1. A multi-function device for intensive shrimp farming, comprising:
a support frame to support other parts of the device;
a water flow generator to create water flows in layers with a decreasing volumetric flow rate from a bottom to a surface of a shrimp pond, the water flow generator comprising an impeller, a motor driving the impeller through a drive shaft, and a body covering outside of said impeller, the body having a plate curved in a semicircle for catching water flows inside;
a feeder unit for providing industrial and functional food for shrimp, the feeder unit comprising a first container, a lid above the first container, a food sensor inside said first container which can sense an amount of food inside, a feed output below said first container, and a feed dosing motor that is placed on top of said feed output;
a substances-supplying unit for delivering substances into a shrimp pond environment, the substances-supplying unit comprising a second container, a crossbar on top of said second container, a stirring motor located in a middle of said crossbar, a pipe below said second container for leading a solution of substances to an outlet, and an automatic valve located on said pipe for controlling an amount of substance to be supplied;
a gas dissolving unit for diffusing oxygen into water, the gas dissolving unit comprising of at least: a porous ceramic tube; a stainless steel pipe comprising holes, the stainless steel pipe being placed inside said porous ceramic tube; a gap between said stainless steel pipe and the porous ceramic tube, wherein the gap is filled with sand; and stainless steel bars arranged around said porous ceramic tube; wherein said porous ceramic tube is sandwiched with rubber fasteners between two round stainless steel plates, said round stainless steel plates being secured together by bolts passing through said two round stainless steel plates and said bolts being fastened at one end to one of said round stainless steel plates by rivets;
a sensor for measuring water quality including dissolved oxygen concentration, pH, salinity, water temperature, turbidity, and measuring sunlight; and
a controller to operate the multi-function device, to connect and communicate with other components including the water flow generator, the feeder unit, the substances-supplying unit, the gas dissolving unit and the sensor via wiring and/or wireless communication, wherein said controller is operable to receive, from the sensor, system data information, then determine and adjust appropriate parameters, and transmit order information to the other components so as to enable the other components to operate according to defined parameters.
