Embodiment 1

[0047] Example 1: A heat-dissolving quick-soluble red tea powder production process, such as figure 1 As shown, including the following steps to obtain:

[0048] Step 1, leaching: In deionized water at a temperature of 85 ° C, red blouse is added to deionized water according to the ratio of the weight of the deionized water and the redden tea, and 13 min, mix 13 min, and obtain tea soup;

[0049] Step 2, the slag separation: The first filtration process is performed using the horizontal helical pusher settling centrifuge, the rotation speed is 2700 rpm, and the time the filtration process is 3 min, and the rude filtrate is obtained;

[0050] Step three, cooling centrifugation: Cooling the crude filtrate obtained in step II to 65 ° C, after the secondary filtration treatment, the rotation speed of the secondary filtration is 5500 rpm, and the secondary filtration is passed for 3 min, and the clear liquid is obtained;

[0051] Step four, concentrated: concentrate the clear liquid ob...

Embodiment 2

[0054] Example 2: A production process of thermally soluble red tea powder, the difference from Example 1 is that in the disc separator used in step three, such as figure 2 As shown, including the multilayer annular disc 1, the through hole 2 is disposed on the disc 1, and the edge of the disc 1 is folded upward, and the vertical spacing between adjacent loop 3 is greater than. The vertical spacing between adjacent disc 1 is 150-175 ° between the ring sheet 3 and the outer surface of the disc 1.

Embodiment 3

[0055] Example 3: A heat dissolved velockel powder production process, the difference from Example 1 is that the temperature of the deionized water is 85 ° C, the weight of the reddenated tea added and deionized water added. The ratio is 10: 1, mixed for 10 min.

Abstract

A production process of hot-dissolving instant black tea powder, which belongs to the field of instant black tea powder production, step 1, leaching: in deionized water with a temperature of 85-90°C, according to the ratio of weight and number of deionized water to black crushed tea Add crushed red tea to deionized water at a ratio of 5-10:1, mix for 8-13 minutes, and obtain tea soup; step 2, separation of slag and liquid: use a horizontal screw pusher sedimentation centrifuge for the first filtration treatment to obtain crude Filtrate; step 3, cooling and centrifuging: cool the coarse filtrate to 60-65°C, and undergo a secondary filtration treatment. The rotation speed of the secondary filtration treatment is 5500-6200rpm, and the passing time of the secondary filtration treatment is 2-3min to obtain a clarified liquid Step 4, Concentration: Concentrate the clarified liquid to obtain a concentrated liquid with a solid content of 25-35wt%; Step 5: Sterilize and dry: After the concentrated liquid is sterilized by UHT, it is sprayed and dried. The production efficiency of the hot-melt instant black tea powder in the present invention is high, the content of theaflavins is high, and the production is not easily limited by time, so it is easy to realize industrialization.

Description

Technical field [0001] The present invention relates to the field of instant red tea powder production, and more specifically, it involves a production process of thermal solubility reduction red tea powder. Background technique [0002] Hot melt type speed red tea powder, ie, tea powder obtained by the black tea, no slag, ready to drink. The hot melt-easeous red tea powder has a good nutritional value. [0003] The process of traditional production of instant red tea powder mainly includes extracting the extraction of intermittent traditional Chinese medicine to extract, using a countercurrent extraction tank, and uses the three ways of cage. However, the above three ways takes a long time, and usually a batch of tea powder is taken from 8-12 h. In addition, the murine-cage extraction can only be used for production of a small amount of raw materials, and the limitations of the production conditions can cause the limitations of its unplanned production. [0004] In addition, the...
