The food waste processor is very close to you
Environmental protection is inseparable from the efforts of everyone. From now on, start from the family, from the most inseparable kitchen to start, use the small electrical appliances that help environmental protection.
On March 1, the country's first local regulation to regulate waste treatment in the form of legislation was officially implemented. Similar to the similar, "Shanghai municipal household garbage classification equipment configuration guidance (trial)" also comes out.
The former made it clear that "the city encourages the listing of pure vegetables, and advocates the standard kitchen waste disposal equipment for living quarters and households." The latter also encourages "in the area where the regional sewage pipeline is qualified, the newly constructed all-in-one housing should be equipped with the kitchen waste (wet garbage) crusher. Other eligible housing, while encouraging the installation of kitchen peel (wet garbage) crusher.
The "kitchen waste disposal unit" and "kitchen waste disposal crusher" mentioned in the two regulations have a single name - the food waste processor. This is a small household appliance that is installed at the bottom of the kitchen sink and is connected to the drain, grinding the food scraps into tiny particles and into the drain with water.
Analysts noted that the promotion of such products was explicitly encouraged, mainly from the perspective of total volume and recyclable use. According to statistics, the annual stock of domestic garbage in China is more than 6 billion tons, and it grows at a rate of more than 10% a year. In the current life garbage composition, kitchen waste accounts for nearly 60 percent. If the kitchen waste is sorting out, will the composting treatment or into sewage treatment plant, the organic matter through recycling become fertilizer or biogas, can get rid of more than 90% of kitchen waste, otherwise need to be done, together with other garbage incineration or landfill.
It can be seen that kitchen waste is the key to realize the reduction, resource and innocuity of living waste. The food waste processor can effectively alleviate this problem from source.
How does the food garbage processor work
Use "small body wise" to describe food garbage handlers as appropriate. In fact, its principle and structure are not complicated, through the motor drive knife disk, use centrifugal force to smash the food waste in the cavity into the back of the drain. The pulverized cavity has a filtration effect and automatically intercepts the food solids. The knife disc has two or four 360-degree turnround and no sharp edge.
In the treatment mode, the food waste processor can be divided into: crushing type and drying type. The former USES the food waste to be ground, crushed and mixed with water into the liquid form directly into the drain; The latter separated the food waste water from the solid state and drained the water from the water basin, leaving the solid material to be condensed into block, which is convenient for storage and disposal.
According to motor type, food waste processor can be divided into: dc type and ac type. The speed and torque of the dc motor are higher, the grinding speed and the grinding efficiency are greater than the ac type, but the noise is slightly larger when idling, and it is often unstable due to the change of carbon brush. The ac idling speed is low, the processing efficiency is low, because the torque is larger and can smash hard food waste, but the whole machine cost is higher. The low incidence of ac faults, longer life, low noise and convenient maintenance, many manufacturers are gradually transitioning from dc to ac.
According to the principle of grinding, the food waste processor can be divided into two stages: secondary grinding, three-stage grinding and four-level grinding. Secondary grinding is when food waste into the grinding chamber, the knife dish on a 360 - degree rotating impact grinding head, grinding particles after did not directly into the sewer, but because of centrifugal force and the role of the cutting tools in cutting wheel grinding edge; Tertiary grinding is the secondary grinding the food waste in the process of decline, flat space between the grinding disc and stainless steel lining to further grinding of food waste, the fiber and bony treatment effect is better; The four - level grinding is based on the three - level grinding, and then increases the primary plane grinding, which can make the food waste reach the slurry state, which is more conducive to the discharge and drainage of the sewer.
Does the food garbage processor work for the family
At present, most consumers are unfamiliar with food waste processors, mainly because they do not know the product itself.
In fact, many families had similar experience: food scraps in a plastic bag in a corner, to be convenient when out of the outdoor, but there are too many, fashion and garbage bags thin, easily damaged, residual soup easy leakage and; Or because it has been shelved for a long time, the garbage can smell. In addition, choosing vegetables, washing dishes, accidentally falling into the water leakage of the vegetable leaves are easy to clog the sewer, cleaning up very troublesome.
A food waste processor comes in handy. Its product features let food residues need not be mixed with other life rubbish, and the side wash dish, brush bowl side direct processing, clean sanitation, save time and effort.
However, there are still many consumers who have doubts about it, pouring food waste into the sewer and not clogging it. That Emerson love comfortable easy jian-min Chen, general manager explained that in 2010, Emerson love comfortable easy to joint the national engineering research center of tongji university city pollution control was carried out by a year of market research. Instead of clogging the sewer, the assembly of food waste processors can help unclog and clean up the grease, the results show.
Wei pan Ming, director of the Beijing sanitation research institute, has also said that the addition of kitchen waste disposing machines will not clog sewers, but can flush the pipes and drain pipes. After treatment, kitchen waste not only meets the requirements of sewage treatment plants, but also can increase the biodegradable material, which is beneficial to sewage treatment. However, the water content decreased obviously after the garbage was mixed in, and the calorific value increased obviously, which was helpful for incineration.
It is also true that the cost of food waste processors is not high. Generally, the input power of the food waste processor is between 350 and 750 watts, and the water consumption is 5 litres per day, and the service life of the mature manufacturing process can reach 12 to 15 years. The cost of all the usage adds up to 100 yuan per year.
Product features, however, decided to food waste processor inevitably produce noise at work, but by adjusting the inner structure, improve the grinding speed, noise can be controlled in a reasonable range. The relevant standards have also been made clear in the noise limit.
What are the domestic market conditions for food waste processors
The food waste processor is an imported product which is popularized in developed countries in Europe and the United States. In the United States, food waste processor in 2009 was listed in national green building standards, by the NAHB (the national association of home builders) issued by the us green building standards, explicitly pointed out that, in the main under the kitchen sink at least installing a food waste processor. Currently, 80% of new U.S. homes have food waste processors.
In the 1990s, household food waste processors entered the country, and in the first-tier cities with higher living standards, such as Beijing, Shanghai and guangzhou began to cultivate the market and gradually promote it. Then some foreign manufacturers set up production bases in China to localize their products, thus reducing the cost of all aspects to increase the competitiveness of the market and to be ready to play a big role in the Chinese market. But the domestic market response is still fairly flat, and the urban family is not more than 10 percent. In 2003, the use of food waste processors in Beijing, Shanghai and guangzhou was only 4.3 percent, 3.8 percent and 3.5 percent, respectively.
In recent years, foreign manufacturers have promoted the food waste processor in China through cooperation with local government departments. For example, in January 2011, hebei caofeidian eco-city was funded by the government department, and the first batch of nearly 800 homes purchased food waste processors. Food waste processor at the same time, also a brand with the Shanghai pudong new area, the selection of pilot area in pudong new area of more than 2000 residents of neighborhood garbage classification, residents by the pudong new area government subsidies to install food waste processor.
Standards and certification specify which performance
Although the food waste processor has a long way to go in domestic popularization, the relevant standards certification system has taken the lead and paved the way for industry norms.
December 30, 2008, GB/T 22802-2008, the national standard issued by the household waste food processor, and implemented on 1 September 2009. The implementation also includes the completion of the revised GB 4706.49-2008 special requirements for the safe abandonment food processor for household and similar appliances. The former stipulates clearly the rated voltage not exceeding 250 v of food waste processor after grinding rate of grinding, grinding speed, percentage of fineness of food waste, noise, vibration and other performance index and test methods. Among them, the experimental load was divided into two kinds: bone and mixed type. Standard according to the domestic sewage system construction proposed the concept of the fineness of food waste, by the panel test many times and finally determine the experimental method, embodies the performance index and percentage. In addition to equipment processing capacity test method and determine the limit, also according to the installation of family environment and the appliance of scalability on the product structure regulation, and connecting with the domestic use of the environment request the installation and use. And environmental temperature 0 ~ 40 ℃ and relative humidity below 95% (when the temperature is 25 ℃) of the laboratory test condition, is also the result of the simulation apparatus as far as possible the actual working environment. In addition, the equipment was classified according to the ac, continuous and intermittent loading, and the equipment was named according to QB/T3901.
In order to better recommend high-quality products to consumers, the Beijing center for light and light certification authority issued the gk38-a /0 "implementation rules for the performance certification of electrical appliances" on May 31, 2011. According to the rules, the Chinese electrical appliances research institute and Beijing united certification center jointly launched A + grade certification of food waste processor of food waste processor 5 to make A provision capacity index, obtained the certification of food waste processor performance is superior to the standards set by the standard for household food waste processor threshold.
About food waste processors
1927 the world's first abandoned food processor was born in Wisconsin.
In 1955, the state of Michigan Detroit building rules and regulations: built after January 1, 1956, who design, install and use can lead to the food waste city buildings, must be equipped with prior approval of food waste treatment equipment, if you use the building was not equipped with such equipment will be illegal.
In 1985, the state government of the United States added recognition and affirmation of the widespread use of abandoned food processors in the city, and the use of discarded food processors into large-scale use.
In 1999, New York City government officials assessed the environmental impact of the garbage processor project, and concluded that the large-scale installation of food waste processors was conducive to the environment.
In 2001, China construction ministry listed the food waste processor as the key development project and recommended supporting products for residential renovation.
