Description

Technical Field

[0001] The utility model belongs to the technical field of osmanthus processing and relates to an osmanthus essential oil adsorption type extraction device. Background Art

[0002] There are many ways to extract osmanthus essential oil, including solvent extraction, steam distillation, vacuum distillation adsorption, supercritical carbon dioxide extraction, activated carbon adsorption, etc. The activated carbon adsorption method is to heat the fresh osmanthus, and take advantage of the volatility of essential oil and water to temporarily store the essential oil and water in the osmanthus in the adsorbed carbon. Finally, the water vapor in the adsorbed carbon is separated. This is a way to purify the multiple components of osmanthus into two components.

[0003] At present, the activated carbon adsorption method directly adopts the volatilization method, which is less efficient and causes the osmanthus raw materials to be heated unevenly. Utility Model Content

The technical problem to be solved by the utility model is how to improve the extraction efficiency of osmanthus essential oil.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an osmanthus essential oil adsorption extraction device, characterized in that it includes a frame, a rotating drum and a hollow core tube, both ends of the core tube are fixed on the frame, the rotating drum is rotatably connected to the core tube, the rotating drum is driven by a motor, both ends of the core tube extend out of the rotating drum, one end of the core tube is the inlet of the activated carbon adsorption block, the other end of the core tube is the outlet of the activated carbon adsorption block, an air connection pipe is connected to the core tube near one end of the activated carbon adsorption block outlet, the middle section of the core tube is a mesh structure, and a heater located outside the rotating drum is fixedly provided on the frame.

[0007] Furthermore, a push rod is inserted at the inlet, and a gap is provided between the outer wall of the push rod and the inner wall of the core tube.

[0008] Furthermore, the outlet is detachably connected to a plug.

[0009] When operating, first open the baffle door, put the osmanthus raw material into the drum, close the baffle door, fill the core tube with activated carbon adsorption block, close the plug, pneumatic motor and heater, the drum rotates slowly, the material is evenly turned and heated in the drum, the air pipe is connected to the negative pressure air source, under the action of negative pressure, the air flow enters the drum from the inlet, and then enters the core tube from the inner cavity of the drum. After the activated carbon adsorption block is filtered, the air flow is extracted from the air pipe. In this way, the activated carbon adsorption block can be rotated without stopping the machine, that is, the pushing rod is pulled out, a new activated carbon adsorption block is filled, and the outlet is opened to take out the fully adsorbed activated carbon adsorption block.

[0010] In addition, since the drum rotates slowly, a certain number of metal balls can be filled in the drum. The metal balls can squeeze and break the material during the material turning process, thereby accelerating the volatilization of volatile substances in the material.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2 The osmanthus essential oil adsorption extraction device shown includes a frame 1, a rotating drum 2 and a hollow core tube 3. Both ends of the core tube 3 are fixed to the frame 1. The rotating drum 2 is rotatably connected to the core tube 3. The rotating drum 2 is driven by a motor 4. Both ends of the core tube 3 extend outside the rotating drum 2. One end of the core tube 3 is the inlet of the activated carbon adsorption block, and the other end of the core tube 3 is the outlet of the activated carbon adsorption block. An air receiving pipe 5 is connected to the core tube 3 near one end of the activated carbon adsorption block outlet. The middle section of the core tube 3 is a mesh structure. A heater 6 located outside the rotating drum 2 is fixedly provided on the frame 1.

[0016] The rotating drum 2 is provided with a material opening, and the material opening is detachably connected to a blocking door 7.

[0017] A push rod 8 is inserted at the inlet, and there is a gap between the outer wall of the push rod 8 and the inner wall of the core tube 3. A plug 9 is detachably connected to the outlet.

[0018] When operating, first open the baffle door 7, put the osmanthus raw material into the drum 2, close the baffle door 7, fill the core tube 3 with activated carbon adsorption blocks, close the plug 9, the pneumatic motor 4 and the heater 6, and the drum 2 rotates slowly. The material is evenly turned and heated in the drum 2. The air pipe 5 is connected to the negative pressure air source. Under the action of negative pressure, the air flow enters the drum 2 from the inlet and then enters the core tube 3 from the inner cavity of the drum 2. After the activated carbon adsorption block is filtered, the air flow is extracted from the air pipe 5. In this way, the activated carbon adsorption blocks can be rotated without stopping the machine, that is, the push rod 8 is pulled out, a new activated carbon adsorption block is filled, and the outlet is opened to take out the fully adsorbed activated carbon adsorption block.

[0019] In addition, since the drum 2 rotates slowly, a certain number of metal balls can be filled in the drum 2. The metal balls can squeeze and break the material during the material turning process, thereby accelerating the volatilization of volatile substances in the material.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
