Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a system for reusing steam in a beer manufacturing process, and particularly to a system for reusing steam generated during a wort boiling process.

``Conventional technology'' In the boiling process during the beer manufacturing process, boiling pot 1 is used.
By adding hops to the wort and boiling it using steam, the protein coagulates and the hop flavor is extracted.

Therefore, the boiling process is an important process that determines the taste of beer. If the amount of wort boiled at this time is about 100 tons per batch, a large amount of steam, about 11 tons per batch, is inevitably required, but if you try to supply all of this large amount of steam from the boiler, Since the operating cost is extremely high, about 10 tons of steam generated from the boiling pot 1 per batch is recompressed by the compressor 2 and used for heating the boiling pot 1.

"Problems to be Solved by the Invention" At this time, as a drive source for the compressor 2, a gas turbine or the like 7 is used to impart rotational force to the compressor 2 in order to effectively utilize energy. Because the boiling process is not continuous operation due to its nature but is batch operation, the compressor 2 must also be operated intermittently, and during this time the gas turbine etc. 7 must be operated intermittently.
will stop and the drive efficiency will be extremely poor.

In view of the drawbacks of the prior art, it is an object of the present invention to increase the driving efficiency of the gas turbine 7 and to utilize it effectively even when the compressor is intermittently operated.

"Means for Solving the Problems" In order to achieve such technical problems, the present invention provides a gas turbine or the like 7 that applies rotational force to a compressor 2 that compresses steam generated from a beer boiling pot 1, and a generator. The present invention proposes a steam reuse system in a beer manufacturing process, which has an essential component in which a compressor 2 and a compressor 2 are connected through at least one clutch means.

"Operation" According to this technical means, during the boiling process of the wort boiling pot 1, the driving force of the gas turbine etc. 7 is transmitted to the compressor 2, thereby smoothly compressing the steam generated from the wort boiling pot 1. This leads to saving of steam for heating the boiling pot 1. In this case generator 1
2 performs no-load operation without power generation, and simply rotates only the internal rotor, so that the rotor functions as a flywheel and the gas turbine etc.
This leads to a reduction in vibration of the compressor 2.

Of course, if the driving force of the gas turbine or the like 7 is greater than the energy consumption of the compressor 2, it is also possible to operate the generator 5 under load to generate electricity.

In addition, by using an induction motor as the generator 5, when the driving force of the gas turbine etc. 7 is smaller than the energy consumption of the compressor 2, the induction motor is auxiliary driven, so that the compressor 2 runs smoothly. Able to drive.

On the other hand, during the non-boiling process, the compressor 2 is separated by the clutch means 4, and the driving force of the gas turbine etc. 7 is transmitted only to the generator 5. By using the power source for various devices in the factory such as the malt crushing device and the filter tank, it is possible to significantly save commercial power source and to greatly improve the driving efficiency of the gas turbine etc. 7.

"Embodiments" Hereinafter, preferred embodiments of the present invention will be described in detail by way of example with reference to the drawings. However, the dimensions, materials, shapes, relative positions, etc. of the components described in this example are as follows, unless otherwise specified.
This is not intended to limit the scope of the invention, but is merely an illustrative example.

The drawing shows a beer wort boiling process in an embodiment of the present invention.

In this figure, 7 is a gas turbine or the like driven by fuel gas, and a generator 5 with a clutch means 6 functioning as an induction motor, a transmission 3 having a clutch means 4, and a compressor 2 are connected in series on the output shaft side of the gas turbine. The steam generated from the boiling pot 1 is introduced into the compressor 2, and after being compressed by the compressor 2, it is introduced into the boiling pot 1 again, and after being used for heating the boiling pot 1, it is subjected to other heating steps. used.

Further, when the wort is not boiled in the boiling step, the clutch means 4 of the transmission 3 releases the connection between the generator 5 and the compressor 2, and the gas turbine etc.
Only the generator 5 is rotated using the driving force of the generator 5, and the electric power obtained from the generator 5 is used as a power source for the beer manufacturing process and other various devices in the factory.

On the other hand, the exhaust gas obtained during the operation of the gas turbine 7 and the like is led to the boiler 8, and the steam obtained thereby is used as a heating source for other beer manufacturing processes.

"Effects of the Invention" As described above, according to the present invention, since the compressor and the gas turbine etc. are connected in series via the generator and the clutch means, when the compressor is in intermittent operation, It also has various remarkable effects, such as increasing the drive efficiency of gas turbines and the like, increasing thermal energy efficiency, and reducing power generation loss.
