Description

Preparation process and automatic production line for brewing raw tea in bottled cold water

Technical Field

The invention belongs to the technical field of disposable drinking water, and particularly relates to a preparation process and an automatic production line for brewing original tea in bottled cold water.

Background

The cold-brewing tea is to directly brew tea leaves with cold water, so that the beneficial components in the tea leaves are slowly dissolved and released, and the cold-brewing tea can be drunk without refrigeration after being soaked for a long time and poured out, and the release of theophylline in the tea leaves can be reduced, so that the bitter taste of the tea water can be reduced, and the cold-brewing tea is also called as cold-water tea. Most of the existing cold-brewing tea can not be stored for a long time and can not be developed and sold on the market like other beverages; in addition, the existing cold-brewing tea is soaked in cold water at room temperature or low temperature in a natural state, so that the soaking time is long, and the cold-brewing tea is not suitable for industrial production. If the existing mineral water bottle is used for making cold tea, tea leaves can inevitably enter water and are inconvenient to drink.

The inventor has invented a patent in 2015104602512 filed on 31/7/2015, a method for storing instant mixed beverage in a grid storage in a same container and a device thereof. The disposable beverage of the invention is separated from tea water during production, and the tea water and the tea leaves can be fused into the ready-to-drink cold and clear beverage by simple action during use, and the tea leaves are separated from the tea water, thus achieving the purpose of prolonging the shelf life of the beverage compared with the shelf life of the common beverage.

The inventor applies for a patent 2016211146590 'disposable cold tea packaging bottle' in 2016 (10/12), which solves the problem of instant drinking of disposable cold tea, and the bottom of the tea container can be opened only by pressing the pressing cover into the tea container with hands.

The inventor also discloses a simple disposable cold-brewing tea packaging bottle in a patent 201621209108, which is applied in 2016, 11, 9 and improves the structure, so that a more effective and convenient device is invented, the simple disposable cold-brewing tea packaging bottle is suitable for drinking after being brewed at one time, a supporting cover needs to be supported in a tea container, water and tea are fully fused and soaked, then the bottle cover is unscrewed, and the tea can be drunk through a water outlet of the supporting cover. On the basis, the inventor invents a more convenient cold water tea feeding and bottle opening integrated device, can quickly brew cold tea at the present time by pushing a cap opener, can directly open the cap for one-time use, achieves the aim of tea feeding and bottle opening integration, and applies for a cold water tea feeding and bottle opening integrated device on 12 th 10 th 2018 (201825349).

Meanwhile, the conventional bottled cold water brewing raw tea is produced manually or mechanically in a semi-automatic manner, the production efficiency is low, the social and economic benefits are not high, and the production process flow of the bottled cold water brewing raw tea of the company in which the applicant is located is as follows: bottle feeding and conveying → empty bottle washing → beverage filling → inner cap press fitting → cap screwing and mounting. Therefore, in order to realize full automation of the production process, reduce the labor intensity of workers, improve the social and economic benefits, add a new variety to the beverage market and solve the market demand of cold water tea in daily life of people, the preparation process and the automatic production line of bottled cold water brewing raw tea are particularly provided.
