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.

Embodiment 1

[0010] Embodiment 1: Clean the fresh two-layer gray hide of cowhide in a drum with clear water for 1 hour to remove its surface ash. and dust-based powdery substances. Concentration is housed subsequently and be that the drum of 5% ammonium sulfate aqueous solution will continue to clean the above-mentioned skin material that removes surface ash for 2 hours, make the calcium bicarbonate in the powdery material react with ammonium sulfate to generate calcium sulfate and water, obtain thoroughly Ashless fresh splits from which powdery substances have been removed. This step also has the effect of reducing the fat content of the fresh split skin. Then wash with flowing water until the pH value of the fresh split skin is equal to 7. In a drum filled with a 15% hydrogen peroxide aqueous solution, wash the ash-free fresh split skin with a pH value equal to 7 for 1 hour and then let it stand for 8 hours to bleach it, sterilize and disinfect it at the same time, and squeeze it to re...

Embodiment 2

[0013] Embodiment 2: Each wet fresh two-layer cowhide leather material through pre-treatment adopts known methods such as fumigation and dipping to make it taste and color respectively, and the taste and color can be varied. According to the specific dog chew product pattern, choose leather materials with different tastes and colors to cut and combine the epidermis for use. Get its scraps of different tastes and colors and stack them according to the designed basic shape of the skin-pressed dog chew, and then process them into cores with the same method as in Example 1. Cut and combine the edges of each part of the skin that should be connected to overlap and wrap on the surface of the core body, and then the skin-pressed dog chew prototype and the finished product processing method are the same as in Example 1.

[0014] The processing method of the present invention is equally applicable to the fresh split skin of pigskin, and the implementation mode is the same as that of th...

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...
