Fermentation device, planting system, and fermentation method

A fermentation device configured to mix liquid raw material and solid raw material and gradually ferment the liquid raw material and the solid raw material into a liquid fermentation product, comprising:

• a fermenter;
• wherein the fermenter comprises a tank, augers, and a motor;
• wherein the tank is horizontally arranged;
• a first end of the tank is connected with a material feeding port;
• a second end of the tank is connected with a material discharging port;
• a height of the material discharging port is not less than a height of the tank;
• the liquid raw material and the solid raw material are added into the tank from the material feeding port;
• wherein the augers are horizontally arranged in the tank;
• each of the augers comprises a central shaft and a blade;
• an inner edge of each blade is connected with a corresponding central shaft;
• a gap is defined between an outer edge of each blade and inner walls of the tank, wherein a first end of each central shaft of each of the augers is fixed, and a second end of each central shaft is a free end;
• the free end of each central shaft is capable of fluttering in the tank by the liquid raw material and the solid raw material in the tank, each blade flutters to rub the inner walls of the tank, and a portion of the viscous slag material on the inner walls of the tank is rubbed to be fermented;
• and
• wherein the motor is connected with the augers and drives the augers to rotate in a first direction or a second direction;
• when the augers rotate in the first direction, the liquid raw material and the solid raw material move from the material feeding port towards the material discharging port;
• when the augers rotate in the second direction, the liquid raw material and the solid raw material move from the material discharging port towards the material feeding port.
