a new method of tanning hides the head vegetable water crop and / or locust bean gum pomace and natural tannin rich.

摘要

this invention relates to the use of concentrated vegetable water from the natural evaporation from the elements in the greenhouse using solar energy. (1) the thus obtained is rich in tannin concentration of the natural order of 14% of poly phenols.mixing it up with the pomace is used instead of the chromium salts compounds that are toxic and harmful to health and the environment for the tanning of hides and skins. by the same technique, we used industry wastes that come from the carob pulp maceration of the locust bean gum to extract sugar from locust bean gum (2).these wastes have a tannin content of about 18%. the results showed that the quality of the best tanning process without heavy metals and environmental carcinogens.the invention has a double benefit: (1) replace chromium salts harmful by tannins and plant waste of vegetable water locust bean gum; (2) a non biodegradable industrial emissions containing poly phenols to tan hides.
