By the way, it is preferable that tablets formed by compression molding powders have a hard texture with a crunchy texture when chewed with low moisture, but it is easy to absorb moisture with the passage of time during storage. There will be no soft texture. On the other hand, if a sugar coating is formed on a tablet, moisture absorption of the tablet from the outside can be reduced by the sugar coating layer. However, if a solution for coating the sugar-coating layer is supplied to the tablet to form a sugar coating on the tablet, the solution for coating the sugar-coating layer will soak into the tablet before the sugar coating layer is formed, resulting in a soft texture that does not chew. End up.

Accordingly, an object of the present invention is to provide a sugar-coated tablet having a hard texture with a crunchy texture when formed by forming a sugar coating layer on the tablet to reduce moisture absorption during storage and chewing at a low moisture content, and a method for producing the same. There is.

When forming the sugar coating layer on the tablet, the present inventors formed a shellac layer covering the whole oil and fat layer after forming the oil and fat layer covering the whole tablet, and then the sugar coating layer so as to cover the whole shellac layer. Obtaining the knowledge that the sugar coating layer can be formed while preventing the sugar coating layer from penetrating into the tablet by supplying the coating solution and drying to form the sugar coating layer, thereby completing the present invention. It came to.

The present invention includes the following inventions. (1) After supplying an oil-and-fat-containing liquid to the tablet to form an oil-and-fat layer that covers the entire tablet, the shellac-containing liquid is supplied and dried to form a shellac layer that covers the entire oil-and-fat layer, and then coated with a sugar coating layer A sugar-coated tablet is produced by supplying a solution for drying and forming a sugar-coated layer covering the whole shellac layer. (2) A sugar-coated tablet, wherein an oil / fat layer covering the whole tablet is formed, a shellac layer covering the whole oil / fat layer is formed, and a sugar-coating layer covering the whole shellac layer is formed.

The tablet that is the subject of the present invention is a product obtained by compression-molding a granular material, and even if it is manufactured by directly compressing the raw material powder, the raw material powder is once made into a predetermined shape, for example, a granular shape. The granules may be produced by tableting. Such a tablet can be manufactured using a conventionally known tableting machine.

The shape of the tablet is arbitrary, and examples thereof include a spherical body, an ellipsoid, and a cylindrical body, but it is preferable that the tablet is curved, rounded, and has no angular portion. The present invention is preferably applied to a tablet having a water retention ratio of 3% by weight or more when left for 18 hours at a temperature of 40 ° C. and a relative humidity of 90%.

This invention includes the manufacturing method of the sugar-coated tablet which forms a sugar-coating layer, preventing the solution for sugar-coating layer coating | penetration to such a tablet. In this manufacturing method, before supplying the sugar coating layer coating solution to the tablet, an oil-and-fat-containing liquid is supplied so as to cover the entire tablet to form an oil-and-fat layer that covers the entire tablet, and then the shellac-containing liquid is added to the fat and oil. It is important that the shellac layer be formed by supplying and drying over the entire layer.

That is, by forming an oil and fat layer covering the entire tablet, it is possible to prevent the solution for coating the sugar coating layer from penetrating into the tablet. Moreover, by forming a shellac layer covering the entire oil and fat layer, a sugar coating layer having a smooth surface can be formed.

On the other hand, when the oil / fat layer covering the entire tablet is not formed, it is impossible to prevent the solution for coating the sugar coating layer from penetrating into the tablet. In addition, when the shellac layer covering the oil / fat layer is not formed, the oil / fat layer repels the solution for coating the sugar-coating layer, so that a sugar coating layer having a smooth surface cannot be formed.

Various oils and fats for forming the oil and fat layer in the present invention can be used regardless of natural or synthetic. Specific examples include carbana wax, beeswax, rapeseed hydrogenated oil, palm oil, olive oil, lard, het and the like, with carbana wax and beeswax being preferred. The fats and oils can be used as solid fats or liquid fats and oils at room temperature.

In the present invention, these fats and oils can be dissolved in a solvent and used as a fat and oil-containing liquid. The solvent in this case is arbitrary as long as it can dissolve fats and oils, and specifically ethanol can be exemplified. Also, even if it is not dissolved in a solvent, if it is a solid fat at room temperature, it will be heated to a liquid fat, and if it is a liquid fat at room temperature, it will not be heated. Can be used as it is as a fat-containing liquid without dissolving it in a solvent. In addition, components other than fats and oils and a solvent may be contained in the fat-containing liquid. In such a fat-containing liquid, the fat layer after drying is 0.1 to 5.0 parts by weight, more preferably 0.3 to 3.0 parts by weight, and still more preferably 0.5 to 100 parts by weight of the tablet. It is good to supply so that it may become a ratio of -3.0 mass part.

Next, the shellac for forming the shellac layer in the present invention is a resin derived from the scale insects recognized as an existing additive. Since shellac has a high affinity for both oil and fat and sugar coating layer coating solution, after the shellac layer covering the entire oil and fat layer is formed, the sugar coating layer coating solution is supplied and dried, so that the surface is smooth. A sugar coating layer can be formed.

In the present invention, shellac can be dissolved or dispersed in a solvent such as ethanol and used as a shellac-containing liquid. The shellac-containing liquid may contain components other than fats and oils and solvents, but the shellac composition ratio in the composition excluding the solvent is preferably 50% by mass or more. Such a shellac-containing liquid has a shellac layer after drying of 0.1 to 5.0 parts by weight, more preferably 0.3 to 3.0 parts by weight, and still more preferably 0.5 to 100 parts by weight of the tablet. It is good to supply so that it may become a ratio of -3.0 mass part.

In the present invention, the sugar coating layer coating solution refers to a solution made of so-called sugar coating honey for forming a sugar coating layer. This solution has functions such as common sugars such as sucrose, glucose, maltose and trehalose, sugar alcohols such as maltitol and paratinite, pullulan, gum arabic, acid-treated starch, gelatin, flavor, pigment, vitamin C, etc. It can be prepared by heating and mixing a sex component, water and the like in a predetermined amount.

The steps from the formation of the oil / fat layer on the tablet to the formation of the shellac layer and the formation of the sugar coating layer can be carried out in a rotating container, for example. The rotating container may be any one as long as it can rotate itself and can be filled with a sugar-coated tablet. For example, it may be included in a device for forming a sugar-coated product, generally called a sugar-coated bread or a rotary pot.

The rotating container is preferably, for example, an upper-opened bottomed container that is connected to a driving motor and is attached to a rotating driving shaft that is disposed at an angle of, for example, 10 to 60 ° with respect to a vertical line. Moreover, as sugar-coated bread which can include such a rotating container, for example, FY-TS-220 manufactured by Fuji Pharmaceutical Machinery Co., Ltd. can be used. Such a sugar-coated bread may include, for example, a sugar-coating layer coating solution supply device, such as a spray nozzle, and may further include a heating device, a cooling device, and a drying device (such as a blower).

An example in the case of using a rotating container is shown. First, a tablet is accommodated in a rotating container, and an oil / fat layer covering the entire tablet is formed by supplying the oil / fat-containing liquid to the tablet in the rotating container while drying the tablet while rotating the rotating container. Can be made. As the air volume at the time of blowing can be mentioned 3m ³ / min 30 m ³ / min. When the oil and fat layer is formed, the shellac-containing liquid is then supplied, and the shellac layer can be formed by the same operation.

After the shellac layer is formed in this manner, a sugar coating layer coating solution is supplied. Here, the sugar coating layer coating solution can be repeatedly supplied to form a sugar coating layer having an appropriate thickness covering the entire shellac layer. The composition of the molasses used repeatedly may be the same, or various compositions may be set. The thickness of the sugar-coating layer covering the whole shellac layer reduces moisture absorption during storage and gives a hard texture, so that the sugar-coating layer after drying is more preferably 10 to 200 parts by mass with respect to 100 parts by mass of the tablet. Is preferably supplied at a ratio of 20 to 150 parts by mass, more preferably 30 to 100 parts by mass.

The solution for coating the sugar-coating layer is preferably repeatedly supplied to the tablet, for example, 10 to 50 times. Here, the sugar-coating layer can be formed by drying while blowing air to the tablet in the rotating container while rotating the rotating container. The air volume at the time of blowing can be mentioned 3m ³ / min 30 m ³ / min.

The tablet of the present invention may be composed of a single sugar-coated layer, but may be composed of a plurality of sugar-coated layers. When forming a plurality of sugar coating layers on a tablet, for example, when forming a two-layer sugar coating layer, (a) after supplying sugar coating nectar, supplying powder raw material and blowing wind The first sugar coating layer (semi-hard coating layer) is formed by drying. (B) Next, after the sugar honey is supplied, it is dried by blowing air without supplying the powder raw material. Two sugar coating layers (hard coating layers) can be formed.

In the sugar coating layer finishing step, it is preferable to stop the rotation of the rotating container or to take out the tablet from the rotating container and leave it to dry. Moreover, it is preferable to perform this drying process so that the moisture content of a sugar-coating layer may be 0.1-3.0 mass%.
