The invention discloses a lemon slice production system capable of effectively saving resources. The system is provided with a control system, a power supply system and lemon dryslice production equipment. The control system is respectively connected to the power supply system and the lemon dryslice production equipment. a washing device, a first sterilization chamber, a first cleaning chamber, an excision table, a second sterilization chamber, a second cleaning chamber, a slicing chamber, a freezing chamber and a vacuum drying chamber, which are successively connected, are arranged inside the lemon dryslice production equipment. The power supply system comprises a solar power supply circuit, a wind energy power supply circuit, an inverter circuit, an AC power supply circuit and a power supply control circuit. The AC power supply circuit is connected to the lemon dryslice production equipment. During lemon dryslice production processing, the control system and the lemon dryslice production equipment can be powered by the power generation mode of solar energy and wind energy in renewable energy sources. Thus, loss of non-renewable energy resources is reduced, more non-renewable resources are left for descendants, and the system has effects of saving energy and protecting the environment.
