    Dear Dr. Wohlbier,

    I´m a maintenance and project manager in an small grinding production plant in Spain , where we grind carob kernels to obtain flour. (it a quite similar process of grinding wheat) And most of our internal transport are pneumatical ones either kernels transport or powder fractions, in different ways: we have vacuum transport (ventilator or pumps) blowing process, and dense phase transport. My questions is: Do you know anybody or company which can perform and make an assesment of our pneumatical transports and give us a training in order to have the transport in optimal conditions and choose better options in future instalations?

    Many Thanks in advance.

    Angel Linuesa.

    Pneumatic Conveying in Carob flour milling

    Dear Mr. Wohlbier,
    Thank you very much for posting it.

    Our message for (the) Angel:

    Dear Angel,
    I have seen your post. I do not check very often this site, but i hope to not be late to you.
    Our company is specialized in technological designing for flour mills as for wheat, maize, rye, etc. and also for cereals silo as well as for finished products silo (flour and bran).
    In the flour milling technology there is a chapter about "Pneumatic Conveying in Flour Milling". You can find it almost in any modern flour milling book. At this chapter, all of them are recommending specific way for the design of the pneumatic conveying system, especially in the grinding section. The system used is a low phase multi-line vacuum pneumatic conveying system. For to design it there are some recommended mixing ratio for each type of product that will help you to find the air flow. Then, calculating the pressure drop in each line, the "heaviest" one will dictate the pressure required to the fan.
    Since i considered that engineering means more than this, i made my special research to find the limit of such a system and how to build a procedure for to design the system close to the physic limit, at the most energy efficient point.

    You can download some of the published papers at: http://tecnocereal.com/?page_id=42

    I'm at your disposition for further details and discussions. For more information on our company, please visit: www.tecnocereal.com
    We are available also for training discussions, if you will consider this option.

    Please kindly let me know if this topic is still interesting for you.
