The global corn starch industry continues to expand as demand grows from the food, pharmaceutical, paper, textile, biodegradable plastics, and bioethanol sectors. In 2026, manufacturers are placing greater emphasis on production efficiency, energy conservation, equipment reliability, and lower maintenance costs. As processing capacity increases, every component within the wet milling process becomes increasingly important.

One of the most critical—but often overlooked—components is the Degerminator Plate, also known as the Convex Tooth Plate. Although it is classified as a wear part, its performance directly influences germ separation efficiency, starch yield, equipment stability, and overall operating costs.

Why Degerminator Plates Wear Out

Degerminator plates operate under severe working conditions.

Typical operating conditions include:

• Continuous operation 24 hours per day
• High rotational speed
• Abrasive contact with soaked corn
• Constant impact loading
• Wet processing environment

Even high-quality alloy steel gradually wears over time. As the teeth become rounded, milling efficiency decreases and energy consumption increases.

Common signs of worn plates include:

• Reduced germ separation
• Increased starch loss
• Higher motor current
• More equipment vibration
• Increased maintenance frequency

Ignoring these warning signs often leads to unnecessary production losses.

Do you know why hardness 58HRC OR 63HRC??? Due to chrome different 24% and 29%.
