A solid-liquid-gas three-phase split rumen simulation continuous fermentation system and method

Abstract

The invention provides a solid-liquid-gas three phase flow-dividing rumen imitation continuous fermentation system, which is characterized by comprising a fermentation tank body (a), a stirring device (b), a liquid discharging valve (c), a solid discharging device (d), an injection pump (e), a computer (f) and a CH4 and CO2 detector (j). By using the fermentation system, the solid-phase, liquid-phase and gas-phase products produced by fermentation in the fermentation tank can be separated with high efficiency and delivered to the solid discharging device, the liquid discharging valve and the CH4 and CO2 detector respectively. The products in three phases discharged from reaction can be measured accurately by corresponding measuring means, so that deep study on fermentation reaction effectof different kinds of feed can be facilitated. Meanwhile, as an injection pump for supplying buffer solution into the fermentation tank constantly is designed, the drawback that a static fermentationdevice cannot realize continuous fermentation is overcome. In addition, the whole control process of the system can be implemented by high-automation control of a computer.

Description

technical field [0001] The invention relates to the technical field of ruminant nutrition research, in particular to a continuous fermentation system for simulating rumen fermentation of ruminants such as cattle, sheep, and solid phase, liquid phase, and gas phase with split discharge and a fermentation method thereof. Background technique [0002] The digestion of the rumen of ruminants mainly depends on the decomposition and fermentation of various components in the diet by various microorganisms and protozoa living in the rumen. Studies have shown that about 40% to 80% of the dry matter in the feed is in the rumen Digestion, 80% of which is carbohydrates; about 60% to 80% of organic matter, 10% to 100% of crude fat are also digested in the rumen, and 23% to 87% of the total energy is also digested in the rumen. In particular, about 90% of the crude fiber in the feed is fermented in the rumen, only about 10% is digested in the large intestine, and little or no hemicellulos...

Problems solved by technology

Moreover, the artificial rumen device needs to work continuously for a long time. During the whole process, it needs real-time rehydration, real-time collection of gas generated during fermentation, continuous stirring, regular addition of feed, and collection of liquid and solid samples. Therefore, the work is heavy and requires a lot of manpower.
