Detergent
Powder Plant

Synthetic
detergents, which are also known as syndets, were developed to
overcome the difficulties faced while using soap as a cleaning agent.
Soaps when used in hard water precipitate the calcium and magnesium
salts, due to which it's effectiveness as a cleaning agent
deteriorates.
In
addition, edible oil & fats, which could be put to other uses,
are used as raw materials for the manufacture of soaps. These
problems are circumvented in synthetic detergents that are highly
stable in hard water and do not consume valuable and expensive oil
for their manufacture
Detergent
Slurry Formulation
Detergent
powder falls into four major groups :Heavy
duty detergents (high and low foaming)Light
duty detergentsSoap
powders
Soda
products.
Detergent
formulations essentially consists of :Active
ingredientsSTPPFiller
(e.g. Sodium sulphate)SilicateNormally
active ingredients used for detergents are linear alkyl benzyl
sulphonates.

Spray Drying

Free
flowing, non dusty, non caking detergent products in bead form are
produced by Spray Drying mostly in counter current flow using
pressure nozzle atomization.

Inlet
temperatures vary according to product and upto 400A a A A C inlet
temperatures are used for some detergents. Hot air from direct fired
air heaters is used for Spray Drying. Exhaust high efficiency
cyclones / bag houses are used to control emissions and maximize
product recovery are part of the spray drying plant. RAJ offers stand
alone spray drying plants on turnkey basis

Pneumatic
Conveying, Perfuming & Packing


The
dried detergent powder is pneumatically conveyed from the Spray Dryer
to the product silos after sieving. Here filtered atmospheric air is
used as the cooling & conveying media. Dense phase conveying
systems are normally preferred.

The
detergent product from the silo is then blended along with the
perfume in a continuous mixer after which it is packed.
Applications


Washing
Powders

(Detergents,
Soaps, Surface Active Agents)
The
free-flowing, non-dusty, non-caking products in bead form are
produced in counter-current flow dryers with nozzle atomization is
the preferred layout for high-bulk-density detergents. Feeds are
homogenized and fine-filtered prior to passing to nozzles operating
at high pressure. Hot air from direct-fired air heaters enters at the
base of the cylindrical part of the tower with slight rotary motion.
The exhaust air is drawn from the top of the tower. Inlet
temperatures vary according to product. Up to 400A a A A C
(750A a A A F) is used for some detergents, but lower temperatures
are used for fine washing agents. Product recovery from the drying
tower is high (99%). The fines fraction is usually returned to feed
preparation. Open - cycle dryers are normally used, Co-current dryers
are used for low - bulk - density detergents.

Soda
Products


Detergent
formulations consist basically of (a) an active ingredient (b) sodium
tripolyphosphate, (c) silicates, (d) sodium sulphate. Normally the
active ingredients are primary and secondary alkyl sulphonates and
alkyl aryl sulphonates. Synthetic detergents are currently based upon
linear alkyl benzene sulphonates. Formulations are with variations as
decided by each company.


Heavy
- Duty Detergents


Synthetic
detergents are widely used in cleaning of all types and operate
successfully with hard water. The coarse powder granules in bead form
are free-flowing, non-dusty and readily dissolve in water. Shelf-life
is excellent, with no tendency to instability or lumping. The feed
can be formulated batchwise or continuously. RAJ slurry preparation
systems ensures the right preparation technique which improves the
quality of the final dried detergent powder. Precise weighing /
metering, mixing, homogenizing and de-aeration take place before
spray drying. As high a solid content as possible is used (50 - 65%)
to give the optimum powder bulk density and best economic use of the
spray dryer.

The
product is dried in a counter-current-flow drying tower at inlet
temperature 350 - 400A a A A C (660 - 750A a A A F). The dried
powder leaves the base of the drying tower and is transported via a
conveyor belt to an air lift. During passage on the belt, product
dosing is carried out. Dosing materials can be products that would be
damaged during spray drying, e.g. , enzymes. Bleach alongwith enzymes
is also added at this stage. Perfume is added after the following air
lift.


Light
Duty Detergents


Light
- duty detergents are used less than heavy duty. They find wide
application only in dish washing and light household cleaning
(janitoring). Light -duty detergents are produced in nozzle towers
with either co-current or counter-current flow. Choice depends upon
required bulk density. Inlet drying temperatures are also lower, 250
- 275A a A A C (480 - 530A a A A F).


Detergent
Allied Products


RAJ
also provides state of art powder technology for detergent allied
products like Sodium Lauryl Sulphate (SLS), Alfa Olefin Sulphonate
(AOS), Optical Brightening Agents (OBA), Linear Alkyl Benzyl
Sulphonate (LABSA), Sodium Silicate, Sodium Tri-polyphosphate (STPP).
