Description

Control method of rice cooker

Technical Field

The invention relates to the field of kitchen appliances, in particular to a rice cooker and a control method thereof.

Background

In order to realize the production of low-sugar rice, the existing part of rice cooker is provided with a water outlet on the liner, and an electromagnetic valve is arranged at the position of the water outlet to drain water, so that the liner has a complex structure and high cost, and an independent water storage box is arranged outside the liner, so that users are inconvenient to use and difficult to clean.

The rice cooker is characterized in that a steamer is arranged in a part of the rice cooker, water holes are formed in the steamer, rice is placed in the steamer, when the rice cooker works initially, water in the inner container enters the steamer through the water holes in the steamer and floods the rice, as the rice cooker works, the heating element continuously heats the inner container, the water level in the inner container is gradually reduced in the continuous heating and boiling process, and in order to realize the great reduction of the water level to manufacture low-sugar rice, the heating element is required to continuously heat, so that the long-time boiling of the rice in the water can realize the reduction of the water level, a user can not accurately grasp the water level of the added water and the matching height of the water level and the rice in actual use, so that the quick complete separation of the rice and the rice can not be realized, the manufactured low-sugar rice is softer, has poor taste and has poor effect of reducing starch and sugar; when the user is making low-sugar rice, the water is too much, or the rice is too much, the water in the inner container and the rice can not be completely separated, so that the taste of the low-sugar rice is poor, the starch and sugar content reducing effect is poor, and the low-sugar rice can be made only by strictly limiting the height of the water level and the matching height of the water level and the rice.

The rice cooker is characterized in that a water storage box is arranged in the rice cooker, a small amount of rice soup in the inner container enters the water storage box in a overflowing manner in a narrow space in the working process of the rice cooker by strictly limiting the heights of the water storage box and the bottom surface of the inner container, but the method ensures that most of rice soup is left at the bottom of the inner container and cooked together with rice to form low-sugar rice, and the scheme also needs to strictly limit the height of the water level.

Specifically, one set of experimental data of the low-sugar rice prepared by the scheme is as follows:

experimental conditions: the food material is rice, and the starch content is 76.1g starch (the source of the value 76.1 is the data mark of carbohydrate in the nutrient composition table on the rice packaging bag) in every 100g rice; the test uses 200g rice and 1800g clean water;

The calculation method comprises the following steps: after the low-sugar rice is manufactured, placing rice soup at the bottom of the liner 2 and rice soup in the rice soup collecting box 4 into a beaker together, placing the beaker into an oven for baking, and testing the weight of the solid residue after the moisture is completely evaporated;

the weight of the solid residue is A, wherein the average value of the starch content in the solid residue is 97.54 percent (the numerical value 97.54 percent is derived from the influence of rice digestion and dissolution starch on the rice texture and the electrochemical evaluation of the rice texture are described in paper 42, the chemical composition analysis in 3.41 sections of rice soup is that the solid in the rice soup mainly comprises starch composition (97.54 percent), and trace protein, fat and ash, and the weight of the starch contained in the solid residue is (A multiplied by 97.54 percent) g;

the calculation process comprises the following steps: the total starch weight in the rice of this experiment was 200g×76.1% = 152.2g; the starch content in the solid residue of the discharged rice soup is (a× 97.54%)/152.2 g;

settlement results: in the test data, when the solid residue in the beaker after baking is 12.8g, the weight of the starch contained in the rice water is 12.8x 97.54% =12.48 g, (12.48/152.2) ×100% =8.2%. The starch content of the low-sugar rice manufactured at this time reaches 8.2 percent.

Based on the experimental calculation results, compared with the prior art that the method for manufacturing the low-sugar rice by adopting the method of strictly limiting the water level and adopting the heating piece 5 to continuously heat to realize the slow reduction of the water level of the rice soup in the liner 2, the starch content of the low-sugar rice is obviously improved by about 3.5 percent; compared with the prior art, the method for preparing the low-sugar rice by strictly limiting the heights of the water storage box and the bottom surface of the liner 2 to realize that part of rice soup overflows into the water storage box has the advantage that the starch content of the low-sugar rice is remarkably improved by about 4 percent.

Based on the experimental calculation results, the rice cooker and the control method thereof realize complete separation of rice soup and rice, have better starch content reducing effect, obtain remarkable improvement, and actually test that the low-sugar rice has better taste, mainly the rice is independently steamed on the steaming piece 3, the hardness of the rice is moderate and adjustable, and the problem of softness does not occur. Solves the problems that the prior rice cooker can not realize the complete separation of rice soup and rice, resulting in poor effect of reducing starch content, softer low-sugar rice and poor taste.

The specific advantage, this scheme sets up the water storage box and through the high of strict limitation water storage box and inner bag bottom surface inside current rice cooker, realizes the mode that makes low sugar rice through entering into the water storage box in the mode that overflows in narrow space in the rice cooker work in-process inner bag a small amount of rice soup has: the rice soup and the rice soup can be quickly and completely separated, the problem that the rice soup and the rice are not completely separated in the rice cooked by the rice soup at the bottom of the liner and the rice, the rice soup and the rice are quickly and completely separated, the effect of reducing the starch content in the rice is better, and the taste of the rice is better; the height of the water level of the liner is not required to be strictly limited, and the matching height of the water level and the rice is not required; compared with the prior art, the mode that the steamer is arranged inside the rice cooker and the water level in the liner is gradually reduced by the continuous heating and boiling process has the advantages that: can realize that rice and rice soup are quick complete separation, can not appear making the slow problem that descends of water level that utilizes the heating, can not appear that the rice is soft excessively, the taste is poor in the long-time boiling of rice in rice soup, and need not to restrict the water level height of inner bag and the matching height of water level and rice strictly, reduce the starch content effect in the rice better, and the rice taste is better.

Aiming at making low-sugar rice, water and partial starch in the rice are separated into water in the process of fully boiling the rice to form rice soup, the rice soup is in a thick and pasty state, the rice soup contains more starch, the rice soup is fully gushed under the condition that the heating element 5 is continuously heated, and the rice soup is more quickly gushed upwards and is easier to gush upwards due to the high concentration of the rice soup; at the same time, the rice soup is easy to be formed to be upwards gushed, one part of the rice soup is formed to be upwards gushed, and the rice soup is taken away by the rice soup to be upwards gushed together, so that more rice soup can quickly enter the rice soup collecting box 4, most of the rice soup in the liner 2 can be ensured to be upwards gushed to enter the rice soup collecting box 4 in the step S2, so that rice soup left in the bottom of the liner 2 can not submerge rice on the steaming piece 3, and the rice soup is completely separated from rice; therefore, the rice cooker can be better applied to the preparation of low-sugar rice, the problem that the rice and the rice soup are mixed and boiled for a long time to reduce the rice soup position in the liner 2 can be avoided, the taste of the low-sugar rice can be improved, and particularly the hardness and the taste of the low-sugar rice can be improved.
