The invention discloses an evaporation device and system. The evaporation device comprises a first heating part, a thermal conduction part and a jet part, wherein the thermal conduction part includes a first thermal conduction part and a second thermal conduction part, the second thermal conduction part surrounds the first thermal conduction part, a certain distance exists between the first thermal conduction part and the second thermal conduction part, the space between the first thermal conduction part and the second thermal conduction part can be used for placing evaporation materials, and the thermal conduction part is used for transmitting heat dissipated by the first heating part to the evaporation materials so as to sublimate the evaporation materials; the jet part is used for jetting the sublimated evaporation materials. The evaporation system comprises the evaporation device, a monitoring device, an PLC control device and a temperature control device, wherein the monitoring device is used for monitoring the jetting speed of the evaporation materials; the PLC control device communicates with the monitoring device and used for receiving the jetting speed acquired by the monitoring device, judging jetting speed rate, and transmitting an instruction to the temperature control device so as to adjust the heating temperature of the first heating part according to the judging results.
