Embodiment 1

[0017] Embodiment 1: as figure 1 The tea dehydration dryer, which includes a shell 1 with a cover and a drain pipe, a drum 2 is arranged inside the shell 1, and a small drainage hole and an annular spacer are provided on the wall of the drum 2, and the drum 2 The bottom is provided with a sprocket or a pulley, and is connected with the motor 3 through a transmission mechanism. The housing 1 and the drum 2 are made of iron, preferably stainless steel.

[0018] Before the drying process of tea making, the centrifuge dehydration method of the above-mentioned tea dehydration dryer is used to assist the drying of tea leaves. The speed is 2000-2500 rpm, the diameter of the drum is 0.25 meters, and the centripetal acceleration can reach 6000-8500 m / s 2 . The centrifugation time is 5-6 minutes, which can shake off the moisture, pectin and tea juice contained in the tea leaves, remove the bitterness and enhance the chestnut aroma, and then take out the tea leaves and continue drying ...

Embodiment 2

[0021] Such as figure 1 According to the tea dehydration dryer, on the basis of embodiment 1, there are vent pipes 5 on both sides of the housing 1, and while the tea leaves are dehydrated by a centrifuge, dry hot air at 150 ° C is introduced from the vent pipe 5 to heat the tea leaves. When the pectin and tea juice in the tea water are thrown out, the tea leaves can be dried, and the drying speed is faster.

Embodiment 3

[0023] Such as figure 1 According to the tea dehydration dryer, on the basis of embodiment 2, heating plates 4 are provided on both sides of the inner wall of the housing 1, and the heating plates 4 can be infrared heating devices or electric heating wire heating devices. While the tea leaves are dehydrated by a centrifuge, air is blown in from the ventilation pipe 5, and the heating plate 4 is energized, and the tea leaves can also be dried when the pectin and tea juice of the tea moisture are thrown out, and the drying speed is also very fast. .

Abstract

The invention discloses a tea dehydrating and drying method. Tea drying is assisted by adopting a centrifuge dehydration mode before a tea-making drying process or during the drying process. According to the tea dehydrating and drying method, the tea leaves are dried in an assisted mode by adopting a centrifugal force dehydration principle, the pectin and tea liquor contained in the moisture of the tea can be thrown out, the bitterness is removed, the drying time during the tea making is greatly saved, the taste and the quality of summer and autumn tea are improved, the tea making period is shortened, the method is a novel process for drying the summer and autumn tea, and due to the treatment mode, sanitary and environment-friendly effects are achieved.

Description

technical field [0001] The invention belongs to the field of tea processing, in particular to a method for dehydrating and drying tea. Background technique [0002] Tea is one of the three major natural and environmentally friendly drinks in the world. Tea tasting is also a tradition in my country. Tea contains catechins, cholestenone, caffeine, inositol, folic acid, pantothenic acid and other ingredients, which can improve human health. However, the output of spring tea is far from enough. Although the output of summer and autumn tea is abundant, the quality, taste, and mouthfeel of tea are poor due to the large amount of pectin juice and bitter taste. [0003] Therefore, how to improve the quality of summer and autumn tea is particularly important. Contents of the invention [0004] The purpose of the present invention is to improve the quality of summer and autumn tea, and to provide a tea dehydration and drying method. [0005] The technical scheme adopted for achiev...
