Description

Double-roller screening device for camellia seeds

Technical Field

The utility model belongs to the technical field of the tea-seed oil production facility, in particular to a twin drum divides sieve device for tea-oil camellia seed.

Background

With the increase of population and the decrease of cultivated land, the vigorous development of woody oil has become a main channel for solving the serious shortage of edible oil in human in the world nowadays. The camellia seed oil is pure natural high-grade edible plant oil extracted from mature camellia seeds of common camellia seeds of camellia plants in the camellia family, and has golden or light yellow color, pure quality, clarity, transparency, fragrant smell and pure taste. More than 90 percent of the global oil-tea camellia seed oil is from China, and is pure natural woody edible vegetable oil advocated and promoted by the Chinese government and health-care vegetable edible oil firstly promoted by the international food and agriculture organization. The edible oil has the effects of reducing cholesterol, improving high-density lipoprotein, reducing low-density lipoprotein, reducing blood fat, preventing cardiovascular and cerebrovascular diseases, improving immunity, resisting radiation, removing free radicals, preventing tumors and the like after being frequently eaten, and is classified as the healthy edible oil which is mainly popularized by the international food and agriculture organization.

The husking and seed separation of the tea fruits is usually needed after husking, and the husking and seed separation of the tea seeds can be realized by adopting a drum screen in the prior art. In the prior art, the mode is usually adopted and is carried out by using a drum screen, the camellia seeds pass through screen holes of the drum screen, and the fruit shells roll out downwards from the drum. The applicant, when dealing with the usual trommel screen, found the following problems:

1. the single trommel treatment is slow and inconvenient to adjust to the amount of processing (tea fruit is mostly purchased from farmers and the amount of processing varies particularly from day to day).

2. When the camellia seeds are used for preparing the camellia oil, although a certain amount of shells are allowed to exist, a small amount of broken shells (small) are generated during husking, and the broken shells can enter the camellia seeds in a large amount in a conventional screening mode to influence the quality of the camellia oil.

3. During screening, if the sizes of the screen holes are consistent, a large number of camellia seeds are screened out at the front end of the drum screen, and the camellia seeds are vacant at the rear end of the drum screen, so that waste is caused, and more husks (oil-free camellia seeds compete with the oil-free camellia seeds) are screened out.
