Description

The invention relates to the field of transportation of grapes, production and storage of wines, and can be used in micro-winemaking, farm and personal subsidiary plots.

The following analogs are known from their prior art, coinciding with the purpose of the invention.

Analogue 1. Known device for the production of wines, which is a vertical tank with an internal ledge for fixing the lattice in it. http://wine.historic.ru/books/item/f00/s00/z0000013/st045.shtml

The disadvantage of the device is that it has a more limited scope than the proposed invention.

Analogue 2. It is also known a device for the extraction of pulp and separation of the wort (patent for invention No. 2236445), containing a vertically mounted cylindrical container with pipes, in the inner part of which there is a partition in the form of a flat ring with a cylindrical neck adjacent to the inner surface of the container.

The disadvantages of this device are the complexity of the design, the limited scope of its use - only for the extraction and separation of the wort; the probability of free air access to the wort, which reduces the quality of the future wine.

Prototype. The closest to the proposed installation is made of food grade stainless steel 0.8 mm thick for the production of wines, containing a vertical cylindrical container, a tap for wine selection and a pneumatic floating lid with a check valve to release gases from under the lid and an inflated chamber to fix the lid and prevent air getting under the cover.

https://castavinodelov.com/catalog/vertikalnye_emkosti_dlya_vina_s_plavayushchey_pnevmaticheskoy_kryshkoy_italiya_/5649/

The disadvantages of the known installation are: fragility of the lower part of the container (with a high probability of damage to the thin bottom and the adjacent lower part of the installation under the pressure of the filled contents, and if it is possible that various small objects get under the bottom of the installation during operation and cleaning of the installation); limited uses (only for fermentation and storage of wine); unsuccessful fastening of the tap for wine selection (the fastening of the tap protruding into the container excludes the use of a sieve for draining the wort, collecting and removing seeds, facilitating the discharge of drained mash, as well as efficient mixing of the medium, for example, when pasting wine).

The most probable damage to the lower part of the container leads to a decrease in the quality of the returned wine, or to its loss and the unsuitability of the subsequent operation of the container.

In addition, in this installation, the floating lid is fixed in the container using a pump-inflated chamber made of food grade rubber. The fixed location of the floating lid on the surface of the wine creates inconveniences when the volume of wine changes due to its selection or topping-up, as well as temperature changes: when the volume of wine increases, the wine is partially squeezed out through the check valve. When the volume of wine decreases, the light ball of the check valve does not hold the air flow under the lid. In addition, it becomes difficult to visually determine the volume of wine under the lid. It is quite difficult and ineffective to achieve the light fixation of a light lid by the chamber on the surface of the wine, necessary for free floating, with the help of a pump: there is always air under the chamber, and when the wine is selected, a vacuum is created under the fixed lid, into which air enters the wine through the leaks in the check valve. When fully sealed, air will begin to enter the wine through the tap.

The disadvantage of the known installation is also the increased cost of its manufacture and operation: the presence of a chamber made of food-grade rubber (gusts requiring replacement), a pump (periodic replacement of gaskets, piston lubrication), a pressure gauge (verification, breakdowns) and a check valve (clogging).

In the proposed invention, there are no periodically failing elements that are available in the prototype (pump, pressure gauge, chamber, gaskets), thereby reducing the cost of the invention.

The technical task of the invention is to increase the strength of the installation during operation and cleaning of the installation, to expand the scope of the installation (transportation of grapes), which ultimately leads to an increase in the quality of future wine.

The technical result of the proposed installation

is achieved due to the fact that the design of the installation is made in such a way that the bottom (1) and the lower part of the installation are more durable, since they are made of thicker (compared to the steel thickness of the rest of the cylindrical vertical container from 0.8 mm to 1 mm) food stainless steel from 1 mm to 1.8 mm, which ensures a longer service life and functionality of the entire installation. The height of the bottom of the cylindrical vertical container is from 5 mm to 30 mm. This design makes the container more durable and allows you to significantly increase the reliability of the installation during operation, washing, and transportation of the installation. A distinctive feature of the claimed installation, in addition, is a floating lid (2) immersed in wine with a flexible cuff (3) made of any food-grade elastic material, fixed on the outer side of the raised edges of the floating lid shell along the entire circumference and ranges from 100 degrees to 150 degrees relative the plane of the bottom of the floating cover. The flexible cuff fits tightly to the inside of the container, which excludes the ingress of oxygen from the air into the wine, prevents excessive oxidation of grapes and wine, which ensures an increase in the quality of future wine. The flexible collar can be fixed in any way from materials permitted in winemaking (glue, screws with nuts and food steel wire). For the convenience of moving the floating lid inside the vertical cylindrical container, there are four loops (4) on the inner base of the floating lid for fastening a string or any other flexible attachment (cord, rope, wire).

A floating cover and a sieve (5) with a grip (6) placed in the installation, close in diameter to the diameter of the inner part of a cylindrical vertical container, have movement not only vertically from top to bottom of the cylindrical vertical container, but also rotation in the horizontal plane. A sieve with a grip is used for draining wort or wine material from the mash, effectively mixing the processed wine and effectively removing seeds from the fermenting mash, it is made with a grip in the form of a measuring tube screwed into a nut (7) in the center of the sieve, equal to the height of a cylindrical vertical container. A notched measuring tube serves for approximate measurement of the liquid in the container, and the cruciform ribs (8) located inside the sieve give rigidity to the sieve structure. The sieve grip in the form of a measuring tube is passed through an opening (9) located in the center of the protective cover (10) with a flange (11).

In a cylindrical vertical container, the top of the cylindrical part is reinforced with an enclosing ring made of a square profile (12), on which there are two ears (13) welded to the bottom of the profile, which serve to fasten the cord during transportation and when holding the mash cap. The ball valve (14) is fixed on the branch pipe of the outer cylindrical part of the vertical vessel.

The proposed installation is convenient for use when transporting grapes from the field to the place of wine production, since the cylindrical vertical container has a thickened bottom, it can be filled with carbon dioxide or inert gas, sealed with a floating lid and a protective lid, and the presence of lugs on the enclosing ring made of a square profile allows cylindrical vertical containers between themselves.

Brief description of the drawings.

FIG. 1.Installation with floating roof.

The installation contains a cylindrical vertical container, a protective cover with a hole, with a flange to protect it from dust and dirt, a ball valve for wort and / or wine selection, a floating cover with a flexible collar and hinges.

FIG. 2. Floating cap with cuff.

The floating lid is designed as a flat plate with four hinges at the base and raised edges; on the outer side of the raised edges of the shell of the floating cover, a flexible cuff is fixed along the entire circumference at an angle.

FIG. 3. Sectional view of the installation, sieve with grip.

The installation contains a cylindrical vertical container, a protective flanged lid to protect against dust and dirt, a ball valve for wort and / or wine selection, a sieve with a grip.

FIG. 4. Sieve with a capture.

Sieve with a grip in the form of a measuring tube screwed into a nut in the center of the sieve, with notches for approximate measurement of liquid in a cylindrical vertical container, with a length equal to the height of the container. The rigidity of the sieve is given by the cruciform ribs located inside the sieve.

In a cylindrical vertical container, grapes of technical varieties are transported for from several hours to several weeks, the must is separated from the pulp, the pulp or must is fermented, the wine material is separated from the fermented pulp, the seeds are removed during the fermentation of the pulp, processed (pasted over) and stored.

The invention is illustrated by the following examples:

Example 1. Transportation of grapes. Installed on a pallet, two 300-liter cylindrical vertical containers with floating lids were placed in the body of the Gazelle, having previously fastened them together with any flexible fastener for the ears of the upper rings, and brought to the vineyard. Grape bunches of the Saperavi variety with a mass concentration of sugars of 220 g / dm ^{3 were} loaded in buckets directly onto the field into containers previously filled with carbon dioxide from a cylinder with floating lids temporarily removed from them. After filling the containers pre-installed on the pallet with grapes, it was closed with floating lids, and the containers themselves were fastened to each other by the ears, closed with protective covers and taken to Simferopol, where the cargo along with the pallet was handed over to the transport company for shipment to the Urals. The transport company delivered containers with 0.5 tons of grapes to Orsk in 18 days intact, intact and with improved quality due to prolonged carbon dioxide maceration of grapes at a temperature of 25-35 degrees Celsius.

Example 2. Wort drainage.

Pulp without ridges from Sauvignon grapes was placed in a 300 liter cylindrical vertical container with a previously removed floating lid and a sieve placed on the bottom of the container. A hose was put on the tap fitting and secured with a clamp, the end of which was placed in the lower barrel. After covering the mash with a floating lid and opening the tap, the wort through the sieve, under the action of a column of liquid, rushed through the hose into the barrel. As the floating lid was lowered (wort drainage), it was periodically raised, a new portion of the pulp was added to the container and lowered again to prevent excessive oxidation of the pulp by atmospheric oxygen. After a noticeable decrease in the rate of passage of the wort through the tap, the feed of the pulp into the container was stopped.

Example 3. Fermentation of low-value wort varieties on the drained pulp of elite varieties.

A third of a 300 liter cylindrical vertical container with a previously removed floating lid was filled with leaked pulp of the CitronnyMagaracha variety, an equal volume of Rkatsiteli wort was added and left to ferment under a floating lid to avoid excessive oxidation of aromatic substances by air oxygen. After the formation of a pulp "cap" (noticeable lifting of the floating lid) under the action of the emitted carbon dioxide, the floating lid was replaced with a sieve, with which, using a grip, the "cap" was slightly immersed in a fermenting medium, the grip was passed into the opening of the protective lid, fixing the latter to the top of the container at the same time with fastening the end of the grip of the cord for the ears under the female ring made of a square profile. In the process of fermentation, several times a day, the sieve was slightly lowered and raised by a grip without removing the protective cover. At the same time, the pulp "cap" rose and fell, saturating the fermenting wort with aromatic and extractive substances of the pulp. Upon reaching the desired quality characteristics of the future wine, the fermenting wort was poured through a tap with a hose into a cylindrical vertical container for fermentation,

Example 4. Pasting wine with bentonite

Dry white wine from Bukovinka grapes was filled into an empty (without a floating lid and sieve) 300-liter cylindrical vertical container to 90% of its capacity. The required amount of freshly prepared 5% wine-water suspension of bentonite (5 l), calculated from the results of the test pasting, was introduced, the sieve was lowered on the bottom of the container using a grip, the container was closed with a protective lid, and the contents of the cylindrical vertical container were finally mixed by raising and lowering the sieve grip for several minutes (traditional mixing until uniform

distribution of bentonite particles in wine takes many times longer, which leads to excessive saturation of wine with oxygen). Then they removed the protective cover, removed the sieve from the container by the grip, covered the processed wine with floating and protective covers, and left the contents to clarify for a week alone. After clarification, the wine was removed from the sediment through a tap with a hose into an empty barrel pre-filled with carbon dioxide (to prevent oxidation). In the process of pouring, the floating lid was lowered along with the wine, also protecting the product from the effects of atmospheric oxygen.

Example 5. Storage of wine.

After clarification, dry red table wine from Tavkveri Magarach grapes was placed in a 300-liter cylindrical vertical container, covered with floating and protective lids and left for long-term storage. During storage, small portions of wine were taken through a tap for physicochemical and organoleptic analyzes, for technological needs. At the same time, the floating lid was lowered following a decrease in the level of wine in a cylindrical vertical container, protecting the wine from the harmful effects of atmospheric oxygen. After a year of storage, there were no signs of oxidation in the color, bouquet and taste of unsulphited wine.
