Technical field

The technical solution concerns the direct measurement of the withdrawal of cask drinks under pressure (beers, wines, raspberries, milk, etc.), directly on the cushion head of the cask (mobile version) or spatially separated outside the cushion head of the cask (stationary version).

BACKGROUND OF THE INVENTION

At present, there is no accurate direct measurement of keg drinks under pressure in restaurants. Measurement of keg drinks under pressure is solved secondary, simply by weighing the keg itself. Despite its instantaneous weight, the balance of the beverage volume in kilograms is determined, from which the consumption in liters is then calculated. This measurement has several disadvantages:

- the withdrawal of the quantity drawn is not directly displayed but only the residual weight of the beverage with cask,

- the weight measurement is secondary, which is not suitable for the accurate measurement and evaluation of the offtake in relation to the cash register or the introduction of an automated system for the dispensing and control of casks,

- the high weight of a full barrel of approximately 70 kg requires great physical effort by the operator and complicated handling when unloading the scale,

- unloading a heavy drum does not allow careful and gentle handling of the scale, causing shocks that reduce the life and accuracy of the scale,

- when replacing an empty keg and opening a new keg, the residual beverage flows down the weighing pan into the weighing pan and damages it,

- in the light of the above, frequent replacement of damaged scales is necessary.

The essence of the technical solution

These drawbacks in the prior art are fully eliminated by the direct measurement of the withdrawal of cask drinks under pressure in restaurant facilities, which is realized with a sensor and a transducer of an induction flow meter. The essence of the basic version of the device is to place the sensor of the induction flowmeter directly on the hammer head (mobile version) or outside the hammer head (wall, panel with stand), where they are connected to each other by a connecting hose (stationary version). The inductive flow sensor induces the voltage induced by the movement of the cask in the magnetic field. The induced voltage is proportional to the flow rate and volume of the cask drink and the inductive flowmeter with digital display is sensed, amplified and converted to a volume unit that is displayed directly on the display. In an extended version of the device, the inductive flow sensor is supplemented with a main solenoid valve that closes or opens the timing hose with a draft stand. For the entire system to function properly, the induction flow sensor must be vented and filled before the main solenoid valve is closed, and the inductive flowmeter with digital display detects the full pipeline condition, opens the main solenoid valve, collecting and dispensing the cask beverage. Venting and filling of the induction flow sensor in front of the closed main solenoid valve is done by a mechanical vent valve or by an electromagnetic vent valve. The mechanical air vent or solenoid air vent is structurally mounted on a connecting body that connects the flow sensor and the main solenoid valve as close as possible to the main solenoid valve to completely vent and fill the flow sensor and the coupler. A collecting vessel is fitted to the mechanical venting valve or solenoid venting valve which, when venting, retains the beverage after the coupling body has been filled, until the operator interrupts the venting cycle.

Device kits 17:

- the assembly of the device 17 is designed in a single, two-piece and four-piece version (Fig. 9),

- the other assemblies required may consist of the aforementioned designs.

Operation principle 17:

The device 17 is constructed (Figs. 1, 2, 3, 4) and folded consecutively in the following order in the direction of flow of the beverage:

The drum head 13 of the barrel 16 is connected to the front pipe reduction 1 (mobile version) (Figs. 1, 2), or the drum head 13 of the barrel 16 is connected to the front pipe reduction 1 (stationary version) via the connecting hose 14. 4). The front duct reducer 1 is connected to the input of the inductive flow sensor 2. The output of the sensor 2 of the induction flow meter is connected via a connecting body 4 to the main elec- tric

SK 6390 Υ1 solenoid valve 8 and rear pipe reduction 9. Inductive flowmeter sensor 2 with inductive flowmeter converter with digital display forms an inseparable mechanical unit (compact design) (Figs. 2, 4), or they are spatially separately installed (separate version) and interconnected with a connection cable 11 (Figs. 1, 3). A mechanical air vent 5 or an electromagnetic air vent 6 is mounted on the coupling body 4. The inductive flow meter sensor 2 induces a voltage induced by the movement of the cask in the magnetic field, based on Faraday's induction law. The induced voltage responds proportionally to the flow rate, volume, and is sensed by an inductive flow meter 3 with digital display, which amplifies it and converts it to total consumption data, individual consumption data with the possibility of resetting the status and displays them directly on the display. The inductive flowmeter 3 with digital display also detects an empty pipeline condition in which it blocks the measurement of the cask beverage and closes the connection body 4 via the main solenoid valve 8, stops the beverage withdrawal while the distribution hose 15 remains filled with the cask beverage. The detection of empty pipeline status is important in terms of total depletion of beverage from keg 16, where the main solenoid valve 8 can be replaced by empty keg 16. After replacing the keg 16, the induction flow sensor 2 is vented via the connecting body 4 before the main solenoid valve 8 the induction flow meter transducer 3 with digital display detects the full pipeline condition and opens the main solenoid valve 8. Venting and filling of the induction flow sensor 2 and the coupling body 4 is effected via a mechanical air vent 5 (Fig. 1) or via the solenoid vent valve 6 (Fig. 11). The mechanical breather valve 5 or the electromagnetic breather valve 6 is mounted on the connection body 4 as close as possible to the main solenoid valve 8 to completely vent and fill the inductive flow sensor 2 and the connection body 4. For the mechanical breather valve 5 or the electromagnetic breather valve 6, a collecting container 2 is provided which, upon venting, retains the beverage after the induction flow sensor 2 and the connecting body 4 have been filled, until the operator interrupts the venting cycle. The outlet of the main solenoid valve 8 is connected to the rear pipe reducer 9 to which the cask beverage hose 15 is connected. The barrel beverage 15 is the keg beverage supplied to the dispenser rack 18. In the event of a power failure, the assembly of the device 17 is powered from a back-up source 22 so that the keg beverage is dispensed and measured continuously. An important and necessary hygiene action is the technological cleaning of the device 17, the interconnecting hose 14 and the manifold 15 through the dispenser stand 18 and the collecting container 7 itself. For technological cleaning, the main solenoid valve 8, mechanical air vent 5 or solenoid air vent 6 must be open. When the inductive flow sensor 2 is empty and the coupling body 4, i.e. in the basic state, the main solenoid valve 8 is closed and must be opened by the operator via the electric switch 21 of the main valve. The opening of the mechanical air vent 5 is provided by the operator by mechanical movement. The opening of the electromagnetic air bleed valve 6 is ensured by the operator via the electrical switch 20 of the air bleed valve (FIG. 11).

Selection of the suitable pipe diameter of the induction flow sensor 2

A very important part of the design is the design of the pipe diameter of the sensor 2 of the induction flowmeter corresponding to the flow rate according to the assumed mass flow of the cask beverage. Manufacturers declare the range of the sensor 2 of the induction flow meter about 0.1 - 10 m / s. The essence of the ideal technical solution is to propose, according to the flow rate of the beverage, the same pipe diameter of the induction flow sensor 2, the connecting hose 14 and the distribution hose 15, thereby eliminating the disturbing effects of the vortex streams of the beverage for sensing the flow rate. drink. The design and design itself must comply with the installation and operating instructions of the manufacturer of the inductive flowmeter 2 and the inductive flowmeter 3 with digital display.

In the following chapter is a simplified sample procedure for calculating the flow rate for cask beer and for the individual pipe diameters of the induction flow sensor 2. From the above overview (Table 1) it can be seen that the declared range of the sensor 2 of the induction flow meter of about 0.1-10 m / s complies with the pipe diameter up to DN10. The ideal technical solution is to match the pipe diameter of the induction flow sensor 2 on the market to the standard DN6 of the connecting hose 14 and the distribution hose 15. Simplified calculation of the flow rate for beer:
