Detailed Description

The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the embodiments after studying the specification. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model provides a special strong aromatic white spirit filter sheet as shown in figures 1 and 2, which comprises a body 1, wherein the center of the body 1 is provided with an assembly port 2, a plurality of filtrate cavities 3 which are uniformly distributed are arranged inside the body 1, and the assembly port 2 is provided with a liquid outlet 4 communicated with the filtrate cavities 3; the body 1 is provided with a plurality of filter holes, and the aperture of each filter hole is 0.05-0.3 mu m; the assembly port 2 is provided with protruding portions 5 on both sides of the liquid outlet 4.

The outer contour of the body can be round, the surface is smooth and has no concave-convex feeling, a plurality of cavities are arranged in the body and are used as filtrate cavities for converging filtrate, and the filtrate cavities are uniformly distributed in the body, as shown in fig. 4; the body central authorities are provided with the assembly mouth, and the cassette is cup jointed through the assembly mouth and is gone out on the wine pipeline, and the shape of assembly mouth can be square or circular, and is unanimous with the shape of going out the wine pipeline, is convenient for seal. As shown in fig. 3, the filtrate chamber extends to the mounting port, and forms a liquid outlet on the side wall of the mounting port, and the filtrate can flow into the wine outlet pipe from the filtrate chamber through the liquid outlet and the small hole on the wine outlet pipe. The body, the filtrate cavity, the assembling port and the liquid outlet can be integrally formed by utilizing a mold, specifically, ultra-high molecular weight polyethylene is used as a raw material, and the molding and high-temperature sintering molding are carried out by utilizing the mold.

The body is a microporous filter plate, and has the characteristics of rich micropores, uniform pore diameter, large flux, high precision and the like, the micropores are the filter holes of the filter plate, and the size of the filter holes is 0.05-0.3 mu m aiming at flavor substances of the Luzhou-flavor liquor, so that a better filtering effect can be achieved. Experiments prove that the contents of acids and alcohols in flavor substances of the Maotai-flavor liquor are higher than those of various flavor liquors, and the flavor substances are mostly neutral or acidic components; the main flavor substances of the strong aroma type and the faint scent type are ethyl caproate and ethyl acetate respectively.

In one embodiment, when the filter hole is 0.1 μm, the content of the undesirable flavor components in the filtrate is obviously lost after the white spirit is filtered, such as isopropanol, 1-butanol, isoamylol and the like which are considered as fusel oil in the white spirit, and the concentration is reduced by 50%; the filtering effect of the higher fatty acid ethyl ester which is easy to cause wine turbidity in the filtrate is very obvious; the loss of medium-alkaline components such as alcohols and the like is large; the ethyl acetate is reduced from 97.21mg/L to 48.91mg/L, which is reduced by 49.7%; the reduction of ethyl caproate from 1295.18mg/L to 1293.77mg/L is very small; the ethyl butyrate endowing the strong aromatic Chinese spirits with old aroma is reduced from 117.27mg/L to 100.45mg/L, and the amplitude reduction is not obvious. In general, after filtration, the main flavor substances of ethyl hexanoate and ethyl butyrate which show strong aroma in the filtrate are more preserved, and the loss of main flavor substances of alcohols, ethyl acetate and the like of the Maotai-flavor type and the fen-flavor type is more, so that the strong aroma flavor is highlighted.

As shown in fig. 3, the assembling port is provided with protruding parts at two sides of the liquid outlet, so that an interference fit can be formed between the assembling port and the wine outlet pipeline, a primary seal is formed, and the sealing performance is improved; and secondly, the two protruding parts and the wine outlet pipeline enclose a channel, filtrate can circulate in the channel, and when a filter disc is installed in the wine outlet pipeline, the problem that the flow of the filtrate is adversely affected due to the fact that a liquid outlet cannot be over against a small hole in the wine outlet pipeline is avoided, and the installation fault tolerance rate is increased. The protruding part can be made of ultra-high molecular weight polyethylene and is integrally formed with the body.

Preferably, the number of said filtrate chambers 3 is between 6 and 10.

As shown in fig. 4, in order to maintain the strength and stability of the filter, the filtrate chamber must have a solid filter body around it as a support. The more the number of the filtrate cavities is, the larger the area proportion occupied by the filter plate entity is, the smaller the filtration flux is, and the adverse effect is generated on the filtration efficiency; the smaller the number of filtrate chambers, the less strength it is possible to maintain against the pressure of the liquor. The filter flux, the area ratio of the filter cavities and the strength of the filter sheet are comprehensively considered, and the number of the filter cavities can be 6-10. In one embodiment, the number of filtrate chambers is 8, which can achieve optimal filtration efficiency and strength.

Preferably, the thickness of the filtrate chamber 3 is 1/3-1/2 of the thickness of the body 1.

As shown in fig. 5, the filtrate cavity is centered, and in the case of limited thickness H of the filter plate body, the thickness H1 of the filtrate cavity is in negative correlation with the thickness H2 of the filter plates on both sides of the filtrate cavity, while the thickness H2 of the filter plates on both sides of the filtrate cavity is in positive correlation with the filtering effect, and the thickness H1 of the filtrate cavity is in positive correlation with the filtering flux. The larger the thickness H1 of the filtrate cavity is, the smaller the thickness H2 of the filter sheets at two sides is, and the poorer the filtering effect is. When the thickness H1 of the filtrate chamber is 1/3-1/2 of the body thickness H, a balance between filtration efficiency and filtration flux can be achieved.

Preferably, the fitting opening 2 is square or circular.

The shape of the assembly opening is consistent with that of the wine outlet pipeline, so that the sealing performance is improved, and the regular shape, such as square or round shape, is better.

The above is an embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
