The invention relates to a device for continuously concentrating gelatin by membrane technology. The outlet of a rolled membrane module of the device is communicated with a first connector of a four-way joint; a second connector and a third connector of the four-way joint are respectively connected with an original gelatin tank and a thick gelatin tank; the inlet of the rolled membrane module is communicated with an outlet of a circulating pump; a sorption pump and a filter are successively connected in series between the original gelatin tank and the inlet of the circulating pump; a first stop valve is in series connection with a pipe between the sorption pump and the filter; a second stop valve is in series connection with a pipe between the original gelatin tank and the outlet of the rolled membrane module; a first butterfly valve is in series connection with a pipe between the outlet of the rolled membrane module and the thick gelatin tank; a second butterfly valve is connected inparallel between the inle
