DEVELOPMENT OF RED-PEPPER CRUSHER

Red pepper powder is produced from dried red pepper through milling process with roller mill. Traditional Roller mill is convenient for crushing wax and fiber parts in red pepper. However, some metallics are produced by the friction of two rollers when it operates without feeding of red peppers. In order to reduce this metallic problems created in the roller mill in the process of red pepper, a new roller mill mechanism which enables two roller to apart when red pepper is not fed between two rollers was introduced. Adjustment of clearance between two rollers was able to conducted by the current difference between idling and crushing process. Two types of roller surface, grove and flat, and two different roller mills, cast iron and Ti coating, are tested and compared in this experiment.
