The invention discloses a
natural rubber drying process and device with a pretreatment function, and belongs to the technical field of rubber
drying. Granulated
natural rubber particles are conveyed to a rubber vehicle by using water containing an anti-sticking agent, the rubber loaded into the vehicle is preheated and then enters a high-temperature and high-
humidity environment of a closed section, and a water migration inner channel is opened; and then entering a continuous
drying section for partitioned variable-temperature-
humidity drying, and finally getting out of a vehicle after reaching the standard. The device comprises a tunnel type hot
air drying cabinet provided with a plurality of glue vehicle parking spaces, the
parking space at the foremost end of a tunnel is a preheating section, a sealing section is arranged behind the preheating section, all the parking spaces behind the preheating section are continuous drying sections, an upper air
flue and a lower air
flue are arranged on the upper portions and the lower portions of the parking spaces in the tunnel respectively, and partitions are arranged on the air flues every part of the parking spaces. An air inlet and an air outlet are alternately formed in the air duct between every two adjacent partitions; bonding among rubber particles during high-temperature drying can be overcome, the high-temperature tolerance of rubber is improved, the drying rate in the
speed reduction stage is increased, generation points are reduced, and the energy
utilization rate of a drying
system is increased.
