2. Description of the Related Art

Sorbitol catalytically hydrogenates glucose,
It is a typical sugar alcohol produced by pulverizing, has a refreshing sweetness with a cool sensation, and has a sugar content of about 70.
It has a sweetness of about%, is not easily assimilated by oral bacteria, and does not cause tooth decay, and it is difficult to be digested by human digestive enzymes, so we would like to prevent diabetes patients, obesity and tooth decay. Is widely used by people who are

Further, sorbitol powder is cheaper than powders of other sugar alcohols, has high stability against heat and the like, does not promote insulin secretion and has a favorable effect on absorption of various minerals. Since it has a useful function, it is not limited to the above-mentioned special use, but is widely used as a material for general foods, pharmaceuticals, cosmetics and the like.

On the other hand, various product forms of sugar such as granulated sugar, white sugar and brown sugar are known, and they are widely used for various purposes as a typical sugar.

In recent years, a mixed powder composition of sugar and sorbitol has been demanded mainly for economical reasons, but at present, it is produced by simply mixing sugar powder and sorbitol powder.

However, a product produced by simply mixing powders with each other has a tendency that components are biased due to vibration during transportation and the fluidity is low, which makes it difficult to automate the transfer and the like. However, there are problems such as variations in properties, tastes, and effects when used for various purposes.

In order to solve these problems, a granulation method of forming a film of sorbitol liquid on sugar powder has been proposed, but the resulting powder has a high hygroscopic property, and the cost for making sugar into a fine powder is low. It has not been put to practical use due to problems such as increased bulkiness.

Therefore, it has been desired to develop an economically advantageous manufacturing method while solving the problems such as the component bias.

In the fourth aspect of the present invention, the solid content concentration is adjusted to 76 to 80% by adding one or a mixture of water, sugar aqueous solution and sorbitol aqueous solution to the prepared musket. The method for producing a highly fluid mixed powder composition of sugar and sorbitol according to any one of the first to third aspects, which is adjusted to reduce the viscosity of the musket.

Furthermore, the fifth aspect of the present invention is the invention according to any one of the first to fourth aspects, wherein the first step and the second step are carried out continuously.

First, the first step according to the present invention will be described.

The sorbitol used in the present invention is required to have a quality for producing a sorbitol mass kit under the conditions of the present invention, but it tends to inhibit sorbitol crystal formation as mannitol having a similar molecular weight increases. , Mannitol and the like having a small amount of isomers are preferable, and a preferable sorbitol purity is 89.9 to 99.9% in the case of separately preparing a sorbitol mask and a sugar mask.

However, in the method of preparing a musket from a mixed aqueous solution of sorbitol and sugar in the present invention, sorbitol having a higher purity is required because of difficulty in crystal precipitation and the preferred sorbitol. The purity may be 95-99.9%.

The sugar used in the present invention is preferably a high-purity sugar having a quality that easily produces a sugar mass kit when the present invention is carried out, but commercially available granulated sugar, white sugar, coarse sugar, etc. are all 99 Since it has an extremely high purity of at least%, it can be advantageously used in the present invention.

One of the important points in carrying out the present invention is
The point is to prepare a sorbitol musket and a sugar musket, and in particular, in order to prepare a sorbitol musket which is advantageous in the practice of the present invention, the sorbitol aqueous solution is once heated to 100 ° C. or more to crystallize it. Concentration of 69 to 80%, preferably 76 to 7 after low saturation of less than 0.8 so that no embryo of
Adjust to 9%, add seed crystals if necessary, and stir while cooling to generate fine sorbitol crystals, and when the crystals are in the range of 5 to 35% in the aqueous solution, further The sorbitol mass kit advantageously used in the present invention can be obtained by stirring the mixture for about 5 to 10 hours while controlling the temperature so that the crystals do not grow and grow and maintaining the saturation at about 1.0.

In addition, when the sorbitol mass kit is prepared, many elongated crystals may be precipitated due to the effect of slow cooling, but when there are too many crystals or the crystals are too large and the viscosity becomes high. For the above, addition of water or an aqueous solution of sorbitol with sufficient stirring to reduce the solid content concentration can also be advantageously employed in transporting the mass kit and obtaining a spray-dried product with excellent quality.

When preparing a sugar musket, sugar has a high crystallization rate and tends to grow into single crystals. Therefore, an aqueous sugar solution concentrated to a solid content concentration of 75 to 85% is heated to 100 ° C. or higher. After decreasing the degree of saturation, seed crystals are added as needed, and fine sugar crystals are produced by stirring while cooling, etc., and the amount of crystals suspended in the aqueous solution is in the range of 5 to 35%. When the temperature reaches 1, the temperature is adjusted so that no more crystals are formed and grow, and the saturation is 1.
By stirring the mixture for about 5 to 10 hours while maintaining it at about 0, the sugar mass kit advantageously used in the present invention can be obtained.

Next, a method for preparing a musket from a mixed aqueous solution of sugar and sorbitol will be described.

In the case of this method, sorbitol having a purity of 95 to 99.9% is adopted, but a mixed aqueous solution having a solid content ratio of sorbitol and sugar in the range of 15:85 to 21:79 is prepared and the concentration thereof is 83 to. Concentrate to 87% and once at 100 ℃
By heating to the above to reduce the degree of saturation, then rapidly cooling to a temperature of 13 to 20 ° C., and adding a seed crystal of sugar and / or sorbitol as necessary while precipitating fine crystals while slightly stirring. A mixture kit can be obtained.

Next, the second step according to the present invention will be described.

When the sorbitol mass kit and the sugar mass kit are separately prepared and then introduced into the spray dryer,
Incorporation ratio of sorbitol mass kit is 10 to 2 in terms of solid content
1% by weight, the introduction ratio of sugar mass kit is 79-
Keeping the ratio of 90% by weight, mix both mass kits immediately before entering the spray dryer, or mix each mass kit into the spray dryer and then mix on an atomizer, etc. Is adjusted to a range of 30 to 85 ° C., preferably 40 to 75 ° C., and the solid content ratio of each component is adjusted to the above range to obtain a product having a relatively low hygroscopic property and a high fluidity. It is preferable for reasons such as satisfying the quality required by the market such as various compositions.

When spray-drying the musket prepared from the mixed aqueous solution of sugar and sorbitol in the first step according to the present invention, the solid content ratio of sugar and sorbitol is appropriately adjusted in advance in the aqueous solution stage. , The mass kit is introduced into the spray dryer as it is, and the blast temperature in the spray dryer is set to 3
The present invention can be carried out by controlling the temperature in the range of 0 to 85 ° C, preferably 40 to 75 ° C.

Further, the method of introducing the musket into the spray dryer is not particularly limited as long as it is a method adopted in ordinary spray drying, but a method in which an atomizer is provided above the spray dryer is used. The conditions are easier to control than the nozzle type, and when the air temperature is less than 30 ° C, the drying effect is insufficient and the water content may remain too much.
When a temperature exceeding ℃ is adopted, a glassy mixed solution of sorbitol and sugar may be formed in a large amount, or the powder once generated may be melted.

The spray dryer used in the present invention has a large diameter because the mass kit obtained by carrying out the present invention is difficult to spray-dry, and a product having high fluidity is obtained. Is preferred, but the specific diameter is 5
A meter or more, more preferably 8 meters or more can be advantageously used.

Further, as a result of carrying out the present invention, in order to obtain a good product with stable quality, adjustment is made so that a few percent of water is left when the powder falls to the bottom of the dryer during spray drying, The powder after spray drying is about the same as the exhaust temperature ~
A method of aging the crystal while maintaining it in a temperature range of about 60 ° C. can also be advantageously used.

As described above, since the process according to the present invention is completed in a relatively short time, there is no need for mechanically strong heating or strong kneading such as the kneader method, and a special structure having a complicated structure is used. It is an economically advantageous method because no special equipment is required, and the product obtained by passing through the method of the present invention has extremely high fluidity, and the components are biased due to vibration during transportation or storage. Therefore, there is an advantageous feature that the properties, tastes, effects, etc. do not vary when used for various purposes.

Further, the product obtained according to the present invention has a lower hygroscopicity than the conventional product, and therefore has an advantageous property that it is unlikely to cause solidification during storage.
