Food waste also called the kitchen waste (commonly known as swill, hogwash, household refuse, pigwash), is the generic terms of leftovers, dining table waste, and kitchen waste. Its main ingredients are rice, flour, starch types, bone, meat, oil, skin, thorn, scales, etc. It richly contains nutrient substances ( such as vitamins, starch, protein, fat, dietary fiber, fatty acid, sugar, salt, etc) and mineral substances (such as calcium, sodium, magnesium, potassium, and iron, etc). Food waste is suitable for being used as feed after being processed.

Innovation Points

(1). Technical innovation: Based on economic value of the kitchen leftover, the kitchen leftover regeneration protein feed, regeneration oil, fermentation biological feed, organic fertilizer technology uses synthesis technique(physical, mechanical and biological, etc) to classify, extract, and process three kinds of products of different economic value in the same production line, including protein feed, grease, biological feed fermentation. They are newly developed resource that improves economic value and uses kitchen leftovers reasonably by a new idea, new technology.

(2) Equipment innovation: the food waste in our country has many sundries, complex and unstable ingredients, high oil content, therefore, the key equipment of the complete equipment is a dedicated device that is developed after innovation and transformation. The complete equipment adopts a fully sealing automatic logistics system and central program controlling system, thus realizing the kitchen leftovers regeneration process and use continuous, automatic and large-scaled.

(3) Regenerated Product Innovation: classifying and extracting the kitchen leftover, meanwhile regenerating protein feed, grease, biological feed fermentation three products belong to international innovation at present. The protein content of regenerated protein feed reaches 32-37%, which can take the place of fish feed. Regenerated grease is a raw material in the chemical industry. Regenerated fermentation biological feed can be processed into all kinds of new type feeds by changing feed filling material. Therefore, this type of resource is regenerated and used 100%

(4) Project main use and applying range: kitchen waste recycling, regenerated feed grease, biological fermentation feed. This technology is suitable for a city hotel, restaurant, dining and entertainment industries in our country. The centralized and scale recycling of kitchen leftover produced by enterprises, public institutions, and school canteen.



The food waste dryer and feeding complete equipment developed by our company is a kind of device that produces high protein feed by using restaurant, canteens scrap swill as raw material, through quick edulcoration, extruding and de-watering, disinfection, sterilization, and drying. It is also called the kitchen waste dryer, including steps such as human(automatic) sorting, solid-liquid separation, smashing, oil-water separation, solid fermentation, drying, and sterilization, grinding, packing, adding feed additive and pelleting, etc. It reduces resource gratuitous waste and food waste environmental pollution. This system introduces complete machine equipment, processes food waste, and achieves resource regenerating use. It turns food waste into wealth, becoming a necessary feed in the breeding industry. This technology changes waste into a high quantity of heat feed by crushing, de-watering and drying. The feed is of golden color, even particle, which completely solves the environmental pollution caused by city catering groups when they abandon food waste at will and don’t reuse the food waste.

This system smashes material firstly, which is convenient for subsequent dehydration. After dehydration, it dries the dehydration materials, which decreases the drying heat consumption. In addition, during the high-temperature drying process, it inactivates the harmful microbe inside the material. Setting up individual sterilization technology is not required, which simplifies the material processing process, saves the energy required in individual sterilization.

High-performance price ratio

Automatic control, to ensure the drying of sawdust water even and stable.Automatic stone removing and iron removal can ensure that the impurities of the sawdust are not in the rear process.The required investment of equipment is 1/6 of imported products.


Energy conservation

Compared with the single-cylinder drier, the utility model reduces the occupation and the civil investment by about 50%, the design of flow rate adjustment devices ensures the control of the drying period. Raise heat efficiency by 20% and effectively control the drying time.


Better quality

Cylinder self insulation, thermal efficiency of more than 70%, With tail drive, the transmission is more stable and reliable; completely change the wheel rotation, often slip shadow, Sound production phenomenon.


Widely used

Frequency control is adopted to control material flow, and the final water can be easily controlled according to the needs of users Sub index. The air outlet temperature is low, and the dedusting equipment can be used for a long time.
