what does a retarder do
A retarder is a device used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles. Retarders serve to slow vehicles, or maintain a steady speed on declines, and help prevent the vehicle from running away by accelerating down the decline. They are not usually capable of bringing vehicles to a standstill, as their effectiveness diminishes as vehicle speed lowers.
The retarder controls and optimizes the leavening process with precision, without compromising hygiene and quality, producing improved aroma and fragrance compared to foods subjected to the traditional, natural leavening process.
