Onion Powder Production Line | 100–500 kg/h

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 Production Line Equipment and Technical Specifications

양파 뿌리 자르기 기계

This machine removes the top and root of each onion. It uses semi-automatic induction cutting and supports continuous feeding.

Onion Peeling Machine

The chain-type peeling machine removes dry skins using compressed air. It handles medium-to-large bulbs and keeps cloves intact.

Onion Slicing Machine

The onion ring cutting machine cuts peeled onions into even rings or slices. Slice thickness is adjustable.

Onion Drying Machine

The industrial drying room uses hot air circulation to dry onion slices evenly. Temperature and humidity are controlled automatically.

For an onion powder line with 100–500 kg/h final output, a medium-sized drying room such as the SL-4 or SL-6 model is usually selected.

Onion Grinding Machine

The powder grinder turns dried onion slices into fine powder. Fineness can be adjusted by changing the sieve.

For onion powder, the final fineness is usually 60–120 mesh.

Onion Powder Packing Machine

The packaging machine fills and seals onion powder bags automatically.

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.
