Problems solved by technology

The water content in the oil increases due to the injection of steam, thereby shortening the shelf life of the oil. In addition, the injection of water vapor into the high-temperature oil will cause a chemical reaction to generate carcinogens. At the same time, adding water vapor to the coil has the disadvantage of slow temperature rise.

Abstract

The invention relates to an odor releasing process of a vegetable oil without residual moisture and the device. A coil pipe is arranged at the lower part in an operating room to let in high temperature hot air; an oil feeding pipe is throughout communicated to the part of a tank from the bottom part, and a valve arranged at the bottom part can ensure the oil to be directly sprayed to the upper part through a gear pump. Because of different processes, the traditional process achieves the purpose of odor releasing through distillation method, the process achieves the purpose of odor releasing through evaporating method, the foreign flavor molecule in the oil is vaporized into gas under heating condition, after the volume is enlarged and the density is decreased, the gas is positioned in thevacuum pipe at the top part at the upper part of the tank, therefore, the gas with foreign flavor is sucked out, and the purpose of odor releasing is achieved; because steam is not required, the equipment investment is reduced, and the shelf life of the produced oil is prolonged.

Description

technical field [0001] The invention relates to a vegetable oil processing technology and equipment, in particular to a vegetable oil deodorization technology and device without moisture residue. Background technique [0002] At present, the traditional deodorization method of vegetable oil is to pass high-temperature steam into the vacuum deodorization tank, and the steam is mixed with the oil to rush up together. By strengthening the effect of distillation, the peculiar smell in the oil is brought out with the steam. Due to the injection of steam, the water in the oil increases, thereby shortening the shelf life of the oil. In addition, the injection of steam into the high-temperature oil will cause a chemical reaction to generate carcinogens. At the same time, the addition of steam into the coil has the disadvantage of slow heating. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a vegetable oil deodorization process and device that ...
