double screw fish feed extruder machine

Introduction

Fish farming has emerged as a profitable business due to the increased demand for seafood products. Feeding fishes in the farm requires the right feed that incorporates all the required nutrients, which can take hours to make. The invention of the fish feed extruder machine has revolutionized the industry and transformed fish farming into a more efficient, cost-effective, and easy process. One of the most commonly used machines in fish feed extrusion processes is the double screw fish feed extruder machine. In this article, we will review the double screw fish feed extruder machine in detail, discuss its operation and advantages.

What is double screw fish feed extruder machine?

The double screw fish feed extruder machine is a food processing machine that is created to produce an extruded feed processed product for aquatic livestock. The machine has two interlocking screws that mesh and counter turn to convey the feed ingredients from the hopper to the die. These screws are responsible for mixing and heating the ingredients and enable them to come together and create a homogeneous mixture that makes the feed for fish.

The double screw fish feed extruder machine is made up of several components, including a hopper, high-speed motor, pre-conditioner, screw, cutter, gearing system, steam injector, barrel, and dies. The machine has a stainless-steel finish and complies with food-grade hygiene and safety standards. The machine is equipped with an advanced control system that allows the operator to control the temperature and speed of the screws, ensuring high-quality output and efficiency.

How does double screw fish feed extruder machine work?

The double screw fish feed extruder machine has a simple operation, which is easy to learn and understand. When the machine is turned on, the hopper is filled with the feed ingredients, and the screws inside the machine will turn to convey the ingredients into the barrel.

Pre-conditioner

Before the ingredients reach the extruder barrel, they pass through the pre-conditioner, where they are mixed with steam and water to create a conditioned mass of the feed. The pre-conditioner makes the feed softer and easier to compress through the die, creating a denser and more uniform feed.

Extruding

After the pre-conditioner, the feed ingredients will pass through the extrusion barrel, which has several chambers. The screws inside the barrel turn and counter-turn to push the feed towards the end of the barrel. The pressure generated from the screws is what enables the feed to come together and form the semi-solid product that is pushed through the die at the end of the barrel.

In the extrusion barrel, the feed is heated, and the moisture is reduced through the combination of heat, friction, and pressure. This process pasteurizes the feed, reducing the risk of contamination, and making the feed last longer without the need for preservatives.

Cutting and sizing

At the end of the extrusion barrel, the feed passes through the die, where it is shaped into the desired final product form. The cutter machine, which is attached to the extruder machine, works to cut the extruded feed into small, uniform pieces. The sizing of the final products can be customized for different fish species and age groups.

Advantages of double screw fish feed extruder machine

1. High production rate

The double screw fish feed extruder machine has a high production rate, which makes it a preferred choice for commercial fish feed manufacturers who need to meet high demand. The machine can produce several tons of fish feed in a day, which is cost-effective and saves time.

2. Versatile

The double screw fish feed extruder machine is versatile and can produce feed for different aquatic species, including catfish, tilapia, trout, and shrimp. The machine can be adjusted to produce different feed sizes, shapes, and textures, making it an ideal choice for farms that need to produce different feed types.

3. Cost-effective

The double screw fish feed extruder machine is cost-effective in the long run since it reduces the cost of feed production. The machine has a high production rate, which reduces labor costs and also produces a denser feed that requires less storage space, which saves on warehouse-related expenses.

4. Nutrient retention

The double screw fish feed extruder machine uses a high-temperature and high-pressure system, which ensures that the nutrients in the feed are retained. The process of extrusion creates a gel-like substance that traps the nutrients and prevents them from escaping, ensuring that the fish gets all the nutrients they need from the feed.

5. Hygienic

The double screw fish feed extruder machine is designed to comply with food-grade hygiene standards. The machine is made of stainless steel, which is easy to clean and does not corrode, ensuring that the feed produced is free from contaminants that can harm the fish.

6. Longer shelf life

The extrusion process, which involves pasteurizing the feed, reduces the risk of bacterial contamination, giving the feed a longer shelf life. The extruded feed has a longer storage life, which reduces the risk of spoilage, thus reducing waste.

Conclusion:

The double screw fish feed extruder machine is a preferred choice for commercial fish feed manufacturers worldwide. The machine is efficient, versatile, cost-effective, and produces high-quality feed that is nutritious and safe for fish. The extrusion process has revolutionized fish farming and transformed it into an efficient, cost-effective, and easy process, and with the double screw fish feed extruder machine, farmers can produce fish feed that meets the nutritional requirements for different fish species. With this machine, fish farmers can significantly reduce labor costs, save time, increase productivity, and produce healthier and happier fish.
