The rumen is the natural fermenter with the strongest ability to degrade fiber materials known so far. The fermentation in the rumen is not only the physical action of the peristalsis and squeezing of the rumen wall, but also the result of microbial action. In order to detect and compare the microbial nutrition and metabolism in the rumen, in vitro fermentation tests of ruminant live rumen fluid are usually used; the degradation rate and gas production are important means to evaluate the nutritional value of feed and the efficiency of nutritional regulation. This experiment is to collect fresh rumen fluid and put it into a fermentation bottle, add the corresponding feed to be tested, and study the digestion characteristics of the feed. After the feed is fermented and degraded in the rumen fluid to produce gas, the gas needs to be collected for analysis, and the fermented feed is taken out and dried to measure the quality, and the degradation rate is compared with the original quality.

When conducting the experiment, the rumen fluid and the feed to be tested are manually placed in the fermentation tank, and the fermentation tank is used to simulate the environment inside the rumen for the experiment. However, the existing fermentation tank is very small, so when conducting the experiment, it is necessary to manually shake it continuously so that the rumen fluid, the feed to be tested, and the gas produced by the fermentation are all concentrated in the fermentation tank. In the case of shaking, it is not convenient for humans to collect the generated gas, which will affect the results of the experiment.
[0004] Therefore, it is necessary to design a device to detect the in vitro fermentation and degradation gas production of rumen. Utility Model Content

DETAILED DESCRIPTION
[0020] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.
[0021] Example: Detection of rumen in vitro fermentation degradation gas production device, please see Figures 1 to 5 , including a fermentation tank 1, a sealing cover 2, a sealing ring 201, an air inlet pipe 3, an air outlet pipe 4, a one-way valve 5, a motor 6, a stirring rod 7, a scraper 8, a heating block 9, a feeding pipe 10, a valve 11, a timer 12 and a scale 13. The top of the fermentation tank 1 is equipped with a sealing cover 2, and the bottom of the sealing cover 2 is covered with a sealing ring 201, which can ensure the sealing between the fermentation tank 1 and the sealing cover 2. The top left side of the sealing cover 2 is connected with the air inlet pipe 3, and the top right side of the sealing cover 2 is connected with the air outlet pipe 4. The air outlet pipe 4 and the inner upper part of the air inlet pipe 3 are both equipped with A one-way valve 5 can prevent gas backflow. A motor 6 is installed at the center of the top of the sealing cover 2. The output shaft of the motor 6 is connected to a stirring rod 7 through a coupling. The stirring rod 7 is located inside the fermenter 1, and a scraper 8 is connected to the bottom of the stirring rod 7. A heating block 9 is installed at the inner bottom of the fermenter 1. A feeding pipe 10 is connected to the upper rear side of the fermenter 1 in a through-type manner. A valve 11 is rotatably connected to the inner upper part of the feeding pipe 10. A timer 12 is installed on the lower front side of the fermenter 1. A scale 13 is provided on the outside of the fermenter 1 to facilitate checking the amount of feed added to be tested.
[0022] When it is necessary to use the in vitro fermentation degradation and gas production device for detecting rumen to conduct an in vitro fermentation test of rumen liquid in living ruminants, first place the in vitro fermentation degradation and gas production device for detecting rumen at a designated work location, then open the sealing cover 2 upwards, and add a proper amount of feed to be tested into the fermenter 1. After the addition is completed, install the sealing cover 2 back onto the fermenter 1. According to the design of the sealing ring 201, the sealing performance of the fermenter 1 can be ensured to prevent gas leakage. Then open the valve 11, add a proper amount of rumen liquid from the feeding pipe 10. After the addition is completed, close the valve 11 to prevent the gas produced by the fermentation from leaking from the feeding pipe 10. Then connect the external hose to the air inlet pipe 3, inject carbon dioxide and nitrogen through the air inlet pipe 3, so that the fermenter 1 is in an anaerobic environment. Thereby, the fermentation test conditions outside the rumen liquid of the living ruminant are met. According to the design of the one-way valve 5, it is possible to prevent gas leakage from the air inlet pipe 3 and the air outlet pipe 4, thereby ensuring the airtightness of the fermenter 1. After the injection is completed, the heating block 9 is started to perform heating work to provide heat to the inside of the fermenter 1, thereby promoting the fermentation outside the rumen liquid of the living ruminant. The motor 6 is started to provide power to drive the stirring rod 7 and the scraper 8 to rotate, which can mix the feed to be tested in the fermenter 1 with carbon dioxide and nitrogen, so that the rumen liquid, the feed to be tested, and the gas produced by fermentation are all concentrated in the fermenter 1. When the scraper 8 rotates, it can scrape the feed at the bottom of the fermenter 1, thereby preventing the feed from sticking to the bottom of the fermenter 1, so as to facilitate the fermentation outside the rumen liquid of the living ruminant. In order to make the test results more accurate, people can conduct long-term fermentation tests outside the rumen liquid of living ruminants. An appropriate amount of artificial saliva (buffer) can be added from the inlet of the feeding tube 10. After adding, use the timer 12 to record the test time. When the fermentation reaches the specified time, the motor can be turned off and the heating block 9 can be turned off. Then connect the external hose to the outlet pipe 4 to collect the gas produced by the fermentation. After collecting, open the sealing cover 2, take out the tested feed, and then analyze the collected gas. After the fermented feed is taken out, dry it to measure the quality, and compare it with the original quality to obtain the degradation rate. The above operations can complete the test of fermentation outside the rumen liquid of living ruminants.
