A chopper is a commonly used equipment in food processing, widely used for cutting, stirring, and mixing raw materials such as meat products, vegetables, and seasonings. However, during use, operators may encounter various problems that affect the normal operation and processing efficiency of the equipment. This article will provide a detailed introduction to common problems and their solutions in the use of chopper mixers, helping users better maintain and use the equipment.
1. The device cannot start
Problem description: After pressing the start button, the chopper has no response and cannot start normally.
Possible reasons:
The power supply is not connected or the power cord is damaged.
The fuse is blown.
Motor malfunction or overheating protection device activated.
Control panel malfunction.
resolvent:
Check the power socket and power cord to ensure that the power is connected properly.
Check the fuse, if it is blown, replace it with a fuse of the same specification.
Check if the motor is overheated, wait for the motor to cool down before attempting to start.
Check the indicator lights and buttons on the control panel. If there are any malfunctions, contact a professional for repair.
2. Excessive noise during equipment operation
Problem description: The chopper produces abnormal noise during operation, which affects the working environment.
Possible reasons:
Loose or worn cutting tools.
Bearing damage or insufficient lubrication.
The equipment installation is unstable, causing resonance.
Excessive or hard materials can cause equipment to operate at overload.
resolvent:
Check if the tool is loose or worn, and tighten or replace the tool if necessary.
Check the condition of the bearings, replace them if damaged, and regularly add lubricating oil.
Check if the equipment installation is stable, adjust the anchor bolts or add shock-absorbing pads.
Control the amount of materials to avoid overloading and batch processing when necessary.
3. Uneven cutting of materials
Problem description: After being processed by the chopper, the particle size of the material is uneven, which affects the quality of the product.
Possible reasons:
Tool passivation or improper installation.
The material delivery speed is too fast or too slow.
The device speed setting is unreasonable.
The characteristics of the material itself, such as hardness and humidity, affect the cutting effect.
resolvent:
Check the sharpness of the cutting tools, sharpen or replace them regularly to ensure proper installation.
Adjust the material feeding speed to maintain uniform feeding.
Adjust the equipment speed according to the material characteristics to ensure the cutting effect.
For special materials, pre-treatment (such as freezing or softening) can be carried out in advance.
4. Equipment leakage
Problem description: During the operation of the chopper, materials leak from the gaps of the equipment.
Possible reasons:
The sealing ring is aging or damaged.
The equipment installation is not tight and there are gaps.
Excessive viscosity of the material leads to poor sealing.
resolvent:
Check the condition of the sealing ring and replace it if it is aged or damaged.
Reinstall the equipment to ensure that all components are tightly connected.
For high viscosity materials, the processing technology can be adjusted or specialized sealing materials can be used.
5. Equipment temperature is too high
Problem description: During the operation of the chopper, the surface or internal temperature of the equipment is too high.
Possible reasons:
The motor runs under overload for a long time.
Cooling system malfunction or poor heat dissipation.
The ambient temperature is too high or the ventilation is poor.
resolvent:
Avoid long-term overload operation of equipment and arrange production plans reasonably.
Check whether the cooling system (such as fans and heat sinks) is working properly, and clean or repair it if necessary.
Improve the working environment, ensure good ventilation around the equipment, and add cooling equipment if necessary.
6. Automatic shutdown of equipment
Problem description: The chopper suddenly stops automatically during operation.
Possible reasons:
The motor overheat protection device is activated.
Unstable power supply voltage or power outage.
Internal circuit failure or short circuit of the device.
resolvent:
Check the temperature of the motor and wait for it to cool down before starting.
Check the power supply voltage to ensure stable power supply.
Contact professionals to inspect the equipment circuit and troubleshoot.
7. Difficulty in cleaning equipment
Problem description: After using the chopper, residual materials are difficult to completely clean.
Possible reasons:
The material has excessive viscosity and adheres to the surface of the equipment.
Improper cleaning method resulted in incomplete disposal of residues.
The device structure is complex and difficult to clean.
resolvent:
Use warm water or specialized cleaning agents to soften residual materials.
Use the correct cleaning method, such as cleaning each disassembled component one by one.
Regularly perform deep cleaning to ensure equipment hygiene.
