Problems solved by technology

The traditional chrysanthemum processing is simply drying fresh chrysanthemums into dry chrysanthemums, but does not consider the recovery and utilization of volatile oil in the process, and even ignores the development and utilization of volatile oil in leaves, resulting in the loss of a large amount of volatile oil, so that every year 11 The origin of chrysanthemums in the month is always "fragrant ten miles", causing a great waste of resources

Embodiment 1

[0025] Example 1: After the fresh medicinal chrysanthemum enters the automatic de-enzyme drying machine, it is first de-enzymed at a high temperature of 100°C for 50s; , within 2 to 6 hours of drying time, collect the generated water-oil mixed steam and enter the condenser, cooling tower cooling and oil-water separator in turn for oil-water separation. After the oil-water is fully separated, open the oil-water separator to collect the upper oil layer. Volatile oil, collect the lower water layer to obtain aromatic water, and the recovery of aromatic water should not exceed 1.5 to 2 times the fresh weight of medicinal chrysanthemums.

Embodiment 2

[0026] Example 2: After the fresh medicinal chrysanthemum enters the automatic de-enzyme drying machine, it is first de-enzymed at a high temperature of 110°C for 45 seconds. At this time, part of the volatile oil with a high boiling point will be lost with water vapor, because the water content of this part of water-oil mixed steam is relatively high. Large, the overall volatile oil content is low, and it is not suitable for recovery as volatile oil due to economic considerations. Therefore, it can be developed into primary products such as chrysanthemum dew after passing through a circulating condensing device, cooling and recycling, and simple processing. In order to ensure quality, chrysanthemum The recovered amount of dew should not exceed the fresh weight of chrysanthemums. Next, the chrysanthemum is automatically transferred to a dryer for drying, the drying temperature is controlled at 70° C., and the drying time is 6.5 hours. According to the experience in the process...

Embodiment 3

[0028] Example 3: The basic steps are the same as those in Example 2, the difference is: the temperature for killing greens is controlled at 105° C., and the time for killing greens is 55 seconds; the drying temperature is 72° C., and the drying time is 7.5 hours. The water-oil mixed steam generated within 3-5 hours of drying time is collected and subjected to subsequent treatment to separate and obtain volatile oil, which has high unsaturation and excellent quality.

Abstract

The invention discloses a method for recovering byproducts generated in processing process of medicinal chrysanthemum flower. The method comprises the following steps: deactivating enzymes of fresh medicinal chrysanthemum flowers at 100-110DEG C for 45-55 s, and drying medicinal chrysanthemum flowers at 70-75DEG C for 6.5-7.5 h, wherein water-oil mixed vapor generated in 2-6 h of drying is collected and fed into a condenser, a cooling tower and an oil-water separator in sequence, and after separation in the oil-water separator, the obtained upper oil layer is volatile oil, and the lower water layer is aromatic water. The method disclosed by the invention can reutilize the waste generated during processing process of chrysanthemum flowers, and extract volatile oil and other byproducts from the waste, does not need additional chrysanthemum flower raw material and heat energy, and can change waste into valuables and reduce waste and improve efficiency. The obtained volatile oil has good quality, and has good economic benefits and social benefits.

Description

technical field [0001] The invention relates to a processing technology of medicinal chrysanthemum, in particular to a recovery method of by-products such as volatile oil, aromatic water and chrysanthemum dew produced during the processing of medicinal chrysanthemum. Background technique [0002] Chrysanthemum is the dry flower head of chrysanthemum (Chrysanthemum morifolium Ramat.), which is not only a traditional Chinese medicine commonly used in my country, but also one of the important export medicinal materials. Chrysanthemum chrysanthemum extract can enhance capillary resistance, reduce blood fat and cholesterol content, improve myocardial nutrition, anti-inflammation, and at the same time remove active oxygen free radicals. effect. Volatile oil, also known as essential oil, is one of the main active extracts of chrysanthemum, a general term for a class of volatile oily liquids that exist in plants and can be distilled out with water vapor. Modern studies have shown ...
