Description

Technical Field

[0001] This utility model relates to the field of sterilization technology, and more specifically, to a sterilization pot for quick-frozen corn production and processing. Background Technology

[0002] Firstly, regarding sterilization methods, traditional autoclaves mostly employ agitation-based sterilization, a design with significant limitations. While agitation-based sterilization allows for even heating of the material within the autoclave, the stirring process can easily cause damage to the corn, affecting the quality of the final product. In contrast, rolling and tumbling is gentler, effectively preventing material damage while ensuring even heating of the corn within the drum, thus improving sterilization efficiency.

[0003] Secondly, the inconvenience of installing and disassembling high-temperature components is also a significant problem. Traditional high-temperature components are usually fixed to the main body of the sterilizer, and the disassembly and installation process is complex and requires a lot of time and manpower. This not only increases maintenance costs but also affects production efficiency. However, the new quick-freezing corn sterilizer achieves rapid connection and separation of high-temperature components through the design of heating and unloading mechanisms and auxiliary loading and unloading mechanisms. The cooperative structure of the clamping pipe and clamping rod, combined with the linkage control of the outer rotating sleeve and spiral plate, makes the installation and disassembly of high-temperature components simple and quick, greatly improving the convenience of operation and production efficiency.

[0016] Compared with the prior art, this utility model provides a sterilization pot for quick-frozen corn production and processing, which has the following beneficial effects:

[0017] This utility model is equipped with a heating sterilization mechanism. The drum is mounted on the support base of the main frame via a rotating shaft and can rotate freely to ensure that the corn is heated evenly inside the drum, thereby improving the sterilization effect. The drive motor drives the rotating shaft to rotate through the transmission belt assembly, so that the drum rotates continuously, which simplifies the transmission structure and reduces maintenance costs.

[0034] More specifically, open the flip cover 23 on the side of the drum 3, and use the push-pull handle 24 to load the corn to be sterilized into the drum 3. Then close the flip cover 23, insert the locking rod 7 into the locking tube 6, rotate the outer rotating sleeve 13, the spiral plate 14 slides along the spiral groove 15, pushing the longitudinal pressure ring 12 down, causing the embedded ball 11 to engage with the embedded groove 8, locking the high-temperature component 1, and starting the drive motor 20. The drive belt assembly 21 drives the rotating shaft 4 to rotate, and the drum 3 rotates accordingly. The heat generated by the high-temperature component 1 acts evenly on the rotating drum 3, ensuring that the corn inside is heated evenly, achieving a thorough sterilization effect. After sterilization, rotate the outer rotating sleeve 13 in the opposite direction, the spiral plate 14 slides along the spiral groove 15, pushing the longitudinal pressure ring 12 upward, the embedded ball 11 disengages from the embedded groove 8, and the locking rod 7 is unlocked. Remove the high-temperature component 1, open the flip cover 23, and use the push-pull handle 24 to remove the sterilized corn.

[0035] In summary, during the use or operation of the overall equipment: when the heating sterilization mechanism is in operation, the mechanism mainly consists of a drum 3 and a rotating shaft 4. The drum 3 is mounted on the support base 5 of the main frame 2 via the rotating shafts 4 at both ends, allowing it to rotate freely. The high-temperature component 1 is fixedly mounted on the main frame 2, maintaining an appropriate distance from the side of the drum 3. During operation, the drive motor 20 drives the rotating shaft 4 to rotate via the transmission belt assembly 21, thereby causing the drum 3 to rotate continuously. The side of the drum 3 is equipped with an openable flip cover 23 for easy loading and unloading of materials. During the sterilization process, the heat generated by the high-temperature component 1 is evenly applied to the rotating drum 3, ensuring that the corn inside is heated evenly, achieving a thorough sterilization effect.

[0036] When the heating loading and unloading mechanism is in operation, the mechanism adopts a cooperative structure of clamping tube 6 and clamping rod 7 to achieve quick connection. The clamping rod 7 is fixed on the mounting plate 25 of the high temperature component 1 and can be accurately inserted into the clamping tube 6 fixed on the main frame 2. The side wall of the clamping rod 7 has an embedding groove 8. The clamping tube 6 is provided with a rotating plate 10 with an embedding ball 11. When the clamping rod 7 is inserted into place, the longitudinal pressure ring 12 presses down on the rotating plate 10, forcing the embedding ball 11 to be inserted into the embedding groove 8, forming a stable connection.

[0037] When the auxiliary mechanism needs to be loaded and unloaded, the movement of the longitudinal pressure ring 12 is controlled by the linkage of the outer rotating sleeve 13 and the spiral plate 14. The outer rotating sleeve 13 is limited to rotate and is installed on the outer wall of the clamping pipe 6. The spiral plate 14 is installed at the bottom end of the outer rotating sleeve 13. The side wall of the longitudinal pressure ring 12 is provided with a spiral groove 15. The spiral plate 14 and the spiral groove 15 are slidably connected. When the outer rotating sleeve 13 is rotated, the spiral plate 14 slides along the spiral groove 15, pushing the longitudinal pressure ring 12 to move up and down. Multiple sets of shrink blocks 16 are slidably installed at the top end of the outer rotating sleeve 13. A tightening spring 17 is provided between adjacent shrink blocks 16. Multiple sets of fixing blocks 18 are fixedly installed at the top end of the outer wall of the clamping pipe 6. The shrink blocks 16 squeeze different fixing blocks 18 in sequence, so that the outer rotating sleeve 13 stably drives the spiral plate 14 to rotate, forming a ratchet-type positioning to ensure the stability and accuracy of the operation.

[0038] Open the flip cover 23 on the side of the drum 3, and use the push-pull handle 24 to load the corn to be sterilized into the drum 3. Then close the flip cover 23, insert the locking rod 7 into the locking tube 6, rotate the outer rotating sleeve 13, the spiral plate 14 slides along the spiral groove 15, pushing the longitudinal pressure ring 12 down, causing the embedded ball 11 to engage with the embedded groove 8, locking the high-temperature component 1, and starting the drive motor 20. The drive belt assembly 21 drives the rotating shaft 4 to rotate, and the drum 3 rotates accordingly. The heat generated by the high-temperature component 1 acts evenly on the rotating drum 3, so that the corn inside is heated evenly, achieving a thorough sterilization effect. After sterilization, rotate the outer rotating sleeve 13 in the opposite direction, the spiral plate 14 slides along the spiral groove 15, pushing the longitudinal pressure ring 12 upward, the embedded ball 11 disengages from the embedded groove 8, and the locking rod 7 is unlocked. Remove the high-temperature component 1, open the flip cover 23, and use the push-pull handle 24 to remove the sterilized corn.
