Vacuum rolling machines play a crucial role in food processing, especially in meat product processing. Its main functions are as follows:

1. Pickling accelerationBy rolling and kneading, the penetration of marinade can be accelerated, allowing meat to absorb seasonings and additives faster, thereby shortening the marinating time.
2. Meat quality improvementThe rolling process can relax muscle fibers, making the meat more tender, smooth, and juicy, and improving the taste and flavor of meat products.
3. Improved water retentionVacuum state helps reduce the loss of moisture in meat products, improve water retention, and make the final product more plump and juicy.
4. Mix evenlyThe rolling machine can also ensure that the marinade and meat are thoroughly mixed evenly, avoiding the problem of local flavors being too strong or too weak.
5. Structural improvementThe vacuum kneading machine uses the principle of physical impact in a vacuum state to make the meat flip up and down, collide with each other, and fall inside the drum, achieving the functions of massage and pickling. At the same time, it adopts the principle of self squeezing with a cylindrical inner guide plate for rolling and kneading. When the cylinder rotates, the meat pieces are squeezed inward according to the guide, and after being knocked and squeezed, the body protein is broken down into water-soluble protein, which is easily absorbed by the human body. In addition, the vacuum kneading machine also has lung breathing function, allowing the product to perform reciprocating movements of expansion and contraction inside the drum, thereby improving the structure of meat tissue.
6. Quality improvementThe vacuum kneading machine is mainly used for deep processing of meat, which can knead, press, and marinate the tender raw meat, and mix it evenly with auxiliary materials, additives, etc. in a vacuum state. In a vacuum state, meat will exhibit an expanded state, which can allow the proteins in the already tender raw meat to fully contact with salt water, accelerate the dissolution and interaction of proteins, increase the adhesion between meat pieces, and make the meat pieces color, improve the tenderness and water retention of the meat, and improve the quality of the meat pieces.

In summary, vacuum rolling machines have multiple functions such as accelerated pickling, improved meat quality, enhanced water retention, uniform mixing, improved structure, and improved quality. These functions make them widely applicable in meat processing.
