2 Advantages of wet-expansion machine in aquatic feed production 2.1 Current aquatic feed processing enterprises are facing special challenges. On the one hand, they need to provide special feed for aquaculture farmers, on the other hand, the quality and price of aquatic feed produced on the other hand. It must be competitive. The above requirements can be solved by wet expansion processing, which can not only reduce the cost of feed production, but also enable farmers to obtain considerable economic benefits from the use of expanded feed farming.
2.2 Aquatic feed processed by puffing equipment can produce a wide variety of products with the following advantages; improve the conversion rate of feed; improve the stability of feed in water; facilitate the control of feed density; good mechanical properties of finished feed; The cost formula reduces feed production costs; the feed is more hygienic.
2.2.1 It can produce a wide range of products. For aquatic feed, processed feeds such as shrimp, crab, squid, squid, squid, frogs, etc. can also produce full-fat soybeans, cat and dog feed, pet feed, and ornamental products. Animal feed and other specialty feeds.
2.2.2 Increasing the feed conversion rate Due to the high temperature transient (HTST) processing, the gelatinization degree of the starch in the feed is improved, which can reach 80-99%, which is more conducive to animals, especially aquatic animals (because of the aquatic animal intestines) Short and fine) digestion and absorption of feed.
2.2.3 Improving the stability of feed in water is an important indicator for aquafeeds, especially for slow-food animals such as shrimp and crab. Because the stability in water is not good, aquatic animals will be eaten in the future, and the feed will be decomposed into water, which wastes feed and pollutes water quality, which is not conducive to environmental protection and sustainable development of aquaculture, and the stability of expanded feed in water. Achieved; 12 hours, up to 24 hours or more, which is enough time to wait for the animals to feed, and the shrimp feed requires an average stability of 4 hours in water.
2.2.4 It is convenient to control the density of feed to produce floating feed, sinking feed and slow feed (the process parameters in slow feed processing are difficult to control), which is more conducive to the demand of feed for different aquaculture animals. Using floating feed, it allows the farmer to observe the feeding of the fish, so that the feed can be adjusted and the feed can be saved.
2.2.5 The mechanical properties of the expanded feed are good and not easy to be broken. Because the finished feed will generate dust after any crushing or decomposition before use, it not only increases the waste of the feed, but also pollutes the water quality and the air.
2.2.6 Feed more sanitary materials After high temperature transient (HTST) processing, equivalent to pasteurization process, all harmful bacteria in the feed are killed, thus reducing the impact of feed on aquatic animals and the harmful water to the water. Pollution.
In recent years, the wet puffing machine developed for aquatic feed has gradually developed into a variety of feeds that can be produced on the same equipment due to different design recipes, with only minor changes. Wet puffing equipment has become a tool for the production of aquatic feeds due to its wide range of uses. With the application of computer technology in the control of wet puffing machines, the control of wet puffing machines will become easier and easier, which will greatly expand the left-neck wet method. The application of the machine in the production of aquatic feed.
