Rapid oil tea fruit shelling method

Abstract

The invention discloses a rapid oil tea fruit shelling method which sequentially includes the steps: (1) aging: placing fresh picked oil tea fruits into an aging machine, and enabling steam with the temperature of 100-120 DEG C to directly contact with the oil tea fruits until the oil tea fruits are softened and cracked; (2) tempering: performing air drying on the oil tea fruits obtained in the step (1) by the aid of hot air with the temperature of 80-120 DEG C, and conveying the dried oil tea fruits for 30-120min; (3) fruit swing: placing the oil tea fruits obtained in the step (2) into a fruit swing machine to swing and separate to obtain oil-tea seed and fruit shell mixture; (4) flotation: placing the oil-tea seed and fruit shell mixture obtained in the step (3) into flotation liquid with the density of 1-1.1g / cm<3>, enabling oil-tea seeds to subside, enabling fruit shells to float upwards, and fishing out and separating the oil-tea seeds and the fruit shell; (5) drying: placing the oil-tea seeds obtained in the step (4) into a drying machine with the temperature of 40-100 DEG C, and drying the oil-tea seeds in the drying machine for 30-90min by the aid of hot air to remove surface moisture of the oil-tea seeds; (6) placing the oil-tea seeds obtained in the step (5) into a bin, performing air drying on the oil-tea seeds in the bin at the lower temperature (40-80 DEG C) to remove inherent moisture of the oil-tea seeds. The method is simple in process step, high in efficiency and low in labor intensity, and seeds and shells are completely separated.

Description

technical field [0001] The invention relates to the processing of oilseed fruit, in particular to a quick shelling treatment method of camellia oleifera fruit. Background technique [0002] Camellia oleifera is a plant of the genus Camellia in the family Theaceae. Camellia oleifera seed is the seed of camellia oleifera tree, and tea oil (also known as camellia seed oil, camellia oil, camellia oleifera oil) can be obtained by 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 area is low, the econom...
