The invention discloses an economical jute processing system. The economical jute processing system comprises a jute carrier, a feeding-discharge station, a carding device and a conveying device. A jute leather clamping mechanism and a tensioning mechanism are arranged on the jute carrier. The conveying device comprises a closed conveying track. The jute carrier is arranged on the conveying track, on which multiple joints are arranged. The feeding-discharge station and the carding device are arranged on the joints. The economical jute processing system has following beneficial effects: a simple processing device capable of replacing manual work is replaced by the economical jute processing system; parts and an assembly structure are designed easily; usage and maintenance are simple; purchase and usage cost are far lower than that of a full-automatic hemp fiber processing machine; machining efficiency and machining quality are obvious superior than those of manual work; and higher cost performance is obtained.
