Description

The utility model relates to equipment for the production of pectin from sugar beet and beet pulp.

There is a known pectin production line containing a raw material feeder, a rotary cavitation extractor, an intermediate collector, a washing machine, a heat exchanger, an ultrafiltration unit, a packaging unit and a sterilizer, and also a means for supplying water and acid to a rotary cavitation extractor (Golubev V.N. , Shelukhina N.P., Pectin: chemistry, technology, application.- M .: IEChATN RF, 1995, p. 310-311).

The disadvantages of this line are low productivity and low yield of pectin.

The closest technical solution to the proposed one is a sugar beet pectin production line (patent RU (11) 70248 U1, (22) 05/30/2007) containing a series-connected raw material feeder, beet grinder, diffusion apparatus, pectin extractor, pectin coagulator, filter, dryer , a cooler, a packaging apparatus, and also a water supply means connected to a diffusion apparatus, a hydrolyzing agent supply means connected to a pectin extractor, and an alcohol supply means connected to a filter.

The disadvantages of this line are the lack of a stage of purification of the beet pulp from dyes that reduce the quality of pectin, loss of gel-forming properties of pectin at the stage of electrocoagulation.

The technical essence of the claimed utility model consists in the fact that in a pectin production line containing a raw material feeder, a beet shredder, a diffusion apparatus, a pectin extractor, a dryer, a cooler, a packaging apparatus, and a water supply means connected to a diffusion apparatus, a supply means hydrolyzing agent connected to a pectin extractor after a diffusion apparatus, an apparatus for clarifying and washing pulp is added, as well as a clarifier regeneration apparatus, after extracting A pectin is added in series with a centrifuge to remove pulp particles, instead of a membrane unit, a pectin coagulator, in which pectin is electrocoagulated, and an electrodialyzer is used to remove salts and ions of a hydrolyzing agent, a microfiltration unit to remove suspended solids, an ultrafiltration module to remove ballast substances and concentrating the extract, precipitant, centrifuge for separating coagulate, vacuum evaporation

apparatus for extracting alcohol from the coagulate, a distillation column for alcohol regeneration, as well as clarifier supply means connected to the pulp clarification and washing apparatus, clarifier regeneration apparatus connected to clarifier supply means, alcohol supply means connected to precipitant.

The proposed production line provides for the purification of pulp from dyes, the exclusion from the production line of the electrocoagulation stage, which impairs the gel-forming properties of pectin, the inclusion of electrodialysis, microfiltration units and ultrafiltration module in the line, allowing to obtain high-quality pectin.

The drawing shows a diagram of the proposed line.

The line contains a raw material feeder 1 connected in series, a beet shredder 2, a diffusion apparatus 3, a pulp clarifier and rinse apparatus 4, pectin extractor 5, a centrifuge for removing pulp particles 6, an electrodialyzer 7, a microfiltration unit 8, an ultrafiltration module 9, a precipitator 10, a centrifuge for separating coagulate 11, a vacuum evaporator 12, a drying unit 13, a cooler 14, a packaging apparatus 15, and also a water supply means 16 connected to a diffusion apparatus 3, a clarifier supply means 17, connected with a device for clarifying and washing pulp 4, means for supplying a hydrolyzing agent 18, connected to a pectin extractor 5, a clarifier regeneration apparatus 19, connected to a means for supplying a clarifier 17, alcohol supply means 20, connected to a precipitant 10, a distillation column 21 connected to means of supplying alcohol 20.

In the proposed line, sugar beets from beet washers of a sugar factory are used as raw materials.

The washed beets from the raw material feeder 1 are fed to the root crop chopper 2, in which the beets are crushed to particles ranging in size from 3 × 3 to 6 × 6 mm, which accelerates the diffusion process from beet chips. The crushed beets enter the diffusion apparatus 3 (patent No. 2324741), in which the extraction of sugar beet juice by diffusion (diffusion juice) takes place. To this end, water is sent to the diffusion apparatus by the water supply means (16) to extract sugar from beet chips. Diffusion is carried out by the countercurrent motion of the solid (beet) and liquid phases (softened water) and is accelerated by pulsation oscillations superimposed on the liquid phase. The diffusion process takes place in very mild conditions (temperature 30-40 ° C for 30 minutes). The extracted diffusion juice goes for further processing into sugar production.

Beet pulp is fed by a conveyor to the apparatus for clarification and washing of pulp (4) in order to remove coloring substances. The clarified beet pulp is subjected to repeated washing from the clarifier.

Sugar-free, clarified and washed beet chips enter the pectin extractor (5), where the prepared hydrolysing agent is fed by means of the hydrolyzing agent (18).

The resulting extract is purified by centrifuge to remove pulp particles (6).

To remove metal cations, anions of acids and salts, which worsen the gel-forming properties of pectin, the extract is processed on an electrodialyzer (7). Electrodialysis treatment leads to an increase in the purity of pectin and an improvement in the basic quality characteristics on which the properties of pectin depend.

For finer purification of the pectin extract, removal of fine suspensions, colloidal particles, microorganisms with a size of 0.1-1.0 microns, microfiltration is carried out.

From the microfiltration unit (8), the extract is sent for ultrafiltration to the ultrafiltration module (9).

Ultrafiltration processing of pectin extract is carried out in order to remove low molecular weight pectins, monosaccharides, as well as thickening the pectin extract before drying.

The purified extract from the ultrafiltration module is sent for precipitation into the precipitant (10), where ethanol is supplied with the alcohol supply means (20) for precipitation.

The precipitated extract is aged for one hour to form a pectin clot. Pectin coagulate is decanted in a centrifuge to separate the coagulate (11) and fed to a vacuum evaporator (12) to extract alcohol from the coagulate. From the vacuum evaporator, pectin coagulate is fed to the drying unit (13). A fine product with a moisture content of 8% comes out of the drying unit, which is then to be cooled in a cooler (14) and packaged in a packaging apparatus (15).

The spent clarifier undergoes regeneration in the clarifier regeneration apparatus (19), then it is supplied to the clarifier supply means (17).

The spent alcohol after decantation of the pectin coagulate from the centrifuge and the vacuum evaporator is sent to the distillation column (21) for regeneration, after which it returns to the technological process.

The technical result, which consists in improving the consumer properties of the obtained product, is achieved by preliminary clarification of the raw materials, effective extraction to obtain an extract with a high relative pectin content, a sequential processing system of the extract, consisting of mechanical, electrochemical and membrane treatment.

The resulting clarified extract contains a high proportion of the target component with a standardized composition.
