GRAVITY FEED VALVE - HOW TO OPERATE
AND MAKE ADJUSTMENTS
The Gravity Feed Valve consists of two tubes, one sliding inside
the other, and a plunger/splash guard.
The inner tube blends the flow of air and mix into the freezing
cylinder. Air enters through the top of the tube and the mix,
through a triangular hole at the base. See illustration below.
The outer tube is actually a valve. Lifting the outer tube varies the
size of the hole and the amount of mix that flows into the freezing
cylinder. The size of the air inlet, at the top of the tube, does not
change so the amount of air that enters the freezing cylinder is
constant.
You can vary the overrun (yield) by letting more or less mix enter
the freezing cylinder by manually regulating the valve.
The plunger/splash guard keeps the mix. from splashing on the
mix tank cover and serves as a device to eliminate potential
clogging inside the tubes.
You may find it necessary to adjust the position of the outer tube
in order to regulate the amount of mix entering the freezing
cylinder after start-up. Actually, sales conditions will dictate the
proper adjustment.
If more production is required, increase the opening by lifting the
outer tube, and conversely when business is slow, push down
the outer tube, reducing the opening. Naturally, when the mix
runs low in the mix tank, you will open the slot more and
eventually take the feed tube out completely to use the last of mix
in the mix tank.
