Frigopan Series

Retarder Proofers for 2 or more trolleys

Modular Retarder Proofers available in a wide range of dimensions and configurations, ideal to control the leavening of bakery and pastry products. By managing temperature and humidity the leavening process can be slowed down, to allow the baker to prepare it during the day and find it perfectly leavened and ready for baking the next morning.

Retarder Proofer advantages

No more night-time work

The product can be prepared during the day and put into the retarder proofer, to get it the next morning perfectly leavened and ready for baking at the desired time

Higher and constant product quality

The productive process becomes repeatable and is not influenced by the environment temperature

Cost reduction

Thanks to the optimization of personnel use and the increased standardization of the productive process

Retarder Proofer cycle

Thanks to its humidity and temperature control, the Retarder Proofer cycle allows with its 4(+1) separate phases to delay and control the leavening process and obtain a perfectly leavened product at the desired time.


Rapid cooling to block yeast activity


The product is kept at low temperature, the rising process is still suspended


The temperature begins to slowly rise, the rising process restarts


The proofer slowly reaches the set temperature and humidity, the rising process is completed

Rising block

Optional step to block the rising once again by reducing the temperature, useful to keep the product ready for baking at a later time

Retarder Proofer at night, Proofing Chamber during the day!

A Retarder Proofer fulfils its main duty at night but can also be profitably used during the day as a proofing chamber

Retarder Proofers can work in both heating and cooling mode, which means they are able to ensure a better leavening process compared to traditional proofing chambers with heating system only.


With a Retarder Proofer it is always possible to reach the desired temperature and humidity in every season, even the hottest ones, ensuring an uniform leavening with a constant duration.

Uniform air and humidity distribution

Alaska Retarder Proofers stand out for the presence of the components dedicated to adjust their internal conditions along the whole depth of the chamber:

  • Evaporators for cooling
  • Steam diffusor for humidity control
  • Resistances for heat generation
  • Fans and internal panels for airflow direction

Only in this way a uniform humidity and air flow can be ensured, leading to a final product of higher quality and uniform leavening in every point of the chamber. This prevents technological issues such as “skin” effect on the product surface or different leavening stages in different points of the chambers
