Drying Performance
How fast, typically, can I dry my grain on a drive-on- floor?Answer:
- This depends on several factors including (1) the crop type, (2) the initial moisture content (it is much quicker to dry from 20 to 17 than 17 to 14% moisture content (MC) due to it being more difficult to get the moisture out of drier grain), (3) the crop depth, (4) the ambient temperature & relative humidity.
- A general rule of thumb is ½% per 24 hours ventilating with the correct airflow at the correct humidity.
- Ambient temperature, however, is an influencing factor, i.e. the cooler the air the lower its “moisture carrying capacity”, so that air at 5 deg C and at 65% RH will have one quarter of the drying effect of air at 20 deg C at 65% RH! Therefore it pays to get the crop dry before the ambient temperature falls in the autumn.
- The introduction of a gas heater once moisture content is below 18% will increase the potential drying rate by a factor of three.
- Without heat the ambient RH may be suitable for drying for only 8 hrs a day whereas with heat (or dehumidification) the RH can be maintained at the required level 24hrs/day.
