Title: Dryer Sizing Description: This video shows the steps involved in designing a dryer. Velázquez Martí, B. (2021). Dryer Sizing. http://hdl.handle.net/10251/168571 Automatic description: In this video, the presenter, whose name is exemplified by "Martí," explains the process of sizing an industrial dryer. The presentation aims to teach how to perform the sizing in a structured way in three fundamental stages: calculating the minimum mass flow rate of hot air required, determining the air circulation velocity, and verifying the flow rate of dried water along with the drying time. The first step details a mass balance to obtain the air mass flow rate, using data such as humidity differences and the mass of material to be dried. An example is presented where wood chips with specific moisture characteristics are to be dried, and a heat exchanger is used to reduce the relative humidity of the air. The second step involves calculating the air circulation velocity by analyzing the dimensions of the wood chips and the properties of the air, which depend on the temperature. The use of the psychrometric chart is mentioned, as well as how to calculate the volumetric flow rate and the minimum circulation velocity based on the dimensions of the dryer and the particles. Finally, the third stage consists of verifying the flow rate of dried water and calculating the drying time. A convective mass transfer equation is applied, and properties such as vapor pressure and relative humidity are used. With the data obtained, it is verified whether the amount of water that can be removed meets the requirements. The video concludes by inviting students to practice sizing the dryer using a new set of data and environmental conditions, encouraging the practical application of the concepts learned.
