Definitions

• This invention refers to a process for the obtention of carbo hydrates, derived from vegetal raw material, thus fitting in the technical sector of the industrial production of carbon hy drates.
• the large scale production of carbohydrates proceeds along the following overall line: initially, the raw-material passes in machines that mechanically remove the juice followed by thermic precipi tation, passing to the vacuum concentration and crystallization, ending with the separa-tion of the solid and liquid stages. Practically, all the production of carbohydrates, the condensation ones of high molecular weight, and those of three, five and six carbons, leads to the obtention of the best utilized soluble form: the alfa-delta-glucopyranosis .
• figure 1 shows the overall flow chart of the conventional procedures currently used in industrial chemistry
• figure 2 shows the flow chart of the actual process.
• figure 1 we observe an (1) expeller where the juice is extracted by any pressure procedure, by cylinder or diffusion; the filters (2) with a wire grid where the extracted juice is strained to remove the gross material in suspension; the heaters (3) where the juice is cleaned by heat, chemical coagulants and even ionic exchange; the plate heaters (4) to increase the extracts temperature; the vacuum concentrator batteries (5) where most of the water is eliminated; the so lidifiers unit (6) where, after passing again through plate heaters (4) solids are separated from the liquid, forming a mixed paste, ending the process in the centrifugal separators (7) , where solids are finally separated.
• Figure 2 shows that, in the current process, some of the heaters (3) the centrifugal separators (7) and some plate heaters (4) are excluded whereas the other conventional components remain.
• the proposed procedure acts on the extracts, creating controlled conditions that induce directions on the dynamics of the reactions, which are able to complete nature's action; it acts on pre-established substrates, enabling the obtention of a, specific and defined product that basically maintains all the initial components, as only the reactions that were interrupted in the so called "relative vegetal cycle" are completed.
• the diffuser (1) With the diffuser (1) the extract or juice is obtained were the dissolved carbohydrates are found; there is no need to control the pH, as the vegetal extracts are in the 3 , 5 and 7 range were the proposed enzymes act and the reaction times vary Iran 20 to 90 min. Temperature should remain at 18C to 67C-To simplify the enzymes that should be added are listed below, by the number corresponding to their international classification, and in the present case they vary from 3.2.1.1 (4-glucan-4-glucanhy drolase) to 5.3.1.5 (xylose-ketol-isomerase) ; during the reactions:
• the enzyme unit is the quantity able to hydrolize in 10 min. one mol of starch.
• the temperature in the heaters (3) is raised to 90/100C to clot all impurity that remains and the albuminoids, then proceeding to a filtration or centrifugation to obtain the clean syrup around 130Brix; the syrup is led to the vacuum concentrators (5) to eliminate practically all water, at a temperature not beyond 70C around 709Brix.
• the product is mixed at low speed in the crystallizers (6) till the granules separate by themselves.
• the end product must have a relative humidity of less than 0,50%, preferrably at 0,25%.
• the obtained concentrate is composed of carbohydrates without liquid stage.
• the process permits, as an option, that, the concentrate be sent to a spray-dryer to form an even powder or granulate to be used directly or for further industrial use in types of reactions mentioned previously. Among the process' advantages one might mention:
• the end product obtained by the current process has a range of applications; as human nourishment because it possesses besides high rates of sugars, around 92%, mineral salts, essential and non essential amino-acids, vitamins, etc. as nourishment for animals and for industrial scopes it is efficiently used as raw material for the process of alcoholic, glutamic, acetic, fermentation and also the production of a large range of products.
• the process, object of the current invention has, among others the following advantages: a) reduces industrial costs (30% in machinery and equipment) b) increases production attaining integral sugar, 50% per ton of sugar cane with Pol 88, as it does not use chemicals. Further with this enzymatic process a natural sugar is obtained totally in solid state, in a sole phasis, without wastes or secondary carbohydrates. Therefore, the following application for patent, presents a great innovation and the product (s) obtained possess by far superior characteristics to the conventional ones.
