The implementation process of the low-temperature continuous flash complete equipment in the embodiment 2 of the application is as follows: as the material is crushed, the material enters the crushing drum 51 from the feed pipe 515 and passes between the two crushing rolls 521. At this time, the first motor 5223 is started to drive the rotation shaft 5221 to rotate, and further drive the two crushing rollers 521 to rotate relatively, so as to crush the material passing through between the two crushing rollers 521. The material crushed by the crushing roller 521 passes through the cone 523 and falls into the crushing screen 531, and at this time, the second motor 5131 drives the fourth external gear 5132 to rotate, the fourth external gear 5132 drives the fifth external gear 5323 to rotate, and the fifth external gear 5323 drives the stirring shaft 532 to rotate, so as to drive the crushing blades 5321 to rotate. At the same time, the stirring shaft 532 drives the third external gear 5181 to rotate through the second external gear 5322, and the third external gear 5181 drives the internal gear 5312 to rotate, so as to drive the crushing screen 531 to rotate. At this time, the crushing blades 5321 and the crushing screen 531 reversely rotate, so that the crushing effect on the materials in the crushing screen 531 is improved.
