Citrus packhouses are vital to producing citrus fruit that is marketable, healthy, and ready for transport. The packing process involves many different activities, from washing, de-greening, and treating fruit, to sorting, grading, labelling, wrapping, and packing. This means that there are a lot of people and machinery involved in the process, and there are many places where things can go wrong. Understanding the components, personnel, equipment, and machinery involved throughout the packing process is the first and most important step to owning, supervising, managing, or working in a packhouse efficiently and effectively.
