Calculate pellet durability with this formula: Pellet durability = Weight of the whole pellets (500 x 100). If the two samples vary more than +/- 2%, prepare a third sample from your reserve and retest. Indicate time in hours between cooling and test as a subscript of the pellet durability figure.
Pellet durability tester is a useful device for testing the texture of feed pellets (Fig. 3.20). Take test pellets of diameters 9 to 20 mm, length up to 30 mm, totalling approximately. Fig. Pellet durability tester. 100 grams. After testing, express the final weight as percentage of original weight to give the durability value. For example
The New Holmen Pellet Tester is more severe than the Tumbling Can; the New Holmen Pellet Tester gave a durability of 64.9 in broiler pellets while the Tumbling Can gave 89.1. Adding two ¾-inch hex nuts to the Tumbling Can dropped durability to 68.2. Experience suggests the more severe test better reflects conditions in the industry.
The results of the tests are interpreted as a standard measure of quality, which is referred to as the Pellet Durability Index (P.D.I.) The test is simple to perform and requires a minimal amount of equipment. The procedure:: 1. Secure a representative sample. 2. Remove broken pellets from sample with appropriate hand sieve. 3.
