For this kind of production, I would first define what the factory actually means by “pepper grinder.” If the target is dry pepper powder or granules, the process requires dry size reduction and the colloid mill should not automatically be treated as a replacement for a conventional dry grinder. A colloid mill becomes relevant when the final product is a pumpable pepper paste, puree, suspension or sauce base, where wet grinding, dispersion and homogenization are required. The feed condition, initial particle size, solids content, viscosity and required final texture should therefore be established before selecting the mill. This article gives a detailed comparison and explains how the equipment fits into a pepper-processing line: https://mill.globecore.com/pepper-grinder-dry-spice-grinding-vs-wet-colloid-milling/.
