Fish food machinery production of extruded fish feed advantages

Fish food machinery production of extruded fish feed advantages

1. Easy to feed and manage

The fish food machine can produce aquatic puffed feed which can be suspended in the water surface (or water) for a long time, and it is not necessary to set up a special feeding platform when feeding, but only needs to be fixed feeding. Fish to gather the food out of the water, fish can be observed directly affect to gather the food situation, timely adjust feeding amount, and timely analysis to understand the growth development of the fish and health education, so can use aquatic expanded feed helps the student to carry on the cost management of social science, the enterprise a lot of work time is saved, and can improve their labor productivity.

2. Prevent feed waste

The aquatic puffed feed produced by the fish feed machine has good stability in water, insoluble for 2 hours (some as long as 10 hours), which can avoid the loss of nutrients in water and the feed falling into mud, and the residual bait is also easy to pick up and dry under the sun, thus reducing the waste of feed. The results show that the feed cost of extruded aquatic feed can be reduced by about 10% compared with that of powdered or hard pellet feed.

3. Reduce water pollution

Aquatic extruded feed is insoluble and does not sink in water, so it can avoid the use of feed residues in water for fermentation, reduce the oxygen consumption of organic matter in water, so it can effectively cause pollution by reducing the environmental water quality.

4. High feed utilization rate

The fish food machinery production puffed at high temperature can processing, to form a stable, starch gelatinization, fats and damage and softening fibrous tissue structure and cell wall, so as to improve the utilization rate of the nutrition ingredient and extrusion can significant decrease the seeds and the content of free gossypol in cottonseed meal, mustard glucoside of meal, castor meal of poisonous plant protein, etc., also has a good effect of detoxification. At the same time, these extruded processes also destroy harmful chemicals such as antitrypsin and anti-nutritional risk factors in soybean meal, thus effectively improving the palatability and digestibility of raw materials. Therefore, the utilization rate of Chinese aquatic extruded feed is higher than that of powder and pellet.

5. Storage length of feed

The extruded feed has low water content, high particle hardness and low crushing rate, and most microorganisms, fungi and insects are killed in the process of extruding. Therefore, the extruded feed has a longer storage period and is easy to be stored and transported.

6. Prevent disease

The feed was processed at high temperature at the instant of puffing, which could effectively kill bacteria such as Escherichia coli, Salmonella, etc. Moreover, the puffed feed had strong water absorption (oil), which was convenient for the addition of disease-prevention and treatment drugs. Thus, we can effectively prevent the impurity of feed in China from causing various digestive tract diseases.

7. Improve feed energy

It is difficult for hard pellet feed to increase the amount of oil added in China, but the extruded feed can add oil through information according to the nutritional development needs of aquatic animals in China, so that the oil can be evenly dispersed in the feed and the energy management level can be improved, so as to fully meet the growth needs of aquatic animals.

8. Adapt to multiple needs

Because the temperature and pressure of the fish food machine can be adjusted, it can not only produce floating feed (pelagic fish and frog), slow sinking feed (middle and lower layer fish) and sinking feed (shrimp and crab), but also meet some special requirements, such as low moisture feed, high fiber feed and so on.
