[0011]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the method for producing soymilk according to claims 1 and 2 , wherein reference numeral 41 denotes a grinder that pulverizes soybeans immersed in water for a predetermined time in an immersion tank to make a soybean. ing.

When the soybean is crushed by the grinder 41, a predetermined amount of water is supplied from the water supply pipe 43. The goss crushed by the grinder 41 is, for example, at a temperature of 20 ° C., and is passed through a bent pipe 47 provided in a container 45 of the extraction device 44, for example, for 2 minutes.
The protein extraction effect is improved.

The go which has passed through the pipe line 47 is supplied to a first heating device 49, where it is heated, for example, for 2 minutes and then heated to 70 ° C. The first heating device 49 includes a heat exchanger 51, a pump 55 that supplies a high-temperature fluid composed of, for example, 75 ° C. hot water to a shell 53 of the heat exchanger 51, and a tank that stores hot water at 75 ° C. 57.

A hot water inlet is formed on one side of the shell 53, and a hot water outlet is formed on the other side. In the shell 53, a go flow conduit 69 is formed.
Tubes 71 are inserted through these tubes 71
Are connected so as to communicate in series.

One of the 19 tubes 7
1 has a go-go inlet, and one tube 71 has a go-go outlet. That is, in the first heating device 49, gochi is continuously circulated from the go inlet to the go outlet of the go flow channel 69 formed in the shell 53, while, towards from the hot water inlet <br/> shell to the hot water outlet, hot water continuously circulate, rubber is heated and the hot and rubber by heat exchange.

By the first heating device 49, for example, 70
The goose heated to 0 ° C. is passed, for example, for 2 minutes through a bent pipe 83 provided in a container 81, thereby improving the protein extraction effect and adjusting the heat denaturation of the protein. Is done. After that, the metal heated to 70 ° C. is supplied to the second heating device 85 and heated to 90 ° C.

The second heating device 85 is substantially the same as the first heating device 49 except that the temperature of the hot water is set to 95 ° C., for example. The same reference numerals are given and the detailed description is omitted. Thereafter, the goose heated to 90 ° C. is supplied into a cooking pot of a thermoforming device 87, and stewed (beans) by direct heating with steam.
For example, the mixture is heated for 5 minutes while visually observing the state of boiling (which is regarded as boiling in the rot manufacturing industry) .

After completion of the heating, the gogo is squeezed in a squeezing machine unit to remove okara and to produce soymilk. Thus, in the method for producing soymilk described above , the pipe 4
7, an extraction step of extracting proteins by circulating goss, and after this extraction step, a go circulating line 6 of the heat exchanger 51.
9 and a heating step in which heat is exchanged with hot water by flowing the go, and a heating step in which the heated go is heat-formed by direct heating with steam after this heating step. Without mixing the steam drain, the go can be boiled without fail, and the protein can be extracted well.

That is, in the method for producing soymilk of this embodiment, the goose is gradually heated in three steps: an extraction step, a heating step by heat exchange with hot water, and a thermoforming step. This prevents the high temperature from directly acting on the goose, resulting in gelation of the goat, poor extraction of protein, loss of protein elasticity, and poor shelf life of tofu. It can be eliminated.

In the above-described method for producing soymilk, goji is continuously circulated in the gogo distribution line 69, and the gogo is indirectly heated by the hot water continuously flowing in the shell 53. Steam is no longer mixed with the goose, so that when soybeans are crushed by the grinder unit 41, it is possible to increase the amount of water that was previously mixed with steam drain, thereby reducing heat denaturation of proteins. In addition, it is possible to improve the extraction of proteins.

As a result, the yield of the produced tofu can be improved by about 10% as compared with the conventional one. In addition, since the goji is heated while circulating the gogo in the gogo distribution line 69, the first-in and first-out operations are completed, and it is possible to perform a reliable boiling without unevenness, and the separation of okara from the goat is improved. And
Also, the separated okara becomes very white.

Furthermore, in this embodiment, the first heating device 49 and the second heating device 85 heat the gogo in two stages, so that no scorching occurs and the soy milk becomes very homogeneous. . In this embodiment, the thermoforming device 8
In the cooking pot of No. 7, by direct heating by steam,
Since the go is heat-produced, the stew of the go is completed, and the color, gloss, elasticity, etc. of the produced tofu are improved.

Then, in the boiling apparatus of this embodiment, an extraction device 44 having a pipeline 47 through which the goose is circulated, a heat exchanger 51 for exchanging heat between the gore and hot water, and a heat exchanger for directly heating the gore by steam. Since it is composed of the synthesizing device 87, the method for producing soymilk of this embodiment can be simply, reliably and easily performed. In the embodiment described above, the first
Although the example in which the heating device 49 and the second heating device 85 heat the gob in two stages has been described, the present invention is not limited to such an embodiment, and the single-stage heating using only one heating device is performed. But of course it is good.

In the above-described embodiment, the bent pipe 8 is provided between the first heating device 49 and the second heating device 85.
Although the example in which 3 is arranged has been described, the present invention is not limited to such an example, and it is needless to say that the bent pipe 83 is not necessarily required.
