Introduction to green tangerine：

  Green tangerine is processed from immature peel. Its volatile oil and hesperidin content are high. It has the functions of nourishing the stomach, clearing heat and detoxification, resolving phlegm and relieving cough, reducing fat and losing weight, beautifying the skin, resisting arteriosclerosis, anti-aging and sobering alcohol.

Green tangerine processing steps：

  The best position for cutting is 3 mm away from the pedicle, so that the pedicle and the entire citrus fruit are kept intact without damaging the fruit tree. Wash at least 5 times or more. You can use a water gun and then a machine to remove dirt and dust first, and then remove residual substances. During the entire cleaning process, if you encounter incomplete or unhealthy fruits, you must immediately select them to ensure the entire batch. The small green tangerines are clean and have a mellow smell.
  When removing the pulp, pay attention. If the force is heavy, the peel may be damaged. If the force is light, the pulp may remain, resulting in a bad taste. In this step, a small round cap is first opened around the pedicle of the green mandarin orange, and then a skilled worker uses a tool to penetrate the cap to remove the pulp. After the peel and the pulp are separated, the small green tangerine at this time has taken shape, just like a green "small teacup." Next, clean the peel again, one is to remove the impurities in the "small tea cup", and the other is to clean it again to ensure the quality. After cleaning, it can be filled with tea after a little air-drying.

Green tangerine drying process：

  The drying process of small green tangerines (half raw drying and full drying) is to make the orange peel better aged during the low-temperature drying process, to maintain the original fragrance to the greatest extent, and to maintain a stable volatile oil aroma, so that the small Green mandarin and Pu'er tea produce unique aromas and taste more mellow and smooth.
In the drying process, the first thing to consider is the high ambient temperature, so after turning on the air energy heat pump dryer, set the parameters of intelligent temperature and humidity control. In the early stage, keep the temperature at 45°C for 4 hours and control the humidity to 50%. So that the scent of tangerine peel is slowly dissipated into the Pu'er tea.
Next, increase the temperature slowly, and just increase by 5°C on the original basis. The dehumidification is also a slow dehumidification, and the range is preferably reduced by 5%. This dry state is maintained for 3 hours. At this stage, you can smell the aroma of tangerine peel in advance.
At this stage, the temperature can be increased and a large amount of moisture can be removed. The temperature is increased by 10°C on the basis of the above 50°C, the humidity is controlled at 30%, and the drying is 4 hours. This process is more critical. The tangerine peel and Pu'er are integrated. The scent begins to emanate at this stage.
Finally, the temperature is increased by 5°C, that is, 65°C, and the humidity is controlled to 15% until it is dried.

Precautions:
After drying, the whole small green mandarin is about 12 grams, of which Pu'er tea is about 9 grams, and the weight of the orange peel is about 3 grams. This proper combination balances the flavors of the orange peel and the tea to achieve the best taste. The volatile oil content of small green tangerines is high. After drying, a thin layer of white frost will appear on the skin of the tangerine, which is a better sign of the quality and efficacy of small green tangerines.

Recommendation of green tangerine 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.
