Изобретение относитс к способам хранени чайного листа и может быть использовано на чайных фабриках первичной переработки.The invention relates to methods for storing tea leaves and can be used in tea factories of primary processing.

Известен способ хранени чайного листа путем, продувани сквозь слой листа воздуха с относительной влажностью 85-95% l .The known method of storing the tea leaf is by blowing air through the sheet with a relative humidity of 85-95% l.

Известный способ исключает дополнительные операции по раскладке листа на цементном полу и (через определенное врем ) подаче его ручным способом на переработку, что предохран ет лист от механических повреждений и снижени качества.The known method eliminates additional operations on laying out the sheet on the cement floor and (after a certain time) feeding it manually for processing, which protects the sheet from mechanical damage and deterioration.

Недостаток известного способа заключаетс в том, что указанные режимы не обеспечивают сохранение исходных качественных и количественных показателей сырь . Происходит частичное высушивание нежных частей хранившегос сырь преимущественно в поверхностных сло х, что уменьшает выход высоко- качественной продукции, а сравни-The disadvantage of this method lies in the fact that these modes do not ensure the preservation of the original qualitative and quantitative indicators of raw materials. Partial drying of tender parts of the stored raw material occurs predominantly in the surface layers, which reduces the yield of high-quality products, and compares

тельно энергичного протекани процесса дыхани в пределах указанной температуры часть сухих веществ тер етс безвозвратно . Кроме того, механически поврежденные места и места среза флеши при транспортировке листа подвергаютс более интенсивной, преждевременной фер)ментадии , что снижает качество продукции ча .Due to the vigorous flow of the breathing process within the specified temperature, a part of the dry matter is irretrievably lost. In addition, mechanically damaged places and cut-off points of the flush are subjected to more intense, premature fermentation when transporting the sheet, which reduces the quality of tea products.

Цель изобретени - повышение качества продукта и уменьшение потерь сухих вешеств.The purpose of the invention is to improve the quality of the product and reduce the loss of dry substances.

Поставленна цель достигаетс тем, что лист в конце хранени перед переработкой обрабатывают воздухом с температурой 36-4О С , относительной влажностью 65-75% в течение 6О- 9О мин.The goal is achieved by the fact that at the end of storage the sheet is treated with air at a temperature of 36-4 ° C and a relative humidity of 65-75% for 6 ° -9O minutes before processing.

Claims

Processing the tea leaf at the end of storage with heated air completely eliminates the overwetting of the leaf from the increased surface moisture and facilitates the physicochemical preparation of the leaf for subsequent technological processes, in particular, for the processes of twisting. PRI me R. A transported container for storing the tea leaves is supplied with artificial air that is ventilated with a fan at a certain rate. Air humidification is determined by one of the known methods. The thickness of the stored tea leaf layer fluctuates 0.4-1.2 m in guadels. After storing the tea leaf for 3 days. 8O minutes before its processing, the supply of humidified air is stopped and the air heated to 40 ° C is supplied from air with a relative humidity of 75% to evaporate the moisture and prepare the tea leaf for processing. After preparation, the tea leaf is processed according to a known technological scheme. The use of the proposed method of storing tea leaves provides the possibility of extending the period of pre-technological storage of raw materials, improving the quality of products, reducing the loss of solids, fsiko-himpchoskunz sheet preparation for subsequent technological process: shortening the cycle of technological processes of filling and refining. Claim method of storing tea leaf by blowing air through the layer with a relative humidity of 85-05%, characterized in that, in order to improve product quality and reduce the loss of solids, the leaf is treated with tek-saraaura 36- before storage. 40 ° C, relative humidity 65-75% for 60-9 O min.
