Caking

Caking refers to the undesirable formation of solid lumps in powders or granules due to factors like moisture absorption, temperature changes, or prolonged storage under pressure. This phenomenon reduces flowability and affects processing efficiency, posing challenges for industries such as food, pharmaceuticals, and chemicals, where material consistency is essential.

On this page, explore the underlying mechanisms of caking, its impact on product quality, and effective strategies to mitigate it. From controlling environmental conditions to modifying material properties, learn how to prevent caking and maintain optimal material performance.

    Powder Caking Prevention: Causes, Testing Methods, and Proven Fixes

    Powder caking can be predicted and, in most cases, prevented. It follows a small set of traceable mechanisms, so it is not guesswork. Use DVS, shear, and dwell tests to pinpoint the onset. From those results, define storage windows with real numbers instead of rules of thumb. Then design hoppers, packaging, and climate [...]

    Why Your Powder Doesn’t Flow the Same in Summer

    Humidity and temperature shifts in summer can drastically alter powder flow behavior. By controlling the environment, adjusting equipment, and testing under real conditions, you can prevent flow issues before they disrupt production. Learn more in this article about Powder Flow in Summer How [...]

    Selecting the Right Powder Mixer for your blend

    There is no one-size-fits-all powder mixer—the right choice depends entirely on your powder’s flowability, sensitivity, particle size, and process needs. Whether you need gentle handling for fragile particles or intense shear for cohesive blends, matching the mixer to your material ensures better blend quality, efficiency, and product consistency. Selecting the wrong mixer can [...]

    Measuring Hygroscopicity in Food Powders: Why It Matters More Than You Think

    Check out these related articles: https://powdertechnology.info/moisture-content-analysis-in-powder-samples/ Hygroscopicity — a powder’s tendency to absorb moisture — directly impacts shelf life, flowability, and product quality. Measuring it through sorption isotherms or DVS helps food manufacturers prevent caking, preserve texture, and design smarter packaging. Ignoring it risks product failure. [...]
