Description

Technical Field

[0001] The utility model relates to a casing dripping liquid recovery and treatment device, belonging to the technical field of waste liquid recovery and treatment. Background Art

[0002] Collagen casings are made of collagen fibers from the dermis of cattle. Auxiliary materials are added and treated with acid, alkali and machinery to form collagen "lumps". They are then extruded, inflated, dried, heated and formed to make artificial casings. During the inflated molding stage, a liquid will be sprinkled to neutralize the collagen casing. The solution is sodium carbonate or sodium bicarbonate. The concentration is ensured by adding liquid during the production process. As the use time of the liquid increases, the solution will become turbid and yellow, which will affect the neutralization effect and the appearance color of the casing.

[0003] The reason why the dripping liquid turns yellow and turbid: During the collagen blowing stage, the dripping liquid is used for neutralization before the casing is completely dry, which will wash away a small amount of broken fibers and auxiliary materials in the casing. These substances will accumulate more and more as the dripping liquid is used for a longer time, causing turbidity and different degrees of color changes. Due to the presence of fine collagen fibers in the solution, filtering is difficult, so the current dripping liquid is directly discharged after a few days of use, resulting in dripping liquid waste and increased production costs.
