The mesh belt dryer needs routine upkeep

A drying apparatus includes a plurality of mesh belt dryer modules, each module creating a drying zone and having a plurality of tubes disposed above and below an upper surface of a conveyor that supports a product within the apparatus for transport therethrough. At least one circulation fan in each module causes heated air to circulate to the tubes, which direct the air flow to impinge upon and dry the product. Each module also includes a burner for heating the air within the module to a desired temperature. The circulation fan and burner of each module are independently controllable, so that the apparatus can produce an air-flow rate and an air temperature in at least one of the drying zones different than the air-flow rate and air temperature in at least one other of the drying zones.
The mesh belt dryer is flexed sufficiently to cause certain movement of the mass upon the belt without agitating the mass. The normal drying action of the heated air is to be that the heated air flows through the mass of material and not around clumps of the fibrous material. For example: if the flexing of the mesh belt dryer is so vigorous that seed cotton is separated into individual locks, the air tends to flow around the locks. The seed cotton is dried better if the mass of material remains intact with the air flowing through the locks.
The main preferred method of flexing or undulating is by having the belt carrying the mass of seed cotton upon it over intermittent "V" shaped supports. This permits sufficient flexing or undulating to release trash from seed cotton without forming undesirable air passage ways through the mass.
Also, the mesh belt dryer is secondarily flexed by bumper rollers beneath the mass flexing the belt upward at points where otherwise the belt is sagging downward between the intermittent supports. The bumping of the belt is also restricted to cause the flexing to be within the above parameters.

It will be understood that the mesh belt dryer34 will be flexed by the bumping of the belt from below and also be flexed as it is run over intermittent "V" shaped supports 86. The flexing of the belt will shake the fibrous material, aiding in the release of trash from the fibrous material, thereby aiding the cleaning of the material. The shaking will also prevent excessive packing of the fibrous material from the downflow of the treated air downward through the mass of the fibrous material.
