Method and fluidization apparatus unit for treating a large number of batches of a material having a moisture content

A method for treating a large number of batches of a material having a moisture content and a material temperature in a fluidization apparatus unit comprising a fluidization apparatus, wherein the fluidization apparatus of the fluidization apparatus unit has a fluidization chamber which has a material inlet and a material outlet, and which also comprises a fluid inlet and a fluid outlet for a drying gas which fluidizes the material in the fluidization chamber and which has a drying gas moisture content, the method comprising:

• during a treatment of the material of a batch in the fluidization apparatus in a first treatment period, at least part of a liquid which constitutes the moisture content of the material of the batch introduced into the fluidization chamber is evaporated by a supplied heat provided by the drying gas, such that the material of the batch cools down from an initial material temperature to a material minimum temperature as a result of an associated removal of evaporation heat;
• and
• in a second treatment period, liquid is further evaporated by the supplied heat provided by the drying gas, such that the material of the batch heats up to a material end temperature, and consequently the moisture content of the material of the batch is reduced to a residual moisture content,
• wherein the material end temperature is found as a sum of an individual material minimum temperature for the material of a batch and a prespecified increase temperature that is a same value for each batch of the material.
