Feed is essential to the normal growth and development of livestock. Fish, like other domestic animals, also need supplemental feed and nutritional feed to grow and survive properly. Nutritional feed should be supplemented in aquaculture production. Therefore, they need to have a complete and balanced nutritional feed, such as protein, fat, vitamins, carbohydrates, minerals and water components. Fodder such as moss or aquatic insects can not satisfy the normal growth and survival of aquarium or aquarium.
Fish feed, also known as aquatic feed, is a commercially produced feed made from a variety of foods and is suitable for different aquatic species, including fish, crustaceans and mollusks. Fish feed is widely used in aquaculture.
Fish feed production business plan
Before you start the fish feed production business, you need to have the perfect business plan for making fish feed. First, you need to understand how the fish feed is made, now look at the details:
- You need to go through the list of licenses, permits, and registrations required to start a fish feed production business.
- The second is the land needed to start a business.
- Then there is the list of ingredients needed to make fish feed.
- Next buy the machinery to produce fish feed.
- And finally, the major part of the investment needed to start the business.
Machine For Making Fish Feed
Floating fish feed machine is the best choice for homemade fish feed and fish farms. With a floating fish feed extruder, you can use cheap local raw materials to produce high-quality feed and reduce feed costs.
Making money from fish feed production
Fish feed is a specially prepared food for fish and can be commercially produced on a small or large scale depending on the amount of business you can invest in. Fish feed is mainly in the form of pellets, which are made up of mixtures of important nutrients for fish. These particles come in various forms and sizes, depending on the type and size of the fish. In addition, the characteristics of the particles are based on the special requirements of the end user, that is, to make them sink to the bottom of the aquarium, otherwise they will float on the surface of the aquarium. The nutritional composition of the feed can be changed according to the species of fish, which is beneficial to the development of the global fish feed market in the near future.
Fish feed manufacturing process technology
Raw Material Selection
Maize (Corn), Wheat Flour, , Wheat Bran, Rapeseed Oil Cake, Soybean Oil Meal/Cake, Fish Powder, Vitamins, Salt, Mircoelements, Barley Flour, Cassava, etc.
Starch is usually an important component in aquatic feed, and the content of starch can reach 5% ~ 60%. It is suggested that the starch content of the submerged fish feed should be 10% ~ 15% and that of the floating fish feed should be no less than 20%. Carbohydrates act as adhesives, suspensions and emulsifiers in the extruded fish feed pellets. It is an important factor in determining many structures and special sensory properties of extruded products.
Crushing process can reduce the size of raw material to the desired size. For larger aquatic feed production plants, secondary crushing technology is adopted, that is, ordinary crushing first, and then fine crushing.
Mixing is one of the most important processes in aquatic feed production plant. If the physical properties of the feed ingredients are the same, mixing is very simple. But in fact, the physical properties of feed materials are diverse, and the problems of mixing and separation coexist. These physical properties include: particle size, particle shape, density or specific gravity, hygroscopicity, static charge, and viscosity.
The main purpose of the fish feed extruder is to make the fish feed granules with the required size by extruding the mixed raw materials. The production capacity of wet fish feed extruder is higher than that of dry fish feed extruder, so usually the wet fish feed extruder is suitable for large feed pellet factory.
Fish Feed Pellets Drying
In order to prevent mildew of fish feed, aquatic feed must have good anticorrosive properties. For the fish feed factory, the most economical method is to reduce the water content of the feed, this is achieved through the dryer. After heating and drying, the water content of the product is controlled below 11.5%, coupled with good sealing packaging, under normal circumstances, the feed can be stored safely for a long time.
In the production of fish or aquatic feed, edible oil and heat-sensitive components are usually sprayed with a roller sprayer. As the feed pellets fall, a vaporous liquid substance is sprayed at them, bringing the feed pellets into full contact with droplets in the air.
Fish Feed Pellets Cooling
After the fish feed particles are sprayed, they are transported to the countercurrent coolant. Countercurrent cooling machine has many advantages in the processing of fish feed pellets, such as high degree of automation, small air volume, low power consumption and small occupation area.
