Description

Technical Field

[0001] The invention relates to a method for curing collagen casing. Background Art

[0002] Collagen casings are made from livestock skins, tendons, etc., so they are edible. Although the price of collagen casings is about 10-15% higher than that of natural casings, their productivity is about 20-30% higher than that of natural casings, so it is more cost-effective to use collagen casings. Its characteristics are that it does not require cleaning and selection, and is suitable for mechanical filling, and the product size is uniform.

[0003] The existing method for curing collagen casings usually uses pig skin, animal tendons and auxiliary materials to make collagen balls, which are then extruded into tubular films through an extruder, and the tubular films are dried and cured to obtain edible collagen casings.

[0004] The product performance of collagen casings is closely related to their wall thickness, so the wall thickness of the collagen casings needs to be controlled; however, current methods for curing collagen casings do not provide feedback control over the wall thickness of the collagen casings and cannot adjust the wall thickness of the collagen casings in real time, so there is room for improvement. Summary of the invention

[0005] In order to solve the defects of the prior art, the present invention provides a method for curing collagen casings, which comprises the following steps: using pig skin, animal tendons and auxiliary materials to make collagen balls, and then using an extruder to extrude the collagen balls into tubular films, and drying and curing the tubular films to obtain collagen casings; arranging an extrusion block and a molding ring at the output end of the extruder so that the collagen balls are extruded into tubular films through the gap between the extrusion block and the molding ring; and detecting the wall thickness of the collagen casing after drying and curing in real time, and controlling the position of the molding ring according to the change of the wall thickness of the collagen casing; when the wall thickness of the collagen casing becomes thicker, driving the molding ring close to the extrusion block; and when the wall thickness of the collagen casing becomes thinner, driving the molding ring away from the extrusion block.

[0006] The specific contents of the present invention refer to the specific implementation modes.

[0007] The advantages and beneficial effects of the present invention are: providing a collagen casing solidification method, which can feedback control the wall thickness of the collagen casing, and then can adjust the wall thickness of the collagen casing in real time, and finally can improve the product performance of the collagen casing.

[0008] The present invention detects the wall thickness of the collagen casing after drying and curing in real time, and controls the position of the forming ring according to the change of the wall thickness of the collagen casing; When the wall thickness of the collagen casing becomes thicker, the telescopic cylinder drives the sliding support frame to move leftward, and the sliding support frame drives the casing and the forming ring to move leftward, so that the forming ring is close to the extrusion block; in this way, the wall thickness of the collagen casing will no longer become thicker; When the wall thickness of the collagen casing becomes thinner, the telescopic cylinder drives the sliding support frame to move rightward, and the sliding support frame drives the casing and the forming ring to move rightward, so that the forming ring is away from the extrusion block; in this way, the wall thickness of the collagen casing will no longer become thinner; Therefore, the present invention can perform feedback control on the wall thickness of the collagen casing, and further can adjust the wall thickness of the collagen casing in real time.

[0009] The screw of the present invention is arranged on the end plate, and the end plate is slidably matched with the inner wall of the casing. The end plate is also fixedly connected to the column through a connecting rod, so that the normal operation of the screw is not affected when the casing is translated left and right; that is, the present invention adjusts the relative position of the forming ring and the extrusion block under the premise of ensuring the normal operation of the screw.
