Apparatus, useful to heat hydrated organic solid materials e.g. fruit within heating chamber, includes preheaters, intermediate chamber, vacuum chamber, steam jet ejectors, and device to regulate condensation pressure of preheaters

摘要

The apparatus comprises preheaters (R1, R2, Rn, Rn+1) powered by a heating stream at an increased pressure level, an intermediate chamber (CI) for storing the heated raw material, a vacuum chamber (CV) connected to a condenser (Cr), steam jet ejectors (T1, Tn-1) feeding the preheaters, and a device for regulating a condensation pressure of each preheaters. The preheaters: are mono-tubular type preheaters, where a wall and a diameter of the mono-tube define a turbulent flow corresponding to the desired heat exchange; and receive the vapor emitted from the vacuum chamber.

The preheaters: are mono-tubular type preheaters, where a wall and a diameter of the mono-tube define a turbulent flow corresponding to the desired heat exchange; receive the vapor emitted from the vacuum chamber; receive the mixed vapor from the steam jet ejectors that define a heating steam pressure; and receive the heat of expanded steam from the boiler. The steam jet ejectors are mono- or poly-nozzles. The vacuum chamber comprises an inlet for allowing the distribution of solid material, and an anti-priming device. The emitted vapor does not contain solid or liquid particles. The preheaters are equipped with a vacuum device comprising a single vacuum pump connected to n-pairs of valves or vacuum pumps connected with a vacuum beaker. An independent claim is included for a process for heating hydrated, mechanically transferred organic solid materials within a heating chamber.
