Processing method of pressure-moulded dog chewing gum

Abstract

The present invention belongs to an animal food, in particular, it relates to a method for producing pressure-moulded dog chewing gum (a dog food) by utilizing edible hide material. It adopts the wetted fresh second layer of hide material as raw material, and includes three stages of preparing core body, making preform and producing finished product, and every stage respectively has the processes of drying and moulding.

Description

technical field [0001] The invention belongs to animal food, in particular to a processing method of pressed dog chews using edible leather. Background technique [0002] Pressed dog chews in the known technology are only found in bone-shaped or other simple shapes such as pie-shaped dog chews, which are generally called skin-pressed bone or skin-pressed dog chews. The processing method is to wash the fresh two-layer gray skin of cowhide or pigskin to remove the surface ash, and then tie the whole leather around the frame to cool it, so that it is dehydrated, shrunk, wrinkled and dried. The dried leather material is cut to take the whole material as the skin, and the soaked scraps are laid on the soaked skin as the core material. The seams of the skin wrapping the core material must be placed on the side of the pressed product, otherwise it will affect the quality of the finished product. Exterior. After the first molding and preliminary drying, the second molding and thor...

AI Technical Summary

Problems solved by technology

The main defect of the above-mentioned dry leather pressed products is that the plasticity of the skin and scraps after soaking is poor and it is difficult to shape, not only the skin seams on the side of the product are difficult to close, the logo or function of the pressed product surface is concave-convex. The consistency is very poor, and it is also manifested in the fact that the leather materials of the pressed products cannot be tightly bonded, resulting in the expansion and deformation of the leather materials when wet, which obviously aggravates the cracking between the leather materials, and even the crushed products that bite the skin are broken and collapsed.
