Method and equipment for drying day lily degradation chlorophyll

Abstract

The invention discloses a method and equipment for drying day lily degradation chlorophyll. The drying method comprises the steps of setting temperature and humidity parameters, placing day lily, carrying out blanching operation, carrying out hot air drying operation and storing operation; the drying equipment comprises a box body, an electric cabinet, a moisture removal opening, a ventilation opening and a fan motor; and supporting plates are symmetrically arranged in the box body, the right supporting plate divides the box body into a left space and a right space, a material tray is arrangedin the middle of each supporting plate, an infrared light pipe is arranged between the material trays, a water basin is arranged on the uppermost material tray, and an ultrasonic atomizing head is arranged in the water basin. The drying method is reasonable in the design, the drying equipment is convenient to use, the temperature and the humidity inside the box body can be controlled, the dryingspeed of the day lily is controlled, and the drying quality of the day lily is improved; the day lily is subjected to blanching and fixation through high-temperature satiety and steam; and the multiple layer of infrared tubes are adopted for infrared radiation heating, the generated heat is uniformly and comprehensively distributed, and the production and processing requirements of large-batch daylily are met.

Description

technical field [0001] The invention relates to the technical field of day lily drying, in particular to a drying method and equipment for day lily degrading chlorophyll. Background technique [0002] In the vegetable processing industry, there is an important drying and finishing process, which usually needs to be processed in a drying oven. Taking day lily as an example, day lily, also known as day lily, commonly known as day lily, is a perennial herb of the Liliaceae Hemerocallis genus, and its edible part is a flower bud. It is a characteristic vegetable in my country. Day lily has high nutritional value, contains carbohydrates, proteins, vitamins, inorganic salts and a variety of amino acids necessary for the human body. It tastes delicious and is deeply loved by consumers. Processing day lily into dried vegetables is the main form of day lily processing. The common methods of dried vegetable processing are sun drying and mechanical drying. [0003] During the sun-dr...
