    摘要： Purified water for special purposes is produced using a falling-film multieffect evaporator. From the feed water, each effect produces a steam phase and a water phase. The steam phase is used for heating in the subsequent evaporating step, whereby the steam phase condenses to product water, and the water phase becomes feed water for the subsequent evaporation step. According to the invention, the product water may be wholly or partly recycled to the initial feed water, allowing process startup and sterilisation of the plant without conducting hot product water to the drain.

    摘要： The invention relates to a method and a device for the production of pure steam. A falling-film evaporator is used. Of the water-steam mixture leaving the evaporator unit, part of the water is collected at the bottom of the device, and a fraction mainly consisting of steam enters a rising spiral channel for the separation of impurities. In the periphery of the spiral channel apertures are provided for separating impurity-containing droplets, which condense on a surface outside the apertures. The liquid formed is removed from the device. The water phase collected at the bottom enters a recycle line connected to the feed end of the evaporator unit. Feed water is supplied to the recycle line to compensate for pure steam consumption.

    摘要： A structure for a multiple-effect still includes a horizontal shell encompassing a plurality of effects and a series of vertical compound baffles fastened to the horizontal shell and dividing it into a series of pressure-tight chambers. Each chamber along with its associated apparatus constitutes an effect. Each compound baffle comprises a fixed baffle and a removable baffle. A heat exchanger is fastened to the removable baffle and includes an evaporation surface, a condensation surface, and a pressure chamber isolated from the pressure-tight chamber in which it is located. A port in the compound baffle allows evaporate to pass between the pressure chamber and the pressure-tight chamber of an adjacent effect. The shell is provided with a removable top plate to provide access to the heat exchanger and allow removal of the heat exchanger and removable baffle.

    摘要： This invention relates to a process and/or method and associated apparatus for use in spray freeze drying a fluid substance such as fruit juice, pharmaceuticals, nutraceuticals, tea and coffee. A fluid substance is sprayed (atomised) and reduces in temperature to below its eutectic temperature; thereby inducing a phase change of fluids in the fluid substance. The atomised fluid substance (AFS) is then subjected to a vacuumous drying chamber in which the AFS is subjected to an energy source to assist sublimation of fluid from the AFS as it is conveyed through the chamber. Such an energy source can provide a temperature gradient through which the AFS passes and is exposed to, all carried out so as to preferably minimise or reduce the likelihood of degradation of the substance being dried (reducing the fluid content).
