The invention relates to food industry, in particular to a method of cleaning beverage adsorbent, and can be used for cleaning liquors, alcoholized juices, fruit drinks, wines and soft drinks containing phenolic compounds and dissolved oxygen.

Known methods of purifying beverages adsorbent, in particular activated carbon, providing the contacting activated carbon with a processed beverage [1].

Known methods closest to the proposed technical essence is a method of cleaning beverage adsorbents in two stages, the first of which enters the adsorbents in the processing of the drink, but on the second or final cleaning at the tangential entry of the mixture in the same drink with the adsorbent; Department last drink from circulation and enter it in the process of cleaning and removing clarified liquor.

However, the known method does not provide the stability of the drink is to be placed is to increase the stability of the finished product due to the purification from phenolic compounds and prevent oxidative processes.

For this purpose, the method of cleaning beverage in two stages, the first of which enters the adsorbent in the processing of the drink; but on the second or final cleaning at the tangential entry of the mixture in the same drink with the adsorbent, separating the latter from the drink with the circulation and enter it in the process of cleaning and removing clarified drink, take away part of the drink with the adsorbent, mix this mixture with part of the original drink under vacuum and provide continuous circulation in selected drink with adsorbent with speed, ensuring that the adsorbent in the drink in pseudocyesis condition, at the same time separate the adsorbent from the drink and lighten separated beverage filtering.

It should be noted that this set of features is significantly new and provides for the achievement of this goal.

First, the proposed method used the repeated mixing of the drinks from the adsorbent and a fresh drink under vacuum and continuous circulation in selected beverage under pressure with speed, ensuring that the adsorbent in the state of pseudocumene when the intensity of feeding, not exceeding update volume obrabotati phenolic compounds and the release of dissolved oxygen, which ultimately leads to increased stability of the finished product, as it inhibits oxidative processes.

Selection of speeds, ensuring that the adsorbent in pseudocyesis condition and separating him from drink for pre-exposure prior to filtration, is the hydrodynamic retarding the flow of drink vertically through the selection of the drinks with the adsorbent, mixing this mixture with part of the original drink in the ratio of 6:1 under vacuum in continuous circulation in selected drink with adsorbent with speed, ensuring that the adsorbent in the drink in pseudocyesis condition.

It is known that the composition of alcoholic beverages include teas, juices, fruit drinks and other semi-finished products containing high-molecular compounds. These compounds include proteins, pectins, condensed polyphenolic compounds, etc. with high adsorption capacity and seeking to aggregation of particles. The result of turbidity, accompanied by the formation of precipitation, reducing the stability of drinks and their quality.

To lengthen the duration of the storage of the beverage without the formation of sludge used P CLASS="ptx2">

At the stage of preliminary processing when contacting the beverage with the adsorbent on its surface due to the occurrence of ties adsorbed portion of the phenolic compounds, which after settling with the sorbent is removed from the beverage filtering.

Removal of dissolved oxygen from the drink is made by vacuum.

As a result of the processing is a slight reduction in the concentration of phenolic complexes and dissolved oxygen, which slows down the oxidation process and prevents precipitation and dramatically increases the stability.

The method is as follows.

In the first stage enters the adsorbent in the processing of the drink, and the mixture is selected and serves tangentially into the working chamber containing the same drink with the adsorbent. Begin the second stage of purification, at which the selected part of the drink with the adsorbent of the working chamber, mix this mixture with part of the original drink in the ratio of 6:1 under vacuum and continuously circulating in selected drink with adsorbent with speed, ensuring that the adsorbent in the drink in pseudocyesis condition. When this happens otterlei after the preliminary exposure. After this drink take in the collection of the finished product.

P R I m e R 1. Take alcoholized Apple juice fortress 25% by volume content of extractives of 9.8 g/100 ml in the number of 28.0 gave and complexing sorbent in the amount of 0.5 kg, derived from N-vinylpyrrolidone permitted for use by the Ministry of health of the USSR.

In the first stage of purification in the working chamber of the apparatus is poured 28,0 gave Apple juice and injected with 0.5 kg of sorbent, mixed and kept in active contact within 6 minutes

In the second stage, the final cleaning is as follows. From the working chamber are selected with the speed of 720 dal/h drink with adsorbent and injected into the mixer, in which simultaneously serves fresh drink without adsorbent with a speed of 280 dal/hour Drink with the adsorbent is passed through the mixer and then with a speed of 1000 dal/h return tangentially into the working chamber in the original drink with adsorbent with 36 cycles 1/h In the mixing process occurs deaeration of the mixture under vacuum, equal to 40 kPa.

Speed 1000 dal/h contributes to the maintenance of the sorbent in the drink in pseudocyesis state with a linear velocity of 0.01 m/s After mixing deaerated drink handle and served in the collection of the finished product. The results are shown in table.1.

P R I m m e R 2. Perform in example 1, only as a source of drink is drink "cherry" fortress 14%. The results are shown in table.2.

P R I m e R 3. Perform in example 1, only as a source of drink is vodka, and as an adsorbent for comparison, coal BAU-A. the Results are shown in table.3.

Higher alcohols decreased from 4 to 3 mg/DM3. According to the results of chromatographic analysis of N-3 extracted from the sort aldehydes: propionic, acetic acid, esters include methyl acetate, ethyl acetate, methanol.

Improved organoleptic properties associated with the absorption of sorbent P-3 from the sorting of higher alcohols, aldehydes, esters. The absorption of higher alcohols is due to the complexation between electronegative carbonelli oxygen-lactam ring and the hydroxyl hydrogen of the alcohol. Aldehydes and esters, solvated in aqueous-alcoholic solution, enter into complex formation with the carbonyl oxygen lactam ring by hydrogen hydrate shell.

P R I m e R 4. Perform in example 1, only as a source of drink is bezalkogol the raw juice, drink is the best, because this ratio changes the processing mode, which leads to the change of physico-chemical parameters. If this ratio is less than 6:1, for example 4:1, then decrease the processing efficiency of the sorbent and the target (stability), thus reducing the sampling below critical, phenolic compounds.

If the ratio is more than 6:1, for example 8:1, it is excessive handling sorbent. Consequently taken more than necessary, the amount of phenolic compounds, which leads to a change of color, but does not increase the duration of storage.

Well-known [2] for purifying beverages adsorbent containing a collection of raw drink, the working chamber for mixing the drink with an adsorbent having a nutritious and discharge nozzles, coolant reservoir mounted in the chamber, and the collection of the finished product.

However, processing at this facility does not provide long-term storage of the drink and its deaeration, use and regeneration of the sorbent synthetic (organic) origin.

The aim of the invention is to increase the stability of the finished product for scheelhaase installation, General view of Fig.2 - design of the vacuum mixer.
