PURPOSE:To produce a solid feed in a short drying time in high efficiency, without causing deterioration of quality by thermal degradation, by adding crushed ice to a feed at a specific weight ratio to moisten the feed and forming, solidifying and drying the moistened feed. CONSTITUTION:Crushed ice is produced e.g. by finely crushing ice block produced by ice-making. The crushed ice is added to a feed at an amount of 3-30wt% to moisten the feed and the obtained mixture is formed and solidified to provide the objective solid feed. Since the feed is moistened with crushed ice, the amount of water necessary for forming is nearly half of the amount in the case of using water for moistening. Accordingly, the heat-quantity required for drying the formed feed can be remarkably reduced and the drying time can be shortened. The solid feed produced by this process exhibits improved growth, decreased occurrence of diarrhea and loose passage compared with conventional feed. |
