SU95225A1 - The method of obtaining tanning concentrate from ephedra - Google Patents

Description

Concentrated tannic extracts of vegetable origin, used for skin removal, are obtained by extracting with water lipii joBbiUJCiHiOH the temperature of tannic tanning materials.

Ephedra plant ephedra (Ephedra) contains a significant amount of tannids (more than 13% by dry weight). However, this plant is almost never used as a tanning material, since it is difficult to extract tannides from it by churning out extraction.

The proposed method makes it possible to isolate tannids from ephedra in a concentrated form without using the complex equipment of existing tanning extract plants, and also: to organize the production of tannidite in the areas of distribution of thickets of tanny plants for supplies} 1-; p yes tanneries, especially in Central Azni, / honestly tanite-1 mi.

For this reason, you can use the TP-S porridge used in the labyrinth production plant, reducing the inter-roll distance in it and arranging a sieve with a hole diameter b, 75ml1, necessary for separating the powder containing tannks.
