示さない。(Prior art and problems to be solved by the invention) Methods for granulating slaked lime have been studied for a long time, including shrinkage granulation method (Granulation Handbook, Japan Powder Engineering Society), method of granulation by adding water,
Methods of granulation by adding Steffen wastewater concentrate or alcohol fermentation concentrate are known, but the granules obtained by these methods do not show any disintegration in water even immediately after granulation.

ことを提案している。As an improvement of this technology, published patent publication No. 59-15221
No. 9 proposes extruding a screen under low pressure to produce granular slaked lime, since high-pressure granulation results in poor disintegration. On the other hand, published patent publication 1986-
In No. 81021, slaked lime is kneaded with an alcohol aqueous solution and then extruded through a perforated plate to form granules. j11
It is proposed that granulation be performed by mixing a large amount of carnoyum chloride, which is an auxiliary agent.
しかしなからこれらの技術について詳細に検討した結果

事かわかった。従って、従来の技術ては農業用の土壌中
和剤として十分満足てきる消石灰粒状物か得られている
とは言いがたい。However, as a result of a detailed study of these technologies, we found that although disintegration in water was good immediately after granulation or for several days, assimilation reactions progressed when left in high humidity conditions for about 2 to 4 days. It was found that it no longer shows disintegration in water. Therefore, it cannot be said that the conventional techniques have produced slaked lime granules that are fully satisfactory as soil neutralizers for agricultural use.
しかし、本発明の目的の一つは、農業用の土壌中和剤と

のが好ましい。As a binder for adhering the slaked lime powder, sugars such as those listed in No. 111i are used, and these sugars may be used alone or in combination of two or more. The sucrose may be mitose-containing sugar, raw sugar, cultivated white sugar, or refined sugar. Alternatively, calsodium saccharate formed by adding slaked lime or quicklime to an aqueous sucrose solution may be used. However, it is preferable to use sucrose having a polysaccharide content of 50% by weight or less.

In the present invention, in order to improve the disintegration properties of the obtained particles, it is preferable to add a water-soluble organic compound to the particles for granulation. Examples of water-soluble organic compounds include methanol, ethanol, propatool, LCrt-phthanol, ethylene glycol, propylene glycol, diethylene glycol, glycerin, polyethylene glycol, polypropylene glycol, polyethylene oxide, etc. Preferably, ethylene glycol, propylene glycol, diethylene glycol, These are polyethylene glycol and polypropylene glycol.

が徐々に低下し、顆粒状化する。(Function) Limestone is an unstable substance, and the granules that are granulated in an aqueous system and dried absorb carbon dioxide gas present in the air over time, and the carbon dioxide that has entered the granules absorbs carbon dioxide gas present in the air over time. The gas causes a carbonation reaction, and as a result, the granules solidify, losing their ability to disintegrate in water and not reducing their crushing strength, making it impossible to obtain a desirable granule. When saccharide is used as a binder as in the present invention, a complex of calcilum and sugar is formed, which gives appropriate mechanical properties to the granules and inhibits the carbonation reaction, thereby slowing down assimilation. Therefore, the granulated material has disintegrability in water for a certain period of time, and its crushing strength gradually decreases to form granules.
