Around the late 18th century, the milling industry dramatically changed with the invention of the roller mill - a type of machinery with a series of rollers that grain passes through to separate the endosperm from the bran & germ, leaving behind a white, fine, starchy flour. This not only created a softer, more palatable flour, but more importantly, it sped up the …
Automatic's industrial grain roller mills produce precise particle size every time, even when it comes to high volume grain processing – as much as 15,000 bushels an hour for our hardest-working, high-capacity models.
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change its cross-sectional area. The types of rolls used …
Each method produces a distinct tequila with its own flavor characteristics — the roller mill produces tequila with fruity citrus notes, and from the tahona we get earthy, vegetal tequila. Our house style blends the two tequilas and their distinct flavor profiles to create a balanced, complex end product in Patrón Silver.
