These running schedules are a starting point for you.
They are for “average” room conditions, which are approximately
68 - 70º F (22º C), and 45 - 55% humidity. As you know,
higher temperatures cause faster gelling, and higher humidities
cause faster gelling. The opposite is true for colder and drier
conditions.
Using more Foaming Agent causes higher rise (softer) foam, and extends
the gel time. For denser foam, use less Foaming Agent, and turn
the mixer speed down to #2 a minute or two earlier.
Hobart mixers have a “dead” spot inside
the whisk. On speed #1, the foam inside the whisk does not mix thoroughly
with the rest of the foam in the bowl. It is therefore useful to
use the side handle to drop the bowl while the whisk is turning
at speed #1. This should be done several times throughout the refining
period, and at least two or three times after the Gelling Agent
has been added. Drop the bowl and let the whisk rotate for a few
revolutions. Much of the foam will drain out of the whisk and into
the bowl. Then raise the bowl as usual.
When your batch is finished and the mixer is turned
off, you’ll need to unhook the whisk before removing the bowl.
Now you can take the bowl off its pegs and remove the whisk. Gently
shake the foam out of the whisk and into the bowl, so you don’t
waste.
We strongly suggest the use of GM Flow Increaser with
large batches. It allows the foam to refine better and pour easier.
We use approximately 3gms/ 150gms. latex. Large batches can be made
even better with the use of Micad and Cell Choke. Call for details.
