Description
Technical Field
The utility model belongs to the technical field of oyster juice concentration and extraction, and particularly relates to an oyster juice concentration and extraction system.
Background
Oyster sauce is a seasoning prepared by boiling oyster (oyster) and is one of the most popular products of seasoning juice, and is prepared by boiling oyster as a raw material, taking oyster juice for concentration and adding auxiliary materials. In the existing process of stewing and boiling oyster juice, a large amount of fuel gas is used, and the energy consumption is high. Meanwhile, the oyster serving as a marine product has high salt content, so that the salt content is continuously concentrated in the cooking process, which easily causes the salt content to be too high, and influences the quality of the final oyster sauce.
Disclosure of Invention
The utility model aims to provide an oyster juice concentrating and extracting system, which can reduce the salt content of concentrated oyster juice and improve the quality and taste of the oyster juice.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the oyster juice concentrating and extracting system provided by the utility model comprises a sedimentation tank, a ceramic membrane, a nanofiltration membrane and a cooking device, wherein a supernatant outlet of the sedimentation tank is communicated with a liquid inlet of the ceramic membrane, a dialysate outlet of the ceramic membrane is communicated with a liquid inlet of the nanofiltration membrane, and a concentrated solution of the ceramic membrane and the nanofiltration membrane are mixed and then communicated with a liquid inlet of the cooking device.
Preferably, the ceramic membrane is a tubular ceramic membrane.
Preferably, the filtration mode of the ceramic membrane is cross-flow filtration.
Preferably, the pore size of the ceramic membrane is 30-200 nm.
Preferably, the sodium chloride permeability of the nanofiltration membrane is 80-95%.
Preferably, the operating pressure of the nanofiltration membrane is between 10 and 25 bar.
Preferably, the cooking device is a multiple effect evaporator.
The utility model has the beneficial effects that:
1. the salt content of the concentrated oyster juice is reduced by 50-80%, and the quality and taste of the oyster juice are improved.
2. The energy consumption of the whole oyster juice concentration process is reduced by 60-80%.
Drawings
FIG. 1 is a system block diagram of the present invention.
The labels in the figures are: 1-a sedimentation tank, 2-a ceramic membrane, 3-a nanofiltration membrane and 4-cooking equipment.
Detailed Description
The utility model will now be further described with reference to the accompanying drawings and detailed description.
Those not described in detail in this specification are within the skill of the art. In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the oyster juice concentrating and extracting system provided in this embodiment includes a sedimentation tank 1, a ceramic membrane 2, a nanofiltration membrane 3, and a cooking device 4, wherein a supernatant outlet of the sedimentation tank 1 is communicated with a liquid inlet of the ceramic membrane 2, a dialysate outlet of the ceramic membrane 2 is communicated with a liquid inlet of the nanofiltration membrane 3, a concentrated solution of the ceramic membrane 2 and the nanofiltration membrane 3 is mixed and then communicated with a liquid inlet of the cooking device 4, wherein the concentrated solution can be directly fed into the cooking device 4 through pipeline mixing, or can be concentrated in a mixing tank and then fed into the cooking device 4.
The boiled primary oyster juice is primarily precipitated in the sedimentation tank 1 to remove oyster shells, silt and residues, and then the precipitated supernatant enters the tubular ceramic membrane 2 to be subjected to cross flow filtration, so that primary concentration and dehydration are performed, and the dehydration cost is reduced. The aperture of the ceramic membrane 2 is 30-200nm, the flow speed is 2.5-6m/S, the pressure is 1.5-6bar, after 2-6 times of concentration, the dialysate is passed through the nanofiltration membrane 3 to carry out dehydration and desalination, and beneficial substances such as amino acid, taurine, zinc and the like leaked in the dialysate of the ceramic membrane 2 are recovered, the concentration is 5-10 times, the sodium chloride transmittance of the nanofiltration membrane 3 is 80-95%, and the operating pressure is 10-25 bar. And mixing the concentrated solution of the nanofiltration membrane 3 and the concentrated solution of the ceramic membrane 2, and performing primary cooking concentration. Obtaining the final concentrated oyster juice.
Further, the cooking device 4 is a multi-effect evaporator. And the multi-effect evaporator is adopted for concentration, so that the energy consumption is saved compared with gas steam.
The utility model reduces the energy consumption of the whole oyster juice concentration process by 60-80%. The salt content of the concentrated oyster juice is reduced by 50-80%, and the quality and taste of the oyster juice are improved.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
