Interpretive Summary: After peanuts are delivered by the grower to the buying facility, they must be stored in-shell in large bulk storage facilities. To minimize losses due to excessive mold growth or over drying, the space above the peanuts must be ventilated or air forced through the mass of peanuts. This process of ventilating the headspace and/or aerating the peanut pile exhausts excess moisture from the peanuts as they continue to dry and cools the peanuts. This study was conducted to determine the proper airflow rate for aerating these farmer stock peanuts. When the peanuts were aerated at a rate of three cubic feet per minute/ton of peanuts using a single tunnel and headspace ventilation, peanuts were cooled more rapidly than using headspace ventilation alone. Based on this research, recommendations for controlling the environment within a farmer stock peanut warehouse includes: 1. Change the air in the space above the peanuts once every two minutes 2. Force air at the rate of three cubic feet per minute/ton of peanuts up through a single duct down the middle of the warehouse and change the air in the space above the peanuts as in 1. 3. Force air through the peanuts at a rate of ten cubic feet per minute/ton of peanuts with no ventilation of the space above the peanuts.
