Abstract
A process for continuously cooking rice by steaming comprises the steps of continuously feeding steeped rice into a vertical steamer, promoting the gelatinization of the rice by gradually heating the rice packed in the steamer with jets of steam, cooking and hydrating the heated rice by discharging it from the steamer and passing it through a bath of hot water for heating, transferring the cooked, hydrated rice onto a net conveyor, and then finish-steaming the rice being conveyed by subjecting it to jets of steam.
Claims7
A process for continuously cooking rice by steaming which comprises steps of:
- (a) continuously feeding steeped rice into a vertical steamer;
- (b) promoting the gelatinization of the rice by gradually heating the rice in said steamer with jets of steam;
- (c) cooking and hydrating the heated rice by discharging the heated rice from said steamer and passing it through a bath containing hot water at a temperature of 60.degree. C. to 100.degree. C.;
- (d) transferring the cooked, hydrated rice onto a net conveyor;
- and
- (e) then finish-steaming the rice being conveyed by the net conveyor by subjecting the cooked, hydrated rice to jets of steam at a temperature of at least 101.degree. C.
An apparatus for continuously cooking rice by steaming comprising:
- (a) a vertical steamer having steam outlets directed inside the vertical steamer for providing steam to heat steeped rice continuously fed to the vertical steamer for promotion of the gelatinization thereof with steam issued from said steam outlets;
- (b) means for leveling the steamed rice to a layer of a given thickness and conveying it at a predetermined rate into a hot water bath;
- (c) said hot water bath for cooking and hydrating the leveled rice from said vertical steamer by dipping the rice in water at 60.degree. C. to 100.degree. C. within the bath;
- (d) a net conveyor for carrying the rice from said hot water bath;
- and
- (e) a finish-steaming chamber including a bank of steam injecting nozzles for cooking with steam at a temperature of at least 101.degree. C. the rice being carried by said net conveyor.
