Unless absolutely needed I would not consider using a moisture absorbing substance. The answer from Asia was very good. The temp:moist relationship is very important as it relates to the equilibrium point. The one place I might consider using any of the materials Asia discussed would be the pre-mix room/storage area. Many of those ingredients are highly hygroscopic and will clump in bags or micro-bin systems. Storage turn-over time is very important.

Several types of moisture-absorbing materials can be used in storage areas to prevent damage from humidity, including silica gel, desiccant clay, molecular sieves, and activated carbon. Other options include calcium chloride, charcoal briquettes, and even natural materials like cotton, wool, or jute.

WHAT TYPES OF MOISTURE ABSORBING MATERIALS CAN BE USED IN FEED STORAGE AREAS?

The following should be considered as general information only, however, you should always seek professional advice, specific to your individual circumstances.

Desiccants are valuable tools for managing humidity and protecting feed from moisture-driven spoilage, but they are most effective when used as part of a broader, integrated humidity control strategy. Relying solely on desiccants in large or open feed storage settings is not sufficient for robust, long-term moisture management.

In large, open spaces, their effect is limited versus the constant influx of humid air. n areas with persistently high humidity, desiccants can become overwhelmed quickly, which may lead to gaps in protection unless replaced very frequently.

For areas storing feed or ingredients, use only desiccants certified as feed-safe.

Silica Gel – a porous, granular form of silicon dioxide, that is inert, non-toxic, odorless. It has high moisture-absorption capacity, is non-toxic and feed-safe, and is reusable through oven drying.

Calcium Chloride – is a hygroscopic salt that absorbs water and forms a brine. It is fast-acting, and absorbs high amounts of moisture, even in high humidity. Generally considered single-use, as regeneration is impractical. Calcium chloride should only be used when securely contained and kept separate from direct feed contact.

Clays – such as bentonite are natural, non-toxic, biodegradable, inexpensive, and eco-friendly. Once saturated, clay desiccants must be replaced, as they are generally not reusable.

Activated Alumina – features high absorption capacity, non-toxic, and is effective in higher temperature storage areas.
