How to Dry Yam/Dehydrate Yam in a Dehydrator
Introduction to yam：
Yam tubers are long cylindrical and grow vertically. The stem is usually purplish red. The seed is born in the middle of the axis of each chamber. Flowering from June to September, fruiting from July to November.
Yam drying process：
After peeling the yam, cut it into yam of uniform thickness and size. After water treatment, drain the water and place it on the stainless steel material frame. Be careful not to pile up, and leave a certain amount between the slices. Clearance. Start the heat pump dryer, set the drying temperature to 50°C in the first paragraph of parameters, and the time is 0.5-1 .5 hours. After the previous heating up, the dryer also started a small amount of dehumidification work, and then when the temperature parameter is set in the range of 40°C- 50°C, the yam in the drying room is in a state of low temperature and high humidity, and water vapor begins to form on the surface of the yam. , The condensation becomes water and drains out of the drying room. At this stage, the drying time is 3 hours.On the basis of the above, continue to increase the temperature by 10°C, and set the temperature parameter in the range of 50°C- 60°C. As the temperature continues to rise, the yam is in a state of medium temperature and humidity. At this time, the continuous temperature and circulating wind The heat is evenly sent to all corners of the drying room, and the mountain pills continue to evaporate water vapor and be taken away by the dehumidification system.
As the temperature rises and the water vapor is discharged, the humidity of the mountain pill is getting lower and lower. When the temperature parameter is finally set at 60°C -70°C, the moisture removal strength will increase until the mountain pill is dried to a moisture content of about 10%, it takes about 6 hours. At this time, the yam tablet has been dried, and it is broken by hand, and the outside and inside are evenly dried.
Recommendation of yam dryer/drying machine
Commercial 100-3000kg/h large amount of dehydration wide application and easy operation
Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.
Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
