[0002] Torreya grandis is a variety of the excellent mutation of the Torreya grandis of the Taxaceae family that has been cultivated through artificial selection and grafting. It is a special economic tree species that combines edible, medicinal, timber, oil and greening uses. It is a unique economic tree species in my country and has always been highly favored and recognized.

[0003] In recent years, the research on Torreya grandis aril has received great attention. Studies have shown that Torreya grandis aril contains a variety of aromatic terpenoid components such as alcohols, aldehydes, ketones, alkenes, and flavonoid components, and has antibacterial, antioxidant, and insect repellent effects. However, Torreya grandis aril is currently a large amount of waste in the Torreya grandis processing process, which not only wastes resources but also causes environmental pollution.

[0004] However, although essential oil can be extracted from Torreya grandis arils, the following problems often exist in actual application: (1) For scattered or low-yield Torreya grandis arils production areas, if investment is made to establish an aril processing plant, large-scale instruments and equipment and chemical reagents are required, which requires a large amount of investment and is obviously not in line with the actual situation in the planting area; (2) Torreya grandis arils are extremely easy to rot and deteriorate, making it difficult to transport them to the processing plant over long distances. Refrigeration or drying will also increase costs, and the effect of extracting essential oils is not as good as that of fresh Torreya grandis arils; (3) Existing extraction and separation technologies are difficult, and the waste generated by the extraction is difficult to handle.

DETAILED DESCRIPTION

[0019] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Several embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] First embodiment See also Figure 1-Figure 5 The first embodiment of the present invention provides a separation and extraction system for Torreya grandis aril essential oil, the system comprising: a pressing mechanism 10, a distillation mechanism 20, a condensation mechanism 30 and an oil-water separation mechanism 40, the above mechanisms are connected in sequence to achieve the separation and extraction of Torreya grandis aril essential oil.

[0023] In the present embodiment, the pressing mechanism 10 includes a mesh bag 11 for containing Torreya grandis aril and a squeezing plate 12, wherein the mesh bag 11 is a multi-channel mesh bag, which is used to contain Torreya grandis aril to be squeezed, and the mesh bag 11 containing Torreya grandis aril is used to be placed in a cylinder 14 of the pressing mechanism 10, and the squeezing plate 12 can also be inserted into the cylinder 14 to squeeze the mesh bag 11 containing Torreya grandis aril, wherein the squeezing plate 12 is driven by a hydraulic drive structure 15 to allow the squeezing plate 12 to retract in the cylinder 14, thereby enabling the squeezing plate 12 to squeeze the mesh bag 11 containing Torreya grandis aril in the cylinder 14, and the Torreya grandis aril in the mesh bag 11 can overflow the squeezing liquid under the squeezing action, thereby achieving the squeezing of the Torreya grandis aril.

[0024] In this embodiment, in order to improve the squeezing efficiency and squeezing effect of the Torreya grandis aril, a plurality of protrusions are provided on the surface of the squeezing disk 12 facing the mesh bag 11. The plurality of protrusions can be arranged in a grid shape, for example, to form a convex rib structure similar to a chessboard, so that the pressure can be evenly transmitted when squeezing the Torreya grandis aril in the mesh bag 11. The mesh bag 11 is provided with cross flocking inside. When the Torreya grandis aril is placed inside the mesh bag 11, the Torreya grandis aril can form several layers inside the mesh bag 11, providing a liquid passage for the overflow of the squeezed liquid, reducing the stress consumption caused by squeezing inside the Torreya grandis aril, and the squeezed liquid after squeezing will reach the outside of the mesh bag 11 along the liquid passage between the cross flocking to further converge. The cylinder 14 is provided with an inner cylinder and an outer cylinder. The inner cylinder is provided with a plurality of sieve holes for discharging the squeezed liquid gathered outside the mesh bag 11, and the outer cylinder is the outermost layer of the cylinder 14 for providing structural stability and preliminarily collecting the squeezed liquid.

[0025] Among them, the outer cylinder of the cylinder 14 is connected to a liquid outlet channel 13, which is made of, for example, bent metal material and connected to the bottom of the outer cylinder in the cylinder 14. The squeezed liquid produced by the squeezing will flow into the liquid outlet channel 13 along the drainage hole opened at the bottom of the outer cylinder, thereby realizing the squeezing and preliminary collection of the Torreya grandis aril.

[0026] Of course, in the process of squeezing the Torreya grandis aril in the mesh bag 11, an intermittent squeezing method can be used for squeezing. For example, after a preset squeezing time, the mesh bag 11 is turned over to turn over the Torreya grandis aril in the mesh bag 11, which can improve the yield of the squeezed liquid.

[0027] After the Torreya grandis aril is squeezed to obtain a squeezed liquid, in order to extract the essential oil contained in the squeezed liquid, the present embodiment first needs to distill the squeezed liquid, and specifically uses the distillation mechanism 20 shown in the present embodiment to perform the distillation process.

[0028] The distillation mechanism 20 shown in this embodiment includes a distillation tank 21, which is usually a metal tank body and is required to withstand high temperature and high pressure. A feed pipe 23 is connected between the distillation tank 21 of the distillation mechanism 20 and the liquid outlet channel 13 of the pressing mechanism 10. The feed pipe 23 and the liquid outlet channel 13 can be arranged in an inclined manner so that the squeezed liquid can naturally flow into the distillation tank 21 under the action of gravity. Of course, a related liquid pump can also be used to drive the squeezed liquid to flow quickly. When the squeezed liquid enters the distillation tank 21, the squeezed liquid will gradually gather at the bottom of the distillation tank 21, and then the squeezed liquid in the distillation tank 21 will be distilled by introducing steam.

[0029] The distillation tank 21 is provided with a steam delivery pipe 24, which can, for example, be directly introduced into the distillation tank 21 to distill the squeezed liquid, thereby causing the squeezed liquid to volatilize essential oil.

[0030] In this embodiment, the distillation mechanism 20 further includes a steam guide assembly 22 disposed in the distillation tank 21, which is used to guide the steam entering the distillation tank 21, thereby improving the distillation efficiency.

[0031] The steam guide assembly 22 includes a steam guide plate 221 and a steam nozzle 222 disposed on the steam guide plate 221. The steam guide plate 221 is connected to a steam delivery pipe 24 on the distillation tank 21 for introducing steam, and the steam guide plate 221 is also connected to the steam nozzle 222. The steam nozzle 222 is actually connected to the steam delivery pipe 24. When steam is delivered to the distillation tank 21 through the steam delivery pipe 24, the steam can be ejected from a plurality of steam nozzles 222 through the steam guide plate 221, so that the steam acts on the squeezed liquid in multiple directions. The steam guide assembly 22 shown in this embodiment can improve the distillation efficiency by guiding the steam.

[0032] Specifically, the steam guide plate 221 is arranged at the bottom of the distillation tank 21, and the steam nozzle 222 arranged on the steam guide plate 221 is arranged on the lower surface of the steam guide plate 221, that is, the steam nozzle 222 is facing the bottom of the distillation tank 21. This is because when the pressed liquid output by the pressing mechanism 10 flows into the distillation tank 21 through the liquid outlet channel 13 and the liquid outlet pipe, the pressed liquid will gather at the bottom of the distillation tank 21. Then, by making the steam nozzle 222 spray steam toward the bottom of the distillation tank 21, the distillation efficiency can be improved.

[0033] In addition, the steam guide plate 221 is not a planar structure but an arc-shaped structure. The several steam nozzles 222 installed on the lower surface of the steam guide plate 221 can naturally face multiple directions, which is conducive to the dispersion of steam in the distillation tank 21. Correspondingly, the bottom of the distillation tank 21 is also an arc-shaped structure. When the steam contacts the bottom of the distillation tank 21, the steam can further diffuse, so that the steam can quickly spread to various areas in the distillation tank 21, so as to achieve the effect of rapid temperature and pressure increase, thereby improving the distillation efficiency.

[0034] It should be noted here that by adopting the steam diversion method to quickly establish a high-temperature and high-pressure environment in the distillation tank 21, the squeezed liquid collected in the distillation tank 21 in advance can be quickly distilled, and the essential oil components contained in the squeezed liquid will be quickly distilled out. The essential oil distilled from the squeezed liquid will follow the steam to be discharged into the condensation mechanism 30 for condensation treatment.

[0035] In the present embodiment, the condensing mechanism 30 includes a condenser, and the condenser is connected to the distillation tank 21 via a condensing duct 33. It should be noted that the condensing duct 33 here does not have a condensing function, but is named as an input pipe of the condensing mechanism 30 for the convenience of description.

[0036] During the process of distilling the squeezed liquid by the distillation mechanism 20, the essential oil from the squeezed liquid is continuously distilled and output. The essential oil is a gaseous volatile substance and can be collected at the top of the distillation tank 21. Then, it is discharged along with the steam that needs to be discharged from the distillation tank 21. It is introduced into the condenser through the condensation duct 33 for cooling treatment. In this way, the gaseous essential oil and steam can be condensed to generate a liquid oil-water mixture.

[0037] It should be noted here that in the process of continuously introducing steam into the distillation tank 21, the temperature and pressure in the distillation tank 21 will rise rapidly. In order to keep the pressure in the distillation tank 21 within the safety threshold, part of the steam in the distillation tank 21 also needs to be continuously discharged. The essential oil volatiles suspended at the top of the distillation tank 21 can be discharged along with the steam to be condensed at the same time.

[0038] Specifically, in this embodiment, the condenser in the condensation mechanism 30 includes a primary condenser 31 and a deep condenser 32. The input end of the primary condenser 31 is connected to the distillation tank 21 through the above-mentioned condensation duct 33, and the output end of the primary condenser 31 is connected to the input end of the deep condenser 32, and the output end of the deep condenser 32 is used to connect to the oil-water separation mechanism 40.

[0039] Among them, the working principles of the primary condenser 31 and the deep condenser 32 are not explained in detail here, and they can be set up with reference to the existing condensers. The characteristic point is that the condensing mechanism 30 shown in this embodiment includes two condensers, namely the primary condenser 31 and the deep condenser 32, which are connected in series between the distillation mechanism 20 and the oil-water separation mechanism 40, so as to perform double condensation treatment on the gaseous essential oil volatiles and steam, thereby improving the depth and breadth of the condensation treatment and avoiding the waste of the gaseous essential oil volatiles originating from the Torreya grandis aril.

[0040] After the gaseous essential oil volatiles and steam are condensed by the condensation mechanism 30 to generate an oil-water mixture, in order to facilitate the collection of Torreya aril essential oil, the oil-water mixture is also separated by an oil-water separation mechanism 40 in this embodiment, specifically, Torreya aril essential oil and condensed water are separated, and finally the Torreya aril essential oil can be collected.

[0041] In this embodiment, the oil-water separation mechanism 40 includes a light oil separator 41, which includes a separator housing 411. A vortex cooler 413 is provided in the separator housing 411. The vortex cooler 413 includes a spiral vortex pipe 414 and a cooling water inlet pipe 415 connected to the upper end of the vortex pipe 414. The cooling water inlet pipe 415 passes through the separator housing 411 to introduce cooling water. The oil-water mixture output after condensation by the condensation mechanism 30 will enter the separator housing 411 along the oil-water mixture inlet pipe 412, and the end of the oil-water mixture inlet pipe 412 The oil-water mixture extends into the vortex space formed by the vortex pipe 414, and the oil-water mixture can enter the vortex space along the oil-water mixture inlet pipe 412, and an electromagnetic separator 43 is also provided on the outside of the vortex pipe 414 in the separator shell 411. The electromagnetic separator 43 is used to generate high-voltage direct current to remove emulsification and promote oil-water separation of the oil-water mixture. The oil-water mixture that enters the separator shell 411 through the oil-water mixture inlet pipe 412 can complete oil-water separation under the dual action of the vortex cooler 413 and the electromagnetic separator 43, so that the essential oil and cooling water are stratified in the separator shell 411.

[0042] Finally, a cooling water outlet pipe 416 is provided at the bottom of the separator shell 411, which is used to guide the cooling water obtained after the oil-water mixture is separated from the separator shell 411, and then the Torreya aril essential oil is guided out through the light oil collector and essential oil delivery pipe provided at the top of the separator shell 411, thereby realizing the collection of Torreya aril essential oil.

[0043] In this embodiment, the operating principle of the device shown is: After the Torreya grandis arils contained in the mesh bag 11 are squeezed, the squeezed liquid derived from the Torreya grandis arils enters the distillation tank 21 through the liquid outlet channel 13 and the feed pipe 23. After high-temperature steam is introduced into the distillation tank 21, the essential oil volatile oil derived from the squeezed liquid follows the steam through the condensation conduit 33 and enters the condensation mechanism 30 for condensation treatment to obtain an oil-water mixture. The oil-water mixture enters the oil-water separation mechanism 40 through the separation conduit 42 for oil-water separation and essential oil extraction, and finally the Torreya grandis arils essential oil derived from the Torreya grandis arils is obtained.

[0044] In summary, compared with the prior art, the separation and extraction system of Torreya grandis aril essential oil described in this embodiment has the following beneficial effects: A pressing mechanism 10 is provided to press the Torreya grandis aril so as to output a pressed liquid, and a distillation mechanism 20 is provided to distill the pressed liquid so as to output essential oil volatiles and steam. Then, a condensation mechanism 30 is provided to condense the essential oil volatiles and steam so as to output an oil-water mixture. Finally, an oil-water separation mechanism 40 is used to separate and extract the oil-water separator so as to output condensed water and Torreya grandis aril essential oil derived from the Torreya grandis aril, respectively. Finally, the Torreya grandis aril essential oil is collected. In this embodiment, by providing the above-mentioned pressing mechanism 10, distillation mechanism 20, condensation mechanism 30 and oil-water separation mechanism 40, Torreya grandis aril essential oil can be produced quickly and efficiently. Moreover, the cost investment of the above-mentioned mechanisms is relatively small, and they are suitable for introduction into smaller-scale planting areas.

[0046] Specifically, the spray assembly 25 is provided with two groups, which are respectively arranged in the middle and the top of the distillation tank 21. The liquid nozzles 252 arranged on the liquid guide plate 251 are radially arranged on the liquid guide plate 251 to face the inner wall of the distillation tank 21, and the spray angle of the liquid nozzle 252 can be adjusted by adjusting the knob. Its function is to spray a small amount of cold water toward the tank wall surface above the liquid level in the distillation tank 21 during the distillation process, thereby solving the problem of the tank wall being burned by the squeezed liquid during the distillation process, and a large amount of spraying can be performed to clean the tank wall after the distillation is completed.
