Description

A citrus oil grinding device with high essential oil extraction rate Technical Field

[0001] This utility model relates to the field of oil grinding equipment technology, specifically to a citrus oil grinding device with a high essential oil extraction rate. Background Technology

[0002] Citrus peel essential oil is a byproduct of deep processing, with wide market applications and extremely high added value. Citrus oil extraction equipment is mainly used for extracting essential oils from the peels of citrus fruits (oranges, lemons, grapefruits, pomelos, etc.). This equipment typically uses six needle rollers, with two rollers rotating in opposite directions in pairs. Its working principle involves applying mechanical friction to the citrus peel through the high-speed rotating needle rollers, precisely piercing the oil cells to release the essential oil.

[0003] The high-pressure spray system is the core unit for achieving efficient extraction of essential oils. It uses high-pressure water jets to flush the oil cells on the surface of citrus fruits, causing the released essential oils to detach from the skin and form an oil-water mixture. The high-purity essential oils are then separated by a centrifuge.

[0004] Existing citrus oil refining equipment typically arranges multiple spray pipes above the needle rollers, with nozzles on the pipes spraying high-pressure mist downwards. Because the equipment also incorporates a rotating pushing mechanism to move the citrus fruits on the needle rollers, the spray pipes must be installed at a certain distance from the rollers, which affects the rinsing coverage area. Furthermore, during production, the citrus fruits mainly accumulate between the two opposing rotating needle rollers, and the spray pipes cannot completely cover this portion of the tumbling path, thus affecting rinsing efficiency and consequently impacting the collection and extraction efficiency of the essential oil. Summary of the Invention

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a citrus oil grinding device with a high essential oil extraction rate, so as to increase the rinsing coverage area and improve the rinsing effect on essential oils that have been separated from the oil cells.

[0006] To achieve the above objectives, this utility model provides a citrus oil grinding device with a high essential oil extraction rate, comprising a frame with a collection trough; multiple piercing components disposed within the frame, each piercing component including two needle rollers arranged side-by-side above the collection trough, the two needle rollers rotating towards each other, the needle rollers being used to pierce the oil cells of the citrus peel; a pushing component for pushing the citrus fruit tumbling on the needle rollers; a driving component for driving each piercing component and the pushing component to work; and multiple baffle blocks, each baffle block corresponding to one piercing component, the baffle blocks being disposed between two needle rollers;

[0007] Multiple lifting spray assemblies, each corresponding to one of the material stop blocks, each lifting spray assembly includes multiple first spray pipes and a lifting drive component. The first spray pipes are vertically movably inserted through the material stop blocks, and the multiple first spray pipes are spaced apart along the length of the material stop blocks. The top end of each first spray pipe is closed, and the circumferential sidewall of each first spray pipe has multiple water outlet holes near the top end of the first spray pipe. The lifting drive component is used to drive the first spray pipes to perform lifting and lowering actions. Multiple second spray pipes are spaced apart above the needle-punching roller. A water supply assembly is also included to supply water to the first and second spray pipes respectively.

[0008] Preferably, the first spray pipe is provided with a first nozzle, and the nozzle orifice is arranged facing upward; a diverter is provided on the cavity wall near the top of the first spray pipe, and the diverter is used to divert the water sprayed from the first nozzle to each of the water outlets.

[0009] Preferably, the diverter has an inverted conical structure, and the cavity wall of the first spray pipe near its top is provided with an annular guide groove. The annular guide groove surrounds the diverter and has an upwardly concave guide surface. The guide surface is connected to the conical surface of the diverter and the hole wall of the water outlet, respectively.

[0010] Preferably, the first spray pipe includes a pipe body and a pipe cap, the pipe body is connected to the lifting drive component, and the first nozzle is inserted into the pipe body; the pipe cap is detachably connected to the pipe body, the water outlet is provided on the circumferential side wall of the pipe cap, and the diverter is provided on the inner end cap of the pipe cap.

[0011] Preferably, the pipe body is provided with a leak-proof plug inside the pipe opening, and the first nozzle is inserted into the leak-proof plug.

[0012] Preferably, the inner wall of the cap is provided with a limiting flange, the limiting flange extends circumferentially along the cap, and the limiting flange can abut against the end face of the first nozzle.

[0013] Preferably, the lifting spray assembly further includes a first support frame, each of the first spray pipes is disposed on the first support frame, and the lifting drive component is connected to the first support frame.

[0014] Preferably, the lifting spray assembly further includes a housing, which is disposed below the needle roller, the first spray pipe is movably inserted through the housing, and the first support frame and the lifting drive are both disposed inside the housing; a second support frame is provided in the collection trough, and the lifting drive and the housing are both disposed on the second support frame.

[0015] The beneficial effects of this utility model are:

[0016] This utility model discloses a citrus oil grinding device with a high essential oil extraction rate. By designing a lifting spray assembly, high-pressure water can be sprayed from multiple water outlets of the first spray pipe. When the lifting drive drives all the first spray pipes to rise and fall, the first spray pipes can rinse the citrus in the piercing station. With the cooperation of the second spray pipe, the rinsing coverage of the piercing station is increased, the rinsing dead corners are reduced, and the rinsing effect of essential oil detached from the oil cells is improved, so that more essential oil can flow into the collection tank, thereby improving the collection and extraction efficiency of essential oil.

[0017] Since the citrus fruits mainly accumulate between the two needle rollers (the two needle rollers of the piercing component), by adjusting the first spray pipe to be raised and lowered to fit the baffle block, the water outlet of the first spray pipe is brought closer to the tumbling citrus fruits, further enhancing the rinsing effect on the essential oils and promoting even tumbling of the citrus fruits, effectively reducing fruit adhesion and dead zones for oiling. Furthermore, the cylindrical shape of the first spray pipe prevents the citrus fruits from interfering with its descent, and the first spray pipe also prevents the citrus fruits from being pressed against the baffle block, thus avoiding damage to the citrus fruits.

[0037] As shown in Figures 1-10, in one embodiment of this utility model, a citrus oil grinding device with high essential oil extraction rate is provided, including a frame 10, three piercing components 20, a pushing component 30, a drive component, three baffle blocks 40, three lifting spray components 50, multiple second spray pipes 60, and a water supply component. The frame 10 has a collection trough 11 and three piercing stations, with each piercing component 20 installed in its corresponding station. Each piercing component 20 includes two needle rollers 21 arranged side-by-side above the collection trough 11, rotating in opposite directions. The outer surface of each needle roller 21 is uniformly covered with needle-like spikes, used to pierce the oil cells in the citrus peel. A partition 12 is installed between adjacent piercing stations. The pushing component 30 is used to push the citrus fruit tumbling on the needle rollers 21, and includes multiple push plates 31 and a sprocket and chain assembly. A drive assembly (not shown in the attached diagram) drives each needle-punching roller 21 to rotate and the pusher plate 31 to rotate, thereby pushing the oranges tumbling on the needle-punching rollers 21 to the discharge port of the frame 10. Each stop block 40 corresponds to one puncturing assembly 20. The stop block 40 is located between two needle-punching rollers 21 and is used to prevent oranges from being pressed into the gap between the two opposing rotating needle-punching rollers 21.

[0038] Each lifting spray assembly 50 corresponds to a stop block 40. The lifting spray assembly 50 includes multiple first spray pipes 51 and a lifting drive component 52. The stop block 40 has multiple through holes through which the first spray pipes 51 can pass. The cylindrical first spray pipes 51 are vertically movably inserted through the through holes. The multiple first spray pipes 51 are arranged at intervals along the length of the stop block 40. The top of the first spray pipe 51 is closed. The circumferential sidewall of the first spray pipe 51 has multiple water outlet holes 511, which are close to the top of the first spray pipe 51. The lifting drive component 52 is used to drive the first spray pipes 51 to perform lifting and lowering actions. Of course, referring to Figure 9, the push plate 31 also has an appropriate notch for the first spray pipes 51 to pass through. In this way, whether the first spray pipes 51 are raised or not, it will not affect or interfere with the normal movement of the push plate 31.

[0039] Multiple second spray pipes 60 are arranged at intervals above the needle roller 21. The second water supply assembly (not shown in the figure) is used to provide high-pressure water to the first spray pipe 51 and the second spray pipe 60 respectively, so that the first spray pipe 51 and the second spray pipe 60 spray high-pressure water.

[0040] This embodiment discloses a citrus oil grinding device with a high essential oil extraction rate. It is designed with a lifting spray assembly 50, in which high-pressure water can be sprayed from multiple water outlets 511 of the first spray pipe 51. When the lifting drive 52 drives all the first spray pipes 51 to rise and fall, the first spray pipes 51 can rinse the citrus in the piercing station. With the cooperation of the second spray pipe 60, the rinsing coverage of the piercing station is increased, the rinsing dead corners are reduced, and the rinsing effect of essential oil detached from the oil cells is improved, so that more essential oil can flow into the collection tank 11, thereby improving the collection and extraction efficiency of essential oil.

[0041] Since the citrus fruits mainly accumulate between the two needle rollers 21 (the two needle rollers 21 of the puncture assembly 20), by raising and lowering the first spray pipe 51 to cooperate with the baffle block 40, the water outlet of the first spray pipe 51 is brought closer to the tumbling citrus fruits, further improving the rinsing effect on the essential oil and promoting the uniform tumbling of the citrus fruits, effectively reducing fruit adhesion and dead corners for oiling. Furthermore, during the descent of the cylindrical first spray pipe 51, the citrus fruits will not interfere with its descent, and the first spray pipe 51 will not press the citrus fruits onto the baffle block 40, thus avoiding damage to the citrus fruits.

[0042] In one embodiment, a first nozzle 53 is provided inside the first spray pipe 51, with the nozzle orifice facing upwards. A diverter 512 is provided on the cavity wall near the top of the first spray pipe 51 to divert the water sprayed from the first nozzle 53 to each water outlet 511. A plurality of second nozzles are arranged at intervals on the second spray pipe 60, with the nozzle orifice facing downwards.

[0043] Specifically, the diverter 512 has an inverted conical structure, and the spray holes of the first spray pipe 51, the diverter 512, and the first nozzle 53 are arranged coaxially. The cavity wall of the first spray pipe 51 near its top end is provided with an annular guide groove 513, which surrounds the diverter 512. The annular guide groove 513 is provided with an upwardly recessed guide surface 514, which is connected to the conical surface of the diverter 512 and the wall of the outlet hole 511, respectively.

[0044] By arranging multiple water outlets 511 on the circumferential sidewall of the first spray pipe 51, the high-pressure spray from the first nozzle 53 will be sprayed out from the circumference of the vertically arranged first spray pipe 51, thereby expanding the rinsing coverage of the first spray pipe 51.

[0045] Due to the design of the outlet hole 511, if the high-pressure spray from the first nozzle 53 directly hits the cavity wall near the top of the first spray pipe 51, it may affect the service life of the first spray pipe 51 and cannot guarantee the uniformity of water output from the outlet hole 511. Therefore, by designing a diverter 512 with an inverted cone structure, the high-pressure spray from the first nozzle 53 is diverted by the cone surface of the diverter 512 and then passes through the guide surface 514, so that the high-pressure spray can be sprayed out from each outlet hole 511 as evenly as possible. This not only reduces the impact force of the high-pressure spray on the cavity wall near the top of the first spray pipe 51, but also improves the uniformity of water output from the first spray pipe 51.

[0046] In addition, the guide surface 514 will guide the high-pressure spray as far downward as possible out of the water outlet 511. Therefore, during the process of the lifting drive 52 driving the first spray pipe 51 to rise, the rinsing coverage of the first spray pipe 51 is wider, and the first spray pipe 51 can rinse the two needle rollers 21 and the partitions 12 on both sides, so that more essential oil can flow into the collection tank 11, thereby improving the collection and extraction efficiency of essential oil.

[0047] In one embodiment, the first spray pipe 51 includes a pipe body 515 and a pipe cap 516. The pipe body 515 is connected to a lifting drive component 52. A leak-proof plug 54 is provided inside the pipe opening of the pipe body 515, and the first nozzle 53 is inserted into the leak-proof plug 54. The pipe cap 516 is detachably connected to the pipe body 515 by threads. A water outlet 511 is provided on the circumferential sidewall of the pipe cap 516, and a flow divider 512 is provided on the inner end cap of the pipe cap 516. By designing the first spray pipe 51 as a split structure, it is not only easier to process the first spray pipe 51, but also easier to install the first nozzle 53 inside the pipe body 515, which is beneficial for later maintenance.

[0048] In one embodiment, in order to further enhance the fastening effect on the first nozzle 53, the inner sidewall of the cap 516 is integrally formed with a limiting flange 517, which extends circumferentially along the cap 516 and can abut against the end face of the first nozzle 53.

[0049] In one embodiment, the lifting spray assembly 50 further includes a first support frame 55, with each first spray pipe 51 mounted on the first support frame 55, and a lifting drive component 52 connected to the first support frame 55. In this embodiment, each lifting spray assembly 50 has two lifting drive components 52, which are waterproof cylinders (stainless steel cylinders). As the two lifting drive components 52 lift the first support frame 55, each first spray pipe 51 gradually extends upward. If the two lifting drive components 52 intermittently and rapidly push the first support frame 55 up and down, the first spray pipes 51 can also push up some of the piled-up citrus fruits, thereby preventing the citrus fruits from piling up.

[0050] In one embodiment, the lifting spray assembly 50 further includes a housing 56, which is located below the needle roller 21. The first spray pipe 51 is movably inserted through the housing 56, and the first support frame 55 and the lifting drive component 52 are both located inside the housing 56. A second support frame 13 is provided inside the collection tank 11, and the lifting drive component 52 and the housing 56 are both located on the second support frame 13. The oil-water mixture can flow into the collection tank 11 along the outer wall of the housing 56. The housing 56, while protecting the lifting drive component 52 and the first support frame 55, can also guide the oil-water mixture.

[0051] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
