Bakers use sugar icing for many bakery goods. However, sugar is extremely hygroscopic and therefore absorbs moisture very readily.

Bakery Applications

  • Freezers & coolers
  • Pneumatic conveying systems
  • Production areas
  • Storage areas

Effects of Uncontrolled Humidity

Bakeries have a silent enemy: humidity. It attacks at the most inopportune times and causes issues that slow or stop production, turns good products into scrap and challenge even the most efficient and well-managed production team.

Humidity is easily absorbed by hygroscopic ingredients like sugar and flour- staples of the bakery industry. When they absorb moisture they become sticky, moldy, or just totally unusable in the process. Humidity also can cause wet, slippery floors posing a safety hazard for workers.

Many bakers chill or freeze part-baked goods. However, condensation in spiral coolers or build-up of ice in spiral freezers due to the storage of products with high moisture content and ingress of humidity can cause frequent production delays, waste, and defrosts. When air enters the spiral cooler or freezer via the inlet and outlet openings, it condenses onto the cold surfaces. Production has to be stopped regularly to completely wash, clean, and defrost the cooling or freezing equipment. Temperatures then have to be reduced to the correct operating level before production can be restarted.

The commercial implications can be considerable: many hours of downtime for cleaning and unclogging pneumatic lines, tons of materials wasted, poor product quality, worker safety issues, and slowed or stopped production. This all can add up to production issues, quality issues, loss of revenues and frustration.
