Abstract

The present application relates to the technical field of biological simulation experiment, and particularly relates to a ruminant in-vitro digestion system; comprising: a partitioned case platform and a bionic digestion reaction module, a dry heat field control module, a precise fluid and gas path distribution module, and a central control module; the present application constructs a dry infrared radiation coupling three-dimensional turbulent heat field, discards the water bath heating mode of high humidity corrosion, fundamentally eliminates the risk of electrochemical corrosion of the precise sensor interface, realizes the millisecond-level temperature control response superior to the water bath, and the system can autonomously execute the pH steady-state regulation of simulated saliva secretion and the pressure metabolic control of simulated belching, thereby constructing an intelligent experimental platform of highly reduced ruminant rumen physiological function in an absolute anaerobic closed system.
