MULTISPRAY® Cabinet Dryer is a vacuum tray dryer used for the processing of wet feed from filtering and centrifuging processes in the pharmaceutical, chemical, and cosmetic industry.
It guarantees total cleanliness of the inner chamber and all heating places, in compliance with the increasingly restrictive FDA and cGMP standards. In fact, thanks to C.I.P. MULTISPRAY®’s fast-washing system, equipment can be thoroughly cleaned in just a few minutes. The process is also repeatable and certifiable, which minimises washing liquid consumption.
The MULTISPRAY® vacuum has two versions available, fixed plate and removable plate.
Also, for the production of highly active pharmaceutical ingredients (high potency API) and for R&D activity, Italvacuum has developed the laboratory version LaboDry.
The MULTISPRAY® static vacuum dryers consist of a cabinet type chamber and a series of heating plates. Both the chamber and plate surfaces are heated by the circulation of fluid.

C.I.P. MULTISPRAY® patented fast washing system
With the C.I.P. MULTISPRAY® patented fast washing system, the drying chamber and inner plates can be washed and cleaned in just a few minutes, in a repeatable and certifiable way.
An innovative technology designed by Italvacuum to offer a double advantage: guaranteeing a perfect cleanliness of the inner parts using only a minimum amount of washing liquid and preventing the operator from coming into prolonged contact with possible product residues and solvents present inside the dryer. Also, the perfect airtight closing and the special MULTISPRAY® design eliminate any risk of washing liquid contamination in the surrounding environment.
The C.I.P. MULTISPRAY® patented fast washing system consists of C.I.P. diffuser,
mobile pneumatic washing unit.
Fixed shelves version
Total cleanliness and absence of any contaminating agents is essential for highly valued and delicate pharmaceutical products. The fixed shelves version satisfies such requirements thanks to the smooth geometry of the heating plates, minimum surface roughness, rounded edges and easy inner accessibility. Also, to make cleaning operations easier, the base of the cabinet is tilted towards the door in order to facilitate the removal and discharge of the washing water.
With a wide front flange and the set-back supporting systems, through the wall installation is possible, further isolating the clean room from the technical area.
Extractable shelves version
The MULTISPRAY® dryer with extractable shelves ensures all the advantages of the fixed plate version, but offers an important added value: it is equipped with shelves mounted on a completely removable single structure, guaranteeing total accessibility to all the internal surfaces exposed to the process. An innovation that makes total cleaning even easier and minimises the risk of cross contamination in case of frequent changeover operations.
The connection to the heating circuit by means of two fast couplings outside the chamber, allows the plate pack removal without a previous discharge of the heating fluid from within.
The plate pack is removed with the aid of an external hydraulic trolley, completely made of stainless steel and equipped with anti-static polymer wheels. With this trolley the operator can quickly handle the plate pack in extreme safety and without any difficulty. In addition, by using an external hydraulic trolley, no rails or wheels are needed inside the cabinet, that would make cleaning and swab testing really difficult.
The Italvacuum systems comply with ATEX directives and cGMP standards.
The LaboDry laboratory version was developed for the treatment of highly active pharmaceutical ingredients (high potency API) and to meet the production requirements of small batches. The laboratory version features separate cell construction and skid-mounted auxiliary accessories, ready for installation in a glove box.
The parts in contact with the product are built in AISI 316L (1.4404) stainless-steel. For special applications, where there are problems related to the aggressiveness of the products or solvents treated, materials such as AISI 904L (1.4539), ALLOY C-22 (2.4602) are used, or FDA approved anti-corrosion coatings, for example PFA. For external parts AISI 304L (1.4307) stainless-steel is used.
The MULTISPRAY® vacuum tray dryers have a vast range of uses and can be employed in the following sectors:
- Fine chemicals
- Food ingredients and additives
The MULTISPRAY® vacuum tray dryers were conceived to make the cleaning operations extremely fast, efficient, repeatable and certifiable. With the C.I.P. MULTISPRAY® patented fast washing system consisting of C.I.P. diffuser and mobile washing unit the chamber and inner shelves can be cleaned in just a few minutes, minimising liquid consumption. This is the great added value that distinguishes MULTISPRAY® dryers from the conventional static dryers.
In addition to total cleanliness of inner parts, this unique washing system protects the operator’s safety, by avoiding prolonged contact with possible product residues and solvents present inside the dryer. Also, the perfect airtight closure and the MULTISPRAY® special design eliminate any risk of washing liquid contamination in the surrounding environment.
C.I.P. MULTISPRAY® Diffuser
The C.I.P. MULTISPRAY® diffuser, equipped with washing nozzles capable of efficiently cleaning the walls and inner shelves, is quickly installed onto the dryer door. The nozzles have been specially designed and developed by Italvacuum in materials compatible with the process to guarantee maximum cleaning efficiency with minimum consumption of washing liquid.
Mobile washing unit
The mobile washing unit consists of a stainless steel tank complete with a PTFE membrane and pneumatic pump, which feeds the C.I.P. diffuser perfectly, guaranteeing maximum cleaning efficiency.
The washing cycle is operated and managed by a pneumatic control board situated on the mobile unit. Only a connection to compressed air is sufficient to make the system work. A valve allows the external collection of contaminated liquid after washing has been carried out, or alternatively its recirculation. A further guarantee against liquid contamination of the surrounding environment.
The mobile washing unit is equipped with anti-static polymer wheels, in compliance with ATEX directives and cGMP standards, and also enabling easy and safe handling.
The C.I.P. MULTISPRAY® patented fast washing system ensures an efficiency of more than 98% for plates inside the cabinet and of 100% with the plate pack extracted from the drying chamber. This result is certified by a washing test carried out by specialised personnel and proved with the use of riboflavin as a tracer substance.
Washing operations carried out with the MULTISPRAY® system guarantee perfect and repeatable results.
The MULTISPRAY® vacuum tray dryers are easy to clean also externally, thanks to the airtight door cladding. In addition the wide front flange and the set-back supporting system allows through the wall installation, further separating the clean room from the technical area.
Pilot trials: from laboratory to installation: the best way to choose the right industrial equipment
Italvacuum has a complete range of pilot systems, allowing to carry out laboratory and semi-industrial drying tests on customer’s products. During the test it is possible to take product samples for analysis and change the process parameters at any moment, to define the ideal drying cycle procedure. In this way clients have the possibility to make the most suitable technological decisions for their own requirements. The execution of the tests is completed and documented with a detailed report on the evolution of the main parameters and conclusions on the tests results.
In addition to the MULTISPRAY® vacuum tray dryer, Italvacuum can also supply components to complete the system, appropriately dimensioned to meet every process requirement:
- Saurus939 high vacuum pump
- Vacuum condensation group for reduction of drying times and recovery of extracted solvents
- Heating and cooling group for system thermal regulation
- PLC control board for total system management, equipped with software in compliance with the CFR 21 Part 11 standard, that guarantees the reproducibility of dried batches and can interface with centralised control systems.
