Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rose screening devices, specifically a rose screening device for extracting rose essential oil. Background Technology
[0002] Rose essential oil is a highly concentrated, highly volatile aromatic substance extracted from rose petals using a specific method. It is one of the most precious and popular essential oils in aromatherapy and high-end skincare products. The extraction process for rose essential oil is as follows: First, rose petals are placed in an extraction tank, and a volatile organic solvent is added. The solvent is then evaporated and recovered, leaving a dark, semi-solid, waxy substance. Next, the resin is mixed with alcohol and stirred, and the insoluble matter is separated by freeze filtration. The alcohol is then evaporated under low-temperature vacuum, ultimately yielding highly concentrated rose absolute rich in its full aroma. The main raw material for rose essential oil extraction is rose petals. After harvesting, the rose petals need to be screened to remove withered leaves and rotten or unsuitable petals.
[0003] To prevent damage to delicate rose petals during the selection process, which could break the cell walls and affect the oil yield, a combination of mechanical and manual screening is currently used. However, high-precision machinery cannot yet be used to select moldy or substandard petals, so this step must be done manually. During screening, workers need to turn over piled petals. On the one hand, repeatedly turning the petals can easily cause damage; on the other hand, manual turning is inefficient, reducing the efficiency of rose essential oil extraction.
[0004] To address these issues, this invention provides a rose screening device for extracting rose essential oil. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a rose screening device for rose essential oil extraction, which solves the aforementioned problems.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rose screening device for extracting rose essential oil, comprising a mounting frame consisting of a mounting plate and a support rod, a material discharge plate fixedly connected to the top of the support rod, a mounting shell mounted on the top of the material discharge plate, a conveyor belt mounted inside the mounting shell, a discharge box mounted on one side of the mounting shell, a baffle plate mounted on the top of the mounting shell, an airflow screening component mounted on the top of the baffle plate, and a manual screening component mounted on the top of the mounting plate;
[0007] The manual screening assembly includes a connecting plate and a connecting frame fixedly connected to the top of the mounting plate. Side rods are symmetrically fixedly connected to the inner side of the connecting plate, and limiting grooves are provided on the outer side of the side rods. A sieve plate is installed between the connecting plate and the connecting frame.
[0008] Preferably, the mounting shell is bent, and the shapes of the material drop plate and the shield plate match the shape of the mounting shell.
[0009] Preferably, a material discharge hole is provided on one side of the material discharge plate.
[0010] Preferably, a guide plate is installed on the outer side of the conveyor belt, and screen holes are opened on the outer side of both the conveyor belt and the screen plate.
[0011] Preferably, the airflow screening assembly includes a feed box fixedly connected to the top of the inclined section of the mounting shell, an air jet is installed inside the feed box, a filter box is installed on the top of the feed box, a dust collector bag is installed on the outside of the filter box, and a sealing cover is hinged to the outside of the filter box.
[0012] Beneficial effects
[0013] This invention provides a rose screening device for extracting rose essential oil. Compared with the prior art, it has the following advantages:
[0014] The rose sieving device for rose essential oil extraction uses an airflow sieving component to initially sift dust and broken leaves from the petals. The petals then fall onto the upper surface of a sieve plate. Workers manually sift through the inner impurities and unsuitable petals of the upper layer. After sieving, the sieve plate between the connecting plates is rotated repeatedly. Due to the tilt of the sieve plate, the positions of the upper and lower petals on the sieve plate surface are exchanged, facilitating further sieving by the workers. During the sieving process, workers do not need to repeatedly turn the petals by hand, reducing their workload and preventing damage to the leaves caused by repeated turning, which would affect the extraction efficiency and quality of the rose essential oil.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please see Figure 1-3 A rose screening device for extracting rose essential oil includes a mounting frame consisting of a mounting plate 1 and a support rod 2. A material drop plate 3 is fixedly connected to the top of the support rod 2. A mounting shell 4 is installed on the top of the material drop plate 3. A conveyor belt 5 is installed inside the mounting shell 4. A discharge box 6 is installed on one side of the mounting shell 4. A baffle plate 7 is installed on the top of the mounting shell 4. An airflow screening component 8 is installed on the top of the baffle plate 7. A manual screening component 9 is installed on the top of the mounting plate 1.
[0023] The manual screening component 9 includes a connecting plate 901 and a connecting frame 902 fixedly connected to the top of the mounting plate 1. Side rods 903 are symmetrically fixedly connected to the inner side of the connecting plate 901. A limiting groove 904 is provided on the outer side of the side rods 903. The included angle of the limiting groove 904 is 60°. A sieve plate 905 is installed between the connecting plate 901 and the connecting frame 902. The connecting frame 902 has a triangular cross-section. The connecting frame 902 and the sieve plate 905 are rotatably connected. One end of the sieve plate 905 is connected to the two side rods 903 through a locking post.
[0024] The bottom of the unloading box 6 is truncated pyramidal, and the unloading port of the unloading box 6 corresponds to the position of the screen plate 905.
[0025] In this embodiment, during the initial screening of rose petals, the collected rose petals are poured onto the conveyor belt 5 inside the mounting housing 4 by mechanical or manual pouring. At this time, the airflow screening component 8 first performs preliminary treatment on the dust and broken leaves in the petals. The conveyor belt 5 transports the petals to the unloading box 6, and the petals fall from the unloading box 6 onto the upper surface of the screen plate 905. In addition, withered leaves, leaf stalks, rotten petals, and non-compliant petals need to be manually screened. The processing personnel rotate the screen plate 905 between the connecting plate 901 and the connecting frame 902 by a small amplitude, so that the petals on the upper surface of the screen plate 905 are spread out. The staff manually removes the impurities and non-compliant petals inside the upper petals. After screening the upper petals, the screen plate 905 is rotated by a large amplitude. By repeatedly tilting the screen plate 905, the positions of the upper and lower petals on the upper surface of the screen plate 905 are exchanged. The staff screens the petals again. Through repeated screening operations, the efficiency of removing impurities and non-compliant petals is improved.
[0026] Example 2:
[0027] Please see Figure 1-2 This embodiment provides a rose screening device for rose essential oil extraction based on embodiment one: the mounting shell 4 is a bent shape composed of inclined section and parallel section, the shape of the material drop plate 3 and the baffle plate 7 matches the shape of the mounting shell 4, and the airflow screening component 8 is installed at the inclined section position of the baffle plate 7.
[0028] A material discharge hole is provided on one side of the material discharge plate 3, and the material discharge hole is located at the inclined section of the material discharge plate 3.
[0029] A guide plate is installed on the outer side of the conveyor belt 5. Screen holes are opened on the outer side of both the conveyor belt 5 and the screen plate 905. The two sets of screen holes have the same diameter.
[0030] In this embodiment, the bent mounting shell 4 causes part of the conveyor belt 5 to be inclined. During the transportation of petals, some gravel falls from the sieve holes on the surface of the conveyor belt 5. During the manual screening of petals, the repeatedly tilted sieve plate 905 causes gravel and some broken leaves to fall from the sieve holes on its outer surface.
[0031] Example 3:
[0032] Please see Figure 2 and Figure 4This embodiment provides a rose screening device for rose essential oil extraction based on embodiment one: the airflow screening component 8 includes a feed box 801 fixedly connected to the top of the inclined section of the mounting shell 4. An air jet head 802 is installed inside the feed box 801. A filter box 803 is installed on the top of the feed box 801. The inner wall of the filter box 803 is arc-shaped and has filter holes on the outside. A filter screen is installed inside the filter holes. A dust collector bag 804 is installed on the outside of the filter box 803. The dust collector bag 804 is connected to the filter box 803. A sealing cover 805 is hinged to the outside of the filter box 803. The output port diameter of the feed box 801 is much smaller than the transverse receiving area of the conveyor belt 5.
[0033] In this embodiment, during the initial screening of petals, airflow is ejected from the jet nozzle 802 inside the feed box 801. The ejected airflow causes the petals inside the feed box 801 to float, thereby removing dust adhering to the surface of the petals. At the same time, the dust enters the dust collector bag 804 through the filter holes of the filter box 803 for collection. Cleaning the dust can prevent the dust adhering to the petals from affecting the quality of rose essential oil extraction. The filter box 803, with its arc-shaped inner wall, guides the airflow. Since the output port diameter of the feed box 801 is much smaller than the lateral receiving area of the conveyor belt 5, it can prevent a large number of petals from getting stuck in the gap between the drop plate 3 and the conveyor belt 5, thus avoiding jamming of the conveyor belt 5.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] Working principle:
[0036] The collected petals are poured into the feed box 801 by manual or mechanical unloading. At this time, the conveyor belt 5 is in standby mode. Airflow is introduced into the jet nozzle 802 inside the feed box 801 through an external airflow pipe. The airflow from the jet nozzle 802 blows the petals, causing some of the dust and grit attached to the petals to fall off. Some of the dust and grit fall into the inside of the discharge plate 3 through the screen holes on the outside of the conveyor belt 5 and is blocked by the baffle plate 7. At the same time, because the inner wall of the filter box 803 is curved, some of the airflow carrying dust down the inner wall... The arc-shaped filter box 803 enters the dust collector bag 804 through its outer filter holes. The filter screen inside the filter holes blocks the petals. Simultaneously, the amount of petals added to the feed box 801 is adjusted, and the airflow from the jet nozzle 802 is controlled to prevent the petals from contacting the top of the inner wall of the filter box 803, thus avoiding clogging the filter holes and preventing petals from entering the dust collector bag 804. After the initial screening of the petals, the conveyor belt 5 is started, moving the petals towards the unloading box 6. The outer side of the conveyor belt 5 is equipped with screen holes, allowing some broken leaves and gravel to fall into the discharge plate 3 and be discharged from the discharge holes on the outer side of the discharge plate 3. After the initial screening, the petals fall onto the upper surface of the screen plate 905. At this time, the drive power of the conveyor belt 5 is turned off to prevent petals from falling onto the mounting plate 1 through the gap between the connecting plate 901 and the screen plate 905 when the screen plate 905 is tilted during the manual screening process, which would cause contamination or waste of the rose raw materials. The processing personnel can prevent this by slightly rotating the screen plate 905 between the connecting plate 901 and the connecting frame 902. 05, so that the petals piled on the surface of the sieve plate 905 are flattened. At this time, withered leaves, branches and unsuitable petals in the upper layer of petals are removed by manual screening. After screening the impurities in the upper layer of petals, the sieve plate 905 is rotated significantly. By repeatedly rotating the sieve plate 905, the upper and lower layers of petals are swapped due to the tilt of the sieve plate 905. At this time, the processing personnel screen the petals again. Through repeated screening operations, the quality of the collected petals is improved, thereby improving the quality of essential oil extraction.
