Upgrade 1: Power optimisation, reducing power consumption by 500W with the same performance as the other shaker
Upgrade 2: Optimised body with the same performance, more compact than before
Upgrade 3: Optimisation of the powder control structure, allowing workers to add powder only once a day.
Upgrade 4: Optimised powder spreading, compatible with coarse and fine powder, solves the problems of blocked holes, slow powdering of coarse powder and too fast powdering of fine powder.
