Problem Trouble And Solutions Of Floating Fish Feed Machine

Trouble Problem Of Fish Feed Maker

Your floating fish feed machine will come out several issues after it functioned a very long time, or due to your wrong operation, your fish feed equipment has actually taken place problems or otherwise working well also quit working.

Typical problems are reduced manufacturing output, too expensive puffing or not adequate puffing, and poor pellet creating, against these difficulty issues, especially on bad pellet developing problem, several of our clients met this sort of problem, some due to basic materials formula, some because of incorrect operation, as well as in below we will provide some troubleshooting and also solutions for you.

Fixing Of Fish Feed Equipment

Solutions Of Low Production Result

1. The screw head is worn significantly, please transform the screw head or the whole screw

2. The bushing of the extrusion chamber is used substantially, please change the bushing in the extrusion chamber

3. If you transformed the formuation or otherwise? for sinking type pellets: starch web content percentage: ≥ 20%, for floating kind pellets: starch content portion: ≥ 10%. On top of that: Particularly for floating products, the material of pet protein must not be expensive.

The role of starch:

1). Starch has solid water absorption;

2). plastic strand pelletizer can improve the viscosity of the product

3). Dual feature of puffing and binding in the final pellets

The role of healthy protein:

1). Healthy protein has water absorption, elasticity and coagulation

2). Protein is divided right into: vegetable protein and animal healthy protein, Solutions containing vegetable healthy protein are generally less complicated to refine than those including pet protein. Due to the fact that pet protein is not as very easy to integrate with various other ingredients or mass as veggie protein or starch

4. Is the aperture area of the die appropriates or otherwise?

A= 1aperture area area= πr2, 10holes-8mm die 8mm diameter= 4mm redius.

fish feed pellet extruder = πr2, 3.14 × 16= 50.24 mm2.

10 holes × 50.24= 502.4 mm2.

Solutions Of Expensive Puffing Or Otherwise Sufficient Puffing.

1. the raw materials are puffed a lot also extremely.

1) the conditioner temperature is too expensive( for wet type maker).

2) the turning speed of the host equipment is too high.

3) too much or too much less water included the raw materials or in the conditioner.

4) the holes of the die mould is blocked.

2. The blowing degree of the material is not enough.

1) the extruder production ourput is low.

2) the conditioner temperature level is not nearly enough high.

3) the turning speed of the host maker is as well low.

4) the heating plate temperature level in the extrusion chamber is as well reduced.

5) water material is too reduced in the conditioner or in the raw product.

6) have you ever before changed the solution.

3. Poor pellet creating.

1) the raw products formula is not so good.

2) the working temperature level is too expensive or also low.

3) feeding raw materials is not balanced.

4) the cutting rate is not correct, too expensive or also low.

5) the reducing blades are put on.

6) the size of powder raw materials is too big, you can examine below the raw materials dimension requirement.

die mold aperture φ (mm) grinding fineness required.
1.095% reach to 90-100 mesh.
1.595% reach to 80 mesh.
2.095% reach to 80 mesh.
3.095% reach to 60 mesh.
4.095% reach to 60 mesh.
5.095% reach to 60 mesh.

4. The last pellets are rough surface area and various sizes.

1) some partial holes of the die mould are obstructed.


2) the finness of the raw materials is inadequate.

3) the raw products conditioning is bad.

4) the high quality of the die mould holes is poor.

5) the reducing blades are put on.

6) the water portion in the raw products is not remedy.

5. The extrusion temperature level is too reduced.

1) the heavy steam conditioning temperature is also reduced (for wet type maker).

2) The heavy steam inlet pipe of the puffing chamber is blocked or the temperature of the electrical heating tool is inadequate( for damp type machine).

3) Jacketed vapor line (trap) connected( for wet kind machine).

4) The temperature level of the electrical heating plate is as well low or the electric heating switch is not activated.

5) Raw material dampness is expensive.

6. Fragments are blocked before leaving the die hole.

1) The particle dimension of the raw material is also large about the size of the die hole.

2) The amount of water is not nearly enough to make the product circulation.

3) the screw pole is put on greatly.

4) The feeding inlet is blocked.
