Embodiment 1

[0027] A low-temperature drying method for Camellia oleifera, comprising the following steps:

[0028] (1) Picking: 3-4 days before picking, spray the nutrient solution to the camellia oleifera fruit, and then pick the camellia oleifera fruit;

[0029] (6)(2) Stacking treatment: stack the camellia oleifera fruits picked indoors, add ethylene to the stacking room for ripening treatment, control the ethylene concentration and flow rate, and process for 24 hours; then use an air circulation machine to carry out air circulation treatment indoors , cycle treatment once every 20 minutes, air replacement and cycle treatment once every 6 hours, control the volume fraction of carbon dioxide in the room <15%, and treat for 24 hours; remove moldy and rotten fruits;

[0030] (3) Primary drying: place the processed Camellia oleifera fruit in the sun to dry in the sun until the shell cracks, put it into a peeling machine and take out the shell to obtain Camellia oleifera seeds;

[0031] (4...

Embodiment 2

[0038] A low-temperature drying method for Camellia oleifera, comprising the following steps:

[0039] (1) Picking: 3-4 days before picking, spray the nutrient solution to the camellia oleifera fruit, and then pick the camellia oleifera fruit;

[0040] (2) Stacking treatment: stack the camellia oleifera fruits picked by the phenomenon indoors, add ethylene to the stacking room for ripening treatment, control the ethylene concentration and flow rate, and process for 30h; Circulate once every 22 minutes, and replace the air once every 6 hours, control the volume fraction of carbon dioxide in the room < 15%, and treat for 30 hours;

[0041] (3) Primary drying: place the processed Camellia oleifera fruit in the sun to dry in the sun until the shell cracks, put it into a peeling machine and take out the shell to obtain Camellia oleifera seeds;

[0042] (4) Secondary drying: soak the camellia oleifera seeds in the pretreatment solution for 1-2 minutes, then dry the water and add it...

Embodiment 3

[0049] A low-temperature drying method for Camellia oleifera, comprising the following steps:

[0050] (1) Picking: 3-4 days before picking, spray the nutrient solution to the camellia oleifera fruit, and then pick the camellia oleifera fruit;

[0051] (2) Stacking treatment: stack the camellia oleifera fruit picked indoors, add ethylene to the stacking room for ripening treatment, control the concentration of ethylene and the flow rate, and process for 36 hours; Circulate treatment once every 25 minutes, replace the air every 6 hours, control the volume fraction of carbon dioxide in the room <15%, and treat for 36 hours; remove moldy and rotten fruits;

Abstract

The invention relates to a low-temperature drying method of camellia oleifera fruits. The low-temperature drying method comprises the following steps of (1) performing picking; (2) performing stackingtreatment: stacking the picked camellia oleifera fruits in a room, adding ethylene to the stacking room, performing ripening treatment, and then performing air circulation treatment in the room withan air circulation machine; (3) performing primary drying: placing the stacked camellia oleifera fruits under sunshine, performing airing, and performing peeling; and (4) performing secondary drying:placing camellia oleifera seeds in pretreatment fluid, performing soaking treatment, performing airing to remove moisture, adding the aired camellia oleifera seeds to a hot air drying machine, performing drying, and placing the dried camellia oleifera seeds in a normal-temperature light-resistant environment for storage. According to the method provided by the invention, the stacking time of the picked fresh camellia oleifera fruits can be greatly shortened, and the mildew rate of the camellia oleifera fruits can be reduced; and in the drying process, the camellia oleifera seeds can achieve the effect of being uniformly heated, the drying time is shortened, and the drying heat energy loss is reduced. The camellia oleifera seeds treated by the low-temperature drying method disclosed by theinvention are long in storage life and high in preservation quality.

Description

technical field [0001] The invention belongs to the technical field of camellia oleifera storage, and in particular relates to a low-temperature drying method for low-temperature drying of camellia oleifera fruit. Background technique [0002] Known as "Oriental olive oil", Camellia oleifera is one of the most famous woody oil plants in the world. The oil content of camellia oleifera seed is about 25-35%. The pressed camellia oil mainly contains oleic acid, linoleic acid and other components. Its fatty acid content is very similar to that of olive oil, and even some nutritional indicators are slightly higher than olive oil. Because camellia oil has extremely high nutritional value and is a high-grade healthy edible oil comparable to olive oil, it has been promoted by the International Food and Agriculture Organization as one of the key points. [0003] At present, the production of camellia oil is still in its infancy, and the demand for high-quality edible oil is increasin...
