The invention relates to an automatic rice dumpling material distribution system and method, and aims at solving the problem that the rice dumpling material feeding conveying efficiency is low, the rice dumpling materials are easy to spill during the putting and accurate material distribution cannot be carried out for the rice dumplings such as meat rice dumplings needing to adding ingredients during the rice dumpling production in the prior art. The system comprises a control platform, a feeding conveying device, a distribution device and a material cup conveying device, wherein the distribution device comprises a first combined balance, a second combined balance, a first rice dumpling material putting mechanism and a second rice dumpling material putting mechanism; the first rice dumpling material putting mechanism and the second rice dumpling material putting mechanism are respectively connected with the first combined balance and the second combined balance; the control platform is connected with each of the two combined balances; the conveying devices are connected onto the two combined balances. The system and method provided by the invention have the advantages that rice dumpling material putting is carried out for twice, so that the weight of the rice dumpling materials is ensured and the problem of short weight of rice dumplings caused by rice dumpling material spill or less putting is avoided; the rice dumpling materials after the ingredient putting can be weighed so as to calculate the weight of the rice dumpling materials put for the second time, so that the weight distribution of the rice dumpling materials of multi-ingredient rice dumplings such as meat rice dumplings, yolk rice dumplings and the like can be more accurate.
