The effects of freeze, dry, and wet grinding processes on ...

This study attempted to replace the wet grinding process of rice with a freeze grinding process. The freeze grinding process involved soaking the rice samples in liquid nitrogen before grinding in a dry grinding machine. Three different types of grinders (hammer mill, roller mill, and pin mill) were used in both the freeze and the dry grinding processes.

Impact grinding is most efficient with dry, low-fat ingredients, although many other materials may be reduced in size by proper screen selection and regulated intake. Most hammermills have a horizontal drive shaft which suspends vertical hammers but for some ingredients, such as dried animal byproducts, a "vertical" hammermill is more efficient.

A Brief Cultural History of Mesquite - Archaeology Southwest

(June 12, 2020)—Since moving to Tucson, I find June to be a welcome time of transition. The atmosphere shifts from hot and dry at the beginning to, well, hotter, but not so dry by the end as the summer monsoon sets in. Usually as the spring semester at the University of Arizona wraps up (not this year due to the pandemic), many students abruptly leave for the summer.
