Device and technology for damage-free hulling and color sorting of tea-oil tree fruit

Abstract

Disclosed are a device and technology for damage-free hulling and color sorting of tea-oil tree fruit. The device comprises a hulling assembly, a vibrating screen (7), a guide groove (8) and a color sorting separating assembly. The hulling assembly, the vibrating screen (7) and the color sorting separating assembly are connected in sequence. The technology includes the four steps including grading, grinding hulling, separating and color sorting. The device and technology can be used for processing a wide range of tea-oil tree fruit and processing green fruit which is just picked as well as tea-oil tree fruit which has been tedded for one or two days; the tea-oil tree fruit in a wide size range can be sorted by adjusting gaps of grating bars of a cylindrical grating grading mechanism, therefore, the size of the tea-oil tree fruit entering a grinding mechanism can be fixed within a certain range, and grinding efficiency and the grinding effect are improved; because a gap between a grinding wheel and a grinding bottom plate can be adjusted through a gap adjusting mechanism, hulling rate is further improved, and fruit grain damage rate is lowered; the picture processing and control technology is applied to tea-oil tree fruit hulling and fruit nut sorting by using the difference between the color of hulls and the color of fruit nuts, and sorting efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of camellia oleifera fruit processing, in particular to a device and process for the non-destructive shelling and color cleaning of camellia oleifera fruit. Background technique [0002] Camellia oleifera is an important woody oil tree species unique to my country. It is mainly distributed in 18 southern provinces of my country, including Hunan, Jiangxi, Guangxi, and Guizhou, with a cultivation area of ​​about 3.67 million hectares and an annual output of about 200,000 tons of camellia oil. Camellia oil is a high-quality edible oil with a high content of unsaturated fatty acids. Its nutritional and health value is no less than that of olive oil. It is called "Oriental Olive Oil". At present, the development of the Camellia oleifera industry has received great attention, and the country has positioned the industry as a strategic plan to ensure the safety of food and oil for the people’s livelihood. According to t...

Problems solved by technology

At present, most of the camellia oleifera fruits in the actual production are stacked and retting, and the method of spreading the tea leaves promotes the cracking of the camellia oleifera fruits, and then manually cleans them manually, which is extremely labor-intensive.

[0004] The publication number is CN 102845809A, and the invention patent application titled "Camellia oleifera shelling machine" adopts the method of winnowing to clean the husks and fruit pieces, b
