Drying nuts carefully and quickly.
Preserve nuts using drying storage or heating devices.
After washing, the nuts must be quickly dried. Drying not only ensures a high quality of the precious nut cores by preventing mould, but also a long shelf life of the nuts. The fresh nuts are dried in a warm, dry air stream with temperature between 20° and 36°C up to a residual moisture of approx. 5 – 12%. The temperature control however depends on the size and the degree of moisture of the nut.
The drying process can be carried out with nut storage or special heating devices for nut drying.
Multi-level drying storage
Drying nuts efficiently and economically.
The multi-level drying storage system allows the nuts to dry uniformly by constant movement. The walnuts are pre-dried in the upper levels and finish drying in the lower levels. This allows for a higher air temperature (30° to 36°C).
The nuts are transported from top to bottom by gravity. The drying capacity can be expanded through the addition of sections. The multi-level drying storage for nuts is equipped with several hinged doors and a central opening. In addition, the drying storage is available with helicoidal or centrifugal heating with different heating capacities according to the size of the storage. The degree of moisture of the nuts can be checked with the optionally available moisture meter.
Benefits
•the drying sections are galvanised and screwed (supplied in building kit for self-assembly)
•size of the drying storage is expandable through the addition of sections (up to 4 levels)
•centrifugal or helicoidal heating with different heating capacities, dependent on the size of the drying storage
