摘要:
Described is an apparatus for continuously dewatering a fabric web in rope form. Said apparatus has a first compressor, a second compressor, a dewatering module, and a drive unit associated with the dewatering module to convey the fabric web in rope form through the dewatering module. The dewatering module is designed as a fabric web guide through which the fabric web in rope form is conveyed at an adjustable speed. The first compressor is connected to the fabric web guide at the pressure end, and the second compressor is connected thereto at the suction end, so that the fabric web in rope form which is to be dewatered and is conveyed through the fabric web guide is subjected at least once to compressed air and at least once to suctioning within the fabric web guide, the mass flow exiting the first compressor being adapted to the mass flow suctioned by the second compressor.

The invention relates to a dryer for drying a material web, in particular a material web (203) printed with inking units of a printing machine (101). In order to create a dryer for drying a material web that is run optimally for the task currently in progress, the dryer according to the invention comprises a drying section, in which the material web (203) is guided by deflection bodies (206), wherein the deflection bodies can be adjusted and/or the deflection bodies can be introduced into the web path and/or the deflection bodies can be removed from the web path in such a manner that the dwell time of the material web (203) in the drying section changes.

A functional roll incorporating a lattice-shaped fluid (gas-liquid) guidepath structure (8) made of high-density porous sheet material (300) to activate the internal pressure of the roll axis (4), whereby the lattice-shaped fluid (gas-liquid) guidepath structure consists of an internal pressure action space (1) made of a cut-out portion provided on the circumference of the roll axis (4) in the axial direction of the roll unit, and an internal pressure branching guidepath (6) made of low-density porous sheet material (7), or a space communicating with the internal pressure action space, provided in the radial direction of the roll unit.
摘要:
A system for reclaiming effluent from a freeze drying process has at least one condenser apparatus used during a freeze-drying cycle to collect effluent from material being freeze-dried, and a recovery reservoir positioned for collecting material from the condenser apparatus. The system is characterized in that ice crystals formed from the effluent are removed from the condenser, after the freeze drying cycle into recovery reservoir to be re-used. Product systems include both freeze-dried material and the effluent collected during freeze drying.

A system (50) for the processing of materials includes a freezing section (52) and a thawing section (54), with elongated channels extending through both sections (52, 54), and gates between the sections (52, 54) and at the output of the thawing section (54). Large blocks of frozen material are slid from the freezing section (52) to the thawing section (54); and a new batch of material is frozen with the heat from the freezing section (52) used to thaw the blocks of frozen material. A harvest bar (60) with dogs (64) extending into the frozen material traverses at least the freezing section (52), and spray nozzles associated with the harvest bar (60) may be used for cleaning the system (50).
