PROCEDURE FOR THE SOLIDIFICATION FROM TEILCHENFOERMIGEN SOLIDS AND CLEANING PRODUCTS

PROCESS FOR CONSOLIDATING PARTICULATE SOLIDS AND CLEANING PRODUCTS THEREFROM

A bed of particulate solids including some hydrated materials can be converted by controlled irradiation with subinfrared electromagnetic radiation into a unitary porous solid that is mechanically strong enough for easy handling. When the particulate solids include typical acid to alkaline cleaner materials, a block or tablet especially suitable for automatic cleaning machinery, with a very fast dissolution rate in water, can readily be obtained.

PROCESS FOR CONSOLIDATING PARTICULATE SOLIDS AND CLEANING PRODUCTS THEREFROM

A process for the formation of a unitary solid from a bed of particulate matter by (A) providing a container with walls penetrable by subinfrared electromagnet ic radiation and having within the container a bed of particles of raw material , at least part of said raw material being a hydrated material; (B) irradiating the bed of particles in step (A) for a sufficient time with subinfrared electromagnetic radiation to cause the temperature of at least part of the raw material to rise, and subsequently discontinuing the irradiation of raw material and cooling it, so as to transform the bed of particles into a macrosolid within the container and wherein the macrosolid has a bulk volume that is not greater than 1.20 times the bulk volume of the particle bed from which it was formed.

Automatisiertes Laborgerät

A laboratory appliance for carrying out chemical reactions, in particular for analytical applications, has a flask (1) for the used substance surmounted by a reflux condenser (2). A funnel (7) whose neck end (10) is laterally guided towards the inner wall (11) is inserted in the condenser. In addition, a dispenser automatically adds liquids into the flask (1) and a micro-wave oven heats the material contained in the flask (1). The neck end (10) of the funnel (7) extends so much downwards that the inner wall located below the neck end (10), in the area of liquid discharge, forms a smooth surface with no projections nor recesses. The advantages of an automated micro-wave laboratory system can thus be used for the analysis of a large number of samples, at the same time as the required reliability and precision of the results of the analysis are ensured.
