Definitions

  • a system for the production of sugar from sugar beets including devices and methods to transfer material from sugar beet juice.
  • Sugar beets contain sucrose, C 12 H 22 O 11 , a condensation molecule that links one glucose monosaccharide and one fructose monosaccharide.
  • the amount of sucrose produced by sugar beets can be dependent on the genetic strain, soil or fertilization factors, weather conditions during growth, incidence of plant disease, degree of maturity, or treatment between harvesting and processing.
  • Sucrose is concentrated in sugar beet root.
  • the sugar beet can be harvested and sugar beet juice containing a certain concentration of sucrose can be obtained from the sugar beet root by milling, diffusion, pressing, or other processing methods. Diffusion is perhaps the most common method for transferring sugar beet juice from the sugar beet root (hereinafter the term "diffusion" is intended to encompass any manner of removing sugar beet juice from the sugar beet root).
  • sugar beet root can be sliced or cut into smaller pieces, often thin strips referred to as cossettes (hereinafter the term “cossette” is intend to encompass any portion of the sugar beet root whether obtained from milling, cutting, slicing, or otherwise).
  • the sugar beet cossettes can be introduced into one end of a diffuser while a diffusion liquid, such as warm water, enters the other end.
  • This counter-current diffusion of sugar beet cossettes can transfer about 98 percent of the sucrose from the cossette to the diffusion liquid.
  • the diffused sugar beet juice mixed with the diffusion liquid is conventionally referred to as "diffusion juice" (hereinafter, unless otherwise indicated, the term "sugar beet juice” is intended to broadly encompass raw sugar beet juice, diffusion juice, or any subsequent process liquid derived from raw sugar beet juice during subsequent purification to sugar). Diffused sugar beet cossettes from the diffuser can still hold some sucrose containing sugar beet juice.
  • the diffused sugar beet cossettes can be pressed, in a screw press or in other types of presses, to squeeze as much sugar beet juice from them as possible.
  • This sugar beet juice often referred to as "pulp press water" which can have a pH of about 5 is often returned to the diffuser as part of the diffusion liquid. After pressing, the press pulp can still contain about 75% moisture.
  • pulp press water cationic charged pressing aids can be added to the diffused sugar beet cossettes during pressing. The addition of such pressing aids can lower the press pulp moisture content by about 1.5 to 2%.
  • Diffusion of sugar beet cosettes results in a sugar beet process liquid containing sucrose, non-sucrose substances, and water.
  • the type, kind, or amount of non-sucrose substances in sugar beet juice can vary and may include all manner of plant derived substances and non-plant derived substances, including, but not limited to: insoluble material, such as, plant fiber or soil particles; and soluble materials, such as, fertilizer, sucrose, or saccharides other than sucrose, organic and inorganic non-sugars, organic acids, inorganic acids, dissolved gases, proteins, phosphates, metal ions (for example, iron, aluminum, or magnesium ions), pectins, colored materials, saponins, waxes, fats, or gums, their associated or linked moieties, or derivatives thereof.
  • insoluble material such as, plant fiber or soil particles
  • soluble materials such as, fertilizer, sucrose, or saccharides other than sucrose, organic and inorganic non-sugar
  • Conventional sugar beet juice process systems further involve steps that increasingly clarify, purify, or refine sugar beet juice to obtain sugar.
  • a portion of the insoluble or suspended material in sugar beet juice can be removed using one or more mechanical processes, such as screening.
  • Screened sugar beet juice may contain about 82%-85% by weight water, about 13-15% by weight sucrose, about 2.0-3.0% by weight dissolved non-sucrose substances or impurities, and some amount of remaining insoluble materials.
  • floe is intended to broadly encompass any type of floe, aggregation of floe, aggregation of floe to a particle, precipitate formed, or other solid suspended in sugar beet juice) which can be removed by sedimentation, settling, filtering, or a combination thereof.
  • this step is often referred to as "preUming", however, the use of this term is not meant to limit use of the invention only to sugar beet juice process systems that utilize a preliming step. Rather, it should be understood that the invention can be used in a wide variety of sugar beet juice process systems in which it may be desirable to utilize base to raise pH of juice prior to a subsequent process step, such as a filtration step, as described by United States Patent Nos. 4,432,806, 5,759,283, or the like; an ion exchange step as described in British Patent No. 1,043,102, or United States Patent Nos.
  • base is intended to encompass materials that are capable of increasing the pH of sugar beet juice including, but not limited to the use of lime or the underflow from processes that utilize lime.
  • lime is intended to encompass the use of quick lime or calcium oxides formed by heating calcium (generally in the form of limestone) in oxygen and milk of lime which may be preferred in conventional juice process systems, and consists of a suspension of calcium hydroxide (Ca(OH) ) in accordance with the following reaction:
  • iso-electric point relates to the pH at which dissolved or colloidal materials, such as proteins, within sugar beet juice have a zero electrical potential.
  • dissolved or colloidal materials may form a plurality of solid particles, precipitates, flocculate, or floe.
  • floe may be an association of a core or substrate combined with other solid particles or flocculates in the treated sugar beet juice. This association can increase the size, weight or density of the floe facilitating settling or filtration and removal from sugar beet juice.
  • the resulting mixture of sugar beet juice, residual lime, excess calcium carbonate, and floe may further undergo "cold main liming" to stabilize the solids formed in the preliming step.
  • the cold main liming step may involve the addition of about another 0.3-0.7% lime by weight of prelimed sugar beet juice, or more depending on the quality of the prelimed juice, undertaken at a temperature of between about 30°C to about 40°C.
  • the cold main limed sugar beet juice may then be "hot main limed” to further degrade invert sugar or other materials that are not stable to this step.
  • Hot main liming may involve the further addition of lime to increase the pH of the sugar beet juice to between about 12 pH and about 12.5 pH. This can result in a portion of tl e soluble non-sucrose materials that were not affected by preceding addition of base or lime to decompose.
  • hot main liming of sugar beet juice may achieve thermostability by partial decomposition of invert sugar, amino acids, amides, and other dissolved non-sucrose materials.
  • the mam limed sugar beet juice can be subjected to a first carbonation step in which carbon dioxide gas can be combined with the main limed sugar beet juice.
  • the carbon dioxide gas reacts with residual lime in the main limed sugar beet juice to produce calcium carbonate in the form of precipitate.
  • residual lime typically about 95% by weight of the residual lime
  • the surface-active calcium carbonate precipitate may trap substantial amounts of remaining soluble non-sucrose substances.
  • calcium carbonate precipitate may function as a filter aid in the physical removal of solid materials from the main limed and carbonated sugar beet juice.
  • the clarified sugar beet juice obtained from the first carbonation step may then be subjected to additional liming steps, heating steps, carbonation steps, filtering steps, membrane ultrafiltration steps, chromatograpic separation steps, or ion exchange steps, as above described, or combinations, permutations, or derivations thereof, to further clarify or purify the sugar beet juice obtained from the first carbonation step resulting in a processed sugar beet juice often referred to as "thin juice".
  • This further clarified sugar beet juice or "thin juice” may be thickened by evaporation of a portion of the water content to yield a product conventionally referred to as "syrup". Evaporation of a portion of the water content may be performed in a multi-stage evaporator. This technique is used because it is an efficient way of using steam and it can also create another, lower grade, steam which can be used to drive the subsequent crystallization process, if desired.
  • the thickened clarified sugar beet juice or "syrup” can be placed into a container, which may typically hold 60 tons or more. In the container, even more water is boiled off until conditions are right for sucrose or sugar crystals to grow.
  • sucrose or sugar crystals Because it may be difficult to get the sucrose or sugar crystals to grow well, some seed crystals of sucrose or sugar are added to initiate ciystal formation. Once the crystals have grown the resulting mixture of crystals and remaining juice can be separated. Conventionally, centrifuges are used to separate the two. The separated sucrose or sugar crystals are then dried to a desired moisture content before being packed, stored, transported, or further refined, or the like.
  • a significant problem with conventional sugar process systems can be that non-sucrose substances within sugar beet juice can be highly colored, thermally unstable, interfere with certain sugar process steps, or adversely impact the quality or quantity of the sugar resulting from the purification of sugar beet juice. It has been estimated that on average one pound of non- sucrose substances in sugar beet juice can reduce the quantity of sugar resulting from a sugar beet juice purification process by one and one-half pounds. As such, it may be desirable to remove or separate, all of or a portion of, one or more of these non-sucrose substances from sugar beet juice prior to subsequent process steps.
  • a related problem with the production and use of base, such as calcium oxide, in conventional process systems can be disposal of excess base or of by products formed when base reacts with organic acids or inorganic acids in sugar beet juice.
  • base such as calcium oxide
  • sugar beet process systems use one or more carbonation steps in clarifying or purifying sugar beet juice, the amount of calcium carbonate or other salts formed, often referred to as "spent lime", will be proportionate to the amount of lime added to the sugar beet juice. Simply put, the greater the amount of lime added to the sugar beet juice, generally the greater the amount of precipitates formed during the carbonation step.
  • the "carbonation lime” may be allowed to settle to the bottom of the carbonation vessel forming what is sometimes referred to as a "lime mud".
  • the lime mud can be separated by a rotaiy vacuum filter, or plate and frame press.
  • the product formed is then called "lime cake".
  • the lime cake or lime mud may largely be calcium carbonate precipitate but may also contain sugars, other organic or inorganic matter, or water. These separated precipitates are almost always handled separately from other process system wastes and may have be slunied with water and pumped to settling ponds or areas surrounded by levees or transported to land fills.
  • the carbonation lime, lime mud, or lime cake can be recalcined.
  • the cost of a recalcining kiln and the peripheral equipment to recalcine spent lime can be substantially more expensive than a kiln for calcining limestone.
  • the quality of recalcined "carbonation lime” can be different than calcined limestone.
  • the purity of calcined limestone compared to recalcined carbonation lime may be, as but one example, 92% compared with 77%. As such, the amount of recalcined lime required to neutralize the same amount of sugar beet juice may be correspondingly higher.
  • Another significant problem related to the conventional use of lime in sugar processing systems may be an incremental decrease in process system throughput corresponding with an incremental increase in the amount of lime used in processing sugar beet juice.
  • One aspect of this problem may be that there is a limit to the amount of or rate at which lime can be produced or provided to sugar beet juice process steps.
  • limestone must be calcined to produce calcium oxide prior to its use as a base in juice process systems.
  • the amount of lime produced may be limited in by availability of limestone, kiln capacity, fuel availability, or the like.
  • the rate at which lime can be made available to the juice process system may vary based on the size, kind, or amount of the lime generation equipment, available labor, or the like.
  • Another aspect of this problem can be that the amount of lime used in the process system may proportionately reduce volume available for sugar beet juice in the process system. Increased use of base, such as lime, may also require the use of larger containment areas, conduits, or the like to maintain throughput of the same volume of juice.
  • Organic acids act as a buffering system in the acid-base equilibrium of the plant cell, in order to maintain the required pH value in the sugar beet plant tissue.
  • the origin of these acids can be divided into two groups, the first, are acids taken up by the plant from the soil in the course of the growing cycle, and the second, are acids formed by biochemical or formed by microbial processes.
  • plants may synthesize organic acids, primarily oxalic acid, citric acid, or malic acid, to maintain a healthy pH within the sugar beet plant cell.
  • sugar beet juice extracted from sugar beet root will contain a certain amount of various organic acids.
  • acids may be formed during storage primarily by microbial processes.
  • Badly deteriorating sugar beets may generate large amounts of organic acids, primarily lactic acid, acetic acid, as well as citric acid.
  • the total acid content within sugar beet plant tissue can increase threefold, or more, under certain circumstances.
  • carbon dioxide can be generated in sugar beet plant tissues due to breakdown of the natural alkalinity in the juice.
  • bicarbonate ion and carbonate ion are converted to carbon dioxide.
  • the resulting carbon dioxide to the extent it remains in the sugar beet juice generates carbonic acid.
  • Organic acids contained within the sugar beet plant cells, in whole or in part, remain with sugar beet juice obtained from the sugar beet plant material.
  • these organic and inorganic acids must be neutralized with base. The higher the concentration of organic acids or inorganic acids within the sugar beet juice, the greater the amount of base required to increase pH to a desired value.
  • sugar beets or sugar beet juice treated with antimicrobial chemicals can have higher acid content then untreated sugar beets or sugar beet juice.
  • sulfur dioxide (SO 2 ) or ammonium bisulfite (NH 4 HSO 3 ) can be added continuously or intermittently to help control microbial growth or infection.
  • the amount of SO added depends on the severity of the microbial growth or infection. Lactic acid and nitrite levels can be monitored or tracked to determine severity of growth or infection. Up to about 1000 ppm of SO? can be used to shock or treat an infected process system. Up to 400-500 ppm can be fed to an infected process system continuously to control an infection.
  • .HSO 3 used for antimicrobial protection can reduce pH and alkalinity of sugar beet juice.
  • Another significant problem with conventional sugar processing systems may be that materials contained in sugar beet juice, added to sugar beet juice during diffusion, or added during subsequent processing steps, may not be allowed to move toward equilibrium, or to the extent possible equilibrate with atmosphere, or other selected mixture of gases, or selected partial pressures of gases prior to pre-liming, or other subsequent process steps.
  • materials contained within sugar beet juice, otherwise transferable to atmosphere, or to other selected mixtures of gases, or selected partial pressures of gases remain in the sugar beet juice to, directly or indirectly, adjust or decrease pH of sugar beet juice.
  • diffusers do not provide, or provide an inadequate, gas-sugar beet juice interface from which materials in sugar beet juice can move toward equilibrium with atmosphere.
  • the provision of an inadequate gas-sugar beet juice interface can be exacerbated with the use of conventional tower diffusers where only a limited interface between diffusion liquids and atmosphere may occur at the top of the diffusion tower.
  • materials contained in the sugar beet diffusion juice such as carbonic acid, which can have sufficient vapor pressure to transfer from the sugar beet juice to atmosphere remain trapped within the sugar beet juice.
  • a second aspect of this problem may be that conventional sugar beet diffusers or diffusion methods do not provide sufficient re-circulation of atmosphere, or other mixture of gases, or other partial pressures of gases, at the gas-sugar beet juice interface to prevent saturation of gas responsive to the gas-sugar beet juice interface. Because gas saturated with transferable material does not allow transfer of additional material from the sugar beet juice, the desired, potential, or possible reduction of material from the sugar beet juice cannot be achieved.
  • a third aspect of this problem may be that conventional sugar beet diffusers or diffusion methods do not re-circulate the entire volume, or a sufficient volume, of the sugar beet juice to be present transferable material at the gas-sugar beet juice interface. If materials having sufficient energy to transfer from sugar beet juice are not brought to the gas-sugar beet juice interface transfer of the material cannot occur and the desired, potential, or possible reduction of material from the sugar beet juice cannot be achieved.
  • a fourth aspect of this problem may be that conventional sugar beet diffusers or methods of diffusion do not sufficiently heat sugar beet juice to a temperature that sufficiently increases vapor pressure(s) of material(s), or sufficiently reduces the solubility of material(s) in sugar beet juice, to result in a transfer such materials from the sugar beet juice; or to shift the point of equilibrium between such transferable material(s) and gas adjoining the gas-sugar beet juice interface to result in transfer of such materials, or reduce the amount of such material(s) in the sugar beet juice to the necessary, desired, potential, or possible concentration.
  • sugar beet juice may be allowed to cool and re-equilibrate, or partially re-equilibrate, with atmosphere, or other mixture of gases, or other partial pressures of gases.
  • atmosphere or other mixture of gases, or other partial pressures of gases.
  • concentration of gases, materials in equilibrium with such gases, or other materials in the sugar beet juice may increase as the sugar beet juice is allowed to cool during conventional processing steps.
  • solubility of atmospheric CO 2 increases as sugar beet diffusion juice cools from a temperature within the range of about 55°C to about 70°C to a temperature within the range of about 20°C to 30°C prior to sugar beet juice pre-liming or liming steps.
  • the increased concentration of CO 2 in the sugar beet diffusion juice forms carbonic acid reducing the pH of the juice.
  • the increased concentration of CO 2 ⁇ or other gases or materials transferred to the sugar beet diffusion juice may require additional amounts of lime or other base during pre-liming or other liming steps to achieve a desired or necessary pH.
  • atmosphere, or other mixture of gases, or other partial pressures of gases, presented at tlie gas- sugar beet juice interface may not volatilize, move, remove or otherwise allow transfer of a necày or desired portion of material(s) in the sugar beet juice, sugar beet diffusion juice, or other process liquid, to substantially increase pH of the sugar beet juice, or reduce the concentration of pH reducing materials in the sugar beet juice.
  • Another significant problem with conventional sugar processing systems may be that atmosphere, or other mixture of gases, or other partial pressures of gases, presented at the gas- sugar beet juice interface may not allow transfer of a necessary, or desired portion, of material in the sugar beet juice to substantially reduce generation of foam.
  • atmosphere, or other mixture of gases, or other partial pressures of gases, presented at the gas- sugar beet juice interface may not allow transfer of a necessary, or desired portion, of material in the sugar beet juice to substantially increase the rate of floe formation, size, density, or settling rate, during pre-liming, liming, or carbonation steps.
  • atmosphere, or other mixture of gases, or other partial pressures of gases, presented at the gas- sugar beet juice interface may not allow transfer of a necessary, or desired portion of material in sugar beet juice, including, but not limited to, volatile organic compounds; volatile inorganic compounds; volatile acids; volatile bases; a gas; acetaldehyde; ethanol; acetone; ammonia, dimethylsulfide; 2-propenenitrile; methyl acetate; isopropanal; 2-methyl propanal; methacrolein; 2-methyl-2-propanol; propanenitrate; 1-propanol; 2-butanone; 2,3-butanedion; ethyl acetate; 2 butanol; methyl propanoate; 2- butanal; 3-methylbutanal; 3-methyl-2-butanone; isopropal acetate; 2-methyl butanal; 1-butanol, 2-butenenitrile; 2-pentanone; 2,3
