Tell us about your production challenge

The average corn cob has 800 kernels, but each of those comes from one tiny grain. The quality of corn farming rests on the conditions of foundation lots. And these depend on the integrity of the process. Corn seed processing equipment prepares the grains so they can grow into multiple products ranging from food to energy to cosmetics.

Apply gentle drying to avoid harming the maize seed

Harvested corn contains about 25% moisture content, a risk to the seed quality. Water incubates microorganisms that spoil the seeds.

But the crop is sensitive to high temperatures, and aggressive moisture reduction methods threaten the seed embryo. Specialized seed drying technology applies gentle heating over an extended period to release the excess water without harming the seed.

Adjust the threshing parameters to the corn variety

Maize is more robust than other seeds, so the threshing mechanism must apply higher pressure with a faster rotation speed. Automatic corn seed processing equipment adapts to the plant material.

However, if you’re using a manual unit, you must set strict parameters to ensure that all grains are removed from the cob. Adjust the threshing gap between the plate and the groove to the correct size, and make sure not to overfeed the machine.

Separate the grains with specialized corn seed processing equipment

The kernels may be freed from the cob, but they still carry potential contaminants. Accurate cleaning is critical to maintaining the quality of breeding and foundation seeds.

A system of sieves separates the corn from soil and extraneous matter. The seeds, however, must similarly be sorted into different lots. Separation systems calibrate the kernels by size, weight, or density, while optical sorters pick out inconsistencies.

Coat the kernels to stave off insect raids

Retaining a high yield at the end of a complex process is already challenging. But seed producers must also contend with pest attacks.

Treat the kernels with a protective solution to keep rootworms and other corn insects away. The mixture typically contains fungicides such as carbendazim and thiram, but formulas vary per supplier.

Apply a homogeneous layer around the grains

Specialized coating equipment for seeds applies a uniform layer around each grain. Each kernel must be covered entirely in the protective film to prevent contamination later on during storage.

Different machines use a variety of techniques to perform the coating. While some technology dips the kernels in the solution, rotary systems pour it over the seeds.
