Process improvements in one area can often have beneficial side-effect across an entire line.  Read more and see how JetAir's high-speed centrifugal blowers and air knife systems in a custom engineered system can improve the bottom line in more than just one way.

Problem

A large tomato processing facility in Southern California using traditional washing, brushing and radial blower technology wanted to grow but could not!  Adding throughput would require more space or faster line speed.  In their case, finding space was impossible and increased line speed overwhelmed the system's ability to dry tomatoes.  Too much wetness resulted in additional downstream process problems as well as quality issues in packaged products.  They felt stuck!

Solution

After reading about JetAir's industry leading efficiency, the plant engineer contacted JetAir Technologies about the possibility of using a high-speed centrifugal blower to replace the radial systems in place.  JetAir applications engineers visited the plant and determined that they could integrate a high-speed centrifugal drying system onto their existing line and by locating the system at the discharge of the washer they could isolate 90% of the blown-off moisture near the washer keeping brush rollers dryer and less likely to rewet tomatoes.  Plus, line speeds could be accelerated 20%+ with no excess moisture on the tomatoes and no downstream process problems.  But the bonus they didn't expect was the discovery that they could remove almost 15' of line.  "Wow, those jets really work... and look how dry the brush are..!"

Follows is a drawing of the custom engineered JetAir System.  It is made to enclose the blowers and electronics; and protect them in a washdown environment.  It is als o designed to fit precisely over the conveyor, supported by existing conveyor side walls.  It is a simple design requiring minimal installation time.

JetAir Tomato Air Knife Drying System

The tomato company also looked at compressed air to dry tomatoes but found the higher pressure and lower flows of compressed air damaged tomatoes and didn't "reach" to the brushes, meaning more tomatoes rewet.   Further, the compressed air solution required two rows of 30x fan nozzles consuming over 120kW of power compared to JetAir's (2)x High-Speed Centrifugal Blowers consuming 30kW!  The energy savings were enormous not to mention the space and noise issues avoided.
