Due to the high production yield and low cost, fish feed manufacturing machinery is becoming more and more popular in aquaculture feed processing industry. Fish feed pellets can be divided into hard feed pellets, soft feed pellets and extruded feed. The diameter of feed pellets range from 0.5mm to 10mm. And the selection of feed size depends on what kind of aquatic animal to feed. So before searching for a fish feed manufacturing machine, you must decide what size of feed pellets you need.

Choose the Most Appropriate Size and Type of Fish Feed Pellets

Feeding big fish with small pellets is not economical. Meanwhile, feeding the young fish or shrimp with big pellets will cause swallow problem. For example, when feeding adult grass carp, 8mm feed pellets are suggested.

In addition to pellet size, we should also pay attention to the feed pellet type. There are hard feed pellets, soft feed pellets and extruded feed pellets. The first two belong to sinking fish feed, while third one belongs to floating fish feed. Once in water, the hard and soft feed pellets sinks in very short time, which is suitable for feeding the fish living in the bottom of the pond, while the extruded feed can be made floating or slow sinking.

Choose the wrong size or type of feed not only increase the feed waste, affect the fish health, but also can cause water pollution. Therefore, it is very important to choose the right fish feed manufacturing machine for making the most appropriate size and type of fish feed.

Extruded Feed Pellets

Expanded or extruded feed pellets are produced under high temperature (130~150℃) and high pressure (40 ~ 60 atmospheric pressure), help killing salmonella and escherichia coli and prevent fish diseases. The extruded feed are cooked and starch was gelatinized, making it easy for fish to digest and absorb. Recently, one a complete set of floating fish feed pellet machine was shipped to our American Agent. Some people worry that the high temperature will damage the protein inside the feed. While, we have done the crude protein content test on the extruded compounded fish feed. 

The Formula is:
Fish meal 15%, soy flour 20%, barley flour 15%, corn flour 10%, locust tree leaves 4%, bran 35%, and growth hormone 1%.

The crude protein content in the raw material measured before extruding was 25.9% and it was 27.17% after extruding. The actual effect of feed farming also proves that expanding / extruding does not destroy the crude protein in the feed.

First of all, enterprises should choose a production line that suits them according to their actual needs. The production capacity of the production line should match the actual needs of the enterprise. If the production capacity of the production line is too small and cannot meet the needs of the enterprise, it will waste resources; if the production capacity is too large and exceeds the needs of the enterprise, it will increase the investment cost of the enterprise.

Poultry feed production line includes the following equipment:

Raw material warehouse

Before pelleting, feed raw materials are stored here to facilitate the subsequent pelleting process, which is an indispensable part of feed pellet production.

Bucket elevator

Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction member to vertically lift materials.

Bulk grain received from farms often includes grain by-products and impurities such as straw, stones, metal, paper, small animal carcasses and fines. This section remove these impurities through magnets, screeners, and dust collectors to ensure that the stored grain is of good quality and to protect the machinery.

Raw material automatic distribution and weighing system

Working principle of automatic weighing and batching system: After the system is started, the control unit sends instructions to the feeding unit according to the preset mixing formula, and each feeding device transports the powder in the storage bin to the metering unit at the corresponding speed and flow rate.

Mixing system

Mixing is a key link in the production of compound feed. Components with unique properties are blended together to formulate rations under the action of external forces to meet the nutritional needs of animals and add value to the blended product.

Pelletizing system

The feed pelleting system converts the feed paste into shaped large pellets. Feed granulation is accomplished through a mechanical process using a combination of moisture, heat and pressure. Ring die feed pellet machine will used in this section.

Cooling system

During feed pelleting, cooling of the feed pellets is essential. When leaving the pellet mill, the feed pellets are very hot, soft and rich in moisture, the cooling process cools them down to 3°C-5°C slightly above room temperature and reduces their moisture content to a safe standard (≤12.5%), For easy transportation and storage.

Screen system

The central control system can intelligently control the system, intuitively see the data, control each part through the screen, and also monitor each part well.

Packaging system

The device mainly consists of three parts: automatic weighing and packaging machine, conveying device and sewing device. It is mainly suitable for quantitative packaging of granular and granular powder mixed materials.

Modern automated feed processing production lines not only have high production capacity and high stability, but also have intelligent features. Intelligent production lines can automatically control and monitor the entire production process, and provide timely feedback on production conditions, so that the production process can be adjusted in a timely manner to improve production efficiency and product quality. Therefore, when choosing an automated feed processing production line, companies should choose equipment with intelligent features, which can better meet the production needs of the company.
