Description

Technical Field

[0001] The utility model belongs to the technical field of casing production, and in particular relates to a drying line for producing collagen casings. Background Art

[0002] Collagen casings are made from collagen fibers from the dermis of cattle and pigs. They are used to prepare protein casings for sausages. They are translucent beige in color and seamless in shape without holes. Edible collagen casings can be used for raw sausages, steamed / smoked products, and dried / steamed products. They are easy to use, have a good taste, and have uniform diameters. Their compressive strength is more than four times that of natural casings, which can extend the shelf life of food to a certain extent. They have advantages that natural casings cannot match.

[0003] In the production process of collagen casings, animal leathers such as pigskin and cowhide need to undergo a series of processes such as defibration and meat mixing. The viscosity and humidity of the finished casings are very high, and preliminary drying is required before subsequent folding and other processes can be carried out. Therefore, casing drying is an extremely important step in the casing production process. In the prior art, air at room temperature such as a boiler is usually used for heating, and the heated air is then used to dry the casings. This heating method has low drying efficiency, uneven heat distribution, and is prone to damage to the casings. Utility Model Content
