Abstract

The invention relates to the production of soft drinks, in particular to devices for preparing and dispensing soda water with syrup. The purpose of the invention NIN - reducing the loss of carbon dioxide and simplifying the design of the device. In the device for the preparation and batch delivery of soda water with syrup, a volumetric syrup dispenser and a hydraulic drive are installed relative to the metering pump in such a way that the piston of the metering pump through the stops has the ability to move the pistons of the syrup pump and hydraulic actuator, and The metering device communicates with one of the cavities of the hydraulic drive. The design features of the device ensure the simultaneous discharge of soda water and syrup, this work is accomplished by issuing a syrup due to the energy of the water supplied directly via a piston metering pump, that avoids the downcomers mechanisms. In addition, embossing an equal in volume dose of sparkling water from the hydraulic drive cavity into the overflow cavity of the metering pump leads to the fact that no additional carbon dioxide enters the overflow cavity. 1 il.

Description

. The invention relates to commercial engineering and can be used for the preparation and batch delivery of carbonated water with syrup.

The purpose of the invention is to reduce carbon dioxide losses and simplify the design of the device .;

The drawing shows the device

for the preparation and batch delivery of soda water with syrup.

The device contains a metering pump 1, the internal cavity of which is divided by the movable piston 2 into the metering and bypass cavities 3 and 4, the mixing chamber 5 connected by pipeline to the solenoid valve 6 with the bypass cavity 4 of the metering pump 1. The chamber 5 is equipped with a nozzle 7 the inlet channel of which through a check valve communicates with the metering cavity 3 of the pump-to mash 1.

The device also contains

This syrup dispenser is made in the form of a cylinder with a piston 9, which forms the dispensing cavity 10 for the syrup, which is connected by pipelines with check valves 11 and 12 to the syrup tank and the drain pipe. The piston 9 is rigidly connected to the piston 13 of the hydraulic cylinder 14 having cavities 15 and 16, and the cavity 15 is connected to the bypass cavity 4 of the metering pump 1. And the cavity 16 by pipe 17 is connected to the solenoid valve 18 with the metering cavity 3. The piston 13 of the hydraulic cylinder 14 has stops 19, through which pistons 2 and 13 have the opportunity to interact with each other. The device contains a vapor tube 20, inserted into the cavity of the piston rod 2 and communicating the cavity through the solenoid valve 21 with the atmosphere. In addition, the device contains a solenoid valve 22 mounted on the drain pipe, and sensors 23-25, which are affected by the piston rod 2 of the metering pump 1,

The device works as follows. .

The starting point is the average position of the piston 2 of the metering pump 1 and the lowermost position of the piston 9 of the syrup 8 and the piston 13 of the hydraulic cylinder 14. In this case, in cavity 4 there is a part of the dose aerated

a drink, in a cavity 15 - a carbonated drink, and cavities 10 and 16 are minimal.

For soda water with syrup, solenoid valves 6 and 18 are opened by a consumer signal. In this case, the water from the dosing cavity 3 rushes into the cavity 16 of the hydraulic cylinder 14 and moves its piston 13 to the upper position. As a result, the syrup from the tank through the check valve 11 is sucked into the metering cavity 10 of the syrup dispenser 8, and the carbonated water from the cavity 15 of the hydraulic cylinder 14 is displaced into the bypass cavity of the metering pump 1. When the piston 2 reaches the extreme upper position, it acts on the sensor 23, supplying the signal for closing the solenoid valve 6 and opening the solenoid valve 21. At the same time, the gas from the bypass cavity 4 through the gas outlet tube 20 is vented to the atmosphere, and the pressure in the cavity 4 decreases to atmospheric pressure. The piston 2 under the action of the pressure of the water entering the metering cavity 3 from the water supply main starts to lower, tempering the sensor 23. At the same time, the valve 21 closes and the valve 22 opens and the process of discharging carbonated water begins. The piston 2, moving downwards, pushes sparkling water into the drain line, and by means of stops (or stop) 19 moves the pistons 13 and 9 into position. The syrup from the metering cavity 10 of the syrup dispenser 8 is pushed through the check valve 12 into the drain line, and water from the cavity 16 of the cylinder 14 - into the metering cavity 3 of the metering pump 1. Simultaneously, the cavity 15 of the cylinder 14 is filled with sparkling water. When the piston 2 reaches its lowest position, it acts on the sensor 253 to give a closing signal to the solenoid valves 18 and 22 and the opening of the solenoid valve 6. As a result, carbon dioxide enters the pepper chamber 4, under the action of which the piston 2 begins to rise, displaces water from the cavity 3 through the nozzle 7 and the valve 6 into the bypass cavity 4, where it accumulates carbonated water. When the piston 2 reaches the middle sensor 24, the valve 6 closes and the device returns to its original position.

The design features of the proposed device for preparing and batch dispensing carbonated water with syrup reduce carbon dioxide losses and simplify the design of the device by installing a volumetric syrup dosing unit and a hydraulic drive with the possibility of their interaction, as well as the message of the bypass cavity of the dosing pump with one of the cavities hydraulic drive.
