Definitions

Contact belt dryers are used for drying dyes and pigments with frequent product changes.
Such contact belt dryers are described, for example, in the patents BE-A-45 36 54 and US-A-3,403,456.
the heating plates arranged above and below the conveyor belt are designed with or without holes.
the task was to significantly increase the evaporation performance of the contact belt dryer without impairing the ease of cleaning.
a contact belt dryer consisting of a noble conveyor belt for the transport of a product to be dried, a lower heating plate arranged below the conveyor belt, a heating plate arranged above the conveyor belt and designed as a perforated plate, and a baffle plate arranged perpendicular to the direction of flow of a hot gas for deflecting the gas and a gas extraction device.
Embodiments of the contact belt dryer according to the invention are the subject of the dependent claims.
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 is used 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.
