Company

Metropolitan Bread & Bun Bakery in the USA.

Application

In-line pressure board Transfer conveyor.

Challenge

This conveyor is a “Belt Killer” application because of the age of the equipment, directional changes, small pulleys and rolling nose bar.

Downtime

  • The line consists of 9 belts on which ALL of their products, (30+ dough consistencies and shapes), travel across. The belts run 16-18 hours a day / 6 days a week. A breakdown during their production schedule has the potential of completely shutting the line down causing thousands of dollars of lost through-put.
  • The average belt life of a properly installed 2 Ply Mono-filament urethane impression top belt is 8 to 10 months.
  • Average Spiral Laced belt life is 4-6 weeks.

High maintenance costs

  • 2 ply Impression-top urethane belts average install time – 3 to 4 hours.
  • Spiral Laced spare belt is kept in stock just in case the endless belt tears unexpectedly.
  • Because of the aged equipment, pulleys and take-up rollers need to be adjusted weekly to track the belt.

Safety concerns

  • Fibers and plastic can contaminate the final product.
  • Operator adjusting the belt with hands and or by using improper tools.

Solution: 

Volta Homogenous Reinforced Flat Belt with ITO50 Textured Top & Endless Bias Splice.

Savings/Maintenance costs

  • Belt was installed on May 20th / 2020 (Still Running) and hasn’t required replacement or use of a spare. (Even though the Volta belt is 30% more in price, cost of ownership was reduced by 70% during this current time frame).
  • Maintenance spends far less time adjusting rollers weekly because the flexibility of the Butt weld LB material handles the reverse bends and nose bar more efficiently.
  • Collateral savings: ITO-50 Belt surface reduced the use of flour required to handle the various dough consistencies.

Safety Concerns

  • Since the belt tracks more effectively, edge fibers, when noticed, are easily removed with a Universal VAR heat iron.
  • Butt weld is performing better than a finger splice reducing the possibility of pieces of belt breaking off into the product.
  • Less operator involvement.

Client testimonials:

The belt has lasted two times as long as the standard belt without any additional installs, emergency use of the spare belt or regular maintenance adjustment attention.
