Method and apparatus for producing honey-containing sugar

  The present invention relates to a method and an apparatus for producing powdered or liquid honey-containing sugar made from sugarcane.

  Brown sugar produced mainly in Okinawa as a traditional honey-containing sugar that has a unique flavor not found in general white sugar and granulated sugar, which is industrially produced and widely used in modern large-scale factories, Wasanbon sugar produced mainly in Shikoku is known.

  Brown sugar is produced by heating the compressed juice obtained by squeezing sugar cane, adding lime and removing ash juice, etc., boiling the clear juice into concentrated sugar juice, cooling and solidifying it. It has a rich and unique flavor and is popular as a sweet taste product that is mainly eaten as it is.

On the other hand, in the case of Wasanbon sugar, the juice obtained by squeezing sugarcane on the stems called bamboo sugar is heated, and the clarified juice obtained by adding lime and removing the ash is boiled to obtain concentrated sugar juice, which is then cooled. The crystal sugar obtained is crushed to obtain white sugar. After adding water to this white sugar, knead it to make it familiar (sharpening), and then manually repeat the honey treatment to put out the molasses containing impurities by putting it in a filter bag and pressurizing it. It is a pale yellowish white honey-containing sugar, has a unique and elegant flavor, and is prized as a raw material for famous confectionery and confectionery.

  There is a high demand for food producers who want to use the unique flavors of these traditional honey-containing sugars in various foods, etc., but they are manufactured by handicraft methods, so there are problems in terms of productivity and hygiene. Not yet satisfied.

As for brown sugar, because it is produced by inefficient cleaning process called precipitation operation by lime and gravitational settling, purity is low contains a large amount of impurities such as foreign matter and bacteria. Accordingly, there is a problem in terms of hygiene and quality stability when used as a raw material for mass-produced foods where quality adjustment between products must be strictly performed. Furthermore, brown sugar must be a block or coarse grain product due to the manufacturing process. For this reason, there is also a problem that it cannot be used as it is for food raw material applications where the use of liquid saccharide-containing sugar is suitable.

  With regard to Wasan Bon Sugar, it is necessary to repeat the “sharpening and pressing process” manually by hand, so it can take many days to complete, so it cannot be produced in large quantities. Therefore, the price is extremely expensive, making it difficult to use for mass-produced products. In addition, since Wasanbon sugar is in the form of powder as well as brown sugar, there is a problem that it cannot be used as it is for food raw materials for which liquid honey-containing sugar is suitable.

  Therefore, the main problem of the present invention is that the high-quality powdered and sugar-containing saccharides that leave the unique flavor and mineral nutrients derived from sugar cane are hygienically (no foreign substances and bacteria mixed) and industrial It can be mass-produced and can be adjusted in a wide range of quality from brown sugar to high quality powdered honey containing sugar according to the needs of end users.

Therefore, by adjusting the purity (crystallizing condition) of crystal sugar, or by appropriately changing the mixing ratio of dissolved sugar liquid and crude concentrated juice, quality from brown sugar quality to Wanbon sugar quality or higher Can be easily produced without changing the production equipment.

  Alternatively, the crude concentrated juice may be collected as it is, or a mixture of crystal sugar, molasses separated in the crystallization process of the crude concentrated juice used in the crystallization treatment step and the crude concentrated juice may be collected to obtain a liquid Can be obtained. As for this liquid sugar-containing sugar, it is possible to obtain an unprecedented quality by adjusting the mixing ratio.

  In the present invention, it is possible to perform industrial production that is completely automated without requiring manual work by hand, and mass production of high-quality powdery or liquid honey cane sugar is possible at low cost.

  Next, embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a flow diagram of a process for producing powdered honey sugar and liquid honey sugar according to the present invention.

The sugar cane is cut with a cutter and further shredded with a shredder, and then supplied to the subsequent coarse juice production process by a conveyor for transportation. In the coarse juice production step, the crude juice is obtained by squeezing by a known squeezing method. The crude juice may be obtained by a known extraction method, or a mixture of a pressed juice obtained by pressing and an extracted juice obtained by extraction may be used. In the squeezing treatment, it is desirable to perform the treatment with an emphasis on the purity of the extracted sugar solution rather than the sugar extraction rate, and it is appropriate to secure 80 to 90% as the squeezing rate. Therefore, it is appropriate to squeeze in a triple mill instead of a quadruple to 6-fold mill in a normal raw sugar factory. Since pure sugar content of sugar solution obtained as subsequent mill decreases in multiple mill, so as to obtain a high quality sugar juice to increase the ratio of the obtained that molasses from first issue mill. It is desirable that bagasse, etc. generated as squeezed residue is returned to farmers as animal feed and bedding for effective use.

  Usually, the pH of the obtained crude juice is around 5-6, and under this situation, the sucrose content in the crude juice is hydrolyzed and converted into reducing sugar, so that it is limited in the latter stage from the viewpoint of improving the quality of the product. Before the outer filtration treatment step, it is desirable that lime, caustic soda, sodium carbonate or the like is appropriately added to the crude juice to adjust the pH of the crude juice to 6 to 7.5 to suppress reducing sugar production.

  On the other hand, in the coarse juice, sugarcane-derived fibrous substances (also referred to as “pis”), sand, sand and other foreign matters (hereinafter also referred to as “insoluble impurities”) are mixed. In addition, a prefiltration treatment for removing these insoluble impurities is performed. A screen treatment is suitable for the prefiltration treatment.

As the screen, a fixed inclined wedge wire screen is suitable because it can be continuously discharged and has no moving parts and is easy to operate. The performance of the screen may be appropriately determined in consideration of the composition in the crude juice. When the subsequent filtration membrane has a spiral structure, it is necessary to consider the clogging between the slits. Therefore, a screen having a performance capable of removing insoluble substances of 50 μm or more is suitable. If the subsequent ultrafiltration membrane is a tubular type, it is unlikely that the liquid flow path is clogged. Therefore, the screen is appropriately selected in consideration of the concentration ratio and the removal rate of piss. The screen may be arranged in two stages, for example, the first stage may be cut by 100 to 300 μm, and the second stage may be cut by 50 μm. In this case, the film processing load in the subsequent process is further reduced. Further, check filtration may be added to the final stage of the preliminary filtration treatment.

  The pre-filtered crude juice is preferably heated to improve membrane permeability (decrease in sugar solution viscosity) and improve concentration efficiency in the subsequent membrane filtration treatment. The extent to which the crude juice is heated may be appropriately determined in consideration of the temperature specification of the subsequent filtration membrane, but is preferably about 50 to 80 ° C. It is preferable to use low-pressure steam (0.1 to 0.2 MPaG) as a heating source and a plate-type heat exchanger for maintaining the flavor of the product and improving efficiency.

  When the crude juice is heated, it is subjected to membrane filtration using a filtration membrane to separate and remove fine suspended solids and polymer impurities in the crude juice. The membrane filtration treatment also removes general bacteria that lead to a decrease in product quality, including precipitated components. In the membrane filtration treatment, a concentrated waste liquid containing a large amount of impurities is obtained together with the clarified juice supplied to the subsequent stage, and it is desirable to recycle this concentrated waste liquid as a fertilizer together with the residue of the preliminary filtration treatment.

  The membrane filtration treatment is suitably a cross flow type continuous membrane filtration treatment. You may divide | segment and process into the multistage film | membrane process which raises a concentration ratio sequentially. The membrane area can be reduced by concentration in several stages. The determinant for dividing the membrane treatment into several stages is determined by the membrane treatment ability at each concentration ratio. In addition, by irrigating water, the effect of diafiltration is obtained and the concentration of insoluble suspended solids is reduced, so that the recovery rate of sugar solution can be increased.

The membrane used for the membrane filtration treatment can be appropriately selected from known separation membranes such as an ultrafiltration membrane and a microfiltration membrane. The specification relating to the temperature resistance of the filtration membrane may be appropriately selected in consideration of the temperature of the crude juice, and specifically, it is desirable that it can be used at 50 ° C. or higher, preferably 80 ° C. or higher. The film structure and film material are not particularly limited. In view of the removal of fungi in the crude juice and the improvement of productivity, which are the objects of the present invention, an ultrafiltration membrane having a fractional molecular weight of about 30,000 to 100,000 and an operating pressure of about 3 to 5 kgf / cm ² G is particularly suitable. It is.

  The clarified juice obtained by the membrane filtration treatment is pre-concentrated to a target concentration (Brix: hereinafter abbreviated as Bx) to obtain a crude concentrated juice. In the preconcentration process, a multi-effect can with high thermal efficiency is advantageous. As the concentrator, a Calandria type can be used, and the thickening material is removed by membrane filtration treatment. Therefore, a plate type heat exchanger with high heat exchange efficiency, a falling liquid film type heat exchanger Can be used.

  A part of the crude juice is used for crystallization to obtain crystal sugar. Crystallization treatment is a known crystallization method in which crude concentrated juice is cooked under vacuum to crystallize the sugar in the crude juice, and then subjected to solid-liquid separation with a centrifugal separator or the like and washing treatment to obtain crystal sugar. It can be a process. For such crystallization treatment, a known crystallization equipment used for crystallization treatment of ordinary raw sugar or purified sugar can be used. In the crystallization treatment, it is preferable to obtain crystal sugar having a purity of 98% or more by an appropriate operation such as a separation operation.

  The obtained crystalline sugar is redissolved and mixed with the crude concentrated sugar juice at an arbitrary ratio to obtain a mixed sugar juice of arbitrary purity. In obtaining a product, it is preferable that the mixed sugar juice has a purity of 92% or more.

  The obtained mixed sugar juice is finished and concentrated to obtain concentrated sugar juice. The final concentration is concentrated by boiling until it reaches a concentration range where cooling crystallization is possible, specifically, Bx95 or more. The operation is preferably a continuous thin-film concentrator in order to prevent a decrease in flavor, alteration or decomposition, but a batch-type concentrator (pot) may also be used.

  The concentrated sugar juice obtained by finishing concentration is solidified and powdered to form powdered honey sugar. Since the concentrated sugar juice is in a supersaturated state, it is partially dried by stirring and cooling and solidified into a powder. It is to be noted that a homogeneous powder can be obtained by removing or crushing lumps generated at this time with a sieve. Cooling and drying are preferably performed by a multistage stirring device in which three stages of mixing / cooling machines having ribbon blades or paddle blades are arranged in succession. In order to prevent the occurrence of mold from powdered saccharide-containing sugar, it is desirable to adjust the moisture by drying to the desired moisture in a dryer. The moisture content may be determined appropriately depending on the required sugar product. It is desirable that the water content is low, but 4.0% by weight is not required. In addition, the powdered honey-containing sugar obtained is superior in quality by removing lumps with a sieve or by appropriately pulverizing / disintegrating with a pulverizer or a pulverizer so that lumps are not mixed when commercialized. Powdered honey sugar can be obtained.

  On the other hand, in the present invention, the crude concentrated juice can be collected and used as it is as liquid saccharide-containing sugar. In addition, the molasses separated from the crystalline sugar in the crystallization process of the crude concentrated juice subjected to the crystallization treatment process is mixed with the crude concentrated juice not subjected to the crystallization treatment process, and collected to obtain a liquid molasses sugar. You can also These liquid saccharides are obtained from crude concentrated juices that have been subjected to membrane filtration treatment and fungi are separated and removed. Therefore, these liquid saccharides are sanitary liquid saccharides that can be used for various foods. is there.

  In the present invention, although the fungus removal treatment is performed as described above, the liquid honey sugar is more susceptible to external fungi and the like than the dry powdery honey sugar. More advanced quality control is required. For this reason, in concentrating, diluting, or storing, it is preferable to take thorough measures against contamination of bacteria such as sterilization and germicidal lamp. In addition, various measures for preventing contamination and preventing bacterial growth are implemented, and in order to enable long-term storage, it is suitable to store in a storage tank with a temperature adjustment function and store it indoors.

Based on the flowchart shown in FIG. 1, the content of the present invention was verified.

Mill was squeezed using a test mill to obtain 152 kg of crude juice having a concentration (Bx) of 21 and a pure sugar ratio of 88.3%. The squeeze rate was about 90% with emphasis on purity. Thereafter, the coarse juice was passed through a 300 μm wedge wire screen to separate and remove insoluble impurities. Thereafter, lime milk of 15 ° Be was gradually added to adjust the pH to a range of 6.5 to 7.5 and left for a certain period of time to sufficiently settle the SS component, and the supernatant was recovered.

The supernatant is kept at a temperature of 55 to 60 ° C. and then subjected to membrane filtration with an ultrafiltration apparatus equipped with an ultrafiltration membrane having a filtration area of 0.5 m ² and a molecular weight cut off of 50 KD.

As a result, 132.3 kg of clarified juice, 20.5 clarified juice concentration (Bx), 18.8 kg of concentrated waste solution, 22 concentration of concentrated waste solution (Bx), and 8 times concentration ratio Results were obtained. This is a sufficiently practical result.

Next, the clarified juice obtained by the membrane filtration treatment was put into a concentrated can of a concentrated can size: 250 mmφ × 1330 mmH, heating transmission surface: 0.47 m ² , heated under vacuum to evaporate water, and the concentration ( Bx) to 72 to obtain a crude concentrate. The operation conditions of the concentration can were as follows: the amount of the applied liquid: 28 L, the operating pressure: about 118 torr, the operating temperature: 60 ° C., and the steam pressure: 2 kg / cm ² G.

  Under the above operating conditions, 132.3 kg of clarified juice having a concentration (Bx) of 20.5 was pre-concentrated, and then 31.3 kg of crude concentrated juice, 72.0 of crude concentrated juice (Bx), and concentration ratio: 4.2 times. Results were obtained. Further, when the quality of the crude concentrated juice was analyzed, the concentration (Bx) was 74.0, the sugar content was 65.34%, the pure sugar rate was 88.29%, the invert sugar rate was 1.12%, and the color value (Stamer Color Value) Good, hereinafter abbreviated as SCV.) A result of 194 was obtained. This is a sufficiently practical result.

  Next, 15.7 kg of the obtained crude concentrated juice is crystallized under vacuum using a crystal can, and the resulting slurry is subjected to solid-liquid separation using a centrifuge and remains on the separator basket. Warm water was sprayed onto the crystal cake to remove the honey content adhering to the crystal surface to obtain 5.63 kg of high-purity crystal sugar. When the quality of the crystal sugar was analyzed, the sugar content was 98.88%, the pure sugar ratio was 99.6%, the invert sugar ratio was 0.02%, the water content was 0.74% by weight, the ash content was 0.041% by weight, and the color value (SCV ) A result of 3.95 was obtained.

  Thereafter, the high-purity crystalline sugar was dissolved in warm water to a concentration (Bx) of 72 to obtain 7.8 kg of a dissolved sugar solution. This dissolved sugar solution with the concentration (Bx) 72 and the crude concentrated juice with the concentration (Bx) 72 are mixed at a ratio of 5: 2, separated into metal balls, and heated and finished with a stove for concentration. Thus, concentrated sugar juice having a concentration (Bx) of 96 was obtained. Because of the high concentration (Bx), the degree of concentration was controlled by temperature, and the temperature was 115 to 130 ° C.

  The concentrated sugar juice obtained by the finish concentration treatment was dropped from the stove together with a metal bowl, stirred and mixed with a wooden spatula while allowed to cool naturally, and crystallized to obtain coarse powdered honey-containing sugar. Further, the coarsely powdered honey sugar was dried for 1 hour in an air bath maintained at 70 ° C., and further pulverized in a mortar to obtain a homogeneous pulverized honey sugar. This powdery honey-containing sugar had a pale yellowish white color. In addition, 5 kg of powdered honey sugar was able to be obtained with respect to 8 kg of mixed concentrated sugar juice.

Sufficient quality. The powdered sucrose containing sample 2 also showed a pale yellowish white color.

  The taste of the powdered honey sugar according to Sample 2 and the powdery honey sugar and brown sugar according to Sample 1 prepared in Example 1 were tested. As a result, brown sugar had a unique and rich flavor. The powdered honey sugar according to Sample 1 and the powdered honey sugar according to Sample 2 had no sweetness like brown sugar and had a refined sweetness and fragrance like Japanese sanbon. In addition, the powdered honey sugar according to sample 2 was more strongly perceived as sugarcane-derived flavor than the powdered honey sugar according to sample 1. It was also shown that the ratio of the crude concentrate to the dissolved sugar solution caused a change in flavor.

  In addition, the presence of powdered honey sugar according to Sample 2, the powdered honey sugar according to Sample 1, the crude concentrated juice and brown sugar of these raw materials, and the presence of common bacteria and mold / yeast were examined. As a result, 400 bacterium / g of general bacteria were detected for brown sugar and 10 bacterium / g for mold / yeast, whereas 0 / 2.5 g for general bacteria and mold / yeast were used for crude concentrate. As for the powdered honey-containing sugars on Samples 1 and 2, the results were 0 / 0.5 g for both general bacteria, molds and yeasts. It was shown that the product of the present invention has significantly less (not) the content of common bacteria, molds and yeasts compared to brown sugar.

  As described above, Examples 1 and 2 indicate that according to the production method of the present invention, it is possible to produce a large amount of sanitary and industrially large amounts of honey-containing sugar that leaves a flavor derived from the raw material.

  In addition to the field of producing hygienic and industrial mass production of powdered or liquid honey-containing sugar that leaves flavors derived from various natural materials, the present invention uses honey-containing sugar that leaves flavors derived from various natural materials as raw materials.
