TECHNICAL FIELD

[0001] The present application relates to the technical field of preserved meat processing, in particular to a preserved meat quantitative tumbling vacuum dynamic pickling integrated process. BACKGROUND

[0002] In the production process of preserved meat (such as preserved meat, sausage, etc.) and various processed meat products, tumbling pickling is a crucial process, which aims to quickly and uniformly penetrate the seasoning (processing liquid) into the meat block through physical tumbling, so as to achieve the effects of flavoring, texture improvement and shelf life extension. The traditional tumbling pickling equipment is mostly horizontal roller, which is carried out in an intermittent manner under normal pressure. Such equipment and process have many drawbacks: first, the air in the meat block is difficult to discharge under normal pressure, which seriously hinders the penetration efficiency of the processing liquid, resulting in long tumbling time, uneven flavoring, and dark color due to oxidation; second, the single-direction uniform tumbling mode has single and unadjustable extrusion and beating effect on the meat block, which is difficult to simulate the complex mechanical effect of manual kneading, affecting the tenderization of the meat and the fusion of the flavor; third, the traditional equipment has single function, and the processes such as feeding, vacuumizing, tumbling and discharging are separated, which has low automation degree, needs multiple manual intervention, has low production efficiency, and the sanitary conditions are difficult to strictly control. Therefore, there is an urgent need in the art for an automatic and efficient processing equipment and process integrating quantitative feeding, vacuum dynamic tumbling and multi-angle pickling.

At the same time or at a specific stage of the step S3, the spatial posture of the processing container is periodically changed, so that its axis tilts and swings controllably at an angle on both sides of the horizontal reference plane, which promotes the axial reciprocating displacement of the material in the container.

When the rotating shaft 8 rotates, the connecting rod 18 rotates, which drives the sliding ring 14 to slide in the inner concave annular groove 10 through the connecting plate 15. When moving, the connecting rod 18 drives the walking wheel 13 at the end to make wave motion up and down in the track groove 12 of the track frame 11, which drives the connecting plate 15 to move up and down. The sleeve ring 16 slides on the guide rod 17 for guidance. When the connecting rod 18 rotates, it continuously swings up and down to extrude the meat. Under the condition of maintaining vacuum, the material performs revolution motion. At the same time, the material is subjected to a periodically changing radial force in the revolution process, which drives the material to perform reciprocating lifting and extruding motion perpendicular to the revolution direction, forming a composite rolling and kneading combining revolution and radial pulsating extrusion; S4, multi-angle deflection pickling: when pickling, the processing box 1 is rotated to adjust the angle by driving the shaft, which moves the meat inside left and right. At the same time as step S3 or at a specific stage thereof, the spatial posture of the processing container is periodically changed, so that its axis tilts and swings controllably at an angle on both sides of the horizontal reference plane, which promotes the axial reciprocating displacement of the material in the container; S5, discharging: after the rolling and pickling are completed, the discharge outlet 3 is rotated to the lower side, then the discharge outlet 3 is opened, and the rotating shaft 8 is started to continue rotating, which pushes the internal meat out to complete the processing.

[0023] First stage: preparation and loading The control system starts to drive the rotating shaft on the support 9 to rotate, and the entire processing box 1 is turned around its axis until the feeding port 2 is vertically upward. During the turning process, the moving seat 5 fixed at the bottom of the processing box slides in the sliding groove 20 of the base 4, and the rollers at the bottom reduce the friction. When the feeding port 2 reaches the vertical upward position, the cylinder acts to push the support block 7 to extend and accurately insert into the clamping groove 6 at the bottom of the moving seat 5, thereby locking the processing box in the current posture and preventing it from shaking during subsequent operations. The operator or the automatic loading system opens the sealing door of the feeding port 2, and then cuts the meat into a predetermined size and puts it into the processing box. Subsequently, the sealing door is closed and locked.

[0024] Second stage: vacuumizing and injecting conditioning liquid The vacuum pump connected to the processing box 1 is started to extract the air inside the processing box through the negative pressure pipeline to achieve a predetermined vacuum degree. In the vacuum state, a predetermined amount of prepared seasoning conditioning liquid is injected into the processing box through an independent liquid inlet pipeline, which is usually connected to the feeding port or an independent interface. The vacuum environment helps the conditioning liquid spread quickly on the surface of the meat and begin to penetrate inward.

[0025] Third stage: dynamic rolling and kneading and multi-angle marinating Composite rolling starts: the motor driving the rotating shaft 8 is started. The rotating shaft 8 starts to rotate at a constant speed, driving the connecting rod 18 and the meat in the box to move in a circular motion, thereby performing basic rolling.

[0026] Swing motion generation: the end of the connecting rod 18 is fixed with a walking wheel 13, which is constrained in the wave-shaped track slot 12 of the track frame 11 fixed to the box. Therefore, when the connecting rod revolves, the walking wheel is forced to move along the wave track, so that the entire connecting rod 18 generates regular radial lifting motion while revolving. This lifting motion is transmitted through the connecting plate 15 and the elastic sealing belt 19, so that the sliding ring 14 slides in the inner concave ring groove 10 and produces periodic extrusion, lifting and beating effect on the meat, thereby achieving dynamic rolling.

[0027] Angle deflection adjustment: during the rolling process, the control system controls the driving shaft on the support 9 according to the preset program, so that the processing box 1 is unlocked or designed to allow a certain angle to swing, and performs small-amplitude reciprocating deflection, for example, tilting 15-30 degrees to the left and right. This angle change makes the meat in the box flow back and forth in the axial direction on the basis of radial rolling and up-down swinging, further improving the uniformity of marinating. The rolling time, swinging frequency, deflection angle and period can be set according to the product process requirements.

[0028] Fourth stage: discharging After the pickling process is completed, the rotating shaft 8 stops rotating. The control system drives the driving shaft of the support 9 to overturn the processing box 1, so that the discharging port 3 is rotated to the lower side. The cylinder retracts the supporting block 7 to unlock the moving seat. After the processing box is overturned to the position, the sealing door of the discharging port 3 is opened. The rotating shaft 8 is started again to rotate slowly, and the meat material that has completed pickling is discharged from the discharging port by the blades or by the action of gravity, and enters the next process such as stuffing, baking, etc. After the discharging is completed, the equipment is reset to prepare for the next production cycle.
