Earlier, the author saw a message that a restaurant owner in Germany tried to sell crayfish. As a result, one day's sales of ten pounds sighed that the business was good enough. The bottom of the net friend silently said that it was just me alone. Comparing to the gloomy lobster sales, the crawfish season in all parts of the country was in a state of war: A restaurant owner from Hubei Qianjiang stated that the two restaurants can sell 12 tons of crayfish in one day; a reporter in Nanjing estimates roughly that day Killed 60 tons of crayfish. However, when the crawfish industry is booming, the issue of shrimp shells brought out can not be ignored.
Shrimp Shell Besieged City Problem Solving
Although the number of crayfish eliminated is impressive, people who have experienced eating lobsters have the feeling that a crayfish can eat it. The lobster meat eaten is only a short segment, occupying nearly 80 percent of the entire crayfish shell, head, and tail. Some of these can only be discarded. In this way, most of the cities in China face the situation of shrimp siege.
In fact, research on the use of shrimp husks had a long history of corresponding research. In the 1990s, there were companies that further processed shrimp hulls to refine chitin and deepen the industrial chain. However, as crayfish became a national cuisine, catering value As the water goes up, the use of shrimp shells becomes more difficult.
First of all, because different places have different eating habits, like Zhejiang, Jiangsu and other places, crayfish are commonly used as food when eating shrimp. The shrimp shell is removed by the consumer. At this time, the shrimp shell is often mixed with napkins. Beer bottles, leftovers and other miscellaneous items, if companies recycle these shrimp shells, they also need to develop sorting equipment to sort different types of garbage. Secondly, the lobster shells that are discarded after this meal need to be recovered in time, otherwise they will be recovered in time. The odor of the lobster shell will be accompanied by juice after the meal. The leak during transportation will easily pollute the urban environment. Finally, the production method of extracting chitin from the shrimp shell is odor, and there are many wastes. It is difficult to meet environmental standards. .
Upgrade production and processing equipment to seek a new outlet for deep processing of shrimp shells
I still remember that the old crayfish was popular because of its ability to liberate the 'social attributes' from mobile phones. Recently, however, the author has seen many news reports that the restaurant is equipped with part-time peeling shrimps. Consumers who want to use their hands to play mobile phones have a clear idea. From this it is not difficult to see the tendency of crayfish to provide shell-free food and beverages in the future. Earlier, there was a company in China that developed shelling equipment for crayfish shells to achieve Crusting large numbers of crayfish quickly. If the equipment is able to penetrate deep inside the catering, then the clean shrimp shell will also become easy to collect.
In response to the problem of dripping of scorpions that may occur during the transportation of shrimp hulls, some companies started with the renovation of kitchen waste recycling vehicles. By arranging diversion-type sewers for transport vehicles, the leaked sewage was drained into dedicated sewer collection tanks. Makes kitchen wastes no longer 'runs' when transported, reducing people’s dislike during shrimp collection.
In addition, as mentioned above, shrimp shell deep-processing technology has already emerged, but in the current production process does not meet the current requirements for environmental protection, clean production, need to improve the technology, equipment, etc. It is reported that in the deep processing of shrimp shell, The use of the boiler is inevitable, but if the boiler directly discharges the exhaust gas, it will cause the environmental protection index to fail to reach the standard. Therefore, it is necessary to connect the flue gas treatment equipment outside the boiler to purify the smoke.
The crawfish industry is hot and self-evident. In the process, how can the shrimp shell, which is a by-product of the kitchen waste, be turned into kitchen waste resources and re-serving the society is inevitable in the sustainable development of the crayfish industry. One problem. Fortunately, many companies in China have long been committed to the study of the value of crayfish shrimp shells. Currently, there are more than ten kinds of shrimp shell deep processing products produced by enterprises, which greatly extends the crayfish industrial chain and contributes to ecological environmental protection.
