A Certain Animal Skin Deep-processing Food Enterprise

1. Hides are conveyed into the horizontal drum washing machine via a conveyor belt, where they are thoroughly soaked in water to soften and undergo timed rotation and stirring (during which hot water is introduced and the water is continuously filtered and replaced for cleaning). This removes impurities and contaminants from the hides. The washing water is recycled through the hair filter to meet specified requirements before being discharged in reverse;
2. After preliminary cleaning, the hides are reversed and transferred to a high-pressure steam chamber. Internal high-pressure steam melts the hides into liquid, which is then discharged, filtered to remove hair, and transferred to storage tanks and vacuum concentrators;
3. In the vacuum concentrator, using the principle of high vacuum and low boiling point, excess moisture is efficiently evaporated before being transferred to the jacketed kettle;
4. The jacketed kettle undergoes prolonged boiling at a specific temperature to produce a highly concentrated collagen protein solution.
