Abstract

The invention belongs to the technical field of vegetable oil extraction, and discloses a camellia oil hydraulic squeezing method based on a response surface method and a multi-objective genetic algorithm, which comprises the following steps: (1) sequentially changing the squeezing temperature, the squeezing time, the squeezing pressure and the water content of camellia seeds to carry out a singlefactor test on a camellia seed sample; (2) respectively establishing multivariate quadratic regression equations by taking the squeezing temperature, the squeezing pressure, the squeezing time and the water content of the camellia seeds as independent variables and taking the oil yield and the energy consumption as response values; analyzing according to the established multivariate quadratic regression equation to obtain a response surface map, and then confirming the optimal pressing temperature, the optimal pressing time, the optimal pressing pressure and the optimal camellia seed water content; and (3) carrying out hydraulic squeezing on the camellia seeds with the water content of the optimal camellia seeds at the optimal temperature and pressure, wherein the squeezing time is the optimal squeezing time. According to the method, the cost is reduced, the oil yield is increased, the flexibility is good, and the applicability is high.

Description

technical field [0001] The invention belongs to the related technical field of vegetable oil extraction, and more specifically, relates to a method for hydraulic pressing of camellia oil based on response surface method and multi-objective genetic algorithm. Background technique [0002] Camellia oil is a unique woody oil in my country. Its fatty acid composition is similar to olive oil, the best vegetable oil recognized in the world. It is known as "Oriental olive oil". Camellia oil also contains a variety of nutritional functional ingredients, which have the effects of preventing cardiovascular sclerosis, lowering blood pressure, and lowering blood fat. [0003] In industrial production, the preparation methods of oil mainly include pressing method and leaching method. The oil extraction rate of the leaching method is relatively high, but its application and popularization are limited due to defects such as solvent pollution affecting the oil quality and increasing the co...
