Description

Technical Field

[0001] The present application relates to the technical field of extraction equipment, and in particular to an extraction tank for grape seed shell powder. Background Art

[0002] The main component of grape seed extract is proanthocyanidins, currently the most powerful water-soluble antioxidant among natural products. They effectively scavenge free radicals and have strong anti-aging, beauty, and immunity-boosting properties. Proanthocyanidins are primarily found in the grape seed shell, but extracting them from the inner shell is difficult when using the whole grape seed as the raw material. To improve extraction efficiency, the grape seed is typically separated from the kernel and then ground into a powder.

[0003] In existing technology, proanthocyanidins are typically extracted using an extraction tank equipped with rotating stirring blades. The specific extraction process involves pouring powdered grape seed shell material and extract into the tank sequentially, then activating the stirring blades to mix the material and extract. In current factory production, to extract large quantities of proanthocyanidins at once, the grape seed extraction tanks are typically built to a depth of over 5 meters.

[0004] In the aforementioned technologies, the material and extract are typically concentrated at the bottom of the extraction tank, which typically features a rotating clamshell structure. Commercially available agitator shafts extend downward from the top of the tank, resulting in a deep depth within the extraction tube. This places high demands on the shaft's rigidity and strength. Furthermore, the agitator blades at the bottom are subject to significant torque, making them susceptible to breakage. Utility Model Content

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses an extraction tank for grape seed shell powder.

[0039] Reference Figure 1 , an extraction tank for grape seed shell powder, comprising an extraction tank body 1 for mixing materials and extracting liquid and a filter 2 for filtering the extracting liquid.

[0040] The extraction tank 1 is a vertically arranged cylindrical tank with a material inlet 11 at its top for pouring material. A feed pipe 12 is also provided on one side of the material inlet 11. One end of the feed pipe 12 extends into the extraction tank 1 and the other end is connected to a tank storing the extract. The extract is delivered to the extraction tank 1 by a pump.

[0041] The bottom of the extraction tank 1 has a material discharge hole 13 and a rotating lid 3 for covering the discharge hole 13. The rotating lid 3 is a circular cover plate with a hinged rod 31 on the side facing away from the extraction tank 1. A hinged seat 14 is fixed to the bottom outer wall of the extraction tank 1, which engages with the hinged rod 31. In this embodiment, the hinged rod 31 rotates by driving an oil cylinder. To enhance the stability of the rotating lid 3 and the extraction tank 1, a locking assembly 15 is also provided at the bottom of the extraction tank 1 for locking the rotating lid 3.

[0042] Reference Figure 1 and Figure 2The locking assembly 15 includes a locking ring 151 rotatably mounted on the bottom of the extraction tank 1 and a locking driver 152 that drives the locking ring 151 to rotate. The inner diameter of the locking ring 151 is larger than the outer diameter of the rotating cover 3. A plurality of locking blocks 1511 are circumferentially arranged on the inner bottom wall of the locking ring 151 along the axis of the extraction tank 1. The locking blocks 1511 are integrally formed with the locking ring 151, and insertion slots 1512 are formed between adjacent locking blocks 1511.

[0043] The outer wall of the rotating cover 3 is circumferentially provided with locking blocks 32 corresponding one-to-one with the insertion slots 1512. The insertion slots 1512 and the locking blocks 32 are of matching size. When the rotating cover 3 is rotated to a horizontal state under the action of the oil cylinder, the locking blocks 32 are inserted into the insertion slots 1512. At this time, the locking blocks 32 are located above the locking blocks 1511 in the vertical direction. The locking drive 152 is activated, and the locking ring 151 rotates horizontally along the axis of the extraction tank body 1. The rotation stops after the locking blocks 1511 and the locking blocks 32 are aligned in the vertical direction. The locking blocks 1511 support and lock the locking blocks 32, thereby improving the connection stability between the rotating cover 3 and the extraction tank body 1.

[0044] Reference Figure 1 and Figure 3 The extraction tank body 1 is provided with a stirring mechanism 16 for stirring the material and the extract. The stirring mechanism 16 includes a steam pipe 161 passing through the top of the extraction tank body 1, a steam joint 162 provided at the end of the steam pipe 161, and a submerged mixer 163 fixed to the inner wall of the extraction tank body 1.

[0045] The steam pipe 161 is coaxially arranged with the axis of the extraction tank body 1, and its length is approximately three-quarters of the extraction tank body 1, so that after the material and the extract are poured in, the mixed liquid surface of the two substances can submerge the steam joint 162. The steam pipe 161 is connected to the high-pressure steam at the top outside the extraction tank body 1, and the steam pipe 161 is fixedly connected to the steam joint 162 at the bottom inside the extraction tank body 1. The top of the steam joint 162 is connected to the steam pipe 161, and the bottom has at least two steam outlets. The steam outlet and the output direction are perpendicular to the axis of the steam pipe 161, so that the high-temperature steam can better stir the extract. In this embodiment, the steam joint 162 has two steam outlets symmetrical along the axis.

[0046] The submersible mixers 163 have the same structure as conventional submersible propellers. Their power cords extend from the top plate of the extraction tank 1 to the outside. A mounting plate 164 for the submersible mixers 163 is fixed to the inner wall of the extraction tank 1. Multiple mounting plates 164 are evenly spaced along the axis of the extraction tank 1. The output shafts of the submersible mixers 163 are arranged horizontally, forming a circular circulation loop. Multiple submersible mixers 163 are used to achieve mixing of the liquid mixture.

[0047] The side of the rotating cover 3 facing the extraction tank body 1 has a storage chamber 33. The storage chamber 33 is a conical cavity with its apex facing downward. The outer wall of the rotating cover 3 has a first delivery pipe 34 connected to the storage chamber 33. The axis of the first delivery pipe 34 is coaxial with the storage chamber 33. The top of the storage chamber 33 is provided with a filter plate 35 and a first screen 36 in the vertical direction from low to high. The filter plate 35 is a metal plate fixed to the rotating cover 3. The filter plate 35 is evenly provided with flow holes 351 for the extraction liquid to flow into the storage chamber 33. The first screen 36 is fixed to the top of the filter plate 35 by a metal ring frame. The mesh of the first screen 36 is smaller than the mesh of the flow hole 351, so as to reduce the probability of material entering the storage chamber 33 and causing blockage.

[0048] In order to adapt to the rotation of the rotating cover 3 , the first delivery pipe 34 is a metal hose with deformation capability. One end of the first delivery pipe 34 away from the rotating cover 3 is connected to the filter 2 .

[0049] The inner wall of the extraction tank body 1 is also provided with a second extraction member 4 for collecting the extraction liquid. The second extraction member 4 includes a second collecting tube 41 and a second delivery tube 42 provided at the end of the second collecting tube 41. The second collecting tube 41 is a vertically arranged circular tube, and its entirety is located on the bottom inner wall of the extraction tank body 1. The second collecting tube 41 is evenly provided with flow holes 351 for the extraction liquid to flow in. In order to reduce the material from entering the second delivery tube 42, a second screen 43 for blocking the material is also provided on the outside of the second collecting tube 41. The second screen 43 is annular and has sieve holes of the same size as the first screen 36. A valve body for controlling liquid delivery is installed on both collection tubes.

[0050] Reference Figure 1 and Figure 4 The other end of the second delivery pipe 42 is connected to a recovery pipe 44, and the first delivery pipe 34 is also connected to the recovery pipe 44. The output end of the recovery pipe 44 is connected to the filter 2. In this embodiment, the output end of the recovery pipe 44 is divided into two filters 2. The output ends of the two filters 2 are reunited and are provided with a circulation pipe 45 connected to the top of the extraction tank body 1. The filtered extract is returned to the extraction tank body 1 by driving the pump body 46, realizing the recycling of the extract.

[0051] Reference Figure 3 and Figure 5 The outer wall of the extraction tank 1 is sequentially covered with a heating layer 5 and an insulation layer 6. A heating chamber is formed between the heating layer 5 and the outer wall of the extraction tank 1. A steam inlet pipe 51 is provided on the heating layer 5, connecting to the heating chamber. The other end of the steam inlet pipe 51 is connected to a device that generates high-temperature steam. The heating layer 5 heats the extraction tank 1, thereby improving extraction efficiency.

[0052] The insulation layer 6 is filled with insulation material, which may be rock wool, glass wool, polystyrene board, silicate board, etc. The insulation layer 6 stabilizes the temperature of the heating layer 5 and reduces energy consumption.

[0053] The present application also includes a cooling assembly 7 for maintaining the temperature inside the extraction tank 1. The cooling assembly 7 includes a condenser 71, a first cooling pipe 72, and a second cooling pipe 73. The extraction tank 1 is longer than 5 meters and spans two floors in the production plant. The condenser 71 is located on the top floor of the extraction tank 1.

[0054] A first cooling pipe 72 and a second cooling pipe 73 respectively connect the output and input ends of condenser 71. The other ends of both cooling pipes are connected to the top of extraction tank 1. When the temperature inside extraction tank 1 exceeds the required extraction temperature, the high-temperature gas is transported to the input end of condenser 71 via second cooling pipe 73. After cooling in condenser 71, the high-temperature gas is then transported to extraction tank 1 via first cooling pipe 72. To ensure the direction of gas flow, both cooling pipes are equipped with one-way valves.

[0055] A cleaning pipe 17 is also installed on the outside of the top of the extraction tank body 1. One end of the cleaning pipe 17 corresponds to the material port 11, and the other end is connected to the clean water source. The clean water is transported to the cleaning pipe 17 through the pump body and finally sprayed out from the end of the cleaning pipe 17 to flush the inner wall of the extraction tank body 1.

[0056] The working principle of the grape seed shell powder extraction tank according to the embodiment of the present application is as follows: the cover 3 is rotated to cover the feed hole 13 and locked by the locking assembly 15. High-temperature steam is input to the heating layer 5 to heat the extraction tank body 1. The extraction liquid and the material are poured into the extraction tank body 1 in sequence. After the liquid level of the extraction liquid submersible mixer 163 is submerged, the submersible mixer 163 is started to stir the mixed liquid.

[0057] Then, high-pressure steam is input into the steam pipe 161 to stir the central axis area of ​​the extract; after the stirring is completed, the valve bodies of the first delivery pipe 34 and the second delivery pipe 42 are opened, and the mixed liquid is transported to the filter 2 to filter out the proanthocyanidins. After that, the extract is input into the extraction tank 1 through the recovery pipe 44 and the drive pump body 46, and the above operation is repeated for secondary extraction;

[0058] During the extraction process, the temperature inside the extraction tank body 1 is detected by a temperature detector. When the temperature is high, the cooling component 7 is started to cool the temperature inside the extraction tank body 1.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
