Shandong commercial newspaper probationer reporter Wang Yanbin
the province will enter the late autumn season, the temperature is getting lower and lower. There are more and more roasted sweet potatoes on the street, and many people like to eat a hot potato in the cold weather, but most people don't care about the oven used to roast sweet potatoes on the street. According to a press survey, many of the stoves used to bake sweet potatoes on the streets are transformed by oil tanks, some of which have been used for chemical products such as gasoline.

the reporter noticed that the potato stall on the street is mostly distributed around universities and in residential areas. There are three stalls selling roasted gours near the West Campus of the University of Jinan. There is a stall on the west gate of the school on the opposite side of the west gate of the school. The vendor has just put out a roast oven in the last few days, with a height of about one meter and half a meter in diameter. Inside is a blue iron bucket. Most of the iron barrel is wrapped in a layer of silver iron. The blue iron bucket on the bottom is rusty, and the outer iron hole has been smoked into black. At noon, many people came to buy roasted sweet potatoes. "My iron bucket has been used for ten years, and it is very strong." The owner said. When the reporter inquired about the previous use of the barrel, she said, "for oil." When the reporter inquired further about what the oil was, she began to falter.
on the road from the west gate of University of Jinan to the ten road, only seven or eight of the roast paw stall was observed by journalists, and most of them were similar to that of the reporters. Among them, there is a place in the vicinity of Wang Guan Zhuang, which looks like a new stove made of sweet potato pits. The difference is that the iron barrel covered with silver iron is red. There are also a bunch of numbers on the silver sheet, which are telephone numbers. "This year just bought, the address is on the east side of the flyover, they specialize in doing this." The owner said it would cost more than 300 yuan to buy such an oven. "This is an oil barrel, whether it is oil or gasoline, brush clean, and then the fire will be baked, and it must be clean."
the reporter then dialed the telephone number marked on the iron bucket. The man who answered the phone said that the company's address was in the north of the people's mall. A barrel should be 380 yuan. It was processed well. It could be baked directly. Many people recently bought this kind of oven. "The oil barrel for processing is the kind of oil made of cake." The bucket is not the kind of bucket in the chemical plant. "
it is very rare to make the stall of the baked sweet potato with a regular oven in the street, but the reporter has seen a stall near University of Jinan with a special roast sweet potato machine for baking a sweet potato. The owner told the reporter that she was absolutely sanitary, the price was around 1000 yuan, and most of the paw stall on the street was reformed with abandoned oil buckets, the cost was very low, and a waste bucket was about 40 dollars.
for the baked sweet potato furnace reformed with oil buckets, some experts pointed out that after the remolding of the oil barrel, after the high temperature baking, some harmful gases will be slowly volatilized and adsorbed on the epidermis of the sweet potato, thereby endangering the health of the human body. If benzene is found in the residue, it will damage the respiratory tract and nervous system. In addition, roasted sweet potatoes on the street are roasted by burning coal, and will also suffer a certain degree of pollution during baking.
, therefore, remind the general public that when buying baked potatoes, they must be cautious. It is best to buy baked potatoes in regular shops or regular bake places.
