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
The present invention relates to food processing field, be specifically related to a kind of method and system reclaiming aroma substance in instant coffee production process, omnidistancely can reclaim aroma substance in instant coffee production process.
Background technology
Coffee and tealeaves, cocoa be called the large beverage plant in the world three, the whole world about has the population of 1/3rd to drink, and coffee is only second to oil in global trade volume.Coffee contains rich in protein, crude fibre, crude fat, caffeine etc., because of it, there is unique sweet-smelling taste and refresh oneself, excited effect, become the indispensable daily drink of modern gradually.Along with the continuous quickening of modern society's rhythm of life, compare comparatively complicated traditional coffee and brew mode, like the people drunk coffee to get more and more and accepting instant coffee.Instant coffee is the coffee-extract of drying by the moisture evaporation in coffee extract being obtained, with its can be very fast the space of dissolving in the hot water, taking in storage and transport process and volume is less, the feature of more for shelf-stable, obtain popular widely.
Instant coffee production process comprises: select materials, cure, grind, extract, centrifugal, concentrated, allotment, dry, and the Volatile infochemicals in production process contained by coffee is easy to volatilization or destroyed rotten.For Coffee Grinding operation, the flavor substance in coffee is unstable, volatile in process of lapping.Roasting in process, coffee bean inside defines the high pressure of 1.6MPa, and the earth pressure release when coffee bean is pulverized, causes volatile flavor substance to scatter and disappear in a large number, and it is serious that research shows have 22 kinds of flavor substances to scatter and disappear.For extraction and enrichment process, existing heating, vacuum evaporates the large quantity of moisture in coffee feed liquid under being concentrated in uniform temperature, certain pressure (negative pressure), volatile aroma substance is also distilled out of, in final concentrate, the loss of effumability aroma substance and destruction are comparatively serious, larger on the impact of instant coffee flavouring essence quality.
Each operation of instant coffee production process more or less also exists loss and the destruction of fragrance, by the improvement of technique, equipment and optimization, is all not enough to allow the fragrance of instant coffee infuse coffee close to existing mill.
Summary of the invention
The object of the present invention is to provide and a kind ofly omnidistance can reclaim in instant coffee production process the aroma substance easily scattering and disappearing and destroy, the coffee aroma aqueous solution reclaimed directly is backfilling in liquid coffee concentrate, increase the odor characteristic of liquid coffee concentrate, greatly improve the method and system of aroma substance in the recovery instant coffee production process of the quality of instant coffee.
For achieving the above object, the present invention is by the following technical solutions:
A kind of method reclaiming aroma substance in instant coffee production process, comprise the recovery of aroma substance in Coffee Grinding process, the recovery of extraction process aroma substance, the recovery of enrichment process aroma substance, the aroma substance scattered and disappeared in Coffee Grinding process is reclaimed by the condensation of refrigerating process Water spray, by flash distillation, displacement, concentrate and adsorb the aroma substance reclaimed in extraction process and enrichment process, its concrete grammar is as follows:
The recovery of aroma substance in A, Coffee Grinding process
Get the ripe beans of coffee to be placed in grinder and to grind, the ripe beans process of lapping of coffee can discharge CO
2and Volatile infochemicals, the aroma substance of release is discharged to exhaust outlet through negative pressure transportation with air, collect the air of the carry aroma substances that negative-pressure conveying system exhaust outlet is discharged, after filtration after net filtration, imported in adsorption tower, gas enters in tower from adsorption tower bottom, refrigerating process water is under top spray, gas and refrigerating process water counter current contacting, catch the Volatile infochemicals in gas, and the gas that tower top is discharged enters
