What are the drying methods of hydroxypropyl methylcellulose?
The hydroxypropyl methyl cellulose must be dried under the condition of production. If this production process is not carried out, it will not be able to guarantee the transportation and resist the corrosion of the poor external environment.
According to the investigation, the hydroxypropyl methyl cellulose enters the air dryer through the belt conveyor and the heated natural vapor. The two are sufficiently mixed. Due to the large area of heat and mass exchange, it takes a very short time. Inside to ensure the purpose of evaporation and drying. When using this kind of method, the carboxymethyl carboxymethyl cellulose can continuously enter the drying tube under the pulse air dryer according to the feeder.
In the drying tube, the hydroxypropyl methyl cellulose can be blown away by high-speed air and move upward, so that the raw material and the air flow are in sufficient contact, and the water can be quickly evaporated. According to the drying tube, it is collected by the dust collector, and then enters the pulse air dryer for drying again, which effectively increases the drying time of the raw materials.
After hydroxypropyl methyl cellulose is dried, the fracture toughness of some products is further improved, and its characteristics are further improved, so that it will greatly increase your economic benefits.
