Description

  The present invention relates to an apparatus for producing dried persimmons.

  Traditionally, dried persimmons were manufactured by peeling astringents such as Saijo persimmons, Tone persimmons, Yokono persimmons, Atago, etc., and then drying them in the sun. The astringency contained in astringency is due to the tannin in the pulp, and when the tannin is a water-soluble tannin, there is astringency, and the astringency is lost by changing to insoluble tannin. It has been known that the astringency can be eliminated by drying in the sun. However, the days required for sun-drying are very long, from 20 days to one month, and the dry days fluctuate depending on the weather, or the quality deteriorates due to blackening or the like. In addition, in this sun drying, mold and rot may occur depending on the weather, and the yield may be lowered, and it is difficult to systematically deliver the finished product.

  Then, in order to shorten the drying days, the method of drying in the drying chamber provided with the heater and the dehumidifier after peeling the skin of astringency has been proposed (for example, refer patent document 1). Patent Document 1 discloses a drying process in which a bag is stored in a drying chamber having a dehumidifier and a dryer, and is dried and dehumidified by being adjusted to a predetermined temperature, and a drying process that is adjusted to an appropriate temperature for drying. It describes about the manufacturing method of the dried persimmon which performs alternately. In this case, the wind direction and the air volume of the hot or cold air jet port injected from the dryer are not particularly limited, and drying unevenness occurs, resulting in a decrease in yield.
