In the industrial production process of food, a large amount of water and electricity are needed, and the discharge of waste water, waste gas and solid residue is also inevitable. With the launch of environmental protection slogans, food companies in all parts of China have been investigated and punished for failing to meet environmental protection related indicators. A winery in Pubei, Guangxi, exudes an unbearable smell. After investigation, the fermentation slag waste was not treated in time; a vegetable pickled vegetable company in Jiangsu Guangling continued to grow and develop. The original environmental protection facilities could not meet the sewage demand but were not updated. The wastewater discharge from Guangdong Chaozhou Liangguojia Workshop has been questioned by the masses... It is not difficult to see that food production in various places frequently touches the environmental protection high-voltage line. There are three reasons for food companies to produce environmental problems. First, energy consumption in the food production process is too high, and waste disposal is too difficult. For the production of dehydrated garlic slices, it is reported that the production of a dehydrated garlic slice requires three or forty times of water, which contains a large amount of garlic polysaccharide, alliin and other ingredients. It is difficult to achieve the standard discharge treatment of wastewater. . Second, environmental protection equipment cannot keep up with the current production capacity. The disposal of waste requires money, equipment, etc. These costs are directly included in the cost of food production, thereby reducing corporate profits. Under this circumstance, many food companies are not satisfied with environmental protection facilities, and the purchase of environmentally friendly processing equipment cannot keep up with the production capacity of food. There are also enterprises that increase production capacity during the continuous development process, but have not upgraded and upgraded environmental protection equipment. Third, the idea of ​​environmentally friendly production of enterprises is not enough. Only economic efficiency is used as the criterion for production, and all behaviors that increase the cost of food production are minimized. Under the guidance of this kind of thinking, many companies have adopted inappropriate methods to avoid environmental protection review in the food production process. Such as changing the drainage port, the implementation of "nocturnal night out" production. Food industry environmental protection problem needs to be multi-pronged Judging from the smuggling and leakage of food enterprises examined by various localities, the methods used by these food companies to produce and change the drainage outlets at night have been rectified and required to be rectified. It is obvious that such evasive emissions are not a long-term solution. . To solve the environmental problems of food companies, we need to improve the performance of equipment, enhance the processing capacity of environmental protection equipment, and improve the environmental awareness of enterprises. First of all, improving the performance of food production equipment and upgrading food production processes can effectively achieve environmental protection. Statistics show that the amount of water consumed in the production of canned food in China is two to three times that of the United States, which is closely related to the performance of food production equipment and food production technology. Some enterprises have found that the water consumption is reduced by more than 15% compared with domestic equipment after the introduction of foreign drinking water production lines. It is conceivable that energy conservation and environmental protection in the field of food machinery and equipment is promising. At present, most food machinery equipment manufacturers in China have noticed the national environmental protection trend, and the food machinery equipment developed has achieved energy conservation and environmental protection to a certain extent. A food machinery enterprise in Ningbo has developed a multi-function spray sterilization machine. The device has an automatic flipping and automatic reset function. During the sterilization process of the bottle contents, the high temperature can be transferred to the bottle mouth and the bottle cap without other The heat source achieves full sterilization inside the bottle. Secondly, enhancing the processing capacity of environmental protection equipment is also an important means to achieve environmental protection. Foods such as pickles that produce large amounts of waste water need to be equipped with corresponding sewage treatment facilities for production. It is reported that Jiangsu Guangling has such a pickle enterprise, and expands its sewage treatment capacity to 1,000 tons by purchasing environmental protection processing equipment. On this basis, online monitoring equipment is installed to facilitate real-time supervision by the Environmental Protection Agency. Finally, it is extremely important to improve the environmental awareness of enterprises, because the end users of food machinery and equipment and environmental protection equipment are food enterprises. After the development of relevant environmental protection equipment, food enterprises must be used to maximize their benefits. From the perspective of market prices, environmental protection equipment is more expensive than traditional equipment because it invests more research and development. However, the use of energy-saving and environmentally friendly equipment will save energy costs and waste disposal costs for enterprises in the food production process, and can also greatly reduce the risk of rectification of enterprises by environmental protection departments. Nowadays, environmental protection departments at all levels have stepped up environmental protection review and required enterprises to carry out rectification in the production process in accordance with various laws and regulations. In fact, it is also possible to add some “flexibility†in this process, such as awarding companies that meet environmental protection requirements, achieving policy tilt, and subsidizing. This kind of reward will guide more food companies to think about environmental issues in the production process to a certain extent. As an important civil production industry in China, the food industry needs to be supervised by all walks of life in the production process. Energy conservation and environmental protection have become an inevitable problem for enterprises. It is also necessary for China's food machinery equipment manufacturers to accelerate the research and development of environmentally friendly and energy-saving equipment.
