Definitions
- the present invention generally relates to a non-tower process for producing a particulate detergent composition. More particularly, the invention is directed to a continuous process during which detergent agglomerates are produced by feeding a surfactant and coating materials into a series of mixers. The process produces a free flowing, detergent composition whose density can be adjusted for wide range of consumer needs, and which can be commercially sold.
- the first type of process involves spray- drying an aqueous detergent slurry in a spray-drying tower to produce highly porous detergent granules (e.g., tower process for low density detergent compositions).
- the various detergent components are dry mixed after which they are agglomerated with a binder such as a nonionic or anionic surfactant, to produce high density detergent compositions (e.g., agglomeration process for high density detergent compositions).
- a binder such as a nonionic or anionic surfactant
- the Laid-open No.WO93/23,523 (Henkel) describes the process comprising pre-agglomeration by a low speed mixer and further agglomeration step by high speed mixer for obtaining high density detergent composition with less than 25 wt % of the granules having a diameter over 2 mm.
- the U.S. Patent No. 4,427,417 (Korex) describes continuous process for agglomeration which reduces caking and oversized agglomerates.
- the present invention meets the aforementioned needs in the art by providing a process which produces a high density granular detergent composition.
- the present invention also meets the aforementioned needs in the art by providing a process which produces a granular detergent composition for flexibility in the ultimate density of the final composition from agglomeration (e.g., non-tower) process.
- the process does not use the conventional spray drying towers currently which is limited in producing high surfactant loading compositions.
- the process of the present invention is more efficient, economical and flexible with regard to the variety of detergent compositions which can be produced in the process.
- the process is more amenable to environmental concerns in that it does not use spray drying towers which typically emit particulates and volatile organic compounds into the atmosphere.
- agglomerates refers to particles formed by agglomerating raw materials with binder such as surfactants and or inorganic solutions / organic solvents and polymer solutions.
- binder such as surfactants and or inorganic solutions / organic solvents and polymer solutions.
- a process for preparing a granular detergent composition having a density at least about 600 g/l comprises the steps of:
- granular detergent compositions having a high density of at least about 600g/l, produced by any one of the process embodiments described herein.
- the present invention is directed to a process which produces free flowing, granular detergent agglomerates having a density of at least about 600 g/l.
- the process produces granular detergent agglomerates from an aqueous and/or non-aqueous surfactant which is then coated with fine powder having a diameter from 0.1 to 500 microns, in order to obtain low density granules.
- aqueous and/or non- aqueous surfactant(s) which is/are in the form of powder, paste and/or liquid , and fine powder having a diameter from 0.1 to 500 microns, preferably from about 1 to about 100 microns are fed into a first mixer, so as to make agglomerates.
- a first mixer so as to make agglomerates.
- an internal recycle stream of powder generally having a diameter of about 0.1 to about 300 microns, which can be generated from an "optional conditioning process (i.e., drying and/or cooling step)," which is an additional step after the process of present invention can be fed into the mixer in addition to the fine powder.
- the amount of such internal recycle stream of powder can be 0 to about 60 wt% of final product.
- the surfactant(s) can be initially fed into a mixer or pre-mixer (e.g. a conventional screw extruder or other similar mixer) prior to the above, after which the mixed detergent materials are fed into the first step mixer as described herein for agglomeration.
- a mixer or pre-mixer e.g. a conventional screw extruder or other similar mixer
- the mean residence time of the first mixer is in range from about 2 to about 50 seconds and tip speed of the first mixer is in range from about 4 m/s to about 25 m/s
- the energy per unit mass of the first mixer (energy condition) is in range from about 0.15 kj/kg to about 7 kj/kg
- the mean residence time of the first mixer is in range from about 5 to about 30 seconds and tip speed of the first mixer is in range from about 6 m/s to about 18 m/s
- the energy per unit mass of the first mixer (energy condition) is in range from about 0.3 kj/kg to about 4 kj/kg
- the mean residence time in the first mixer is in range from about 5 to about 20 seconds and tip speed of the first mixer is in range from about 8 m/s to about 18 m/s

- the examples of the first mixer for the first step can be any types of mixer known to persons skilled in the art, as long as the mixer can maintain the above mentioned condition for the first step.
- An Example can be Lodige CB Mixer manufactured by the Lodige company (Germany).
- agglomerates having fine powder on the surface of the agglomerates are then obtained.
- the resultant (i.e., the first agglomerates) from the first step is fed into a second mixer.
- Finely atomized liquid is sprayed on the agglomerates in the second mixer. If excessive fine powder from the first step is optionally included in the product added to the second step, spraying the finely atomized liquid is useful in order to bind the excessive fine powder onto the agglomerates from the first step.
- About 0-10% , more preferably about 2-5% of powder detergent ingredients of the kind used in the first step and/or other detergent ingredients can be added to the second mixer.
- the mean residence time of the second mixer is in range from about 0.2 to about 5 seconds and tip speed of the second mixer is in range from about 10 m/s to about 30 m/s
- the energy per unit mass (energy condition) of the second mixer is in range from about 0.15 kj/kg to about 5 kj/kg
- the mean residence time of the second mixer is in range from about 0.2 to about 5 seconds and tip speed of the second mixer is in range from about 10 m/s to about 30 m/s

- the examples of the second mixer can be any types of mixer known to persons skilled in the art, as long as the mixer can maintain the above mentioned condition for the second step.
- An Example can be Flexomic Model manufactured by the Schugi company (Netherlands).
- Second agglomerates are then obtained.
- the agglomerates from the second step are fed into a third mixer.
- the second agglomerates are mixed and sheared thoroughly for rounding and growth of the agglomerates in the third mixer.
- about 0-10% more preferably about 2-5% of powder detergent ingredients of the kind used in the first step, second step, and/or other detergent ingredients can be added to the third step.
- choppers which are attachable for the third mixer can be used to break up undesirable oversized agglomerates. Therefore, the process including the third mixer with choppers is useful in order to obtain reduced amount of oversized agglomerates as final products, and such process is one preferred embodiment of the present invention.
- the mean residence time of the third mixer is in range from about 0.5 to about 15 minutes and the energy per unit mass of the third mixer (energy condition) is in range from about 0.15 to about 7 kj/kg, more preferably, the mean residence time of the third mixer is from about 3 to about 6 minutes and the energy per unit mass of the third mixer (energy condition) is in range from about 0.15 to about 4kj/kg.
