Retarder Proofers

What is a Bongard Retarder Proofer?
A Retarder proofer is a computer controlled freezer, fridge
and proofer combined, that work together to ensure its
contents are held and manipulated to give pre-desired results,
depending on time, and day of the week.
How does it work?
The retarder proofer cools (retards) and holds its contents
in a controlled environment until a pre-programmed time where
it switches over to ambient mode, to gently thaws out the
contents, and very slowly starts to prove; so when the bakers
arrive in the early hours of the morning, the contents are
ready for baking.
Basic operation
A. The yeast products are placed into the retarder proofer
before the end of the days production.
B. The refrigeration unit on top chills the products and
retards the yeast from activating. The unit then holds the
product at approx 2-4 degrees.
C. The heating/humidifying unit inside the proofer will then
start to bring up the temperature inside the cabinet and
slowly start to prove.
All stages are controlled by the programmable computer on the
front at the top. All the operator has to do is tell it what
time you intend to start work the next day, and the computer
does the rest!

Machine components and structure
How can a Retarder Proofer benefit my business?
Labour saving - staff work during the afternoon preparing the
next days early production = Lower wage costs
Staff retention – staff start later, meaning better working
hours and conditions. Meaning that good staff are easier to
keep
Ease of operation – anyone can use it
Safe and reliable
Better product quality and taste. The controlled slow
fermentation increases the flavour of the product
All croissants, Danish Pastries, snails, scrolls, rolls,
loaves, baguettes etc… can be retarded, and given the
differing proof times, the product flow through the oven is
easy.
How do I have different products ready at different
times?
There are 2 ways:
Firstly, we all know that different products take different
times to prove, so a baker knows that a white block loaf
takes less time to prove than a cheesymite scroll, therefore
if you tell the retarder proofer to be ready when you get to
work, the scrolls can continue to prove while the blocks are
baking!
Secondly, you can get a Retarder Proofer in almost any
configuration; therefore you can have 2 or 3 separate
retarding/proofing compartments in the 1 retarder proofer,
allowing different cycle times as per your mornings
production. (E.g. 1 compartment with the white blocks can be
programmed to be ready at 4am, while the next compartment can
be programmed to be ready at 4.40am or anytime that suits.
Perhaps even an afternoon bake?)
If you have a multi compartment unit, you can even use 1
compartment as a fridge if needed
Where will I put it?
Retarder Proofers are available in many configurations, to
fit almost any bakery, with any production requirement. Most
clients replace their standard Proofer with a Retarder
Proofer.

Retarder proofer BFA
Cooling unit ready for use with refrigerating fluid R 404 A
preserving the ozone layer. Cont rol panel with electronic
controls (BFA and BFC alike) with reheating by levels and/or
constant increase of the temperature (degree per degree) with
stabilisation of the temperature in hot cycle, and possibility of
“dormillon” (if after a period of 45 min following programmed
fermentation cycle, nobody has withdrawn the product, the cabinet
goes back to a temperature of 15° C: values are adjustable).
