(54) CARDBOARD FOR WINE FILTRATION

I

The invention relates to the pulp industry (paper industry, in particular the production of filter material and can be used in the food industry to filter wines, tinctures, beers, soft drinks, etc.

A known cardboard 1 for filtering wines, liqueurs, tinctures, which contains,%: asbestos 15, diatomite 15, unmercerized cellulose 10, mercerized cellulose 6 O,

However, this cardboard has a low filtration rate, which leads to frequent filter recharges, high filter consumption and loss of product to be cleaned. In addition, it is known that iron oxide strongly influences the durability of wine materials, beer and beverages, turbidity prematurely occurs, therefore, the use of diatomite, which contains more than 2% iron oxide, strongly affects the quality of filtered liquids. Diatomite is also a naturally occurring finely dispersed material, and therefore, it can enter the filtrate during the filtration process.

Also known cardboard 2 JWH filtering liquor-liqueur products, which contains; %: mercerized cellulose .57-60, unmercerized cellulose 2025, chrysotile asbestos 14-18. Such cardboard has a low filtration rate, which leads to frequent filter recharges, high filter consumption and losses of the filtered solution, and the required purity is achieved after passing the solution through these plates twice.

Closest to the proposed invention is a filtering board for filtering wines containing,%: mercerized cellulose 25, unmerisable tsegaoloza 68, chrysotile asbestos 7.

The disadvantages of this paperboard are the low filtration rate - O, 7 mm.

The content of Lapland diatomite in cardboard (except for grade 1J negatively affects the durability of wine materials, so

contains 2.0% iron oxide, which affects color and premature clouding. Diatomite is a natural porous-bent material mixed with clay (the latter gives a taste to drinks), and during filtration it is removed and gets into the filtrate, frequent re-loading of the filter press leads to a large consumption of cardboard and significant losses of filtered products.

The aim of the invention is to increase the filtration strength of cardboard.

The goal is achieved by the fact that the cardboard additionally contains comminuted expanded perlite with a particle content of not more than 5 µm in an amount of 65-75%, 1 si of the following ratio of components, May,%. J Mercerized cellulose 22,7-24,4 Unmerised,

The resulting filter - cardboard has the following characteristics: filtration rate is 23.4 hours, optical density (determined on an FEK-56 device filtered through the resulting filter - cardboard coincides with optical density through a filter - cardboard, in production conditions of the wine industry, and is equal to 0, OO9%.

Example 2. Merserized cellulose, unmercerized cellulose, chrysolite asbestos, crushed expanded perlite (with a fraction less than 50 microns of 65-75%) are mixed in an aqueous medium (with further filtration, pressing and drying) in the following amounts,%.

The resulting filter - cardboard has the following characteristics: the filtration rate is 26.8 to m-hour, the optical density (determined on the FEK-56 device) filtered through the resulting filter - cardboard matches the optical density through the filter - cardboard, produced in conditions of the wine industry, and is equal to 0,009%.

The use of the proposed cardboard filter makes it possible to increase the filtration rate and the quality of the filtrate, reduce the consumption of the cardboard components per unit of production, use a cheaper material - perlite of volcanic origin.
