Description
Известные способы контрол процесса ферментации ча не обеспечивают требуемой точности и продолжительны.Known methods of controlling the fermentation process do not provide the required accuracy and are long lasting.
Предлагаемый способ контрол процесса ферментации ча не имеет этих недостатков и позвол ет установить оптимальное врем прекращени процесса ферментации. Это достигаетс тем, что ведут наблюдение за скоростью поглощени кислорода воздуха ферментирующимс чаем и момент прекращени ферментации определ ют по наступлению стабилизации скорости поглощени кислорода.The proposed method for controlling the fermentation process does not have these drawbacks and makes it possible to establish the optimal time for the termination of the fermentation process. This is achieved by observing the rate of absorption of oxygen in the air by fermenting tea, and the time at which fermentation stops, is determined by the onset of stabilization of the rate of oxygen absorption.
Способ осуществл ют следующим образом. В несколько стекл нных сосудов объемом 0,5 л -помещают по 50 г ферментируемого ча первой и третьей фракции. Образцы .первой фракции помещают в сосуды через 2,5 час от начала скручивани , а образцы третьей фракции через 3 час от начала скручивани . Сосуды с чаем герметически закрывают и, наблюда за присоединенным к ним манометрам, отмечают скорости поглощени чаем кислорода. Через каждые 15 мин отсчитывают изменение давлени в каждом манометре и посредством крана на соединительной трубке уравнивают давление в сосудах с атмосферным.The method is carried out as follows. 50 g of fermented tea of the first and third fractions are placed in several glass vessels with a volume of 0.5 l. Samples of the first fraction are placed in the vessels after 2.5 hours from the start of twisting, and samples of the third fraction after 3 hours from the beginning of turning. The vessels with tea are hermetically sealed and, observing the pressure gauges attached to them, note the absorption rates of the tea by oxygen. Every 15 minutes, the pressure change in each manometer is counted and the pressure in vessels with atmospheric pressure is equalized by means of a valve on the connecting tube.
В процессе ферментации ча показани манометров снижаютс . Количество поглощаемого кислорода постепенно уменьщаетс - По наступлению стабилизации скорости поглощени кислорода определ ют момент прекращени процесса ферментации.During the fermentation process, the readings of the gauges are reduced. The amount of absorbed oxygen gradually decreases. When the rate of oxygen absorption stabilizes, the moment of termination of the fermentation process is determined.
Г1рименение описанного способа облегчает производство ча и обеспечивает улучщение его качества.The use of the described method facilitates the production of tea and improves its quality.
Способ контрол процесса ферментации ча , отличающийс тем, что, с целью установлени оптимального времени прекращени процесса , ведут наблюдение за скоростью поглощени кислорода воздуха ферментирующимс чаем и момент прекращени ферментации определ ют по наступлению стабилизации скорости иоглощеци кислорода.The method of controlling the process of fermentation of tea, characterized in that, in order to establish the optimal time for stopping the process, monitor the rate of absorption of oxygen in the air by fermenting tea and the time of termination of fermentation is determined by the onset of stabilization of oxygen absorption rate.
