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 for camellia oleifera fruit, which comprises the following steps: (1) picking; (2) stacking treatment: stacking the picked camellia oleifera fruit indoors, adding ethylene into the stacking room to perform ripening treatment; and then adopting air circulation (3) primary drying: place the processed Camellia oleifera fruit in the sun to dry, and peel off; (4) Secondary drying: Put the camellia oleifera seeds into the pretreatment solution for soaking, Dry the water and add it to a hot air dryer to dry; place the dried camellia seeds in a normal temperature and light-proof environment for storage. The method provided by the invention can greatly shorten the storage time of fresh camellia oleifera after picking, and reduce the mildew rate of the camellia oleifera; during the drying process, the camellia oleifera seeds can be evenly heated, reducing the drying time and drying heat energy loss. The treated camellia seed of the invention has long storage period and high storage 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...
