Description

The design of the equipment offers excellent performance for drying products and media in a pharmaceutical production setting:

• Highly robust and reliable: A rectangular cross-section chamber with two hinged doors, constructed totally from AISI 316 stainless steel with 3 filtering stages in the inlet assembled from F7, G4 and H14 filters. The exit side of the chamber can have HEPA 99.99% (H14) filters that prevent particles from exiting as the air is renewed 100%.
• Sanitary design: All the unit's components and pipelines (valves, heat exchangers, fans, filters, etc.) are supplied with quality certificates, in accordance with pharmaceutical industry standards, and have been designed for a long operating life and easy maintenance.
• Production performance and safety: The unit is equipped with steam or electrical elements to heat the load, dimensioned to offer an optimum balance of energy and cycle time. Pressure gauges provide notification of chamber overpressure and filter clogging. Temperature sensors enable process adjustment, control and recording.
• Easy to operate: The standard control system is comprised of a PLC connected to a touch screen terminal. A 3-channel recorder and thermal printer complete the MicroSter control, supervision and recording system. As an option, it can be supplied with a SCADA system.

Applications

Hot air drying (ultra-filtered or otherwise) is a method of drying non-thermolabile chemical and natural products for preparation or conservation purposes. The air which flows inside the chamber has been previously filtered using a HEPA filter to avoid product contamination. The process is completed statically, with the product inside trays. For this reason mechanical fatigue does not occur and the granulometric measurement, porosity and volume of the products are not changed.

The residence time of the product is completely defined and high quality homogenous products result. These pieces of equipment enable a large variety of products to be dried for the fine chemical, chemical-pharmaceutical, cosmetic and food and agriculture industries, such as:

• Medicinal plant extracts, food additives, spices and condiments, etc.
• Dried products which require a low final water content.
• Products which may have a tendency to form lumps, appear dough-like or thick and have a high initial water content.
