The invention discloses a triploid rainbow trout juvenile fish feed and application thereof. The formula of the feed comprises 300.0 g / kg of fish meal, 120.0 g / kg of krill meal, 100.0 g / kg of soybean meal, 80.0 g / kg of soybean protein concentrate, 80.0 g / kg of corn protein, 20.0 g / kg of wheat bran powder, 165.4 g / kg of wheat flour and a mixture of different proportions of fish oil and dephenolized cottonseed oil, the proportion of the dephenolized cottonseed oil replacing the fish oil in the mixture is 25%-100%, and 10.0 g / kg of premix, 0.2 g / kg of astaxanthin, 3.0 g / kg of choline chloride, 1.0 g / kg of EDTA, 0.3 g / kg of betaine and 0.1 g / kg of calcium propionate are added. The feed disclosed by the invention is applied to culture of juvenile triploid rainbow trout, and can be used for remarkably regulating fatty acid composition of a fish body, improving muscle texture and enhancing oxidation resistance and heat stress resistance of the liver on the premise of not influencing growth performance, so that dependence on fish oil is reduced, and green, efficient and sustainable development of aquaculture is promoted.

The application discloses a kind of vacuum drying device for phosphor shrimp powder processing, it is related to drying processing related technical field, including drying outer cylinder, the two shaft ends of drying outer cylinder downside are connected with support leg, and drying inner cylinder is rotatably connected in drying outer cylinder, driving motor is arranged in the support leg inside being connected to the outside of drying outer cylinder, multiple gas ring grooves are opened on the outer wall of drying inner cylinder in the application, and multiple jet mesh holes are arranged between gas ring groove and drying inner cylinder, multiple boost air cavities opened on the inner wall of lower end of gas guide ring can be intermittently communicated with the inside of drying inner cylinder by multiple jet mesh holes under the rotation of drying inner cylinder, so that hot air introduced into boost air cavity is pressurized and sprayed in the process of communication and dislocation with jet mesh hole, intermittent high-pressure hot gas injection is formed to phosphor shrimp powder, phosphor shrimp powder can be scattered to prevent caking, and heating can be more uniform by gas stirring, improve drying efficiency and drying effect.

The utility model discloses a krill cleaning sewage treatment device, and mainly relates to the field of krill cleaning sewage treatment. Comprising a treatment barrel, a water inlet pipe and a water outlet pipe are arranged on the treatment barrel, a cover plate is movably connected to the top of the treatment barrel, the water inlet pipe is arranged on the cover plate, a rotary disc is rotatably connected into the treatment barrel, a plurality of through holes are formed in the rotary disc, filter cartridges are movably connected to the through holes, a rotary knob is rotatably connected to the cover plate, and a plurality of fixing columns are arranged on the rotary disc. The rotary knob is movably connected with the fixing column in an inserted mode, a limiting plate is arranged on the cover plate, and a filtering box is arranged below the rotary disc. The krill cleaning device has the beneficial effects that the technical problem that the sewage treatment device is frequently overhauled in the later period due to the fact that impurities in krill cleaning sewage are easy to block the filtering device can be solved, and the plurality of filter cartridges are driven to rotate through the turntable, so that the filter cartridges are automatically replaced and used, the overhauling frequency caused by blockage is greatly reduced, and the working efficiency is improved. The sewage treatment convenience and efficiency are improved.
