The issue of bacteria growth and infestation in process equipment used in the processing industry has become a common problem. The process equipment used primarily in the food industry for food processing usually requires much effort to wash, thereby making it difficult to keep them clean. This results in scratches on the surface of these stainless-steel materials. This small dent on the equipment can serve as a habitat for bacteria. They live here and multiply, thereby contaminating the process equipment and raw materials put into it.

Applying a thin layer of cooking oil in the stainless-steel food processing implements has been found to deter bacterial growth. This discovery is of utmost importance to the confectionery industry. It was discovered by Professor Ben Hatton of the University of Toronto’s Department of Materials Science & Engineering and his research team. This simple solution led to a 1000x reduction in the bacterial levels inside the process equipment used in the test.

The cooking oil does this by filling in microscopic cracks and cracks on the surface of the process equipment that might otherwise be contaminated by bacteria and leftover food. “Coating a stainless steel surface with a cooking oil every day proved to be remarkably effective in repelling bacteria,” said Professor Ben Hatton. “The oil fills the cracks, creates a hydrophobic layer and acts as a barrier against surface contamination,” Hatton said the whole research began when a Canadian seed company, approached and asked how to avoid cross-contamination in its seed process equipment.

“So they were describing this problem of contamination. The bacteria adhere to the stainless steel surface that was used to mix,” he said. “They always had to clean it and make sure there was no more bacterial contamination.”

Meanwhile, Hatton had previously worked on making slippery and non-sticky surfaces at Harvard University, trapping liquid lubricant on a solid surface. Though he had never specifically focused on doing this for food processing surfaces. What Hatton had done was to find the lubricating fluid that was safe for food processing for the sake of the process equipment used in the confectionery industry.

They needed a fluid that would not be toxic, and that won’t change the chemical composition of the food been processed, so the regular cooking oil was adopted. This discovery is beneficial to confectionery manufacturers who use the process equipment, as they can now use the regular cooking oil to reduce and prevent bacteria during food processing. Another benefit of this discovery is that the lubricating fluid -cooking oil- is cheap and cost-efficient.

Hatton said that so far, this research is only in the early stages and he hopes to partner with members of the cooking oil industry to investigate his hypothesis and see if there is any difference between the various cooking oils. However, he already believes there are numerous applications for this research within the food processing industry, including prevention of cross-contamination in large food packaging factories and industrial kitchens. “I think what’s different about our work is that it’s super simple. We’re not changing the surface of the steel, we’re adding that molecule to the surface, but that’s the only change we’re making” Hatton said. “I think this kind of thinking can work for other things in the food industry, absolutely, food packaging.” “Keeping the bacteria stuck on the surface is critical,” he added. “Killing bacteria is one way to do this, but if you can stop them from joining, that’s important.”

Most people never think about how the products they use every day are made.

Whether it’s the ceramic tile in your kitchen, the battery powering your phone, the paint on your walls, or the materials used in aerospace and medical applications, many products begin as raw powders. Before those powders become finished goods, they go through a series of processing steps that determine everything from product quality to production efficiency.

But while every step matters, there’s one thing manufacturers learn quickly: the process is only as reliable as the equipment behind it.


It All Starts with the Material

Raw materials rarely arrive in the perfect condition needed for production. They often need to be blended, dried, classified, or reduced to a specific particle size before they can move to the next stage.

That may sound straightforward, but small inconsistencies can create big problems.

A slight variation in particle size can affect how materials blend. Poorly processed material can impact product performance. And when production schedules are tight, even a brief interruption can create a ripple effect throughout the entire operation.

That’s why manufacturers place so much emphasis on consistency from the very beginning.


The Step That Often Determines Everything Else

Every stage of powder processing contributes to the quality of the finished product, but particle size reduction often has the greatest influence on everything that follows.

In industries like ceramics, even small variations in particle size can affect surface finish, strength, and overall product quality. Consistent milling helps manufacturers maintain tighter process control from batch to batch.

This is where ball mills play a critical role.

For decades, ball mills have been one of the most trusted methods for achieving uniform particle size and creating consistency throughout the manufacturing process. While the technology itself is proven, what really matters is how reliably the equipment performs over time.

Because in manufacturing, consistency isn’t achieved through occasional success. It’s achieved through repeatable performance every single day.


The Reality of Downtime

Ask any plant manager what keeps them up at night, and there’s a good chance downtime will be near the top of the list.

When a critical piece of equipment goes down, production doesn’t just slow down—it can stop altogether.

Production schedules slip. Customer delivery dates get pushed back. Operators sit idle while maintenance teams troubleshoot the issue. What starts as a maintenance problem can quickly become a much larger business challenge.

That’s why reliability isn’t simply a maintenance concern. It’s a production concern. It’s a profitability concern. And in many cases, it’s a customer satisfaction concern.

Manufacturers don’t just need equipment that works. They need equipment they can count on.


Built for the Long Haul

The best processing equipment isn’t necessarily the equipment with the most features. It’s the equipment that shows up every day and does its job.

Industrial environments are demanding. Equipment faces abrasive materials, long operating hours, and constant production pressure. Reliability isn’t something that’s added later—it’s something that must be engineered into the machine from the beginning.

That’s one reason ball mills continue to be trusted across so many industries. When designed and built correctly, they provide dependable performance for years while helping manufacturers maintain consistent product quality.

In many cases, the lowest-cost machine becomes the most expensive option when maintenance costs, replacement parts, and lost production time are taken into account. That’s why experienced manufacturers evaluate equipment based on total cost of ownership, not just the initial purchase price.


Why Reliability Matters More Than Ever

For decades, Orbis Machinery has worked with manufacturers across industries to solve particle size reduction challenges and improve process reliability.

In today’s manufacturing environment, reliable equipment becomes more than a production asset—it becomes a competitive advantage.

Reliable milling equipment helps create predictable outcomes, reduce waste, minimize downtime, and support long-term operational success. When manufacturers can trust their equipment, they can focus less on troubleshooting and more on growing their business.
