[0025] In this embodiment, when pectins of different molecular weights are produced, their optimal temperatures are also different. The temperature controller can monitor the temperature of the coolant in the water tank 4 in real time, and change the power of the chiller 402 for temperature control, so that the coolant can always regulate the temperature of the solution in the crushing cup 8, and always maintain the optimal temperature for pectin production, thereby ensuring the production quality of the product. The model of the temperature controller is "XMT5-8011K02", and the model of the chiller 402 is "FL-0250". For example, when extracting pectin from apple pomace, the ultrasonic power can be set to 180W, the ultrasonic time to 40 minutes, the material-liquid ratio to 1:25, the extraction temperature to 45°C, and the pH value to 1.5. Under these conditions, the pectin yield is 13.79%. Pectins of different molecular weights can be further separated by ultrafiltration technology, among which pectins with a relative molecular mass greater than 300kDa account for the majority (68.04%), while pectins with a relative molecular mass below 5000Da are less (3.31%).

[0026] Reference Figure 1 and Figure 4In this embodiment, a notch is provided on the top of the water tank 4 as a card slot 802, and a card column 801 is fixedly connected to the bottom of the crushing cup 8. The card column 801 and the card slot 802 cooperate with each other. One side of the water tank 4 is connected to the first pipe 5. The card column 801 and the card slot 802 are provided to facilitate the fixing of the crushing cup 8, and the crushing cup 8 is fixed during processing, thereby improving the stability of the equipment.

[0027] Reference Figure 1 and Figure 3 In this embodiment, the docking component 7 includes a first docking pipe 701 and a second docking pipe 702. Pin grooves 703 are provided on the first docking pipe 701 and the second docking pipe 702. A pin rod 704 is provided between the two pin grooves 703. The first docking pipe 701 and the second docking pipe 702 are respectively installed on the constant temperature pipe 9 and the second pipe 10, and are fixed by the pin rod 704.

[0028] Reference Figure 1 and Figure 2 In this embodiment, the crushing mechanism 6 includes a transducer 601, which is fixedly connected to the output shaft of the motor 3. The bottom end of the transducer 601 is fixedly connected to a polygonal connector 602. Each corner of the polygonal connector 602 is provided with a mounting groove 603. Each mounting groove 603 is connected to a horn 605. A nut 604 is provided on the mounting groove 603. The polygonal connector 602 is shaped as a plurality of rod bodies distributed in an annular equidistant array. Each rod body is provided with a mounting groove 603 and a horn 605 is installed. The ultrasonic generator arranged in the chassis 1 converts electrical energy into mechanical vibration, and converts the mechanical vibration into an ultrasonic signal through the transducer 601, and amplifies the power. Finally, the amplitude is enlarged through the horn 605, so that the ultrasonic energy is more concentratedly transmitted to the material in the crushing cup 8, so that different types of pectin can be applied by replacing different numbers and models of horn 605.

[0029] Working principle: When in use, take out the crushing cup 8, which is filled with extract raw materials and solution, fix it through the slot 802, dock the constant temperature tube 9 and the second pipeline 10 through the docking piece 7, and then start the motor 3 to drive the amplitude rod 605 to rotate for product processing.

[0030] like Figure 2 As shown, the shape of the polygonal connector 602 is formed by splicing a number of rods distributed in a circular equidistant array. Each rod is provided with a mounting groove 603 and a variable amplitude rod 605. When processing pectins of different molecular weights according to different product production requirements, the number or model of the variable amplitude rod 605 can be changed to meet product requirements for processing, thereby improving the practicability of the equipment.

[0031] A chiller 402 and a temperature controller are installed inside the water tank 4. When producing pectins with different molecular weights, their optimal temperatures are also different. The temperature controller can monitor the temperature of the coolant inside the water tank 4 in real time, and change the power of the chiller 402 for temperature control, so that the coolant can always regulate the temperature of the solution in the crushing cup 8, always maintain the optimal temperature for pectin production, and ensure the production quality of the product.

[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
