SL-312 Onion Cutting Machine vs TZ-600 Onion Shredding Machine

If you process onions in large quantities, choosing the right machine can save labor, improve cut quality, and speed up production. Shuliy Machinery offers two popular options: the SL-312 onion cutting machine and the TZ-600 onion shredding machine. Both machines handle onions well, but they are designed for different production needs.

This guide compares both machines side by side. By the end, you will know which onion cutting machine fits your business best.

What Is the SL-312 Onion Cutting Machine ?

The SL-312 is a double-head vegetable cutter built for medium-to-large commercial kitchens and food processing plants. It has two independent cutting heads. One head processes leafy vegetables such as green onions, leeks, and cabbage. The other head handles root and bulb vegetables such as onions, potatoes, and radishes.

The machine outputs 600–1,000 kg/h. Leafy vegetables can be cut from 1 mm to 60 mm. Root vegetables can be sliced from 2 mm to 10 mm, shredded from 2 mm to 10 mm, or diced at 8, 10, 12, 15, or 20 mm.

This model is ideal for central kitchens, large restaurants, and food factories that need continuous high-volume output.

What Is the TZ-600 Onion Shredding Machine ?

The TZ-600 is a compact multi-function vegetable cutter. It performs shredding, slicing, dicing, and strip cutting by swapping the blade assembly. The machine processes 300–600 kg/h of onions, potatoes, carrots, cabbage, ginger, and other root or stem vegetables.

It uses a single cutting chamber with a rotating blade disc. The protective cover has a magnetic safety switch. If the cover is opened during operation, the motor stops immediately.

SL-312 vs TZ-600: Quick Comparison

When to Choose the SL-312?

Choose the SL-312 if your daily onion volume is high and you need a machine that can run continuously. This model works well when:

• You process 500 kg or more of onions per day.
• You also need to cut leafy vegetables such as green onions or leeks.
• You run a central kitchen, large restaurant chain, or food processing plant.
• You need a machine that fits into an automated vegetable prep line.
• Your facility has 380V three-phase power.

The double-head design keeps soft and hard vegetables separate. This prevents blade damage and keeps output stable during long shifts.

When to Choose the TZ-600?

Choose the TZ-600 if you need flexibility and have limited space or budget. This model is a better fit when:

• Your daily output is below 500 kg.
• You need one machine to shred, slice, dice, and strip cut.
• You run a small food processing business or restaurant supply kitchen.
• You have limited floor space.
• Your facility only supports 220V single-phase power.

The blade change takes less than five minutes. This makes it easy to switch between different cut types during the day.

Which Machine Should You Buy?

The decision depends on your production volume, space, and product range.

• Buy the SL-312 if you want high capacity, dual-purpose cutting, and continuous operation.
• Buy the TZ-600 if you want multi-function cutting, compact size, and lower power needs.

If you mainly process onions for seasoning, frozen food, or ready-meal production, both machines can handle the job. The SL-312 does it faster. The TZ-600 does it with more cutting styles in one unit.
