Definitions

the invention relates to a contact belt dryer, consisting of an endless conveyor belt for transporting a product to be dried, a lower heating plate arranged below the conveyor belt, an upper heating plate arranged above the conveyor belt, a gas distribution device for hot gas and a gas suction device.
Contact belt dryers are used, for example, for drying dyes and pigments with frequent product changes.
the task was therefore to significantly increase the evaporation performance of the contact belt dryer without impairing the ease of cleaning.
the gas distribution device is integrated in the upper heating plate and is designed as a perforated plate.
the contact belt dryer consists of an endless, driven conveyor belt 1, which is deflected via two rollers 2.
a lower heating plate 3 is arranged below the conveyor belt and an upper heating plate 4 is arranged above the conveyor belt.
the product 5 to be dried migrates through the contact belt dryer during the drying process.
the upper heating plate is designed as a perforated plate 6.
the hot gas 7 flowing to the contact belt dryer is deflected via a baffle plate 8 arranged perpendicular to the gas flow direction, then flows through the perforated upper heating plate and over the product to be dried.
the gas serves on the one hand to discharge the vapors - which flow out of the product when it dries - and on the other hand to supply heat to the product.
This gas / vapor mixture is sucked out of the contact belt dryer via the gas suction device 9.
the speed of the outflowing gas should be 1-2 m / sec, based on the free cross-section.
the distance between the conveyor belt and the upper heating plate - perforated plate - should be between 100 and 300 mm.
the hole diameter in the perforated plate should be between 1 and 4 mm, the hole spacing should be 10 to 70 mm.
perforated plate can also be produced with slot nozzles or similar embodiments.
