Fish food production equipment,fish feed pellet

Most of the fish food sold on the market is produced through batch processing of fish food production equipment, which usually goes through multiple processes such as crushing, batching, mixing and processing, pelletizing and drying. The main machines and equipment for the production of fish food are.

1、Crushing machine: the raw materials for the production of fish food will be crushed machine.

2、Mixing machine: the crushed fish food raw materials will be added a certain proportion of water, additives, mixed evenly. 

3、 loading machine: the mixing of raw materials will be transported to the feed hopper of the twin-screw extruder.

Come to see the fish pellet making machine in Lima.

4、 twin-screw feed puffing machine: mixed raw materials in a high-temperature, high-pressure environment and twin-screw extrusion, extrusion through the feed mold, adjusted to the same size and length of feed particles.

5、Conveyor: the produced fish feed pellets are transported to the multi-layer drying equipment.

6、Multi-layer dryer: general oven, including electric oven, fuel oven, gas oven and steam oven, which can adjust the temperature by itself, used to dry the feed pellets to safe water content and increase the shelf life.

7、Spraying and seasoning line: including oil spraying machine and seasoning cylinder for spraying oil and food attractant, etc., mainly spraying oil on the surface of feed and removing burrs and burrs on the surface of fish feed pellets to make the surface of feed pellets smoother.

8、Cooling conveyor: reduce the temperature of the surface of drying feed pellets, promote the solidification of grease, and facilitate packaging.

9、Vibrating sieve: sieve the excess external scattering material and granule debris.

10、Packing machine: to pack and seal the made fish food.

So do you have a learning for the fish feed pellet production line?

Working principle of the mixer machine

The horizontal twin-shaft ribbon mixer is used to mix dry and powdery materials for the purpose of mixing evenly. 

During mixing, the material in the material is moved by two rotors moving in opposite directions, and performs a compound motion. The double-shaft paddle drives the material to rotate in two clockwise and counterclockwise directions along the inner wall of the machine groove. 

Pushing from the inside to both sides, the outer screw drives the material close to the cylinder wall to rotate the axis, and the axial direction is pushed from both sides to the inside, resulting in convection circulation and shear mixing in the material cylinder, completing the rapid and uniform material in a short period of time. mix.

Features:

1. U-shaped barrel structure, stable operation, uniform stirring, no dead angle, clean discharge, and wide application range.

2. The inner and outer double-layer ribbons are staggered and mixed back and forth, with fast mixing speed and high uniformity.

3. Bearings are at both ends of the mixer, the material is not easy to enter, and the maintenance rate is low.

4. The screw conveyor is convenient for feeding, the feeding port is flush with the ground, and the feeding is labor-saving and convenient.

5. The internal structure and overall design materials have passed the ISO9001 international quality system certification.

Working principle of horizontal double shaft ribbon mixer:

The machine consists of two parts: feeding and stirring.

1. Feeding part: It enters from the feeding hopper, and the material is lifted into the mixer through the screw blade and enters the mixing drum for stirring and mixing.

2. Mixing part: When the material enters the mixing drum, it performs a back-and-forth staggered movement, and the mixing effect is good.

So you can go to see the fish feed making machine for production line which can help you better learn the fish feed.

 

 

Feed formula for tilapia

 Tilapia is a tropical fish, belonging to Perciformes and Cichlidae, with the characteristics of fast growth, mixed feeding habits, few diseases and strong adaptability. The distribution of tilapia aquaculture in my country is extremely unbalanced. In southern China, due to the better climate, tilapia aquaculture, especially the aquaculture of Tilapia fingerlings, has developed rapidly, and its output accounts for about 20% of the total output of local freshwater aquaculture- 40%, becoming one of the important freshwater aquaculture species in the southern region.

Let's take a look at the feed formula of tilapia:

(1) Rice bran 45%, bean cake 35%, silkworm chrysalis powder 10%, secondary powder 8%, bone meal 1.50%, salt 0.50%, appropriate amount of "biological fattening essence", "high-efficiency health-care growth-promoting liquid" 10 catties, feed coefficient 2.1.

(2) 35% bean cake, 30% bran, 15% fish meal, 8.50% barley flour, 5% cornmeal, 5% locust leaf powder, 1% bone meal, 0.50% salt, appropriate amount of "biological fattening essence", "high-efficiency health promoting Long liquid" 10 catties, feed coefficient 2.0.

(3) 100% full-price tilapia feed, appropriate amount of "biological fattening essence", 10 catties of "high-efficiency health-care and growth-promoting liquid", 10 catties of water, sprayed on the feed and fed immediately.

And you can see the fish feed extruder machine in Lima.

Formulations suitable for marine or cage culture of tilapia:

Bran 30%, bean cake 35%, fish meal 15%, corn meal 5%, locust leaf powder 5%, barley flour 8.5%, auxin 1%, salt 0.5%.

Formulations suitable for running water or cage culture of tilapia:

Grass meal 20%, fish meal 3%, bean cake 20%, corn gluten meal 20%, rice bran 20%, bran 10%, cornmeal 5.5%, bone meal 1%, salt 0.5%.

Recipe for pond tilapia:

Dry pig manure or cow manure 50%, bran 37%, sesame residue 10%, fish meal 2%, bone meal 1%.

Make more nutritious fish feed

Fish need the correct balance of protein, carbohydrates, fats, vitamins and minerals to grow and stay healthy. This type of feed is considered complete feed.

So do you know lima, which is popular in fish feed machines.

Protein is the most important part of building a fish school. During their growth stage, omnivorous fish such as tilapia and carp require 25-35% protein in their diet, while carnivorous fish require up to 45% protein to grow at an optimal level. Generally speaking, young fish (fry and fingerlings) need a protein-rich diet more than they are in their growth stages. Proteins are the basis of structures and enzymes in all living organisms. Protein is composed of amino acids, some of which are synthesized by the body of fish, while others must be obtained from food. These are called essential amino acids. Among the ten essential amino acids, methionine and lysine are usually limiting factors, and these need to be supplemented in some vegetable basic feeds. 

Lipids are fats, and they are high-energy molecules needed by fish in their diet. Fish oil is a common ingredient in fish feed. Fish oil is rich in two special types of fats, omega-3 and omega-6, which are good for human health. The amount of these healthy lipids in farmed fish depends on the feed used.

 

Carbohydrates are composed of starch and sugar. This ingredient in the feed is a cheap ingredient that can increase the energy value of the feed. Starch and sugar also help to combine feed into pellets. However, fish cannot digest and metabolize carbohydrates well, and most of this energy is lost.

 

Vitamins and minerals are necessary for fish health and growth. Vitamins are organic molecules that are important for development and immune system function, synthesized by plants or through manufacturing. Minerals are inorganic elements. These minerals are necessary for fish to synthesize its own body composition (bone), vitamins and cell structure. Some minerals are also involved in osmotic adjustment.
