Embodiment 1

[0039] As the first embodiment of the drying device used in the drying method for changing the appearance and flavor of raisins according to the present invention, the structure is as follows figure 1 As shown, the bracket 10 and the dome top 20 arranged on the upper part of the bracket 10 are included. The bracket 10 is a frame structure formed by overlapping horizontal rods 12, longitudinal rods 11 and vertical rods 13, and the materials used for overlapping the brackets are wooden rods, steel pipes, etc. In this embodiment, the width of the drying device is determined according to the local wind direction, wind speed, etc., and is usually set to 1.5-2m; the length of the drying device depends on the size of the site, the number of dried grapes required, and the scale of drying. The demand is determined, usually 1-20m; the height of the drying device is generally 1.5-2.5m, which is convenient for ordinary people to operate.

[0040] In this embodiment, a plurality of layers of ...

Embodiment 2

[0046] As the second embodiment of the drying device used in the drying method for changing the appearance and flavor of raisins according to the present invention, the structure is as follows figure 2 As shown, the difference between this embodiment and the first embodiment lies in the different ventilation devices used. In this embodiment, the ventilation device includes an air outlet provided on the greenhouse film or plastic light-transmitting film. The air outlet is provided with an exhaust fan 60. The exhaust fan 60 is powered by ordinary civilian electricity. Of course, in the field power supply facilities In the case of incompleteness, it can also be powered by solar panels or small wind turbines. In the drying device of this embodiment, the air is exhausted when the humidity is high in the early stage of drying, and the air can also be manually exhausted at noon every day to reduce the temperature in the device and accelerate the drying speed.

[0047] The drying device...

Embodiment 3

[0050] As the third embodiment of the drying device used in the drying method for changing the appearance and flavor of raisins according to the present invention, the structure is as follows figure 2 , image 3 As shown, the main structure is the same as the drying device of the second embodiment. The difference between this embodiment and the second embodiment is that it also includes a controller 70, a temperature sensor 71, and a humidity sensor 72. , The humidity sensor 72 and the exhaust fan 60 are electrically connected. When the temperature and humidity exceed the limit value, the exhaust fan automatically runs, thereby reducing the temperature in the device and speeding up the drying speed. Preferably, in this embodiment, the limit value of temperature is 45° C., and the limit value of humidity is 60%.

[0051] The drying device of this embodiment has a relatively simple structure and relatively convenient operation. The site for its construction is not restricted, and ...

Abstract

The invention discloses a raisin production method for changing the appearance characteristics and the flavor of raisins. The method comprises the steps of screening, cleaning, grape drying promoter treatment, and hanging and airing of grapes in a raisin production device; and the raisin production device comprises a support and an arc-shaped roof arranged at the upper portion of the support, the support is formed through overlapping transverse rods, longitudinal rods and vertical rods, a plurality of brackets for hanging and airing grapes are arranged in the support, and the support and the arc-shaped roof are covered with an agricultural film for greenhouse or a sunshade screen. The covering material on the raisin production device is used to control the illumination intensity and change the spectral component in order to produce raisins with different colors and different flavors. Compared with traditional direct airing technologies, the method disclosed in the invention has the advantages of short raisin production time, and realization of cleanness, uniform color, elongated and elliptical shape, beautiful appearance and obvious improvement of the market values of produced raisins; and compared with color change raisin production devices in the prior art, the raisin production device adopted in the invention has the advantages of simple structure, low cost, small requirements of places, and suitableness for being massively promoted in common orchard workers.

Description

technical field [0001] The invention relates to the technical field of fruit drying, in particular to a drying method for changing the appearance and flavor of raisins. Background technique [0002] Grapes are a characteristic fruit in Xinjiang, with the characteristics of large output, many varieties, and good quality. Raisins are also a characteristic dried fruit in Xinjiang. Fruit farmers usually make raisins directly from the sun or in an adobe drying room with ventilation on all sides. The raisins produced by this method have poor uniformity in color and taste, and the quality is average. [0003] The Chinese utility model patent with the notification number CN204180899U discloses a dried fruit steam heating cold and warm air cooling and discoloration device. The patent discloses a dried fruit discoloration method and a dried fruit discoloration device. The drying devices disclosed in the above-mentioned patent documents can control and change the discoloration and ta...
