A process for the production of short cooking time rice is characterized by that hulled rice of at least 10% moisture content, if required in packaging suitable for ready cooking, is heat treated for 1 to 30 minutes continuously or interrupted by equal or alternating capacity microwave radiation, to reach maximum 130&#xb0; C. An apparatus for the production of short cooking time rice has a microwave furnace with a tunnel made from a suitable material, wherein the rice packed into packages is movable within the tunnel by a conveyor. Regarding the easy and short process, a remarkable energy saving is possible.

Process and apparatus for the production of short cooking time rice

The invention relates to an improved method for the preparation of a 2',6'-dialkyl-N-alkoxymethyl-2-chloro-acetanilide compound of the general formula (I), ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are identical or different and stand for straight-chained or branched C.sub.1-4 alkyl groups. According to the invention a dialkyl aniline of the general formula (II), ##STR2## wherein R.sub.1 and R.sub.2 are as defined above, is treated with aqueous formaldehyde solution in an apolar solvent at a temperature of 30.degree. to 80.degree. C., the solution of the resulting oxymethyl derivative formed with said apolar solvent is separated from the aqueous formaldehyde solution at an elevated temperature and then dehydrated, the resulting azomethine derivative is reacted with chloroacetyl chloride in the same apolar solvent medium, the resulting chloromethyl compound is reacted with an alcohol of the general formula (V),
