Problems solved by technology

[0005] The traditional drying treatment technology of fresh camellia oleifera is: stacking to accelerate ripening→drying and shelling→drying; the process of stacking and accelerating ripening is to stack fresh camellia oleifera fruit directly indoors to ripen, and the heat generated by the respiration of camellia oleifera fruit during the stacking process leads to rotten fruit Phenomenon: long drying time for drying and shelling, high labor cost, and easy to be affected by weather

Abstract

The invention relates to a novel composite drying method of camellia oleifera fruits. The method comprises the following steps: (1) stacking the picked fresh camellia oleifera fruits in a stacking chamber, laying a layer of heat dissipation composite material on the ground before stacking the camellia oleifera fruits, and then stacking the camellia oleifera fruits; (2) spraying a cracking promoteron the surface of the camellia oleifera fruits during stacking; (3) adding compound sand into a frying machine, performing heating, adding the camellia oleifera fruits, performing stir-frying, performing cooling, and performing peeling to obtain camellia seeds; (4) placing the camellia seeds into osmotic treatment liquid for treatment, performing freeze-drying, and placing the frozen camellia seeds into a cold-hot air dryer for drying; and (5) treating the dried camellia seeds by adopting far infrared radiation, and performing storing. The low-temperature drying method for the camellia oleifera fruits provided by the invention can effectively reduce the rotten fruit rate in the process of stacking the camellia oleifera fruits; and the camellia seeds can be heated uniformly in the drying process, and the camellia seeds are prevented from being heated unevenly to cause oil extraction of the camellia seeds. The camellia seeds dried by the method have long storage period and high storagequality.

Description

Technical field [0001] The invention belongs to the technical field of oil tea storage pretreatment, and in particular relates to a novel composite drying method for oil tea fruit. Background technique [0002] Camellia oleifera is known as the "Oriental Olive Oil" and is one of the most famous woody oil plants in the world. The oil content of camellia seeds is about 25-35%. The pressed tea oil mainly contains oleic acid and linoleic acid. Its fatty acid content is very similar to olive oil, and some nutritional indicators are even slightly higher than olive oil. Because camellia oil has extremely high nutritional value, it is a high-end healthy edible oil comparable to olive oil, and 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 increasing year by year. This also makes the development of the camellia oil...
