Abstract
Description
Technical Field
[0001] This invention relates to the field of milk processing technology, and in particular to a sterilization device for processing high-protein milk. Background Technology
[0002] High-protein milk, due to its high protein content and high nutrient density, is prone to protein aggregation and precipitation during processing, which places higher demands on the uniformity of sterilization. A sterilization device for high-protein milk processing is a special processing equipment designed specifically for the characteristics of high-protein milk, which combines thorough sterilization with protein activity preservation. It effectively kills pathogenic bacteria, spoilage bacteria and spores in milk while minimizing the denaturation rate of heat-sensitive active proteins, thus meeting the dual requirements of nutrient preservation and food safety for high-protein milk products. To address this issue, patent CN214962346U discloses a high-temperature sterilization device for milk processing, comprising a high-temperature sterilization tank body, an inlet pipe connected to the top of the tank body, an outlet pipe connected to the left side of the tank body, a base fixedly connected to the bottom of the tank body, a water tank fixedly connected to the top of the base, a water inlet pipe connected to the front of the water tank, a water pump connected to the right side of the water tank, and a water pump fixedly connected to the bottom of the base. This invention, by incorporating a high-temperature sterilization tank body, inlet pipe, outlet pipe, base, water tank, water inlet pipe, water pump, vertical pipe, cooling jacket, return pipe, cooler, connecting pipe, fixing plate, limiting ring, and sealing cap, solves the problem that existing high-temperature sterilization devices lack cooling capabilities, resulting in milk remaining at a high temperature for an extended period and causing nutrient loss. The high-temperature sterilization device for milk processing mentioned above is not convenient for stirring during use. High-protein milk, due to its high protein content and relatively high viscosity, makes it difficult for heat to quickly penetrate to all areas of the tank in a static or simple flow state.

[0008] With the above structure, when in use, through the structure and the rotational connection mode of the "T" - shaped first rotating block and the "worker" - shaped second rotating block, the connection stability of the stirring component is strengthened and the running晃动 is reduced.
[0009] Preferably, the rotating rod is inclined, the stirring rod is in a "匚" shape, the stirring rods are evenly distributed on the outer side of the bottom of the rotating rod, the bottom end of the support seat is fixedly connected to the middle position of the bottom end inside the sterilization tank, and the rotating sphere and the support seat form a rotational connection through the rotating groove.

[0020] Please see Figures 1-5 The present invention provides a sterilization device for processing high-protein milk, including a sterilization tank 1.
[0021] Reference Figures 1-5 As shown, a triangular bracket 2 is fixed to the bottom of the sterilization tank 1, a feed pipe 3 is fixed to one side of the top of the sterilization tank 1, and a discharge pipe 4 is fixed to one side of the bottom of the sterilization tank 1. An electric heating plate is installed on the inner wall of the sterilization tank 1. Valves are installed on the outer sides of both the feed pipe 3 and the discharge pipe 4. A sealing cover 5 is installed on the top of the sterilization tank 1. A control panel 6 is installed on one side of the sterilization tank 1. A stirring structure 7 is installed on the top of the sterilization tank 1. The stirring structure 7 includes a mounting bracket 701 installed on one side of the top of the sterilization tank 1. A servo motor 702 is fixed to the top of the mounting bracket 701. The output end of sterilizer 2 is fixed with a first rotating shaft 703. A first bevel gear 704 is fixed to one end of the first rotating shaft 703. A second bevel gear 705 is mounted on the bottom side of the first bevel gear 704. A first rotating block 706 is fixed to the bottom end of the second bevel gear 705. Inside sterilizer 1, a second rotating shaft 707 is fixed to the bottom end of the first rotating block 706. A connecting rod 708 is fixed to the outer side of the bottom end of the second rotating shaft 707. A second rotating block 709 is mounted on one side inside the connecting rod 708. A planetary gear 710 is fixed to the top end of the second rotating block 709. A fixing toothed ring 711 is fixed to the bottom end of one side sealing cover 5. A rotating rod 712 is fixed to the bottom end of the second rotating block 709. A stirring rod 713 is fixed to the outer side of the bottom of the rotating rod 712. A rotating ball 714 is fixed to the bottom end of the rotating rod 712. A support seat 715 is fixed to the bottom end inside the sterilization tank 1. A rotating groove 716 is provided inside the support seat 715 on the outer side of the rotating ball 714. The first bevel gear 704 and the second bevel gear 705 are perpendicularly distributed and meshed. The cross-section of the first rotating block 706 is shown below. The second rotating block 709, which is T-shaped, has an I-shaped cross-section. The second rotating block 709 is rotatably connected to one side inside the connecting rod 708. The planetary gear 710 is meshed with the fixed gear ring 711. The rotating rod 712 is inclined. The stirring rod 713 is C-shaped. The stirring rod 713 is evenly distributed on the outer side of the bottom of the rotating rod 712. The bottom end of the support seat 715 is fixedly connected to the middle position of the bottom end inside the sterilization tank 1. The rotating ball 714 and the support seat 715 are rotatably connected through the rotating groove 716.
[0022] After triggering the heating instruction through the control panel 6, the electric heating plate on the inner wall of the sterilization tank 1 starts to work, and the temperature inside the tank is increased through heat conduction. The temperature data is fed back to the control panel 6 in real time. When the preset sterilization temperature is reached, the system automatically switches to the constant temperature mode to maintain a stable temperature to meet the requirement of the sterilization duration. During the heating process, the servo motor 702 is started to drive the first rotating shaft 703 to rotate. The first bevel gear 704 at the end of the first rotating shaft 703 meshes with the vertically distributed second bevel gear 705, transmitting the power to the first rotating block 706 and driving it to rotate around its own axis. When the first rotating block 706 rotates, the second rotating shaft 707 at its bottom drives the second rotating block 709 to revolve synchronously through the connecting rod 708. At the same time, the planetary gear 710 on the second rotating block 709 meshes with the fixed tooth ring 711 fixed to the bottom end of the sealing cover 5, forming a planetary motion, thereby driving the second rotating block 709 to rotate around its own axis. The rotating rod 712 at the bottom end of the second rotating block 709 is arranged in an inclined shape and completes the "revolution + rotation" compound motion along with the second rotating block 709. The "C"-shaped stirring rods 713 evenly distributed on its outer side exert a multi-directional shearing and pushing effect on the milk. At the same time, the rotating sphere 714 at the bottom end of the rotating rod 712 rotates in the rotating groove 716 of the support seat 715, providing stable support for the stirring structure, avoiding shaking during high-speed rotation, and ensuring that the milk at different depths and different regions in the tank can fully contact with the heat, realizing uniform sterilization.
[0023] Refer to Figures 2-6As shown, a cleaning structure 8 is fixed to the other side of the top of the sterilization tank 1. The cleaning structure 8 includes a water tank 801 fixed to the other side of the top of the sterilization tank 1. A water inlet pipe 802 is fixed to one side of the top of the water tank 801. A water pump 803 is installed at the top of the water tank 801. A water pump pipe 804 is fixed to the input end of the water pump 803. A water delivery pipe 805 is fixed to the output end of the water pump 803. An internal cavity 806 is provided inside the first rotating block 706. A sealing groove 807 is provided inside the second bevel gear 705. A dynamic sealing ring 808 is fixed to the bottom end of the water delivery pipe 805 inside the internal cavity 806. A water delivery chamber 809 is provided inside the second rotating shaft 707. A cleaning nozzle 810 is installed at the bottom end of the second rotating shaft 707. A connecting pipe 811 is fixed to one side of the bottom of the water delivery pipe 805. The top of the sterilization tank 1 is... An annular pipe 812 is fixed at one end, and a spray pipe 813 is fixed inside the annular pipe 812. The bottom end of the water pumping pipe 804 extends through the top of the water tank 801 and into the interior of the water tank 801. The water supply pipe 805 and the internal cavity 806 form a dynamic sealing structure through a dynamic sealing ring 808. A sealing ring is installed inside the sealing groove 807. The water supply pipe 805, the internal cavity 806, and the water supply cavity 809 are connected. The interior of the water supply cavity 809 is connected to the interior of the cleaning nozzle 810. Spray holes are evenly arranged on the outer side of the cleaning nozzle 810. The bottom end of the connecting pipe 811 is fixedly connected to the top of the annular pipe 812. The interior of the connecting pipe 811 is connected to the interior of the annular pipe 812. The spray pipes 813 are evenly distributed inside the annular pipe 812 and are arranged in an alternating vertical orientation.
[0024] After sterilization, to prevent the growth of bacteria from high-protein milk residue and affect the quality of the next batch, the water pump 803 is activated. This allows the cleaning solution in the water tank 801 to be drawn through the water pipe 804 and transported through the water pipe 805 to the internal cavity 806 inside the first rotating block 706. The water pipe 805 and the internal cavity 806 form a dynamic sealing structure through the dynamic sealing ring 808, ensuring the sealing of the cleaning solution delivery without affecting the rotation of the first rotating block 706. The sealing ring in the sealing groove 807 further enhances the sealing effect, preventing the cleaning solution from leaking. The cleaning solution in the internal cavity 806 flows into the water delivery chamber 809 of the second rotating shaft 707 and is finally sprayed out through the cleaning nozzle 810 at the bottom of the second rotating shaft 707. The evenly distributed spray holes on the outer side of the cleaning nozzle 810 create a high-pressure water flow that directly washes the stirring components such as the rotating rod 712 and stirring rod 713, removing milk residue adhering to the surface. The rotation of the second rotating shaft 707 drives the cleaning nozzle 810 to rotate 360°, ensuring a more thorough cleaning. Part of the cleaning solution is introduced into the annular pipe 812 through the connecting pipe 811 on one side of the bottom of the water supply pipe 805. The spray pipes 813, evenly spaced and staggered upwards and downwards on the inner side of the annular pipe 812, form a full-area spray surface. The high-pressure water flow covers every area of the inner wall of the sterilization tank 1, achieving thorough cleaning. Cleaning wastewater is discharged outside the tank through the opened discharge pipe 4 valve.
