Pretreatment technology of oil-tea camellia seed

Abstract

The invention provides a pretreatment technology of an oil-tea camellia seed. The pretreatment technology of an oil-tea camellia seed comprises the following steps of 1, packaging collected oil-tea camellia fruits by air permeable bags, 2, after packaging and stacking, drying the packaged oil-tea camellia fruits under the conditions of a drying temperature of 25 to 45 DEG C, air humidity of 40 to60% and drying time of 2 to 3 days until shells of the oil-tea camellia fruits crack, wherein each one pile comprises 1 to 5 bags of the oil-tea camellia fruits; the weight of each bag of the oil-teacamellia fruits is in a range of 30 to 35kg; and gaps exist among the piles, 3, carrying out shell removal of the dried oil-tea camellia fruits by a physical method to obtain oil-tea camellia seeds, 4, packaging the oil-tea camellia seeds by air permeable bags, and 5, after packaging and stacking, drying the packaged oil-tea camellia seeds under the conditions of a drying temperature of 25 to 45 DEG C, air humidity of 30 to 50% and drying time of 4 to 7 days, wherein each pile comprises 1 to 5 bags of the oil-tea camellia seeds; the weight of each bag of the oil-tea camellia seeds is in a range of 25 to 30kg; and gaps exist among the piles. The pretreatment technology of an oil-tea camellia seed saves manpower and material resources, improves efficiency, reduces energy consumption and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a pretreatment process of camellia oleifera seeds, specifically drying and shelling fresh camellia oleifera fruits, and drying the camellia oleifera seeds obtained after shelling, and belongs to the technical field of agricultural product processing. Background technique [0002] Camellia oil has been listed as a healthy edible vegetable oil by the United Nations Food and Agriculture Organization. The development of camellia oleifera industry has received increasing attention from governments at all levels and the people. Nowadays, the planting area of ​​camellia oleifera is expanding rapidly, and camellia oleifera seeds are being processed and utilized on a large scale. After the fresh fruits of camellia oleifera are picked, the separation of tea seeds and husks and the drying of tea seeds are the first steps in the processing and utilization of camellia oleifera seeds, which have an important impact on the subsequent storage a...

Problems solved by technology

The current pretreatment process is mainly carried out by farmers after picking, stacking and retting, manually peeling and selecting seeds, and drying naturally. Enterprises use dryers to dry tea seeds at high temperature and quickly. This method consumes a lot of energy, which greatly increases the processing cost, and high temperature drying will easily lead to a decrease in the oil yield of tea seeds, and an increase in the peroxide value and acid value of oil.

For example, the patent document with the application number 201010196383.6 discloses a drying method of camellia oleifera seeds. In this method, the tea fruit is stacked and retting for 8 to 12 days, and the tea seeds are dried quickly at high temperature, which not only leads to the oil content and yield of the tea seeds Lower oil rate and higher energy consumption
