METHOD FOR IMPROVING DRYING OF A CONCENTRATED ACID SALMON SILAGE, DURING PREPARATION OF A PROTEIN SUPPLEMENT FOR ANIMAL FEED, PROTEIN SUPPLEMENT OBTAINED AND SYSTEM TO IMPROVE DRYING

摘要

Method for improving drying of a concentrated acid salmon silage, during preparation of a protein supplement for animal feed, from salmon silage, wherein in a continuous and sequential form includes treating the stored salmon silage through steps of cooking, separation, concentration, drying, grinding, addition of antioxidant, and packing, wherein after the concentration step, the following steps proceed:
a) incorporating in a first mixer an amount of concentrated acid salmon silage, and an amount of flour-type carrier, obtaining an homogeneous mixture;b) incorporating in a second mixer an additional amount of concentrated acid salmon silage, an amount from the first mixer, and a fraction of the load coming out of the dryer, the latter as a recycle;c) transferring the mixture formed in the second mixer to a dryer;d) recycling a fraction of the load, equivalent to the amount that can be from 30% to 60% of the output of the second mixer, fraction defined in function of the humidity at the exit of the dryer;e) passing the mixture of the dry product at the exit of the dryer to a cooler, wherein the cooling is performed from 80° C. to 25° C. for 10 to 30 minutes;f) feeding the dry and cooled down product to the steps of grinding, adding an antioxidant, and packing of the protein supplement for animal feed.;Also disclosed are the protein supplement and system to improve drying said protein feed.
