Shrimp feed pellet machine

The shrimp feed pellet machine is a ring die feed pellet making machine with triple-layer conditioners. During the processing, the materials are crushed and mixed, the starch is gelatinized, the protein is denatured, and the viscosity between the materials is enhanced under the effect of steam regulation. Finally, the materials are extruded through the ring die hole.

The video of the shrimp feed making machine

In the process of feed production, the shrimp feed pellet machine is the core equipment. We know that in feed processing, the purpose of granulation is to make pellets from finely crushed, dusty, and difficult-to-ship feed using heat, moisture, and pressure. Feed granulation with larger pellets can prevent feed components from being graded during mixing, transportation, and feeding, preserving nutrition and reducing waste.

Various capacities for shrimp feed pellet machine

In order to prolong and control the retention time of powder in the conditioner, three standard conditioners are stacked on top of the granulator, which is commonly referred to as the triple-layer conditioner pellet mill. This type of conditioner is characterized by a series connection and multiple steam injection ports. During operation, the powder passes through each conditioner in turn, extending the conditioning time of the powder. The materials can be more fully mixed with steam, which can increase the curing degree of the powder to about 40%.

Parts of the shrimp feed pellet machine

Parts Of Shrimp Feed Pellet Machine


Stainless steel feeder

Adopting advanced frequency conversion motor for feeding, with overload protection device. The variable frequency feeder can control the feeding speed so as to control the production progress.


Frequency conversion motor

The variable frequency speed regulation is to maximize the capacity of the shrimp feed pellet machine.


SKF Bearing

The bearing has the advantages of higher rated load, lower noise, greatly reducing the warranty cost, increasing the running time of the machine, etc.


Stainless steel conditioner

The core process of granulation is conditioning, which is to inject the proper amount of dry saturated steam into feed raw materials or powder to change the characteristics of powdered feed before granulation. Generally, the feed temperature after conditioning is 80-90℃, and the water content is 14-18%. The ideal conditioning time is about 30-45s.


Observe port

Open the observation port to view the effect of material modulation. In order to add or reduce saturated dry steam at any time.


Cutter adjusting handle

There are 2 cutters. By adjusting the handle, the distance between the cutter and the ring die can be changed, obtaining feed pellets of different lengths.



A direct gear transmission system is adopted, with the characteristics of stable transmission, high output, low noise, and convenient operation.


Shaft coupling

It is used to connect the two shafts together. When the machine is running, the two shafts cannot be separated.


Main Siemens motor

FAQ about the shrimp feed pellet machine


Functions of conditioner in the shrimp feed making machine

Steam conditioning is the key technology in the pellet feed processing process. The conditioning effect directly affects the internal structure and appearance quality of the pellets. Steam quality and tempering time are two important factors that affect the tempering effect. High-quality dry saturated steam can provide more heat to improve the temperature of materials and gelatinize the starch. The longer the conditioning time is, the higher the starch gelatinization degree will be. The more compact the particle structure after forming, the better the stability and the greater the hardness will be. For ordinary livestock and poultry, the tempering temperature is kept at 70-80℃ by adjusting the amount of steam added, and the tempering time is controlled at about 30 seconds by changing the length, blade angle, and speed of the conditioner. For shrimp feed pellets, triple-layer conditioners are generally used for conditioning to increase the conditioning temperature and prolong the conditioning time. It is more conducive to improving the stability of shrimp feed pellets in water, and the hardness of pellets is correspondingly increased. 

  1. The powdery materials are ripened. The ability of most animals to digest starch is very low, but they can digest cooked starch to a large extent. The conditioner can greatly increase the gelatinization degree of starch under the action of water and heat, and also promote the heat denaturation of protein in the material. The denatured protein is easy to be enzymatically hydrolyzed, thus improving the digestibility and utilization rate of pellet feed.
  2. Sterilize powder materials. Most pathogenic bacteria, such as Escherichia coli and Salmonella, are not heat-resistant. Tempering materials with a conditioner at a certain temperature can kill these bacteria and ensure the level of feed hygiene. Compared with drug disease prevention, this method of sterilizing materials with a conditioner has the advantages of low cost, no pollution, no drug residue, and side effects.
  3. The conditioning equipment can significantly improve the water resistance of the pellet feed. During the conditioning process, through the hydrothermal effect of steam, the viscous components of the material, gelatinized starch and denatured protein, can fully play the role of the binder, and can effectively bond other components around. Under the extrusion of the molding roller, the particles and particles combine more closely, so that the pellet feed becomes denser and has a smooth appearance, It is not easy to be eroded by water during feeding, which increases the stability of water.
  4. The quenching and tempering equipment can improve the granulation property of materials, increase the output, save energy consumption for granulation, and increase the life of the die and roll of the shrimp feed pellet machine. Through tempering, the material can be softened and more plastic. During the extrusion process with the die hole wall, the inner wall of the die, and the outer surface of the pressure roller, the friction force is reduced, which prevents a large amount of mechanical energy from being converted into heat energy during the granulation process, and at the same time, reduces the wear of the die and the pressure roller.

Generally, ordinary livestock and poultry feed plants can choose single shaft paddle type conditioner to ensure about 30 seconds of conditioning time, which can make the starch gelatinization degree reach about 20%, basically meeting the processing requirements of ordinary livestock and poultry feed. The aquatic feed factory shall select a three-layer conditioner to ensure that the ripening degree of the conditioned feed reaches more than 50%.
