Oil tea fruit shelling and screening processing method and equipment

Abstract

The invention discloses an oil tea fruit shelling and screening processing method and equipment. The processing method and equipment are mainly used for fresh oil tea fruit shelling and oil tea seed shell screening. The processing method includes the following steps: (1) conveying fresh oil tea fruits to an oil tea fruit grading machine to grade; (2) respectively sending the fresh oil tea fruits to four sets of expanding shellers to perform shelling according to grades; (3) sending a seed shell mixture to a roller primary selection machine to perform primary screening; (4) performing fine screening through a needle roller fine selection machine; and (5) collecting and packaging the oil tea shells, and collecting and sending the oil tea seeds out. The equipment includes a feeding device, the grading machine, a transmission device, the expanding shellers, the roller primary selection machine and the needle roller fine selection machine. The processing method can overcome the technical disadvantages of complex processes, many processing equipment, low processing efficiency and low seed shell screening efficiency of existing oil tea fruit processing technologies; and the processing method is simple and reasonable in technology process, scientific in equipment structure, time-saving, energy-saving, high in production efficiency, good in cleaning effect and low in production cost, and can process the fresh oil tea fruits in batch.

Description

technical field [0001] The present invention mainly relates to a processing method and equipment for husking and screening of camellia oleifera fruit, and in particular to a method and equipment for bulging camellia oleifera fruit shelling and needle-roller type camellia oleifera seed husk screening. The method and equipment are applicable to large The invention relates to shelling and screening processing of fresh camellia oleifera fruit in batches, belonging to the technical field of camellia oleifera processing. Background technique [0002] Camellia oil and its series of products have good economic value and green health care function, and more and more attract the attention of the world. Because of its unique nutritional value, it is called "the king of oils" and "Oriental olive oil". Due to the low oil content of camellia oleifera husk, camellia oleifera fruit needs to be shelled and screened to obtain camellia oleifera seeds in order to refine pure high-quality camell...

Problems solved by technology

The pure manual method is generally: stack and retting the harvested camellia oleifera for 3 to 5 days to complete the post-ripening process of oil; then spread it out in the sun for 2 to 4 days, and continue to dry for 1 to 2 days after the tea fruit cracks naturally ; Then manual shelling, and then sifting out camellia seeds; the whole processing process is not only inefficient and costly, but also often causes mildew due to the inability to peel the fresh fruits of camellia oleifera in time, which not only causes losses but also affects the quality of camellia oil

The simple mechanical method is generally: according to the difference in size of camellia oleifera fruit, use a multi-layer flat plate or drum vibrating screen to sieve the husks, and then use a blower type sieve to sieve the seed husks according to the difference in the specific gravity of the seeds and husks after drying; The difference in size and specific gravity of the seed husk mixture is small, so the screening effect of the seed husk is poor, and the processing process is complicated, time-consuming and costly
