Trouble-Dry Aeration Spears and Fans

DSC01452 - Copy

Trouble-Dry hot spot aeration spears and fans have an important part to play in a professional crop storage system. For small quantities of grain, urgent spot drying, unexpected insect infestations and many more uses – Martin Lishman Trouble-Dry Aeration Spears and Fans are the ideal tool for the job. Simply screw the spear into the affected area and suck the heat out.

Choosing the right Trouble-Dry aeration spear for your store

How fast do you want to cool your crop?

The Trouble-Dry Standard aeration spear is cheaper but the fan is smaller so is slower to cool the grain, covers a smaller area and will need to be moved more frequently.

The Trouble-Dry Extra aeration spear has a stronger fan so cools more grain faster and needs to be moved less often.

Why is it so important to cool grain quickly with a hot spot aeration spear?

  • Hot grain quickly deteriorates
  • Cool grain keeps safely, with less chance of insect infestation
  • Unventilated grain may seem OK, but it can heat up without warning
  • Trouble-Dry aeration spears and fans cure the problem before it gets serious

Advantages and Benefits of Martin Lishman hot spot aeration spears and fans

  • Choice of aeration spears – to deal with all hot spot problems
  • Strong, extra-long single piece handle – easier to screw the spear in to hot grain
  • Choice of fans – to provide faster cooling of more grain and spot drying

Are all hot spot aeration spears and fans
the same?

No they aren’t. Alternative aeration spears may have handles that can bend or are too short to give enough leverage when screwing the spear into grain. Many fans sold have much lower airflows that will take much longer to cool the grain and will ventilate a smaller area. Just because a product seems cheaper, it doesn’t mean it will do the job!

Additional options for a wider range of uses

Oil Seed Rape and Small Seeds

Grain and Rape PerforationsRape or Grain?

The Trouble-Dry aeration spear is available in two perforated versions – standard 3mm perforations to suit most grain types or smaller 1.5 mm perforations to suit use with oil seed rape and prevent rape seeds falling through the holes. Smaller holes mean less overall air space in the perforated section so we always recommend that the Trouble-Dry Extra fan is used with oil seed rape. The rape aeration spear is perfectly suited for use with larger grains.

We have also developed a special version of the Trouble-Dry aeration spear for use with even smaller seeds such as poppy seeds, which tend to be stored in smaller bulks. This is made to order, so please enquire for further details.

Spot Drying with the Trouble-Dry Ultra

The Trouble-Dry aeration spear is frequently used to carry out urgent spot drying in small heaps of beans, peas and even grains. The Trouble-Dry Ultra adds one of our Pile-Dry Pedestal Fans to the spear and increases the drying possibilities even further. Remember that ambient air cannot be guaranteed to dry grain and speed of drying will vary according to ambient conditions.
