The concentrates preparation device of the invention includes a depressurization process, a condensing process, an accumulating process, a draining process and a sampling process.

Depressurization process io Switching off the first, fourth and sixth water valves 25, 22, switching on the second, third, fifth, seventh, eighth and ninth water valves 24,23. Turning on the depressurization unit 4 to make the air in the boiler pass sequentially through the fifth, second, third and ninth water valves 24, 23 into the depressurization unit 4 so as to decrease the air pressure in the boiler.

Condensing process Turning on the cooling unit 3 to make cooling liquid thereof loop sequentially through the seventh water valve, the top ring, the bottom ring and the eighth water valve, the temperature of the top cover of the boiler is 20 less than the temperature of the hot steam in the boiler with the help of cooling liquid. Turning on the heating unit 12 in the boiler to increase the temperature of the mixture therein, the boiling point of water in the mixture is decreased under the low air pressure in the boiler, so the water can be boiling at low temperature to produce hot steam, which condenses 25 into water drop when touches the bar confluence rod 1103 with lower temperature with respect to hot steam, water drop slides into the confluence chamber along the first or second arcuate surface 1103b, 1103c 12/19 with the help of cooperation between overflow prevention edge 1103d and surface tension of water drop, the confluence chamber collects water drop slid from the bar confluence rod 1103. Through the condensing process, water in the mixture in the boiler is continuously transferred into the confluence chamber so as to decrease the content of water in the mixture.

Accumulating process When water level in the confluence chamber is over the interior duct opening of the output duct 1105, through which water is drained into the io accumulator unit 2, water passes sequentially through the fifth water valve and the second water valve 24, there are three conditions in the accumulating process: L the air pressure in the boiler is greater than the air pressure in the accumulator unit 2; 2. the air pressure in the boiler is equal to the air pressure in the accumulator unit 2; 3. the air pressure in the boiler is is less than the air pressure in the accumulator 2.

When in condition 1, water in the confluence chamber is compressed into the accumulator unit 2 by the air pressure.

When in condition 2, water in the confluence chamber flows into the accumulator unit 2 under the gravity force, because the confluence 20 chamber is above the accumulator unit.

When in condition 3, turning on the depressurization unit 4 to decrease the air pressure in the accumulator unit 2 and make it less than the air pressure in the boiler, such that the condition 3 is changed to condition 1 or condition 2; the accumulator unit 2 accumulates water through above three 25 methods.

Because the heating unit 12 in the boiler is heating, the temperature in the 13/19 boiler is greater than the temperature in the accumulator unit 2, so the air pressure in the boiler is greater than the air pressure in the accumulator unit 2, thus, heating is good for condition 1.

When the density of the concentrates reaches the predetermined-density, the heating unit 12 stops heating, the air pressure in the boiler is decreased, turning on the depressurization unit 4 for avoiding that the air pressure in the boiler is less than the air pressure in the accumulator unit 2, the air pressure in the accumulator unit 2 is less than the air pressure in the boiler io through the depressurization unit 4 so as to compress the water condensed from the rest steam into accumulator unit 2. Because the water level in the confluence chamber is above the interior duct opening of the output duct 1105, steam in the boiler do not directly pass into the accumulator unit 2 so as to reduce bad impact from steam to the depressurization unit 4; because 15 the interior duct opening of the second duct 29 is near to the bottom portion of the barrel 21, and the interior duct opening of the third duct 28 is near to the top portion of the barrel 21, it is avoided that water compressed out of the second duct 29 is immediately inhaled into the third duct 28 when the depressurization unit 4 works, such arrangement that the interior 20 duct opening is arrange to the top portion of the barrel 21 can reduce the risk of water in the barrel 21 passing into the third duct 28.

Draining process When the water level tagging pipe 26 displays that the water level reaches 25 the predetermined-density, the second water valve 24 is turn25 off firstly, because the second water valve 24 acts together with the third water valve 23 through the connecting block 24, the third water valve 23 is turned off 14/19 when the second water valve 24 is turned off, from then on, water condensed in the boiler is stored by the confluence chamber provisionally, the accumulator unit 2 is isolated from the boiler after the second and third water valves 24,23 are switched off; the fourth water valve 22 is switched 5 on for an equal air pressure between the accumulator unit 2 and the outside atmosphere, the first water valve 25 is switched after achieving the equal air pressure, water in the accumulator unit 2 flows out from the first water valve 25 due to the gravity force, the draining of accumulator unit 2 is achieved. io After water in the accumulator unit 2 is drained off, the first and fourth water valves 25,22 are turned off firstly so as to isolate the accumulator unit 2 from the outside atmosphere, after that, the second water valve 24 is turned on secondly, meanwhile the third water valve 23 is turned on too, because the air pressure in the accumulator unit 2 is greater than the air is pressure in the boiler, water in the duct is compressed back to the boiler at the time when the second and third water valves 24,23 are turned on, water is kept in the confluence chamber rather than flows into the concentrates due to the buffering effect of the confluence chamber. When the air pressure in the accumulator unit 2 is equal to the air pressure in the boiler, 20 condensed water provisionally stored in the confluence chamber flows to the accumulator unit 2 under the gravity force. The depressurization unit 4 is switched on for keeping a low air pressure condition in the boiler so as to keep the air pressure at a predetermined-density, switching on the depressurization unit 4 speeds up water in the confluence chamber flowing 25 to the accumulator unit 2.

After the density of concentrates in the boiler reaches the /19 predetermined-density, the heating unit 12, the depressurization unit 14, the fifth water valve and the sixth water valve are switched off firstly, air from the outside goes into the boiler through the gas inlet duct 1108 so as to make the air pressure in the boiler be equal to the outside air pressure, 5 the present air pressure in the boiler is greater than the beginning of concentrating, the boiling point of water in the concentrates increases accordingly. Because the heating unit 12 is turned off, water in the concentrates do not boil any long, the concentrates do not loose water any more, that is the present density is kept. io Opening the discharging opening 16 to let the prepared concentrates flow out from the discharging opening 16, which is switched off after the concentrates is drained off. Opening the feeding opening 15 to let the mixture unconcentrated flow into the boiler, the feeding opening 15 is switched off when the mixture reaches the predetermined-density to is isolate air in the boiler from the outside atmosphere for the next concentrating process.

Obviously, water in the accumulator unit 2 can be drained out during the boiler is inputting mixture or outputting concentrates. The detailed process 20 is that, the ninth water valve is switched off firstly, then the sixth water valve is switched on, due to the pressure difference water in the confluence chamber is compressed to the accumulator unit 2; after the air pressure in the accumulator unit 2 and in the boiler is equal to the air pressure of the outside atmosphere, water in the confluence chamber flows to the 25 accumulator unit 2 under the gravity force, meanwhile the first water valve is switched on for draining of water from the accumulator unit 2. 16/19 The depressurization unit 4 is an air extracting pump or a vacuum pump. The cooling unit 3 is provided with an input end and an output end, the cooling liquid flows into the cooling unit 3 from the input end, the cooling fin of the cooling unit 3 takes heat away from the cooling liquid into the 5 atmosphere so as to make the temperature of the cooling liquid from the output end of the cooling unit 3 cooler than the temperature of the cooling liquid from the input end of the cooling unit 3.
