LEARNING THEATER PRESENTATION
Energy Recovery Analysis: Using the Conveyor Dryer To Dehydrate Fruits and Vegetables

Conveyor drying technology is a large consumer of energy used for a variety of applications, including food dehydration in the fruit and vegetable industry. As the world’s population increases, the enormous challenge of meeting food and energy needs are interconnected. The search for energy efficiencies to reduce the environmental impact of food production has accelerated. This presentation will analyze energy consumption for drying sugar infused fruits, demonstrating several drying scenarios. 1.) Energy used in a natural gas-heated conveyor dryer. 2.) Energy used with advanced control systems. 3.) Energy use with heat exchanging technology that recovers energy by preheating the make-up air. Energy consumption will be analyzed according to different operating parameters and will demonstrate how an energy recovery analysis can achieve a minimal energy reduction of 25-30%. The presentation will also introduce heat exchanger technologies, installation and operation.
 

LEARNING OBJECTIVES:

  1. Identify and explain the potential for heat recovery in an industrial conveyor dryer
  2. Evaluate dryer performance using an advanced control system
  3. Evaluate dryer performance with the use of heat exchanging technology
  4. Review the basic principles of drying and operations in an industrial processing line
