TCOIL dimple jacket exchangers in application for the cooling and heating of wheat grits, coming from silos or aimed to be stored in silos. This is a very common application in north-American markets.
Wheat grains are indeed heated to get dry before these are stored, or otherwise cooled when coming from silos that are too hot to allow the wheat to be exposed to ambient air.

The TCOIL exchanger with spot-welded and inflated plates in this case is composed by a battery of 30 plates with double dimple, each plate has a size of 1000 x 1000 mm and the plates are mounted with 20 mm pitch. The material is AISI 304, with thickness of 12/10 mm of the metal sheets and two flanged connections type DN 80 PN10 with square collector.

The dimple jacket heat exchanger battery is immersed in a parallelepiped shaped vessel, within which wheat grains are poured. Low pressure steam flows inside the plates to achieve heating, while refrigerated water at a pressure of 3 bar is employed for the cooling task.
A very similar application has been realized for the cooling/heating of granular plastic materials.
