Abstract

The invention relates to a method and a system for recovering aroma substances in the production process of instant coffee. According to the method, the aroma substances lost in the coffee grinding process are recovered by virtue of the water spraying condensation of a freezing process in an adsorption tower and aroma substances in an extraction process and a concentration step are recovered by virtue of flashing, displacement, concentration and adsorption, so that the aroma substances easy to lose and damage in the production process of the instant coffee are recovered in all directions; according to the method for recovering the aroma substances in the production process of the instant coffee, in sufficient combination with the production process of the instant coffee and based on the principle of high-temperature and high-pressure extraction of the coffee, the easily-volatile aroma substances in a high-temperature and high-pressure extract are quickly separated from material liquid by use of the flashing technology, and then the separated-out easily-volatile aroma substances are purified and concentrated, and finally backfilled to the coffee concentrate; the original aroma quality of instant coffee is retained to the utmost extent. Besides, water is taken as a condensate in the method, and is free of pollution, reusable and low in energy consumption; the method has obvious advantages in technology and economy, and can be widely applied to recovering the aroma substances in the industrial production, and the production cost can be saved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method and a system for recovering aroma substances in the production process of instant coffee, which can recover the aroma substances in the whole process of instant coffee production. Background technique [0002] Coffee, tea and cocoa are known as the world's three major beverage plants. About one-third of the world's population drink it. Coffee is second only to oil in global trade. Coffee is rich in protein, crude fiber, crude fat, caffeine, etc. Because of its unique mellow taste and refreshing and exciting effects, it has gradually become an indispensable daily drink for modern people. With the accelerating pace of life in modern society, more and more people who like to drink coffee are accepting instant coffee compared to the more complicated traditional coffee brewing methods. Instant coffee is a dry coffee extract obtained by evaporating the water in the coffee extra...
