Problems solved by technology

[0006] At present, the preservation method of yellow flowers used in production is mainly drying, and a small amount is pickled with sodium metabisulfite for large pond storage, but the problem of residual sulfur dioxide affects the safety of yellow flowers
The production technology of yellow flower drying in industrial application is mainly hot air drying; among them, the heating source of hot air drying is mostly a boiler, and there is also electric heating, but the energy consumption is high and the drying time is long; some researchers use freeze drying, although the quality of yellow flower products is good, But the investment cost and operation cost are high, so it is difficult to popularize and apply
Some researchers use microwave-hot air, infrared-hot air and other combined drying processes, but in the actual application process, there are still problems of uneven drying, high energy consumption, and uneven color

Abstract

The invention discloses a day lily infrared heat pump combined drying technology. The technology includes the following steps of S1, picking, cleaning and airing fresh day lily; S2, filling a processing bag with the day lily; S3, executing fixation action on the day lily in the processing bag; S5, stopping the fixation treatment, and filling a material plate with the day lily; S6, drying the day lily in the material plate through a heat pump; S6, conducting far infrared fixation treatment on the day lily in the drying treatment process of the heat pump; S7, stopping the radiation treatment ofa far infrared heat source and the drying treatment of the heat pump; S8, taking out the day lily, evenly spreading and airing the day lily, and conducting cooling until the room temperature is reached; S9, conducting vacuum bagging and storing on the aired day lily. The day lily drying efficiency is improved, the efficient low-consumption drying of the day lily is truly realized, coking and colorchanging caused by high-temperature drying of part of flower bodies are avoided, the loss of vitamins and other nutrients in flower buds is avoided, and the non-enzymatic browning of the day lily isreduced. The day lily processing effect is good, and the nutritional value is high.

Description

technical field [0001] The invention relates to the field, in particular to an infrared heat pump combined drying technology for day lily. Background technique [0002] my country is one of the main producing countries of yellow flowers. Yellow flowers are cultivated on a large scale in Sichuan, Hunan, Zhejiang and other places. less. [0003] Yellow flowers have the functions of invigorating the stomach, unblocking the breast, and enriching the blood. Lactating women who have insufficient milk secretion can eat it, which can play the role of unblocking the breast and producing milk; because the day lily is rich in lecithin, this substance is used by many cells in the body. In particular, the composition of brain cells plays an important role in enhancing and improving brain function. At the same time, it can remove deposits in arteries and has special effects on symptoms such as inattention, memory loss, and cerebral artery blockage. "Brain food". According to another stu...
