  1. Looks great BUT...… you are now using instrumentation and PLC control. And the BUT part is that these are not Ex / Atex certified within your system when you do this. So how are you getting around this. Personally I love the automation part. Would love to know the answer to the above.
  2. +1 for that. Generally when I design, I allow for +20% at least FOS. The last thing that I ever want is where customers come back to me and say whatever ........ In my kegging plant which we design and build and further which is highly automated and technically advanced ..... the bloody plant just goes on and on and on and at some point I need to tell the customer that I need to break the plant because I need to earn some call out money. But more importantly so, I supply the plant up into Africa and travelling out there is expensive and so it needs to be bullet proof.
  3. We supply cullinary steam filters into the market and are supplied at 1 micron. To be considered cullinary, the filter cartridge must be max 3 microns and less.
  4. My system is based on the Click PLC and the C-More HMI. Reason ....... because surplus stock and lying around in my stores. I love the Direct logic PLC's so will always recommend it. HMI's, no would presently go for Weintek.
  5. We have just built a high end and extremely efficient unit which will go for performance testing later this month. The major characteristics of our unit are high flow, very high surface area for heat exchage as well as being designed for grain in mash chilling. Here's a pitcure straight out of production and prior to clean up and final fitting of attachments and controls.
  6. BUT..... you then do not have any safety interlocks and then this is super dangerous. I have programmed interlocks and in addition..... reduced power (my heating controller is 4-20mA), pressure monitoring, level monitoring, temperature monitoring with control and cooling water valve control.
  7. Only effective way to do this is by installing a PLC and with complete automation. Expensive because apart from all automation, process valves etc. , you now have to consider all Ex requirements as well. Here's a cropped part of my HMI heat up screen image
  8. Interesting the blades and their angled direction where the product is lifted upwards. The majority of blades from what I see appear to force the product downwards
  9. Silk you mention various micron sizes. What efficiency are these.... Nominal ?? <99%
  10. Word of caution, that air is not 100% oil free. Rather add in coalescing filters to accompay the installation. This way you have a lot more security built in.
  11. True BUT, when one is no longer a spring chicken this becomes somewhat more challenging. !!
  12. Looks great. I am surprised however that you have not used baffles in the stack so as to get better / more efficient cooling.
  13. +1, Yes Paul and others are right. Everyone needs to look out for each other.
