The invention discloses a processing flow of coconut flesh production by mechanical line processing. The processing flow solves the difficulties of mechanical shelling, peeling and processing of coconuts. A technical scheme provided by the invention comprises the following steps: 1, sieving out coconuts of different sizes by using a grading-sieving machine; 2, pressing the sieved coconuts by usinga pressing machine so as to loosen junctions between shells and flesh of the coconuts; 3, cracking the shells of the coconuts by using a cracking machine so as to crack the shells into multiple pieces; 4, punching the shells of the coconuts by using a punch or a punch for a press machine or a press machine so as to punch the shells into multiple parts; 5, obtaining some coconut flesh separated from the shells during the punching process, and performing manual operation so as to separate the remaining coconut flesh from the shells; 6, performing manual operation so as to sort and classify thecoconut flesh and the shells, and removing deteriorated coconut flesh; and 7, sending the coconut flesh into a cutting machine so as to separate the coconut flesh from black peel by performing cutting.
