Drying screen

Abstract

The invention belongs to the field of tea production tools and in particular relates to a drying screen for drying tea. The drying screen comprises at least two layers of screen cloths, wherein the layer surfaces of the screen clothes coincide; each screen cloth is correspondingly provided with a closed-ring-shaped frame used for supporting and setting the screen cloth; each screen cloth is matched with the corresponding frame to form a drying screen unit; the surfaces of the screen cloths have a separate or fit position state; the screen clothes are fixed on the frame surfaces on the same side of the frames and correspondingly form screen bottoms; the drying screen units also comprise press strips arranged at the screen bottoms and used for fixing the screen cloths; a dent is arranged in the middle section of the body of each frame; the dent extends along the closed ring direction of each side of the frame and forms a closed-ring-shaped groove; and the press strips correspondingly have closed-ring-shaped appearances and form embedded fixed connection matching with the grooves. The drying screen has the following beneficial effects: the product production precision is high; the tension property of the whole screen cloth is effectively ensured; if the screen is matched with the iron frame, good service life of the screen can be further ensured; and finally the quality of the finished tea product can be greatly improved.

Description

technical field [0001] The invention belongs to the field of tea making tools, and in particular relates to a drying sieve for drying tea. Background technique [0002] Drying is an important process in tea making. Its main purpose is to remove all the water in and out of the tea, and at the same time achieve the purpose of tea shaping and oxidation resistance. Drying sieve is widely used in tea drying process. The drying sieve usually uses two sieve bodies, one large and one small, as a pair. The flattened tea leaves are directly spread on the outer sieve body, and then the inner sieve body is pressed on the outer sieve body, so as to use the same surface of the large and small sieve bodies. The steel wire screen is superimposed to clamp the flattened tea leaves to ensure that the tea leaves are flat and straight after drying; because the screen is densely covered with holes, the tea moisture can be distributed through the above holes, and the moisture inside and outside t...

AI Technical Summary

Problems solved by technology

Most of the existing drying sieves are made of wood or iron, and have the following defects: First, due to the influence of tea moisture and drying temperature, the working environment of the drying sieve often has both moisture and high temperature, and the wooden frame of the drying sieve is affected by moisture and drying temperature. Wood loosening or even deformation is very easy to occur in high temperature environment. Since the main function of the drying sieve is to clamp the leaves to keep the flat shape when the tea is drying, once the frame used for shaping the sieve is deformed, it will inevitably cause the drying sieve to lose its shape. The clamping effect of the surface is sharply reduced or disappeared, which not only affects the quality of tea, but also greatly limits the service life of the wooden frame; secondly, the existing wooden or iron baking sieve is used to fix the wire mesh on its frame The screws of the sieve will more or less loosen with the increase of the number of uses, so that it is impossible to ensure that the sieve is always in a tight state, resulting in most of the tea leaves being curled and deformed after drying, and the quality of the tea is greatly reduced; Because of the material, the service life is extremely short, resulting in frequent replacement and high cost investment, which is difficult to meet the manufacturer's economic profit needs
