Through several stages, namely the hopper, barrel, screw lip, cooling tub, dryer fan, cutting machine, filter 2, the calculation results of the heat transfer in a barrel with a temperature of 240-268 ℃ can be concluded, the heat rate in the barrel is 28100.8 h. / s and the amount of heat in the barrel of 218700 j. so as to produce a good and appropriate plastic seed product.
