Problems solved by technology

Another example is the Chinese patent application number 02156713.1, which discloses a method for extracting rice bran oil. In this method, completely burnt charcoal is placed on the top of the raw rice bran, and the raw rice bran is subjected to high-temperature combustion of the charcoal, so that it continues from top to bottom. Rice bran oil is produced by smoldering. This method has a low oil yield, wastes more resources, and has certain pollution to the atmosp...

Embodiment

[0022] Referring to Fig. 1 , the rice bran is transported into No. 1 pickling pot 21 by conveyor 1. A stirring paddle is arranged in No. 1 pickling pot 21, and acid solution is filled inside. The rice bran is stirred in the No. 1 pickling pot 21 and settles down. After soaking in the No. 1 pickling pot 21 for about one minute, the rice bran is pumped to the No. 1 vibrating screen 91 through the pipeline at the bottom. The sieve 91 separates the rice bran from the acid solution, and the rice bran enters the No. 2 pickling pot 22 along with the pipeline, while the acid solution returns to the No. 1 pickling pot 21 along with the pipeline.

[0023] The rice bran that enters No. 2 pickling pot 22 still sinks down through stirring, and the rice bran is soaked in No. 2 pickling pot 22 for about 1 minute, and then it is pumped to No. 2 vibrating screen 92 through the pipeline at the bottom. No. vibrating screen 92 separates rice bran and acid solution, and rice bran enters No. 3 pick...

Abstract

The invention relates to a method used for preparing oil by rice bran, belonging to the extraction process of rice bran oil. The existing method used for preparing the rice bran oil directly extracts the rice bran oil extracted from fresh rice bran; the refreshment of fresh rice bran is difficult, thus leading the industry of extracting the rice bran oil from the rice bran to be gradually atrophied and a plurality of resources to be wasted. The invention provides a method used for preparing oil from the rice bran; rice bran and acid solution are taken ready for use; the method is characterized in that the sequence that the wet rice bran and acid solution are separated, the calcium phytate is removed and the rice bran oil is extracted. The method firstly removes the calcium phytate in the rice bran and extracts the rice bran oil subsequently, thus solving the refreshment problem of the fresh rice bran. When the rice bran oil is extracted from the rice bran, the acid value in the rice bran is low, thus reducing the corrosion on the equipment.

Description

technical field [0001] The invention relates to a method for producing oil from rice bran, which belongs to the extraction process of rice bran oil. Background technique [0002] Rice bran oil is a kind of oil extracted from rice bran. Refined rice bran oil is called "nutrition oil" in Japan and the United States, and it is also known as "youth oil". It not only contains richer multivitamins than other edible oils, but also The ratio of saturated acid in oil: monodilute acid: polydilute acid is 1:1:1. This natural ratio is close to the ratio standard proposed by the Food and Agriculture Organization of the United Nations and the World Health Organization. [0003] Rice bran becomes bran meal after extracting rice bran oil and calcium phytate. However, the nutritional value of the bran meal without calcium phytate and oil has been improved for the feed, and the crude protein is close to the standard of 18% crude protein for matching full-price feed. The acid leaching proces...
