What is the role of vacuum in rolling machine?

Purpose of the air rolling kneader: remove air from the barrel, make it easier for water, seasoning and flavor to enter the food, and distribute flavor and juicy in the whole meat. It does this by shock energy to open the cellular structure of meat and keep the meat in a vacuum. The rolling machine has three functions: vacuum, rolling and discharging.

Vacuum plays a very important role in the rolling kneader. First, vacuum can provide a vacuum environment for the product, which is suitable for long-term curing, to achieve a fresh-keeping effect. When the meat product is in vacuum, the fiber holes are fully opened, which can speed up the rapid entry of the sauce and the curing speed. Finally, the meat product cured in vacuum can improve the freshness of the product without improving its structure, and the taste becomes crisp, Improve the quality of pickled products.

The vacuum roller kneader uses the principle of physical impact to put seasoning accessories, additives and meat into the vacuum roller kneader and vacuumize immediately. The fiber tissue is expanded under vacuum, and moves forward and backward along the inner wall of the drum under the action of the paddle, so that the device has the breathing function. In this process, some pieces of meat were taken to high places by the blades, and then fell freely, rubbing and colliding with the pieces of meat at low places.
