Embodiment Construction

[0009] Further illustrate the present invention by specific content below: raw material adopts Pu'er cooked tea that Yunnan Academy of Agricultural Sciences Tea Research Institute provides, and solvent is purified water or 95% edible alcohol.

[0010] The instrument adopts a pulverizer, a vacuum condensation reflux extraction and concentration unit manufactured by Zhejiang Benuo Machinery Factory, a vacuum drying oven produced in Zhejiang, a fresh-keeping film and a plastic mold. Steps:

[0011] 1. Pulverization: Puer ripe Pu'er tea is pulverized with a pulverizer to obtain 60-mesh tea powder for later use.

[0012] 2. Extraction: Take a certain amount of Pu’er tea powder, wrap it with gauze, add a small amount of pure water to make it moist, and then put it into a vacuum condensation reflux extraction tank with a reflux device and a thermometer. The tea water is in a mass ratio of 1: (8-12) was added, leached at a temperature of 80°C-100°C for 15 minutes to conduct an orthog...

Abstract

The invention relates to a process for extracting Pu'er tea paste by a heated refluxing method, which comprises the following steps of: taking Pu'er tea as a raw material, drying and pulverizing to obtain tea leaf powder with 60 meshes, wrapping the tea powder by a gauze, putting into a vacuum condensation refluxing extraction tank according to a certain tea-water ratio, heating, refluxing and leaching for 15min at the temperature of 80-100 DEG C; filtering an extracting liquid in an extraction tank, sucking into a concentration tank, carrying out vacuum concentration, concentrating into a concentrated liquid with the dry substance content of 30-40%, drying the concentrated liquid into a tea paste block with the water content of 16% and molding and pressing by a mould to obtain the Pu'er tea paste after pulverizing the tea paste. The Pu'er tea paste is extracted by utilizing the advanced techniques of heated refluxing leaching, decompressing filtration, vacuum concentration, vacuum drying and the like, thereby enabling the preparation process of the modern Pu'er tea paste to be more scientific, simpler, more convenient and more sanitary and being beneficial to increasing the valueof a tea leaf product and saving resources; and the quality of the obtained product can be better guaranteed, and the process is easy for industrialized production.

Description

[0001] Technical field: the invention belongs to the field of tea products, in particular to a process for extracting Pu-erh tea cream by heating and refluxing. Background technique: [0002] Pu'er tea paste is the essence extracted from Pu'er tea. Compared with Pu'er tea, it has high nutritional value and drinking value, and has higher nutritional value; it has good portability, and the brewing process is simple, convenient and hygienic. Consumers' favor and pursuit. In addition, Pu'er tea paste has many medicinal effects, such as abdominal distension, cold, mouth and throat, swelling and pain due to heat, and heat. According to modern research, Pu'er tea cream has health effects such as lowering blood fat, lowering blood pressure, lowering blood sugar, anti-fatigue, anti-aging, improving microcirculation, preventing atherosclerosis and cardiovascular and cerebrovascular diseases. According to traditional Chinese medicine, Pu'er tea paste has health effects such as clearing ...
