Process for energy-efficient drying of germinated seeds and device for implementation of the process

A process for energy-efficient drying of germinated seed in a drying kiln using a rotational speed-modulated fan for directing an air mass flow through a bed of drying material for the germinated seed, comprising:

• detecting a grain moisture content and a grain mass of a grain which is a basis for the bed of drying material of the germinated seed after steeping and germinating;
• detecting an ambient air humidity for ambient air used for the air mass flow;
• detecting weather forecast data, at least with respect to the ambient air humidity;
• monitoring, while drying, a drying material moisture content of the germinated seed up to a specified limit;
• and
• setting a rotational speed modulation of the fan such that a specified maximum kiln time is reached and/or maintained, based on the moisture content of the grain, the grain mass, the ambient air humidity, the weather forecast data, and a moisture content of the drying material of the germinated seed.
