What are the issues that need to be paid attention to when using a rolling machine for rolling? It is related to the processing technology and raw material types before the rolling machine. For example, for pork of size 2 or 4, it is divided and trimmed into strips of about 5-10 cm, injected and tenderized with salt water, or tenderized and ground before rolling. The time is different. In addition, the salt water (i.e. pickling preparation) you use may also have an impact. Generally, it is better to have a high vacuum degree and control the temperature during rolling. The time is 2-3-4-3, which means rolling for 2 hours and stopping for 3 hours. This is a guiding suggestion. If your machine can lift and lower its head, it is better to design a time for lifting and lowering in the middle, which is conducive to the rolling effect.
