A separated sieve of a flat round sieve for Oolong tea, the flat round sieve and a working method

Abstract

The invention relates to a separated sieve of a flat round sieve for Oolong tea, the flat round sieve and a working method. The separated sieve is characterized in that the separated sieve is a screenmanufactured by punching round holes in a stainless steel plate, the mesh number of the screen is 1.5 meshes, and a triangle is formed by connecting center points of each three adjacent round holes with lines. The separated sieve which is a first screen is the screen manufactured by punching the round holes in the stainless steel plate, has high bearing capacity, and is stable in structure and high in strength when compared with traditional screens having staggered square steel wire meshes, and therefore the separated sieve is not liable to damage or sink during tea screening and the servicelifetime is greatly prolonged. In addition, stainless steel screens manufactured by forming the round holes avoid a tea clamping phenomenon, and therefore the number of times of cleaning clamped tea leaves everyday is greatly reduced during tea screening, and the production and tea screening efficiency is increased.

Description

Technical field: [0001] The invention relates to a flat-round sieving sieve for oolong tea, a flat-round sieve and a working method. Background technique: [0002] Oolong tea originated in Fujian and has a history of more than 1,000 years. The formation and development of Oolong tea must first be traced back to Beiyuan tea. Beiyuan tea is the earliest tribute tea in Fujian, and it is also the most famous tea after the Song Dynasty. There are more than ten books introducing the production and brewing of Beiyuan tea in history. As a special famous tea in my country, oolong tea has been confirmed by modern scientific research at home and abroad. In addition to general tea, oolong tea has refreshing benefits, eliminates fatigue, promotes body fluid and diuresis, relieves heat and heatstroke, sterilizes and prevents inflammation, detoxifies and prevents diseases, eliminates food and greasy, loses weight and maintains health care. In addition to functions, it also has special e...

Problems solved by technology

[0003] At present, oolong tea is also liked by more and more people, but since oolong tea needs to be brewed with hot water when brewing, it is impossible to drink tea anytime and anywhere. Therefore, oolong tea beverages have appeared. The production efficiency is low, especially when the color sorter is used, there are 7 to 15 sieved teas after the raw tea is refined, and then blended, the production efficiency is particularly low

[0004] At present, the sieves of each layer of the traditional tea sieve are grid sieves, that is, the criss-cross screen of barbed wire. Because it is a sieve formed of criss-cross barbed wire, its support effect is poor, and it is easy to sink when the tea is screened. and damage, and it is easy to pick up tea, causing it to be shut down and cleaned more than 5-6 times a day during use
