Description

A kind of production method of ourishing rice flour

Technical field

The present invention relates to a kind of production method of ourishing rice flour.

Background technology

Along with socioeconomic fast development, the raising of people's living standard and the quickening of rhythm of life, people change the consumption pattern and the consumption habit of rice made products, at safety, local flavor, nutrition, health, aspect such as attractive in appearance, edible and easy to carry higher requirement is arranged, therefore, as the principal item of rice made products, the ground rice industry is just breeding huge development space.

Instant rice-flour is the main food of feeding the infant, also is the essential important semi-fluid accesary foods of many sufferer crowds, elderly population.Cultivate through the markets in surplus ten years, the market demand of China's instant rice-flour product has now reached 30,000 tons, and more than 1.2 hundred million bags (boxes), the instant rice-flour produce market has formed that demand is stable, the huge general layout of development potentiality.But at present domestic enterprise is owing to be subjected to the restriction of traditional processing technology, technology and production equipment, still can't produce smooth evenly laminar, reconstitute the instant rice-flour product that does not lump, do not get angry, adds nutrition accessories such as multiple full price vegetables, fruit after edible.

Summary of the invention

The present invention is directed to the problem that prior art exists, a kind of production method of ourishing rice flour is proposed, by adopting secondary gelatinization, nutrient segmented stream addition and quick dehydration technique, can be under low investment condition, realize high-quality, high efficiency, the automated production cheaply of many kinds serial instant rice flour product.

The invention provides a kind of production method of ourishing rice flour, may further comprise the steps:

A), rice preliminary treatment: will obtain rice end A through rice cleaning, immersion, air-dry, the abrasive dust of selecting;

B), special material is handled: composite nutrient is dropped in its weight 5-10 hot water doubly, stir while dropping into, dissolve fully until nutrient, add water to about 20-40% (weight) of total water amount then, stir, obtain special material B;

C), mix: with rice end A and all other batchings except that composite nutrient that step a) obtains, pour in the pot, open to stir to do and mix;

D), the gelatinization of sizing mixing:

1., give gelatinization: under agitation in step c) gained material, add the hot water of surplus, continue to stir after 10-20 minute, add the special material B that step b) obtains, continue to stir until forming uniform paste mixture;

2., gelatinization: pour the gained paste mixture into adjunce copper, under 60-80 ℃ temperature, continue gelatinization, ready until roller dryer;

E), roller drying: open steam valve logical steam in the roller drier when preparing burden, treat that steam pressure keeps stable, when surface temperature was constant, the material that step d) is obtained was sent into roller and is carried out drying.

Preferred described composite nutrient comprises multivitamin, and is composite by GB 10770 dispensed food for baby requirements.

In a kind of embodiment, described other batching comprises the mixture that selects in white sugar, albumen powder, milk powder, vegetable oil, fruit juice, dish juice, shrimp and the fish gruel one or more.

In a kind of embodiment, the temperature of described hot water is in 70 to 80 ℃ scope.

Preferably, described total water amount is 0.8 to 2.0 times of raw material rice weight.

Preferably, described roller dryer surface temperature is controlled in 130-150 ℃ the scope, and rotating speed is controlled in 900-1150 rev/min the scope.

In a kind of embodiment, the composition of raw materials of described ourishing rice flour is as follows by weight percentage:

Rice: 25.0-50%;

Composite nutrient: 0.75-0.90%;

Other batching: 5-25.0%;

Water: 25.0-50%.

The production method of preferred described ourishing rice flour is further comprising the steps of:

F), pulverize and sieve: the step e) products obtained therefrom is ground into uniform small pieces by the conveyer belt type rotation cutting knife of turning over, removes large stretch of through the 0.38cm screen cloth.

The present invention adopts secondary gelatinization, nutrient segmented stream addition and quick dehydration technique, can be under low investment condition, realize high-quality, high efficiency, the automated production cheaply of many kinds serial instant rice flour product.And the ourishing rice flour of producing with the inventive method is smooth laminar uniformly, have rehydration strong, reconstitute and do not lump and advantage such as easily digest and assimilate.In addition, the present invention adopts the nutrient formulation aim at the Chinese Infant and Children design, the infant edible for a long time not hot dry, " do not get angry ", nutrition arrangement is rationally balanced, is more suitable for infants.
