Device and method for separating and recovering intestinal contents and extract thereof

A device for separating rand recovering intestinal contents, characterized in that the device comprising an impurity removal module and a target content collection module;

• wherein the impurity removal module is configured to remove impurity from the intestinal contents, comprise a stirring coarse filtration module and a fine filtration module;
• said stirring coarse filtration module having a liquid inlet and reflux port, said fine filtration module comprising a fine filtration cross-flow disc filter and a liquid storage box, and the penetrating fluid filtered by the fine filtration cross-flow disc filter is passed into the liquid storage box, and then into said target content collection module, a finely penetrating fluid is refluxed via a pipe through the reflux port back into the coarse filtration module, and mixed with the penetrating fluid under the coarse filtration, whereby forming a recycling loop;
• the target content collection module comprises a microporous membrane cross-flow filter, the microporous membrane has a spongy porous structure with a pore size of 0.01-20 μm, the microporous membrane has a porosity of 30% or more, and the microporous membrane is a hydrophilic film;
• the microporous membrane cross-flow filter has a disk-like structure, and is internally provided with a spiral flow channel;
• the ratio of an effective filtration area of a cross-flow disk to an overall area of the cross-flow disk is 0.3-0.9;
• said target content collection module is connected with the liquid storage box through the pipe, concentrated liquids of said target content collection module is refluxed back into said liquid storage box through the pipe, and mixed with penetrating liquids of the fine filtration module, whereby forming another recycling loop.
