Fragrance recycling method based on multistage condensers

Abstract

The invention discloses a fragrance recycling method based on multistage condensers. The method comprises the steps that the multistage condensers are provided and arranged above a reaction tank, the multistage condensers are distributed in the horizontal direction, the bottom end of the first-stage condenser is connected to the reaction tank through an air inlet pipeline from front to back, and the top end of the front-stage condenser is simultaneously connected to the bottom end and the top end of the rear-stage condenser through a first pipeline; a liquid drainage pipe is arranged at the bottom end of each condenser, a first valve is arranged on each first pipeline, and each liquid drainage pipe is connected to the reaction tank. From front to back, the temperature of cooling circulating water continuously introduced into the multistage condensers is gradually reduced, and the temperatures of the cooling circulating water in every two adjacent condensers differ by 3 DEG C to 6 DEG C; after a Maillard reaction is started, the first valves are switched on step by step from front to back, and one first valve is switched on every other a first time period. The recycling effect of fragrance ingredients is improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to an aroma recovery method based on a multistage condenser. Background technique [0002] During the Maillard reaction process with osteonin as the base material, many volatile aromas will be produced, which play a key role in the taste and quality of the entire reaction product. In the conventional production process, Maillard reaction is divided into room temperature and high temperature reaction, and high temperature Maillard reaction is mostly. The pressure of the reaction tank corresponding to the high temperature reaction is high. After the reaction is completed, the pressure release will cause a great loss of aroma. To avoid the loss, the method of lowering the temperature of the tank is generally adopted. However, although the method for cooling the tank body can reduce the loss of aroma, the cooling time will be long and the energy consumption will be large. At present, two-stage condensers are usually used to recover ...

AI Technical Summary

Problems solved by technology

However, although the method of cooling the tank can reduce the loss of aroma, it will take a long time to cool down and consume a lot of energy.

At present, two-stage condensers are usually used to recover aroma components, but the recovery effect of aroma components is not ideal, and the energy consumption is still relatively large
