The process of manufacture of Detergents broadly involves neutralizing LABSA (Acid Slurry)
with Alkali and maintain the PH at desired level by blending the same with different
additives like optical brightening agent and other soluble and insoluble builders and
perfume to enhance the cosmetic value.
For the manufacture of Detergent Powder two processes are adopted. These are wet process and
dry process. Keeping an eye on cost effectiveness vis-a-vis quality of the products dry
mixing process is widely in use for the manufacture of Popular and Economy Grade Detergent
Powder. Process of manufacture of Detergent Powder by dry mixing process are broadly divided
into three stages.
These three stages can be manually done which is very primitive and do not give consistent quality outputs. By use of machines for different operations and material conveying systems there will be consistency in quality resulting in reduction in cost, increase in quantity of production with moderate profit generation.
This is the stage where the requisite raw materials are prepared for
blending. Physically there are two types of raw materials i.e. dry raw materials in powder
form and liquid raw materials. Different dry raw materials of required quantity are sieved
in a vibratory screen so that any lump bigger than the desired particle size is discarded.
These are however recharged to the screen after grinding.
The liquid raw materials of desired quantity are fed to a tank provided with a stirrer.
These are stirred till a homogenous mix is formed.
This stage involved through blending of different materials. The powdered materials from
vibratory screen are fed to a specially designed Mixer through a Bucket Elevator. The liquid
mixture from the tank is also pumped to the Mixer.
These are mixed in batches. Time of blending is pre-determined in the Laboratory. The
materials are converted into a free flowing uniform looking mass.
The Detergent Powder after being unloaded from the Mixer is transferred to a Silo and
through screw feeder it is transferred to Cage Mill for homogeneous mixing and braking the
lumps if any formed in the mixing stage. From Cage mill the powder is transferred through
bucket Elevator to the final sieve before it is transferred to the packing section.
The packing involve two operations such as (i) Pouch Packing and (ii) Outer Packing. Pouch
Packing for retail sale whereas Outer Packing in H.D.P.E. Woven Sacks is done for wholesale
marketing.
The Powder which passes through the Vibratory Screen travel through drag conveyor and
distributed to the Silos of FFS machine through vibro sieve. The weigh metric Automatic
Packing Machines are adjusted to pack various pack sizes depending on the trade requirement.
The packs are then transferred for Bulk Packing in H.D.P.E Woven.Sacks through a Belt
Conveyor and stacking is done at the ware house where the set norms for checking are done by
Quality Assurance Department before the same is cleared for dispatch.
