Method for preparing dewatered dry peony flowers

Abstract

The invention discloses a method for preparing dewatered dry peony flowers. The method comprises the following steps: adopting a 60-250-mesh sieve for screening cotton seed meal, thereby acquiring fine cotton seed meal; heating the acquired fine cotton seed meal at 40-90 DEG C and drying for 1-4h, thereby acquiring a dewatering substrate; supplying the bright-colored complete peony flowers in consistent size; reshaping the selected complete peony flowers; soaking the reshaped complete peony flowers into a citric acid solution in the mass concentration about 0.5-2.5% for 5-20min and performing color-protecting treatment; placing the complete peony flowers after the color-protecting treatment into a dewatering tank; embedding the peony flowers with the dewatering substrate acquired in the step 1), thereby dewatering, wherein while embedding, the temperature of the dewatering substrate is more than or equal to 40 DEG C and the dewatering time is 4-20h; and after completing the dewatering, removing the dewatering substrate, thereby acquiring the dewatered dry peony flowers. The dry flowers prepared according to the method provided by the invention have strong anti-mildew capacity and are long in storage time.

Description

technical field [0001] The invention belongs to the field of flower processing, in particular to a method for preparing dehydrated peony flowers. Background technique [0002] At present, the dried flower products on the dried flower market are mainly various small flowers or vines and grasses, which are mainly obtained by natural air drying. In recent years, microwave drying technology, vacuum drying technology, etc. have also been used internationally and domestically for large-scale dried flower production. There are also a large number of dried flowers displayed in flower expositions in China, but they are limited to small flowers. [0003] Peony (Latin scientific name: Paeonia suffruticosa Andr.) is different from other flowers because of its thin petals, soft texture, large and multi-layered flowers, and high water content. Most of the peonies are red series. Severe discoloration occurs, such as red and light red darken, purple red turns purple, and the original lust...

Problems solved by technology

[0004] The main method of processing dried flowers is the traditional silicate adsorption method, also known as the embedding method, one of which is the separation and embedding method. In this method, the flowers and branches and leaves are separated, dried separately, and then spliced; this method requires manual operation. , many procedures, heavy labor, inconvenient mass production; in addition, this method needs to separate the petals, so it cannot meet the drying needs of multi-round petal varieties

In the prior art, chemical techniques are also used to process fresh flowers and dried flowers. For example, freeze-drying technology is used to make dried flowers, which can better maintain the shape and color of dried flowers and prolong their shelf life; Small, the petals are extremely crisp, the texture is not ideal, the processing technology is not good, and the cost is extremely high
