How to space pedestals in your grain store  

STORAGE DEPTH MAXIMUM SPACING 
2.5-3.5m Storage depth plus 100%
3.6-5.0m Storage depth plus 75%
5.1m and above Storage depth plus 50%

 Storage depths of 5.5m and above should be a matter for individual appraisal.

 

Sucking the air or blowing, that is the question!

The great news is our VBW fans will do either with no additional purchase required to facilitate this.  The AHDB recommend blowing the air into the pedestal or duct.  Anecdotally we have found that our customers favour sucking the air out of the crop for the following reasons:

  • Grain quality can be monitored by the quality of the air leaving the fan.
  • Condensation is less likely to cause surface crusting of the crop.

Whatever you favour do not attempt to do both as this will result in sections of grain being under ventilated.  Pick an airflow direction and allow the cooling front to move fully from surface to duct or vice versa.

Polycool is custom manufactured for the purpose of crop cooling. It is a common misconception that they are simply twin wall drainage pipe.  Polycool is manufactured using food grade, virgin polymer (added strength) and larger and longer slots to allow the air to flow freely through the crop. The ribbed construction of the Polycool system not only adds strength, it stops the crop from blocking the perforations and allows equal airflow throughout the base of the pedestal. Internally you will be able to see that perforations are considerably larger than those found in 450mm black land drainage pipe.
