NOVELTY - Diffusion method of movable type fish luring bait material, is claimed. The fermentation pool is set with clapboard and mutually matched with a chute. The clapboard is set in fermentation pool. The fermentation pool is divided into multiple sub-fermentation pools. The bottom of the fermentation chamber is set with a support plate. A gas plate is fixed to the support plate. The gas plate is fixed around the seal plate at the top of bottom opening. The biogas produced in the fermentation pool is gathered in the sub-fermentation pool.    USE - The method is useful for diffusion of movable type fish luring bait material.    DETAILED DESCRIPTION - Diffusion method of movable type fish luring bait material, is claimed. The fermentation pool is set with clapboard and mutually matched with a chute. The clapboard is set in fermentation pool. The fermentation pool is divided into multiple sub-fermentation pools. The bottom of the fermentation chamber is set with a support plate. A gas plate is fixed to the support plate. The gas plate is fixed around the seal plate at the top of bottom opening. The biogas produced in the fermentation pool is gathered in the sub-fermentation pool. The gas plate is fixed inside the inner gas board. The slurry is introduced into the fermentation pool. The biogas slurry from the fermentation pool is introduced into the sub-fermentation pool. The biogas slurry is raised from the lowest point, drained and continuously fermented. The fermentation pool biogas slurry is introduced at room pressure. A gap is set between the upper and lower side of the gas board and the fermentation pool sidewall. The sub-fermentation pool is provided with a cross rod and vertical rod. At least one end of cross rod is connected to the vertical rod. The cross rod is set in the fermentation chamber of the sub-fermentation tank. A gap is set between the vertical rod located in fermentation chamber and the gas plate. The dredge pipe is provided to promote the fermentation of raw materials. The top of the gas plate is set with a windpipe for output of biogas. The biogas slurry pressure is set inside by drain pipe to fermentation pool. The biogas is introduced into the lure fish into the intake pipe. The intake pipe is connected with the spoiler tube. The spoiler tube is provided by multiple baffle orifice into the barrel. The barrel is driven by the flow of gas and making the bait into the water through the feed hole on the barrel.
