る。Recently, not only desiccant agents but also insect repellents, deodorizers, and the like have been increasingly applied to foods and drinks. desiccant,
It may be possible to package insect repellents and deodorizers in separate porous materials and apply them to foods and drinks, but this has the disadvantage that the work of enclosing them in packaging containers for foods and drinks is complicated. There is.

However, in this case, there was a drawback that the desiccant came into direct contact with other insect repellents and deodorizers, which adversely affected the performance of each. for example,
If the desiccant absorbs water, deliquesces, and adheres to the deodorizer or insect repellent, the deodorizing performance and insect repellent performance may be impaired.

アセルベーションとなるように調整するのが好ましい。When an aqueous solution is dropped into an organic solvent solution using a dropping funnel or the like, droplets of the aqueous solution are dispersed in the organic solvent solution. By stirring this dispersion and making the size of the droplets fine, a suspension in which fine droplets are suspended can be produced. When preparing a suspension, it is preferable to adjust the suspension so that a thick phase of the film-forming polymeric substance surrounds the droplets, that is, coacervation occurs.

Incidentally, the term "fine droplets" as used herein refers to those having a particle size of about 1 to 1000 microns.
また、液滴の粒子径は分散液の攪拌の程度によって所望

考えられる。The resulting suspension is atomized with a sprayer to create atomized droplets. The sprayed droplets obtained from this suspension are in the form of a core of fine droplets surrounded by an organic solvent solution. Hot air is then blown onto the spray droplets. Then, the aromatic organic solvent and water in the sprayed droplets are released,
A solid is obtained. The polymer substance forms a film due to evaporation of the aromatic organic solvent, and the desiccant component remains due to evaporation of water in the aqueous solution. If the desiccant component is not regenerated into one with the desired drying properties due to the evaporation of this water,
It is preferable to further perform a treatment such as heating. One unit of the obtained solid material is a so-called microcapsule, which has a desiccant component as a core and is surrounded by a polymer membrane. The polymer membrane has countless pores. The reason for the presence of pores is that the membrane tends to become discontinuous as it dries in the dynamic state of spraying, and that the spray droplets are minute and therefore the thickness of the polymer membrane is extremely thin. Conceivable.

えると懸濁液を噴霧するのに支障が生じる場合がある。The concentration of the film-forming polymeric substance in the organic solvent solution used in the present invention is preferably about 0.5 to 20% by weight. When the concentration of the film-forming polymeric substance is less than 0.5% by weight, it tends to be difficult for the film-forming polymeric substance to completely surround the desiccant component, and when it exceeds 20% by weight, This may cause problems in spraying the suspension.

If the concentration of the desiccant component is less than 10% by weight, the amount of the desiccant component accommodated in the approximately spherical polymer membrane tends to decrease, and if it exceeds 60% by weight, the desiccant component will not be completely dissolved. A situation may arise.

If the amount of the aqueous solution is less than 5% by weight, the yield of the desiccant obtained will decrease and production efficiency will be poor, and if it exceeds 30% by weight, the desiccant component may not be completely covered with the polymer membrane. .

に付着することがない。(E) Actions and Effects of the Invention The desiccant obtained by the production method of the present invention has a desiccant component as a core, which is surrounded by a polymer membrane. Therefore, even when used together with other insect repellents, deodorizers, etc., the desiccant components do not come into direct contact with each other, so deodorizing performance etc. are unlikely to be impaired. For example, even if the desiccant component deliquesces, it will not adhere to other deodorizing agents because it is covered with a polymer membrane.
