Production Process Of Fish Feed Pellet Mill

Date: 2021-01-14
The traditional methods of aquafeed production have been far from meeting the fish farming needs. Pellets by fish feed pellet mill production is hard pellet, there is a kind of fish feed extruder, the processed fish feed pellet is soft. Today we are going to talk about the feed extruder machine.

Detailed Fish Feed Pellet Mill Production Process

In the production process, second grinding and second batching process are generally used to mix, and then through extrusion → drying → external spraying → cooling → crumbling → screening to complete the processing of aquatic extruded feed production.

Cleaning And Primary Coarse Grinding

After the material passes through the feeding pit, the hoist enters the cleaning equipment to remove impurities after magnetic separation treatment, and then enters the bin to be crushed. After the coarse crushing, it goes through the hoist and the distributor enters the feeding bin to participate in the first batch of ingredients. Primary coarse grinding is the pretreatment process of superfine grinding in aquafeed production process. Its main purpose is to reduce the size difference and variation range of materials.

First Batching And Mixing

The first ingredient is mainly the preparation of raw materials. This process is mainly completed by electronic batching scale.

Second Grinding Batching And Mixing

Due to low food intake, short digestive tract and poor digestion ability of aquatic animals, the particle size of aquafeed grinding is required to increase the surface area of feed. The material fineness of the second blending bin is above 60 mesh, and the density is small. There is a adding machine above the mixer, which is mainly used for the addition of additives.

 Extruding And Pelleting 

In the extrusion process, the material actually passes through a fish feed extruder machine under high temperature, high humidity and high pressure. This leads to the formation of so-called extruded feed average moisture in (25-30%). Pellets enter the dryer and water drops to 13%.

The cooled material is lifted by the hoist and then screened. Then weigh and pack.

Advantages Of Using Extruded Feed In Aquaculture

1. Improve feed utilization.
2. Reduce pollution to the environment and disease.
3. Increase the density of breeding and prolong the storage period of feed.
4. Meet the needs of animals with different feeding habits.

The above fish feed production process is the general configuration of extruded aquafeed processing, especially in the application of aquatic animals, fish and pets food.
