Common Faults and Solutions in Bowl Cutter Operation

The bowl cutter has a wide range of applications and is found in the production workshops of most food processing companies. If you need to chop ingredients like cabbage, onion, Chinese cabbage, celery, etc., into granules for making buns or dumplings – this machine can help. If you want to chop fresh meat into irregular meat granules – this machine works. If you’re producing wet pet food – this machine is suitable. If you need to mix various meats and starches into a uniform paste – again, it’s suitable. If you want to make mashed potatoes, yam mash, or taro paste – it's the right tool. If you're making red bean paste or mung bean cakes – it still works.

So, what materials do you need to chop or emulsify? Let us know!

Today’s article mainly aims to outline the common faults that can occur during the use of the bowl cutter and how to avoid or solve them. We hope this information will be helpful.

1. Knife Shaft Bearing Section

The core of the bowl cutter lies in the sealing of the knife shaft. Many users find that the bearing tends to take in water during operation. The signs are: loud noise and heating. The root cause is poor sealing of the knife shaft. After prolonged use, gaps increase, allowing water to enter the bearing.

How to avoid this issue:
1. Proper sealing and waterproof design of the knife shaft.
2. Use high-quality bearings, oil seals, and O-rings.

2. Bottom Pot Bearing

Most bottom pot bearing failures are due to water ingress. After using the machine, especially during cleaning, avoid spraying the bottom of the pot directly with high-pressure water. This can cause water to enter the bearing.

If a fault occurs: you’ll hear loud noise from that section.

Prevention tips:
1. Ensure excellent sealing and waterproofing.
2. Use high-quality bearings to ensure stability.

3. Material Leakage

After long-term use, the pot cover gasket wears down, causing leakage.

Solution: If you don’t want to adjust the rear support bracket, simply replace the pot cover gasket with a new one.

4. Inverter Panel Malfunction

If the inverter panel malfunctions, our bowl cutters (all models) do not need to stop running – the machine will still operate, although the rotation speed won’t be displayed.

We do not recommend using the rotary knob on the inverter panel for speed control. Instead, our machines are equipped with a separate speed control switch.

However, if your machine lacks a separate control switch, then the inverter panel must be replaced to start and operate the machine.
Main cause of inverter panel failure: water entering the panel during cleaning.

5. Damage to the Bowl Cutter Blades

The blades are consumable parts. Normally, they do not get damaged when cutting standard materials. However, if there are ice chunks or if the materials are too hard, the blade may chip and become unusable.

Important tip: When sharpening the blade, be careful not to damage the cutting edge. If the gap between the blade and the cutting bowl becomes too large, the cutting and emulsifying performance will deteriorate.

6. Discharge Device Not Rotating

Check the sensor switch and the discharge motor.
- The sensor switch may wear out and needs to be replaced periodically.
- If the discharge motor is damaged, note that this section requires both waterproofing and heat dissipation.

Careful usage can greatly extend the machine's life and reduce failure rates.

7. Bowl Cutter Pot Not Rotating

In most cases, this is caused by a faulty sensor switch. If damaged, replace it promptly.

Tip: Keep one or two spare sensor switches on hand to avoid production delays.

8. Material Throwing from the Left Side of the Machine

The cause is simple: the baffle plate was not installed. Even small details matter.

9. Material Leakage from the Back of the Machine

This is due to the lack of a baffle on the knife shaft. Most manufacturers don’t include it – either to save money or due to a lack of innovation.

As a result, some companies produce the same machine for ten years without any updates – the machine in year ten is the same as the one from year one, with no upgrades or innovation.
