Precision Machinists supplies synthetic Detergent Plants for Powder, Cake and liquid soap.


1. Detergent Cake Plant

The Basic process comprises of all the raw materials being added into a mixer as per the sequence of the formulation and mixed till the reaction is complete. The mass is then extruded into bar or cake depending on the shape and size using plodder.
The equipment needed for a detergent cake are as follows:
Sigma Mixer
Plodder
Lump Breaker
Cutting with Embossing Machines
Belt Conveyor

2. Dry Mix Detergent Powder Plant

The dry mix process is recommended when a medium bulk density powder detergent is required. The Basic process comprises of all the raw materials being added into a mixer as per the sequence of the formulation. The mixer used depends on the characteristics and moisture of the final product. The advantage of this process to produce detergent powder, compared to the more traditional spray drying process, is the almost total elimination of fuel cost for water evaporation. The powder is the taken for sieving and then packed into the require packing.
The different type of Mixer used are:
Sigma Mixer
Roto Mixer
Ribbon Blender
For sieving a cage mill or a vibratory sieve is used
Plough share Mixer

3. Spray Drying Detergent Powder Plant

The spray drying process is used where a low bulk density powder detergent is required. The Neutralised sulphonic acid and other raw materials are thoroughly mixed in a slurry preparatory. The slurry thus formed is then filtered. The slurry is sprayed from the top of a tower, to form very thin droplets because of High pressure. As the droplets of the slurry fall from the top they come in contact with a stream of hot air. Some of the water gets evaporated and the droplet then forms a small hollow hard shells called "beads". The finished product is then stored and cooled in air lift from where it is taken to a packing machine where it is then packed into the required packing.


4. Liquid Detergent Plant

Precision Machinists supply equipment to produce liquid detergents for personal care and house hold products.

6. Batch Sulphonation Plant Using Sulphuric Acid/Oleum

Sulphonation Plant : In this process organic material like LAB/DDB is Sulphonated by Using Oleum and/or sulphuric acid as sulphonating agent, sulphonation is completed in a single agitated vessel called sulphonator. This vessel also acts as a dilutor and a separator to give final sulphonic acid and spent acid, cooling coils are provided to maintain the temperature. Such plants require less investment and are ideal for small capacities.


7. Continuous Sulphonation using Sulphuric Acid/Oleum

In this process organic material like LAB/DDB is sulphonated by Sulphuric acid and/or oleum .The process of sulphonation is completed by using various equipments like sulphonator, Dilutor, and a separator. This is a continues process where by the raw materials are fed continuously by means of dosing pump and the final products like sulphonic acid, spent acid are also discharged continuously. Such a plant is ideal for medium as well as large capacity.


8. Continuous Sulphonation by Cascade Reactor

In this sulphonation is carried out by using a mixture of SO3 and dry air. The SO3 gas can be obtained either by Oleum stripping or vaporization of liquid SO3 or by sulphur burning. Main equipments like Cascade reactor, Air generator, Air drier, Scrubber system, Electronic precipitators (ESP) and equipment for SO3 generation are used for this process. Additional equipments like Heat exchanger and vaporizer are required for oleum stripping/liquid furnace, SO2 cooler, SO2- SO3 convertor, SO3 cooler and SO3 filter are used. This process is ideal for medium to large capacities and requires fairly high investment. Moreover the quality of sulphonic acid produced by this method is better than the above two process.


9. Continuous Sulphonation using Sulphur Burning

The basic process of sulphonation is similar to that of cascade reactor. This is a continuous process and sulphonation is carried out by a film reactor instead of a cascade reactor. The quality and the colour of sulphonic acid produced by this method is very much superior than any other process. Another advantage of this process is that it can sulphonate various organic material like linear Alkyl Benzene, Alpha olefin, Methylesters etc. This process is ideal for large capacities and requires a high investment.
