Method for producing EP compound feed containing oyster shells and EP compound feed produced thereby. {EP blended feed manufacturing method using oyster shells and EP blended feed by using its}

The present invention relates to a method for producing an EP compound feed containing oyster shells and an EP compound feed prepared thereby, and more particularly, to producing an EP compound feed containing calcium using discarded oyster shells and fructose It relates to a method for producing EP formulated feed and an EP formulated feed prepared through the same.

Currently, the oyster farming business is prevalent as a policy project of Gyeongsangnam-do in the clean areas of the southern coast such as Geoje, Tongyeong, and Goseong, but there is a problem that a large amount of by-products (oyster shells) are generated after oyster production. About 300,000 tons of oyster shells are recycled annually as shell fossil fertilizer, a soil improver, but most of them are not recycled and are stored on the beach, causing environmental pollution such as landscape damage and odor.

Currently, many researchers are actively conducting research on the recycling of oyster shells. However, as a method of recycling oyster shells, most of them are technologies that are recycled for the purpose of alkalizing soil, as disclosed in Korean Patent Registration No. 10-2130706. However, in the case of recycling oyster shells as fertilizer, the salt remaining in the oyster shell not only affects the soil, but also the fertilizer application method is problematic because the fertilizer is powdery.

In addition, fructose, which is discharged as a by-product from factories producing citron tea, etc., is a factor that increases the BOD value of water quality and causes water quality deterioration.

On the other hand, imported bone meal (bone meal) was used as a calcium nutrient must be added to the formulated feed, but its use was banned due to the mad cow disease incident. Accordingly, cement powder, which is mineral stone lime, is currently used as a substitute material, but in the case of mineral lime, serious problems may arise due to the problem of asbestos, which is a carcinogenic substance, and the problem of radioactivity caused by radon.

Therefore, in the present invention, the purpose of the present invention is to manufacture an EP formulated feed containing a high-purity calcium component by recycling oyster shells and fructose, which are difficult to process while being discharged as waste.
