Preparation method of honeysuckle tea

Abstract

The invention provides a preparation method of honeysuckle tea, which comprises the following steps: picking honeysuckle buds without water on the surfaces before flowering, heating for 5-10 minutes by normal-pressure steam for fixation, uniformly distributing on a drying sieve tray, putting into a drying oven, drying for 2-3 hours under the conditions that the temperature is 35-45 DEG C and the relative humidity is lower than 50%, and taking out; and drying for 2-3 hours under the conditions that the temperature is 45-55 DEG C and the relative humidity is lower than 40%, finally drying for 1-2 hours under the conditions that the temperature is 65-70 DEG C and the relative humidity is lower than 30%, selecting and packaging to obtain the honeysuckle tea. According to the method disclosed by the invention, temperature control and humidity control are combined, low-temperature dehydration and drying of the honeysuckle are realized by dehumidifying internal circulating hot air, the dehydration and drying time is shortened by about 1 / 3 to half, the energy consumption is reduced by more than 40%, and the loss of fresh scent is relatively small; and the prepared honeysuckle tea is good in appearance, water content, fresh scent and brewing and drinking effects.

Description

technical field [0001] The invention belongs to the field of tea production, and in particular relates to a preparation method of honeysuckle tea. Background technique [0002] Honeysuckle, also known as honeysuckle, its flowers bloom in spring, initially white, and then turn yellow, hence the name. [0003] Honeysuckle is a commonly used traditional Chinese medicinal material. It is cold in nature and sweet in taste. It enters the lung, heart and stomach meridians. It has the effects of clearing away heat and detoxifying, anti-inflammatory, tonifying deficiency and treating wind. and tumors. It is effective for dizziness, dizziness, dry mouth and thirst, excessive sweating, dysentery, enteritis, bacillary dysentery, measles, pneumonia, Japanese encephalitis, meningitis, acute mastitis, sepsis, appendicitis, skin infection, carbuncle and ulcer, erysipelas, mumps, Diseases such as suppurative tonsillitis all have certain curative effect. Modern studies have proved that hon...

Problems solved by technology

Due to concentrated large-scale planting, it is no longer possible to dry a large amount of high-quality honeysuckle tea by drying in the shade or drying under low light conditions. Therefore, low-temperature dehydration drying technology has been developed and applied. However, the existing low-temperature dehydration drying technology often focuses more on temperature control. The degree of attention to humidity control is often not enough, which affects the rationality of the dehydration and drying process of honeysuckle and the appearance and quality of honeysuckle tea products after dehydration and drying.

[0007] The existing technology removes the moisture released during the drying process of honeysuckle by continuously discharging the wet air flow; due to the long time of the low-temperature dehydration stage and the low moisture concentration in the wet air flow discharged under low temperature conditions, the low-temperature humidity The discharge volume of the airflow is very large, resulting in excessive loss of fragrance
