Camellia oleifera fruit hulling treatment method through flotation separation

Abstract

The invention relates to a camellia oleifera fruit hulling treatment method through flotation separation. The camellia oleifera fruit hulling treatment method comprises the following steps of (1) throwing fruits: throwing fresh picked camellia oleifera fruits into a fruit throwing machine, thoroughly polishing camellia oleifera fruit shells, and performing extrusion and dispersion so as to obtain a camellia oleifera seed and camellia oleifera fruit shell mixture; (2) performing conditioning: performing air-drying transportation on the camellia oleifera seed and camellia oleifera fruit shell mixture obtained in the step (1) at thermal wind of 40-100 DEG C for a transportation period being within 30min, or performing microwave transportation at low frequency being 300MHz-915MHz for a transportation period being within 2min, so that the moisture of fruit shells is maintained to be 30-60%; (3) performing flotation: putting the camellia oleifera seed and camellia oleifera fruit shell mixture obtained in the step (2) into flotation fluid, wherein the density of the flotation fluid is 1-1.1g / cm<3>, enabling camellia oleifera seeds to sink, enabling fruit shells to float upwards, and separately fishing out the camellia oleifera seeds and the fruit shells so as to realize separation; and (4) performing baking: putting the camellia oleifera seeds obtained in the step (3) into a baking machine of 40-100 DEG C, performing thermal wind drying for the time of 30-90min, and removing surface moisture. The method is simple in technological processes, low in requirements for technological conditions, simple in equipment, and small in flour space, and continuous unrestricted mass production can be realized.

Description

technical field [0001] The invention relates to the processing of oil plant fruit, in particular to a method for shelling camellia oleifera fruit separated by flotation. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae, and camellia oleifera seed is the seed of the camellia oleifera tree. Camellia oil (also known as camellia seed oil, camellia oil, camellia oleifera oil) can be obtained through leaching or pressing. Camellia oil is a healthy and delicious edible oil. It not only has good color, fragrance and taste, but also has the effect of preventing cardiovascular diseases such as hypertension, coronary heart disease and atherosclerosis. It has important development and utilization value, but the current industry Existence: 1. People don’t know enough about the value of camellia oleifera, and don’t pay enough attention to it; 2. The proportion of fine varieties is low, the management is extensive, the output per unit ...
