A process for the continuous coagulation and drying of rubber latex includes feeding the latex onto an endless conveyor belt which feeds the latex through a coagulator. A combination of microwave energy and hot air raises the temperature of the latex causing it to coagulate in a coagulation time of less than five minutes. The coagulated rubber from the coagulator is fed into a conveyor belt of a stretch unit which stretches the rubber by increasing its speed of travel. The stretched rubber is then conveyed onto the upper belt of a drying unit. The drying rubber is passed from the upper belt onto an intermediate belt and then on to a lower belt before leaving the drying unit. A combination of microwave energy and hot air in the drying unit is used to dry the rubber to a moisture content of less than 1.5%.
A process for continuous coagulation and drying of rubber latex, comprising passing a stream of the latex through a coagulator to form a coagulated rubber stream, introducing the coagulated rubber stream from the coagulator into a dryer downstream of the coagulator, and passing the coagulated rubber stream through the dryer to dry the rubber, in which the latex stream in the coagulator is heated by a combination of microwave energy and hot air.
An apparatus for continuous coagulation and drying of rubber latex, comprising a coagulator, a first feeder to pass a stream of latex through the coagulator to form coagulated rubber, a primary heater operable to provide a combination of microwave energy and hot air to coagulated the latex stream passing through the coagulator, a dryer to receive the coagulated rubber stream from the coagulator, a second feeder to pass the coagulated latex stream through the dryer, and a secondary heater to dry the coagulated rubber passing through the dryer.
In a process for the continuous coagulation and drying of rubber latex, the improvement comprising heating a latex stream in a coagulator by a combination of electromagnetic and heated gas.
In an apparatus for the continuous coagulation and drying of rubber latex, the improvement comprising heating apparatus first to coagulate a latex stream with a combination of electromagnetic energy and heated gas and second to dry the coagulated latex stream.
