Abstract: With the energy consumption and resource shortage, under the background of carbon peaking and carbon neutrality
goals, all walks of life in China are facing the pressure of carbon reduction. The carbon emission of the food industry accounts for
about 20% of the total carbon emissions, which is second only to the power energy industry and the transportation industry. There
is still huge room for emission reduction in food production and processing. Taking the processing of day lily as an example, this
paper focused on studying the energy consumption of different drying technology of day lily, such as air source heat pump drying
technology, air source heat pump plus infrared drying technology and constant temperature drying oven drying technology, and
analyzed the carbon emission of day lily processing process through the energy consumption data of each drying technology. The
results show that the drying efficiency of air source heat pump plus infrared drying technology is the highest, and the CO₂
emission of constant temperature drying oven drying technology is the lowest. Compared with the whole drying process, the
constant temperature drying oven drying technology is the best.
