Production of competitive feed for aquaculture

The subject of research was the techniques for the feed industry to select the main areas for improving the production of fish feed using promising competitive technologies and equipment. The research was carried out using information and analytical monitoring, as well as analysis and generalization of data obtained from open information sources. In the course of the research, the advantages of extrusion processes for the production of compound feed for aquaculture were identified and substantiated, in particular, such as sterilization; homogenization; stabilization of raw materials; increasing the digestibility of feed; reduced crumbling and less water pollution during feeding. These processes, due to their high efficiency and the possibility of using waste and secondary agricultural raw materials, can be considered as the best available technologies. The paper provides specifications of up-to-date feed extruders from foreign and domestic manufacturers. The advantages of using foreign technologies and equipment in the production of extruded fish feed at large enterprises are shown. It has been proven that mobile feed mills and mini-shops are promising for launching production directly at the farm using the available own raw materials and domestic equipment. The results of the work will contribute to the formation of an open source of information on the scientific and scientific-engineering groundwork in the field of innovative technologies and equipment for the production of feed for aquaculture. This includes providing their implementation at agricultural enterprises and the implementation of the state program of the Russian Federation titled ‘Development of the fishery industry’.

Introduction. The article considers biological resources of the Arctic, which is expedient to use in the production of fish meal for feeding farm animals. The aim of the research is to prove the usefulness of a continuously operating two-chamber line for sublimation drying of fish products using natural freezing of fish catch and a cheap source of thermal energy for drying: ethane, propane, butane (waste when cleaning natural gas and petroleum products of local enterprises), as well as microwave energy. Materials and Methods. A continuously operating two-chamber sublimation line is proposed, the chambers of which work alternately: one for the process of sublimation drying, and the other for loading and unloading processed products. The natural freezing of fish and thermal energy for the process of sublimation (drying) from the burning of waste gas are used whenever possible. When there is cheap electricity, it is advisable to use microwave energy for drying that makes it possible to shorten the drying cycle, ensure uniformity and simultaneity of drying the material up to 3–5% humidity without rearranging the trays along the height of the cart. Results. We propose the construction of a two-chamber sublimation line for large lump products and a sublimation unit based on microwave energy, which allows regulating the sublimation drying temperature within specified limits. Discussion and Conclusion. The presented design solutions of a large lump product sublimation drying line and sublimation unit using microwave energy are necessary for designing equipment based on digital technology.
