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

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 |

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.

We also give Sulphonation plant to manufacture surfactants for use in detergent Product
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.

Such plants require less investment and are ideal for small capacities.
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.
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.
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.
