Camellia oil cold pressing and molecular distillation device and oil preparation method

Abstract

The invention relates to the camellia-seed oil pressing and refining technology, in particular to a camellia oil cold pressing and molecular distillation device and an oil preparation method. The camellia oil cold pressing and molecular distillation device comprises a camellia seed screening system, a low-temperature drying system, a husk-kernel separating system, a fine screening system, a smashing system, a low-temperature pressing system, a fine filtering system and a molecular distillation system which are connected in sequence, and the fine screening system comprises a screening machine and a winnowing machine. Camellia oil prepared with the device and method is of the first pressing grade according to the national standard, has the unique fragrance and taste of camellia seeds, is free of odor, and has a clear and transparent color. According to the camellia oil cold pressing and molecular distillation device and method, husks obtained through separation of a husking machine and wrongly classified kernels and husks in kernels are picked out through the fine screening system, picking and utilizing of kernel residues in the husks can be achieved, high-quality materials are provided for molecular distillation, and then camellia seed materials are saved and the oil yield is increased.

Description

technical field [0001] The invention relates to a pressing and refining process of camellia seed oil, in particular to a camellia oil cold pressing and molecular distillation equipment and an oil production method. Background technique [0002] Camellia oil, also known as Camellia oleifera seed oil, is obtained from the seeds of the Camellia oleifera plant, and is one of the oldest traditional woody edible vegetable oils in my country. Camellia oil also contains various active substances such as tea polysaccharides, camellia saponins, flavonoids, tea polyphenols, vitamins and phytosterols. Regular consumption can reduce cholesterol, increase high-density lipoprotein, reduce low-density lipoprotein, lower blood fat, and prevent heart disease. For cerebrovascular diseases, improving immunity, anti-radiation, scavenging free radicals, preventing tumors and other effects, the International Food and Agriculture Organization has listed it as a healthy edible oil that is mainly pro...

Problems solved by technology

Existing low-temperature cold-pressed camellia oil has the following problems: one is that the existing peeling machine sieves the nuts and shells according to the particle size, so the nuts with large particles are easily used as shells, and the shells with small particles are easily used as shells. As nuts are misclassified, so the nuts and shells after shelling need to be sorted manually, with low degree of mechanization and slow work efficiency; second, the sieved nuts cannot be completely separated from the shells, There is a certain amount of nut shell in it, and directly entering the cold-pressed oil will directly affect the refining process and oil quality of the oil; the third is that it is discarded, and the fruit shell also contains a certain amount of nuts, and directly discarding the fruit shell will affect the quality of the oil. Waste raw materials and reduce the oil yield of raw materials
