Description

Differential extrusion thawing promotion and residual blood removal device for ham with bone Technical Field The invention relates to the technical field of meat product processing equipment, in particular to a differentiated extrusion thawing promotion and residual blood removal device for ham with bones. Background In the processing process of the ham with bones, two key procedures of thawing and removing residual blood are usually required. In the traditional process, the thawing mode of standing natural thawing or water bath thawing is adopted, the time consumption is long, the thawing uniformity is difficult to ensure, and a large temperature difference exists between the ham center and the surface layer, so that the internal and external softness degree is inconsistent in the subsequent processing. The residual blood removal is mostly dependent on manual pressing or a simple mechanical rolling mode, and has the problems of high labor intensity, low processing efficiency, unstable removal effect and the like. If the mechanical extrusion mode is adopted to remove the residual blood and promote the thawing, as the bones with the bones are penetrated in the ham with the bones, the bearing capacity difference of the bone region and the pure meat region on the extrusion force is obvious, if the mechanical difference of the bone region and the pure meat region is not distinguished, the force is applied improperly, and the uniform extrusion force is applied, so that the pressure required by the pure meat region for removing the blood and promoting the thawing is met, the broken bone surface layer is extremely easy to break and separate, tiny bone fragments are generated and are dispersed and distributed in the muscle gap, the product quality is influenced, and hidden danger is formed for the edible safety of consumers. If the overall extrusion force is reduced to protect bones, the extrusion force of the pure meat area is insufficient, and the effects of blood discharge and thawing promotion are greatly reduced. In addition, the existing equipment generally lacks on-line detection and grading processing capability for the unfreezing state of the ham, and ham with different unfreezing degrees is mixed into the same processing flow, so that processing parameters are difficult to match with individual differences, and the fluctuation of product quality is large. Disclosure of Invention The invention aims to solve the technical problems that when the uniform extrusion force is adopted for processing, bones are easy to crush and are dispersed in muscles to influence the quality and eating safety of products, meanwhile, the existing extrusion mode is difficult to meet the double requirements of promoting thawing and removing residual blood, and the uniform and consistent processing effect of different batches of ham is difficult to obtain due to different bone distribution differences and different thawing degrees. The invention provides a differential extrusion thawing promoting and residual blood removing device for ham with bones, which is used for extruding ham in a semi-thawing state and comprises a conveying mechanism, a plurality of groups of differential adjustable rolling mechanisms and a driving mechanism, wherein the conveying mechanism is used for carrying and conveying ham, the differential adjustable rolling mechanisms are sequentially arranged above the conveying mechanism along the conveying direction to form a multistage continuous extrusion station, and each group of differential adjustable rolling mechanisms comprises an adaptive reducing roller assembly and a driving mechanism for driving the adaptive reducing roller assembly to rotate and press downwards. The self-adaptive variable-diameter roller assembly comprises a plurality of partition variable-diameter rollers which are axially arranged along the self-adaptive variable-diameter roller assembly, wherein the partition variable-diameter rollers are sequentially divided into a first area corresponding to a pure meat area, a second area corresponding to a bone area and a third area corresponding to the pure meat area, the diameter of the second area is smaller than that of the first area and that of the third area in an initial state, and the diameters of the partition variable-diameter rollers are independently adjustable so as to apply differential extrusion force to different areas according to ham bone distribution. Further, the device also comprises a pretreatment detection section which is arranged in front of the inlet of the extrusion station and comprises a skeleton distribution detection mechanism and a guide mechanism. The skeleton distribution detection mechanism comprises a dual-energy X-ray detection unit and is used for identifying skeleton position, skeleton thickness, bone density and burial depth distribution parameters of the ham, and rolling threshold values and bearing parameters of corresponding sections of the variable d
