Description

{CURING APPARATUS FOR MEAT}

TECHNICAL FIELD The present invention relates to a meat-dewatering apparatus, and more particularly, to a meat-dewatering apparatus including a meat-dewatering apparatus that performs a dewatering process by filling a dewatering solution.

In the production of the processed meat, the papermaking process is carried out. Meats include beef, pork, chicken, and lamb. In particular, chicken meat is different from other meat, so it is strong, so it is processed in a salt water process to make it soft and elastic.

In the poultry processing, various kinds of spices, herbs and vegetables are used to produce a poultice liquid in order to catch the odor of the chicken, and the salt is included in order to make the chicken poultry. Through this purging process, the taste and flavor of the meat can be improved.

The purging process can be carried out using injection, tumbler, immersion, massage, and other methods. The tumbler method is a method of pouring chicken into a vacuum device, so that it is easy to use because of short dipping time. On the other hand, there is a case in which chicken tangles to each other during tanning, or tearable by sharp bones cutting.

In the conventional method, the meat is immersed in the saline solution and aged. The massage method is a method in which the saline solution penetrates into the meat by the hand.

The double tumbler method is a method in which meat is put into a vacuum or non-vacuum device and then mixed mechanically. This method is suitable for the treatment of large volume meat, but as described above, May be deteriorated.
