Description

Technical Field

[0001] The invention belongs to the technical field of ham preparation, and in particular relates to a stacking method and a device for preparing light-controlled low-salt ham. Background Art

[0002] Ham is a meat product made from the pig's hind legs through a process called pickling and fermentation.

[0003] Stacking is an important process in the ham production process. It is necessary to stack the hams during the salting and ripening stages. The labor intensity and time consumed account for about 70% of the entire ham production process. During the stacking process, repeated turning operations are required, especially in the salting stage. Stacking and turning the hams are not only to achieve the purpose of shaping the hams, but more importantly, to ensure that the blood in the fresh hams is drained, otherwise, the hams are prone to spoilage.

Not only can the legs not be ventilated during the stacking process, but it is also difficult to let the expelled blood flow away in time, which easily causes the legs to spoil. The only way to reduce the spoilage rate of the legs is to continuously increase the amount of salt used. The labor intensity is high and it is difficult to ensure that the legs do not spoil during the stacking process.
