The more you chew the betel nut, the more vigorous you are. This mouth comes out and the other mouth comes in. Make friends and make friends on the garden platform to avoid the plague and appetite and relieve the oiliness. "This is a folk song circulated on the streets and alleys of Xiangtan, which vividly reflects the indissoluble bond between betel nut, Xiangtan people and Xiangtan food culture. Betel nut, as a food, has taken root in Xiangtan for more than 300 years. According to the "Xiangtan City Chronicles": In the first month of 1650 (the sixth year of Shunzhi), the Qing soldiers slaughtered the city for nine days in Xiangtan. The population of the county seat was tens of thousands. The remaining households were less than 20 or 30, and the population was dissatisfied. There was a surname. Cheng's Anhui merchants had an old monk chewing betel nuts to avoid the epidemic and harvest the corpses, and the habit of chewing betel nuts has continued since then.

In 1779 (forty-fourth year of Emperor Qianlong), the Xiangtan epidemic caused the residents of Xiangtan city to suffer from bloating disease. The county magistrate Bai Jing divided the medicinal betel nut into patients and chewed them. Also chew it, and become a habit. As a result, Xiangtan betel nut has gradually developed. With the development of Xiangtan betel nut, betel nut culture also came into being. In some places, folk rituals such as ancient flower operas, "praising the land" and wedding celebrations all have betel nut praises, such as "Tanzhou Zhuzhi Ci" writes: " The romantic drama is about Yang, beautiful and elegant; a string of beaded throat songs turn around, and some people throw betel nuts in the audience.” It vividly outlines the close relationship between Xiangtan betel nuts and local culture and art. This also precisely shows that Xiangtan betel nut culture is the product of the development of Xiangtan betel nut. This reflects from one aspect that economic development gestates the emergence of superstructures (culture and art). In turn, culture and art promote economic take-off. This is a universal law. Of course, from the perspective of the whole betel nut culture, a beautiful and rich folk song "Picking Betel Nuts" expresses the people's special feelings for betel nuts in the form of art.

Using dehumidification drying equipment, a single-factor drying experiment and a multi-stage cyclic drying experiment were designed for the two main influencing factors of temperature and relative humidity in the batch drying of brine betel nut, and the secondary drying characteristics of betel nut were studied. The moisture content of the dried product was tested. , Comprehensive evaluation of brine drying uniformity, color, taste, etc., and compare it with traditional warehouse natural dry products. The single factor experiment shows that the drying of viscous materials should maintain a higher relative humidity and a shorter high temperature drying time. Moreover, it is difficult to dry viscous brine with a certain thickness at a single temperature and relative humidity; the results of multi-stage cyclic drying experiments show that the use of normal temperature and high humidity slow su can better promote the taste of betel nut, and a short time of high temperature and low humidity drying can quickly achieve dehumidification. The purpose is to prevent serious encrustation on the brine surface, and to obtain a better process for the slow-relief stage as the parameters 25℃, 80%, and the drying stage to 30°C, 60%. The drying method of slow-drying-slow-supplying is adopted to ensure that the first and last stages are The slow-supply section, and the slow-supply drying ratio is 3:1. Compared with the traditional shade drying, the product has a stronger aroma, shorter drying time, and improved production efficiency. The obtained brine drying process is of great significance to production practice and the realization of automated production.

The above is the sharing of the batch automatic drying of brine betel nut introduced by Nesta, so please feel free to contact us for more information about the drying of brine betel nut.
