Description

Pet chew and preparation method thereof
Technical Field
The application relates to the technical field of pet foods, in particular to a pet chew and a preparation method thereof.
Background
The pet chew is a functional pet chew food, the pet chew is generally manufactured into a bone and strip-shaped shape, is a snack specially designed and developed for pet dogs, is suitable for dogs to play and gnaw and bite due to the characteristics of the dogs in the shape, has the requirements of chewing and gnawing in the growth process, can maintain the health of the oral cavity through chewing, avoids the formation of dental plaque and dental calculus, and can be dried before being packaged so as to avoid excessive moisture and damage to the dog chew.
The existing technology for baking the biting gum mostly hangs the long biting gum on a baking frame, then sends the long biting gum into a baking room for baking, and cuts the long biting gum into biting gum blocks with the length of about fingers according to the requirements of users after the baking is finished. However, because the biting gum contains a certain amount of water before drying, in the suspended drying state, the long biting gum is easily accumulated downwards under the action of gravity to deform when being suspended, so that the final biting gum finished product is thin and thick, the product size is different, and the uniformity of the product is influenced.
