NOVELTY - A fish residual processing system comprises a fish residual collecting system and a fish residual processing system.    USE - The system is useful for effectively processing water body and for effectively collecting fish residual generated in the aquiculture.    ADVANTAGE - The system analyzes the aero discharge of the aquiculture waste, where the aquiculture industry can increase the income while reducing the consumption and saving energy.    DETAILED DESCRIPTION - A fish residual processing system comprises a fish residual collecting system and a fish residual processing system; the fish residual collecting system is mainly the mechanical filtering system which carries out the physical back washing filter to the cultivation water body using the rotary belt-shaped filter; the mechanical filtering system is composed of a motor, a filter screen, a filter frequency controller, a dehydrator frequency controller, a water level probe, a washing valve, a pressure probe, a high pressure spraying head and a pressure tank; the filter screen of the rotary belt-shaped filter filters the deposit particle in the filtering water and sends it to the backing washing device with the driving of the motor; it uses the high pressure spraying head to remove the deposit seed on the filter screen; the rotating speed of the motor increase along with the raising of the water level and regulates the frequency of the motor power source through sending the signal to for the filter frequency controller and the dehydrator frequency controller by the water level probe so as to change the rotating speed of the motor; the pressure probe and the pressure tank provide the water pressure to the high pressure spraying head; the upper end part of the filter screen is connected to the conveying pipeline; and the suspended substance drops into the fish residual suspended substance. It enters into the dehydrator to be transport to the fish residual collector after being dehydrated and compressed via the automatic washing device; the fish residual processing system is composed of a mixing tank, a fermentation tank and a drying device; the mixing tank, fermentation tank and the drying device are connected by the conveying device; it takes the fish residual as the material. The water material adding the cultivating edible fungus with a certain proportion is mixed with the chaff in the mixing tank. The mixing device is used to mix it; the components enter into the drying device to be dried with mild temperature after the fermentation and well-rotted processes; and then it is packed into the finished products.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the fish residual processing system.
