Problems solved by technology

But in this processing method, the temperature of steam blanching is as high as 100°C, the temperature range of hot air drying is as high as 80-100°C, and the temperature range of freeze-drying is as low as -15--30°C. The original color of flowers also makes golden camellia easy to collapse and deform during the heating process. Although it makes up for the shortcomings of high or low temperature to a certain extent by shortening the processing time, it does not affect the original color and color of golden camellia flowers. Shape protection is still not ideal

Embodiment 1

[0011] To pick camellia flowers, choose flowers with buds and petals without discoloration and damage. After picking, it is used to prepare dried scented tea that maintains the original color of Camellia camellia flowers. The preparation process is as follows:

[0012] 1) Electrostatic field drying: Place the fresh flowers in a metal shaping mold and put them into an electrostatic field dryer for rapid dehydration and drying at low temperature. The drying temperature is set at 12°C and the drying time is 10 hours to obtain the primary product of dried scented tea;

[0013] 2) Air-drying with cold air: Take the primary dried scented tea and dry it with cold air at a temperature of 10°C for 3 days. The moisture content of the primary dried scented tea will drop to 4.4%, and the dried scented tea that maintains the original color of the flowers of Camellia japonica can be obtained.

[0014] The prepared dried scented tea has a strong aroma and is full of the unique fragrance of C...

Embodiment 2

[0016] To pick camellia flowers, choose flowers with buds and petals without discoloration and damage. After picking, it needs to be transported, and the preparation process is as follows: 1) Preservation treatment: use 8°C pure water to atomize and spray Camellia camellia flowers, and then put them into fresh-keeping bags filled with air holes on the surface, 100 flowers per bag, to ensure golden The flowers of scented tea will not be damaged; pack and transport the fresh-keeping bags filled with flowers of Camellia japonica, use plastic boxes or foam boxes with ventilation holes when packing, and store them for later use after transportation. The total time of packing, transportation and storage is 2.5 Hour;

[0017] 2) Low-temperature drying in an electrostatic field: place the fresh flowers in a metal shaping mold and put them into an electrostatic field dryer for low-temperature rapid dehydration and drying. The drying temperature is set at 15°C and the drying time is 8 h...

Abstract

The invention discloses a preparation method of dried flower tea keeping a natural original color and a shaped flower shape of camellia nitidissima. The preparation method comprises the following steps: drying in an electrostatic field and airing by cold air. The step of drying in the electrostatic field comprises the following steps: putting fresh flowers into a metal shaping model to be shaped and then putting the shaped fresh flowers into an electrostatic field drying machine to be rapidly dehydrated and dried at a low temperature, wherein the drying temperature is 12-15 DEG C and the drying time is 8-10 hours; and finally, preparing a flower tea primary product. The step of airing by the cold air comprises the following steps: taking the flower tea primary product and drying the flower tea primary product by the cold air at 5-15 DEG C for 3 days until the water content is less than or equal to 5% to obtain the dried flower tea keeping the natural original color and the shaped flower shape of camellia nitidissima. According to the dried flower tea prepared by the method, the original color and the natural shape of the fresh flowers of camellia nitidissima are kept better and the quality of the dried flower tea can be improved.

Description

technical field [0001] The invention relates to the technical field of flower processing, in particular to a preparation method of dried flower tea which keeps the natural primary color and shape of camellia camellia. Background technique [0002] The traditional processing methods of Camellia japonica mainly include drying and frying. However, the weather of the sun-drying method changes greatly, is uncontrollable, and easily causes the product to deteriorate; the temperature of the frying method is also difficult to control, which easily makes the product burnt and blackened, reducing the quality of the product. Above-mentioned two kinds of processing methods all can make a lot of active ingredients of golden camellia tea lose, directly affect the quality of product. In order to improve the quality of camellia camellia scented tea, some new processing methods and related patent documents have appeared. For example, Chinese patent application CN200710148634.1 discloses a ...
