Discontinuous fluid bed apparatus for batchwise operation.
Batch processes are particularly appropriate for the processing of different products with changing production quantities. In Batch FB systems the process phases are executed in rotation as a difference to continuous processes. This results in an extremely large potential for the variation of process settings and the production of very complex products. Anyhow the more efficient and flexible a batch plant should be, the more important is the overall engineering from the process technology to the selection of the appropriate peripherals.

• Drying, agglomeration, spray granulation, coating
• Pressure shock resistant design up to 12 bar
• Single-chamber, double-chamber shaking filters, blow back filter cartridge systems
• Top or bottom spray facilities
• Various product feeding and discharge concepts

Fully automated fluid bed system for continuous operation.
Continuous plant operation is frequently used for mass production whenever price-sensitive markets require highly automated production processes. The concept of the fluid bed systems Conti FB is based on a modular design with separate inlet and exhaust air zones. Continuous, fully automated operation of the plant requires only few operators and a minimum of effort.

• Multi-stage operation
• Top or bottom spray
• Internal or external filtration system
• Vibrating or static systems
• Nozzles in every section, height adjustable, removable
• Product weirs for sectioning
• Through-the-wall installation: separation of technical/production area

Even at low production capacities of 10 kg/h the continuous process is e.g. for the pharmaceutical industry an interesting alternative to traditional methods.

Laboratory Fluidized Bed (LFB) Batch S/M
Fluid bed system for universal laboratory processes in small quantities
The LFB (Laboratory Fluidized Bed) is a mobile batch fluidized bed system with integrated air treatment (heater, fan and filter elements) as well as pneumatics, control and optional constructive explosion protection. The unit has a modular design and can be operated with exchangeable product bowl, filter housings, bottom air plates, spray systems, etc. This individual equipment offers the possibility to use the LFB for all fluid bed processes in the laboratory, pilot plant or small quantity production scale:

• Drying, agglomeration, spray granulation, encapsulation, coating
• Interchangeable process towers: Standard (5 l / 10 l / 20 l), Maxi (10 l, 20 l, 30 l)
• Special Spouted Bed Coating version with two separately controllable supply air flows and special bottom sieve plates
• Batch sizes from 250 g to approx. 18 kg
• max. supply air temperature 180°C
• max. air volume flow standard 300 Nm³/h and Maxi 600 Nm³/h
• Top- and Bottom-Spray processes, Spouted Bed Coating, Wurster Technology
• Pivotable and tiltable product bowl
• Cartridge filter system with compressed air cleaning
• Integration of an agitator possible
• Sight glasses in material containers and filter housings
• 10 bar pressure shock resistance with optional quick-acting shut-off valves in housing
• Integrated peristaltic pump
• Smart program design for optimal process control with recipe creation
• Data logging via USB interface

In addition to the LFB, we offer you further high-performance laboratory systems for pilot and small-scale operation, both for continuous and batch processing.

Flexible plants by Neuhaus Neotec for continuous and batch-operated fluid bed processes. In the fluid bed, the conditions for intensive heat and mass transfer are optimum. Fluid bed processes are most effective and versatile:

• Thermal treatment of bulk products (drying and cooling)
• Formation of particles from powders (agglomeration)
• Formation of particles from liquids (granulation)
• Coating and encapsulation

With fluid bed processes the application properties of powdery or liquid raw materials can be optimised. Various processes can be combined in one plant and can be carried out fully automatically.

From the machine to the overall system

We offer a holistic approach for both continuous and batch-wise operated fluid bed plants. In addition to product and process development in our pilot plant, we take care of the design and configuration of a plant according to your needs, including all peripheral equipment such as air handling system, product supply, product discharge and control system. In addition, we also act as general contractor for the design of complete production lines.

Safe parameters prior to production.
In our modern pilot plant we offer extensive technological equipment to perform all fluid bed processes on a laboratory or pilot scale with reliable results. Continuously or batchwise. For drying, agglomeration, spray granulation, coating or micro-encapsulation.

Pilot plant FB 20/4
Our fluidised bed pilot plant FB 20/4 available in the Neuhaus Neotec pilot plant has been developed for processes from 5 to 50 kg/h. Thanks to the flexible plant configuration, this capacity range can be easily scaled up to larger production sizes. The plant is characterized by a high degree of flexibility. It provides manifold possibilities of inlet air conditioning (humidification / dehumidification), vibration, top/bottom-spray, process balancing. In addition, it meets all requirements on hygienic production (GMP).

We also have several small plants for preliminary tests in the batch mode.
