product. The upper line represents the part-load efficiency curve for the
steamer when cooking frozen vegetables, while the lower curve represents the
steamer’s part-load efficiency when cooking more stubborn food products.
Steamer production rate is a function of the cook time. Appendix D contains a
synopsis of test data for each replicate of the cooking tests.

Light-load = single pan/load; Heavy-load = 6 pans/load.
Figure 3-3 illustrates the relationship between the Vortex steamer’s average
cooking-energy efficiency and the production rate for different types of food
product at different test scenarios. Heavy loads tend to exhibit higher
efficiencies due to better use of the available compartment space, as opposed
to light load single pan tests, where most of the space in the steamer
compartment is empty. Furthermore, Figure 3-3 shows that the frozen green
