High Efficient Rotary Brewery for Food Waste Drying

High Efficient Rotary Brewery for Food Waste Drying 

Brief Introduction:

High Efficient Rotary Brewery for Food Waste Drying 

(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 new developed resource that improves economic value and use kitchen leftovers reasonably by new idea, new technology.

 (2) Equipment innovation: the food waste in our country has many sundries, complex and unstable ingredient, 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 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 chemical industry. Regenerated fermentation biological feed can be processed into all kinds of new type feeds by changing feed filing material. Therefore, this type resource is regenerated and used of 100%

 (4) Project main use and applying range: kitchen waste recycling, regenerated feed grease, biological fermentation feed. This technology is suitable for city hotel, restaurant, dining and entertainment industries in our country. The centralized and scale recycle 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 a kind of device that produce 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 breeding industry. This technology changes waste into high quantity of heat feed by crushing, de-watering ans 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 energy required in individual sterilization.

Features ：

Advantage of Rotary Dryer

(1).  High production capacity

(2).  Lower consumption and operation cost

(3) .  Capable to dry different kinds of product

(4) .  Stable operation

(5) .  Uniform dried product

(6).  Both dryer and calciner, operation Temp. Up to 1000°C

(7 ).  Heat source can be steam, electricity, coal, natural gas etc.

Working Principle ：

(1).Putting the hot air and material into the first stage of drying equipment. There is a “Rotary Hollow Rolling Broken Device” in this stage, which breaks the material into scattered and “boiling suspended” state. With the hot air, the material will be keeping rolling, rotation and separation, and its surface will be dry, which can effectively prevent particles from clustering again. Thus the important transformation “high humid —→ not humid, high sticky —→ not sticky, high viscous to not viscous” is completed. With the function of Material Raising System, the material will be continuously threw and raised. The entire drying room will be filled by a complete material “curtain”, which can make the material abundantly and evenly contact with hot air, thus increasing the heat utilization and evaporation intensity.

     

(2). With the effect of special Material Feeding and Raising System, the scattered material being discharged in the first stage will be sent to the second stage cylinder. However, water vapor produced in first stage is automatically discharged at the end of first dryer. The second stage cylinder adopts “Counter-Flow and Vortex Drying Technique”. It means the material being transported in reverse direction with fresh hot air flow. It can increase the turbulence intensity and the drying efficiency. At the same time, the heat diffusion is also fastened, then the water will be speed out. Thus the evaporation also speed up. Water vapor is discharged at the end of the second dryer. However, the material is automatically sent into the third dryer under the action of specific material pushing board.

(3).The third cylinder adopts ”Inter-flow plus Reciprocating Drying Technique. Under the action of hot air and material pushing board, the wet material moves slowly and reciprocating, while the dry material moves in advance and fast. Material will be discharged automatically when they are dry enough as request.
