The Holmen NHP100 is Tekpro Limited’s entry-level pellet durability tester used for calculating the Pellet Durability Index, also known as the PDI, of feed pellets or extrusions by simulating pellet transportation environment from mill to trough. The complete Holmen range of Pellet Testers represents the culmination of over 20 years of involvement within the pellet manufacturing industry. The range consists of four models including the ever-popular Holmen NHP100, which is supplied complete with a 2.5mm diameter mesh hopper as standard, although other mesh sizes are also available to suit aqua, poultry, kibbles, extrusions, and larger cattle feed types.
Versatile Pellet Test Machine
The Holmen NHP100 portable pellet durability tester is a truly versatile entry-level machine. Being portable it can be easily transported between different testing locations, requiring only to be placed on a flat stable surface to provide basic results for the operator. It works by loading a pre-sieved sample of pellets into the test chamber which cascades them in an air stream causing the pellets to collide with each other and the perforated hard surfaces within the test chamber. When testing is complete the pellets are removed for manual weighing. The 'pellet durability index' (PDI) is the difference between pellet weight before and after the test recorded as a percentage. The tester provides the ability to manually calculate test results with limited repeatable accuracy. The operation is manual with a basic timer function only, unlike the manufacturer's more advanced Holmen NHP200 where test length is adjusted according to pellet diameter.
Holmen Testers Increasing In Demand Globally
The basic NHP100 is a popular machine for smaller companies, but quality-focused feed mills typically now prefer the NHP200, this is due to its ease of use and the repeatable accuracy of the test process. For larger companies who manufacture pellets in bulk, Tekpro can also provide the Holmen NHP300, together with inline samplers to test directly after the press, before too much product has been produced, this can significantly help reduce the need for rework and optimize production efficiency. The NHP100 has always been a very popular machine since its original launch, but as feed mills further strive for greater levels of automation and consistent repeatability of processes, both the Holmen NHP200 semi-automatic and NHP300 inline pellet durability testers from Tekpro have significantly increased in demand from all around the globe.
