The invention provides an energy-saving drying method capable of improving qualities of dried abalones. The energy-saving drying method capable of improving the qualities of the dried abalones comprises the following steps: selecting live abalones; temporarily feeding the selected abalones; shelling the abalones and taking the meat; carrying out high-pressure salting treatment on the abalone meat; carrying out drying by performing radio-frequency drying technology, infra-red drying technology and solar-energy-aided heat pump drying technology in subsection application; moreover, constant-temperature constant-humidity water balancing treatments are performed in supplementation for two times so as to effectively reduce surface shrinking and hardening of the abalone meat; thus, the sensory effects and the re-watering properties of the dried abalones are improved so as to facilitate formation of soft-centre abalones. By adopting the high-pressure salting treatment, the salting treatment process is accelerated by the high pressure, and the synergistic effects of sodium salts and acidic electrolysed water are utilized so as to effectively kill the micro-organisms in the abalone meat; moreover, the effects of the high pressure and the sodium salts are capable of modifying myoglobulin dissolution so as to improve the gel properties of the abalone meat, and further improve the texture characteristics of the re-watered abalone meat. The energy-saving drying method capable of improving the qualities of the dried abalones is simple in operation processes; moreover, novel high-performance green heat sources are selected, so that the energy can be saved by 30% or more. Thus, the energy-saving drying method capable of improving the qualities of the dried abalones facilitates realization of continuous automated clean and energy-saving production.
