Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to a flour sieve which is convenient for stacking. Background Art
[0002] Flour is a powder made from wheat. Flour is very easy to get damp and clump during storage. Such flour will form many small lumps when making pasta, affecting people's taste. Flour sifter is a necessary tool in the kitchen. It can remove some small lumps in the flour, making the flour finer, making the pasta more fluffy and tastier. However, flour sifters are usually cylindrical sieves. When stacked, they will occupy a large stacking space during transportation, increasing transportation costs. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a flour sieve that is easy to stack. The flour sieve can be stored in an up-and-down stacking manner, which can save stacking space during transportation, thereby reducing transportation costs. The technical solution adopted is as follows:
[0004] A flour sieve that is easy to stack, includes a sieve drum and a sieve mesh, wherein the upper end and the lower end of the sieve drum are respectively provided with an upper opening and a lower opening, and the characteristic is that: the sieve drum has an inner cavity whose cross-sectional area gradually decreases from its upper opening to its lower opening; an inner flange extending horizontally inward is provided at the lower opening of the sieve drum, an annular support bar is provided at the lower end of the sieve drum, the annular support bar is located at the lower side of the inner flange and forms an annular positioning groove with the inner flange, and the outer peripheral portion of the sieve mesh is installed in the annular positioning groove.
[0005] In the structure of the flour sieve, an annular positioning groove can be formed at the lower opening of the sieve cylinder by the inner flange and the annular support strip arranged at the lower end of the sieve cylinder, which is used to clamp and position the outer peripheral part of the sieve, thereby making the overall structure of the flour sieve more compact and stable. When stacking multiple flour sieves, since the sieve cylinder has an inner cavity whose cross-sectional area gradually decreases from its upper opening to its lower opening, the lower part of the sieve cylinder of the upper flour sieve can be placed from the upper opening of the next flour sieve into the inner cavity of the sieve cylinder of the next flour sieve, and so on, so that multiple flour sieves can be combined and stored by stacking them up and down, and the overall height of the multiple flour sieves after stacking can be greatly reduced, which can save stacking space during transportation, thereby reducing transportation costs.
[0006] Usually, the shape and size of the inner cavity of the sieve cylinder match the outer wall of the sieve cylinder. When the lower part of the sieve cylinder of the upper flour sieve is placed into the inner cavity of the sieve cylinder of the lower flour sieve from the upper opening of the lower flour sieve, the outer wall of the lower part of the sieve cylinder of the upper flour sieve contacts and cooperates with the inner wall of the sieve cylinder of the lower flour sieve.
[0007] As a preferred solution of the utility model, the upper opening of the sieve cylinder is provided with an outer curling edge folded outwards, which can be held by a user to facilitate operations such as moving and vibrating the flour sieve.
[0008] The cross section of the inner cavity of the screen drum can be circular, elliptical or regular polygonal.
[0009] As a preferred solution of the utility model, the side wall of the sieve drum is in a truncated cone shape, the upper opening and the lower opening of the sieve drum are both circular, and the diameter of the upper opening is greater than the diameter of the lower opening.
[0010] As a further preferred embodiment of the present invention, the side wall taper of the sieve drum is 8°-16°, thereby ensuring that multiple flour sieves can be stored in a stacked manner without reducing the sieve area as much as possible, further ensuring the flour sieving capacity of the flour sieve.
[0011] As a further preferred solution of the utility model, the side wall of the screen cylinder is welded by inverted trapezoidal stainless steel sheets. The annular support bar can also be made of stainless steel.
[0012] As another preferred embodiment of the present invention, the side wall of the sieve cylinder is in the shape of a square pyramid with a larger upper portion and a smaller lower portion, and the upper opening and the lower opening of the sieve cylinder are both in the shape of a square.
[0013] As a further preferred embodiment of the present invention, the side wall taper of the sieve drum is 8°-16°, thereby ensuring that multiple flour sieves can be stored in a stacked manner without reducing the sieve area as much as possible, further ensuring the flour sieving capacity of the flour sieve.
[0014] Compared with the prior art, the utility model has the following advantages:
[0015] This flour sieve is not only compact and stable in structure, but also can be stored in combination by stacking up and down, which can greatly reduce the overall height of multiple flour sieves after stacking and storage, save stacking space during transportation, and thus reduce transportation costs.

[0020] like Figure 1-Figure 4 As shown, the flour sieve 10 which is easy to stack comprises a sieve drum 1 and a sieve mesh 2. The upper end and the lower end of the sieve drum 1 are respectively provided with an upper opening 101 and a lower opening 102. The sieve drum 1 has an inner cavity 100 whose cross-sectional area gradually decreases from its upper opening 101 to its lower opening 102. An outer rolled edge 11 folded outward is provided at the upper opening 101 of the sieve drum 1, and an inner flange 12 extending inward horizontally is provided at the lower opening 102 of the sieve drum 1. An annular support strip 13 is provided at the lower end of the sieve drum 1. The annular support strip 13 is located at the lower side of the inner flange 12 and forms an annular positioning groove 103 with the inner flange 12. The outer peripheral portion of the sieve mesh 2 is installed in the annular positioning groove 103.
[0021] In this embodiment, the side wall of the screen drum 1 is in the shape of a truncated cone with a taper of 12°, and the side wall of the screen drum 1 is welded from inverted trapezoidal stainless steel sheets; the upper opening 101 and the lower opening 102 of the screen drum 1 are both circular, and the diameter of the upper opening 101 is larger than the diameter of the lower opening 102. In this way, it is possible to ensure that multiple flour sieves 10 can be stored in a stacked manner without reducing the area of the screen 2 as much as possible, thereby further ensuring the flour sieving capacity of the flour sieve 10.
