Flotation agent and separation method of camellia seeds

Abstract

The invention provides a flotation agent and a separation method of camellia seeds. According to the flotation agent, low-density liquid of which the density is 0.90 to 0.99 g / cm<3> is used as a mainbody of the flotation agent, micro-nano bubbles are dispersed in the main body of the flotation agent, the diameter of the micro-nano bubbles is 20 to 50 mum, and the solution volume ratio of the bubbles to the main body of the flotation agent is 1:10 to 1:20. When the flotation agent is used for efficiently floating and separating the camellia seeds and camellia shells, the adaptability to camellia seed raw materials is wide, the separating effect is good, the flotation speed is high, and large-scale continuous production is easy.

Description

technical field [0001] The invention relates to the technical field of production and processing of camellia oleifera, a woody oil plant, in particular to a method for efficiently flotation-separating camellia oleifera seeds and camellia oleifera husks by using a flotation agent combined with micro-nano bubbles and a low-density solution. Background technique [0002] Camellia oleifera is an important woody oil crop of the genus Camellia in the family Theaceae. The camellia oleifera seeds that are broken and stripped from its fruit can be used to extract camellia oleifera oil (also known as camellia oil, tea seed oil). Camellia oleifera oil is rich in Oleic acid, VE, etc., the nutritional value is comparable to olive oil, and long-term consumption can help prevent cardiovascular and cerebrovascular diseases; the remaining camellia husk (also known as Camellia oleifera) after peeling off the camellia seed does not contain oil, but contains lignin, polyphenols and Saponin also...

AI Technical Summary

Problems solved by technology

However, the existing flotation technology, especially the selection of flotation agents, has high requirements for the density of camellia oleifera seeds in actual processing, and the density of camellia oleifera seeds must be greater than 1.0g / cm 3 Even greater than 1.1g / cm 3 In order to effectively realize the separation of camellia seed and husk through density difference

However, due to the interference of Camellia oleifera species, maturity, picking timing, preparation process and other factors, the density range of Camellia oleifera seeds is large, especially Camellia oleifera seeds are prone to produce cavities during drying and drying of Camellia oleifera fruit, resulting in a density of less than 1.0g / cm 3 , with a density of 1.0 ~ 1.1g / cm 3 The flotation agent will have a large number of camellia seeds also float quickly, and they will be mixed with the fruit shell to cause serious losses and decrease the flotation efficiency.

Therefore, the existing flotation separation technology of camellia oleifera seeds and camellia oleifera shells has strict requirements on the density of camellia oleifera seeds. In actual production, the requirements for the pre-processing of raw materials are strict, the production process is difficult to control, and the applicable range of raw materials is relatively narrow.
