The invention discloses a front drying system used for a multi-cylinder long mesh paper machine, and belongs to the field of accessories of paper making equipment. The total number of drying cylinders of the front drying system is increased by 10%-50% than that of drying cylinders of a front drying portion of a traditional front drying system with the same width and the same vehicle speed. A reinforced drying device can be arranged at an outlet of a front drying portion; high padding paper pulp can be made into paper meeting standard requirements; the front drying system has the advantages that drying time is long, the drying effect is good, paper can be sufficiently dried and dehydrated, follow-up glue applying of paper is facilitated, and quality of finished product paper is high; problems of the traditional front drying system are solved; the front drying system is one of the important procedures in successful development of the multi-cylinder long mesh paper machine used for production of high padding paper pulp.
