In onion processing, even small inefficiencies can quickly become costly. Minor losses in yield, unnecessary trimming, or inconsistent peeling may not seem significant in isolation, but over time they can have a measurable impact on productivity and profitability.
One of the most common causes of avoidable waste is inconsistent peeling. If too much outer layer is removed, usable product is lost. If too little is removed, additional manual trimming may be required further down the line. Achieving the right balance is essential to protecting yield while maintaining quality standards.
Well-designed onion peeling equipment, like the Onion Peeling Machines we manufacture at M&P Engineering, plays a key role in striking this balance. Controlled peeling action ensures that only the necessary outer layers are removed, helping to maximise usable product. Careful handling also reduces damage to the onion itself, limiting breakage and unnecessary waste.
Beyond the machine itself, setup and maintenance have a direct influence on waste levels. Regular inspection of wear parts, correct adjustment of settings and routine cleaning all contribute to reliable performance.
How well the operator knows the machine is equally important. Teams that understand how to respond to changes in onion size or skin condition can make informed adjustments rather than overcorrecting. Clear operating procedures and simple checks at the start of each shift help maintain consistency across different operators.
It is also worth reviewing data where possible. Monitoring output, reject levels and trimming requirements over time can highlight patterns and reveal opportunities for improvement. Even small percentage gains in yield can translate into significant savings over the course of a year.
Reducing waste in onion processing does not usually require major changes. Often, it is the combination of reliable equipment, correct setup and consistent working practices that delivers the greatest benefit.
M&P Engineering specialises in producing food processing machinery designed to meet the demand of the industry. Our Large Onion Peeling machine uses self-adjusting floating knives to top, tail, and peel onions of 45mm to 115mm in diameter, and ensures that the product remains in pristine condition due to the dry peeling process for onions going through the machine.
At M&P Engineering, we have over 50 years’ experience manufacturing food preparation and processing equipment, trusted by industry leaders. From our Manchester base, we supply machines to clients from all around the world.
