NOVELTY - An intelligent biomimetic rumen fermentor comprises a fermentation tank, an aerodynamic/hydrodynamic accessory system, and a function control system.    USE - The intelligent biomimetic rumen fermentor is useful for simulating rumen microecological environment of ruminant from the point of bionics; externally culturing anaerobic type strain colony; and controlling breeding of microorganism at an active and efficient state.    ADVANTAGE - According to advanced microcomputer technology and some aerodynamic and hydraulic automation control technologies, the whole fermentation process of intelligent biomimetic rumen fermentor can be controlled at a steady, high-efficiency and safe state; and intelligent, biomimetic, and industrial production of anaerobic type strain colony in a scale can be initiatively carried out.    DETAILED DESCRIPTION - An intelligent biomimetic rumen fermentor comprises a fermentation tank, an aerodynamic/hydrodynamic accessory system, and a function control system, where the fermentation tank is composed of a tank cover and a tank body, the tank body comprises an internal tank and an external tank; the internal tank is used for fermentation culture; bottom part of the internal tank is equipped with a disc side-hole direct injection pneumatic agitation device; the external tank is equipped with a heating device and an inlet and an outlet, and it is used for heating culturing material of the internal tank by water bath and for preheating a culture liquid transmission pipe extended into the internal tank and a gas pipe; outer side wall of the external tank is equipped with a bath water level pipe, a water temperature control meter and a leakage pipe for connected the internal tank and the external tank; the leakage pipe is communicated to an overflow bottle outside the tank; the point for cover of the overflow bottle is equipped with a full liquid annunciator; and the bath water level and temperature are regulated by the function control system; the tank cover is equipped with an automatic pressure regulating valve , a pressure gauge, a pH probe, a temperature gauge, and a sampling tube, where the pH probe, the temperature gauge, and the sampling tube are extended into culture liquid of internal tank; the culture liquid transmission pipe is extended to upper part of the internal tank through water bath region of the external tank; the gas pipe is extended to bottom part of the internal tank through water bath region of the external tank and opening of the internal tank and it is further connected to the disc side-hole direct injection pneumatic agitation device; various probes arranged on the fermentation tank are used for transmitting fermentation parameters to the function control system; in the aerodynamic accessory system, gas compressing pump and carbon dioxide (CO2) and nitrogen gas (N2) steel cylinders are communicated to the gas pipe within the fermentation tank; the aerodynamic accessory system is equipped with an expiration annunciator; the gas compressing pump is connected to a circulation gas condensing bottle and a moisture separator for protecting the gas compressing pump; opening of the condensing bottle is equipped with an oxidizing valve for aerobic oxidation reaction; all the gas pipes are equipped with several solenoid valves and adjustable flowmeters; the aerodynamic accessory system is controlled by the function control system for intelligently regulating flow direction of gas and for controlling flow rate, thereby to carry out control of gas flow within the fermentation tank; and gas within the tank is connected to the gas compressing pump through a fermentation gas returning pipe so as to achieve internal circulation of gas and maintain anaerobic state; the hydrodynamic accessory system comprises lye, a culturing liquid storing tank, an automatic liquid supplying bottle and a liquid supplying pipe, where the lye and the culturing liquid storing tank are connected to one end of the corresponding automatic liquid supplying bottle, respectively; a lye transmission pipe connected another end of lye automatic liquid supplying bottle is extended to upper part of internal tank of the fermentation tank so as to form a lye dropper; a culturing liquid transmission pipe connected another end of culturing liquid automatic liquid supplying bottle is extended to upper part of internal tank through water bath region of the external tank so as to form a culturing liquid dropper; all the liquid transmission pipes are equipped with several solenoid valves and adjustable flowmeters; the hydrodynamic accessory system is controlled by the function control system for intelligently regulating flow direction of liquid and for controlling flow rate, thereby to carry out control of material within the fermentation tank; the function control system is connected to the fermentation tank and to the aerodynamic/hydrodynamic accessory system, and used for receiving the information of fermentation parameter, and further used for intelligently controlling operation of the whole fermentation system through a microcomputer controller; and the function control system comprises a temperature, pH and working time controller, an alarm buzzer, and an automatic control for transmission of liquid and gas.
