Processing Quality And Fish Feed Extruder Equipment Control Key Points - China

Our company Fusmar has high-quality floating fish feed pellet machine on sale.

Fish feed extruder is an indispensable equipment to make fish feed pellets.

That’s what you should know about processing quality and fish feed extruder equipment control key points.

Control Principle Of Crushing Raw Materials Size

The pore size of the sieve should less than one-third of the pore size of the die, and the maximum pore size of the sieve should not exceed 1.2mm.

The appearance of the fish feed pellet requires that the finer the crushing particle size of the material during the fish feed extruder extrusion puffing process, the better of product appearance.

In addition, it is necessary to control the crushing fineness of the material economically and reasonably according to the breeding species and reduce unnecessary crushing costs.

Screening And Removing Impurities Of Semi-finished Powder

When the extrusion die hole is less than 2.0mm, the powder must screen to remove impurities with 18 to 24 mesh.

When the extrusion die hole is 2.0mm or more, the powder must screen to remove impurities with 12 to 16 mesh.

When the die diameter is below 2.0mm, if the proportion of raw materials containing fur and cotton shells in the formula is large, the stability of extrusion production is still poor even after screening with a 24 mesh screen.

Effective Pressure Distance Of Die Hole Structure

Designing the pressure distance parameter, when the hole diameter is less than 1.5mm, the pressure distance should be 1.2 to 1.5 times the hole diameter, and when the hole diameter is greater than 2.0mm, the pressure distance is 0.8 to 2.0 times the hole diameter.

The relationship between the pressure distance and the appearance of the product is that the die hole pressure distance is short, the product surface is porous, and the shape is spherical.

The die hole pressure distance is long, the product surface is smooth, and the shape is a cylinder.

Selection Of Drying Process Equipment

When the product specifications and shapes are various, a conveyer dryer should be selected, which has self-cleaning and hot air circulation functions.

When the product specification has a single shape and a large production batch, a multi-stage flap countercurrent dryer can be selected.

When choosing a dryer, we must consider the requirements for the moisture uniformity of the product.

The scientific and stable structure of the cloth and the discharge, and the maintenance of the integrity of the particles and the prevention of cross-contamination of the process.

After Spraying Process Equipment Selection

Before spraying the material, fine powder and larger particles should screen and remove.

Continuous drum injector can select when the fuel injection amount is less than 5%, and batch vacuum injector (single fluid nozzle) should select when the fuel injection amount is more than 5%.

In addition, it is necessary to accurately control the number of materials and liquid added according to the formula ratio to achieve uniform spraying.
