Double-blade fermentation tank

The utility model relates to a double-blade fermentation tank which comprises a shell, an insulating layer, a resistance wire, a container, a top cover, a reflecting sleeve, a temperature sensor and a controller. The double-blade fermentation tank further comprises an inner and outer blade bidirectional stirrer; the inner and outer blade bidirectional stirrer, the resistance wire and the temperature sensor are connected with the controller through a signal line. After the technical scheme is adopted, and through the structural design of the inner and outer blade bidirectional stirrer, the stirring efficiency is improved; through the frame type design of an outer blade, the outer blade is closer to the container, so that the problem that a traditional stirring blade cannot stir solution at the corner part of the container is solved, therefore, the stirring is more uniform; with the adoption of an infrared material and a temperature uniformity control system, the brewing quality of fruit wine is improved, so th
