Co-Current Vs. Counter Current Drying

Co-current or parallel flow drying occurs when the drying air flows in the same direction as the material, or rather, when the material and process gas enter the dryer at the same end of the drum, as shown in the illustration below.

Scrubbers Selection Guide: Types Features Applications ...

Dry spray absorbers are packed towers where the gases are contacted with an atomized alkaline slurry. Acid gases form solid salts which can then be removed in the system's particulate control device. Spray dryers can achieve acid gas removal efficiencies above 80%. ... In co-current flow, the scrubber liquid and gas flow in the same direction ...

Problems and solutions - Spray Dry Nozzles CLICKDRY ...

Mar 21, 2022 Solution: Flat Cap Profile. ClickDry flat cap design provides a lower outer face profile, which greatly reduces bearding. This means fewer dryers shut down for clean-up and, therefore, higher productivity. If we reduce build-up, we slow the bearding process and then nozzles can run longer. The ClickDry system offers longer run times.

The objective of this paper is to study the flow patterns in a co-current spray dryer and to study the effect of change of the cylindrical height and diameter on flow patterns inside the dryer. ......

Spray-type dryer of counter-current swirl flow with inert ...

The spray-type dryer with counter-current swirl flows having inert carrier consists of a cylindrical body with, at least, two tangential nozzles for coolant supply. The pneumatic injectors for solution supply to the inert carrier bed are located in the above nozzles. The central gas line is intended for the spent coolant removal above the gas ...

(PDF) Spray Drying Yakindra Timilsena - Academia.edu

There are four fundamental steps involved in spray drying (Broadhead et al., 1992; Filkova et al., 2006): (1) Atomization of a liquid feed into fine droplets, (2) Droplet-hot air contact (3) Evaporation of droplet water and (4) Recovery of the powder. In addition, the feedstock is normally concentrated prior to introduction into the spray dryer.

CFD Simulations of a Co-current Spray Dryer

This paper presents the prediction of air flow, humidity and temperature patterns in a co-current pilot plant spray dryer fitted with a pressure nozzle using a three dimensional model. The modelling was done with a Computational Fluid Dynamic package (Fluent 6.3), in which the gas phase is modelled as continuum using the Euler approach and the droplet/ particle phase is …

SPRAY DRYING -

Types of spray dryer systems On the basis of the type of flow Co-current flow dryer In the co-current flow dryer, the spray is directed into the hot air entering the dryer and both pass through the chamber in the same direction. Spray evaporation is rapid and the temperature of the drying air is quickly reduced by the vaporization of water.

Unsteady RANS and detached eddy simulation of the multiphase flow in a co-current spray drying ... The DES simulation also confirmed the presence of anisotropic turbulent flow in the spray dryer from the analysis of the velocity component fluctuations and turbulent structure as illustrated by the Q-criterion.

GEA spray drying - GEA engineering for a better world

When operating in co-current mode, the nozzle tip is placed close to the outlet of the ceiling air disperser. The co-current mode is selected when drying heat-sensitive products. When coarse particles of a non-heat-sensitive feed are required, the two-fluid nozzle in fountain mode is appropriate. Pressure nozzle, co-current or fountain mode

Rotary Dryer - Manufacturer of Spray Dryers Flash Dryers ...

When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow).
