WEIGHT and MOISTURE of THRESHED BEANS
Thresh and hull only pods with developed beans from both units. If pods are too wet to thresh easily, pods should be dried
for a short period at no more than 70 degrees C and then threshed.
6. Weight of all threshed beans from both units immediately before moisture test. .............

If sample weight is too small for moisture test, sufficient grains of known
moisture content will be added to the sample so that a moisture test can be made.
The moisture content of the sample can then be derived using the following
formula.
E=

( A + B ) D - ( B x C)
A

Where A = Weight of small sample (item 6) .........................................................

. ____ ____ Grams

B = Weight of additional beans required for moisture test ........................

. ____ ____ Grams

C = Moisture percent of B .........................................................................

. ____ Percent

D = Moisture percent of A + B combined ..................................................

. ____ Percent

E = Result: Moisture percent of small sample (enter in item 7) .................

. ____ Percent
