The top and bottom of the inner wall of the fixing groove (32) are fixedly connected by a fixing rod (33). A movable block (34) is slidably connected to the surface of the fixing rod (33). An iron block (35) is installed on the top and bottom of the movable block (34). Magnets (36) that attract the iron block (35) are installed on the top and bottom of the inner wall of the fixing groove (32). A pulling block (37) is installed on the movable block (34). A limiting block (38) is installed on the bottom of the pulling block (37). A limiting groove (39) that matches the limiting block (38) is provided at the top of the clamping block (31) and at a position corresponding to the limiting block (38).

10. A cold chain-free fresh walnut processing technology, characterized in that: The specific steps include: S1. Choosing walnuts: First, the appearance should be complete. The shell of a high-quality walnut should be complete and smooth without cracks, damage or mold. Second, the weight should be moderate. A high-quality walnut should be moderate in weight. Avoid choosing walnuts that are too light or too heavy. Third, the sound should be crisp. Place the walnut on a hard object and tap it gently. If a crisp sound is heard, it means that the inside is dry and of good quality. Fourth, the smell should be fresh. A high-quality walnut should have a strong walnut aroma. S2, preliminary cleaning and drying: the walnuts selected in S1 are placed in the net shell (7) in the housing (1), and then the net shell (7) drives the walnuts to move into the water in the housing (1), the rotary motor (19) drives the net shell (7) to rotate, the pressing plate (24) seals the top of the net shell (7), and the net shell (7) drives the walnuts to rotate in the water, thereby cleaning. After the cleaning is completed, the servo motor (9) drives the net shell (7) and the walnuts to move to the right side of the partition (2), the heating plate (8) is started, and the walnuts are driven by the net shell (7) to rotate, thereby drying the walnuts; S3, shelling and screening: the walnuts after cleaning and drying are shelled by a shelling machine. During the shelling process, the walnut kernels are screened by a screening machine after shelling to facilitate the screening of walnut shell impurities; S4, seed coat removal: soak the sieved walnut kernels in 5%-8% NaOH solution, and control the temperature at 90-95° C. to remove the seed coat from the surface; S5, fresh-keeping processing: soak the walnut kernels after peeling the seed coat in a VC solution with a concentration of 0.2-0.7% to protect the color, and the soaking time is 1-2 hours; S6, secondary drying process: placing the walnut kernels obtained in S5 into a mesh shell (7), drying them through a heating plate (8), and drying the walnut kernels to a moisture content of 20-25%, wherein the temperature during the drying process does not exceed 40° C.; S7, sterilization and packaging: the walnut kernels dried in S4 are placed in a sterilizer for pasteurization for 2-4 hours. After sterilization, vacuum packaging is performed using a vacuum bag and a vacuum machine.
