Loaf Volumeter to Top

LOAF VOLUMETER National Manufacturing Company
L incoin, Nebraska
Price: $100. 00

Directions: For volumes over 900 cc:

Preparation

1 .Place 900 cc. dummy loaf in container (C) and close latch.

2 .With gate open between seed reservoir (R) and container, allow seed to fill the space around the dummy (evidence: visible seed in the column).

3.Close the gate and invert the uncovered reservoir to pour out excess seed. (Pour into large container, such as dish pan.)

4.Swing into "up" position. Cover reservoir, open gate, and swing reservoir down to allow seedto run from the container to the reservoir (slap container to free last seeds). Close gate and return to "up" position,

Measurement

1.Replace dummy with unwrapped sample and close latch.

2.Open gate with a quick, smooth motion and allow seed to run into container without interference ox jarring. When the flow of seed stops, read sample volume (in cc.) directly on the column.

3.To prepare volumeter for next reading swing reservoir down, allowing seed to flow into it, slap container, close gate, and return to upright position. Remove sample and replace with new one.

For Volumes Under 900 cc:

1.Proceed as above except: During the preparation phase add extra seed to a definite reading on the column (with the dummy in place). The amount of extra seed to be added will depend on the sample size. For example, if volumes in a test series run as low as 500 cc. (but no lower), it will be necessary to add 400 cc. extra seed to a reading of 1300 with the dummy in place. Readings of volume then will be corrected by subtraction of 400.

LOAF VOLUME BY STANDING HEIGHT

1.Cut a slice (1/2-inch thick) from the center of the product.

2.Lay the slice of the product on a piece of paper. Trace around it with a soft pencil, keeping the angle of the pencil the same throughout the tracing procedure. Be careful not to press the product out of shape.

3.Draw 5 perpendicular lines on the tracing: (1 and 2) at each end, (3) in the center, (4 and 5) half way between the center and each end. Measure the height of each line in cm. Average the 5 measurements for standing height value.
