Embodiment Construction

[0045] like Figure 1 to Figure 12As shown, an integrated system for sorting and fixing green tea includes a heat exchange unit and a fixing and sorting tower.

[0046] like image 3 As shown, the fixing and sorting tower includes a tower body 2, and the tower body 2 is sequentially provided with a cleaning chamber 3, a fixing chamber 4, a primary heat exchange chamber 5, a secondary heat exchange chamber 6 and a sewage chamber from top to bottom. Object Pool 7. The tower body 2 is a cylindrical structure with two conical ends and a cylinder in the middle, and the inner and outer parts of the cylindrical part in the middle are respectively provided with an inner insulation layer 21 and an outer insulation layer 22. The materials of the inner heat preservation layer 21 and the outer heat preservation layer 22 are heat preservation and refractory materials, and the fireproof performance is Class A.

[0047] The tower body is provided with an observation window that can observ...

Abstract

An integrated system for green tea sorting and de-enzyming comprises a heat exchange unit and a de-enzyming and sorting tower. A cleaning chamber, a de-enzyming chamber, a primary heat exchange chamber, a secondary heat exchange chamber and a sewage pool are sequentially arranged in a cavity formed in a tower body of the de-enzyming and sorting tower from top to bottom, and a spraying device and high-pressure atomizing spray heads are arranged in the cleaning chamber; the de-enzyming chamber is arranged under the cleaning chamber, the side wall of the a tower body of the de-enzyming chamber is provided with three spray pipes which are evenly arranged by surrounding the axis of the tower body at the same height, each spray pipe is obliquely arranged along the interior of the tower, the primary heat exchange chamber is arranged under the de-enzyming chamber, and heat exchange boxes are arranged in the primary heat exchange chamber; the secondary heat exchange chamber is arranged under the primary heat exchange chamber, the sewage pool is arranged under the secondary heat exchange chamber, and an air blower is arranged between a hot air outlet and the heat exchange unit. Accordingly, impurities in tea leaves are fully and completely stripped, tea leaves with the clean surfaces are obtained, and the cleaning and de-enzyming functions are achieved.

Description

technical field [0001] The invention relates to equipment and a system for sorting and fixing fresh tea leaves. Background technique [0002] The green tea processing process generally includes sorting, fixing, rolling and drying. The purpose of fixing is to rapidly inactivate oxidase, especially polyphenol oxidase and peroxidase, thereby preventing the production of tea polyphenols (mainly catechins). Oxidation; on the one hand, the rolling process is to shape, on the other hand, the cells of the green leaves are broken, the tea juice overflows, and the contents are further transformed; drying is also a thermochemical effect, the main function is to further remove moisture, and at the same time form aroma and promote esters Type complex catechins are further converted to simple catechins. The organic combination of greening, rolling and drying processes has formed the unique quality characteristics of green tea, such as green color, strong flavor, high fragrance and freshn...
