Sinking Fish Feed Production Line

 

In sinking aqua feed extrusion processing, according to characteristics of feed for aqua animals, require feed have good stability in water, such feed nutrients to the greatest extent possible be picked aqua animals. Meanwhile, the short aqua animal digestive tract, the degree of maturation feed a greater impact on their production and development. Thus, the degree of maturation of feed also identified an important factor in its quality. A characteristic aspect sinking feed is to be considered, Sinking aqua feed quality feed in the water cannot claim all the sink, And its sinking speed is strictly controlled, This density control of extruded material made high demands.

 

sinking extruded aqua feed for mulations typically contain energy, protein, fat, carbohydrates, vitamins and minerals and other raw materials used:
seed categories: sorghum, wheat, barley and so on;
bran: wheat bran, the flour, rice bran, bran, etc;
meal categories: soybean meal, peanut meal, rapeseed meal, cottonseed meal and other meal type;
animal protein ingredients: fish meal, bone meal, silkworm pupa powder, shrimp meal and other animal protein material;
natural mineral raw materials: source of phosphorus, calcium source, bentonite, zeolite powder;
Other common ingredients: alfalfa meal, distiller's grains, yeast, - starch, oils and fats;
In addition, depending on the circumstances, the production of special aqua feed also assisted with the need to rationalize the use of various additives raw materials, including: vitamins, minerals, amino acids, antibacterial drugs category, garlic, herbs, probiotics, enzymes , L- carnitine, betaine, unknown growth factor, binders, preservatives, antioxidants and other feed additives, and other feed additives such as soy lecithin, seaweed powder, sodium diacetate, astaxanthin, taurine, chitin, iodinated casein, polyphenols and other.

 

key equipment in sinking extruded aqua feed production line:

Sinking extruded aqua feed processing technology, the extruder is a very crucial part:


Extruder has a screw and a nut, having mixing and kneading functions. After the raw material into the puffing chamber, material between the screw nut squeezed, friction, shear effect, The internal pressure rising, the largest of 4Mpa, the temperature rising up to 140 degrees Celsius. A sharp rise in 3-7s time temperature and pressure, the organizational structure of the material changes, further gelatinized starch, Protein denaturation, Crude fiber damage, Salmonella bacteria kill harmful bacteria. High temperature and high pressure from the discharge of material out of the mouth, its sudden release of pressure at the moment, Water partial flash, after cooling the material was porous structure, the expanded material form of pellets, flocculent or coarse crumbs form.


FDSP production extruder has the following characteristics:

(1) High capacity, good performance, low power consumption, low noise, beautiful appearance;
(2) Smooth,operate, reliable, high degree of maturation of extruded material;
(3) DDC conditioning has good effect;
(4) Feeders variable frequency motor speed control, the speed can be adjusted freely;
(5) Mobile cutter holder, the cutter speed variable frequency motor control, can be cut into different lengths of the particles;
(6) Using a variety of extrusion die orifice shape to meet the production needs of different foods;
(7) Can a machine, both floating feed production, but also the production sinking feed, but also used in the pretreatment of feed ingredients;
(8) Density control system to facilitate the production of floating and sinking feed combination.

Sinking extruded aqua feed production line - can be customized recommendations :( one production line: 1-8 tons / hour; multiple production lines: 3-40 tons / hour or more) detailed process flow scheme:
Extruded feed processing technology generally contains the following:
Receiving the cleaning of raw materials
A finely pulverized material
A mixed feed ingredients and crushed
A mixed pulverized ultrafine
Secondary and post-mix ingredients
Mixture sifting
Add water, steam conditioning, wet extrusion pelleting
Subsequent drying, fat spraying and cooling
The final grading and packaging

 

How to select sinking extruded aqua feed production equipment ?

Select sinking extruded aqua feed production equipment, we must first understand the sinking extruded aqua feed has many features:
(1) Crushed particle size is small. Due to the short aqua animals digestive tract and related physiological characteristics, To speed up the digestion and absorption, Aqua feed particle size should be smaller than the crushing of animal feed, Such as the production of eel, prawn feed, Pulverized to a particle size of 80 mesh to 120 mesh.
(2) High protein content, low carbohydrate content. Protein content of animal feed are generally less than 20%, the protein content of most aqua feed 30% to 40%.
(3) Compact pellet feed, has high adhesion and water resistance, Shrimp feed material to the desired particle stability in water is more than 2 hours.
Production of high quality aqua feed must rely on scientific and rational process, aligning them with advanced, reliable, stable processing machinery combined.
