The plants we design for the food industry make up a large part of our business
. The advantages they bring are considerable, in the face of a growing market demand.
This year, due to the pandemic, the demand for cereals has increased
. FAO estimates that world cereal production in 2020 will exceed last year by 2.6%.
So, how does pneumatic conveying technology work? And what benefits does it really offer?
How dense phase pneumatic conveying of cereals works
Millions of tons
of bulk grains are handled every year. With these production volumes, a technology capable of efficiently moving the product and avoiding breakage brings considerable benefits.
The fundamental principle
on which dense phase pneumatic conveying is based is low conveying velocity.
The percentage of breakage
of the material is proportional to its average speed in the conveying line. In a dense phase conveying system the material is slowed down to a speed lower than that at which the material could break or degrade.
Adopting a dense phase system capable of avoiding the degradation of a grain of rice, wheat or corn means reducing production waste and therefore optimizing costs.
Pneumatic conveying of cereals: the advantages
One of the most recent dense phase pneumatic conveying systems of cereals has been adopted by Pates Warda
, an agri-food company in Tunisia, for cous cous handling.
Three couscous transport lines with different grain sizes
for feeding the packaging machines ensure the optimization of production costs and a significant economic advantage for the company.
The low speed
of the pneumatic conveyors for cereals
allows to limit both the breakage of delicate products and the wear of the pipes. Furthermore, the typical plug shape that the product assumes inside the pipe helps to preserve the integrity, in the case of mixtures or agglomerates of cereals.
