Energy Efficiency Improvement and Cost Saving
Opportunities for the Fruit and Vegetable Processing
Industry
The U.S. fruit and vegetable processing industry—defined
in this Energy Guide as facilities engaged in
the canning, freezing, and drying or dehydrating
of fruits and vegetables—consumes over $800 million
worth of purchased fuels and electricity per year.
Energy efficiency improvement is an important
way to reduce these costs and to increase predictable
earnings, especially in times of high energy price
volatility. There are a variety of opportunities
available at individual plants in the U.S. fruit
and vegetable processing industry to reduce energy
consumption in a cost-effective manner. This Energy
Guide discusses energy efficiency practices and
energy-efficient technologies that can be implemented
at the component, process, facility, and organizational
levels.
A discussion of the trends, structure, and energy
consumption characteristics of the U.S. fruit
and vegetable processing industry is provided
along with a description of the major process
technologies used within the industry. Next, a
wide variety of energy efficiency measures applicable
to fruit and vegetable processing plants are described.
Many measure descriptions include expected savings
in energy and energy-related costs, based on case
study data from real-world applications in fruit
and vegetable processing facilities and related
industries worldwide. Typical measure payback
periods and references to further information
in the technical literature are also provided,
when available. Given the importance of water
in fruit and vegetable processing, a summary of
basic, proven measures for improving plant-level
water efficiency are also provided.
The information in this Energy Guide is intended
to help energy and plant managers in the U.S.
fruit and vegetable processing industry reduce
energy and water consumption in a cost-effective
manner while maintaining the quality of products
manufactured. Further research on the economics
of all measures—as well as on their applicability
to different production practices—is needed to
assess their cost effectiveness at individual
plants.
