Understanding Fluidized Bed Dryers (FBD)

Many industries need to process fluidized, slurries and paste type of materials in such scenarios fluid bed dryer comes in rescue as the traditional dryers such as rotary, tunnel, conveyor, continuous tray not able to provide the desired results. FBD provide advantages such as good solids mixing, high rates of heat and mass transfer and easy material transport over others.

FBD is achieved by passing gas stream from the bottom of a bed of particle to be dried, at low gas velocities the bed is static and the particles rests on gas distributor plate. The fluidizing gas passes through the distributor and it is uniformly distributed across the bed. FBD has upper hand when it comes to drying particle size ranging from 50 to 200 μm compared to other systems. Heat transfer in gas-FBD can be achieved by multiple ways conduction, convention or radiation based on the design and operating conditions. Designing of FBD largely depends on the rate period of the particulates.

Below are the key FBD design parameters:

Dwelling time
Size of Bed
Gas flow rate
Maxx balance
Heat balance

Key application Industries:

Chemical
Food and Beverage
Ceramic
Pharmaceutical
Agriculture products
FMCG
Coating

Different Types of Sterilization Process

Sterilization can be accomplished by an amalgamation of heat, chemicals, irradiation, high pressure and filtration such as steam under pressure, dry heat, ultraviolet radiation, gas vapour sterilants, chlorine dioxide gas etc. Successful sterilization strategies are necessary for working in a lab and negligence of this could lead to severe consequences, it could unexpectedly cost a life. So what are the more frequently utilized methods of sterilization in the laboratory, and how do they work? The Sterilization is conveyed out by the methods according to requirement. The methods are: 1. Moist Heat Sterilization 2. Dry Heat Sterilization 3. Gas Sterilization and Others. Moist Heat Sterilization: Moderate pressure is utilized in steam sterilization. Steam is utilized under pressure as a means of accomplishing an elevated temperature. It is dominant to confirm the accurate quality of steam is utilized in order to keep away the problems which follow, superheating of the steam, f...

Application and Popular Uses of Graphite

Graphite, archaically referred to as plumbago, is a crystalline type of the element carbon with its atoms organized in a very hexagonal structure. It happens naturally during this kind and is the most stable kind of carbon under standard conditions. Under high pressures and temperatures it converts to diamond. Graphite is utilized in pencils and lubricants. It’s a good conductor of heat and electricity. Its high conductivity makes it helpful in electronic product like electrodes, batteries, and solar panels. The principal types of natural graphite, each occurring in different types of ore deposits, are A crystalline small flake of graphite (or flake graphite) occurs as isolated, flat, plate-like particles with hexagonal edges if unbroken. When broken the edges can be irregular or angular; Amorphous graphite: very fine flake graphite is sometimes called amorphous; Lump graphite (or vein graphite) occurs in fissure veins or fractures and appears as massive platy intergrowths of fib...

Heating System with inbuilt Intelligence

Thermal treatment is vital processing step in any kind of product processing systems across various industries such as Pharma, Food, Chemical, Fertilizers, Coating, Paint, Ceramic, Electronics and many more. Application of heating system such as heating, drying, sterilization, coating, pasteurization, blanching, mixing and many more; all requires very preciously controlled heating for quality production. But as we all know, every material put under processing may or may not have the same level of moisture or may not require same temperature for processing though being the same type if material also manually adjusting the heating temperature or heating time is also not feasible; Practically! We as Kerone , have always advocated that the new age thermal treatment systems must be capable of making efficient decision to offer best possible correction based of the input material type its contents and behavior while under processing. This shift is paradigm in...
