With the development of the aquaculture industry, the application of aquatic feed has become more and more extensive. The feeding machine has also played a very important role in the promotion of aquatic feed, and has played a good role in expressing the effect of aquatic feed. However, due to the simple structure of the bait feeder and the low processing conditions, manufacturers of bait feeders have sprung up, and the quality of various bait feeders varies from time to time, and many of the poor quality products are sold on the market. So it greatly affects the farmers' correct choice of feeding machines. So in practical applications, how can farmers make the correct choice of feeding machines in a targeted manner?

At present, the bait feeders on the market are mainly divided into four types: 70W 90W 110W 120W, of which 90W and 110W are the majority. These two kinds of power can feed materials with a diameter of 2.5 mm, and the feeding area can reach about 100 square meters, which can feed 10-15 acres of pond fish. The 70W feeding area can reach about 70 square meters, which can be used for about 10 acres of fish ponds, and the 120W feeding area can reach about 130 square meters, which can be used for 15-20 acres of fish ponds. At present, although there are many bait feeders that meet the requirements, due to the poor manufacturing level, the bait area is often too small (biasing direction, spray angle can not reach 45 °, etc.), resulting in too small feeding area, affecting the feed Feed normally.
