Problems solved by technology

The drying temperature of this method is high, the energy consumption is large, and the quality of the chrysanthemum is affected, and the chrysanthemum is easy to lose petals and loose petals during drying.
[0006] Most of the drying methods used in industrial production are difficult to achieve uniform drying under the premise of ensuring product quality and energy saving; secondly, it is not easy to monitor in real time during the drying process, and there are interferences from other substances, and even It is pollution, which affects the quality of edible flowers and makes it difficult to meet organic standards

Embodiment 1

[0035] A kind of drying method of organic edible flowers of the present embodiment comprises the following steps:

[0036] 1) The picked organic chrysanthemums are graded and selected, and then arranged manually;

[0037] 2) Heat pump drying: It is carried out in three stages. The first stage: slow drying at low temperature and high humidity for 1 hour, to preserve the quality of the organic chrysanthemum itself to the greatest extent; the second stage: gradually raising the temperature and lowering the humidity and drying for 8 hours, while ensuring product quality. At the same time, speed up the drying rate; the third stage: drying at high temperature and low humidity for 3 hours to maximize the drying rate and save energy; the drying parameters of the heat pump are shown in Table 5;

Abstract

A drying method of an organic edible flower comprises the following steps: 1) grading and selecting picked organic chrysanthemum, then artificially placing a dish; 2) drying with a heat pump, to be more specific, the moisture content of a product is 9.5%-11.5% by selection of heat pump type drying for 9-13h, the heat pump type drying is divided into three stages comprising low temperature high humidity slow drying for 1-2h in the first stage being, gradual warming dehumidifying drying for 5-8 h in the second stage and high temperature low humidity drying for 3-4h in the third stage; 3) again grading and selecting the dried organic chrysanthemum according to quality, and filling nitrogen to pack each piece of organic chrysanthemum. The drying method is environmentally friendly and efficient, zero-pollution to a dry matter and the environment, and simple in operation and control process, can work continuously, is high in industrial production efficiency, avoids petal scattering and falling phenomena of organic edible flowers, improves the appearance aroma and taste of the prepared flower, and ensures the nutritional effects of a product, and the product is high in quality and long in storage time.

Description

technical field [0001] The invention relates to a method for drying flowers, in particular to a method for drying organic edible flowers. Background technique [0002] At present, the drying methods of organic edible flowers mainly include steam scalding, hot air drying and baking. Among them, the steam scalding method has great limitations in industrialized production, and consumes a lot of energy. Hot air drying is relatively safe, but it is difficult to accurately control the temperature, humidity, and moisture during the drying process. [0003] CN 103518904 A discloses a method for processing chrysanthemums. In the method, fresh chrysanthemums are picked first, impurities and unqualified chrysanthemums are screened out, and the first round of drying is carried out at a temperature of 45-55°C. The drying time is 9-11 hours. After drying, spread the chrysanthemums in a cool and ventilated place indoors for 24 hours, and then carry out a second round of drying at a tempe...
