3,786,159 United States Patent Office Patented Jan. 15, 1974 2 are mixed together in a suitable mixing ratio (for example, 3,786,159 PROCESS OF MANUEFACTURING ALCOHOL 4:6), they are dissolved together to form a uniform alco CONTAIN ENG SOLD MATTER hol-aqueous solution. If a water-soluble material such as Jimichi Sato, Nagoya, and Tosiro Kurusu, Niwa-gun, gelatin, dextrin or the like having a coating-forming ability Japan, assignors to Sato Shokuhin Kogyo Kabushiki is added to and mixed with the alcohol-aqueous solution Kaisha, Komaki-shi, Japan and if the amount thereof is gradually increased, the No Drawing. Filed Dec. 13, 1971, Ser. No. 207,659 density of the water-soluble material in the alcohol-aque Claims priority, application Japan, Dec. 18, 1970, ous solution becomes gradually increased. The water solu 45/114,585 ble material such as gelatin, dextrin or the like is not int, C. A23 1/04 O soluble in alcohol but has a very large affinity with water, U.S. C. 426-302 8 Claims so that the same is dissolved in the existing water, and if the water-soluble material is added to and dissolved in ABSTRACT OF THE DISCLOSURE the water in an amount of about 1.5 or more times as the water, almost all of the existing water is combined with A solution of alcohol, water and a water-soluble prod 5 the water soluble material, whereby a homogeneous sys uct is formed, the water-soluble product being present in tem comprising the three components of alcohol, water an amount more than 70% by weight of the water and soluble material and water becomes a two-component sys more than 100% by weight of the alcohol. The solution tem comprising alcohol and water-containing water-solu is spray-dried at the lowest possible temperature to obtain ble material, that is, one component being a combined a powder product in which the water is substantially re 20 body of water and water-soluble material. If this system moved and the alcohol is contained within a coating of the is mixed and stirred, there is formed a dispersion system Water-soluble product. such as a kind of colloid solution in which the alcohol is dispersed in the combined body of water and water-solu BACKGROUND OF THE INVENTION ble material. 25 If, accordingly, this solution, which is a thick mix (a) Field of the invention ture solution, is sprayed, there are formed fine liquid drops This invention relates to a process of manufacturing in each of which the alcohol is located at the center and solid matter containing alcohol in high concentration by the combined body of water and water-soluble material means of simple technical expedients and inexpensive raw exists therearound. If such a drop is instantaneously dried, materials. 30 the water component is evaporated from the combined (b) Description of the prior art body of water and water-soluble material and at the same time the water-soluble material is solidified by dry It has been hitherto taken for granted that it is not ing and forms a coating surrounding the alcohol whereby possible to remove only water from a solution of alcohol the alcohol is prevented from being evaporated and is and water, because the alcohol is lower in boiling point 35 held within the coating. and higher in volatility in comparison with water. Thus, it becomes possible to remove only the water SUMMARY OF THE INVENTION from an alcohol-aqueous solution, and an alcohol-con taining solid product such as powder or the like can be According to this invention however, solid matter such manufactured easily and economically. It will be under as a powder or the like containing alcohol can be mass 40 stood that in this operation the relative quantity of the produced by simple technical steps and because the prod three components of alcohol, water and water-soluble uct obtained is solid, it can be widely used in foodstuffs, material, and the qualitative condition such as vis medicines, confectionery or the like. cosity, solubility or the like of the water-soluble material According to the process of this invention, a solution 45 have a natural relationship and a certain permissable is formed of a mixture of alcohol, water and a water-solu range thereof. ble material, the water soluble material being present in An important condition in the process of the inven an amount more than 70% by weight as compared to the tion, is that the total amount of the water-soluble ma water and more than an equal amount by weight as com terial component is above 70% as compared to the water pared to the alcohol, the solution is spray-dried at the least 50 and this has been confirmed by various experiments and possible temperature, and there is obtained a solid product will be explained with reference to the experimental ex in which almost all of the water is removed and the alco amples as follows. hol is covered with and held in the water-soluble material. The water-soluble material in this invention may be EXPERIMENTAL, EXAMPLE 1. gelatin or one or more modified starches which are easily 55 water-soluble such as "mizuame," i.e. starch converted In this experimental example gelatin and one powdered syrup, dextrin, gelatinized oxidized starch, ester starch, starch converted syrup (which will be called “starch con ether starch or the like or a mixture of the modified verted powder' hereafter) are used as the water-soluble starches and gelatin. component and ethyl alcohol is used as the alcohol com The alcohol component of the solution may be an alco 60 ponent. Into alcohol aqueous solutions, each of which holic beverage such as wine. If, in this case, the alcoholic has the ratio of alcohol to water as shown in the follow beverage contains a saccharide, protein, salt or the like, ing table, respective mixtures each comprising powder the amount of the water-soluble material to be added can gelatin and starch converted powder in a mixing ratio be accordingly decreased. Namely, it is sufficient if the of 1:1, are adde and dissolved while being agitated in a total amount of these materials previously contained in the 65 mixing ratio of 130%, 90%, 70%, 50% and 30% in alcoholic beverage and the water-soluble material which is relation to the amount of water. Thereafter, each of to be added exceeds 70% by weight of the water compo the solutions is heated to 70° C. within a tightly closed nent. container, without causing volatilization of the alcohol, The mechanism wherein only the water can be removed and is then spray-dried in a drying chamber at a tem while there remains the alcohol, which has a lower boiling 70 perature of 75° C. As a result thereof, there can be pro point than water, is presumed to be achieved in the process duced alcohol-containing powders as shown in the fol of the invention as follows: Namely, if alcohol and water lowing table. 3,786,159 3. 4. The gelatin used in 25 mp. (62/3%) in viscosity and like, or gelatin or a mixture thereof is most suitable, and has a 5% water content. The starch converted powder in this case the remaining alcohol ratio is high and the comprises 24% direct reducing sugar, 7.1% dextrin and product when dissolved in water is nearly tasteless and 5% water. odorless. Thus, when for example, an alcoholic beverage is used, the inherent characteristic taste thereof is not Number------------------------------ 1. 2 3 4. 5 affected.
