Description

Triple Metal Filter {3 LAYER METAL FILTER}

The present invention relates to a triple metal filter for filtering food and beverages such as beer, wine, cooking oil, juice, etc. More specifically, a first metal mesh woven into fine metal fibers, and a second metal mesh woven into intermediate metal fibers And it relates to a triple metal filter composed of a third metal mesh woven plain metal coarse.

1 and 2, in the conventional food and beverage filter, the filter net 7 is wrapped in a cylindrical body 3 in which many holes 5 are regularly drilled.

However, the conventional food and beverage filter has a disadvantage in that the filter net is composed of one layer, which is burst by pressure during filtration, and the filter net is sewn with a polyethylene (or polypropylene) thread, or the filter net is spot welded. Since the debris is left, the filter net can burst, there is a disadvantage that you need to backwash at a low pressure of 3 ~ 9bar.

Accordingly, an object of the present invention is to join a first metal mesh woven into a thin wire metal fiber, a second metal net woven into a medium wire metal fiber, and a third metal net woven into a coarse wire metal fiber. It is suitable for filtering food and beverages requiring low density filtration of about 45% of the porosity, and the surface where the first metal network, the second metal network and the third metal network contact each other is melt-bonded in the sintering furnace, whereby It is to provide a triple metal filter that can maintain pores, and can guarantee a backwash rate of 95% or more.

The triple metal filter according to the present invention for achieving the above object is a first metal mesh woven into a metal fiber of fine wire diameter, a second metal mesh woven into a metal fiber of medium wire diameter, and a metal wire of coarse wire diameter It is composed of a third metal mesh woven into the plain, and the triple metal filter, characterized in that only the surface in which the first metal mesh, the second metal mesh and the third metal mesh contact each other in the sintering furnace melt-bonded,

The first metal mesh is made of stainless steel material, the wire diameter is 0.00099mm ~ 0.0232mm according to the filtration grade, and is woven into a standard sieve of 550mesh ~ 30mesh, substantially performing the function of filtering the filtrate Characterized in that.

The second metal mesh is made of stainless steel, and the wire diameter is 0.0049 mm to 0.23 mm depending on the filtration grade, and is woven into a standard sieve of 120 mesh to 16 mesh to disperse the pressure applied to the first metal mesh. It serves to protect the first metal mesh.

The third metal mesh is made of a stainless steel material, the wire diameter is 0.028mm ~ 0.7mm according to the filtration grade, and is a plain weave of standard mesh (25mesh ~ 8mesh), the first and second metal mesh It is characterized by acting as a pressure reinforcement to withstand the pressure applied by the filtrate.

In addition, the triple metal filter according to the present invention is formed in a cylindrical (or tapered cylindrical), the inner circumferential surface is disposed with the first metal mesh, the third metal mesh is disposed on the outer circumferential surface, the first metal mesh and the third metal A second metal net is disposed between the nets, a flange is welded at the top, and a stopper is welded at the bottom.

As a result, the triple metal filter according to the present invention can filter foreign matters while maintaining the natural taste and aroma of food and beverage, and can prevent foreign matters from occurring in the filter medium itself, and backwashing of 95% or more. The rate can be guaranteed, and any high pressure washing such as high temperature steam, ultrasonic wave, high pressure water (no deformation at 45 bar), the metal mesh is plain weave, and the mesh of the metal mesh is uniformly formed in a rectangular shape, so that the filtered filtration By having the particles averaged in water, the natural taste and aroma of the product can be maintained even after filtration, and only the surfaces where the first, second and third metal meshes are in contact with each other are melt-bonded in the sintering furnace, thereby The effect is that the network remains rectangular.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

3 and 4, the triple metal filter according to the present invention is the first metal mesh 10 is woven plain metal fiber, the second metal mesh 15 is woven plain medium metal fiber And a third metal mesh 20 that is plain woven with a coarse wire diameter metal fiber, and only the surface where the first metal mesh 10, the second metal mesh 15, and the third metal mesh 20 are in contact with each other. Melt-bonded in the sintering furnace.

The first metal mesh 10 is made of stainless steel, the wire diameter is 0.00099mm ~ 0.0232mm according to the filtration grade, and is woven into a standard sieve of 550mesh ~ 30mesh, substantially to filter the filtrate Perform the function.

The second metal mesh 15 is made of stainless steel material, the wire diameter is 0.0049mm ~ 0.23mm according to the filtration grade, and is woven into the standard sieve of 120mesh ~ 16mesh, applied to the first metal mesh The pressure is distributed to protect the first metal mesh.

The third metal mesh 20 is made of stainless steel material, the wire diameter is 0.028mm ~ 0.7mm according to the filtration grade, as a standard weave of 25mesh ~ 8mesh (Standard Sieve), the first metal mesh and the second The metal mesh serves as a pressure reinforcement to withstand the pressure exerted by the filtrate.

The characteristics of the first to third metal meshes according to the filtration grade of the triple metal filter according to the present invention are shown in Table 1.
