Embodiment 1

[0018] After harvesting fresh Xiangling walnuts, peel them according to the following steps:

[0019] (1) Place the harvested fresh Xiangling walnuts on a layered grid, and lay a layer of walnut fruit on each layer. The grid is made of fine iron wire, and the grid has 3 to 5 layers. The number of layers should not be too many to avoid incomplete spraying when spraying ethephon solution;

[0020] (2) After the walnut fruit is laid, spray the walnut fruit with a concentration of 0.3% to 0.5% ethephon solution. The spraying method is from bottom to top. The ethephon solution is sprayed at 0.5L per second, and the spraying time is controlled for half a minute. ;

[0021] (3) After spraying, turn on the hot air blower for hot air drying. The blowing temperature of the hot air blower is 200-250°C, and the hot air drying time is 20-30 minutes. Hot air blower;

[0022] (4) After the hot air drying is completed, spray with 0.1% to 0.3% ethephon solution. The method of spraying is fr...

Embodiment 2

[0030] Harvest fresh fragrant variety walnuts, peel according to the peeling method of example 1, and its sample observation test result is shown in Table 2.

[0031]

Embodiment 3

[0033] Harvest fresh longan variety walnuts, peel according to the peeling method of example 1, and its sample observation test results are shown in Table 3.

[0034]

[0035] Result analysis and discussion: From the sample observation results of examples 1 to 3, the walnut peeling efficiency is related to the harvest time and walnut variety. The later the harvest time, the better the peeling effect and the higher the peeling degree. , the present invention suggests that walnuts should be harvested in good time, generally in mid-September.

Abstract

The invention discloses a method for skinning walnuts by hot-air drying and blowing and ethephon spraying. The method is characterized by including paving harvested green-skin walnuts on a layered block rack, spraying with ethephon by times prior to hot-air drying and blowing, and then stacking the green-skin walnuts in a cool place or indoors at the temperature of 30 DEG C and relative humidity of 80%-95% for 3-4 days, wherein skinning rate reaches above 98%. The method has the advantages of high skinning rate and high skinning degree.
