Description

eleven

The invention relates to the food industry, in particular, to devices for preparing and batch dispensing carbonated water.

The purpose of the invention is to improve the quality of the beverage without increasing gas loss by stabilizing the hydrodynamic conditions of mass transfer and increasing the contact time of the phases.

The figure schematically shows the ycTpoficTBO for the preparation and distribution of soda water.

The device for the preparation and batch delivery of sparkling water contains a dosing pump 1, the internal cavity of which is divided by the movable piston 2 into the dosing 3 and the overflow 4 cavities. on the axis of the base 6 on its surface there is a mixing body in the form of a nozzle 7. The piston is provided with a reflector 8 located on its lower surface & coaxially with the nozzle 7, and the bottom surface of the piston corresponds to the shape of the bottom of the bypass cavity, which embraces it. The dosing cavity 3 is connected, through a check valve 9 and the water cooler 10, to the water supply pipe 11 and through the solenoid valve 12 to the overflow cavity 4.

The device also contains a pipeline 13 for dispensing a beverage with a solenoid valve 14 and a throttle 15, a gas supply pipe 16 with a solenoid valve 17 and sensors 18 and 19, which are affected by the piston rod I of the piston 2 o

The device works as follows.

The starting point is the extreme upper position of the piston 2. At this point, in the overflow post 4, there is a dose of carbonated water. A solenoid valve 14 opens at the consumer’s signal to dispense the beverage. After the action of the free gas pressure in cavity 4, the solenoid valve 14 is opened through the salt valve 14 and the choke 15 is dispensed to the consumer. / Addition in cavity 4 falls, and piston 2 under action71592

The pressure of the water entering the cavity 3 from the water cooler 10 starts to move downwards. In its lowest position, the piston 2 acts on the sensor 18, which sends a signal to close the valve 14 and open the solenoid p, valves 12 and 17, As a result, cavity 4 begins to flow a gas and between the cavities 3 to 4 a pressure differential O is created, under the action of which the water from the cavity 3 through the solenoid valve 12 and the nozzle 7 rushes into the cavity 4.

The water jets emerging from the nozzle 5-7 hit the reflector 8 and are crushed into droplets that rush into the gap between the bottom surface of the piston and the protrusion. Thus, the fluid leaving the nozzle passes through the gaseous medium to the reflector,

is crushed into droplets, which are then moved by the gas from the reflector to the layer of sparkling water accumulated in the lower part of the cavity 25 4 "The piston 2 moves to the extreme upper position and acts on the sensor 19, which gives a signal to close the valves 12 and 17, the device returns to its original state. 30 The location of the nozzle nozzle above G1 of the liquid level in the bypass cavity stabilizes the operation of the nozzle, since the liquid accumulating in this cavity does not prevent J2 from flowing out of the water jets. The reflector mounted on the lower surface of the piston contributes to splitting the jet into droplets and increasing the mass exchange surface. In the proposed device, a fresh fluid flowing out of the nozzle passes in the gaseous medium from the nozzle to the reflector and from the reflector to the lower part of the bypass cavity forming the lower j of the piston surface, without mixing with the saturated liquid. This allows stabilizing the hydrodynamic conditions of the nozzle operation, increasing the mass-sharing surface, phase contact time and the average driving force of the mass transfer process, which contributes to the growth of the carbon dioxide dissolved in the finished beverage, which determines the quality of the carbonated beverage.
