The invention relates to a whey food processed from cereals harvested at a
grain filling later stage at high-quality air, kept fresh at high-quality air and eaten at high-quality air. The outmoded custom that humans eat and store withered food grains is changed, the whey food has great significance but is very simple, as long as crops are harvested during the period from the time that the crops grow to a
grain filling stage to the time before plants begin to decline, the harvested rice ears, harvested wheat ears, corn sticks and the like are directly conveyed into a food
production line, a fresh tender whole-juice grain-fragrance whey food is processed, then sealed packaging is performed, the whole course is performed under the ultracleaned, disinfected and sterilized condition, and then the products are conveyed into a ground-temperature water molecule atomized modified-
atmosphere fresh-keeping storage warehouse only using natural resources; even if the products are stored for 2-3 years, the products are still high-
nutrition fresh tender delicious foods when being sold to the market; and if people can have a
meal in a house with a high-quality air central air conditioner only using natural resources, the people do not need to worry about getting ill after eating. On rainy days during a brief
harvest season, the quality and the
processing of the products are not influenced when the cereals are harvested with water. The trouble of living at the mercy of natural condition is avoided,
threshing,
drying and a
processing course of rice and flour plants, which are time-consuming and money-consuming, are omitted, and the time that the crops occupy land is saved by several days to tens of days. The problems that grain reserves are deteriorated to generate loss and high subsidy is needed are completely solved.
