CS229775B1 - Method of purifying of juice by lime milk or carbonation - Google Patents

Description

The invention relates to a method of purifying lime juice with milk and saturation.

The prior art methods of purifying diffuse fame with lime milk and saturation have divided the total amount of lime milk to be cleaned at a ratio of at most 1 s <4; 5> s ^ 0; 0.95 ^ · This slurry does not produce enough sludge in the last saturation, which slows down the decomposition reactions of calcium complexes, increases calcification and deteriorates the color of the glory. Lack of sludge does not allow pre-rinsing and fining mixtures means·

The above drawbacks are overcome by the lime milk purification process and the saturation of the present invention, which consists in dividing the total amount of lime milk to be cleaned into three basic proportions in a ratio of 1: 0.6 (s). wherein the first base is mixed with the sludge from the final saturation and the pre-blend of the mixture is pre-clarified, then the pre-clarified glory is treated with a second base of lime milk at a temperature of 20 ° C. 80 ° C and so lime Glory is subjected to saturation, or the second base is added simultaneously, or a combination of both, the saturated lime is subjected to separation, the pure fraction is mixed with the clarification mixture formed by the final saturation sludge and the third base lime milk. the lime juice thus heated is heated to a temperature of 90 ° C to 105 ° C and subjected to saturation or simultaneous saturation, the turbid juice is subjected to separation and the separated sludge is used to prepare the pre-clarification and clarification mixtures.

The method of purifying the leachate with lime milk and saturation according to the invention achieves up to 20 times lesser coloration of the lungs,

229 775 Rises from epurational affection by 2 ft 5 X and sludge from last saturation can be used as an initial filter medium, such as heavy glory or clergy filtration ·

For example, the process of purifying long-lime filament yarn with saturation according to the invention may be operated as follows: the total lime batch is divided into three basic portions at a dip of 1: 2 with 5, resulting in a 0.275 X CaO addition. on pre-treatment, 0.55 on first saturation and 1.375 X CaO n · r · on ripple not second saturation · Ex1 total dose of 2.2 X CaO n.r The glory was out. The precluded glory is treated with a second basic fraction, i.e. 0.55 X CaO n at 60 [deg.] C. and the lime so lime is subjected to saturation. The saturated aa is subjected to separation, the net fraction a, and the fining snow formed by the quenching of the second saturation of e thirds of the basic lime fraction, i.e., 1.375 X CaO n.r. The limed fame was heated to 98 ° C and subjected to sarurael. From the muddy Glory, the edaeparated sludge is used to prepare the pre-cuts and clarifying angel.
