PREPARATION EXTRUDED DRY fish feed, mainly for aquarium fish, and extruded dry food for FISH, mainly for aquarium fish cooked this way

摘要

1. A method for preparing an extruded dry pet food for fish, especially for aquarium fish, comprising preparing a dry mixture based on cereal containing soy component, wheat bran and additives, loading moisturized mixture into an extruder, extruding the mixture heated to a temperature above 100 ° C, extrusion of the plasticized mixture through the die under pressure matrix, swelling of the extrudate at the die outlet of the matrix under the influence of differential pressure, the formation of the porous tow and cutting the tow into pieces by Leach in that when preparing the dry mixture based on cereal crops as soy component used bagasse soy, and as additives used flour corn flour and at least one of dried aquatic organisms from the group of: gammarus, daphnia, crank, trubochnik and fish in the following ratio, wt%: 10-15 soybean cake, wheat bran 3-5, flour, corn flour and 20-80, at least one of dried aquatic organisms of the group of - the rest, wherein prior to loading the mixture into the extruder. pre osusches vlyayut cyclic starting heated extruder external heater to a temperature of 150-180 ° C and air cooling it to a temperature of 115-130 ° C, and after the second cycle of heating and cooling the heated heater external of the extruder is stopped, whereupon loading moistened mixture to an extruder, wherein extruding the mixture to produce an internal heating raw materials to a temperature of 115-140 ° by the thermal energy released by the action of friction forces between the mixture, the extruder screw and the housing, and punching plastifits
