摘要:
A heating chamber (28) of a crystallization evaporator (10) for evaporating liquids such as sugarcane liquor, in which the at least one tubular heating element (32) is held by suitable means in a cooking chamber (14), is characterized according to the invention in particular in that a number of tubular heating elements (32) are provided, each formed with a polygonal shape (36) at an extreme end region (34) and connected to one another by means of a weld (38) at this polygonal shape (36) such that they lie one against the other and directly support one another.
摘要:
A process for the production of liquid sugar by forming a sugar solution of water and natural sugar containing juice, adjusting the pH of a sugar solution to the range of from 1.0 to 2.0 to obtain an inverted juice, filtering the inverted juice, decolorizing the inverted juice to obtain sugar syrup, demineralizing the sugar syrup, evaporating the demineralized sugar syrup, and cooling the sugar syrup to form the liquid sugar.
摘要:
Solid saccharides are produced from an aqueous saccharide solution in a process, where the aqueous saccharide solution is admixed with a carrier liquid in which the saccharides are insoluble and that has a boiling point higher than that of water to obtain an aqueous admixture, and where the aqueous admixture is subjected to an evaporation step. The heat for the evaporation is at least partially supplied by a heated surface area to yield a vapor fraction including water and a residue fraction including solid saccharides and carrier liquid.
摘要:
Selon un procédé à plusieurs étapes qui assure une utilisation optimale des substances contenues dans la betterave sucrière, on produit un nouveau sucre brut spécial, du sucre raffiné et les produits secondaires longue conservation, mélasse et pulpes sèches. A cet effet, on extrait premièrement des betteraves sucrières un premier jus pour la production de sucre raffiné, puis un deuxième jus pour la production du nouveau sucre brut spécial et finalement un troisième jus, également pour la production de sucre raffiné.
摘要:
La masse cuite (7) est soumise à un malaxage continu sous vide dans un appareillage (8) permettant d'effectuer ce traitement en au moins deux étapes successives. On sépare ensuite les cristaux de l'eau mère du jet de cristallisation considéré et l'égout pauvre est ensuite recyclé lors des étapes de malaxage sous vide. Le grossissement des cristaux, pour un premier jet de raffiné dépasse 60 %. Application à l'industrie sucrière.
摘要:
The present invention concerns a process for the manufacture of thick juice, as part of a sugar manufacturing process, by evaporative concentration of thin juice of sugar beet, sugar cane, or combinations thereof, using multiple-effect evaporation with n effects, wherein part of the water vapour resulting from evaporation in one or more of the evaporators 1 to n-1, is subjected to thermal vapour recompression using two or more thermal vapour recompressors connected in parallel and wherein the thermally recompressed vapour is supplied to the heat exchange element of evaporator 1 or 2 for heating the thin juice to be concentrated.

Disclosed are methods relating to monitoring the processing of polysaccharides and, in particular, monitoring the processing of guar in order to improve guar yield and/or lower impurity concentration in the wash effluent fluid.
摘要:
The present invention relates to a method for producing refine-grade sugar syrup when harvesting agricultural sugar-containing crops. The present invention relates to the implementation of a new industrial process that comprises the following steps: carrying out a thermal-acid treatment of the sugar-containing liquor; carrying out an electro-chemical and ultra-filtration treatment of said liquor; electrolysing the liquor; processing the liquor in ion-exchange columns with a sorbent; condensing the liquor using a reverse-osmosis method; and evaporating said liquor to a concentration allowing for an extended shelf-life. The liquor is industrially and safely purified using ultra-filtration, reverse osmosis and ion-exchange membranes during the crop transformation process. The sugar-containing product obtained using the method of the present invention may be used in various industries such as in the production of confectionery, alcohol-free beer and tins, for bread baking or in the crystallisation of refined sugar.
