Lily is a plant in Liliaceae, including dry fleshy scales of curl, lily and fine leaf lily. It is useful for moistening lung to arrest cough, lily is the ministry of Health first announced the same food. There is medicine lily, rice lily, vegetable lily, longya lily, tiger melon lily, among which longya lily contains rich alkaloids, protein, mineral elements, is a treasure in food. Therefore, the lily dryer is becoming one of the essential equipment in the lily processing.
The new steam heating lily dryer is put into production comply with requirements for lily dryer:
Material requirements: Pour the drained lily slices into the equipment, and spread the product evenly on the equipment mesh belt. After spreading evenly (avoid overlapping lily pieces), lily in the drying equipment for hot air circulation drying.
Drying requirements: the oven temperature setting should be set to be controlled at 55~70℃, and the initial temperature is usually set at about 55℃. The lily piece is evenly heated and expel some water, and then gradually raise the temperature, and gradually drain wet.
The material turn: material drying early need to turn 1 times an hour, so that the material moisture effective evaporation, when the drying temperature rises to 65℃, to constant temperature drying and effective dehumidification, material need 2 hours turn once, these can all be achieved through the control system, when dry to lily water content is about 10%, lily becomes hard and with a wax feeling, hand fold lily fracture brittle sound, namely complete the drying.
Therefore, the humidity and moisture content of the material itself has an important influence on drying, in the process of drying material, according to the initial moisture content, dehydration rate, water loss, drying data to drying system design and determine the host selection, scientific design can better, faster, more efficient to achieve the purpose of material drying, drying the quality of finished products will be guaranteed.
