TECHNOLOGY
APPLICATION

Spray Drying technology has been designed to obtain base detergent powder, in form of beads of dimensions 0.2 – 2.5 mm, white, without colored spots. The density of the base detergent powder is between 250 – 400 gr/lt and the moisture content 2-6%, depending on the requested formulation, obtained through modulation of slurry composition and drying conditions:

PROCESS
DESCRIPTION

1. Different components are mixed at a temperature between 60 and 80°C.

2. Process water is added according to the slurry formulation and concentration and to its viscosity and pumpability degree. The obtained slurry is atomized in the spray tower at a variable pressure between 30 and 60 atm.

3. Water is evaporated and extracted from the droplets by a hot air stream at a temperature about 250 – 450°C. On the spray tower bottom, the base powder is extracted by means of a conveyor belt and cooled by an air lift.

4. At this point the base powder is enriched with requested additives which cannot be treated in the spray tower or packed directly.

5. Formulations for hand washing and washing machine products are standard but Marsina Engineering is ready to assist its Clients in defining alternative formulas according to specific market requirements.

CONTROL
SYSTEM

The plant functions are automatic to minimize the number of necessary operators.

Slurry preparation is batch-wise while spray drying process is continuous. All operations are controlled and regulated by advanced PLC system and various local control panels, guiding the plant in accordance to formulate the desired recipes.
