Sizing Hoppers for Starch Application?

Sizing Hoppers for Starch Application?

Sizing Hoppers for Starch Application?

(OP)
Could somoene give some direction on how to size a hopper for a starch application, are there guidelines that I need to abide by.  Starch goes into a hopper down to mixer.

RE: Sizing Hoppers for Starch Application?

A general recommendation is to take into account the flow properties of your starch powder. The dimensions of the hopper for mass flow will depend on its cohesiveness which is a function of particle size, density, shape factor of the particles, moisture. Under its own weight aglomerates will be formed within the hopper with time and starch may stick on the wall of the hopper. If designed properly for worst case of flow function you will not need to use things like hammers, shakers, vibrators, which are only evidence that the hopper was not designed properly.There is a huge amount of information; search the concept of "Jenike and Johansson load cell" and you will understand the idea very soon.
