The invention relates to the technical field of a papermaking device, and specifically discloses a pulping system of eco-friendly food-grade brown bamboo pulp. The system comprises, according to the conveying route of a bamboo material, a pretreatment apparatus, a conveying apparatus, a boiling apparatus, a blowing apparatus, a pulp washing apparatus and a spin-drying apparatus in sequence. The conveying apparatus includes a housing and a rotation mechanism. The rotation mechanism is fixed in the housing and comprises a driving chain wheel, drag chains and scraper plate assemblies used for conveying bamboo sheets, wherein the drag chains are two parallel sets and are engaged with the driving chain wheel, and the scraper plate assemblies are arranged between the drag chains in parallel. The boiling apparatus includes a boiling pot and a boiling liquid complementor, wherein the feed port of the boiling pot is connected to a discharge port of the conveying apparatus. The blowing apparatus includes a blowing pot and secondary blowing transverse tubes, wherein the blowing pot is connected to the boiling pot through a pipe and is connected to the pulp washing apparatus through the secondary blowing transverse tubes.
