Fish Feed Machine

Why do you need use floating fish feed plant?

In order to improve the utilization, digestion and absorption rate of feed, reduce the impact of feed on water environment and improve the efficiency of aquaculture production, aquatic science and technology workers have made unremitting efforts.

By optimizing feed formula, improving feed mechanical quality and processing technology, better economic and social benefits were obtained. The building of fish feed production line is an important research achievement in feed processing. Among them, the expanded floating fish feed has been well popularized and applied because it has the special functions and functions unmatched by the sinking feed.

Puffed floating fish feed can float on the water for a long time, which is convenient for feeding and management and labor saving. Because the puffed floating fish feed can float on the water for a long time, the feeding condition of the fish can be well observed after feeding, which is convenient to adjust the feeding amount according to the feeding condition of the fish. At the same time, it can accurately understand the growth and health status according to the change of fish intake and the feeding condition of fish on the water surface.

The breeding personnel can calculate the amount of bait to be fed according to the variety, specification, quantity, water temperature and feeding rate of the cultured fish, which can not only save a lot of time, but also improve labor productivity.

The use of puffed floating fish feed can reduce the pollution to water quality. The expanded floating fish feed will not dissolve in the water for a long time. The floating time of high-quality floating fish feed can be up to about 12 hours, and it is easy to observe and control the feeding, so as to reduce or avoid the pollution of powder and residual bait to the water body, which is very beneficial to environmental protection and the growth of fish.

According to different varieties and different growth and development stages, the expanded floating fish feed produced by the fish feed production line suitable for its caliber and nutritional needs can well meet the needs of conventional aquaculture and special aquaculture for its feed, which not only facilitates the aquaculture producers, but also promotes the development of production.

Due to the processing conditions of high temperature and high pressure, the starch and fat in the feed are more conducive to digestion and absorption, destroy and soften the fiber structure and cell wall, destroy gossypol in cottonseed meal and anti trypsin and other harmful substances in soybean, so as to improve the palatability, digestion and absorption rate of the feed.

In terms of breeding methods, expanded floating fish feed has wide applicability. Floating fish feed can be used in pond fish culture, rice field fish culture, running water fish culture, cage fish culture, industrialized fish culture and large water surface intensive culture. Especially for fish culture in Shanping pond, rice field and large water surface intensive culture with low culture density, the use of floating fish feed has more advantages than other feeds.

In terms of breeding species, both freshwater fish and marine fish, in addition to a few benthic fish that are very difficult to domesticate and feed on the water surface, can feed well on floating fish feeds, such as bass, snakehead, Guanbao fish, and other famous and special varieties, as well as conventionally cultivated grass carp, carp, crucian carp and other varieties.

For the beautiful frog, bass and other varieties with special physiological functions, it is more convenient and superior to breed with floating feed.

Before designing the fish feed formula, it is must be clear of feed fish species and growth stages, in order to determine the level of protein, energy and other nutrients in the feed. Not only to meet the protein needs of fish growth, but also to make the ratio of energy and protein is moderate, too high and too low energy protein ratio is not conducive to fish growth.

When designing the formula, also consider the relationship between feed nutrient levels and weight capacity, to ensure that fish can consume adequate nutrition, but also to make it feel full.

Fish mainly protein as a source of energy, the utilization of fat and sugar is lower, so the protein requirement is higher than that of livestock. Different stages of fish growth on the demand for various nutrients are different, such as carp juvenile fish feed protein content of 41% to 43%, fish species 37% to 42%, adult fish for 28% to 32%.

Generally speaking, the price of protein feed is higher than that of energy feed. We must not be greedy for cheapness, increase the proportion of energy feed and reduce the proportion of protein feed, which will virtually increase the feed cost.

Compared with large-scale feed factories, the self proportioning feed formula is lack of scientificity and rationality. Moreover, most farmers cannot accurately grasp the quality of fish meal in raw materials, which affects the quality of self ingredients. There are also some small processing plants, which often produce feed with problems such as uneven mixing of raw materials, high feed pulverization rate and easy loss after entering water.

Therefore, building a high-quality fish feed production line is vital. Richi Machinery owns over 20 years experience. We can provide you with excellent design of fish feed production line to meet your needs.

What’s more, for the production of fish feeds, requires a high degree of paste and stability in water, at this time must strengthen the conditioning conditions. Due to the extension of the material conditioning time, so that the material and steam can be fully mixed evenly. And in the high temperature starch paste and protein denaturation, paste degree increased to enhance the bonding force of the internal part of the particles, killing a variety of harmful bacteria such as Salmonella. And the appearance of the granule is bright and clean, not easy to be eroded by water. This is not only improving the stability of the particles in the water, but also improving the palatability and digestibility of the feed pellet. Ensuring that the fish have a long feeding time. Also, this prevents water pollution.
