Food Choppers and Meat Grinders
Food choppers and meat grinders are of heavy, substantial tinned iron. The
principle upon which they are operated is known as the screw motion, which is
used whenever it is necessary to produce great pressure. The food is fed into
a cylinder through which a spiral rod the feed screw advances when the handle
to which it is attached is turned. The feed screw carries the food to the cutting
ends and forces it against sharp knifelike edges with openings between, through
which it falls into a receptacle. The screw carries all the food to the cutters
and leaves the barrel empty.
The degree of fineness with which the food is cut depends upon the distance
apart of the cutting edges. If they are close together the food will be finely
cut; if far apart, coarsely cut. Three sizes are usually provided with the chopper,
fine, medium, and coarse. Sometimes an extremely fine cutter, called a nut butter
cutter, is also added. A chopper should cut rather than squeeze the food apart.
Choppers and grinders have long handles, which give greater power than short
ones.
Grinders come in three sizes. The largest size, which will chop two or three
pounds of meat a minute,
is too large for ordinary family use, and the medium and small sizes are those
generally sold.
Grinders should be washed with hot water and soap immediately after use.
Chopping knives and bowls produce the same results but with more labor and
time, as half the time and strength are wasted in raising the knife. However,
the old-fashioned method is preferred by those who wish to preserve all the
juices of meat or fruit. The bowls are made of basswood, cottonwood, and maple,
turned out on lathes, and often sold in nests (one inside another). Some bowls
are oblong in shape. Bowls should be cleaned as soon as used, and water should
not be allowed to stand in them as it will warp and crack them.
