What does AD mean in FOOD & NUTRITION

Air Drying is an effective, efficient and cost-effective way to dry materials with minimal risk of damage to the item being dried. It can be used in a variety of environments, regardless of humidity or temperature. Additionally, it is non-invasive compared to other drying methods, making it ideal for materials that cannot withstand certain temperatures or chemical processes.

Not all materials are suited for air drying due to their composition or sensitivity. Items like electronics or fragile organic materials may not be suitable candidates for air drying because they could be damaged by evaporation or exposure to fluctuating temperatures during the process. Additionally, if more than 20% relative humidity exists in the environment, there will be insufficient evaporation taking place.

Generally speaking, no significant shrinkage occurs when air drying textiles because temperature fluctuations are avoided throughout the process since only air is being circulated around the material. However, if temperatures become too high during any stage of air drying then there is potential for fabric shrinkage even when using this method.

The length of time required for an air drying cycle is dependent on several factors including environment conditions (humidity and temperature), size and weight of material being dried and amount of moisture present within that material. Generally speaking however, most materials can dry in 2-3 hours under ideal conditions.

Generally speaking, some basic maintenance should be done annually on an air dryer in order to ensure optimal performance during usage including checking fans and motors as well as checking electrical connections and wiring integrity periodically throughout its lifetime in order to protect against overheating from any defective parts which could lead to fire hazard risks.
