TH7489B - A process for preparing a granular detergent component with a high overall density. - Google Patents

Abstract

Components or components of a granular detergent with a minimum overall density of 650 g / l Can be prepared by The action on the substrate particles is as follows: (1) In the first step in the high-speed high-density mixer / concentrator. The time interval that remains on the machine is approximately 5 to 30 seconds (2). In the second step. In a medium-speed granulator / denseizer, which can be introduced into or maintained in The deformable state, the time remaining in the machine is approximately 1 to 10 seconds (3) in the final step. In the drier And / or coolers, preferably to bring the precursor particles in a transformed state into step one.

Claims (9)

1. Process for preparing components Or a granular detergent component with a total density of at least 650 grams per liter It consists of the following actions on the precursor particles (1) in the first step in the mixer / density apparatus. Increased high speed type The time interval that remains on the machine is approximately 5 to 30 seconds (2). In the second step. In a medium-speed granulator / denseizer, which can be introduced into or maintained in The state is transformed, the time remaining in the machine is approximately 1 to 10 seconds (3) at the last step. In the drier And / or coolers 2. Process as previously claimed in claim 1, the precursor particles are introduced into or preserved in State that transforms shape in one step 3. The process as previously claimed in claim 1 or 2, the time remaining in the machine in the second step is approximately 2-5 minutes. 4. Process for which the claim has been made in the clause Any one of items 1 to 3 prepares a deformable state at a temperature above 45 ํ C and / or the addition of liquid to the substrate particles. 5.
