How much does a continuous flow grain dryer cost?

Continuous flow dryers cost more than a drying bin. The dryer itself may run as high as $100,000.

How much does a grain dryer cost?

A similar-capacity unit will run about $80,000 now, and farmers could be looking at about $150,000 for a complete set up with an elevator leg and a holding bin. Now, that said, many farmers already have some bins and fans that could integrate into a dryer system.

How does a mixed flow dryer work?

Mixed flow dryers are column dryers that have air flow in both counter and concurrent directions. Theses dryers often have multiple zones and can use higher air temperatures without crop damage than cross-flow dryers because like the concurrent flow dryers, all grain kernels are exposed to the same air temperatures.

How do tower grain dryers work?

TOWER GRAIN DRYER OPERATING PRINCIPALS The product enters the grain dryer from an extra-large wet holding bin at the top of the tower dryer and gravity pulls the grain down through the dryer in a hollow column, like the cement in a culvert. Rotary sensors for choke fill or surge fill are standard equipment.

How much does it cost to dry corn per bushel?

The energy cost per bushel to dry corn from 25 percent to 15 percent (10 points) is 42 cents per bushel (10 points x 4.2 cents per bushel per point of moisture). Total drying costs are higher since they include both energy costs and the fixed or capital costs.

How many BTU is a grain dryer?

New propane grain dryers use 1,650 British Thermal Units (BTUs) to remove a pound of water compared with older technology that takes as many as 3,500 BTUs. Propane has lower maintenance costs than traditional fuels due to its clean-burning properties.

What are the different types of grain dryers?

Batch Grain Dryers

  • Batch Bin Dryers. This is the simplest dryer requiring a storage bin with a perforated floor and a blower to move air through the grain.
  • High Temperature Bin dryer.
  • Roof Dryers.
  • Recirculating Batch Dryers.

What is the purpose of a grain dryer?

Grain drying is process of drying grain to prevent spoilage during storage. The grain drying described in this article is that which uses fuel- or electric-powered processes supplementary to natural ones, including swathing/windrowing for drying by ambient air and sunshine.

What are the drawbacks of batch dryer?

Their major disadvantages are that they cannot be easily automated, so require more supervision and labor per bushel than other types of dryers and they have a large temperature and moisture variation across the grain column. The energy efficiency is about 2,500 to 3,000 Btu per pound of water removed.

What is a continuous flow grain dryer?

Continuous flow grain driers allow you to immediately dry your crops, independently from weather conditions, at the rate they come off the combine. A well designed installation will make drying vast tonnages, for months on end, simple.

What does a grain dryer do?

The drying process is based on the diffusion of moisture from the inside of the grain to the outside. The hot and dry air that touches the grain leads to a heating of the humidity inside the grain which tends to evaporate to saturate the hot air.

Is it worth drying corn?

“If you can scout your corn well and find areas that have good stalk quality, then some field drying of the corn may be in order. However, for fields with significant stalk rot and risk of lodging, the risk/reward tradeoff of field drying the corn vs. harvesting it wet and artificial drying is worth a good look.”
