Description

Technical Field

[0001] This utility model relates to the field of agarwood processing technology, specifically to an essential oil extraction device for agarwood processing. Background Technology

[0002] When mature Aquilaria sinensis or Aquilaria agallocha trees (family Thymelaeaceae) are damaged by external factors or develop diseases, they instinctively secrete resin to repair the wounds. During this process, if they happen to be infected by a fungus called *Aquilaria fulvidraco*, this fungus will undergo frenzied metabolism to survive within the tree, resulting in a series of remarkable chemical changes. The tree's own antibodies mix with the infected fungus over a long period, gradually forming a mixture of resin and wood fiber—aquilaria agallocha.

[0003] Currently, common extraction methods for agarwood essential oil include evaporation extraction, solvent extraction, and supercritical extraction. Solvent extraction leaves solvent residues, making the essential oil less pure. Supercritical extraction requires supercritical equipment, which is too expensive per unit. Evaporation extraction has the advantages of pure extraction and lower cost. However, it has disadvantages such as low efficiency in extracting essential oil from agarwood, such as agarwood accumulation and a single steam inlet location, which can easily form a central jet flow and result in insufficient steam in the peripheral areas. Therefore, we propose an essential oil extraction device for agarwood processing. Utility Model Content

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this utility model provides a technical solution: an essential oil extraction device for agarwood processing, comprising:

[0028] An evaporator 1 is provided, wherein an electric heating plate 109 is fixedly installed at the lower end of the inner cavity of the evaporator 1, a polyshell cover 101 is fixedly installed at the top of the evaporator 1, a gas guide pipe 102 is connected to the top of the polyshell cover 101, a cooling cylinder 103 is connected to the right end of the gas guide pipe 102, and a separation vessel 105 is provided at the bottom of the cooling cylinder 103.

[0029] PLC controller 4, which is fixedly installed on the upper right side of the evaporator 1;

[0030] The guide positioning seat 3 is fixedly installed on the upper end of the inner cavity of the evaporator 1 by connecting bolts 306, and an annular filter plate 302 is provided at the middle of the inner side of the guide positioning seat 3.

[0031] A support frame 104 is fixedly installed at the lower end of the outer surface of the cooling cylinder 103. A spiral tube 106 is provided in the inner cavity of the cooling cylinder 103, and both the upper and lower ends of the spiral tube 106 extend to the outside of the cooling cylinder 103. A maintenance sealing door 108 is provided on the rear side of the evaporator 1. A liquid injection pipe 107 is connected to the front of the evaporator 1, and a sealing cap is threaded to one end of the liquid injection pipe 107. A material sealing door 110 is provided at the upper end of the rear side of the polyshell cover 101. Guide inclined surfaces are provided at both the upper and lower ends of the guide positioning seat 3, and the interior of the guide positioning seat 3 is a hollow structure. A slot 301 is opened on the left side of the guide positioning seat 3.

[0032] This technical solution involves injecting clean water into the evaporator 1 through the injection pipe 107, then screwing on the sealing cap. After opening the material spreading sealing door 110, a 1-3cm layer can be evenly spread on the top of the annular filter plate 302. 3The blocky agarwood is removed to prevent it from piling up. Then, the material sealing door 110 is closed, and the electric heating plate 109 is powered on by the PLC controller 4. The steam generated after the water is heated can flow upward in the evaporation box 1. At this time, the inclined surface at the lower end of the guide positioning seat 3 can guide the steam away from the inner wall of the evaporation box 1 and move towards the center. The central guide can prevent the formation of a central jet flow and can guide the steam to diffuse outward, thereby guiding the steam to the bottom of the annular filter plate 302. After the steam passes through the annular filter plate 302, it can accelerate the mass transfer process of essential oil components from the solid to the vapor phase and avoid the situation of uneven heating of raw materials due to insufficient steam in the edge area. After the steam enters the cooling cylinder 103 through the air guide pipe 102, the cooling water is introduced into the spiral tube 106, and the cooled steam liquid is introduced into the separator 105 for collection, which is beneficial to people's use.

[0033] Example 2

[0034] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a drive motor 2 is fixedly installed on the upper left side of the evaporator 1. The drive motor 2 is a forward and reverse motor. A drive gear 201 is fixedly installed on the output end of the drive motor 2. A cross-shaped limiting plate 307 is provided on the upper end of the guide positioning seat 3. A rotating plate 303 is fixedly connected to the top of the cross-shaped limiting plate 307. A toothed ring 308 located in the inner cavity of the guide positioning seat 3 is fixedly connected to the bottom of the cross-shaped limiting plate 307. The toothed ring 308 meshes with the drive gear 201. A plurality of equidistantly distributed connecting plates 304 are fixedly connected to the top of the rotating plate 303. A stirring rod 305 is fixedly connected to the bottom of the connecting plate 304.

[0035] This technical solution: First, the PLC controller 4 sets the speed, forward rotation time, reverse rotation time, and pause time of the drive motor 2. For example, setting the speed of the drive motor 2 to 90-140 rpm, forward rotation for 3 minutes, reverse rotation for 3 minutes, and pause for 10 minutes, the drive motor 2 can drive the drive gear 201 to rotate at 90-140 rpm. With the assistance of the meshing gear ring 308, and through the setting of the meshing ratio, the speed of the gear ring 308 can be between 6-14 rpm. When the gear ring 308 rotates, it can drive the connecting plate 304 and the stirring rod 305 to rotate through the cross limit plate 307 and the rotating plate 303. When the stirring rod 305 rotates, it can turn over the laid block agarwood. After the gear ring 308 rotates for three minutes, the drive motor 2... The drive gear 201 will rotate in the opposite direction for three minutes, which will cause the stirring rod 305 to turn the blocky agarwood in the opposite direction. After three minutes, the drive motor 2 will stop working for ten minutes, and then the same process will be repeated. The added turning structure of this equipment can break the dead volume formed by the accumulation of raw materials, so that the inner layer of raw materials that were originally wrapped will be continuously exposed to steam, avoiding local essential oil residue. It can also prevent the "channel flow" phenomenon caused by the accumulation of particles, making the steam distribution more uniform. Furthermore, the turning can prevent the raw materials from decomposing due to local overheating (such as near the heating source), and at the same time accelerate the transfer of heat from the heating surface to the inside of the raw materials. It can also slightly squeeze or break some blocky raw materials, destroy the cell structure, and accelerate the release of essential oil.

[0036] It should be noted that the PLC controller 4 and drive motor 2 used in this equipment can be purchased directly from the market. At the same time, the connection methods and electrical connections of each component adopt mature and conventional methods in existing technology, so they will not be described in detail here.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
