The method of aging of cognac alcohol

 

(57) Abstract:

Usage: the invention relates to food industry, in particular to the technological processes of production of alcohols. The essence of the method of accelerated transformation wine alcohol cognac spirit. The result is achieved by repeatedly increasing the contact area of the wine alcohol with the surface of the oak wood. For this wine the alcohol enter into oak lumber, for example in the form of bars, by centrifuging, and after appropriate exposure soaked in wine alcohol lumber in sealed packages using the centrifugal dehydration allocate the resulting eau-de-vie from oak lumber. Due to the fact that the contact of the wine with alcohol oak wood is at the capillary level, the process of extraction of substances is greatly increased, and therefore, accelerates the transition of wine alcohol in the brandy.

The invention relates to the food industry and, in particular, to a technology for production of ethyl alcohol.

There is a method of aging of cognac alcohol by pouring wine alcohol in oak barrel and holding it in her scheduled time of his cognac spirit. The extraction process is proportional to the surface area of contact of the alcohol with oak wood. During aging in the barrel is the area of its bottom plate and the side wall.

The disadvantage of the above method is a great time necessary for the transition of extrarenal oak in alcohol.

This deficiency is partially removed in the way of aging ethyl alcohol by contact of the wine with alcohol pieces or sawdust of oak wood. In this way the area of contact of the alcohol with oak wood is increased many times, and therefore, accelerates the extraction process.

The disadvantage of this method is that if you reuse oak pieces or sawdust soaked in alcohol, the extraction process is slower.

There is a method of accelerating the ripening of cognac alcohols [1] with the application of accelerators, such as water-alcohol extract of oak wood. The disadvantage of this method is the difficulty, a lot of stages and the energy intensity of the process, the use of chemical compounds, high temperatures.

There is also known a method of production of ethyl alcohol [2], in which the accelerated aging is achieved by a high-frequency processing with inost, and the use of adverse chemical compounds.

The aim of the invention is to reduce the time of extraction of compounds from oak wood in the wine, the alcohol and the reduction of processing ethyl alcohol, excluding the use of chemical compounds, heating.

This goal is achieved by end-to-end impregnation oak timber wine with alcohol in sealed chambers under the action of excess pressure, extracts impregnated timber in sealed containers and subsequent centrifugal extraction of the formed ethyl alcohol of oak lumber.

The proposed method is implemented as follows: alcohol is poured into the sealed chamber of the centrifuge, filled with dry timber of oak, such as bars. The filled chambers impregnation lead through the Central capacity, built-in with internal volumes of the chambers. After filling the free volume of the chambers impregnation with oak beams wine alcohol fill them and the Central capacity. Then disperse the centrifuge to the speed at which the pressure of the column of wine alcohol reaches the value at which is impregnated with alcohol capillar, when alcohol passes through the entire length of the bars.

Then stop the centrifuge, decant through pipelines connecting the camera impregnation with the Central capacity, the remains of the wine alcohol from cameras in the Central capacity. Open the lid cameras impregnation and extract alcohol-soaked oak beams. Put them in sealed bags, for example, of food grade polyethylene and maintain them in a specified time.

It is established that dry oak beams capable of comprehending the impregnation amount of fluid close to the volume of dry bars.

Due to the fact that the contact of the wine with alcohol oak wood occurs at the capillary level in all of the bars, the surface area of the interaction increases, compared with the known methods, many times, and therefore, greatly increases the speed of extraction of substances from wood alcohol.

Soaked in wine alcohol beams of oak after videri re-loaded into the treatment chamber of a centrifuge, seal them and scatter the centrifuge to the speed at which the process of separation of the formed ethyl alcohol. In this mode, stand the time at which the origin Taiwan period of his selection to increase the frequency of rotation of a centrifuge for 5-10% with respect to the frequency, at the beginning of centrifugal dehydration alcohol-soaked oak wood.

Stop the centrifuge and through drain valve drain allocated eau-de-vie from cameras impregnation.

After the removal of ethyl alcohol from cameras impregnation open the valves on the pipes connecting the Central capacity with cameras impregnation, and produce their fill of wine alcohol and repeat all previous operations.

Modes centrifugal impregnation and removal of alcohol from oak lumber depend on their length, location of lumber relative to the axis of rotation of the centrifuge, the original moisture content of the lumber in the first cycle of impregnation and other factors.

Most of them are not amenable to theoretical definition and established experimentally. So impregnation oak bars in an airtight tubes arranged radially relative to the axis of rotation of the centrifuge, occurs when the frequency of its rotation, corresponding to the emergence of the far end of the rod overpressure alcohol in size from 16 to 60 kg/cm2. And the process of centrifugal selection of aged wine alcohol occurs at the frequency of rotation of a centrifuge at which line the show method of producing ethyl alcohol with known methods shows he has significant differences, providing higher efficiency in the production process.

1 Way aging cognac spirit involving the impregnation of timber of oak, alcohol, extract and separating him from oak wood, characterized in that the impregnation and the Department of ethyl alcohol from wood oak is carried out in a centrifugal field, and exposure is carried out in sealed packets.
