Technical Field

The invention belongs to the technical field of instant food, and particularly relates to a preparation method of self-heating rice cold noodles and rice flour.

Background

The cold rice noodles are special food in yuan city of Sichuan province, also called Nhuang steamed cold noodles, only produced in yuan city and peripheral areas, the flavor quality is far away from the production area in the city and is worse, the shape of the cold rice noodles is similar to that of Shaanxi cold noodles, but the raw material is rice rather than flour, the traditional method is that the rice is soaked for 12 hours and then ground into slurry, then the slurry is evenly spread on white cloth and steamed by a special steamer, the cooked rice noodles are taken out and cooled and cut into strips, and the strips are eaten after being evenly mixed with seasonings.

The finished product of the rice cold noodles belongs to high-moisture food, the preservation period at the room temperature of 20 ℃ is within 16 hours, the rice cold noodles can be stored in a refrigerated manner only for 7 days after being packaged in vacuum, the taste is greatly reduced, the conventional production and sale mode of the existing product is adopted at present, and the delicious food cannot be popularized in standard due to the short shelf life and the unsuitability for long-distance transportation.

Chinese patent publication No. CN110140875A discloses self-heating rice cold noodles, which are prepared in a self-heating form, are eaten after being boiled, are not limited by season, time and place of production, and are convenient to carry.

Disclosure of Invention

The invention aims to provide self-heating rice cold noodles and a rice flour preparation method, and the rice flour preparation method is improved, so that the rice cold noodles have better formability and taste.

In order to achieve the purpose, the invention provides the following technical scheme:

the invention provides a preparation method of kinds of rice flour, which comprises the steps of soaking rice in water, grinding the rice into rice milk, drying the rice milk, and grinding the rice milk into powder to obtain the rice flour.

As a preferred technical scheme, the drying temperature of the rice milk is 30-50 ℃.

According to a preferable technical scheme, the grain size of the rice flour is 100-200 meshes.

The invention also provides the rice flour prepared by the preparation method.

The invention also provides self-heating rice cold noodles, which comprise a flour bag, wherein the rice flour is filled in the flour bag.

According to a preferable technical scheme, pea starch is further filled in the flour packet, and the mass ratio of the pea starch to the rice flour is 1: 2-1: 3.

According to a preferable technical scheme, the self-heating rice cold noodle further comprises a seasoning bag and a liquid bottle, wherein water is filled in the liquid bottle, and the mass ratio of rice flour in the powder bag to water in the liquid bottle is 1: 3-1: 4.

As the preferred technical scheme, still include from heat box from heat rice cool noodle, from heat box includes outer box, inside lining and lid, the inside boss that is used for placing the inside lining that is equipped with of outer box, be equipped with the blow vent that is used for water steam to pass through on the inside lining.

As a preferred technical scheme, the number of the inner liners is three, and the three inner liners are sequentially placed in the outer box from top to bottom to form three layers; the shape of the lining is flat, and the upper surface of the lining is provided with separating strips for separating the lining into a plurality of strip-shaped grids.

As the preferable technical proposal, the self-heating rice cold noodle also comprises an edible box.

The invention has the beneficial effects that:

1. the invention firstly soaks the rice with water and then grinds the rice into rice milk, then dries the rice milk and grinds the rice milk into powder to prepare the rice flour, and the rice flour is used as the raw material of the self-heating rice cold noodle, thereby obviously improving the formability of the rice cold noodle and leading the rice cold noodle to have better taste.

2. The invention designs a special self-heating box, which utilizes the vent to ensure that the heated water vapor can rise to the upper space of the rice cold noodle, thereby ensuring that the upper layer and the lower layer of the rice cold noodle can be uniformly heated, and improving the formability of the rice cold noodle by steps.
