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 method for drying organic edible flowers, comprising the following steps: 1) Grading and selecting picked organic chrysanthemums, and then placing them manually; 2) Heat pump drying: use heat pump drying for 9 to 13 hours, so that the water content of the product It is 9.5%~11.5%, divided into three stages, the first stage: slow drying at low temperature and high humidity for 1~2 hours; the second stage: gradually increasing temperature and reducing humidity and drying for 5~8 hours; 4h; 3) The dried organic chrysanthemums are graded and selected again according to the quality, and packed in separate flowers with nitrogen filling. The drying method of the present invention is environmentally friendly and highly efficient, and has zero pollution to dry matter and the environment; the operation and control process is simple, it can work continuously, and the industrial production efficiency is high; The appearance, fragrance and taste after processing ensure the nutritional efficacy of the product, the product is of high quality and has a long 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] CN103518904A discloses a method for processing chrysanthemums. In this method, fresh chrysanthemums are picked first, impurities and unqualified chrysanthemums are screened out, and then the first round of drying is carried out at a temperature of 45-55°C. The drying time is 9-11 hours. Finally, spread the chrysanthemums in a cool and ventilated place indoors for 24 hours, then carry out a second round of drying at a temperatur...
