Description

Technical Field

[0001] The utility model relates to tea experiment equipment, in particular to a white tea rapid aging experiment device. Background Art

[0002] After a period of storage, the content of tea polyphenols and amino acids in white tea decreases; caffeine does not change much; the aroma substances gradually disappear after a period of storage, and the characteristics of stale and sour taste appear. The most important nutritional component of aged white tea is the increase of flavonoids. Brass is a good antioxidant and can promote blood circulation. The content of flavonoids in Baihao Yinzhen is higher than that in Bai Mudan and Shoumei.

[0003] White tea will be affected by many factors during the aging process, such as temperature, humidity, time, etc., and it takes several years to reach the optimal state under natural aging conditions. If aging can be accelerated artificially, the production cycle of the product can be shortened and the quality can be improved. The existing technology lacks dedicated research equipment. For this reason, the inventor has developed this white tea rapid aging experimental device to facilitate the above research. Utility Model Content

DETAILED DESCRIPTION

[0018] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1-3 As shown:

[0020] A white tea rapid aging experimental device comprises an integrated cabinet 1, an ozone supply system, a humidifier, an electrical control cabinet and a control host. A plurality of compartments 2 with open front ends are arranged in the integrated cabinet 1, and the compartments 2 are all installed with sealed doors 21 at their openings; ultraviolet lamps 3 are installed on the top walls of the compartments 2, temperature-adjusting lamps 7 are installed on the side walls, and humidification branch pipes 5, oxygenation branch pipes 6 and integrated sensors 4 are installed on the rear walls in sequence; the humidification branch pipes 5 are all connected to the humidifiers through a humidification main pipe 52, and an electrically controlled throttle valve A51 is installed on the inlet side of the humidification branch pipes 5; the oxygenation branch pipes 6 are all connected to the ozone supply system through an oxygenation main pipe 62, and an electrically controlled throttle valve B61 is installed on the inlet side of the oxygenation branch pipes 6; the ultraviolet lamps 3, temperature-adjusting lamps 7, electrically controlled throttle valves A51, electrically controlled throttle valves B61, the ozone supply system, the humidifier, and the integrated sensor 4 are all connected to the integrated control cabinet, and the control host is connected to the electrical control cabinet.

[0021] The utility model arranges a plurality of compartments 2 on an integrated cabinet 1 so that batches of white tea rapid aging experiments can be carried out. Each compartment 2 is separately provided with an ultraviolet lamp 3, a temperature-adjusting lamp 7, a humidifying branch pipe 5 and an oxygenating branch pipe 6, and collects data for supervision and feedback control through a separate integrated sensor 4. The ultraviolet lamp 3 and the temperature-adjusting lamp 7 are both panel-type to increase the uniformity of lighting and heating. The integrated sensor 4 at least includes a temperature sensor, a humidity sensor and an ozone concentration sensor.

[0022] The control host, i.e., the computer, is mainly used to input experimental parameters and set the corresponding temperature, humidity, ozone concentration, and ultraviolet light intensity for each compartment 2.

[0023] The electrical control cabinet mainly integrates electrical control circuits, receives control parameters from the control host and feedback parameters from the integrated sensor 4, and adjusts the ultraviolet lamp 3, the temperature control lamp 7, the electric control throttle valve A51, the electric control throttle valve B61, the ozone supply system, and the humidifier.

[0024] Since the humidity and ozone concentration do not change frequently during the experiment, the utility model can adjust the humidity and ozone concentration for all compartments 2 through a set of ozone supply system and humidifier, in conjunction with the electronically controlled throttle valve A51 and the electronically controlled throttle valve B61 (since the experimental parameters are higher than the normal environment in the laboratory, the temperature, humidity and ozone concentration are all reduced by dissipation, which is a supplementary adjustment), which greatly reduces the cost. When the electrical control cabinet receives the humidity and ozone concentration signal fluctuations of the integrated sensor 4 greater than the threshold, the humidifier or ozone supply system is started, and the electronically controlled throttle valve A51 or the electronically controlled throttle valve corresponding to the compartment 2 is opened, and the humidity and ozone concentration are slowly increased until they return to the set range.

[0025] The different experimental parameters are set as follows:

[0026] 1. Study the effect of different temperatures on the rapid transformation of white tea aroma

[0027] Three-year-old white tea was used as a control, and the setting time was 12 weeks, the humidity was 40%, and the new white tea was stored in compartments 2 at 25℃, 35℃, 45℃, and 55℃, respectively, and ventilation was performed every other week to study the effect of storage temperature on the aroma quality of white tea. The sensory quantitative description and analysis of the aroma of the samples taken can be performed in compartments 2 with larger intervals to avoid the temperature influence between each other, and the gaps between adjacent compartments 2 in the integrated cabinet 1 can also be filled with insulation materials 11 to reduce the temperature influence between each other.

[0028] The volatile components of the samples were detected by GC-MS.

[0029] WGCNA co-expression network analysis was used to explore the correlation between volatile substances and aroma sensory evaluation, and to identify the volatile substances that affect different sensory attributes of old white tea.

[0030] The sensory quantitative description results were combined with GC-MS monitoring data to determine the optimal aging temperature.

[0031] 2. Study the effect of different humidity on the rapid transformation of white tea aroma

[0032] Three-year-old white tea was used as a control. The storage time was set to 12 weeks and the storage temperature was 35°C. The new white tea was stored in compartment 2 with humidity of 30%, 40%, 50%, and 60%, respectively. The storage was ventilated every other week to study the effect of storage humidity on the aroma quality of white tea. The samples were subjected to sensory quantitative description and volatile component detection.

[0033] WGCNA co-expression network analysis was used to analyze the properties of volatile substances and identify key aroma substances.

[0034] The sensory quantitative description results are combined with GC-MS monitoring data to determine the optimal aging humidity.

[0035] 3. Study the effect of aging time on the rapid transformation of white tea aroma

[0036] The three-year-old white tea was used as the control, the temperature was set to 35°C, the humidity was 40%, and the irradiance of the UV lamp 3 in compartment 2 was 0w / M 2 、30w / M 2 、40w / M 2 、50w / M 2 The new white tea was aged with ozone concentrations of 1ppm, 20ppm, 30ppm, and 40ppm. The tea was ventilated every other week and samples were taken every 2 weeks, for a total of 6 times, to study the effect of storage time on the aroma quality of white tea.

[0037] UV lamp 3 irradiance is 0w / M2 , compartment 2 with an ozone concentration of 1 ppm represents a natural indoor storage environment, while other compartments 2 accelerate aging through UV light 3 irradiation and ozone, so as to study whether the same aging effect as natural aging for a longer time can be achieved in a shorter time under the condition of artificially increasing irradiance and ozone oxidation.

[0038] The samples were subjected to sensory quantitative description and analysis according to the green aroma, fresh fragrance, floral and fruity aroma, aged aroma, woody and medicinal aroma, and sweet aroma.

[0039] The volatile components of the samples were detected by GC-MS.

[0040] WGCNA co-expression network analysis was used to explore the correlation between volatile substances and aroma sensory evaluation, and to identify the volatile substances that affect different sensory attributes of old white tea.

[0041] The sensory quantitative description results were combined with GC-MS monitoring data to determine the optimal aging time, optimal irradiance for artificial accelerated aging, and ozone concentration.

[0042] Since each compartment 2 of the utility model has individually controlled parameters, the above experiments can be carried out simultaneously in theory, which greatly reduces time and labor costs and improves the efficiency of the experiment. The compartments 2 are arranged in a rectangular array, with 5-6 compartments per row, because the variables of the same experiment have a maximum of 5-6 values, so each row can complete an experiment, which is easy to manage.

[0043] In order to facilitate supervision, a display 22 is installed on the sealed door, and the display 22 is connected to the electrical control cabinet, mainly used to display the compartment 2 number, working status, temperature, working time, humidity, ozone concentration, etc.

[0044] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
