Abstract
An apparatus and method for controlling the moisture content of prilled products which are produced by air drying a spray of the liquid product, comprises a vessel for receiving a flow of air and a flow of the liquid product (10), a supply line for supplying air to the vessel (14) and a supply line for supplying liquid product to the vessel (16). The product is advantageously a solution of urea. Moisture content is measured or inferred for the product flow, the input air, and the air coming out of the vessel. An air flow controller (24) is connected for controlling the flow of air (14) into the vessel (10) which controller is itself controlled by a circuit that calculates the required air input flow rate for a desired moisture concent in the prilled product.
