Floating Fish Feed Making Machine

Floating Fish Feed Making Machine

Introduction of floating fish feed making machine:

It is a full-automatic and food grade processing fish food-making line. You can make any shape of pet food according to different market requirements. In order to increase the protein and other nutrients for our pet, the Automatic dry dog pet food machine/processing line uses meat powder, grains, beans, and vegetables as raw materials to produce pet food with a new shape, unique taste to let them live healthier.

The raw material of floating fish feed making machine:

Rice flour, cornflour, wheat flour, low temperature soya flakes meal, rice bran, wheat bran, fish powder, bone powder, etc.

The working processing of Floating fish feed making machine:

mixer→screw conveyor→twin screw extruder→air conveyor→dryer→hoister→flavoring drum and oil sprayer→cooling machine→packing machine

Products of Floating Fish Feed Making Machine:

Different shapes are made by adjusting the dies from the extruder

1.0mm,2.0mm,2.5mm,3.0mm,3.5mm,4.0mm,4.5mm...10.0mm depend on fish food dies size.

You can use this fish food-making machine to produce different size pellets by change the extruder dies easily.

The capacity for floating fish feed making machine is 120-2000kg/h for choosing:

How do the floating fish feed-making machines work?

A double-screw fish feed extruder is mainly driven by a pair of parallel screws engaging with each other to push the material, of which the screw is divided into three parts: feeding section, melting section, and uniform section. In the conveying section, the material enters the barrel from the hopper. Along with the rotation of the screw, the raw material move along the direction of the screw groove then is gradually compressed. When entering the melting section, because of the change of screw structure, pressure lifting, and the external heating from the barrel, the material in the twin-screw is strongly stirred, mixed, and cut by the screw and barrel, thus the material temperature rises and the material begins to melt until all the melting is completed.

Due to the space of the screw groove is further smaller, the material is further heated and boosted to produce a series of complex biochemical reactions, such as starch gelatinization, fat, and protein denaturation. When reaching the uniform section, the material from the extruded chamber is evenly distributed on the plate through a flow distribution plate. At this time, the pressure is usually 3-6Mpa(depending on the requirement of the extrusion), and the temperature can reach 150-200degree.

Because such high pressure in the closed sleeve exceeds the saturated vapor pressure at the extrusion temperature so that the moisture will not evaporate quickly. When the material is extruded instantaneously from the mold hole in a certain shape, the pressure begins to release rapidly, and the free water content evaporates quickly. The moisture dissipates rapidly from the material, thus the feed can cool to about 80 degrees quickly, and the feed is solidified and shaped with keeping its shape after expansion.

Features of floating fish feed making machine:

1. The main motor is frequency conversion control, which is energy-saving and easy to operate.

2. This machine is a frequency-converting speed-adjusting feeder, so the feeding is even.

3. The main gearbox is equipped with gear oil pump cooling, lubrication system, twin-screw extrusion pumping mechanism, and double-shaft extended differential modulator so that the maturity of the material is sufficient, and the degree of gelatinization of the material is over 98%.

4. Wide variety of raw materials, feed formula can contain more than 12% oil and fat. The screw has excellent self-cleaning fuction.

5. There is no need to clean the machine boring and screw when restarting or changing the variety of materials. The host adopts frequency conversion speed control to adapt to different kinds of raw materials, and the cutting cutter frequency conversion speed control to adjust the length of the material.

6. The screw sleeves are made of special materials and special processes, which are resistant to wear and high pressure.

7. The feed is sterilized at high temperature and pressure during the processing to ensure the hygiene and safety of the feed product.

8. The cylindrical hole diameter d = 1mm-10mm of the discharge die, and other special shapes die holes (can be made according to customer requirements).

9. It is suitable for processing aquaculture extruded material (floating and sinking) with water stability of more than 24 hours.

10. It is also suitable for processing ornamental fish feed, punching feed, suckling pig feed, young animals, livestock and poultry puffing materials, and high-quality puffing food.
