Method for hermetically drying fragrant plant petals

Abstract

The invention discloses a method for hermetically drying fragrant plant petals, comprising the following steps: A, selecting two disciform ceramic vessels of the same size which are slightly concave inward, and then heating the two ceramic vessels to 100-200 DEG C; B, placing the fresh fragrant plant petals on one heated ceramic vessel, and covering the other ceramic vessel thereon to form an enclosed space, wherein, the fresh fragrant plant petals can be contacted with inner walls of the ceramic vessels up and down; and C, applying pressure to the bottoms of the two ceramic vessels to increase airtightness between the two ceramic vessels for maintaining a fully enclosed space between the two ceramic vessels for 10-70 seconds to finally obtain the dried fragrant plant petals. In the method, by adopting common tools and simple operation steps, the fragrant plant petals can be dried, fragrance of the petals can be basically preserved and shapes and properties of the petals can be maintained, thus having wide application scope.

Description

technical field [0001] The invention relates to a drying process for plant petals, in particular to a method for sealing and drying fragrant plant petals. Background technique [0002] The drying process of scented plant petals has a long history in our country. As early as a hundred years ago, the tea-making process appeared in our country. The finishing process of the tea-making process is to use the heat in the wok to evaporate the water in the plants; The scented plants are placed in the sun, and the plants are air-dried naturally by using the sunlight and the circulating air. The frying or air-drying time is controlled for different scented plants to grasp the quality of the dried products. Honeysuckle is one of the most widely used health-care medicinal materials at present. It is sweet and cold in nature and fragrant in nature. It is sweet and cold in clearing away heat without hurting the stomach. It is a kind of heat venereal disease, and fresh honeysuckle is easy ...

Problems solved by technology

Honeysuckle is one of the most widely used health-care medicinal materials at present. It is sweet and cold in nature and fragrant in nature. It is sweet and cold in clearing away heat without hurting the stomach. It is a kind of heat venereal disease, and fresh honeysuckle is easy to rot after picking, so it needs to be dried for preservation. If the above two methods are used for drying, the temperature of the frying pan in the tea making process is too high, which is easy to destroy the medicinal properties of honeysuckle itself. High temperature will also volatilize the fragrance of honeysuckle itself, which will affect the medicinal effect of the dried product; if the sun and circulating air are used to dry naturally, the dried honeysuckle will generally be withered, making it unable to exert its due economic value. In response to the above problems, people have also adopted various methods to dry honeysuckle and other scented plants, such as putting fresh honeysuckle and other scented plants into a microwave oven, and using the instant high temperature to quickly evaporate the water. Although this drying method can retain honeysuckle and other scented plants Part of the aroma of aromatic plants, but because its temperature is higher than that of a frying pan, it is easier to destroy the medicinal properties of honeysuckle and other aromatic plants and affect their medicinal value
