Problems solved by technology

[0012] 1. In the traditional tea making process, fresh leaves are directly withered, greened, dried, and fermented after picking fresh leaves. During the production process, the tea is easily affected by the environment and the tea is polluted.
[0013] 2. High-temperature greening makes the enzymes in the tea lose their activity and lose their own value, and the chlorophyll is more destroyed
[0015] 4. High-temperature killing causes the loss of volatile substances in the tea leaves. The tea leaves are not resistant to brewing. The tea leaves have a strong smell of burnt smoke and a bitter taste. The freshly made tea cannot be drunk and it takes time to transform
[0016] 5. The traditional tea making process is based on personal experience. Different people make different tea products, and the same person cannot guarantee that every batch is good tea

Embodiment 1

[0050] A kind of Pu'er tea processing method, comprises the following steps:

[0051] Step 1: Picking fresh leaves: In fine weather, use the one-pinch-one-lift method to pick dew-free one-bud-two-leaf or one-bud-three-leaf before 11:00 noon, and lay the picked fresh leaves flat in a single layer placed in the picking container;

[0052] Step 2, pre-cooling: the picked fresh leaves are placed in a pre-cooler within 1 hour after picking, and pre-cooled to 8°C with a fresh leaf thickness of 10cm per layer;

[0053] Step 3, vacuum packaging: take out the pre-cooled fresh leaves and put them into vacuum packaging bags, and then use a vacuum packaging machine to vacuumize and seal the packaging;

[0054] Step 4, Ultrasonic rapid freezing: Take the vacuum-packed fresh leaves and put them into the ultrasonic freezer for rapid freezing to -30°C;

[0055] Step 5, high-voltage electrostatic water thawing: take the frozen fresh leaves, remove the packaging bag, and put them into a thawi...

Embodiment 2

[0061] A kind of Pu'er tea processing method, comprises the following steps:

[0062] Step 1: Picking fresh leaves: In fine weather, use the one-pinch-one-lift method to pick dew-free one-bud-two-leaf or one-bud-three-leaf before 11:00 noon, and lay the picked fresh leaves flat in a single layer placed in the picking container;

[0063] Step 2, pre-cooling: the picked fresh leaves are placed in a pre-cooler within 1 hour after picking, and pre-cooled to 6°C with a fresh leaf thickness of 12cm per layer;

[0064] Step 3, vacuum packaging: take out the pre-cooled fresh leaves and put them into vacuum packaging bags, and then use a vacuum packaging machine to vacuumize and seal the packaging;

[0065] Step 4, Ultrasonic rapid freezing: Take the vacuum-packed fresh leaves and put them into an ultrasonic freezer for rapid freezing to -50°C;

[0066] Step 5, high-voltage electrostatic water thawing: take the frozen fresh leaves, remove the packaging bag, and put them into a thawin...

Embodiment 3

[0072] A kind of Pu'er tea processing method, comprises the following steps:

[0073] Step 1: Picking fresh leaves: In fine weather, use the one-pinch-one-lift method to pick dew-free one-bud-two-leaf or one-bud-three-leaf before 11:00 noon, and lay the picked fresh leaves flat in a single layer placed in the picking container;

[0074] Step 2, pre-cooling: the picked fresh leaves are placed in a pre-cooler within 1 hour after picking, and pre-cooled to 5°C with a fresh leaf thickness of 15cm per layer;

[0075] Step 3, vacuum packaging: take out the pre-cooled fresh leaves and put them into vacuum packaging bags, and then use a vacuum packaging machine to vacuumize and seal the packaging;

[0076] Step 4, Ultrasonic rapid freezing: Take the vacuum-packed fresh leaves and put them into an ultrasonic freezer for rapid freezing to -60°C;

[0077] Step 5, high-voltage electrostatic water thawing: take frozen fresh leaves, remove the packaging bag and put them into a thawing box...

Abstract

The invention relates to the field of tea processing, and concretely relates to a Puer tea processing method. The method includes the following steps: step one, fresh leaves picking; step two, pre-cooling; step three, vacuum packaging; step four, ultrasonic rapid freezing; step five, high-pressure electrostatic water freezing; step six, hydrogen-rich small molecule water bubble cleaning; step seven, near-infrared vacuum low-temperature magnetic wave drying; step eight, frequency-conversion low-temperature pressing; and step nine, negative ion air cooling and drying. The preparation process ofthe invention is not easy to pollute tea leaves due to environmental impact, effectively retains enzyme activities and nutrients in tea leaves, facilitates long-term preservation, improves tea taste,and stabilizes tea quality.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a method for processing Pu'er tea. Background technique [0002] Pu'er tea is one of the six major teas in my country. It is mainly produced in Xishuangbanna, Lincang, Pu'er and other areas in Yunnan Province. It has unique quality characteristics. According to its processing technology and quality characteristics, Pu-erh tea is divided into two types: raw Pu-erh tea and cooked Pu-erh tea. [0003] In the prior art, the processing technology of Pu'er tea is divided into two parts: preliminary preparation and refining, and the processing flow generally includes six steps of withering (spreading for cooling), finishing, rolling, drying in the sun, refining and grading, and autoclaving. Compared with Pu'er tea (raw tea), Pu'er tea (cooked tea) adds two processes of wet water and pile fermentation. [0004] The processing steps of Shengpu are composed of fresh leaves of Yunnan big-lea...
