Problems solved by technology

The traditional long cleaning process has many processes, the total cleaning time is long, and the cleaning consumption is large, which invisibly increases the operating cost of the brewery and reduces the utilization rate of the equipment.
But for the optimization of the cleaning process of the ceramic membrane used for beer filtration, to further reduce the cleaning time, there are few studies and reports in the current prior art

Embodiment 3

[0050] In embodiment 3, in addition to the device that embodiment 1 and embodiment 2 possess, flow meter 11 is installed between temperature measuring device 10 and ceramic membrane assembly 7 again, for measuring the flow rate when clear water passes ceramic membrane rod 8, and then The flow rate of clear water is controlled by the cleaning pump 6 . Depending on the cross-sectional area of ​​the ceramic membrane rod 8, the selected cleaning flow rate is also different, and the specific flow rate can be calculated according to "cross-sectional area * flow rate * time". In this embodiment, the flow rate is further controlled at 2-3m / s. Too low a flow rate is not conducive to washing impurities in the ceramic membrane rod 8 with clean water. Too high a flow rate will have a greater impact on the device and generate greater noise. In this embodiment, the preferred clear water flow rate is 2.5m / s.

[0051] In addition, when the ceramic membrane itself has some impurities that are...

Abstract

The invention provides a cleaning method for a beer filtration ceramic membrane. The cleaning method comprises: (1) pre-rinsing a ceramic membrane by using clear water; (2) adding a cleaning agent, and completely immersing the ceramic membrane in the cleaning agent, wherein the cleaning agent is a mixed solution of sodium hydroxide and sodium hypochlorite; and (3) rinsing the ceramic membrane by using clear water until the aqueous solution after the rinsing is substantially neutral. The invention further provides a cleaning apparatus for a beer filtration ceramic membrane, wherein the cleaningapparatus is connected to the inlet and the outlet of a ceramic membrane assembly through pipelines, a clear water tank and a cleaning agent tank are connected to the inlet of the ceramic membrane assembly through a cleaning pump, and the cleaning pump can pump clear water or a cleaning agent into a ceramic membrane, and rinse and soak the ceramic membrane. With the cleaning method of the presentinvention, the ceramic membrane cleaning time is shortened so as to improve the production efficiency of beer and reduce the production cost. The cleaning apparatus of the present invention is easy to operate, and can save a lot of time for the whole cleaning process.

Description

technical field [0001] The invention relates to a ceramic membrane cleaning method, in particular to a cleaning method and a cleaning device for a ceramic membrane used to filter beer. Background technique [0002] With the innovation of science and technology, in the field of beer filtration, the current traditional diatomite beer filtration technology is gradually being eliminated. In order to achieve higher beer filtration efficiency and ensure good beer quality, while meeting the technical concept of environmental protection, it is replaced by An advanced membrane filtration technology. At present, the filter membrane can be divided into two types according to the material. One is a mesoporous fiber filter membrane made of polyethersulfone. The material of the membrane is sensitive to temperature, pressure, and cleaning agent, and its service life is relatively short. It needs to be maintained and replaced within 3 years, the frequency of replacement is high, and the co...
