The Solution: The dairy, which produces and
sells sour cream and cheese cream under several brand names,
requires a unit which will operate at a variable speeds to
feed milk powder and salt for the production of cream cheese.
Because the dial control on the original unit was not accurate,
it would feed too fast or bottleneck. In addition, the wire-type
screw that was used would twist when powder built up in the
discharge tube, hampering or halting feed.
The Metalfab DB1-2's hand-controlled dial feed allowed easy,
variable operation. Interchangeable screw and tube combinations
permitted changes in feed rate beyond those obtained through
the variable speed drive.
The stainless steel DB1-2 has only five moving parts - the
drive, coupling, screw and two bearings - minimizing maintenance
and assuring long life. The unit features a five cubic-foot
hopper with 70° sloped sides and a large rectangular outlet
to assure the positive flow of powders, pellets, flakes and
agglomerates used in the food, chemical plastics, pharmaceutical
and other processing industries. The DB-2 has a maximum feed
rate of 20 cu. ft./hr., but other units are available with
rates of up to 550 cu. ft./hr.
