Description

Technical Field

[0001] The device for cutting the back meat on the poultry breast bone frame of the present invention belongs to the technical field of poultry processing and is applied to the industry of separating the back meat on the poultry breast bone frame. Background Art

[0002] With the rapid and large-scale development of the poultry breeding industry, the domestic demand for poultry meat in the current poultry market is increasing day by day, such as chickens, ducks, and geese. As the market requirements are getting higher and higher, it is necessary to divide the poultry body into more products, and the demand for poultry segmentation is becoming more and more detailed. Only after refined segmentation can poultry meat products enter the common people's market in large quantities. For example, chicken wings, chicken breasts, chicken legs, etc. all need to be divided into separate products to meet the market demand in order to strive for greater comprehensive added value and improve the utilization rate of raw materials.

[0003] At present, although a few foreign companies have fully automatic segmentation production lines, the prices are very expensive; while the domestic slaughter and segmentation lines are basically in a semi-automatic and semi-manual state. In the poultry processing production line, for poultry segmentation, most of the poultry bodies are hung and then segmented. In the existing automatic cutting equipment, mainly the wishbone, large breast, small breast, and chicken legs of the poultry are automatically segmented, while the back meat of the poultry is ignored and still remains on the bone frame. The back meat is located on the back of the breast frame near the chicken neck, with a size of about 4 cm * 6 cm, a thickness of about 1 cm, and a weight of about 15 grams, with chicken skin and part of the neck bone. At present, the back meat is all segmented manually, and the segmented products are greatly affected by the proficiency and mood of the operators. It not only increases the labor intensity of the workers, but also causes the uneven size of the manually segmented products, making the product quality unstable, unable to achieve a unified standard, and reducing the product quality.
