METHOD FOR RECYCLING APRICOT VINEGAR LIQUID AND OYSTER SHELL AS HIGHLY FUNCTIONAL RESOURCE

摘要

PROBLEM TO BE SOLVED: To recycle Japanese apricot (ume) vinegar liquid and oyster shell, which although respectively having useful substances, are serious and heavy loads on environments as they are, as highly functional resources.;SOLUTION: The ume vinegar liquid is an extract obtained by biochemical reaction of ume fruit and salt and on the other hand, the oyster shell is an organic compound enriched with structure water around Ca in which seawater mineral is accumulated while enclosing and growing oyster therein. Both are enriched with particular inherent components. The oyster shell is calcined at a high temperature in dry distillation manner to obtain a fine powder of quick lime. Both resources are separately jetted and mixed in a highly functional reaction tower having a long cylindrical shape and complete fusion reaction is induced in the environments of high temperature due to simultaneous exothermal chemical reactions; that is, hydroxylation reaction and acid-neutralization reaction. The reaction agent obtained thereby is separated into solid matter analogous to gypsum and a liquid agent. The solid matter is added to, for example, a raw material for marine base construction and used for contribution to oyster culture industry by seaweed propagation. Being mixed with special humus extract liquid, the liquid agent is aged and used as an acidic mineral for soil amendment.;COPYRIGHT: (C)2006,JPO&NCIPI
