Abstract: Method and apparatus used in producing a feed product or premix and the products made by the method. A predetermined quantity of krill hydrolysate is added to a predetermined quantity of dry carrier with or without a predetermined quantity of liquid marine protein. The mixture is subject to evaporation and drying steps in which relatively heavier particles are separated from relatively lighter particles. The mixture may be blended, ground and subject to chemical reaction in a balance tank prior to entering a dryer. The dryer utilizes a warm air source, a tower and a cyclone to dry the mixture following its entry into the dryer. Temperature sensitive enzymes or other bioactive products may be added to the product produced from the dryer. A method for obtaining enzymes from a fresh krill extract or an autolyzed krill preparation and the product are also disclosed.

Abstract: Method and apparatus for harvesting and processing zooplankton and, in particular, for harvesting and processing euphausiids for subsequent use as a feed product for early stage juvenile or larvae feed or for a food product as an additive. The euphausiids are continuously harvested from coastal waters and dewatered. The dewatered product is passed to a heat exchanger to increase its temperature and, thence, to a digester where a desired level of enzymatic activity is obtained. The product is then held by a surge tank for subsequent transfer to a ball dryer where the product is dried at a relatively low temperature without destroying the stabilized enzymes created in the digester. The digesting step may be deleted in the event the end use of the product is for a food product.
