Product Introduction

Current disposing situation of food wastes
  Food wastes are mainly composed of food leftovers and waste food. If they are used as treated directly as common city garbage, it will not only cause environmental pollution, but also add the total amount of municipal wastes. In addition, it will also cause a waste of food. At present, there are some people who directly apply these food wastes as feedstuff. However, food wastes easily go bad in the transportation process. There are some harmful bacteria and microorganism contained in food wastes which may infect fed animals. Correspondingly, human health will be affected. The whole set of food wastes recycling system developed by Zhengzhou Taida consists of crushing system, dehydration system, secondary crushing system, drying system, sterilization system, adding feedstuff additives, pelletizing process and etc. in order to reduce resource waste and pollution caused to environment, this whole set of food wastes recycling system can realize resources reutilization and make food wastes into useful resources. After being disposed by Taida air-swept drying system, food wastes become a kind of necessary forage for husbandry industry. This technology makes full use of organic matters contained food wastes. After crushing, dehydration and drying, food wastes can become feeds with high thermal energy. With good color and uniform pellets, food wastes can be used as good superior feedstuff. This food wastes drying system totally solve the pollution problem caused by food wastes.

Difficulties of food wastes disposal
1. High moisture content: about 65% to 95%
2. Perishability: food wastes are with high organic contents. In high temperature condition, food wastes go bad easily, which will lead to new pollution.
3. High salt content: if food wastes are made into fertilizer without proper disposal, it will cause side effects to soil. After long time, it will cause land desertification.
4. High content of free fat;
5. There are virus, pathogenic bacterium and pathogenic microorganism contained in food wastes. Without proper disposal, food wastes will cause the spread of germs and infection. 
6. Contains potential bio-energy: without effective disposal, food wastes can be recycled, which can solve energy consumption.
7. Compared with municipal wastes, food wastes are with simple chemical composition. They holds less harmful and hazardous substances. With proper treatment method, food wastes can become useful energy.

Harm of food wastes
There are much organic elements contained in food wastes which will decay and breed bacteria easily in summer.
There are much residual soup and Sou water which easily cause pollution to garbage collection and transportation process.
Food wastes from landfills are main source of percolate. It is also main source of atmosphere pollution and fly.
Pigs fed by food wastes and swill oil will produce much harm to human.
At present, many cities just apply food wastes as wastes directly without any disposal. Once eating unclean water, pigs are easy to catch diseases. Some harmful substances and causatives will always stay in body of pigs. Besides, in order to reduce morbidity, livestock farm always increase dosage, which will lead to a great deal of antibiotic staying in pigs. Meanwhile, after long-term eating swill feed with high fat, there will be much fat and fatty acid accumulated in pigs. The pork quality will decrease. Plague from human are easily transferred to livestock. Even, the accumulation of hazardous substances in livestock may also bring threats to human health.

Food waste recycling system

Disposal method for common domestic food wastes
At present, china lacks effective follow-up disposal process for food wastes. In many large and medium-size food wastes, food wastes daily life are always sent to sewage directly or sent to municipal collecting-transporting system. Some cities prefer to mixed landfill or incineration. Perishable wastes cause too much difficulties for comprehensive disposal process of food wastes. Also, perishable wastes add too much disposal cost for disposal machine.
Frequently-used disposal methods for food wastes
Recycle food wastes as useful fodder
After solid-liquid separation, food wastes which are with high-solid content will be sterilized and dried. After adding certain amount of fungus, organic substances in food wastes will be degraded into biological fodder. This method is characterized by high integration and small land occupation. Food wastes can be converted into useful resources.
Recycle food wastes into organic fertilizer
Aerobic composting technology is carried out under aerobic condition. In the function of aerobic microorganism, macromolecule organic substances will be degraded into inorganic substances. Aerobic composting technology is widely applied in foreign countries.
Incineration&power generation
Combustible materials contained in food wastes can be burnt to produce energy for power generation, which will realized the food wastes cycle utilization aim. Main advantages of this method are high handling capacity and good reduction effect.
Anaerobic fermentation process
In the function of anaerobic bacteria, organic substances contained in food wastes will be degraded into small molecule from macromolecular substances. Finally, these substances will be transferred into biogas. There are many advantages for anaerobic fermentation technology such as reduction and good disposal performances. Biogas produced in the process can be used as a kind of new energy type to replenish existing energy sources. There is no odor emission no secondary pollution in anaerobic fermentation process. This method is widely accepted by public people. Owing to mature technology, this method has been widely applied at home and abroad.
Landfill treatment
After being collected and transported, food wastes will mix with other domestic garbage. Then, these wastes will be sent to landfill and be buried directly. This method is very simple and costs less running expenses. In addition, this method holds very large handling capacity. Of course, it holds various disadvantages. It will occupies too much land resources and cause pollution to underground water. Even, it will lead to secondary pollution and do harm to human health. Useful energy contained in food wastes will be wasted.

Working Principle

  Food wastes drying system will crush raw materials first in order to provide convenience for subsequent dehydration. It will save energy consumption to dry materials after dehydration. In a hot environment, harmful substances contained in food wastes can be eliminated. There is no need to set separate sterilization process, which simplify the disposal process and save energy used for sterilization. After drying and sterilizing, materials can be made into granular feedstuff, which provides convenience for package, transportation and usage. Proper amount of additives can be added according to materials’ quality and demand in order to get feed which complies with nutrition standards. This system is beneficial for the scientific breeding for fed livestock.
