Description

one

The invention relates to continuous centrifuges used in various industries.

There is a known method for controlling the process of separating a section of sugar massecuites in inertial centrifuges, which provides for the regulation of the supply of massecuite for separation.

The purpose of the invention is to increase the efficiency of the method. For this, according to the proposed method, the ratio of the number of first and second edemas is determined, the color of the product is measured according to the calibration curve of the relationship between the number of first and second edemas and chromaticity, and the supply of the massecuite for separation of drying is measured depending on the results of the comparison.

FIG. 1 shows a centrifuge; in FIG. 2, the regression curve.

The method is carried out as follows.

The source material is fed into the central zone of the rotor 1, which rotates on the shaft 2. As the material moves along the filtering surface of the rotor, the centrifuge is separated, which enters the fixed receptacles 3, 4 feet and is discharged from the centrifuge through nozzles 5, 6.

If the centrifuging process is disturbed, then a significant portion of the centrate will flow into the second compartment of the centrate receiver. In this case, the ratio of the number of edemas received by receivers per unit of time decreases, and the amount of liquid phase in the treated product increases.

Centrifuge work and product quality at

The outlet is stabilized if the ratio of the first and second edemas is stabilized by a change in the feed of the initial product or the whipping fluid. Example. When centrifuging the massecuite

the second product of sugar production in continuous centrifuges with two taps produces brown sugar and syrup. The quality of the brown sugar depends on the ratio of the amount of molasses per unit of time in the first and second zones. To stabilize the quality of the brown sugar at the centrifuge outlet, the amount of massecuite or whitening liquid supplied to the centrifuge is changed, but not

the ratio of edema is constant.

Controlling a continuous centrifuge with two outlets of a centrifuge to obtain a constant quality brown sugar consists in manually controlling or automatically maintaining a certain ratio.
