How to operate the fish feed extruder machine?

The steps to install the fish feed extruder are as follows:

  1. After determining the location of the machine, dig the foundation on the ground. The size of the foundation should be approximately 10cm larger than the base frame (10cm more in length and width) and the height should be 40cm.
  2. After the foundation is built, fill it with concrete (in a ratio of 1:2:4) to make the foundation solid.
  3. Then, align the base of the machine with the holes in the foundation and tighten the screws on the base.
  4. Wait about 7 days for the concrete to fully solidify before you can start assembling the fish feed extruder.

These steps can ensure that the fish feed extruder is installed firmly and stably. Be sure to follow the specific instructions provided in the operating manual for installation.

The assembly steps of the expanded belt are as follows:

1) Installation of pulleys and pulleys:
a. Two people are required to install the pulley, making sure to align with the keyway. One person presses the shaft against the pulley until it is secure. Then, install the keyway and tighten the bolts to check whether the spindle is functioning properly. If the position needs to be adjusted, turn the pulley slightly. If it rotates smoothly, the adjustment is complete.
b. Adjust the position of the main unit or motor pulley to keep it on the same straight line.
c. Install the belt and adjust the pulley of the main motor to keep the belt at an appropriate tightness to avoid slippage caused by overtightening.

2) Installation and combination of electrical equipment:
a. Place the power distribution box on the rack next to the main motor.
b. The distribution box should have a three-phase input power connector and have a main motor output. Connect the distribution box according to the connection drawing of the fish feed extruder.
c. Perform a no-load test, start the main motor and reverse it, and connect the phase sequence wires together. If the main motor starts successfully, ensure that the fixing screws are tightened to eliminate the reason why further testing cannot be performed.
d. Start the cutter and debug it to reach normal status.

Follow the above steps to assemble the expanded belt to ensure correct installation. During operation, please refer to the machine’s operating manual and installation guide.

To troubleshoot the feed extruder, you can follow these steps:

  1. Check the power supply: First, make sure the power supply of the feed extruder is properly connected and the plug is firmly inserted into the socket. If there is a problem with the power supply, you can replace the power supply or repair the power supply failure.
  2. Check the switch: Check whether the switch of the feed extruder is turned on and whether the working mode is correctly selected. If the switch is not turned on or the setting is incorrect, you need to turn the switch on or adjust it to the correct working mode.

When using the heating ring, be careful to only use it when the raw materials are blocked to avoid heating the blocked materials into dust. During this process, the heating ring cannot be used because the high temperature will cause the material to block the screw.

During operation, pay attention to electrical safety and set up distribution boxes and wires reasonably to ensure safe use.

For the selection of raw materials, pay attention to the following matters (particle size ≤ 0.4mm):

  • The starch content should be between 20% and 50%.
  • Fat content does not exceed 8%.

Here are examples of two recipes:

  1. Formula 1: 34.8% flour, 15% defatted fish meal, 10% soy milk, 20% wheat bran, 20% rice bran, 0.2% salt.
  2. Formula 2: 34.8% flour, 15% defatted fish meal, 10% rapeseed residue, cotton pulp, 20% rice bran, 0.2% salt.

Please strictly follow the formula and requirements when using raw materials. The above is a restatement of relevant precautions.
