【発明の詳細な説明】 この発明は、養殖ハマチの残餌処理方法に関する。[Detailed description of the invention] The present invention relates to a method for treating leftover feed of farmed yellowtail.

なっていた。Conventionally, farmed yellowtail is cultivated by feeding small fish, shrimp, and minced sardines into aquaculture cages, but the uneaten remains of yellowtail settle on the seabed and pollute the seawater. 10. Although this is sometimes removed because it is unsuitable for farming yellowtail, this residue mixed with seawater cannot be used again and is discarded, and there are problems with bad odors and problems with finding a place to dispose of it. , and was left with a loss of 11 people economically.

餌処理方法を提供ｔ！ｌυとするものである。This invention provides a method for treating leftover feed for farmed yellowtail that can be reused by treating the remains of these IC yellowtail baits that have settled on the seabed with oil temperature under certain reduced pressure conditions, and that makes it possible to treat the leftovers with zero effectiveness. Provided! It is assumed that lυ.

収容しｌこクツカー中に投入する。To explain in detail the embodiments of this invention, first, the raw material is the residue of yellowtail culture feed, which has a shape of a yellowtail that has been deposited on the seabed and is vacuum-absorbed with seawater. The bait residue is placed in a scooper containing oil preheated to 80 to 120°C.
油は植物油、動物油を使用し、たとえばイワシ油、ナタ
ネ油、豚の脂身からとったラード等を使用する。The oil used is vegetable oil or animal oil, such as sardine oil, rapeseed oil, or lard obtained from pork fat.

That is, approximately 10 to 2011111 for about 30 minutes after blood input.

The pressure of Ho was reduced and the oil was heated for about 3 hours.

て使用覆る。Next, the raw material is discharged from the cutter, taken out, and the oil is extracted and deoiled (using normal hexane) to reduce the water content to 6.
It is made into a powder of around 30%, and this is used again as bait for yellowtail.

状のものを再生できることになる。In the embodiments of this invention, the raw materials are heat-treated under two-step reduced pressure conditions depending on the oil temperature, so that the water-soluble protein, piratin, etc. in the bait remain in a nearly hardened state, and the water content is The residue is dehydrated deep into its structure, and the oil is sufficiently extracted in the next step to remove the oil with normal hexane to a residual oil ratio of around 8%, and it is possible to regenerate powder powder. become.
しかも、油温処理過程において、泥状の残滓物中含まれ

きる。Moreover, in the oil temperature treatment process, the water contained in the muddy residue is distilled, and the salt crystallizes and precipitates, so that the dehydrated raw materials do not contain seawater either. Therefore, when it is used again, it can be prevented from becoming highly mineralized with a salinity of 1I and 11 degrees due to seawater, and there is no problem in reusing it as bait, and it can be used satisfactorily as yellowtail bait.

The effect of being able to reuse it as bait in the optimal state C is right.
