Introduction to Zongye：

  There are many varieties of Zongye, which are generally made from reed leaves and Zongye, which are indispensable materials for making zongzi. Zongye generally have a large amount of chlorophyll and a variety of amino acids that are beneficial to the human body. Its special antiseptic effect is also one of the reasons why zongzi is easy to preserve. The smell is fragrant, and it smells like returning to nature. It can be used not only to wrap rice dumplings, but also to package other foods and table decorations and food foils, and can also be used to make hats, handicrafts, etc.

Zongye drying process：

  The drying of Zongye is also an intensive drying. The upper and lower circulation system with top air outlet cannot achieve uniform drying of the Zongye in the drying room. Therefore, the side 360 circulation system with side air outlet is more suitable. The dry system has certain requirements for the placement of the Zongye. The hot air needs to pass through the gap between the Zongye and return to the tail air return. Therefore, the placement of the Zongye needs to leave a gap in the air path, which is about 5-10 cm.
  According to a 12P host with a 6-meter-long, 4-meter-wide, and 2.2-meter-high drying room, 2000 kg of fresh Zongye can be placed at a time. The total time is 24 hours, which is divided into three sections to complete. The first stage is 3 hours, the temperature is 60 ℃, and the mode is dried. The second stage is 10 hours, the temperature is 65°C, the relative humidity in the drying room is 35%, and the mode is drying + dehumidification. The third stage is 68℃, the relative humidity in the drying room is 18%, and the time is 11 hours. The moisture content of the dried Zongye is less than 13%. When the brown leaves are dry, they will be dark green, grayish black or yellowish gray, and will not be cyan. The moisture content of the dried Zongye is less than 13%, and it can be cooled down naturally.
  The most difficult part of the Zongye to dry is the stem part of the bundle. If this part is not so thick, the drying time will be shortened. When drying Zongye, do not block the exhaust air of the axial flow fan, otherwise the heat generated by the host cannot be blown out normally, which will easily cause the compressor to protect the high pressure.

Recommendation of Zongye 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.
