Abstract: The disclosure discloses a dry garbage collection system and method with compressing and packing function, the system includes a central control display, a garbage putting bin, a compression and hot-melting bin, a packing bin, a forwarding bin, an air purification bin, a garbage can and a box; the garbage put in the system is compressed to form a cake shape and then performed a packing, and the garbage bags are hot-melted to shape, and vacuumized during packing process; the weight of the garbage before and after compression is compared to determine whether there is more wet garbage in the input dry garbage, so that an alarm can be sent out when the garbage classification is not standardized. The present disclosure realizes effectively compression and packing of garbage, significantly reduces the volume of garbage, prevents the garbage bin from overfilling, reduces subsequent garbage transfer times and transportation costs.
