Description
Technical Field
The invention relates to the technical field of soy sauce processing, in particular to a system for recovering soy sauce from soy sauce feet.
Background
The soy sauce is a traditional Chinese seasoning and is mainly brewed from soybeans, wheat, salt and the like. Chinese people have mastered the brewing process of soy sauce several thousand years ago, the soy sauce contains various amino acids, saccharides, organic acids, pigments, spices and other ingredients, and the soy sauce can add and improve the taste of food and change the color of dishes, so that the soy sauce becomes an important seasoning indispensable in the life of people.
The brewing technology of soy sauce has become more and more mature after thousands of years of development. However, the problem of soy sauce foot treatment is common in soy sauce brewing production. The finished soy sauce or semi-finished soy sauce is characterized in that a part of soy sauce residue is always accumulated at the bottom of an underground pool and the bottom of a finished soy sauce tank stored in a large tank, is a precipitate part of a supernatant removed after the finished soy sauce or the semi-finished soy sauce is settled, and mainly comprises fine organic particles, insoluble protein, salt mud and other impurities and part of soy sauce mixed. When the soy sauce residue is accumulated to a certain degree at the bottom of the pool or the bottom of the jar, the soy sauce residue must be cleaned to remove the soy sauce residue or the soy sauce residue is clarified to cause soy sauce turbidity. The soy sauce foot accounts for about 10 percent of the total soy sauce, the variety is complicated, the acidity is high, protease generated in the starter propagation process is difficult to utilize, and the soy sauce can not be recycled and fermented. So how to recover the soy sauce in the soy sauce foot is a key problem.
In the prior art, three treatment modes of direct filter pressing, treatment by adding diatomite into soy sauce foot and treatment by adding specific enzyme after pumping out the soy sauce foot to carry out enzymolysis on the soy sauce foot are generally adopted.
Direct filter pressing is generally direct filter pressing by adopting a diaphragm filter press, but as the soy sauce residue is a product after soy sauce sedimentation, the soy sauce residue contains fine organic particles, insoluble protein and other impurities, feed liquid is viscous and easy to block filter cloth, so that the filtering efficiency is very low, and more soy sauce impurities directly filtered out by pressure need to be filtered by a process after subsequent recovery.
The diatomite is added into the circulating tank in a certain proportion and stirred uniformly, pre-filtering is carried out firstly, the diatomite is spread on the filter cloth of the filter press to form a filter layer, and then the filter press is carried out. Although the filtering speed is improved after the diatomite is added, the protein precipitate still blocks a filtering layer formed by the diatomite, the filtering efficiency is still not high, and the filter residue contains the diatomite and cannot be reused or directly discharged.
And specific enzyme is added into the soy sauce foot to carry out enzymolysis on the protein in the soy sauce foot and then carry out filter pressing, so that the filtering speed can be improved, and the environment pollution can not be caused by the discharge of filter residue. However, the time for adding enzyme to carry out enzymolysis on the protein in the soy sauce foot is long, the subsequent treatment process is complicated, and the required investment is larger.
It can be seen that the treatment processes of the prior art are still to be improved.

a raw material storage device for storing a raw material liquid; the raw material liquid is soy sauce residue;
a centrifugal filtration device which is in fluid communication with the raw material storage device and establishes a circulation flow path for centrifugal cross-flow filtration of soy sauce feet in the introduced raw material liquid;
the filtrate buffer device is in fluid communication with the centrifugal filter device and is used for buffering filtrate formed after the filtrate is filtered by the centrifugal filter device;
the first power device is used for providing conveying power for the raw material liquid in the circulating flow path; and
and the second power device is used for providing rotary power for the centrifugal filtering device.
2. A system for recovering soy sauce from soy sauce feet as set forth in claim 1, wherein said centrifugal filter means comprises:
the shell is provided with a stock solution inlet, a trapped solution outlet and a filtrate outlet, and the stock solution inlet and the trapped solution outlet are both in fluid communication with the raw material storage device so as to establish the circulating flow path with the raw material storage device;
the rotating shaft is of a hollow structure, the interior of the rotating shaft is communicated with the filtrate outlet, and the rotating shaft is arranged in the shell and is in rotating connection with the shell; and
the centrifugal membrane element is arranged in the rotating shaft to rotate along with the rotating shaft relative to the shell, and is used for carrying out centrifugal cross-flow filtration on the soy sauce feet in the raw material liquid and enabling the filtrate to flow out of the centrifugal filter device through the filtrate outlet.
3. A system for recovering soy sauce from soy sauce feet as set forth in claim 2, wherein: the separation pore size of the centrifugal membrane element is in the range of 5nm-2 μm.
4. A system for recovering soy sauce from soy sauce feet as set forth in claim 2, wherein: the rotating shaft is provided with a plurality of turbulence discs along the radial direction.
5. A system for recovering soy sauce from soy sauce feet as set forth in claim 2, wherein: the second power device is a centrifugal motor and is in rotation stopping connection with the rotating shaft so as to drive the rotating shaft to rotate relative to the shell.
6. A system for recovering soy sauce from soy sauce feet as set forth in claim 2, wherein: the first power device is a circulating pump;
the system further comprises:
a gas source in fluid communication with the circulation pump for providing gas power to the circulation pump; and
and the circulating pump air supply valve is arranged between the air source and the circulating pump and used for controlling the on-off of fluid between the air source and the circulating pump.
7. The system for recovering soy sauce from soy sauce feet as set forth in claim 6, wherein: a pressure gauge and a return valve are also arranged on the circulating flow path;
the pressure gauge is used for detecting the liquid pressure of the circulating flow path; the backflow valve is used for controlling the on-off of the fluid in the circulating flow path.
8. The system for recovering soy sauce from soy sauce feet as recited in claim 6, further comprising:
and the backflushing valve is arranged between the gas source and the filtrate buffer device and is used for leading gas to the centrifugal filter device reversely through the filtrate buffer device when the backflushing valve is opened so as to backflush a centrifugal membrane element of the centrifugal filter device.
9. A system for recovering soy sauce from soy sauce feet as claimed in any one of claims 1 to 8, further comprising:
and the filtrate discharge valve is communicated with the filtrate buffer device in a flowing mode and is used for controlling the discharge of the filtrate and recovering the filtrate.
10. A system for recovering soy sauce from soy sauce feet as claimed in any one of claims 1 to 8, wherein: the raw material storage device and the filtrate buffer device are both liquid storage tanks;
the circulation flow path, the centrifugal filter device and the filtrate buffer device are all in fluid communication through pipelines.
