Problems solved by technology

[0004] At present, the production of immortal flowers has the following types: 1. Chemical solution immersion method: use the liquid agent to replace and retain water to make dried flowers; disadvantages: liquid agent leakage and flower materials are prone to mildew in high temperature environments , darker colors, etc.
2. Natural drying method: the method of removing moisture from plant materials through the natural circulation of air, which is the most primitive and simplest drying method; disadvantages: it takes a long time, and is suitable for many fibers, low water content, and flower patterns. Small, short-stemmed plant material
3. Vacuum freeze-drying method: The principle of vacuum freeze-drying method is that the vacuum freeze-drying machine (referred to as freeze-drying machine) pre-freezes the moisture in the flowers, and then sublimates the moisture of the flowers in a vacuum state to obtain a technical method of drying items. The shape and color of the flowers treated by the freeze dryer are easy to store for a long time. After adding water, they can return to the state before freeze-drying and maintain the original biochemical characteristics; disadvantages: cannot be exposed to the air, once exposed to the air, it will absorb air The moisture in the water will change the shape of the original flowers and lose the ornamental effect
However, limite

Embodiment 1

[0041] Embodiment 1 A kind of deep processing method of fresh flowers

[0042] (1) Flower pruning and pre-water retention treatment: take the flowers picked within 24 hours, remove withered and incomplete petals, insert them in water to absorb water, and keep the water content of the petals at 90%;

[0043](2) Dehydration: Put the flowers obtained in step (1) into the freeze dryer, close the airtight door, turn on the switch of the vacuum pump and the switch of the freeze dryer, pump the vacuum to 15kPa, start the refrigeration at the same time, and freeze and dry the flowers within 2 hours The temperature inside the freeze dryer is reduced to -40°C and kept for 2 hours, after that, the temperature inside the freeze dryer is raised to 15°C within 30 hours to dry the flowers;

[0044] (3) Softening and bleaching: Soak the flowers treated in step (2) in the ethanol-hydrogen peroxide mixture with a volume ratio of 1:2, and add 12mL / flower to the ethanol-hydrogen peroxide mixture ...

Abstract

The invention discloses a deep processing method for fresh flowers. The deep processing method comprises the following steps of trimming and pre-moisturizing the fresh flowers; dehydrating; softeningand bleaching; shaping; filling a medium, dyeing and color fixing, specifically, using a solution containing PEG 200, PEG 400, PPG 600, ethanol, benzoic acid, food pigment, peregal o-25 leveling agentand formaldehyde-free color fixing agent TS-102 to carry out filling the medium, dyeing and color fixing on the fresh flowers after shaping; and washing, drying and packaging. The method provided bythe invention is suitable for the deep processing of 85% or above of fresh leaves, 75% of the fresh flowers and 25% of fruits in the nature; and according to the processing method provided by the invention, the storage time of the fresh flowers can be prolonged, and the good shape and the glossiness of the fresh flowers can be kept.

Description

technical field [0001] The invention relates to the field of decorations, in particular to the technical field of intensive processing of flowers. Background technique [0002] Eternal flowers, also known as preserved flowers, ecological flowers, and flowers that never fade, are fresh-cut flowers of roses, carnations, camellias, eustomas, peonies, hydrangeas, and various leaves. Dried flowers processed by a series of complex processes such as dehydration, decolorization, softening, solidification, dyeing, and drying can generally be stored for 2-3 years, or even 5-8 years. Preserved flowers have changed the shortcomings of the previous fresh-cut vases, which have short lifespan and short viewing period, and greatly prolong the viewing life of flowers. Preserved flowers are novel and have high ornamental value. They are suitable for interior decoration, home display, wedding scene, sending relatives, friends and lovers to express friendship, etc., and are very popular among ...
