Two Ways Food Processing Kettles Prevent Waste — And Help the World

Summary:

Why Food Processing Kettles Matter More Than Ever:

• Global food production must increase by 60% by 2050.
• One-third of food waste occurs during manufacturing.
• Kettle design can reduce waste and improve food safety compliance.

Food Waste Starts in Manufacturing

As the global population climbs toward 9.7 billion by 2050, food manufacturers face mounting pressure to increase output. But production alone isn’t the only path forward.

Reducing food waste during manufacturing is just as critical, especially considering that 32.4% of food waste originates from production issues.

Fortunately, food processing kettles can make a meaningful difference, not only by improving food safety, but also by minimizing waste at the source.

1. Reduce Batch Waste with Hemispherical Kettles

How Horizontal Blenders Can Fall Short:

• Unswept mixing gaps leave ingredients behind.
• Inefficient heating can lead to burn-on and scorching.
• Incomplete discharge wastes usable product with every batch.
  

Why Hemispherical Kettles Help Reduce Waste:

• Even, consistent heating reduces burn-on waste.
• Continuous scraper systems clear the vessel more completely.
• Optimized discharge geometry ensures more product reaches packaging.
  

Result: Less product loss per batch = more efficient production.

2. Prevent Recalls Through FSMA-Compliant Kettle Design

The Food Safety Modernization Act (FSMA), enacted in 2011, set strict new standards for food processing facilities. Recalls now apply to any food product considered a public health risk.

Key FSMA Impacts:

• Stricter hygiene and sanitation requirements.
• Mandatory recalls instead of voluntary actions.
  

Lee Industries supported this initiative from the start by engineering food-safe kettles that simplify FSMA compliance:

• Sanitary welds and seamless surfaces prevent bacteria harboring.
• Easy-to-clean designs minimize cross-contamination risk.
• Documentation support helps customers meet regulatory requirements.
  

Reducing contamination risks = fewer recalls = less food loss.

Final Takeaway: Design Impacts Global Food Goals

The drive to feed a growing planet isn’t just about scaling up, it’s also about working smarter with less waste.

Manufacturers can make measurable progress toward a more sustainable and secure food system by combining:

• Efficient hemispherical kettle designs, and
• FSMA-compliant engineering standards
