"We have been using the Whirlwind ES4 for grinding rework and are more than pleased with the results. The ES4 has cut our rework process down by 75%. Additionally, the quality of the product has increased by giving us a more uniform size product to work with. The ES4 has also benefited us by using it as a sifter. We occasionally receive dry ingredients that have clumps or have clumped over time. Sifting through the Whirlwind has allowed us to completely get rid of any clumps that may be present. The machine is fast, easy to use, and easy to clean! I recommend the ES4 and I am very pleased with the performance." - Bob Bakker, Little Dutch Boy Bakeries, Inc.
