“…The conventional drying literature however has slightly different meanings for the terms "energy or thermal efficiency" as well as "drying efficiency". Thermal efficiency is defined in the traditional drying literature (Kudra, 2004;Menshutina et al, 2004;Atuonwu et al, 2012) as the ratio of latent heat delivered (evaluated at feed temperature) to the total thermal energy input. Comparing this with the equation for the same term, in microwave drying literature (equation 4), it is observed that the sensible heat term Qsens is missing, from the conventional drying expression.…”

The enormous magnitude and variety of microwave applications in household, commercial and industrial food processing creates a strong motivation for improving the energy efficiency and hence, sustainability of the process. This review critically assesses key energy issues associated with microwave food processing, focusing on previous energy performance studies, energy performance metrics, standards and regulations. Factors affecting energy-efficiency are categorised into source, load and source-load matching factors. This highlights the need for highly-flexible and controllable power sources capable of receiving real-time feedback on load properties, and effecting rapid control actions to minimise reflections, heating non-uniformities and other imperfections that lead to energy losses. A case is made for the use of solid-state amplifiers as alternatives to conventional power sources, magnetrons. By a full-scale techno-economic analysis, including energy aspects, it is shown that the use of solid-state amplifiers as replacements to magnetrons is promising, not only from an energy and overall technical perspective, but also in terms of economics.

“…As drying is an energy-intensive process, accounting for about 10-25% of the national industrial energy of the developed world [9,10], it is very important that drying processes are energy-efficient. It is therefore not surprising that energy efficiency has over the years been a key driver of research and development in drying technology [10].…”

The energy performance and carbon footprint associated with the fluidized bed drying of petals of Echium amoenum Fisch. and C.A. Mey are experimentally evaluated at three temperatures (40,50,60°C) and air velocities (0.50,0.75,1.00m/s). The maximum and minimum specific energy consumption are observed to occur at 40°C and 1ms-1 (79.18MJ/kg) and 60°C and 0.5m/s (22.60MJ/kg), respectively. The greenhouse gas emission is in the range, 0.10-8.40kgCO2eq, varying with drying conditions in the same manner as energy consumption, with natural gas-fired systems performing better than oil-fired systems. High-temperature, low-air velocity drying is thus, favourable for energy-efficient and sustainable fluidized bed drying of the petals.Keywords: fluidized bed dryer; greenhouse gas; specific energy consumption; Iran.
