped when the disturbance of the petal layer is small. During the rotation, the solenoid valve is closed to store gas pressure in the airbag. After the flipping, the airbag releases the gas pressure to form a water vapor flow to flip the petals from the bottom, open the petals that are adhered to each other, and make the petals separate from the air holes to avoid the petals sticking to the outside of the air holes and blocking the air holes. The petals are inverted to achieve uniformity of the average distillation temperature of the top and bottom layers in the entire distillation process, and the loading plate is used to flip the petals to switch the effect of flipping the top and bottom layers of the petals, thereby reducing the amount of petals sticking to each other in the entire layer, so that when the disturbance is small, the petals are flipped to increase the contact amount and contact efficiency between the petals and water vapor, thereby improving the distillation efficiency and extraction rate.

DETAILED DESCRIPTION

[0009] 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.

[0010] Embodiment 1, as Figure 1 , Figure 2 , Figure 5 , Figure 6 A rose extracting device for producing rose green extract juice comprises a kettle body 1, two carrier plates 5 are movably arranged inside the kettle body 1, a plurality of vents 6 for water vapor to pass through are opened on the top surface of the carrier plate 5, the vents 6 are connected to the top and bottom surfaces of the carrier plate 5, a plurality of vents 6 are evenly arranged on the plate surface of the carrier plate 5, and the carrier plate 5 is used to carry petals, see Figure 5 The kettle body 1 is rotatably connected to two transmission blocks 23 through bearings. The two transmission blocks 23 are respectively located at the front and rear ends of the kettle body 1. The sides of the two transmission blocks 23 that are close to each other are fixedly connected to a connecting rod 14. Both ends of the connecting rod 14 are fixedly connected to an arc plate 3. The two arc plates 3 are respectively located on both sides of the two connecting rods 14.

[0011] One side of the arc-shaped plate 3 is an arc surface, which is used to fit with the inner wall of the kettle body 1 after rotating and adjusting the position, closing the gap, and preventing water vapor from passing through the gap without contacting the petals. One side of the arc-shaped plate 3 is in a U shape. An adjusting plate 4 for adjusting the distance between two loading plates 5 is slidably sleeved inside the arc-shaped plate 3. The top and bottom of one side of the adjusting plate 4 are inclined planes inclined towards the center of itself. The two sides of the loading plate 5 are inclined planes adapted to the inclined planes of the adjusting plate 4. The two sides of the loading plate 5 are respectively in contact with the two adjusting plates 4. When the two adjusting plates 4 approach each other, the inclined planes of the two adjusting plates 4 abut against the loading plate 5 therebetween, causing the two loading plates 5 to move and approach each other. That is, when the distance between the adjusting plates 4 decreases, the distance between the loading plates 5 decreases synchronously by a rated value. Refer to Figure 1 At the front and near the top of the kettle body 1, a servo motor 18 for driving the transmission block 23 to rotate is fixedly connected. The output end of the servo motor 18 is fixedly connected to the corresponding transmission block 23.

[0012] Refer to Figure 5 Refer to

[0013] The solenoid valve 11 is normally open. When the solenoid valve 11 is energized, the vent pipe 10 is closed. The servo motor 18 drives the corresponding transmission block 23 to rotate. The rotation of the transmission block 23 drives the corresponding connecting rod 14 to rotate. The connecting rod 14 drives the arc plates 3 on both sides to rotate. The connecting rod 14 is slidably connected with the adjustment plate 4. The arc plate 3 drives the corresponding adjustment plate 4 to rotate, thereby driving the two carrier plates 5 to rotate synchronously, so that the carrier plates 5 rotate and tilt. At the same time, the transmission block 23 drives the sliding contact ring 26 to rotate relative to the sliding contact block 25. When the carrier plate 5 is in a horizontal state, the sliding contact block 25 corresponds to the groove of the sliding contact ring 26, so that The solenoid valve 11 is disconnected from the circuit. When the transmission block 23 drives the carrier plate 5 to rotate and tilt, the sliding contact ring 26 rotates to contact the sliding contact block 25, and the solenoid valve 11 is started to close the ventilation pipe 10, thereby preventing the water vapor from continuously entering through the gap between the kettle body 1 and the curved plate 3 and the carrier plate 5 and contacting the petals after the rotation and tilting of the curved plate 3 and the carrier plate 5, thereby avoiding the waste of water vapor and saving energy. During the rotation process, the carrier plate 5 and the adjusting plate 4 rotate synchronously with the petals, avoiding additional disturbance damage to the petals caused by relative rotation, and ensuring the quality of essential oil extraction.

[0014] A connecting pipe 19 is fixedly connected to the top of the kettle body 1, and the connecting pipe 19 is connected to the cooling device, and the cooling device is connected to the oil-water separation device. A protrusion 8 is fixedly connected to one side of the bottom of the kettle body 1, and an air bag 9 is fixedly arranged on the inner side of the protrusion 8. A avoidance cavity is opened on the inner side of the protrusion 8, and one side of the avoidance cavity is connected to the steam cavity. The air bag 9 closes the opening of the avoidance cavity. After the vent pipe 10 is closed, water vapor continues to be generated in the steam cavity, and the air pressure increases, so that the air bag 9 expands and stores gas pressure. The loading plate 5 rotates 180° around the axis of the transmission block 23 once and then returns to the horizontal position again. The number of grooves is set to two, and the two grooves are symmetrically arranged about the axis of the sliding contact ring 26. When the loading plate 5 returns to the horizontal position, the groove corresponds to the position of the sliding contact block 25, the solenoid valve 11 is disconnected and opened, and the air bag 9 releases the stored gas pressure, so that the flow of water vapor through the ventilation groove increases, thereby impacting the petals through the water vapor and flipping the petals between the loading plates 5.

[0015] Thereby, the petals that are bonded to each other can be opened with little damage, which is convenient for the subsequent contact between water vapor and petals, increases the amount of petals that can contact water vapor, and improves the distillation efficiency and the extraction rate of essential oil extract. At the same time, the top and bottom layers of the petals between the carrier plates 5 are switched to avoid uneven water vapor temperatures at the top and bottom layers of the petals, which may lead to a decrease in the distillation efficiency of some petals. After the petal layers are switched, the air holes 6 on the carrier plates 5 that carry the petals in sequence are unblocked in coordination with the impact of water vapor to avoid the air holes 6 on the top and bottom carrier plates 5 being blocked by the bonded petals at the same time as the flipping proceeds, thereby affecting the circulation of water vapor and the contact efficiency with the petals, thereby further improving the extraction rate and efficiency of the distillation.

[0016] Embodiment 2, as Figure 1-Figure 5 On the basis of the first embodiment, an electromagnet 20 is fixedly provided on one side of the arc plate 3, and a permanent magnet 21 is fixedly provided on one side of the adjustment plate 4. The acting force between the permanent magnet 21 and the electromagnet 20 is a repulsive force, and the two adjustment plates 4 are pushed close to each other by magnetic force. The electromagnet 20 is electrically connected to the solenoid valve 11 in series. An inner rod 13 is fixedly connected to the side close to the material of one of the two loading plates 5, and an outer rod 12 is fixedly connected to the side close to the material of the other of the two loading plates 5. The number of the inner rod 13 and the outer rod 12 are both set to two and are symmetrically arranged about the center line of the corresponding loading plate 5. One side of the outer rod 12 is sleeved on the outer side of the inner rod 13, and the inner side of the outer rod 12 is movably sleeved with an adjusting spring 22, and the adjusting spring 22 is used to push the inner rod 13 to extend toward the outer side of the outer rod 12.

[0017] When the carrier plate 5 rotates and tilts, the electromagnet 20 and the electromagnetic valve 11 are synchronously connected to the circuit, and the electromagnet 20 cooperates with the permanent magnet 21 to push the two adjustment plates 4 to overcome the elastic force of the adjustment spring 22 and approach each other, so that the distance between the carrier plates 5 is reduced, and then the carrier plates 5 are rotated to tilt and respectively fit the two sides of the softened petals, and the friction force is used to prevent the petals from continuing to accumulate and adhere under gravity and to prevent the petal layer from collapsing, until the carrier plate 5 rotates to the horizontal again, the electromagnet 20 is disconnected, and the adjustment spring 22 pushes the two carrier plates 5 to reset, and the adjustment plate 4 is reset, leaving space for the subsequent water vapor airflow to flip the petals, refer to Figure 2 A discharge port 17 is provided at the bottom of the kettle body 1, and a feed port 16 is provided at the top of the kettle body 1. The discharge port 17 and the feed port 16 are both detachably closed by a closing cover during distillation. The positions of the discharge port 17 and the feed port 16 are respectively adapted to the material layer when the loading plate 5 is rotated to an inclined state. The positions of the discharge port 17 and the feed port 16 can also be set to be adapted to the material layer when the loading plate 5 is rotated to a vertical state. The circuit connected to the electromagnet 20 is provided with a circuit switch. When feeding and discharging, the servo motor 18 drives the loading plate 5 to rotate to an inclined state, and the corresponding circuit switch of the electromagnet 20 is switched to off, the electromagnet 20 is not started, and the two loading plates 5 are opened for easy feeding. When discharging, the inclined or vertical softened petal layers are piled together under the action of gravity for easy discharging.

[0018] Embodiment three, as Figure 1 , Figure 2 and Figure 5On the basis of the second embodiment, a partition plate 7 is fixedly connected to one side where the two transmission blocks 23 are close to each other. A plurality of through holes are provided on the top surface of the partition plate 7. The partition plate 7 rotates synchronously with the carrier plate 5. When rotating to an inclined state, the partition plate 7 increases the contact area with the petal layer, further ensuring that the petal layer is flipped when the disturbance of the petal layer is small. At the same time, after flipping, the partition plate 7 separates the petal layer into two layers, and the water vapor airflow drives the single layer to flip more easily, further ensuring the reliability of flipping the petal layer. A thermistor 15 is fixedly arranged on one side of the bottom of the baffle 2. The thermistor 15 and the electromagnet 20 is connected to the circuit in series, and the circuit current does not affect the opening and closing of the solenoid valve 11. The solenoid valve 11 only has fully open and fully closed states. After filling the material, the resistance value of the thermistor 15 decreases with the increase of temperature. In the process of the petals changing from an incompletely softened state to a completely softened state, the servo motor 18 is started at a rated time interval, and the magnetic force of the electromagnet 20 gradually increases each time, so that the distance between the two loading plates 5 each time is gradually reduced, which is adapted to the thickness of the gradually softened petals, further reducing the disturbance to the petal layers, and improving the reliability of the extraction equipment.
