Abstract

The present invention discloses a manufacturing and processing method of dried wild apricots by using a solar energy air flow drying. The method comprises the following steps: raw material pretreating, soaking, air-drying, solar energy drying, finished product testing and finished product packaging. The drying period is short and the rate of finished products is high. A solar energy hot air flow is used, and the method enables the heat energy of the hot air to be transferred from the inner surface and external surface of the dried apricots at the same time to the inside, and speeds up the heat transfer rate. At the same time, the water inside the dried apricots moves to the surface after the apricots are heated, the water moving to the surface layer is rapidly vaporized, the water is exhausted out from the inside of a solar energy drying box by an exhaust fan, and the transfer of the water is sped up. The method can conduct a hot air temperature adjustment according to the different water inside the dried apricots, more raw materials can be contained in the unit area, a surface color protective liquid is used, and the method can keep the original bright color and luster of the dried apricots while speeding up the drying of the dried apricots.
