Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to a device for cutting beef into strips for preparing beef jerky. Background Art

[0002] Beef jerky is a popular snack food made from beef slices cut into strips. It is prepared in different ways in many cultures, but most of them involve cutting into strips. Its main purpose is to: 1. Ensure that the meat strips can be evenly dehydrated during the drying process to avoid internal deterioration; 2. Ensure that the beef jerky has an ideal taste and texture after seasoning; 3. It is easy to package and eat, and products of the same shape and size are more beautiful. Most of the existing technologies cut beef through a strip cutting device; For example, the patent with patent announcement number CN108782702B and announcement date 2021.05.28 discloses a beef strip cutting device, which records the steps of cutting frozen beef. During cutting, the first cutting knife is moved down to slice the beef. During this process, the push plate is used to squeeze the wedge block to make the second cutting knife move horizontally to cut the beef into strips; but since fresh beef is softer, it is difficult for the second cutting knife to cut the beef slices into strips in the conventional horizontal direction, so it is only suitable for frozen beef; and the position of the second cutting knife and the first cutting knife is fixed. While ensuring the cutting operation of the beef strips, the position of the first cutting knife cannot be adjusted to change the width of the beef slices after cutting. It can be seen that the beef strip cutting device has limitations.

[0003] In view of the shortcomings of the above-mentioned prior art, a beef jerky cutting device is designed to overcome the shortcomings of the prior art and is capable of not only cutting frozen beef but also cutting fresh beef, has strong adaptability, and can adjust the width of the beef slices when cutting, and has a variety of usage methods.
