Our Industrial Chiller are used to cool down reheated glue. The hides and other scraps are washed so that dirt is removed, and they are soaked to soften them. This material is called stock, and it is cooked either by boiling it in open tanks or cooking it under pressure in autoclaves. The resulting liquid, called 'glue liquor' is extracted and reheated again to thicken the glue. When cooled, this material looks like jelly and is solid.
