Problems solved by technology

[0008] (2) Patent CN 104041640A first soaks honeysuckle in water at 90°C to 100°C for 5s to 6s. After this step, all the enzymes in the honeysuckle have been inactivated, and it is impossible to continue oxidation and fermentation; After draining, its water content is still very high, and it is not suitable for kneading, otherwise it will be easily broken, affecting the appearance of the finished product, and reducing the production rate. The process combination of this patent is inconsistent with the basic processing theory

Embodiment 1

[0026] Embodiment 1, take the honeysuckle flower bud processing of big white stage as example.

[0027] 1. Flower picking

[0028] Choose fresh and mature big white flowers in spring, and finish picking before 9:00 in the morning. When picking, use the lifting method to pick flowers: pinch the flower stalk with your index finger and thumb, and use a little force with your index finger (do not pull hard to prevent mechanical damage) to pick the flowers. Place in a breathable strip or bamboo basket.

[0029] 2. Sunlight withering: spread the flowers in a bamboo tray with a thickness of 4 cm, put them on a withering rack, and carry out withering in the sun for 8 hours.

[0030] 3. Kneading: use 6CR-35 tea rolling machine to knead for 30 minutes, and deblock the flowers after kneading.

[0031] 4. Oxidation and discoloration: ferment at room temperature for 6 hours. It needs to be slightly adjusted mainly according to the indoor temperature. That is, the fermentation time is sho...

Embodiment 2

[0037] Embodiment 2, take spring silver flower processing as example.

[0038] 1. Flower picking

[0039] In mid-May, pick the newly opened silver flowers before 9:00 am. When picking, use the lifting method to pick flowers: pinch the flower stalk with the index finger and thumb, and use a little force with the index finger (do not pull it hard to prevent mechanical damage) to pick the flowers, and put them in a breathable strip or bamboo basket.

[0040] 2. Withering in the sun: Spread the flowers in a bamboo tray with a thickness of 6 cm, put them on a withering rack, and wither in the sun for 6 hours.

[0041] 3. Kneading: use 6CR-45 tea rolling machine to knead for 25 minutes, and deblock the flowers after kneading.

[0042] 4. Oxidation and discoloration: Ferment at room temperature for 4 hours, mainly adjusted slightly according to the indoor temperature, that is, the fermentation time is shorter when the temperature is high, and the fermentation time is longer when the ...

Embodiment 3

[0048] Embodiment 3, take autumn golden flower processing as example.

[0049] 1. Flower picking

[0050] In August, pick fresh and golden flowers before 9:00 am. When picking, use the lifting method to pick flowers: pinch the flower stalk with the index finger and thumb, and use a little force with the index finger (do not pull it hard to prevent mechanical damage) to pick the flowers, and put them in a breathable strip or bamboo basket.

[0051] 2. Withering in the sun: Spread the flowers in a bamboo tray with a thickness of 5 cm, put them on a withering rack, and wither in the sun for 4 hours.

[0052] 3. Kneading: use the 6CR-45 tea rolling machine to knead for 20 minutes, and deblock the flowers after kneading.

[0053] 4. Oxidation and discoloration: Ferment at room temperature for 4 hours, mainly adjusted slightly according to the indoor temperature, that is, the fermentation time is shorter when the temperature is high, and the fermentation time is longer when the te...

Abstract

The invention relates to honeysuckle black tea and a preparation method thereof. Golden flowers, silver flowers or to-be-bloomed big white flowers are taken as raw materials and wither under sun light for 4-8 hours till the water is desorbed to about 60%; the flowers are twisted for 20-30 minutes; the flowers are oxidized and discolored at the room temperature for 4-6 hours, the center thickness of a flower stack is about 10 cm, and the flower stack is manually turned for each 0.5 hour; the flower stack is dried by microwave drying equipment at the temperature of 80 DEG C-85 DEG C for 3-4 minutes; and the flowers are spread out, aired and subjected to fragrance extraction at the temperature of 90 DEG C-95 DEG C, and the honeysuckle black tea is prepared. The honeysuckle product produced by the invention has unique flavor due to specialty of raw materials and innovativeness of the process, original faint scent is changed into strong flower fragrance, conventional bitter taste is changed into sweet taste, and the palatability of the product is effectively improved. Meanwhile, research about the drinking effects on different people proves that the product can effectively overcome the defect of spleen and stomach symptoms due to cold of original honeysuckle products.
