[0002] During the brewing process, filtration is a key step in ensuring the quality of the liquor and improving its taste. During fermentation, distillation and storage, impurities such as lees particles, proteins, higher fatty acids and ethyl esters are often mixed in, which not only affect the clarity of the liquor, but may also cause turbidity, sedimentation and even affect the taste and flavor.

[0003] Existing raw liquor filtration devices, such as CN203329455U, disclose a novel liquid filtration device for white spirits, including a cylinder, filter elements, an inlet, an outlet, and a cap. Several filter elements are arranged inside the cylinder, and a fixing plate is provided at the upper and lower ends of the cylinder. The fixing plate has several fixing holes, and a filter element shaft is movably installed within the fixing holes. The filter element shaft is spirally inserted, and a filter element is fitted onto the filter element shaft. A central tie rod is provided between the fixing plate and the cap at the upper end of the cylinder. This invention solves the problem of the central fixing shaft of traditional liquid filtration devices rusting and falling off after prolonged immersion in liquor. The movable filter elements facilitate installation and maintenance, and the various opening and closing methods of the cap and cylinder can be freely selected by the producer according to production needs. In the prior art, filtration devices only perform single-pass filtration of the liquor, resulting in poor filtration efficiency.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-2 As shown, a raw wine filtration device includes: a shell 1, a coarse filter layer 2, a fine filter layer 3, a molecular sieve filter layer 4, and support legs 5; the shell 1 is provided with the coarse filter layer 2, the fine filter layer 3, and the molecular sieve filter layer 4; the coarse filter layer 2 is located above the fine filter layer 3, and the fine filter layer 3 is located above the molecular sieve filter layer 4; both the coarse filter layer 2 and the fine filter layer 3 have a V-shaped structure with the pointed ends facing upwards; the bottom surface of the shell 1 is fixedly connected to multiple support legs 5; the bottom surface of the shell 1 has a liquid outlet and is detachably connected to a liquid outlet pipe 6; the top surface of the shell 1 has a liquid inlet and is detachably connected to a liquid inlet pipe 7.

[0034] In this invention, the coarse filter layer 2 is a food-grade stainless steel filter screen, and the fine filter layer 3 is a diatomaceous earth filter layer; the top plate, side plate, and bottom plate of the shell 1 all have a certain thickness, which is based on the technical solution of this application; there is a certain distance between the coarse filter layer 2, the fine filter layer 3, and the molecular sieve filter layer 4; the liquid outlet and liquid inlet are provided with internal threads, and the liquid outlet pipe 6 and the liquid inlet pipe 7 are respectively provided with external threads that match the internal threads, so as to achieve detachable connection; the wine is filtered three times by setting the coarse filter layer 2, the fine filter layer 3, and the molecular sieve filter layer 4. First, the coarse filter layer 2 filters out the residual solid particles in the wine; second, the fine filter layer 3 removes fine particles, some colloids, and off-flavor substances; finally, the molecular sieve filter layer 4 filters out molecular-level impurities and flavor substances; the V-shaped structure of the coarse filter layer 2 and the fine filter layer 3 increases the effective filtration area, guides particles to slide to both sides to reduce clogging on the surface of the filter material, and at the same time makes the wine evenly distributed to avoid local filtration overload.

[0035] In this invention, the molecular sieve filter layer 4 typically requires appropriate pressurization during filtration, but the pressure must be strictly controlled, generally between 0.1-0.5 MPa, and adjusted according to the viscosity of the wine and the filtration precision. The purpose of this operation is to overcome filtration resistance and ensure filtration efficiency, while avoiding excessive pressure that could damage the flavor of the wine or the molecular sieve structure. Pressurizing the molecular sieve filter layer is also one of the core conditions for continuous production. Continuous production requires uninterrupted wine filtration and stable flow. However, without proper pressurization, the high precision of molecular sieve filtration can lead to production interruptions due to high resistance and unstable flow rate. Therefore, pressurization is applied to the molecular sieve filter layer to meet the requirements of continuous production.

The inlet continuously flushes the first coarse filter layer 2 with wine, and the particulate matter flows into the collection box 9, achieving centralized collection.
