Description

Technical Field

[0001] The invention relates to the technical field of essential oil extraction, in particular to a tangerine peel essential oil extraction device and an extraction method thereof. Background Art

[0002] There are many methods for extracting essential oils, including cold pressing, distillation, and oil immersion. Currently, tangerine peel essential oil is mainly extracted by distillation.

[0003] For example, a Chinese patent application with authorization publication number CN114854494B discloses an essential oil extractor, which improves the existing integrated extraction tank structure into a combined extraction tank structure. The combined extraction tank consists of a cylinder and a disassembly plate, which can be detachably connected and can rotate relative to each other after installation. As the disassembly plate rotates, the support plate in the cylinder is driven to vibrate vertically back and forth. At the same time, the disassembly plate is connected to the third gear ring, and the third gear ring rotates the drive disk through the power transmission of the bevel gear set, thereby prompting the swing arm to flip the material.

[0004] This patent uses a swing arm to give the material a turning force, and uses a vibration frame to make the material swing repeatedly, thereby increasing the contact between the steam and the material and improving the efficiency of essential oil extraction. However, when extracting tangerine peel essential oil, repeatedly moving the tangerine peel will cause damage to the surface of the tangerine peel, resulting in an increase in impurities after the essential oil is extracted. In addition, when the current essential oil extraction equipment extracts essential oils by distillation, after a batch of tangerine peel is extracted, it is necessary to remove the residue and add new tangerine peel. At this time, it is necessary to wait for the equipment to cool down, which affects efficiency and also causes heat loss, which is not energy-efficient. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a tangerine peel essential oil extraction device and an extraction method thereof, so as to increase the steam flow rate, improve the essential oil extraction efficiency, and quickly replace the tangerine peel raw material without waiting for the equipment to cool down, which is energy-saving and environmentally friendly.

DETAILED DESCRIPTION

[0032] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0033] Example 1

[0034] See also Figure 1 , Figure 2 and Figure 7As shown: a tangerine peel essential oil extraction device, including an insulation barrel 1, a tangerine peel container 2, a steam generator 3, a piston 4, a reciprocating screw rod 5, a driving mechanism 6 and a steam collecting pipe 8, the steam generator 3 and the steam collecting pipe 8 are both fixed in the insulation barrel 1 and located in the middle of the insulation barrel 1, and the tangerine peel container 2 is distributed around the steam generator 3, the tangerine peel container 2 is inserted in the insulation barrel 1, the end of the tangerine peel container 2 is sealed and connected to the insulation barrel 1, and the output part of the steam generator 3 is connected to the inside of the tangerine peel container 2; illustratively, the steam generator 3 is used to provide steam to the tangerine peel container 2, so that the tangerine peel is heated and separated into gaseous essential oil, and the gaseous essential oil is collected in the steam collecting pipe 8, and the top of the steam collecting pipe 8 needs to be connected to a condensing device to condense the gaseous essential oil into a liquid state. The specific structure and principle of the condensing device will not be elaborated in detail here;

[0035] For further information, see Figure 1 , Figure 2 and Figure 7 As shown, an end cap 22 is inserted and fixed on the top of the tangerine peel container 2, and a piston member 4 is slidably and sealedly connected in the end cap 22, and a reciprocating screw rod 5 is slidably connected in the middle of the piston member 4. Specifically, a convex block is fixed on the inner wall of the middle part of the piston member 4, and the convex block is slidably connected with the reciprocating spiral groove on the outer surface of the reciprocating screw rod 5. The convex block can be pushed by rotating the reciprocating screw rod 5. Since the piston member 4 can only slide up and down in the end cap 22, the convex block slides up and down along the reciprocating spiral groove, so that the piston member 4 moves as a piston in the end cap 22; the purpose is that through the piston movement of the piston member 4, the gas at the bottom of the tangerine peel container 2 can be accelerated to the top of the tangerine peel container 2, and the gas is accelerated to circulate among a pile of tangerine peels, so that a pile of tangerine peels are heated more evenly, thereby improving the extraction efficiency and quality of tangerine peel essential oil;

[0036] It is worth mentioning that a vent hole (not shown) is provided on the top of the end cover 22, through which air can flow, so that the piston member 4 can move normally in the end cover 22; the reciprocating screw rod 5 can be driven by a motor, and the reciprocating screw rod 5 can also be replaced by a cylinder.

[0037] For further information, see Figure 2 , Figure 3 and Figure 4 As shown, a first connecting valve 21 is fixed to the bottom of the tangerine peel container 2, an air guide pipe 31 is fixed to the top of the steam generator 3, a second connecting valve 32 is provided at one end of the air guide pipe 31 away from the steam generator 3, and the inner cavity of the steam generator 3 is communicated with the inner cavity of the tangerine peel container 2 through the air guide pipe 31, the second connecting valve 32 and the first connecting valve 21;

[0038] For details, see Figure 2 , Figure 3 and Figure 4As shown, the first connecting valve 21 includes a first valve cover 211, a first valve cylinder 212, a first valve core 213 and a first spring 214. The first valve cover 211 is fixedly connected to the bottom of the tangerine peel container 2. The upper surface of the first valve cover 211 is evenly provided with vent holes.

[0039] Exemplarily, after the tangerine peel container 2 is loaded into the insulation barrel 1, the first valve core 213 and the second valve core 323 are offset against each other, so that the first valve core 213 and the second valve core 323 are respectively retracted into the first valve cylinder 212 and the second valve cylinder 321. Since the first valve core 213 and the second valve core 323 are both designed with a conical structure, when the first valve core 213 and the second valve core 323 are respectively retracted into the first valve cylinder 212 and the second valve cylinder 321, a gap will appear between the first valve core 213 and the second valve core 323 and the first valve cylinder 212 and the second valve cylinder 321. At this time, it is equivalent to the valve opening state, and the steam generator 3 is connected to the tangerine peel container 2. Otherwise, the steam in the steam generator 3 will not leak out through the second connecting valve 32.

[0041] See also Figure 2 As shown, a one-way valve 81 is evenly fixed on the outer surface of the steam collecting pipe 8, and the steam collecting pipe 8 is connected to the tangerine peel container 2 through the one-way valve 81. The flow direction of the one-way valve 81 is from the tangerine peel container 2 to the steam collecting pipe 8; the purpose is that when a certain tangerine peel container 2 is drawn out, the steam in the steam collecting pipe 8 will not flow back, thereby ensuring the safety of replacing a new tangerine peel container 2.
