The SL-312 onion cutting machine is a heavy-duty vegetable cutter built for commercial kitchens, central kitchens, and food processing plants that need fast, uniform onion slicing. This double-head vegetable cutter processes between 600 kg and 1,000 kg of raw materials per hour. It converts onions into slices, shreds, or diced pieces ready for seasoning production, ready-meal factories, restaurant prep, and frozen food processing.

Compared with single-head cutters, the SL-312 uses two independent cutting heads. One head handles leafy vegetables, while the other handles root and bulb vegetables. This split design stops hard and soft ingredients from mixing in the same cutting chamber. It protects blade life and keeps cutting quality stable. The machine is ideal for buyers looking for an industrial onion slicer that also handles other vegetables when needed.

Functional Highlights of the SL-312 Onion Cutting Machine

Dual Independent Cutting Heads

The SL-312 features two separate cutting stations. One head is designed for leafy vegetables, while the other handles root and bulb crops. Both heads can operate together or independently for flexible production.

Adjustable Leafy Vegetable Cutting (1–60 mm)

The conveyor-type cutting head processes green onions, leeks, celery, cabbage, and other leafy vegetables. The cutting length can be adjusted from 1 mm to 60 mm.

Multi-Size Root and Bulb Cutting

The hard-vegetable cutting head uses a disc system to produce uniform onion slices and shreds from 2 mm to 10 mm. It also supports dicing sizes of 8, 10, 12, 15, and 20 mm.

Independent Speed Control

Each cutting head is equipped with its own frequency converter. Operators can adjust blade speed and conveyor speed separately according to different ingredients and production requirements.

Dual Voltage Compatibility

The SL-312 supports both 220V and 380V power supplies, allowing it to adapt to different commercial kitchen and food processing environments.

Simple One-Touch Operation

The machine features a clear control panel with independent switches for each cutting head. Operators can quickly start, stop, and adjust the machine for convenient daily use.

What Are the Core Advantages of an Onion Cutter?

High hourly output

With a capacity of 600–1,000 kg/h, the SL-312 replaces several manual workers and keeps up with large-volume prep shifts.

Consistent cut quality

The machine delivers uniform slices, shreds, and dices. This helps seasoning factories, frozen food plants, and central kitchens maintain product standards.

Less manual labor and faster prep

Automated feeding and cutting reduce prep time. Kitchen staff can focus on other tasks instead of hand-cutting onions for hours.

Protects ingredient integrity

The hard-vegetable head cuts dense bulb crops cleanly without crushing. The leafy head handles soft vegetables without bruising.

Flexible single or dual-head operation

You can run one head during low-volume periods and both heads during peak hours. This saves power and extends blade life.

Food-grade stainless steel body

The 304 stainless steel construction resists corrosion and meets food safety requirements. Cleaning and maintenance are simple.

Saves space in busy kitchens

At 1,100 × 600 × 1,200 mm, the machine fits into commercial kitchen layouts without taking up excessive floor space.

Lower long-term operating cost

Durable blades, stable motors, and low maintenance needs keep daily running costs down over years of use.

How Does the Double-Head Design Work?

The SL-312 is not a standard single-purpose onion slicer. Its two cutting heads run separately. Each head has its own inlet, outlet, and speed control.

Leafy vegetable head

This side uses a conveyor belt system. It is built for long, soft vegetables such as green onions, leeks, celery, and cabbage. You can adjust the cutting length from 1 mm to 60 mm by changing the conveyor speed.

Root and bulb vegetable head

This side uses a rotating cutting disc. It is made for hard vegetables such as onions, potatoes, radishes, sweet potatoes, and taro. You can swap the blade discs to produce slices, shreds, or diced cubes.

Both heads have independent switches and frequency converters. You can run both heads at the same time or use only one when your workload is small. This saves power and gives flexible operation.

Why Is the SL-312 Ideal for Onion Processing?

Onion is a high-volume ingredient in many commercial kitchens. Cutting onions by hand causes uneven sizes, slow speed, and eye irritation. The SL-312 solves these problems with three practical advantages.

High output

At 600–1,000 kg/h, one machine can replace several workers during peak prep hours.

Uniform cutting

Whether you need onion slices, shreds, or 8 mm to 20 mm dices, the machine keeps each piece consistent. This matters for seasoning factories and frozen food producers where size control affects drying, frying, and packaging.

Suitable for bulb crops

The hard-material head is built for bulb crops. The root and bulb head handles the dense layers of onions without jamming. The dicing discs and slicing discs are easy to change, so one machine covers multiple finished product types.

Where to Use the SL-312?

The SL-312 fits any business that prepares vegetables in bulk.

Central kitchens: Process onions, potatoes, and leafy greens for school meals, airline catering, and ready-meal production.
Food processing plants: Produce sliced or diced onions for frozen vegetables, dehydrated seasonings, and sauce bases.
Large restaurants and hotpot chains: Keep prep fast and consistent during high-traffic service hours.
Canteens and factory kitchens: Reduce manual labor and speed up daily vegetable preparation.

This machine is designed for commercial use. Home kitchens are too small to use it effectively.

Key Buying Tips for a High-Capacity Onion Cutting Machine

When choosing an automatic vegetable cutter for onion processing, check four points.

Quyền lực

Commercial models usually run between 1.1 kW and 2.6 kW. The SL-312 uses 1,370W, which suits medium-to-large kitchens that process hundreds of kilograms per day.

Ask for real test data. The SL-312 is rated at 600–1,000 kg/h under normal working conditions.

Điện áp

Please confirm your local power supply before ordering. The SL-312 normally supports 220V and 380V. Customized voltage options are also available to meet the power requirements of different countries and regions.

Simple Operation and Maintenance

The SL-312 has a clear control panel with separate switches for each head. The frequency converter lets you adjust blade speed and conveyor speed. Before use, wash vegetables clean and remove stones or grit. Do not put hands near the inlet while the machine is running. Stop the power before cleaning or changing blades.

Daily cleaning is straightforward because the main body is stainless steel. Wipe down the conveyor, blades, and inlets after each shift. Lubricate moving parts as needed and check blade sharpness regularly.
