Description

Technical Field

[0001] The utility model relates to the technical field of feed additive processing equipment, in particular to a spiral feeder for producing mixed feed additives. Background Art

[0002] Feed additives refer to small or trace substances added during the production, processing and use of feed. They are nutritional supplements that combine trace elements, vitamins, antioxidants, organic growth promoters and anti-disease substances required for the growth and development of livestock and poultry. Mixed feed additives are products obtained by using a screw feeder to transport one or more solid additives to the reactor and mix them evenly with other liquid additives or diluents in a certain proportion. This type of additive plays an important role in feed production and has a significant effect on improving the nutritional content of feed, improving the taste of feed, promoting the growth and development of animals and enhancing immunity.

[0003] However, when using the existing screw feeders, most of them place the materials directly in the feed hopper, let the materials slide along the inner wall of the feed hopper into the feed port of the screw feeder, and the auger in the screw conveyor transports the materials. However, the materials are easily affected by the humid environment and agglomerated in the feed hopper, and the agglomerated materials will not only cause blockage in the screw feeder, but also be transported by the screw feeder into the reactor and mixed with other additives, affecting the mixing speed of the mixed feed additive. Therefore, those skilled in the art provide a screw feeder for the production of mixed feed additives to solve the problems raised in the above background technology. Utility Model Content
