Process method for preparing green tea cakes by using finished product loose green tea and product

Abstract

The invention discloses a process method for preparing green tea cakes by using a finished product loose green tea and a product. The process method comprises: humidifying and softening the finished product loose green tea; (2) feeding the humidified and softened finished product loose green tea into a moulding press for mould pressing to preset-shaped green tea cakes; and (3) drying the green tea cakes which are mould-pressed to the preset shape to a predetermined certain moisture content. The process method is characterized in that the specific process of humidifying and softening the finished product loose green tea comprises: (1) immersing the finished product loose green tea in a tea juice liquid prepared by the green tea to be humidified and softened in a special container; and (2) removing residual tea juice water by using a centrifugal dehydrator to obtain the softened finished product loose green tea. The process provided by the invention overcomes a major defect that the quality of tea leaves is deteriorated in an existing steam humidifying and softening process, and the prepared green tea cakes are excellent in quality.

Description

technical field [0001] The invention relates to a process and a product for preparing green tea cakes from green tea finished loose tea. Background technique [0002] At present, the green tea cake that adopts the green tea finished loose tea preparation to appear on the market. Because it is easy to pack and carry, and not easy to deteriorate, it is very popular in the market. But because there is defect in technical process, the quality and local flavor of green tea tea cake are very poor. Affected the market of green tea cake. Adopt green tea finished loose tea to prepare green tea tea cake, the most important technical aspect is exactly how to make the green tea tea cake of making, keep the original local flavor and the quality of green tea. In the existing process, the process of humidifying and softening green tea raw material tea is generally: 1) humidifying and softening with steam at high temperature for a short time; 2) humidifying and softening by spraying wate...

AI Technical Summary

Problems solved by technology

Due to the low softening temperature and humidity of water spraying at room temperature, it takes a long time for softening, usually several hours, and it will cause a "stack" effect in the later stage, and the temperature will rise

The above process exists in a high temperature and high oxygen environment, or a high temperature and high oxygen environment under the effect of "stacking" for a long time, resulting in serious non-enzymatic oxidation of tea leaves, causing further fermentation of tea leaves, and changing the quality of green tea raw tea
