Abstract
The invention is a process for manufacturing granules of a washing or cleaning agent from an at least partly solid mixture of granules by admixing plasticizers or lubricants with the granules and passing the mixture through a mixing zone at an elevated temperature and pressure to form a plastic flowable material and passing the plastic flowable material through a plurality of orifices of small diameter and cutting the extruded material at predetermined lengths to form a particulate washing or cleaning agent.
Claims30
A process for the production of a granulated detergent product from a mixture of at least partly solid fine particles which comprises:
- adding at least one additive selected from the group consisting of plasticizers and lubricants to the mixture to form a particulate free flowing premix extruding the premix containing the additive in an extruder under a pressure of at least 25 bar through a plurality of bores (6) which have an inlet-end zone (7) of a relatively large diameter and an outlet-end zone (8) of a smaller diameter, a length-to-diameter ratio in the inlet-end zone (7) being between 1.5 :1 and 6:1 and, a length-to-diameter ratio in the outlet-end zone (8), being between 0.3:1 and 2:1 and cutting the issuing strands transversely to a predetermined length immediately after leaving the bores.
