Coarse cereal milk and preparation method thereof

Abstract

The invention discloses a preparation method of coarse cereal milk. The preparation method comprises the following steps: mixing materials, preheating a material blending jar, and putting coarse cereal powder, a stabilizer, white granulated sugar and water into the material blending jar to be mixed so as to obtain coarse cereal liquid; performing gelatinization: when a tubular heat exchanger is preheated to 75-95 DEG C, injecting the obtained coarse cereal liquid into the tubular heat exchanger to be heated, wherein the time of the coarse cereal liquid flowing through the tubular heat exchanger is 10-15 min, and obtaining coarse cereal pulp; performing primary homogenization, and further dispersing the obtained coarse cereal pulp through a colloid mill; performing cooling; enabling the volume to be constant; performing stirring; performing homogenizing; and performing sterilizing and filling to obtain the coarse cereal milk. The method has the advantages that by controlling the temperature of the tubular heat exchanger and the flowing time of liquid, the online dynamic gelatinization process of high-starch material liquid is achieved, the gelatinization is achieved in the materialliquid flowing heat exchange process, the gelatinization time in a jar body is saved, and besides, production energy consumption is reduced; and since gelatinization in the jar body is not adopted, continuous material blending can be realized, and the production time is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of dairy product processing, in particular to miscellaneous grain milk and a preparation method thereof. Background technique [0002] Miscellaneous grains refer to the general term for various grains, soybeans and potatoes with a relatively small planting area except rice, wheat, corn and soybeans and other bulk grains. Our country is rich in miscellaneous grain resources and there are many varieties, which can be roughly divided into four categories: one is miscellaneous grains, such as sorghum, millet, buckwheat, barley, millet, etc.; the other is miscellaneous beans, such as mung beans, kidney beans, red beans, peas, Black beans, etc.; the third category is potatoes, mainly potatoes and sweet potatoes; the fourth category is oil plants, such as sesame, mustard, perilla, oil sunflower, walnuts, etc. [0003] At present, people are paying more and more attention to healthy diet, and miscellaneous grains a...

Problems solved by technology

[0003] At present, people are paying more and more attention to healthy diet, and miscellaneous grains are made into multigrain milk for people to drink because they are rich in protein, vitamins, minerals and various functional factors; however, in the actual large-scale production of multigrain milk, due to the starch content of multigrain powder Higher, when the addition amount reaches a certain value, it is necessary to add a gelatinization process in the preparation process, but the conventional gelatinization process is to keep the temperature longer in the batching tank at a higher temperature when the water and powder reach a certain ratio. Time, after completing the gelatinization process, enter the next process, thus increasing the production energy consumption;

[0004] In addition, since the volume of the batching tank is much smaller than the actual production volume, and the ratio of high-starch miscellaneous grain powder to water has special requirements, it is impossible to realize one-time feeding, and can only batch batches according to a specific ratio of powder and water. The batching tank takes too long for each batch, which will greatly prolong the batching and production time, and increase the cost of energy consumption and manpower.
