The main areas of cultivation of sugar beets are in the temperate regions of Europe barilla holding spa and North America, with average temperatures of the heat wave between 16 and 25 C and annual rainfall of 600 mm. In the subtropics, cultivation takes place in the winter months. If rainfall below 500 mm, has to be watered. Beets grow best on deep loamy soils with reaction between neutral and weakly alkaline. As intensive farming barilla holding spa requires adequate barilla holding spa mineral compound fertilization. As for phytosanitary reasons barilla holding spa (p. Eg. Nematodes beet = major cause of fatigue called beet) sugar beets can only be grown every fourth year in the same field, the area of acquisition barilla holding spa of a beet sugar factory is very extensive. The vegetation period is generally 5-6 months. In temperate zones, the crop yields are between 40 and 60 t / ha, while in the subtropics are on average 30-40 t / ha. The sugar content barilla holding spa moves between 16 and 18%. In Spain, for example, almost 99% of the sugar produced is extracted from sugar beet
During harvesting, the beets are cut mode discard the leaves and roots for the extraction process are separated. In the central sugar beets are subjected to a washing with water, so that the earth, stones, leaves and debris or foreign matter are removed.
Subsequently washed sugar beet and is cut into thin slices called a "cossettes". The dimensions are 2 or 3 millimeters wide for best results barilla holding spa in the next stage.
The spread is the removal of the sugar in hot water (at 70 or 80 o C). This stage can be performed leaving barilla holding spa cossettes immersed in water or in continuous mode, counter current. The heated water increases the solubility of sugar, but should not be too hot because it could cause contraction of the surface of the beet pulp, due to protein coagulation preventing the sugar dissolves in water.
After obtaining the juice, which contains many other substances besides sugar. First particles are mechanically separated fiber and plant cells. barilla holding spa Juice chemical purification barilla holding spa occurs by precipitation of a portion of the nonsucrose substances dissolved or dispersed, with subsequent separation of precipitate. In the beet sugar industry has proven effective with calcium carbonate phases, a purification process in which juice is added to the same time lime and carbon dioxide. Synthetic flocculants, in particular polyelectrolytes, improve particle agglomeration barilla holding spa and shorten the settling time in the decanter from the normal 40 to 60 15 to 20 minutes minutes. Another property of the lime is to alkalize the juice, which in reverse order, being acid could promote inversion of sucrose into glucose and fructose. First lime is added gradually to 0.3%, and are precipitated suspended matter (stool). In a second moment lime is added and the precipitate continuous substances (second defecation). Finally CO 2 reacts with lime juice left in forming CaCO 3 is added.
(The quicklime barilla holding spa is CaO (calcium oxide), and is not used in this format because it has excessive reverence barilla holding spa for water, which is found by adding water as it boils and burns the skin. Therefore it is necessary to shutdown . Lime Lime contact with water reacts reaching a temperature barilla holding spa of 90 C so there must protect the container where it is made. should only be done in metal containers or certain plastics During barilla holding spa this process and subsequently the lime becomes caustic and can cause serious chemical burns)
Subsequently proceeds to decant the juice, and then passed to the filtrate (The filtrate is returned to the process, while the filter sludge is discharged) and subsequent concentration in the evaporator station.
Evaporation station several evaporators are in cocurrent in which proceeds to concentrate juice initially at a concentration of 10% to a final concentration of 65% and no greater as it should and
