Definitions
- the invention relates to a process for the recovery of disaccharides from disaccharides containing tuberous plants according to which a solution of disaccharides in water is first subjected to ultrafiltration and subsequently to deionization.
- the so-obtained sterile thin juice can be completely freed of all salts by means of cation- and anion exchangers so that a solution is obtained which completely corresponds with the refined juice.
- a sugar is recovered which does not contain molasses as a by-product which generally contains at least 1/6 of the sugar from the beets and is inferior in comparison with sugar.
- colloidal products which have been removed separately contain proteins, glutamic acid, threonine, proline and phenyl alanine which are more valuable than molasses.
- the water used for the extraction should be as pure as possible.
- the water should not contain soluble substances which affect the purification of the juice.
- Especially water containing alkaline metal salts is disadvantageous because such salts inhibit the crystallization of large amounts of sugar and increase thereby the not contemplated molasses yield.
- the crude juice is heated at 85°C and mixed with an excess of slaked lime.
- the present free acids form therewith insoluble salts which with many other contaminations for instance proteins flocculate.
- a part of the lime forms calcium monosaccharate and another part dissolves.
- the slimy precipitate cannot be filtrated. For that reason carbon dioxide gas and steam are introduced so that the saccha- rate is decomposed and forms with the dissolved lime insoluble calcium carbonate which can be filtrated.
- the sugar present therein does not need to be extracted by diffusion as necessary with cuttings but sugar present in dissolved form in the cells of the tuberous plants can be rinsed out by simply washing with water of less than 60°C of the cells crushed by the mechanical treatment.
- the mechanical production of a mush may for instance be carried out by grating with a in the potato industry usual grating apparatus, a centrifugal pump with open blower or an oscillating mill, however, preferably with the mentioned grating apparatus.
- the permeate contains more sodium and potassium salts than thin juice which is obtained according to the classic method because a considerable part of the potassium- and sodium salts which end up in the molasses according to the classic process now comes in the permeate according to the process according to the invention.
- the permeate should be led over an ion exchanger.
- the reduced mass is first separated for the most part from the liquid present therein and then subjected to an extraction with water of at most 10°C.
- the contact time at the extraction is at least hour but such contact time is seldom necessary because in fact the extraction is momentary at the first contact with water.
- the amount of water used for the extraction is chosen in such a way that the obtained sugar solution has a sugar content of 12-14% by weight.
- a further important advantage of the present process is that the ultrafiltrated ion-exchanged and concentrated permeate is so pure that for obtaining of almost pure beet sugar the crystallization does not need to be carried out in many stages and finally molasses is obtained as by-product. It is self-evident that the concentrated solution can be concentrated and/or cooled to saturation so that the sugar present therein crystallizes out but this opeation is not necessary for the purification. Delivery of pure concentrated sugar syrup is also important for economic reasons because there are many technical uses for sugar which start with a concentrated solution.
- Another advantage is that according to the present process no sugar-foreign substances should be added to effect specific reactions which substances should be removed again after the end of the reaction.
- the present process is namely carried out without the addition of any reaction component.
- decennia beet sugar is recovered from sugar beets with a sugar content of 16-19% by weight by extracting the sugar beets with water in the above described way, followed by roughly removing the pulp, treating the obtained product with lime and carbon dioxide for precipitating the pectins and albumins followed by removing the precipitate concentrating the obtained juice (thin juice) by evaporation, crystallizing sugar from the saturated solution and separating the crystallized sugar.
- Mangels or mangolds give the highest yield of beets per surface unit and also the highest yield of sugar per surface unit but the sugar content per beet is low so that such pulp will be obtained as by-product. Usually they are ripe very late so they have much foliage at the harvest time.
- beet species utilizes the water supply of the soil much better than other beet species. For that reason they are better resistent against long periods of dryness. With the same amount of water respectively nutritious substances they produce more dry material than sugar beets. However, for the recovery of sugar according to the known process they are not suitable because the amount of pulp which is obtained per weight unit of beets is considerably larger than when sugar beets are used as starting material and moreover the sugar content per weight unit of beets is much lower.
- Sugar beets possess a high sugar content but give less beets per surface unit than whis.
- the amount of foliage thereof is at the harvest time much less than that of the original Beta-vulgaris and the axes because they are ripe early.
- the first stage was fed with mush from the grater which was mixed with diluted cell juice from the second stage.
- the retentate contained proteins, pectins and gums which for instance were mixed with the obtained desugarized pulp and sold as cattle- fodder.
- the permeate was further purified by leading it over ion exchangers and treating it with decolorizing absorbentia.
- the mush from the grating apparatus of example I was desugarized and dewatered by means of a multi-stage counter-current washing in centrifugal sieves.
- the final retentate contained only 1 % by weight of sugar.
- the so purified permeate or filtrate with a mass of 900 kg contained 9.7% by weight of sugar (polarimetric) and 13.4 (w/w) % of dry material.
- the content of invert sugar was 5.4 (w/w) % on the basis of the dry material.
- This purified juice was then demineralized by means of subsequently a cation exchange resin and an anion exchange resin.
- This purified juice was almost colourless and contained only 5 (w/w) % non-sugar substances on the basis of the dry material content.
- This juice was concentrated in an evaporator to 71 (w/w) % dry material content.
- the white sugar obtained by crystallization was of excellent quality and was not second to other granulated sugar.
- This mush was then treated in the same way as described in example III.
- the pulp in the last stage was desugarized with 235 kg water of 9°C.
- the centrifugate of this fourth stage was used to desugarize the centrifugated pulp from the second stage. This was done in the third stage.
- the centrifugate was led to the centrifugated pulp from the first stage and the pulp from the third stage was led to the fourth stage.
- the mixture of centrifugates, coming from the third stage and pulp of the first stage were dewatered in the second stage.
- the juice from the second stage was joined with undiluted cell juice from the first stage. In this way a somewhat diluted cell juice (520 kg) was obtained, which was led to the ultrafiltration for the first purification with respect to proteins, gums and pectins.
