A World of Opportunities

The planning of a fluidised bed plant requires a lot of specialized knowledge, not only about all the details of the process technology. Our expertise includes not only the perfect engineering, but also in-depth knowledge of raw materials and substances, regulations and standards, production processes, industries, markets and trends.

The configuration of your plant depends on several factors: Which product quantity do you intend to process per hour? What are the properties the starting material, which end product do you want? Which constructional requirements, which standards do you have to fulfil?

The fluidised bed apparatus is the core component of the plant. Numerous options are available to equip the plant in accordance with the application to be fulfilled. Depending on the design, fluidised bed processes such as drying, agglomeration and spray granulation can be carried out continuously in this system. Size and execution of the plant, the plant design and the peripheral components are individually adapted to the respective product and process requirements.

Customised Temperature Profile

The fluidising air enters the air distributor sidewise and is pressed from below through the distributor plate. Depending on the configuration we offer perforated plates or plates with special perforation. The concept of zone classification ensures that the plant can be used for an even wider range of applications. The fluidised bed plant is divided into several horizontal zones which are separately controlled as to air and heat. A customised temperature profile can be set over the length of the apparatus which can be individually defined for the process in accordance with the product properties. For example different supply air temperatures can be chosen for the agglomeration zone and for the drying and/or cooling zone. This does not only allow an energy saving operation mode, but also ensures gentle product processing.

Static or vibrating

A main feature of the Neuhaus Neotec Conti FB fluidized bed plants is the static or vibrating system, which are optionally supplied with internal filter cartridges. Vibration ensures a basic product fluidisation with a reduced air quantity and avoids strand formation at low expanding fluidised beds. This is helpful for sticky or heavy products. Vibration also helps to empty residues from the apparatus.

Integrated filter cartridges

Most of our plants operate with an internal filter system. This system reduces heavy product-loss during agglomeration, as the entire product quantity remains inside the apparatus. Fine dust is not discharged, but returned to the process for being agglomerated to the required product form. The connected outgoing air components stay clean; a product return unit is not required. The concept of internal filters reduces the cleaning effort, enhances the flexibility of the plant and is necessary for drying fine products.

Spray technique

The internal spray systems allow to use the fluidized bed process for drying and cooling as well as for other technical processes such as agglomeration, granulation and coating. To ensure long-term flexibility of the plant, a spray device should be included or provided as an option for later installation.
