The current famous products in domestic market include Jingjiang dried pork slices, Shantou dried pork slices, Hunan dried pork slices, Fujian dried pork slices, Xiamen golden dried pork slices and the like. Although the raw materials and ingredients of the dried meat slice products in various regions are different, the formed flavors and tastes are different, but the processing technology is different. The traditional processing technology of the dried meat slices comprises the following steps: selecting raw materials → bulk meat → trimming → slicing → mixing materials, pickling, seasoning → spreading and sieving → dehydrating and drying → sieving → baking finished product → pressing, slicing → cooling → packaging → finished product. At present, a plurality of procedures in the traditional process of the dried meat slice are manual operations, such as raw meat cutting, trimming, spreading and screening, peeling and screening, slicing, packaging and the like, particularly the spreading and screening process is difficult to replace by machinery and is completed by manual operation, and the thin meat slice with the thickness of 1-2mm is spread on a bamboo screen or a stainless steel screen in a manual mode, which is one of the most important and key steps in the traditional making process of the dried meat slice, and has higher requirements on the technique, skill and proficiency of an operator. Therefore, the manual spreading and screening operation is high in requirement and long in time, continuous processing and industrial large-scale production of the dried meat slices are restricted, and the production efficiency and the benefit of enterprises are seriously influenced.

With the rapid development of the market demand of leisure meat products in recent years, the manual sieving process in the traditional dried meat slice processing gradually becomes a bottleneck for limiting the rapid development of blocks in the dried meat slice industry. Therefore, on the premise of keeping the traditional flavor characteristics and good quality of the dried meat products to the maximum extent, the traditional process is innovated and reformed, the continuous, automatic and industrial production of the dried meat is realized, and the method is a necessary way for obviously improving the production efficiency and economic benefit of dried meat processing enterprises.

and step 3: the rolled and kneaded raw material blocks fall onto a third conveyor belt 31 from the outlet of the vacuum rolling and kneading machine 22, the third conveyor belt 31 conveys the raw material blocks to the lower part of a sorting device 35, a second mechanical arm 33 clamps a mould 38 from a mould cabinet 37 and places the mould on a fourth conveyor belt 32, the fourth conveyor belt 32 conveys the mould 38 to the lower part of the sorting device 35, a camera 352 on the sorting device 35 identifies the raw material blocks, a parallel robot 351 controls a picking mechanism 354 to pick the raw material blocks, the raw material blocks are loaded into the mould 38 in the same muscle fiber direction side by side, the mould 38 is conveyed to the lower part of a pressing device 36 after being filled, a truss robot 361 controls a pressing block 362 to press the raw material blocks in the mould 38, and the third mechanical arm 34 clamps and transfers the mould 38 to a movable shelf 9 after the pressing is completed; the automatic identification of the camera 352 replaces the traditional manual screening, and the same muscle fiber direction is loaded into the die 38 side by side to ensure better stability and consistency of the raw material blocks during the pressing process;

and 4, step 4: after filling the mold 38 with the movable shelf 9, moving the movable shelf into a refrigeration house 4, quickly freezing and forming the raw material blocks at minus 10 ℃, then moving the movable shelf 9 out of the refrigeration house 4, and slightly thawing the raw material blocks at room temperature to form meat blanks for subsequent slicing;

and 5: the movable shelf 9 filled with the formed meat blocks moves to the slicing and flattening area 6, the fourth mechanical arm 63 takes the mold 38 from the movable shelf 9, the formed meat blocks in the mold 38 are poured into the slicer 61, the slicer 61 cuts the meat blocks into meat slices with the thickness of about 2mm, the fifth mechanical arm 64 grabs the empty mold 38 from the movable shelf 9 and places the empty mold 38 at the outlet of the slicer 61, the meat slices produced by the slicer 61 fall into the mold 38, and after the mold 38 is filled with the meat slices, the fifth mechanical arm 64 places the mold 38 filled with the meat slices on the movable shelf 9; the traditional manual spreading and screening is replaced, so that the continuous processing and the industrialized large-scale production of the dried pork slices are realized;

step 6: after the movable shelf 9 is filled with the molds 38 filled with the meat slices, the movable shelf is moved to a drying room 5 for drying and dehydration, the drying temperature is 65-70 ℃, the drying time is 3-5 hours, dry blanks with the water content of 20-25% are formed, and the dried pork slices are primarily molded;

and 7: the movable shelf 9 is moved to the baking area 7, the sixth mechanical arm clamps the mould 38 filled with the dehydrated sliced meat from the movable shelf 9 and puts the mould into the oven 71 for high-temperature baking at the temperature of 200-;

and 8: the die 38 with the baked sliced meat is moved back to the slicing and flattening area 6 by the movable shelf 9, the die 38 is placed on the flattening machine 62 by the fifth mechanical arm 64, and after the sliced meat is flattened by the flattening machine 62, the die 38 is placed back on the movable shelf 9 by the fifth mechanical arm 64;

and step 9: the movable shelf 9 moves to the side of a fourth mechanical arm 63, the fourth mechanical arm 63 grabs the mold 38 filled with the flattened meat slices and pours the meat slices into a slicer 61, the slicer 61 cuts the meat slices into a specified shape and then fills the meat slices into the mold 38, and then a fifth mechanical arm 64 grabs and puts the mold 38 on the movable shelf 9;

step 10: the movable goods shelf 9 is moved to the packaging area 8, and the cut dried pork slice finished products are packaged in the packaging area 8.
