“PK” Pastry Knife
Used for cutting flour and shortening together in a pie dough, pastry
shells and for cutting lard or shortening into flour. The “PK” pastry
knife should always be used for such work so that pie crusts, etc, are
mixed with as little rubbing as possible and so that the shortening will
be in small pieces to produce a flaky product.
Bowl Extension
Extension Rims are merely vertical sided splash covers. They are
not covers in form but do provide higher side walls to prevent throw-
out of ingredients. Usually they are not recommended because they
are invitations to overloading a machine beyond its point of maximum
efficiency. Extension rims permit more air to enter the bowl and
prevents splash of light ingredients.
The true capacity of a mixer is not the amount of material that can be put in the bowl or the amount of
the total batch which can be mixed with in the power of the motor. The true capacities and the most
efficient (therefore the best money makers) are the ideal loads which permit a Mixer to operate at
peak efficiency, so far as development, yield or aeration have their effect on the mixing operation.
Splash Covers
These items provide means for providing splash of throw-out on
certain mixers when, for reasons of speed, the operator prefers to
start in a higher speed or progress quickly to a high speed in order to
complete a batch. These are valuable accessories but would not be
used to increase the mixing capacity of any particular machine,
beyond its recommended maximum.
They are convenience items, not capacity increasers. The best functioning of Blakeslee mixers
depends on leaving room for proper material aeration or manipulation. Use splash covers or
extenders only for containing ingredients. They are efficient for their intended use, but if a mixer is
overloaded and a Splash Cover is used, aeration is reduced due to restriction in the area where air
enters the mix. The capacity chart located on the column of the mixer is a good guide for maximum
efficient use for the Mixer. Experience will have to dictate exact top capacity and Splash Cover use
under your own needs.
