Laboratory Fluidized Bed Granulator

The laboratory fluidized bed granulation (spray liquid) is a method for making free-flowing granulate from liquids. Laboratory fluid bed granulation can be used in different applications in various industries, since the product properties can be varied in many ways by setting process technical parameters and configurations. The granules that maked by the laboratory fluid bed granulator machinery are suitable for making tablets, and the granules also for final coating by the laboratory fluid bed coating machine.
Many industrial applications require converting liquid substances into a stable product form with exactly defined properties – whether for further processing as a solid for Pharmaceutical, food products, animal feed or cleansing agents, for increasing stability in chemical substances or for handling thermally sensitive products such as enzymes, proteins or micro-organisms. Lab Spray granulation in the fluidized bed permits liquids to be directly made into free-flowing granulate with specific product properties. Generally, the granules also have instant properties.

Laboratory Fluidized Bed Granulator Introduction

Hywell machine Laboratory Fluidized bed granulator machine use the liquids containing solids, such as solutions, suspensions or melts, are sprayed into a fluidized bed system. Due to the high heat exchange the aqueous or organic solutions evaporate immediately, and the solids form small particles as starter cores. These are sprayed with other liquids which in turn, after evaporation, form a hard coating around the starter core.

This step is continuously repeated in the lab scale fluidized bed so that the granulate grows layer by layer like an onion. Alternatively, a defined volume of suitable starter cores can be provided. In this option, the liquid only serves as a vehicle for the solids that are being applied.

This process variant is often used in a continuous lab fluidized bed system with air-classifying discharge. Through the continuous removal of the finished granules from the drying room, the amount of particles in the fluidized bed remains constant.

The granules can be very dense because they have grown in layers, and are thus resistant to abrasion. Parameters such as particle size, residual moisture and solids content can be specifically adapted in order to achieve the most varying product properties. Using spray granulation, medium-sized particles of 50 micrometers to 5 millimeters can be produced.

The Laboratory Fluidized Bed Granulator also used as the dryer function, it is the Laboratory fluid dryer (lab fluid bed dryers).

Hywell Machinery also has industrial fluid bed granulator from 15kg to max 500 kg if high volume granulator are required.


Laboratory Fluid Bed Spray Granulator Description

Heated and purified air flows into the column by suction fan, the pellet or powder will be in uniform fluid condition inside the column, use one set of filter bags to prevent leak of powder, discharge the evaporated water to get draying purpose. If add one more spray gun can spray the binder or active ingredient downward into the uniform fluid powder, whenever the powder combined in granule will be dried to get the required moisture content.

Laboratory Top Spray Granulator

The lab top-spray granulator agglomerates finer particles into larger, free flowing granulates in a one-pot process. Ingredients are mixed and preheated by an upward flow of heated air. Granulation occurs by spraying liquid into the fluidized powder. The granules are subsequently dried with heated air. The top-spray granulator can also be used for top-spray coating, layering from liquids and instantizing. Special features include a selection of air distributors and one-pot processing.

Drying of Lab Scale Fluid bed spray granulator

Warm air is blown through a perforated distributor to rapidly and gently dry the formulation until the required residual moisture content is reached. Moisture evaporated from the product is exhausted with the drying air. Special features include a selection of air distributors and short processing times.

Lab Fluid Bed Granulators Construction Material

Hywell Machinery are able to offer our FL series lab scale fluid bed granulators with contact part to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. For the control system of Laboratory scale fluid bed granulators, Hywell machinery have choices on push button, PLC+HMI and so on, and For the main electrical components of the super mixer granulator , it can choices the famous brand that such as ABB , Siemens or Schneider or others.


How do the Laboratory Fluidized Bed Granulator works

In a Hywell machinery FL series lab fluidized bed granulator, The powder granule in vessel (fluid bed) appears in the state of fluidization. It is preheated and mixed with clean and heated air. At the same time the solution of adhesive is sprayed into the container. It makes the particles become granulating that contains adhesive. Being of unceasing dry through hot air, the moisture in the granulating is evaporated. The process is carried out continuously. Finally it forms ideal, uniform and porous granules.


Laboratory Fluid Bed Dryer Granulator Advantages

Hywell machinery lab fluid bed dryer granulator had the following advantages over conventional solutions.

1. Use for both drying and granulating processes.

2.Inspection windows.

3.Inlet air temperature probe.

4. Product temperature probe (optional).

5.100 micron screen (screens of different sizes upon request).

Main structure in round tubular.

5.This machine adopts PLC automatic control, all the operation according to the requirements of the user to set the process parameters automatically, it can print all the process parameters (optional), the original record is true and reliable.

6.Highly polished inner and outer surfaces of the barrel, no dead comer, easy to discharge materials, easy to clear, no cross contamination.

7. The fluid bed granulator have enclosed structure, without overflow of power dust

8. The fluid bed granulators have smooth running, reliable performance, easy operation.

9. The processes of mixing, granulating and drying are completed in one step inside the machine.
