In addition, the water-containing raw material is a mixture of water and solids in all degrees from an aqueous solution in which a substance is completely dissolved to a substance in which an insoluble component is dispersed in an aqueous solution of the substance, and further only an insoluble component is dispersed in water. Points to the state. Moreover, the mixing ratio of solid content and water is also arbitrary, and includes a mixture having a high concentration enough to lose fluidity from a mixture of a small amount of substances. Further, liquids containing substances other than water are also included.

  Furthermore, in a method for producing a powder article by spray drying from a hydrous raw material containing a hygroscopic component, adding ethanol and a powdered base material to the hydrous raw material and spray drying is a means for solving this problem. It was set as the 2nd aspect.

  In the method of pulverizing a raw material containing a hygroscopic component by the present inventor, the original quality of the powder material is not impaired, the process is not complicated, and there is little adhesion to the manufacturing equipment during spray drying. In addition, with the aim of providing a method for improving the physical properties of powdered articles to obtain a powder having excellent fluidity and anti-caking property, the effects of the means provided to solve the problems are as follows. is there.

  First, in the present invention, that is, a method for producing a powder article by spray drying from a water-containing raw material containing a hygroscopic component, the water contained in the water-containing raw material is added to the water-containing raw material and spray-dried to add the water contained in the water-containing raw material. The energy required for vaporization is reduced because a part of the mixture is mixed to form an azeotropic mixture, and a part of the substance dissolved in moisture is eliminated by ethanol, and the rise in molar boiling point is alleviated. As a result, the volatilization of moisture is facilitated and the effect of facilitating the drying can be obtained. As a result, the moisture content of the powder is quickly reduced, and the powder is less likely to adhere to the production facility, and a powder having excellent fluidity and anti-caking property can be obtained.

  If the amount of ethanol added is 0.1% by weight or more and 10% or less of the undiluted solution before spray drying, it is less likely to adhere to production equipment during spray drying, and it is excellent in fluidity and anti-caking property. Powder can be obtained.

  Furthermore, in the method for producing a powder article by spray drying from a water-containing raw material containing a hygroscopic component according to the present invention, in addition to adding ethanol to the water-containing raw material, a powdered base material is also added and spray-dried; According to the invention, by adding the powdered base material, the hygroscopic component is included in the powdered base material in the drying process and in the powder state, and the association of the hygroscopic component is inhibited to form a stable agglomerate. In addition, there is little adhesion to the production equipment, and the effect of obtaining a powder having excellent fluidity and anti-caking property is obtained. In addition to this, the above-mentioned effect of adding ethanol is added, and the effect is further enhanced.

  When the addition amount of the powdered substrate exceeds 5% by weight, an effect that adhesion to the spray drying equipment is reduced is obtained. Further, when the content is 10% by weight or more, a powder article having more excellent fluidity and anti-caking property can be obtained. However, when it exceeds 90% by weight, an adverse effect on the flavor of the product powder appears. Moreover, by making it less than 70 weight%, the powder article excellent in fluidity | liquidity and anti-caking property can be obtained more economically. Therefore, by making the addition amount of the powdered base material 5% by weight or more and less than 90% of the total amount of the solid solution before spray drying, the original quality of the powder material is not impaired, and the process is not complicated, It is possible to suitably obtain a powder with less adhesion to the production equipment during spray drying, and excellent fluidity and anti-caking property. Thus, a desired powder can be obtained.

  By using any one or more members selected from the group consisting of starch, modified starch, dextrin, and cyclic dextrin as the powdered base material, stable agglomerates are formed, and the original quality of the powder material is not impaired. It is possible to suitably obtain a powder that does not complicate the process, has little adhesion to production equipment during spray drying, and is excellent in fluidity and anti-caking property.

  When the water-containing raw material containing the hygroscopic component contains any one or more of the group consisting of monosaccharides, disaccharides, and polysaccharides, the conventional method improves adhesion to the spray drying equipment. Spray drying is required, and quality degradation such as browning or scorching of sugars may occur. However, by using the above-described method using ethanol, there is an effect that even when spray drying at a lower temperature, adhesion to the spray drying equipment is reduced, and quality deterioration is less likely to occur.

  Even when the water-containing raw material contained in the hygroscopic component contains amino acids, the conventional method requires spray drying at high temperature to improve adhesion to the spray drying equipment, resulting in quality degradation such as browning and scorching of amino acids. May occur. However, by using the above-described method using ethanol, there is an effect that even when spray drying at a lower temperature, adhesion to the spray drying equipment is reduced, and quality deterioration is less likely to occur.

  Finally, the original quality of the powder material obtained by the present invention is not impaired, the process is not complicated, the adhesion to the production equipment during spray drying is small, and the fluidity, hardness resistance The effect of providing a powder article for obtaining a powder having excellent cohesiveness was also achieved.

  Hereinafter, the best mode for carrying out the present invention will be described. However, this description is based on the purpose of specifically explaining the present invention and contributing to an accurate understanding of the contents of the invention. The description is merely an example of the present invention, and is not intended to limit the scope of the present invention by this description.

  First, in the present invention, the water-containing raw material containing the hygroscopic component refers to all liquids and solid-liquid mixtures including the hygroscopic component and water or the hygroscopic component and components other than water, molasses, maple syrup, Honey, monosaccharides, liquid sugars rich in disaccharides, apples, pears, peaches, oranges, grapefruits, lemons, limes, pumpkins, eggplants, bananas, strawberries, blueberries, plums, figs, kiwifruits, pineapples, papayas, mangos , Processed fruit products containing many monosaccharides such as mangosteen and cherries, processed fruits and vegetables containing many monosaccharides, disaccharides and polysaccharides such as strawberry, watermelon, melon, pumpkin, tomato, pepper, peppers, eggplant and corn , Cabbage, lettuce, Chinese cabbage, onion, salmon, broccoli, asparagus, spinach, Japanese mustard spinach, green pepper, purple Leafy vegetables such as herbs, processed root vegetables containing a large amount of polysaccharides such as radishes, carrots, and strawberries, processed products of potatoes rich in polysaccharides such as sweet potatoes, potatoes, and taro, polysaccharides such as soybeans, red beans, and edamame Processed legumes containing a lot of almonds, pistachios, hazelnuts, macadamia nuts, chestnuts, sesame seeds containing a lot of polysaccharides such as sesame, lactic acid bacteria beverages rich in monosaccharides and disaccharides, brown algae, red algae, Processed algae products that contain a lot of polysaccharides such as green algae, processed mushroom products that contain a lot of polysaccharides such as shiitake mushrooms, maiko, shimeji mushrooms, mushrooms, yeast extract, protein hydrolysates, livestock meat extracts such as cows, chickens, and pigs, salmon Examples include those containing a large amount of amino acids, such as seafood processed products such as sea bream, salmon, salmon, salmon, oysters, clams, scallops, shrimp, crabs, and fish sauce.

  As the powdered base material, starch, modified starch, dextrin, cyclic dextrin and other powdered base materials may be used alone or in combination. For example, oligosaccharide, CMC, methylcellulose, Arabic Although it is gum, gelatin, agar, protein, etc., it is not particularly limited to these.

  A preferable result is obtained when the amount of ethanol added in the present invention is 0.1 wt% or more and less than 10 wt% of the stock solution before spray drying. If the amount of ethanol added is less than 0.1% by weight, the effect is weak, and if it exceeds 10% by weight, no improvement in the effect commensurate with the cost increase due to the addition of ethanol is observed. Moreover, even when ethanol is volatilized in the spray drying process and does not remain in the powder, the effect of improving the powder physical properties can be obtained.

  If the added amount of the powdered substrate is less than 5% by weight of the total solid content before spray drying, sufficient effects cannot be obtained, and adhesion to the spray drying production equipment is not reduced, but if it exceeds 5% by weight, it is sufficient. The effect is seen. Furthermore, by making it 10% by weight or more, a more stable agglomerate is formed, and a powder article excellent in fluidity and anti-caking property can be obtained. However, if it exceeds 90% by weight, the proportion of the powdered base material in the obtained powder is too high, and an adverse effect on the flavor of the product powder may appear. Moreover, by making it less than 70 weight%, the powder article excellent in fluidity | liquidity and anti-caking property can be obtained more economically.
