An onion powder production line is an integrated processing system designed to convert fresh onions into dried, ground onion powder. It handles the full workflow from raw material preparation to final packaging. A standard line processes 100–500 kg of finished onion powder per hour, depending on the machine configuration.

The complete line includes onion root cutting, peeling, slicing, drying, grinding, and packaging equipment. Each stage is matched to the required capacity. This solution is suitable for seasoning manufacturers, dehydrated food processors, spice exporters, and food ingredient suppliers who need stable commercial output.

Compared with buying separate machines, Shuliy’s integrated onion powder making machine system saves installation time, reduces material handling, and keeps each stage running at the same speed. The line uses food-grade stainless steel contact surfaces and supports voltage customization for different countries.

Complete Onion Powder Production Process

The standard onion powder processing line includes six main stages:

  • Onion root cutting — removes tops and roots.
  • Onion peeling — removes dry outer skins.
  • Onion slicing — cuts onions into thin, even slices.
  • Drying — reduces moisture for long storage.
  • Grinding — turns dried slices into fine powder.
  • Packaging — packs powder into sealed bags.
    Each stage uses

Each stage uses a dedicated machine. When connected properly, the line runs continuously from raw onion to finished package.

Onion Powder Processing Line Functions Explained

Onion root cutting

The onion root cutter removes tops and roots using semi-automatic induction cutting. It handles onions from 5 cm diameter upward and reaches 500 kg/h. Clean cuts make peeling easier in the next stage.

Onion peeling

The chain-type peeling machine uses dry pneumatic force to remove outer skins. Peeling rate reaches 95–98%. No water is used, so the material stays dry before slicing.

Onion slicing

The SL-30 onion ring cutting machine slices peeled onions into rings or flat slices. Slice thickness is adjustable from 1 mm. Four feed hole sizes (55/70/90/100 mm) handle different onion sizes.

Onion drying

The industrial drying room removes moisture using hot air circulation. Temperature and humidity are controlled automatically. For a 100–500 kg/h powder line, the SL-4 or SL-6 dryer is usually selected.

Onion grinding

The SL-B series grinder pulverizes dried onion slices into powder. Fineness ranges from 20 to 120 mesh. For commercial onion powder, 60–120 mesh is common.

Onion powder packaging

The SL-450 packing machine fills bags from 80–190 mm wide and 90–310 mm long. Back sealing protects the powder from moisture. Speed reaches 10–40 bags per minute.

How to Choose the Right Onion Powder Production Capacity?

Before buying an onion powder processing plant, consider three points:

Daily output target

A 100 kg/h line produces about 800 kg per 8-hour shift. A 500 kg/h line produces about 4,000 kg per shift.

Raw material supply

Make sure your onion supply is stable and sized correctly for the root cutter and peeler.

Energy source

Choose the drying heat source that matches your local electricity cost, fuel price, and emission rules.

Workshop space

The drying room and packing machine need the most floor space. Confirm layout before ordering.

よくある質問

What is the total power requirement for the full onion powder line?

Total power depends on the configuration. A 300 kg/h line typically requires 20–35 kW including drying, grinding, and packaging.

How long does it take to dry onion slices?

Drying time is usually 4–8 hours depending on slice thickness, initial moisture, and drying temperature.

Can the line also produce garlic powder?

Yes. Most machines in this line can also process garlic. You may need to adjust cutting blades and drying parameters.

What is the recommended onion slice thickness before drying?

2–5 mm is ideal. Thinner slices dry faster but may stick together. Thicker slices need longer drying time.

Does Shuliy provide installation and training?

Yes. We offer installation guidance, commissioning support, operator training, and a 12-month warranty.

Can the packaging machine handle different bag sizes?

The SL-450 supports bag widths of 80–190 mm and lengths of 90–310 mm. One former handles one bag width at a time.

Is the line available in 220V single-phase power?

Some machines support 220V single-phase. The root cutter and large dryer usually need 380V three-phase power.
