Description

Изобретение относитс  к рыборазведению , в частности к способам гранулированных комбикормов дл  рыб. Иавестен способ получени  гранулированных комбикормов дл  рыб, включающий увлажнение смеси порошкообразных компонентов с последующим смешиванием их, гранулированием и сушкой fl. Недостатком известного способа  вл етс  получение плотных, быстро тонущих и не достаточно стойких в воде (быстро размокающих) гранул (пор дка ,1-1 ,2 г/см), что приводит к значительно потере кормов при скармливании их рыбам . Цель изобретени  - снижение плотности гранул. Цель достигаетс  тем, что увлажнение смеси осуществл ют напрыскиванием водных растворов уксусной или лимонной , или сол ной кислот концентрации 1-3% из расчета 4-1О% от веса сухой смеси. Способ осуществл етс  следующим образом. Исходну1с композицию пс ошкообраз- ных компонентов увлажн ют напрыскиванием при ее перемешивании водным раствором либо уксусной, либо лимонной, либо сол ной кислот концентрации 1-3% из расчета 4-1О% от веса сухой смеси. Увлажненную смесь комбикорма гранулируют либо продавливанием через фильеры , либо в виброкип щем слое, либо окатыванием в барабанах или тарельчатых гранул торах. Гранулы, полученные из хранул торов, высушивают в токе газа1юсител . Получают таким образом гранулы плотностью, меньшей пор дка 1,О г/см-, используемые при садковом разведении рыб на теплых водах. П р и м е р 1. Комбикормова  смесь, составленна  по рецептуре, увлажн етс  при напрыскивании на нее 3% водного раствора сол ной кислоты в количестве 6% от веса исходной комбикормовой смеси и последующим напрыскива1{ии 2% водThis invention relates to fish farming, in particular, to methods for pelleted feed for fish. An iavesten method for producing granulated animal feed for fish, which involves wetting a mixture of powdered components followed by mixing, granulating and drying fl. The disadvantage of this method is to obtain dense, quickly sinking and not sufficiently resistant (quickly soaking) granules in water (on the order of 1-1, 2 g / cm), which leads to a significant loss of feed when fed to fish. The purpose of the invention is to reduce the density of the granules. The goal is achieved by moistening the mixture by spraying with aqueous solutions of acetic or citric or hydrochloric acids with a concentration of 1-3% at the rate of 4-1% by weight of the dry mixture. The method is carried out as follows. The initial PS composition of the osh components is moistened by spraying with its stirring with an aqueous solution of either acetic or citric or hydrochloric acids with a concentration of 1-3% at the rate of 4-1O% by weight of the dry mixture. The wetted mixture of feed is granulated either by pushing through dies, or in a vibratory bed, or by pelleting in drums or dish granules. The granules obtained from the storage of tori are dried in a gas flow stream. Thus, granules with a density of less than 1, O g / cm-, used in cage breeding of fish in warm waters, are obtained. EXAMPLE 1 A compound feed formula compiled according to a recipe is moistened by spraying a 3% aqueous solution of hydrochloric acid in an amount of 6% by weight of the initial compound feed mixture and subsequent spraying 1 {or 2% water.
