Grain Dryer

Grain drying is an integral part of the farming operation, and LPG is most often used to fuel heated-air drying systems because it is portable, can be easily stored, and is readily accessible in rural areas where natural gas is unavailable.

LPG-fuelled moisture-control technologies prepare crops for harvest and storage and are capable of drying virtually any type of grain. They are available as either batch dryers (where grain is dried in batches ranging from 80 to 1,000 bushels) or continuous flow dryers (wet grain is fed into the dryer in a steady) – both types are available in the form of mobile and static grain dryers. Grain drying increases the quality of harvested grain by reducing crop exposure to weather, and it allows more time for post-harvest field work.

Features

General features associated with LPG dryers include:

  • A full range of temperature settings catering to a variety of grain types.
  • A full range of temperature settings catering to a variety of grain types.
  • Fully-automated filling, unloading, and shut-off capabilities.
  • Quick and easy full length clean-out doors to facilitate grain changing without contamination.
  • Control panels to indicate the operating status of equipment as well as the sources of problems in the event of a shut-down.
  • Long operational life and very low maintenance requirements.
  •  A choice of fuel storage options; LPG tanks or gas cylinders, ensuring the most convenient and cost-effective supply of LPG to cater for your individual needs.

Some features associated with specific models:

  • The capacity to operate in three modes: pressure heat and pressure cool; all heat; and pressure heat and vacuum cool. The flexibility allows farmers to customize their grain drying cycles.  Low-profile vacuum-cooled dryer features a horizontal, modular design with a centrifugal fan for quiet operation.
  • The ability to circulate the grain during the drying process, maximizing grain quality and minimizing fuel use and operating costs. This eliminates over-drying and maintains optimal grain temperature and efficiency.
  • Features such fans and heaters at both ends of the dryer to distribute heat more evenly resulting in more even drying. Alternating air flow direction increases efficiency and eliminates front-to-back moisture variation and heat loss.

Benefits

LP Gas is a highly controllable fuel and facilitates effective drying of fruit and grain; reducing over-drying (optimum drying conditions are consistently maintained) and producing more evenly-dried, higher-quality grain. The complete combustion process further reduces the chance of grain combustion, water ingress or fuel sediment embedment. Wheat, maize, barley, rapeseed, peas, potatoes, bulbs and onions can all be dried economically and efficiently. This allows farmers to preserve the quality of their crops and to meet specific market specifications for moisture content for storage and onward sale.

LPG grain drying technology recycles heated air and converts 90% of the LPG used to energy which enhances efficiency, lower fuel consumption and lower costs. They require as little as 1,650 British thermal units to remove a pound of water, compared to 3,500 with older technology.

They expand the harvest window and reduces crop loss caused by weather and mechanical harvesting when crops are left to dry in the field.

The environmentally friendly equipment utilises a clean burning fuel and eliminates soot build up.

It reduces the need for chemical application, produces healthier chemical-free crops, eases the harvest process, and increases food safety and unlike fuel oil or kerosene, LPG will not leak and contaminate the grain.

LPG grain dryers also limit fungus and bacterial growth and can allow farmers to harvest their crops with some flexibility, more independently of the weather.
