The working principle and advantages of kitchen waste treatment equipment

Preface: Food waste refers to kitchen waste generated by the catering industry, households and other units, including food residues, fruit peels, vegetable leaves and other organic matter. Reasonable treatment of food waste can not only reduce environmental pollution, but also realize resource utilization. Food waste treatment equipment converts food waste into organic fertilizer, biomass fuel, etc. through a series of processes, which has high environmental protection and economic value. Food waste treatment equipment is a kind of equipment used to treat food waste generated by residents or the catering industry.

A. The advantages of food waste treatment equipment mainly include:

1. Resource utilization: It can effectively treat food waste and convert it into organic fertilizer and energy gas to realize the resource utilization of garbage.

2. High degree of automation: Simple operation, which can greatly reduce the labor intensity of workers.

3. Retain organic matter: It can retain organic matter in the garbage to the maximum extent and increase the output rate of organic fertilizer.

4. Reduce environmental impact: The decomposition technology of the equipment can completely degrade harmful substances in the garbage and reduce the impact on the environment.

5. Reduce the cost of garbage disposal: The kitchen waste treatment equipment also has the advantages of energy saving, environmental protection, stable operation, and easy operation. It can reduce the cost of garbage disposal, improve the recycling rate of resources, and conform to the concept of sustainable development.

6. Applicable to a variety of scenarios: The kitchen waste treatment equipment is suitable for a variety of scenarios, such as restaurants, hotels, canteens, communities, food processing enterprises, etc. It can efficiently handle leftover food, waste grease and other organic waste, reduce the amount of garbage, reduce environmental pollution, and improve environmental sanitation.

7. Automated operation: It usually adopts an integrated design, with functions such as automatic separation, automatic degreasing and dehydration, wastewater discharge collection, and can be controlled manually or automatically.

Kitchen waste treatment equipment is of great significance in the field of environmental protection and kitchen waste treatment, and is one of the important means to achieve urban garbage classification and resource utilization.

B. Disadvantages of kitchen waste treatment equipment:

1. High manufacturing cost: large one-time investment.

2. High corrosion resistance requirements: Since the main components of the equipment are made of metal materials, they need to have high corrosion resistance.

3. Odor and noise problems: Certain odor and noise may be generated during the garbage disposal process, and corresponding environmental protection measures need to be taken to solve them.

C. The principle of garbage disposal by food waste treatment equipment:

1. Food waste needs to be collected and collected through special garbage bins or other collection equipment. Then the collected food waste needs to be crushed to turn large pieces of garbage into fine particles, which is conducive to subsequent fermentation treatment.

2. Food waste treatment equipment adopts biological fermentation technology, does not need to add chemical agents, and reduces pollution to the environment. Through treatment, food waste can be converted into organic fertilizer, biomass fuel, etc., to achieve resource utilization and reduce the consumption of natural resources.

3. The crushed food waste enters the fermentation tank for fermentation. The heat generated during the fermentation process can increase the temperature, promote the growth of microorganisms, and accelerate the decomposition of garbage. Organic waste undergoes anaerobic fermentation under anaerobic conditions to produce organic gases such as methane, which can be used as biomass fuel. Collect the biogas produced by fermentation, which can be used for power generation, heating and other purposes. 4. After fermentation, the food waste will form solid waste and liquid waste, which needs to be separated from the solid and liquid, and the solid part is used as organic fertilizer. Disinfect the solid waste to ensure that there are no harmful microorganisms remaining, and it can be safely used as organic fertilizer.

5. Finally, the treated food waste is converted into organic fertilizer, biomass fuel, etc. to achieve resource utilization.

D. The role of food waste treatment equipment:

1. The volume of the treated food waste is greatly reduced, which reduces the occupation of the landfill and extends the service life of the landfill.

2. Through fermentation and anaerobic fermentation treatment, the odor generated by food waste can be reduced and the surrounding environment can be improved.

3. Food waste treatment equipment can produce organic gases such as biogas, which can be used as biomass fuel to reduce energy consumption costs.

4. Adopt processes such as microbial high-temperature aerobic fermentation to convert organic waste into resource products such as organic fertilizer or biodiesel raw materials, thereby achieving harmlessness, reduction and resource utilization of garbage.

E. Development trend of food waste treatment equipment: With the improvement of people's environmental awareness and the increase of urban domestic waste treatment pressure, the application prospects of food waste treatment equipment are very broad. In the treatment of urban waste at home and abroad, the market share of food waste treatment equipment has gradually increased. At the same time, with the continuous advancement of technology and the accumulation of application experience, the manufacturing cost of equipment will gradually decrease, and the waste treatment efficiency will also be improved.

PS: Food waste treatment equipment converts food waste into organic fertilizer, biomass fuel, etc. through a series of processes, which has high environmental protection and economic value, and is of great significance to promote garbage classification and resource utilization. With the enhancement of people's environmental awareness, the application prospects of food waste treatment equipment will become more and more broad.
