Description

Technical Field

[0001] This application relates to the field of production, and in particular to a highly efficient extraction and reconstitution apparatus for producing black goji berry beverages. Background Technology

[0002] Black goji berries are the best raw material for extracting anthocyanins and are known as the "King of Anthocyanins." Proanthocyanidins are one of the important active ingredients in black goji berries, possessing high economic value and market demand. In the processing of black goji berry beverages, fresh or dried black goji berries are used as raw materials. Because fresh black goji berries require relatively strict storage conditions, it is more common to process them into beverages using dried black goji berries.

[0003] Black goji berry extract is produced on a large scale and industrially based basis using water or ethanol as the main solvent. The production process involves cleaning and chopping the raw material, soaking it in an extraction tank for 3 hours, followed by three extractions, filtration, concentration, and spray drying into a fine powder. The powder is then reconstituted by adding appropriate amounts of water and other excipients in a specific ratio to fully dissolve the extract. Further adjustments can be made according to product requirements, such as adjusting the taste or adding other nutrients, ultimately producing a black goji berry beverage. In the production of black goji berry beverages, an efficient extraction and reconstitution device is crucial for fully extracting and reconstituted the effective components from the black goji berries.

[0004] Regarding the aforementioned technologies, the inventors believe that they have the following drawbacks: low time efficiency, with prolonged exposure to high temperatures leading to anthocyanin oxidation and degradation; and excessively high material-to-liquid ratio, requiring excessive solvent immersion in the materials in traditional processes, increasing energy consumption for subsequent concentration. Utility Model Content

[0005] To improve time efficiency and reduce the material-to-liquid ratio, this application provides a high-efficiency extraction and reconstitution device for producing black goji berry beverages.

[0006] The high-efficiency extraction and reconstitution device for producing black goji berry beverage provided in this application adopts the following technical solution:

[0007] A high-efficiency extraction and reconstitution device for producing black goji berry beverages includes a tank, which is vertically arranged and has a sealed structure. A feed pipe and a water inlet pipe are respectively installed at the top of the tank, and a support is installed at the bottom of the tank. A discharge port is located at the center of the bottom of the tank and is connected to a discharge pipe. A vacuum filtration pump is installed on the discharge pipe, and a centrifugal filter is connected to the end of the discharge pipe. A drive motor is fixedly installed at the top of the tank. A shearing and stirring mechanism is vertically arranged inside the tank, with one end of the shearing and stirring mechanism fixedly connected to the output end of the drive motor. A water bath spraying mechanism is arranged around the inner wall of the tank. A water bath heating box is installed on one side of the tank. The water bath spraying mechanism is connected to one end of the water inlet pipe, and the other end of the water inlet pipe is connected to the outlet end of the water bath heating box. A delivery pump is installed on the water inlet pipe.

[0008] By adopting the above technical solution, the tank is designed as a sealed structure to reduce the contact between the black goji berries and oxygen inside the tank, thereby reducing the oxidation and degradation of anthocyanins. The black goji berry raw material and solvent enter the tank through the feed pipe and water inlet pipe respectively in a certain proportion. After soaking and extraction for a period of time, they are extracted by a vacuum filtration pump and transported to a centrifugal filter for filtration. A shearing and stirring mechanism is installed inside the tank. Activating the drive motor causes the shearing and stirring mechanism to rotate, thereby simultaneously stirring and shearing the raw material, accelerating the breakdown of the black goji berry tissue and promoting the release of anthocyanins. A water bath spraying mechanism sprays the raw material inside the tank, ensuring full contact between the black goji berries and the solvent. The water bath heating tank heats the spray water to a suitable temperature, thus enabling hot water extraction without damaging the anthocyanins, extracting all the effective active ingredients from the black goji berries. Subsequent filtration and concentration operations yield the extract, providing a high-quality base solution for subsequent beverage formulation, improving the quality and taste of the beverage.

[0009] Optionally, the shearing and stirring mechanism includes a main shaft, an upper turntable, a lower turntable, shearing blades, and several stirring shafts. The main shaft is vertically arranged, and its upper end is fixedly connected to the output shaft of a drive motor. The upper turntable is fixedly sleeved on the upper end of the main shaft, and the lower turntable is fixedly sleeved on the lower end of the main shaft. Several stirring shafts are evenly arranged around the main shaft. One end of each stirring shaft is fixedly connected to the edge of the upper turntable, and the other end is fixedly connected to the edge of the lower turntable. The shearing blades are fixedly sleeved on the main shaft.

[0010] By adopting the above technical solution, the upper turntable, the lower turntable, and several stirring shafts form a cage space. The main shaft rotates under the action of the drive motor, which in turn drives the upper turntable, the lower turntable, the shearing blades, and several stirring shafts to rotate simultaneously. Due to the setting of several stirring shafts, not only is the stirring force and stirring space increased, but the material can also enter the cage through the gaps between the several stirring shafts. This allows the shearing blades to shear the material during rotation, thereby achieving the purpose of simultaneous large-scale stirring and shearing, thus improving the extraction efficiency and shortening the soaking extraction time.

[0011] Optionally, the water bath spraying mechanism includes a spiral tube, several spray heads, and a switch valve. The spiral tube is arranged around the inner wall of the tank, and one end of the top of the spiral tube is connected to the water inlet pipe. Several spray heads are evenly fixed on the spiral tube, and the switch valve is located on the water inlet pipe.

[0012] By adopting the above technical solution, a spiral tube is arranged around the inner wall of the tank, and several spray heads are evenly distributed on the spiral tube. During operation, several spray heads simultaneously spray the black goji berry raw material from all directions, so that the black goji berry raw material is fully immersed in the solvent. This changes the principle of the traditional process that requires excessive solvent to immerse the material, reduces the material-liquid ratio, and reduces the energy consumption of subsequent concentration.

[0013] Optionally, the bottom of the tank is a conical structure, and a stirring head is fixedly installed below the lower turntable, with the stirring head placed inside the conical structure.

[0014] By adopting the above technical solution, the bottom of the tank is set into a conical structure, which allows all the material to fall into the discharge port and not remain on the sides of the bottom of the tank. The stirring head can be set to stir the material located at the bottom of the tank that cannot be reached by the shearing and stirring mechanism, thereby improving the extraction of the material at the bottom of the tank and preventing the accumulation of material at the bottom of the tank.

[0015] Optionally, a plurality of shearing plates are provided at the bottom of the tank along the generatrix of the conical structure, and all of the shearing plates are fixedly connected to the inner wall of the tank.

[0016] By adopting the above technical solution, a shearing plate is installed at the bottom of the tank, which can not only shear the material at the bottom of the tank during the mixing process, but also prevent the material from accumulating at the bottom of the tank and causing blockage.

[0017] Optionally, the number of shearing plates is three, and the three shearing plates are evenly distributed at the bottom of the tank.

[0018] By adopting the above technical solution, the three shearing plates are evenly distributed at the bottom of the tank, which can disperse the material at the bottom of the tank evenly and further prevent the material from accumulating.

[0019] Optionally, an air inlet pipe is provided on the side wall of the tank, with one end of the air inlet pipe connected to the tank and the other end connected to the air supply device.

[0020] By adopting the above technical solution, an air inlet pipe is set on the side wall of the tank, and N2 or CO2 is introduced into the tank through the air inlet pipe, thereby playing a role in gas protection and reducing the oxidation and degradation of anthocyanins by oxygen in the tank.

[0021] Optionally, a temperature sensor, a pressure sensor, and a pH sensor are also sequentially arranged on the side wall of the tank.

[0022] By adopting the above technical solution and equipping it with various sensors, the temperature, pressure and pH inside the tank can be monitored in real time, thereby enabling precise control of the extraction temperature, time, pH, and whether the tank is sealed, thus improving the extraction efficiency of polysaccharides.

[0023] Optionally, a sealing cap is provided on the top of the tank, and a sealing strip is provided on the sealing cap.

[0024] By adopting the above technical solution, the operator can open the sealed cap at the top of the tank to observe and know the situation inside the tank in a timely manner; and the sealing strip on the sealed cap can reduce the contact between the tank and air during operation and reduce the oxidation of anthocyanins.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By installing a shearing and stirring mechanism inside the tank and starting the drive motor, the shearing and stirring mechanism is rotated, thereby achieving simultaneous stirring and shearing of the raw materials, accelerating the breaking down of black goji berry tissue and promoting the release of anthocyanins. The water bath spraying mechanism can spray the raw materials inside the tank, ensuring full contact between the black goji berries and the solvent. The water bath heating box can heat the spray water to a suitable temperature, thus enabling hot water extraction without destroying anthocyanins, and extracting all the effective active ingredients from the black goji berries.

[0027] 2. By setting up several stirring shafts, not only is the stirring force and stirring space increased, but also the material...

[0028] The material can enter the cage through the gaps between several stirring shafts, thereby enabling the shearing blades to shear the material during rotation. This achieves the purpose of simultaneous stirring and shearing, thus improving extraction efficiency and shortening the soaking and extraction time.

[0029] 3. By circling the inner wall of the tank with a spiral tube and evenly distributing several spray heads on the spiral tube, the black goji berry raw material is sprayed in all directions at the same time, so that the black goji berry raw material is fully immersed in the solvent. This changes the principle of traditional process that requires excessive solvent to immerse the material, reduces the material-liquid ratio, and reduces the energy consumption of subsequent concentration.
