Vacuum tray dryer – MULTISPRAY® Cabinet Dryer


MULTISPRAY® Cabinet Dryer is the result of 70 years of experience in the vacuum drying of wet powders, pastes and dense liquids, used in chemical and pharmaceutical production.

It consists of a main body completely heated by means of a liquid circulation circuit, so as to avoid any condensation phenomena, and by a series of shelves heated by means of a fluid distribution collector which guarantees heat homogeneity on all radiating plates.
MULTISPRAY® Cabinet Dryer stands out for the following main technical features:
  • Perfect mirror polishing of the inside of the cabinet
  • Perfect mirror polishing of the heating plates that are completely smooth on both upper and lower surfaces for a thorough and easy cleaning
  • ‘Particle-free’ trays for the complete recovery of the powders
  • Possibility of clean room installation well separated from the machine room, so ensuring a controlled environment

MULTISPRAY® Cabinet Dryer is designed and manufactured in full compliance with the ever more strict FDA and cGMP norms prescribed for machines employed in the pharmaceutical industry, especially with regard to the ease with which the inner chamber and the heating plates can be totally and perfectly cleaned thanks to the new CIP MULTISPRAY® Fast Washing System, covered by international patents.

New CIP MULTISPRAY® Fast Washing System

The new CIP MULTISPRAY® Fast Washing System is an Italvacuum patent that allows to carry out in few minutes the washing and cleaning operations of the drying chamber and of the inner shelves, preventing the operator from coming into direct contact with possible residuals of product and/or any solvent that could be found inside the dryer. Furthermore it eliminates any possibility of contamination between the clean room and the technical room.

CIP MULTISPRAY® Fast Washing System consists of:

  • Mobile CIP pneumatic washing unit
  • MULTISPRAY® diffuser placed inside the dryer

In the process of washing few rinsing liquid is used. In order to guarantee a minimal consumption of solvents, the heads of the CIP MULTISPRAY® diffuser are made directly by Italvacuum.

The efficiency of the new C.I.P. MULTISPRAY® Fast Washing System is certificated by means of a demonstrative proof through a tracer substance (riboflavin); at the end of the proof the following documentation is normally issued:

  • Inspection report of the system
  • Washing procedure according to cGMP norms.

The efficiency of the system can be increased up to 98% with the plates inside the drying room and up to 100% with the plates outside the drying room.

It must be underlined that the washing operation, being automatic, is repeatable, that is the achieved result is the same from time to time.


The following two types of executions, which are suitable for every type of application and use, are available:

  • Vacuum tray dryer with fixed plates
  • Vacuum tray dryer with extractable plates

Both the executions are designed to be equipped with the new CIP MULTISPRAY® Fast Washing System.

Italvacuum recently introduced a new range of tray vacuum dryers developed for laboratory scale. These dryers, manufactured with separated cells and auxiliary fittings mounted on skid, are designed for assembly in the glove box.
