1 Introduction

Most

electric

cookers

on

today's

market

heat

up

with

the

selection

of

mechanical

mode

or

rated

power

mode

in

which

low

energy

utilization

and

single

function

fail

to

meet

people's

ever-increasing

living

demand.

In

such

circumstances,

it

becomes

extremely

necessary

to

develop

one

kind

of

intelligent electric cooker with multifunction, safety and reliability. It has gone

through many stages for mechanical electric cookers to develop into intelligent

ones. Three major types including microcomputer, computer and machine with

ten

different

patterns

have

come

into

being

due

to

the

predominant

hi-technology

being

applied

in

electric

cookers;

besides,

they

turn

to

be

more

diversiform and fashionable on the basis of nice cooking. Apart from low price,

the

mechanical

electric

cookers

barely

satisfy

people's

demand

for

modern

or

high-quality

living,

while

the

intelligent

ones

being

controlled

by

microcomputer

or

computer

succeed

with

the

following

characteristics:

The

man-oriented

interface

design

enables

users

to

notice

the

operating

state

easefully; the whole cooking procedure is automatically controlled by computer;

moreover,

outer-space

crystal

is

taken

as

the

inner

pot

for

its

super

hardness,

outstanding

abrasion-resistant

durability

and

everlasting

handsomeness. All the features match the modern concept of time saving, labor

saving and durability.

The

intelligent

electric

cookers

have

the

following

functions:

normal,

fast,

warming,

small

quantity

cooking,

45-min

gruel,

2h

porridge,

1h

soup

and

2h

soup; moreover, their personalized operation interface makes it easy for users to

control

the

cooking.

With

far

more

capabilities

besides

boiling

rice

only,

the

intelligent

electric cookers have played an indispensable role in

our daily life.

It's the very invention of the intelligent control that makes today's life simpler

and easier.

2 Electric Cooking Procedure

The control of water absorption quantity, heat time, temperature controlling

process, boiling keeping time, temperature keeping process and stewing process

is essential to marvelous cooking. Cooking is a process to convert the β starch to

the more absorbable and digestible α starch. Plenty of practice has

proved that a

perfect cooking procedure can be broken down into the following steps:

·

Water absorption

Make rice absorb as

much water as possible under appropriate temperature so

that

the

cooked

rice

will

look

perfect

and

taste

much

better.

Rice

will

absorb

more water as the temperature rises. However, when the temperature is higher

than

60

℃

,

βstarch

will

be

converted

to

αstarch

and

turned

to

paste.

Thus

it's

necessary

to

control

the

temperature

under

60

℃

.

35

℃

is

considered

to

be

10

optimum and it's better to make the water content of rice amount to about 25%.

·

Heat

Sufficient heat convection is important in heat process to make rice full-cooked.

Generally speaking, the optimum duration from heating to boiling is 10 minutes.

·

Keeping boiling

In order to

makeβstarch fully converted toαstarch, it's advisable to

control

the

temperature

around

98

℃

in

boiling

state

and

boiling

should

last

for

about

20

minutes.

The

temperature

can

be

controlled

by

controlling

the

on

/

off

of

the

relay.

·

Keeping cooking

The temperature falls as the electric cooker is powered off. Remained water in

the pot can be vaporized if electricity is re-supplied for certain period when the

temperature falls to 100

℃

. Duration for keeping cooking may vary according to

your demand.

·

Stewing

After upper procedure is finished, only a little water is left in the pot, here heat

should

be

ceased.

The

remaining

heat

is

enough

to

stew

and

generate

the

digestibleαstarch. The stewing time is generally kept for 12 minutes.

·

Temperature keeping

When

rice

cooking

is

completed,

the

cooker

will

automatically

enter

temperature keeping mode. Once the temperature is lower than 65

℃

, the heated

plate will heat the pot and the rice is edible.
