FLUID BED THERMAL PHYSICAL PROCESS TECHNOLOGY

Fluid Bed dryer for bioplastics FLUIDIZATION In a Fluid Bed, a product or solid is made fluid by an upwardmoving flow of gas. The mechanical movement of the Fluid Bed strengthens this effect. Thus the gas and product are intensively mixed, so that high heat transfer and an optimum physical reaction speed are achieved. By choosing a good combination of gas speed and mechanical movement (if necessary), you can process granular products with a wide range of grain sizes successfully while forming a minimum amount of dust. Both the static and mechanical Ventilex Fluid Bed can function at...

SUB-FLUIDIZATION Longitudinal mixing occurs during the fluidization process. As a result, if the process time is long, the difference in residence time of the individual particles is too great. This can lead to damage to the product. Yet there are products that require long processing. So this would have to occur in a Fluid Bed with a very high length to width ratio. This is usually not desirable, among other things because it takes up too much space. Our solution for this problem is sub-fluidization. In this process, the product remains on the verge of fluidization. Our unique drive...

FLUID BED Each product has its own, specific characteristics. By means of careful testing in our laboratory, we determine the most effective and efficient processing method. The installation is then designed and built internally by Ventilex. As the diagrams show, there are several versions of the air supply system, the Fluid Bed and the flue/discharged gas system. They can be combined in different ways. Ventilator/Fan in combination with heat exchangers 1c/d Ventilator/Fan in combination with direct burner (gas / oil) 1e Ventilator/Fan in combination with indirect burner (gas / oil) Fluid...

Fluid Bed dryer/cooler for cereals APPLICATIONS The Food, Diary and Nutraceuticals industries process the following products among others in a Ventilex Fluid Bed: beta carotene rice salt calcium gluconate lactitol, sorbitol, xylitol sausage farce (rusk) licorice extrudate cocoa beans potato flakes tomato pulp powdered milk

FOOD, DAIRY AND NUTRACEUTICALS Within the Food, Diary and Nutraceuticals industries, the Fluid Bed is applied for: - derivates. - supplements. - ingredients. - end products. A whole range of products can be processed in the Fluid Bed and sub-Fluid Bed and long residence times, up to two hours per machine, are possible. Our unique drive provides an ideal plug-flow. SPECIFIC CHARACTERISTICS/ADVANTAGES Naturally hygiene has top priority in the food industry. The sanitary design (FDA/USDA-GMP) ensures that our installations Fluid Bed dryer/cooler for vitamins meet the high requirements of this...

BIOMASS, ANIMAL FEED AND INORGANIC WASTE It is possible by means of Fluid Bed processing to upgrade waste products and make them suitable for re-use. In this way the environment is burdened as little as possible. SPECIFIC CHARACTERISTICS/ADVANTAGES This industry will often have to deal with a product in which the size of the individual particles differ greatly from each other and the humidity is high. The Ventilex Fluid Bed guarantees a high evaporation rate at low temperatures and low energy consumption. Our unique drive ensures that we can make the Fluid Bed as big as the product...

Fluid Bed dryer for bioplastics

sand-drying installation under construction APPLICATIONS In the mineral industry, the Ventilex Fluid Bed is used to process among others the following products: aggregates blast furnace slag iron slag calcium carbonate marble sand china clay non-ferrous metals copper slag rock salt ferrous metals

MINERALS To process these products a strong, solid installation is needed. The Ventilex Fluid Bed systems are therefore durable and corrosion-resistant. SPECIFIC CHARACTERISTICS/ADVANTAGES For this industry it is important to be able to work at high temperatures. In the Ventilex Fluid Bed temperatures up to 600ºC can be achieved. Efficient consumption of energy is possible due to heat recuperation/recovery from the flue/discharged gases. In addition, the Fluid Bed can be divided into different compartments. In this way it is possible to dry and cool (evaporative) within a single...

CHEMICALS To process chemical products, Ventilex offers total solutions with the right flue/discharged gas systems. They have been designed specially for the chemical industry. SPECIFIC CHARACTERISTICS/ADVANTAGES Naturally the Ventilex Fluid Bed installations are corrosionresistant. What is more, we use various materials such as titanium, hastelloy, duplex and superduplex, depending on the properties of the product to be processed. APPLICATIONS In the chemical industry, the Ventilex Fluid Bed is used to process among others the following products: static Fluid Bed dryer/cooler for KNO 3...

Fluid Bed dryer/cooler for aramide Fluid Bed cooler for detergent powder

SPECIALS As described, Ventilex designs client-specific solutions with various combinations of the air supply system, the Fluid Bed and the flue/discharged gas system. But we have even more to offer: the ‘specials’. 3 A FEW EXAMPLES ARE: 1 Batch dryer with integrated filter. This batch dryer is used for products that require a high processing temperature or different temperature phases. 2 Steam treatment system for food in combination with a Fluid Bed dryer/cooler. 3 Combination of a Fluid Bed baking oven and a Fluid Bed dryer/cooler.

laboratory test installation VENTILEX TEST FACILITIES In our laboratory, we can simulate processes with varying parameters and thus determine the best possible product processing. This is necessary for many processes to prevent damage to the product. Samples can be subjected to tests at temperatures up to 600°C. After carefully analysis of the results, each installation is custom designed and manufactured.
