Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic extraction tank technology, specifically relating to a low-temperature ultrasonic extraction tank for edible fungi. Background Technology

[0002] The low-temperature ultrasonic extraction vessel combines ultrasonic technology with low-temperature extraction, offering a highly efficient, low-temperature, and pollution-free extraction process. Its principle relies on mechanical vibration, cavitation effects, and the protection provided by low-temperature conditions. Existing ultrasonic extraction vessels simply add the extract and water into the vessel and then use an ultrasonic generator for extraction. Since both the extract and the ultrasonic generator are stationary, some extract will sink to the bottom near the vessel body. Because the distance between the extract and the ultrasonic generator varies at different locations, and because ultrasonic waves gradually attenuate during transmission in water, it cannot be guaranteed that all extracts will be fully extracted. Therefore, a low-temperature ultrasonic extraction vessel for edible fungi needs to be designed to address these problems. Utility Model Content

[0003] This invention provides a low-temperature ultrasonic extraction tank for edible fungi. Through the high-speed rotation of the blades, the extract and water are drawn in from the bottom of the tank and lifted into the drainage hood to be fully extracted by the ultrasonic generator. Under the action of centrifugal force, they are continuously thrown out and flow back to the bottom of the tank after being ejected from the drainage hole.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] A low-temperature ultrasonic extraction tank for edible fungi includes a tank body and an ultrasonic transmitter located inside the tank body. The tank body is also equipped with a flow guide hood that is located around the ultrasonic transmitter and has hollow openings at the top and bottom. The bottom of the flow guide hood is spaced apart from the inner bottom wall of the tank body. A flow guide component for directing the liquid at the bottom of the tank body to flow upward is also installed at the bottom of the tank body. The ultrasonic transmitter is located above the flow guide component.

[0006] Preferably, a drainage hole is provided on the side wall of the drainage hood at a position higher than the drainage component.

[0007] Preferably, a motor is provided below the tank body, and a rotating shaft is provided at the output end of the motor. The rotating shaft extends to the side wall inside the tank body and is provided with blades.

[0008] Preferably, a connecting rod is provided above the tank body, and an ultrasonic transmitter is fixedly connected to the lower end of the connecting rod. The ultrasonic transmitter extends through the connecting rod into the interior of the flow guide hood and is located above the flow guide assembly.

[0009] Preferably, the drainage cover is fixedly connected to the inner wall of the tank via a fixing column.

[0010] Preferably, the rotating shaft is connected to the tank body in a sealed rotation via a bearing.

[0011] The beneficial effects of this invention are: through the high-speed rotation of the blade, the extract and water are drawn in from the bottom of the tank and lifted into the drainage hood to be fully extracted by the ultrasonic generator. Under the action of centrifugal force, they are continuously thrown out and flow back to the bottom of the tank after being ejected from the drainage hole. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0020] The existing low-temperature ultrasonic extraction tank for edible fungi mainly includes a tank body 1 for holding the extract and extractant, and an ultrasonic transmitter 10 for emitting ultrasonic waves to generate cavitation effect and mechanical vibration, causing the target effective components in the extract to be released. During the extraction of the effective components, it ensures that the extract and extractant are extracted at low temperatures, thus having a better extraction effect on some target effective components that are easily denatured at high temperatures. In use, open the sealing cap 2 of the feed inlet 16 on the tank body 1, and add the extractant (most often water, but may also be other forms of extractant such as ethanol or other organic solvents) and extractant into the tank body 1 through the feed inlet 16. The liquid level of the extractant should be at least higher than the height of the ultrasonic transmitter 10. Then, seal the feed inlet 16 with the sealing cap 2. Subsequently, power is supplied to the ultrasonic transmitter 10 through the controller 3 to carry out the ultrasonic extraction process. The target effective components of the extract are precipitated and fused with the extractant under the action of ultrasound. After a certain period of time, open the valve 6 on the discharge pipe 5 at the bottom of the tank body 1 to discharge the material. Some ultrasonic generators 10 are often suspended in a fixed position inside the tank 1 by a connecting rod 15. After emitting ultrasonic waves, the ultrasonic waves diffuse evenly around the ultrasonic generator 10 as the center. When the diffused ultrasonic waves are transmitted to the extract, the ultrasonic waves act on the extract, causing its effective components to be released. The above is an introduction to the existing low-temperature ultrasonic extraction tanks for edible fungi. The problem with the existing low-temperature ultrasonic extraction tanks is that, since the ultrasonic generator 10 is fixed, the ultrasonic waves it generates gradually attenuate when propagating in the liquid. Therefore, the ultrasonic energy received by the extracts at different distances from the ultrasonic generator 10 is also different. For example, the density of shiitake mushroom fruiting bodies changes after mixing with water. Some shiitake mushroom fruiting bodies, because their density is greater than that of water, may sink to the bottom and move away from the ultrasonic generator 10. The extracts that are farther away from the ultrasonic generator receive lower ultrasonic energy, resulting in insufficient extraction. Therefore, the existing low-temperature ultrasonic extraction tanks for edible fungi often cannot guarantee that all extracts inside can be fully extracted of their effective components.

[0021] The present invention adopts the following improvement method to solve the problem.

[0022] like Figure 1-5As shown, this utility model provides a low-temperature ultrasonic extraction tank for edible fungi, including a tank body 1 and an ultrasonic transmitter 10 inside the tank body 1. Inside the tank body 1, a flow guide hood 9 is also provided, located around the ultrasonic transmitter 10 and having an open top and bottom with a hollow interior. The bottom of the flow guide hood 9 is spaced from the inner bottom wall of the tank body 1. A flow guide assembly is also installed at the bottom of the tank body 1 to direct the liquid at the bottom upwards. The ultrasonic transmitter 10 is located above the flow guide assembly. The present utility model is similar to the existing low-temperature ultrasonic extraction tanks for edible fungi in that it includes a tank body 1, an inlet 16, a sealing cap 2, a connecting rod 15, an ultrasonic transmitter 10, a controller 3, a discharge pipe, and a valve 6. The difference lies in the addition of the flow guide hood 9 and the flow guide assembly. By setting the flow guide hood 9 and the flow guide assembly, extracts with a density greater than water and sinking to the bottom can be drawn in and lifted by the flow guide assembly to the inside of the flow guide hood 9, close to the ultrasonic transmitter 10, so that the extracts are fully extracted and precipitated by the ultrasonic transmitter 10.

[0023] Furthermore, such as Figure 3-4 As shown, a drainage hole 18 is provided on the side wall of the drainage hood 9, above the position of the flow guiding assembly. Based on the above scheme, by providing a drainage hole 18 on the side wall of the drainage hood 9, the increased liquid level inside the drainage hood 9 can be discharged into the internal space of the drainage hood 9 in a timely manner through the drainage hole 18, thereby realizing a circulating liquid directional flow path (such as...). Figure 4 (As indicated by the arrow direction of the L-line in the middle), see reference. Figure 4 When the drainage component is working, the liquid surface at the bottom of the tank 1 moves upward against gravity under the action of the drainage component. After contacting the ultrasonic transmitter 10, it is discharged from the drainage hood 9 through the drainage hole 18 and then falls back to the bottom of the tank 1. This cycle continues. During the flow of the extract, the extract in the extract enters the interior of the drainage hood 9 synchronously, thereby avoiding the extraction of the extract that sinks to the bottom of the tank 1 from being too far away from the ultrasonic transmitter 10, which would result in insufficient extraction.

[0024] Furthermore, such as Figure 3 As shown, a motor 7 is located below the tank 1, and a rotating shaft 8 is located at the output end of the motor 7. A blade 11 is mounted on the side wall inside the tank 1, extending from the rotating shaft 8. During operation, the motor 7 drives the blade 11 on the side wall inside the tank 1 to rotate. The rotation of the blade 11 creates a negative pressure, lifting the extract and water located at the bottom of the tank 1. The rotating blade 11 also lifts nearby extracts (such as...) Figure 4 The G in the middle indicates that the extract is crushed. The crushed extract (extract with a diameter smaller than the drainage hole 18) is thrown out by the centrifugal force generated when the blade 11 rotates. It is ejected through the drainage hole 18 into the space between the outer wall of the drainage hood 9 and the inner wall of the tank 1. The extract with a diameter larger than the drainage hole 18 repeats the crushing process.

[0025] Furthermore, such as Figure 3-5 As shown, a connecting rod 15 is provided above the tank body 1, and an ultrasonic transmitter 10 is fixedly connected to the lower end of the connecting rod 15. The ultrasonic transmitter 10 extends into the inside of the flow guide hood 9 through the connecting rod 15 and is located above the flow guide assembly. By setting the connecting rod 15 to fix the ultrasonic transmitter 10, it is stabilized in a fixed position inside the tank body 1.

[0026] Furthermore, such as Figure 3-4 As shown, the drainage hood 9 is fixedly connected to the inner wall of the tank 1 by the fixing column 13. During operation, by setting the fixing column 13, the drainage hood 9 can support the tank 1 under the action of the fixing column 13, so that the drainage hood 9 is fixed inside the tank 1.

[0027] Furthermore, such as Figure 3-4 As shown, the rotating shaft 8 is connected to the tank body 1 in a sealed rotational manner through the bearing 14. During operation, the bearing 14 is set to form a sealed rotational connection between the rotating shaft 8 and the tank body 1 under the action of the bearing 14 (the bearing 14 is an existing sealed bearing 14, which has been used in the prior art, and its detailed structure will not be further described here).
