Drying nuts

Profit from our know-how in nut processing and increase your productivity in all processes.

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.

Machines for drying nuts from Feucht Obsttechnik

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.

Maxi dryer

The drying storage for large amounts.

Thanks to the Maxi Dryer, large quantities of nuts can be dried in a short time and with very good quality. Up to 1,000 litres of dried nuts can be produced approximately every 24 hours. During the drying process, the nuts are stored on 3 different height levels.

The lower level is the outlet used to empty the dry nuts. Then, both of the upper stages are opened so that the nuts fall down one level. The upper level can be filled with fresh nuts. The air stream is generated with a gas heater and a blower on the rear of the drying storage. The moisture of the nut can be checked using our additionally available
moisture meter.

Mini dryer

The gentle drying storage with expandable capacity.

With the Mini dryer, up to 40 litres of nuts can be dried. For this, an adjustable fan heater generates a warm, uniform air stream (36°). The fan heater is directly connected to the drying storage. A flap allows the moisture of the nuts to be monitored throughout the process. This means that the Mini Dryer can be used to achieve an excellent drying result.

The dry nuts are then emptied through a large outlet. The Mini Dryer has 2 stages. The capacity of the drying storage can be increased with an expansion (contains 2 levels).
