Prémoagem

Pré-moagem, or pré-moagem, is a preparatory milling or crushing stage used before the main milling or extraction steps in various industrial processes. It consists of coarse crushing, shredding, or breaking of raw materials to increase surface area, disrupt fibrous structures, and create a more uniform particle size. The main objectives are to improve extraction or processing efficiency, reduce energy use in later steps, and facilitate handling and mixing, while aiming to minimize damage to the material.

The specific configuration of pré-moagem varies by industry and facility. Equipment commonly used includes crushers, shredders, and preliminary roller mills, sometimes combined with conditioning steps such as adjusting moisture content. The operation is designed to be compatible with the downstream process, whether it is milling, juice extraction, paste formation, or fermentation.

In sugarcane processing, pré-moagem refers to an initial mechanical treatment that fragments the cane to enhance juice extraction and reduce clogging or wear on subsequent mills. In olive oil production, pré-moagem denotes the initial crushing of olives to form a paste, preceding malaxation and oil separation; the method and equipment (hammer mills, disc crushers) influence paste texture and oil yield.

In grain and cereal milling, pré-moagem may describe pre-crushing or conditioning of grains to achieve better milling efficiency, uniformity, and flour yield, potentially lowering energy consumption and equipment wear. Across applications, the use of pré-moagem depends on material properties, process design, and desired product quality, and it is not universal in all facilities.
