Description

The utility model relates to the cooling of liquid products and can be used in the baking industry, in particular for cooling the tea leaves in the production of bread and bakery products.

A device for cooling liquid products, mainly milk, containing a cooler tank with a water jacket connected to a water tank, a pipeline for supplying heated water with an nozzle located above the tank, a pipe for draining chilled water connected to the tank in its lower part, means for maintaining a given level of water in the tank and comprising a float valve, the chamber of which has an inlet and outlet nozzles and through the first of them is hydraulically connected to

water source, and through the second - with the bottom of the tank. In this case, the float valve contains two locking elements for blocking the inlet and outlet pipes. The water tank is located outside the milk unit and is designed to work in conditions of subzero temperatures, so the device as a whole is capable of simultaneously producing milk cooling and freezing of the ice rink in winter. (1).

However, this device, due to the peculiarities of its design, caused by specific operating conditions, including at subzero temperatures, cannot be used in the baking industry, since the preparation of the tea leaves does not require a deep degree of cooling, and the water used for household needs have a temperature of at least 20 ° C.

A device for cooling a liquid tea leaves for preparing dough is also known, comprising a working container with a jacket, a pipeline supplying cold water to the jacket, and a pipeline diverting the heated water to the sewer. The flow rate of cooling water having a temperature of 15 ° C per serving of infusion is 580 liters per minute. (2).

The disadvantage of this device is the presence in the sewer suitable for technical needs water.

2 The closest in technical essence and achieved

the technical result and the claimed is a device for cooling the tea leaves used to prepare the dough, which is selected as a prototype. (3)

The device contains a storage tank of the source water, the working capacity of the brewing machines with water jackets, connected pipelines and having them; nozzles for draining heated water into the sewer.

This device has the same drawback, namely, when it is used, there is a significant discharge into the sewer suitable for technical needs and repeated household consumption of heated water.

It became possible to solve the problem of eliminating the existing, its lack of device, by creating a closed loop of water treatment; an application in which multiple use of heated water is provided.

The technical result of the utility model - reducing water consumption for technological needs is ensured by the fact that the device is equipped with an additional water flow control unit and a heated water tank that is hydraulically connected at the inlet through the collector with the inlet of each shirt of the working capacities of the brewing machines and through a pump with a source water tank at

In this, in the collection tank of the heated water, level electrodes are installed, connected to the input of the water flow control unit, which is connected with the pump electric drive by its output.

The drawing shows a device for cooling a liquid semi-finished product for kneading dough.

The device comprises a storage tank 1 of source water, connected by pipelines 2 having valves 3, with shirts 4 of working capacities 5 of brewing machines. All working tanks at the outlet 6 are connected through a collector 7 to a tank-collector 8 of heated water, which through a pump 9, a pipeline 10 is connected to the storage tank 1 of the source water. In the collection tank 8 of the heated water, electrodes are installed and level meters I and 12 are connected to the input of the water flow control unit 13, the output of which is blocked with the electric drive of the pump 9. The flow of water into the storage tank 1 and consumption for household needs are indicated by arrows 14 and 15, respectively .

The device operates as follows; in their image.

Water from the storage tank 1 enters through pipeline 2, through open or all open valves 3 into the shirts 4 of the working capacities of 5 brewing machines, taking heat from the liquid semi-finished product in them, particularly the brewing, and then through outlet 6, the collector 7 is sent to storage tank 8 of heated water, where it takes place

accumulation and simultaneous cooling. As soon as the water level in the tank 8 from the measuring electrode 11 reaches the electrode 12, a signal is supplied to the water flow control unit 13, after which the electric drive of the pump 9 is turned on, which pumps water to the storage tank 1. When the level decreases relative to the electrode And the command about this also enters the control unit 13, which turns off the pump 9. In the case of water consumption for household needs through the pipeline 15, a means is switched on to maintain the desired storage in the storage tank 1 (not shown in Fig.) and About the pipeline 14, it is filled from the existing water supply with a temperature of no higher than 15 ° C. During the next brewing, the cycle of operation of the device for cooling the liquid semi-finished product for kneading the dough is repeated again.

The specified device compares favorably with the known ones in that the water consumption for cooling the tea leaves, which is ultimately used in the process for kneading the dough, is significantly reduced. So, when using this device for cooling a liquid semi-finished product on 3 brewing machines of KhMZOO, which ensure daily production of up to 30 tons of bread and bakery products, about 1,500 cubic meters of water are saved monthly, which in monetary terms at a total cost of 1 m equal to 10 rubles will be about 15,000 rub. savings. In addition, the accumulation of heated water in the storage tank 1 in

the process of its circulation in a closed circuit does not have a noticeable effect on the rate of heat extraction from the mass of the liquid semi-finished product located in the working capacities of the brewing machines at a temperature of 9092 ° C, but the increase in water temperature as a working medium leads to heat savings and a reduction in the time of its additional heating up.
