Fast automatic deodorization system in vegetable oil refining

Abstract

The invention discloses a fast automatic deodorization system in vegetable oil refining. An oil inlet pipe is arranged at the top end of a deodorization tower; an oil delivery pipe is arranged at the side of the oil inlet pipe; the upper end of the oil inlet pipe is connected with an air return pipe; the air return pipe is connected with a vacuum storage tank; steam nozzles are uniformly arranged on the inner wall of the deodorization tower; a center pipe is arranged at the center of the deodorization tower and connected with an exhaust pipe; the exhaust pipe is connected with a vacuum supply pipe; the upper end of the vacuum supply pipe is connected with the vacuum storage tank and the lower end is connected with a fatty acid capture tank; the lower end of the fatty acid capture tank is connected with a primary storage tank; the primary storage tank is connected with the fatty acid capture tank through a circulating pipe; the circulating pipe is provided with a circulating pump and a heat exchanger; the side wall of the upper end of the primary storage tank is connected with a secondary storage tank through a pipe; the upper end of the vacuum storage tank is connected with a vacuum pump system through a pipe and the lower end is connected with an accumulation tank; the accumulation tank is connected with the secondary storage tank through a pipe; and a valve is arranged on the pipe between the accumulation tank and the secondary storage tank. The uniform vacuum deodorizing treatment of oil can be achieved, the deodorizing speed is high and the effect is good.

Description

technical field [0001] The invention belongs to the field of vegetable oil processing equipment, in particular to a rapid automatic deodorization system in vegetable oil refining and processing. Background technique [0002] During the refining process of vegetable oil, it needs to go through deodorization process to become deodorized refined oil. The deodorization process is usually completed in the deodorization tower, which is used to volatilize or evaporate the odorous fatty acid substances in the vegetable oil. The fraction extracted from the deodorization tower enters the deodorization tower. Fraction capture tower for capture and recovery. The deodorization tower includes the upper shell of the deodorization tower and the lower shell of the deodorization tower connected to each other. The upper part of the upper shell of the deodorization tower is connected with the oil inlet pipe of the packing section, and the outlet of the oil inlet pipe of the packing section is a...

Problems solved by technology

Because the height of the deodorization tower is relatively high, the upper part is relatively close to the vacuum port, and the vacuum effect is better; due to the existence of air resistance, the lower part of the deodorization tower far away from the vacuum port has a poor vacuum effect, and the high-temperature oil is low. The vacuum environment is not only not conducive to the removal of low-component odor substances in the oil, but also easily leads to the polymerization of small molecular components in the oil, which affects the quality of the oil.
