本発明は摩砕砥石の抗菌性を改善したイオン抗菌性砥石

な障害となっている。[Problems to be solved by the prior art and the invention] IJ Fido whetstone (120'-2
20') generally has about 25 to 20% connected pores, although this varies depending on the binder. When the above-mentioned whetstone is used to grind foods, etc., starch, protein, and meat juices enter the pores connected to the whetstone, rot over time, and become a culture medium for various bacteria, becoming a major source of contamination of foods. It has become an obstacle.
これらの問題を解決する一方法として、本発明者は既に
特開昭６１−１５９３７５号公報において示したように
融砕機用砥石ポリマー複合砥石を創出し、対応して来た

繋気孔に熱硬化性等ポリマーを強制的に注入したもので
ある。As a way to solve these problems, the present inventor has already created a polymer composite grindstone for a melter as disclosed in Japanese Patent Application Laid-Open No. 159375/1983. This grindstone is made by forcibly injecting a thermosetting polymer into the interconnected pores inside the porous vitrified grindstone.
ところで、融砕機はその名称の示す如く融けているよう
に感じる程の超微粒摩砕装置という意味であって、これ
に用いる砥石の砥粒は極めて微小である。そして連繋気
孔の大きさは摩砕粒子が小さい程それに比例して微小と
なる。By the way, as the name suggests, a melter is an ultra-fine grinder that grinds particles so fine that it feels like they are being melted, and the abrasive grains of the grindstone used in this machine are extremely small. The smaller the ground particles are, the smaller the interconnected pores become in proportion to the size.
従って上記砥石ポリマー複合体の製造に於けるポリマー
の強制圧入方法においては、砥粒が微細化すればするほ
ど、ポリマーの粘性のため連繋気孔内への強制圧入は困
難であった。Therefore, in the method of forcibly injecting a polymer in the production of the above-mentioned abrasive polymer composite, the finer the abrasive grains, the more difficult it is to forcibly inject the polymer into the interconnected pores due to the viscosity of the polymer.
本発明は上記に鑑みてなされたもので、連繋気孔を有す

ことを特徴とするイオン抗菌性砥石を提供するものであ
る。The present invention has been made in view of the above, and provides an ionic antibacterial grindstone characterized in that an antibacterial metal is attached to the surface of the abrasive grains in the pores of the grindstone having interconnected pores.

属を付着せしめたことを特徴とするものである。Furthermore, in the manufacturing method of the present invention, an aqueous solution containing antibacterial metal ions is impregnated into a grinding wheel having interconnected pores, and then heated, whereby an antibacterial metal is attached to the surface of the abrasive grains within the interconnected pores. This is a characteristic feature.

銀、銅又は亜鉛等がある。By attaching an antibacterial metal to the surface of the abrasive grains in the interconnected pores in this manner, it has the effect of suppressing the propagation of various bacteria even if ground food particles enter the abrasive grains. Examples of the antibacterial metal include silver, copper, and zinc.
そして本発明法においては、抗菌性金属の原料である金
属イオンを気孔内に効率よく供給するために、粘度の低

ある。In the method of the present invention, an aqueous solution containing metal ions, which is a filler with low viscosity, is used to efficiently supply metal ions, which are raw materials for antibacterial metals, into the pores.
次に本発明の一実施例について説明する。 Next, one embodiment of the present invention will be described.

含浸された。Silver ions are known to have excellent antibacterial properties. Therefore, a silver nitrate solution was selected and impregnated into the interconnected pores of a fine vitrified grindstone. Since the silver nitrate solution has extremely low viscosity, it was easily impregnated into the fine interconnected pores in the grinding wheel.
そして先ず上記硝酸銀溶液の含浸したビトリファイド砥
石を約１１０℃で熱風乾燥した。この加熱によって硝酸
銀は、次式の反応により、無色の板状無水塩となって析
出する。First, the vitrified grindstone impregnated with the silver nitrate solution was dried with hot air at about 110°C. By this heating, silver nitrate becomes a colorless plate-like anhydrous salt and precipitates by the following reaction.

砥粒表面に安定着床してＮＯ３は消滅する。3 A g + 4 HN 03 →3AgNOi +NO+2H20 This crystal is orthorhombic and has the structure d]9435. When heated continuously, this crystal becomes a hexagonal crystal system d4. It transitions to I9 and then changes to Ag above the melting point of 212°C.
After separating into NO2 and 02, they change to Ag and NO3, and when further heated to 450° C. or higher, silver ions stably settle on the surface of the abrasive grains within the interconnected pores, and NO3 disappears.
上記操作により気孔内表面に銀を付着させることができ
る。そして付着させる銀量を増大するには、上記含浸と
加熱乾燥とを繰り返せばよい。By the above operation, silver can be attached to the inner surface of the pores. In order to increase the amount of silver deposited, the above-described impregnation and heating drying may be repeated.

的な食品加工装置を提供できる等顕著な効果がある。By stably adhering antibacterial silver ions directly into the pores of the micro-virified grinding wheel, the growth of bacteria is suppressed even when food is ground using this grinding wheel, making it possible to provide extremely hygienic food processing equipment. There are significant effects such as
