Multispray vacuum cabinet dryer with Washing System

-        The "particle-free" tray system allows to completely extract dried product without leaving any residues on the surfaces of the dryer. This is especially important in case of expensive substances.

-        Precise machining of all parts and surfaces of the cabinet allows reaching a deep vacuum level in the cabinet and guarantees thorough and easy cleaning.

-        To ensure the safety of drying process in case of using explosive solvents, the cabinet can be equipped with an automatic nitrogen purging system.

-        For GMP application the cabinet can be installed "through the wall", when only the front panel and the door are located in a clean room, the rest of the structure is installed behind the wall in the technical room.

-        Special design makes the doors completely gas-tight and resistant to deep vacuum.

-        Recently Italvacuum introduced new automatic door opening / closing system. The door is operated by a ATEX compliant hydraulic system with vertical movement. This innovation, coupled with an automatic dryer loading and unloading system, provides the ideal solution for high toxic risk productions, preventing the personnel from having any contact with the product.

-        C.I.P. MULTISPRAY^® patented fast washing system guarantees perfect cleanliness of 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. Drying chamber and inner plates can be washed and cleaned in just a few minutes, in a repeatable and certifiable way.

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 minimizes 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 antistatic 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.

Cleaning

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, minimizing 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 antistatic polymer wheels, in compliance with ATEX directives and cGMP standards, and also enabling easy and safe handling.

Certified efficiency

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.

External cleaning

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.

The Italvacuum static vacuum dryers are available in a vast range of dimensions:

(W = width; H = height; D = depth)

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.

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 centralized control systems.
