Description

The invention relates to equipment for the food industry, in particular for the fermentation of kvass, mead, beer and other fermentation products.

Known fermentation apparatus for fermentation of kvass wort (Rudolph V.V., Balashov V.E. Production of soft drinks and bottling of mineral water. P. 255 - M .: Agropromizdat, 1988) [1], which are metal tanks of various designs, equipped with coils for cooling the wort and decanters for removing the fermented wort from the yeast sediment. At the bottom there is a fitting for draining the wash water. Stirring of the wort in the fermentation apparatus is carried out by pumping it “to yourself” or using portable propeller mixers.

Fermenters are equipped with pipelines for the supply of kvass wort, sugar syrup, yeast, fermented milk and water, hermetically sealed lids and pipes for the removal of carbon dioxide released during fermentation.

The most progressive type of equipment for the fermentation of kvass wort is fermentation and blending machines and cylinder-conical tanks.

The fermentation and blending apparatus (ibid., P. 255-257) [2] is a cylindrical tank with a conical bottom and a spherical lid, on which there is a hermetically sealed hatch. For heating or cooling the fermented wort and the finished kvass, the apparatus is provided with a jacket. At the bottom of the conical bottom there is a yeast separator overlapping by a flap.

To mix the wort during fermentation and blending, the apparatus is equipped with a stationary propeller mixer. The device is mounted on supports. Its main advantage is the possibility of combining the cooling processes of wort and kvass, fermentation of wort, separation of yeast, blending of kvass.

A brine with a temperature of -10 ÷ -15 ° C is supplied under a constant pressure of 0.08-0.1 MPa, which is controlled by a pressure gauge. Fermentation and blending machines are manufactured with a capacity of 100, 500 and 1000 dal.

The cylindroconical tanks with a capacity of 25,000 or more gave structurally almost no different from fermentation and blending devices.

Most cylinder-conical tanks (Kuntze V., Mit G. Technology of malt and beer: transl. From German p. 409-410 - St. Petersburg, Publishing House "Profession", 2001) [3] used at the enterprises are a tank with a diameter of 3.5 m to 4.5 m. The ratio of the diameter of the cylindrical part of the tank to the total height of the wort should be 1: 2. In addition, the cylinder-conical tank should have a free space for foam up to 25% of the volume of the initial wort. Thus, the cylinder-conical tank has a rather large height, and therefore it is very common to install it outdoors.

For the prototype we took a fermentation and blending device for fermentation of kvass wort [2].

The disadvantage of the above constructions of the fermentation apparatus is their structural complexity and the large size of the fermentation tanks designed for industrial volumes of production of fermented beverages, all of them are stationary, and a separate room is required for their installation.

The aim of the invention is to simplify the design of the fermentation apparatus for fermentation of wort and the possibility of using it for the production of fermented beverages in volumes up to 20 decalitres. The advantages of the proposed design of the fermenter over analogues are: its small size (it does not require a separate room) and mobility.

The inventive fermenter for fermentation of the wort is a structure consisting of a fermentation tank with a lid and a bottom, equipped with a drainage device. In the upper part of the fermentation tank there is a filler neck, which is closed by a lid, and in the lower part there are two drain taps installed on the side surface of the tank at different heights: one above the other at a distance of at least 15 cm with horizontal displacement relative to each other. The lower tap is installed in close proximity to the bottom of the tank and is designed to drain precipitated yeast, the upper - to drain the finished drink. To maintain the temperature of fermentation in the fermentation tank within the limits according to the technological process of production of the drink, for example 30-35 ° C, there is a heat heater mounted around the fermentation tank. The temperature mode of the heater is supported by the control unit and power supply.

This block is made of insulating material, for example polystyrene, in the form of a cylindrical hollow lid and mounted on a fermentation tank. On the external surface of the control and power supply unit (cover), a block of electronic transformers and an electronic relay-regulator is installed. Inside the lid, the connections of devices installed on the outer surface of the lid were mounted. The control and power supply unit is connected by an electric wire to a temperature sensor inserted through the hole in the filler cap of the fermentation tank into the fermented wort, by a cable - with an heating pad and an electric cord with a power supply network.

The drawing shows a fermentation apparatus for fermentation of wort, where:

1 - fermentation tank;

2 - filler neck with a lid;

3 - temperature sensor;

4, 5 - cranes;

6 - heat electric heater;

7 - a fastener;

8 - control unit and power supply;

9 - block electronic transformers;

10 - electronic relay regulator;

11 - electric wire;

12, 13 - cable;

14 - an electric cord with a plug;

15 - connector.

The fermentation tank 1 is made of a material certified for food storage, for example, polyethylene, has a cylindrical shape and a volume of less than 20 decalitres, in the upper part of the tank there is a filler neck 2, which is closed by a lid made of material intended for contact with food products. In the center of the lid there is an opening for introducing the temperature sensor 3 into the fermented wort.

In the lower part of the fermentation tank, there are two taps on its lateral surface: the lower tap 4 is used to drain the precipitated yeast, the tap 5 is used to drain the finished kvass, located at a distance of at least 15 cm above the previous one with a horizontal or horizontal shift to the right or to the left convenient for draining.

In order to maintain the fermentation temperature in the fermentation tank 1, for example, within the range of 30-35 ° C, a low-voltage heat electric heater 6 is designed, made using heating technology, for example, for a car seat. The fermentation heater 6 wraps the fermentation tank 1 and fixes its position with a fastener 7, maybe Velcro.

A control and power supply unit 8 is installed on the fermentation tank 1. This block is made in the form of a cylindrical hollow cover made of insulating material, for example, polystyrene, with devices installed on its surface: an electronic transformer unit 9 and an electronic relay-controller 10; installation of connections of devices installed on its outer surface. An electric wire 11 connects the control and power supply unit 8 to a temperature sensor 3 inserted through a hole in the filler cap 2 into the fermentation tank 1 for contact with the fermented wort. Cable 13 is designed to connect the control unit and power supply to the heat heater 6, an electric cord with plug 15 is used to connect the control unit and power supply to the power supply network. The power of the heating pad (heat heater) is carried out with a voltage of 12V, which does not have contact with the wires of the 220V network.

Filling the fermentation tank 1 with wort is carried out through the filler neck 2 with closed taps 4 and 5. After filling the fermentation tank with wort, the filler neck is closed with a lid. The fermentation tank 1 is wrapped with a heat heater (heating pad) 6, the position of the heating pad is fixed with a fastener 7. A temperature sensor 3 is inserted into the wort through a hole in the filler neck cover 2. A control and power supply unit 8 is installed on the fermentation tank 1. A heat heater 7 is connected to the control unit via connector 15 and power supply 8. The control and power supply unit 8 is connected to a 220 V power supply network. The temperature regime necessary for fermentation is set on the electronic relay-controller 10, for example p, within 30-35 ° C. Fermentation of the wort is carried out during the time established by the technological process for the production of a fermentation drink.

At the end of the fermentation time set by the technological process for the production of the beverage, the fermentation apparatus is disconnected from the 220 V electric network. The control unit and power supply unit 8 are removed from the fermentation tank 8, the temperature sensor 3 is removed from the wort. The heater 1 is removed from the fermentation tank 6. Fermentation tank 1 with the fermentation product placed in a refrigerator to precipitate yeast. Cooled to a temperature of 6-10 ° C, the finished drink is drained through the faucet 5. At the end of the draining of the finished beverage through the faucet 4, precipitated yeast is drained for disposal.

A fermenter for wort fermentation with a volume of up to 20 dal is intended for the production of fermented beverages (e.g. kvass, mead, beer) by catering enterprises, individual entrepreneurs for sale to the population through a distribution network, as well as for the manufacture of these drinks at home.

The advantages of this fermentation apparatus are also the low-voltage power supply of the heaters and the presence of two taps that allow the precipitated yeast to be drained separately from the finished drink.

Currently, the manufacture of the inventive fermenter for fermentation of wort mastered by the applicant and is successfully used in the technological process of production of kvass.
