Problems solved by technology

[0002] The traditional way of eating tea is to make tea, but there are two disadvantages in making tea: one is time-consuming and not suitable for the fast-paced modern life; the other is the low utilization rate of active ingredients in tea, especially those that are difficult to dissolve in water Proteins, vitamins, chlorophyll, and trace elements cannot dissolve into water and are often discarded with slag
Although this production process can obtain relatively pure ultra-fine tea powder of more than 300 mesh or even 500-600 mesh, the process is complicated and the cost is high, especially after leaching, the aroma components and other beneficial components in the tea are volatilized or lost. , In addition, there are some ingredients that cannot be extracted, or chemical reactions have occurred during the extraction process. Therefore, although the ultrafine tea powder obtained by this process has a small particle size, it has poor taste and nutritional effect.

Embodiment 1

[0024] The ultra-fine tea powder preparation process comprises the following steps:

[0025] a. Select fresh green tea leaves as raw materials, kill enzymes, sterilize, and sort; then dry the surface moisture by air at minus 20 degrees; then dry to make the water content as low as 2.5%; then use high-speed air The tube is cooled and crushed into flakes, impurities are removed, stems are removed, and then put into an electric ultrafine pulverizer to pulverize to obtain tea powder;

[0026] B, the tea powder grain that step 1 obtains is sent into the bottom of collection chamber 1 through the entrance 21 of collection chamber, as figure 1 Shown, and make the stirring blade 2 rotation that is positioned at collection chamber bottom, the rotating speed of stirring blade 2 is 4000 rev / s, and the diameter of stirring blade is 18 centimetres, and the rotation of stirring blade stirs the tea powder grain in the collection chamber, makes tea The powder particles are flying up (as show...

Embodiment 2

[0030] The ultra-fine tea powder preparation process comprises the following steps:

[0031] a. Select fresh green tea leaves as raw materials, kill enzymes, sterilize, and sort; then dry the surface moisture by air at minus 15 degrees; then dry to make the water content as low as 3.0%; then use high-speed air The tube is cooled and crushed into flakes, impurities are removed, stems are removed, and then put into an electric ultrafine pulverizer to pulverize to obtain tea powder;

[0032] b. Send the tea powder obtained in step 1 into the lower part of the collection chamber, and rotate the agitating blade located at the lower part of the collection chamber. The rotating speed of the agitating blade is 5000 rpm, and the diameter of the agitating blade is 20 cm for use to agitate the tea powder At the same time, air is blown into the bottom of the collection chamber, and the air blown in is filtered by a filter; at the upper part of the collection chamber, 3.5 meters above the ...

Embodiment 3

[0034] The ultra-fine tea powder preparation process comprises the following steps:

[0035] a. Select fresh tea leaves as raw materials, kill enzymes, sterilize, and sort; then dry the surface moisture by air at minus 15 degrees; then dry to make the water content as low as 2.5%; then use high-speed air duct Cool and break into flakes, remove impurities, pick stems, and then put it into an electric ultrafine pulverizer to pulverize to obtain tea powder;

[0036] b. Send the tea powder obtained in step 1 into the lower part of the collection chamber, and rotate the agitating blade located at the lower part of the collection chamber. The rotating speed of the agitating blade is 3000 rpm, and the diameter of the agitating blade is 15 cm for use to agitate the tea powder At the same time, air is blown into the bottom of the collection chamber, and the air blown in is filtered by a filter; at the upper part of the collection chamber, 1.5 meters above the central axis of the stirri...

Abstract

The invention provides a process for preparing ultra refined tea powder, which comprises the steps of: (1) subjecting fresh tea to enzyme eradication, sterilizing, drying, disintegrating and edulcoration, obtaining tea powder granules, (2) loading the obtained tea powder granules into the lower portion of a gathering chamber, agitating and collecting tea powder waving on the top portion of the gathering chamber.

Description

technical field [0001] The invention belongs to the preparation technology of tea food, and in particular relates to a preparation technology of ultra-fine tea powder. Background technique [0002] The traditional way of eating tea is to make tea, but there are two disadvantages in making tea: one is time-consuming and not suitable for the fast-paced modern life; the other is the low utilization rate of active ingredients in tea, especially those that are difficult to dissolve in water Proteins, vitamins, chlorophyll, and trace elements cannot dissolve into water and are often discarded with slag. [0003] Therefore, with the diversification of people's consumption patterns, in recent years, the "eating tea" method of "edible tea powder" has replaced the dominant position of "making tea" to a certain extent. The smaller the particle size of the edible tea powder, the better, so that a smooth taste can be obtained, and the entrance has no slag feeling, and the chlorophyll an...
