You “just” need a longer distance inside the drying chamber. This could be achieved by coiling up the space where the filament travels through and guide hot and dry air through that space, ideally from the outlet towards the inlet. That air could maybe be pulled from the hotend cooler.

Yes, that’s also what I already mentioned in the other comment…
“Unless you have a coil or something inside the tube heater so it spends longer time in there”
but as I also mentioned, pulling filamennt through a coil will also introduce significantly more resistance than pulling (or pushing if using bowden) it straight, which might be an issue at high speeds and cause under extrusion.
