In the circulation system, the braising soup continues to flow and contacts the meat pieces in real time, realizing braising while heating. This process accelerates heat transfer, allowing the braising soup to fully contact the meat pieces and accelerates penetration and fusion. Moreover, during the flow process, the braising soup and the meat pieces fully exchange heat, accelerating the penetration of the braising soup, ensuring that the meat pieces fully absorb the flavor of the braising soup while heating, thereby improving the braising efficiency and the flavor effect, and greatly shortening the overall braising cycle.

The system has multiple modes including negative pressure tumbling, positive pressure tumbling, normal pressure tumbling and static marinating. It can be flexibly selected according to the characteristics of different materials to achieve personalized marinating and ensure the stability of product flavor and texture. After the braising liquid reaches the set temperature, the steam in the tumbling barrel can also play a role in heat preservation. As a heating medium, steam has good heat conductivity and can evenly transfer heat to the braising liquid and meat in the tumbling barrel, making the temperature distribution in the barrel more uniform. In addition, steam insulation has high thermal efficiency and reduces energy consumption. The installation of automated devices such as automatic lid opening, clamping and locking, rapid pressure relief, angle adjustment mechanism, and rotary drive mechanism improves the intelligence of equipment operation, reduces the workers' participation in the marinating process, reduces the workers' labor intensity, improves production efficiency and operational safety, and improves the stability of the production process and the controllability of product quality.

The inner side of the transmission shaft 1004 is provided with an upper steam flow channel 1706 and a lower steam flow channel 1707, and the steam inlet pipe 1703 and the steam outlet pipe 1704 are symmetrically arranged on both sides of the transmission shaft 1004 and are perpendicular to the transmission shaft 1004. The steam inlet pipe 1703 transfers the upper steam flow to the lower steam flow channel 1707. The steam channel 1706 is connected to the steam insulation chamber, and the steam outlet pipe 1704 connects the lower steam flow channel 1707 with the steam insulation chamber. The guide sleeve 1705 is installed on the end of the drive shaft 1004 away from the tumbling barrel 9. The steam input port and the steam output port of the guide sleeve 1705 are connected to the upper steam flow channel 1706 and the lower steam flow channel 1707 respectively. The guide sleeve 1705 is connected to the steam circulation supply system, so that the steam can evenly wrap the outer wall of the tumbling barrel 9. Combined with the heat insulation effect of the insulation sleeve 1702, the heat loss can be minimized to the greatest extent, ensuring that the temperature of the braising soup in the tumbling barrel 9 is uniform and stably maintained within the set range, providing ideal temperature conditions for the braising process, and helping to improve the braising quality and taste of the product. Compared with the liquid water insulation method, steam is used as the heating medium, which has good heat conduction performance and can evenly transfer heat to the braising soup and meat pieces in the tumbling barrel 9, making the temperature distribution in the barrel more uniform. In addition, steam insulation has high thermal efficiency and reduces energy consumption.

[0029] The present invention also designs a processing technology of a circulating hot brine processing system, which includes the following steps: S1, loading and sealing the barrel: the barrel cover 13 of the braising and kneading machine 1 is opened by the automatic lid opening assembly 14, the product to be braising is loaded into the kneading barrel 9, and the automatic clamping and locking mechanism 15 is activated to lock the barrel cover 13 to ensure the sealing between the barrel cover 13 and the kneading barrel 9 to prevent the braising soup from leaking during the braising process; S2, initial immersion angle adjustment, adjust the tumbling and kneading barrel 9 to a preset 30-degree tilt angle through the angle adjustment mechanism 11, so that the product is completely immersed in the subsequent brine to ensure the initial immersion effect; S3, introducing the brine, starting the brine turnover heating device 2, so that the brine heated in the turnover heating device continuously enters the tumbling barrel 9 through the brine input port; S4, circulating heating, the brine is continuously input until the brine reaches a preset ratio of 2:1 with the product to be braised, then the valve of the second pipeline 5 is opened, and the brine in the tumbling barrel 9 is discharged from the rear brine outlet at an equal flow rate, and is purified through the filtering device 3 through the second pipeline 5. After the brine is free of impurities, it is returned to the turnover heating equipment through the third pipeline 6, thus completing the circulation process; S6, turn on heating and heat preservation, and introduce steam synchronously during the circulating flow heating process. The steam is first input from the guide sleeve 1705, and then passes through the upper steam flow channel 1706 and the steam inlet pipe 1703 in sequence before entering the steam insulation chamber. At the same time, the steam is discharged from the steam insulation chamber and passes through the steam outlet pipe 1704 and the lower steam flow channel 1707 in sequence before entering the guide sleeve 1705 and being output to complete the steam circulation heating. This enables the braising and kneading machine itself to have a heating function, and can cooperate with the external circulating heating method to quickly increase the temperature of the braising soup to the corresponding temperature. The double heating method greatly shortens the time for heating the braising soup to the target temperature.

[0030] S5, suspending the braising soup circulation. After the braising soup reaches the preset temperature, the braising soup circulation process is terminated, and only steam insulation is retained to maintain a constant braising soup temperature. The steam insulation system ensures that the braising soup temperature in the tumbling barrel remains stable during the subsequent braising process through uniform heat conduction, thereby ensuring the quality stability of the product; S7, marinating mode selection, according to the material characteristics, the marinating tumbler 1 selects to perform the corresponding negative pressure tumbling, positive pressure tumbling, normal pressure tumbling, and static marinating any one of the operating modes; S8, material recovery.

[0031] Among them, if the negative pressure rolling and kneading mode is adopted, the negative pressure environment expands the gaps between the food tissues, and the penetration resistance of the braising soup is significantly reduced, which can quickly penetrate into the interior of the food, achieve efficient penetration and uniform flavoring, and improve the taste and flavor of the product. When positive pressure rolling and kneading is adopted, the water temperature can be increased to accelerate heat transfer and collagen hydrolysis reaction rate, so that bone-containing food can be matured faster, greatly improving production efficiency and reducing production cycle. The bones become softer, and the separation of bones and meat becomes easier, which improves the convenience and taste of the product. Normal pressure rolling and kneading can avoid damage to the food caused by pressure changes for processing high-starch food. At the same time, the rotation of the rolling and kneading barrel 9 gently massages and mixes the food, reduces the product breakage rate, and improves the product yield and economic benefits. The use of static braising is further for food with fragile fibers, avoiding the physical damage that may be caused to it by the rolling and kneading process, ensuring the appearance and taste of the product, and meeting the quality requirements of the high-end market. In the static state, the braising soup slowly penetrates into the interior of the food under the action of gravity, achieving a better braising effect, while avoiding the damage to the food structure by the intense braising method.

[0032] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made by technicians in the relevant technical field based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
