How CinchSeal Rotary Shaft Seals Make Ribbon Blenders More Efficient

Today, bulk food production is standard in America. A lot of the products that you find on store shelves have been mixed in large ribbon blenders. The rotary shaft seals in these industrial blenders are what keeps them running smoothly, keeping the products inside safe and uncontaminated. Here’s a closer look at how CinchSeal’s custom rotary shaft seals make ribbon blenders more efficient.

What’s a Ribbon Blender?

A ribbon blender is an industrial trough for blending products together. The horizontal trough has a shaft through the middle that has mixing blades attached to it. The blades have a double helical (ribbon) design.

Ribbon blenders are used in a variety of applications, from the food processing industry to making chemical mixtures, dry cleaning powders, and cement.

How a Ribbon Blender Works

The shaft inside the ribbon blender rotates, causing the ribbon blades to spin. Product closer to the shaft moves in one direction, while product further away from the shaft moves in the opposite direction. This creates an even blend, whether it’s dry cake mix or a slurry paste for yogurt. The trough, shaft, and blades are typically constructed from stainless steel or other high-quality metals to prevent contamination and make them easy to clean between uses.

Where Do Rotary Shaft Seals Come In?

The shaft inside the ribbon blender needs a seal on one or both ends depending on the machine. Rotary shaft seals keep the product inside the ribbon blender’s trough while preventing contamination from the outside. CinchSeal offers several types of seals that prolong the life of ribbon blenders by eliminating shaft wear often caused by packing seals, and providing easy installation and maintenance.

Importance of Rotary Shaft Seals

Imagine what could happen to a food processing or manufacturing business if their only rotary blender doesn’t have a tight shaft seal. If products leak out from inside the trough, the bearings could wear out and lead to machine failure. Production would be shut down until new parts arrive and the ribbon blender is repaired. Even worse, unwanted product could leak into the trough and contaminate the batch. This could result in product recalls, safety inspections, and potential lawsuits. Preventing these scenarios is why rotary seals are important.

Ribbon Blenders & Rotary Shaft Seals are a Perfect Match

Across their many industrial and food service applications, ribbon blender rotary shaft seals provide:

  • Prolonged machine life
  • No contamination or product leakage
  • Heat resistance up to 400 F for continuous operation 
  • Fast, easy repairs and maintenance 
  • Reduced downtime and productivity loss
  • Fast ROI
