Description

Technical Field

[0001] This utility model relates to the field of essential oil extraction technology, and in particular to a plant essential oil extraction device with uniform heating. Background Technology

[0002] Plant essential oils are widely used in pharmaceutical, food, agriculture, cosmetic, and chemical industries due to their important physiological functions such as antibacterial, anti-inflammatory, anti-cancer, antioxidant, and cell metabolism and regeneration promotion. In the extraction process of plant essential oils, the distillation part is usually carried out by co-aqueous distillation in a round-bottom flask. During distillation, a sufficient amount of water needs to be added to submerge the plant raw material, which reduces heating efficiency and increases energy consumption. At the same time, the small mouth of the round-bottom flask is not conducive to loading and unloading.

[0003] The prior art CN217628288U discloses a plant essential oil extraction device. By setting the distillation flask to include a spherical heating chamber and a cylindrical storage chamber, it satisfies the heating effect while increasing the material holding space and realizing the effect of water distillation. Compared with the traditional co-water distillation, it improves the heating efficiency. By opening the top of the storage chamber, it is easy to put in and take out the material. The distillation cap and the distillation flask are detachably fixed by a retaining ring with a strip-shaped notch and the upper and lower positioning strips.

[0004] However, when the above-mentioned essential oil extraction device is in use, the material is directly heated by water vapor in the tank. During heating, the material is prone to accumulating, and the overall heating is slow and uneven, resulting in low utilization efficiency of raw materials and long distillation time. Utility Model Content

[0005] The purpose of this invention is to provide a plant essential oil extraction device with uniform heating, which aims to solve the technical problems of existing essential oil extraction devices where the material is directly heated by water vapor in the tank, the material is prone to accumulation during heating, the overall heating is slow and uneven, resulting in low utilization efficiency of raw materials and long distillation time.

[0006] To achieve the above objectives, this utility model provides a plant essential oil extraction device with uniform heating, including a distiller and a support column. The support column is disposed below the distiller. The device also includes a cover, a limiting mechanism, a condenser, a heating layer, a stirring mechanism, and a discharge pipe. The cover is detachably connected to the distiller and is located on the distiller. The limiting mechanism is used to limit and fix the cover on the distiller. The condenser is connected to the distiller via a transmission pipe. The heating layer is disposed inside the distiller. The stirring mechanism is used to stir the plant material inside the distiller to uniformly heat the plant material. The discharge pipe is connected to the distiller and is located outside the distiller.

[0007] The limiting mechanism includes a first connecting plate, a second connecting plate, and a limiting member. The first connecting plate and the second connecting plate are respectively disposed outside the distiller and the cover, and the first connecting plate and the second connecting plate are connected by the limiting member.

[0008] The limiting component includes a limiting bolt and a limiting nut. The limiting bolt is detachably connected to the first connecting plate and the second connecting plate, and passes through the first connecting plate and the second connecting plate, respectively. The limiting nut is detachably connected to the limiting bolt and is sleeved on the limiting bolt.

[0009] The stirring mechanism includes a stirring section and stirring blades. The stirring section is located below the distiller, and the output shaft of the stirring section passes through the distiller. Several stirring blades are evenly distributed outside the stirring section, and all the stirring blades are located inside the distiller.

[0010] The stirring blade includes a blade body and a steering plate. The blade body is disposed outside the stirring part, and the steering plate is rotatably disposed below each blade body.

[0011] This utility model discloses a uniformly heated plant essential oil extraction device. Plant materials are poured into a distiller, and a cover plate is placed on top. A limiting mechanism secures the cover plate above the distiller, sealing it off. The heating layer then heats the plant materials within the distiller, while a stirring mechanism simultaneously agitates them. This ensures uniform heating of the plant materials, accelerating the distillation rate and shortening the distillation time. This invention solves the technical problems of existing essential oil extraction devices where materials are directly heated by steam within the container, leading to material accumulation, slow and uneven heating, low utilization efficiency, and long distillation times.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] First Embodiment

[0018] Please see Figures 1-2 , Figure 1 This is a schematic diagram of the overall structure of the uniformly heated plant essential oil extraction device according to the first embodiment of this utility model. Figure 2 This is a cross-sectional view along the stirring section 111 of the uniformly heated plant essential oil extraction device according to the first embodiment of this utility model.

[0019] This utility model provides a plant essential oil extraction device with uniform heating: it includes a distiller 101, a support column 102, a cover 103, a limiting mechanism, a condenser 104, a heating layer 105, a stirring mechanism, and a discharge pipe 106. The limiting mechanism includes a first connecting plate 107, a second connecting plate 108, and a limiting member, which includes a limiting bolt 109 and a limiting nut 110. The stirring mechanism includes a stirring section 111 and stirring blades, and the stirring blades include a blade body 112 and a deflector plate 113. This solution solves the problems of the aforementioned essential oil extraction device, where the material is directly heated by steam in the tank, leading to material accumulation, slow and uneven heating, low raw material utilization efficiency, and long distillation time. Therefore, this solution can be used in the extraction of plant essential oils.

[0020] In this embodiment, by pouring the plant material into the distiller 101 and placing the cover plate on the distiller 101, the cover 103 is fixed above the distiller 101 by the limiting mechanism, thus sealing the distiller 101. Then, the plant material in the distiller 101 is heated by the heating layer 105, and at the same time, the plant material in the distiller 101 is stirred by the stirring mechanism, so that the plant material in the distiller 101 can be heated evenly, thereby accelerating the distillation rate of the plant material and shortening the distillation time. This solves the technical problem of existing essential oil extraction devices where the material is directly heated by water vapor in the tank, which easily causes the material to accumulate during heating, resulting in slow and uneven heating, low utilization efficiency of the raw material, and long distillation time.

[0021] The support column 102 is located below the distiller 101. The cover 103 is detachably connected to the distiller 101 and is located on the distiller 101. The limiting mechanism is used to limit and fix the cover 103 on the distiller 101. The condenser 104 is connected to the distiller 101 through a transmission pipe 114. The heating layer 105 is disposed inside the distiller 101. The stirring mechanism is used to stir the plant material inside the distiller 101 to uniformly heat the plant material. The discharge pipe 106 is connected to... The distiller 101 is connected and located outside the distiller 101. The discharge pipe 106 has a valve 115, which controls the opening or closing of the discharge pipe 106. Four support columns 102 are evenly distributed in a ring below the distiller 101, allowing the support columns 102 to support the distiller 101. The cover 103 is fixed to the distiller 101 by the limiting mechanism, allowing the cover 103 to seal the internal space of the distiller 101. The body 103 has a protruding plate 116, and the distiller 101 has a groove 117. The protruding plate 116 cooperates with the groove 117 and can be inserted into the groove 117. Thus, the cooperation of the protruding plate 116 and the groove 117 seals the gap between the cover plate and the distiller 101, preventing the vapor distilled from the plant material from leaking out during distillation. The distiller 101 is cylindrical, and the heating layer 105 is uniformly arranged in a ring shape within the distiller. Inside the still 101, the heating layer 105 can uniformly heat the plant material inside the still 101. After heating, the generated steam can be transferred to the condenser 104 for condensation via the transmission pipe 114. After the plant essential oil extraction is completed, the valve 115 controls the opening or closing of the discharge pipe 106. After the through hole of the discharge pipe 106 is opened, the discharge pipe 106 is connected to the still 101, so that the residue after distillation can be discharged from the discharge pipe 106 to the outside of the still 101.

[0022] Secondly, the first connecting plate 107 and the second connecting plate 108 are respectively disposed outside the distiller 101 and the cover 103. The first connecting plate 107 and the second connecting plate 108 are connected by the limiting member. By connecting the first connecting plate 107 and the second connecting plate 108 together, the cover can be connected to the distiller 101.

[0023] Furthermore, the limiting bolt 109 is detachably connected to the first connecting plate 107 and the second connecting plate 108 respectively, and passes through the first connecting plate 107 and the second connecting plate 108 respectively. The limiting nut 110 is detachably connected to the limiting bolt 109 and is sleeved on the limiting bolt 109. The first connecting plate 107 and the second connecting plate 108 both have through holes. The limiting bolt 109 passes through the through holes of the first connecting plate 107 and the second connecting plate 108 respectively. The limiting bolt 109 has external threads, and the limiting nut 110 has internal threads. The internal thread of the limiting nut 110 cooperates with the external thread of the limiting bolt 109, so that the limiting nut 110 can move along the thread trajectory outside the limiting bolt 109, thereby allowing the first connecting plate 107 to be connected to the second connecting plate 108.

[0024] In addition, the stirring part 111 is disposed below the distiller 101, the output shaft of the stirring part 111 passes through the distiller 101, and a plurality of stirring blades are evenly distributed outside the stirring part 111, and all the stirring blades are located inside the distiller 101.

[0025] Finally, the blade body 112 is disposed outside the stirring section 111, and a steering plate 113 is rotatably disposed below each blade body 112. When the stirring section 111 is started, the output shaft of the stirring section 111 will rotate along the axis of the output shaft of the stirring section 111, driving the blade body 112 to rotate within the still 101 along the axis of the output shaft of the stirring section 111. This, in turn, drives the steering plate 113 to rotate within the still 101 along the axis of the output shaft of the stirring section 111. While the steering plate 113 rotates within the still 101 along the axis of the output shaft of the stirring section 111, the steering plate 113 is subjected to rotational force, causing it to rotate within the still 101 along the rod of the blade body 112. This allows the plant material accumulated within the still 101 to be lifted up, thereby accelerating the stirring rate of the plant material within the still 101.

[0026] When using this utility model, the pulverized plant material is poured into the distiller 101, and then the cover plate is placed on the distiller 101, aligning the through hole of the first connecting plate 107 with the through hole of the second connecting plate 108. Next, the limiting bolt 109 is inserted into the through holes of the first connecting plate 107 and the second connecting plate 108, and then passes through them. The limiting nut 110 is then screwed onto the limiting bolt 109, allowing the limiting nut 110 to move along the thread track outside the limiting bolt 109, so that the first connecting plate 107 can be connected to the second connecting plate 108, thereby connecting the cover plate to the distiller 101 and thus fixing the cover plate to the distiller 101, achieving the sealing of the distiller 101.

[0027] Subsequently, the heating layer 105 is activated to heat the plant material inside the still 101. Simultaneously, the stirring unit 111 is activated, causing its output shaft to rotate along its axis. This rotation drives the blades 112 to rotate within the still 101 along the same axis, which in turn drives the steering plate 113 to rotate within the still 101 along the same axis. While the steering plate 113 rotates within the still 101 along the same axis,… Because the steering plate 113 is subjected to rotational force, it can rotate along the rod of the blade body 112 within the still 101. This allows the plant material accumulated within the still 101 to be lifted, thereby accelerating the stirring rate of the plant material within the still 101. Consequently, the plant material within the still 101 can be heated evenly, thus accelerating the distillation rate and shortening the distillation time. This solves the technical problem in existing essential oil extraction devices where the material is directly heated by steam in the tank, leading to material accumulation, slow and uneven heating, low utilization efficiency of the raw material, and long distillation time.

[0028] During the uniform heating of the plant raw materials, the generated steam rises continuously and is transmitted to the condenser 104 through the transmission pipe 114, where the steam is condensed, thereby enabling the extraction of plant essential oils from the plant raw materials. After the plant essential oil extraction is completed, the valve 115 controls the opening or closing of the discharge pipe 106. When the through hole of the discharge pipe 106 is opened, the discharge pipe 106 is connected to the distiller 101, allowing the residue after distillation to be discharged from the discharge pipe 106 to the outside of the distiller 101.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
