An object of the present invention is to provide a method for producing sugar and ethanol from sugar cane, in which almost all of energy to be consumed in the production processes of the sugar, the ethanol and the like can be supplied by the energy obtained by burning a pressed residue of sugar cane, yet without decreasing the sugar amount to be produced. The present invention provides a method for producing sugar and a useful material from sugar cane, comprising the steps of: (a) producing from sugar cane a pressed juice and pressed residue of sugar cane; (b) producing sugar and blackstrap molasses from said pressed juice; and (c) generating an energy and a useful material by using said pressed juice, said blackstrap molasses and said pressed residue of sugar cane as source materials that have been obtained from said steps (a) and (b), wherein said sugar cane contains an amount of 15% or greater by mass of fiber component in its cane stem region and provides a dry matter yield amount per unit area of 40 t/ha/year or higher; and 90% or more of energy required for all of the steps of said production method is obtained from energy generated by burning said pressed residue of sugar cane.

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.

Methods are described for producing sugar from sugar-containing plant material with microbiological control, which includes treating a sugar-containing plant raw material and/or a component derived therefrom, and/or a medium containing the plant raw material and/or the component, with monochloramine. Monochloramine usage in the method can reduce loss of sugar from bacterial consumptions in the processing of sugar-containing plant materials, such as sugar beets, without causing adverse effects on the sugar product, such as the brightness of white sugar.

A process is proposed for recovery of water in the sugar cane processing in production mills of sugar and alcohol or only alcohol (ethanol). In the process, the thermal energy available in the exhausted steam from the electric energy generation turbines is transferred to the different mixed juice processing phases, with the reuse of the exhausted steam condensates in the boilers and of the other condensates, after using thermal energy, for imbibition, in the juice extraction phase, for cooling in the process, after passing through cooling towers, for other industrial uses and for possible treatment or use in the irrigation out of the productive system in the mill

A process (10) and apparatus (2) for extracting juice from a fibrous material. The process (10) comprises a step of feeding the fibrous material (13) into a receiving chamber (30) having a fluid contained therein. The fibrous material (13) is then combined with the fluid in the receiving chamber (30) to form a first fluid mixture. The first fluid mixture is then passed through at least one cell disruptor device (40) to facilitate at least partial release of juice from the fibrous material into the first fluid mixture, thereby forming a second fluid mixture having a relatively higher released juice content than said first fluid mixture with relatively finely disrupted fibrous material suspended therein. The second fluid mixture is then collected.

The cane juice extractor includes a wagon that may be hitched to or towed alongside a harvesting machine or combine for application in-field. The wagon includes a frame having an upper deck and a lower deck. The upper deck includes an inlet side where harvested cane may be fed for juice extraction and an outlet side for disposing the pulp. Rotating feeders feed the cane to a cutting station on the upper deck. The cutting station comminutes the cane into billets that are carried by an endless belt through a series of compression roller sets. Each set of rollers compress the cut cane down to smaller dimensions to extract the juice. A chute disposed between the upper and lower decks collects the juices and funnels them into a juice storage tank on the lower deck. The pulp is expelled from the outlet side to the field.

The portable sugar mill is established on a mobile platform for transport to the harvesting field, so that the juice of the harvested sugar cane may be processed and refined in the field. The portable sugar mill converts the juice, which contains sucrose, into raw sugar crystals (brown sugar) and molasses. The portable sugar mill includes a separator tank, a pre-heating tank, a clarifier, and three successive stages of evaporative crystallization and separation of crystals from syrup. The portable sugar mill has a programmable logic controller and a plurality of sensors, control relays, pumps, motors, heaters, and valves that operate automatically under direction of the programmable logic controller.

The presently disclosed subject matter relates to processes that comprise the vacuum extrusion of plant materials. In some embodiments, the plant materials are subjected to a change in pressure of −3 kPa or more.

A drive means is arranged to move the longitudinal transport zone at a first speed towards the outlet end of the diffuser and to retract the longitudinal transport zone at a second speed which is substantially faster than the first speed towards the inlet end of the diffuser, so that the transport zone drive the product towards the outlet of the diffuser.

The present invention relates to a crushing system with two rotating disk sections which allows applying high pressures without the problem of raw material rejection and with a reduced number of crushing cycles, thus shortening the crushing time. Pressure is gradually distributed between the two similar rotating disk sections which are arranged face to face and connected to non-aligned shafts, such that the lower sides of the disk sections remain always joined. The disk section mounting assembly is independent and has different features, forming a fixed part and a movable part for adjusting the vegetable mass being compacted. This crushing system has structural features that allow different uses (in isolation, in tandem or in combination), and the serial combination thereof in appropriate industrial infrastructures or in harvesters of standing crops, such as sugar cane.

The invention discloses a low-frequency high-energy ultrasonic-coupled fluidized beet-exudating method and device. Three or more large-amplitude ultrasound transducers are assembled into a group and sealed inside a box body to manufacture a plate-type immersed ultrasonic extracting device, wherein the plate-type immersed ultrasonic extracting device resonates at the same frequency to form a single-sided radiator so as to achieve a quick and efficient exudating process. The method and the device can shorten the exudating time and reduce the water consumption and the workload of an evaporating working section, thus reducing the coal consumption and the steam consumption and achieving aims of saving energy, protecting environment and improving the production efficiency.

The inventive method consists in forming nonsucrose precipitates during a sucrose extraction process in a diffuser by binding nitrogen-containing and nonnitrogenous high-molecular nonsucroses and colloidal dispersion agents, deposing nonsucrose precipitates on beet cossets and in removing them from a diffusion juice with a beet pulp, aggregating nonsucrose dispersed particles in the diffusion juice neutral-acid medium, flocculating said particles and removing them together with a precipitate by filtering or separating, defecating a filtrate, coagulating and flocculating a defecated juice nonsucroses in an alkaline medium, separating the precipitate, neutralising the purified juice, thickening it and in boiling a fillmass. The method uses in said production process the synergism of the interaction of inorganic coagulants of metal salts solutions and organic flocculants of synthetic polymers, thereby making it possible to substantially improve the purity of sugar-containing solutions and to reduce a production process at a lime/carbon dioxide purification plant.
