Problems solved by technology

[0007] The above mentioned dialysis tubes are used as the device for biomimetic digestion of the gastrointestinal tract of animals, but the dialysis tubes are placed horizontally in an air bath shaker or a water bath shaker to simulate the digestion process, and it is easy to produce gas during the digestion process of feed materials in the dialysis tube. As a result, the rubber plug at the end of the biomimetic digestion tube falls off and the reaction solution leaks. Secondly, during the biomimetic digestion process, the digested sample is easy to stick to the dialysis bag, causing the dialysis bag to be blocked, which in turn affects the quality of the feed sample. Digestive effect

Abstract

A vertical type animal gastrointestinal tract bionic digestion device comprises a simulation digestive tract, a stirring rod, a motor and a magnetic transmission device. The simulation digestive tract comprises a vertical glass tube body and a dialysis tube body which is placed inside the vertical glass tube body. The stirring rod is installed in the dialysis tube body, and the top end of the stirring rod is detachably connected with the magnetic transmission device. The magnetic transmission device is installed above a silica gel plug at the top end of the simulation digestive tract and electrically connected with the motor. The motor is installed above the magnetic transmission device through a motor fixing base. The vertical type animal gastrointestinal tract bionic digestion device is simple in structure, convenient to use, good in accuracy and repeatability of digestion simulation and small in error, and bionic digestion reaction liquid leakage can be avoided.

Description

technical field [0001] The invention relates to equipment for bionic digestion experiments, in particular to a vertical bionic digestion device for the gastrointestinal tract of animals. Background technique [0002] In the modern aquaculture industry, objectively and accurately assessing the nutrient biological value of feed ingredients is the main decision-making basis for determining animal nutritional requirements and optimizing feed formulations. Since the 1960s, people have been trying to quickly evaluate the biological potency of feed nutrients by simulating the digestion of feed in the gastrointestinal tract of animals under in vitro conditions. [0003] In the prior art, triangular flasks or test tubes are usually used as bionic digestion devices for the gastrointestinal tract. When conducting simulated digestion experiments, first put a certain weight of feed into the triangular flask or test tube, then add simulated gastric juice or intestinal juice into the tria...
