Definitions
- the drying temperature may be in a range of up to 120 ° C, for example.
- the heated dry air flows through the small parts bed on the upper strand and thereby takes Moisture on.
- the chamber area above the belt upper run can be sealed in such a way that in the chambers (48) the supply air can only flow through the heating register (45).
- the heating registers may in this case have a smaller area size than the chamber base area.
- the drying device (3) may be formed as a stationary sieve dryer, in which the small vegetable parts are poured onto tray or pallet-like sieves and are flowed through in a drying oven by heated dry air.
- Several sieves can be housed in a rack or dolly.
- the guidance of the dry air flow may be different and need not be guided transversely to the main plane of the small parts carrier (36). There may also be oblique or parallel flow directions.
- the steam is supplied to the strand (2) in the manner explained below from the inside with an internal supply (26) through at least one channel-like opening.
- FIG. 3 shows this variant.
- the steam can be supplied from the outside with an external feed (25) to the strand casing according to the in FIGS. 4 to 8 shown variant.
- the strand (2) is e.g. saturated steam in a controlled amount of steam via the steam outlet region (27) and fed to the feed.
- the amount of steam and the vapor pressure are matched to the heat capacity of the applied strand area and e.g. so dimensioned that the supplied steam provides in this strand area for the required setting and thereby substantially completely condensed. Excess steam can be substantially avoided, so that the strand (2) on the outside no steam or little steam escapes.
