Restaurant and kitchen refuse regenerative protein fodder, grease, fermented fodder four-section process

Abstract

The present invention discloses a four-stage process for regenerating protein feed, oil and fermented feed. Said four-stage process is implemented mainly by using 39 equipments, and said four-stage process includes dining hall and kitchen garbage pretreatment stage, stage for regenerating protein feed, stage for regenerating oil and stage for regenerating fermented feed. Said invention also provides the concrete steps of the above-mentioned every stage.

Description

technical field [0001] The invention relates to a process for resource recycling and utilization of kitchen waste, in particular to a four-stage process for regenerating protein feed, oil and fermented feed from kitchen waste. Background technique [0002] At present, there are two ways to recycle food waste (also known as kitchen waste) in my country. One of them is to use physical and mechanical methods to regenerate food waste into feed protein powder. The waste liquid discharged during the regeneration process must reach The national waste water discharge level 3 standard is difficult to deal with, and the equipment and operating costs are high, which is unbearable for users; the other is to use bioengineering to regenerate food waste into organic fertilizers, which is difficult to sell and has poor economic benefits. Therefore, The above two treatment methods have great resistance to the promotion and application of resource utilization and large-scale recycling of kitche...

[0003] The purpose of the present invention is to regenerate the kitchen waste into protein feed, oil and fermented feed in four different sections on the same production line by using physical, mechanical and biological engineering treatment techniques. The protein feed is The raw material of full-price feed, oil is the raw material of chemical products, and fermented feed can be used as full-price feed; realize the recycling and industrialized recycling of high value-added kitchen waste, and at the same time achieve zero discharge of waste liquid, solving the impact of waste liquid discharge on Pollution of the natural environment; the present invention designs a four-stage process for regenerating protein feed, oil, and fermented feed from kitchen waste, mainly consisting of a self-contained unloading hopper, a homogenizer, a bag breaking machine, a winnowing machine, a chain conveyor, Vibrating separator, waste collection drum, dehydrator, vertical screw conveyor, mixed storage tank, circulation conveyor, return conveyor, horizontal screw conveyor, first magnetic separator, collecting hopper, press, inclined screw Conveyor, dryer, air-cooled conveyor, second magnetic separator, pulverizer, rotary screen machine, protein feed bagging machine, mixed liquid pump, mixed liquid storage tank, oil picker, heater, grease storage tank, Degreasing mixed liquid pump, mixed liquid meter, blender, strain storage tank, strain conveying and measuring equipment, feed filling storage tank, feed filling conveying and measuring equipment, mixed material conveyor, fermentation tank, fermented feed It is composed of conveyor and fermented feed bagging machine; it is characterized in that: the four-stage process of kitchen waste regenerated protein feed, oil and fermented feed, the process flow can be divided into pretreatment section, regenerated protein feed section, and regenerated oil according to the nature of work section, regenerative fermented feed section, food waste pretreatment section including self-conveyed unloading hopper, homogenizer, bag breaker, winnowing machine, chain plate conveyor, vibration sorting machine, waste collection tank, dehydrator, vertical Screw conveyor, mixed storage tank, circulation conveyor, return conveyor, horizontal screw conveyor, first magnetic separator, collecting hopper, press, inclined screw conveyor, food waste recycled protein feed section including dryer , air-cooled conveyor, second magnetic separator, pulverizer, rotary sieve machine, protein feed bagging machine, food waste recycled oil section includes mixed liquid pump, mixed liquid storage tank, heater, oil picker, oil storage tank, food waste regeneration fermentation feed section includes degreasing mixed solution pump, mixed solution meter, blender, strain storage tank, strain delivery and metering equipment, feed filling storage tank, feed filling delivery and metering equipment, Mixed material conveyor, fermentation tank, fermented feed conveyor, fermented feed bagging machine; among them, in the process flow of the food waste pretreatment section, there are bag breaking machine, winnowing machine, vibrating sorting machine, rotary screen machine, the first A magnetic separator cleans out the solid harmful waste mixed in the food waste, and the dehydrator and squeezer remove the oil and water mixed and infiltrated in the food waste, as well as a small amount of solid particles that are incidentally lost. The three-phase mixed liquid of solid, oil and water is pumped to the mixed liquid storage tank through the mixed liquid, which is used as the raw material of recycled oil and fermented feed; in the process flow of the kitchen waste recycled protein feed section, the wet material from the pretreatment section is sent to the dryer Drying, cooling by air-cooled conveyor, crushing by pulverizer, screening by rotary sieve machine, and the powdery protein feed produced is bagged by protein feed bagging machine; In the technical process, the mixed liquid is heated by the heater in the mixed liquid storage tank, the viscosity of the oil is reduced, and the oil and water are separated by gravity, and then the oil floating on the surface of the mixed liquid is taken out by the oil picker and transported to the oil storage tank; In the process flow of the regenerative fermentation feed section, the degreasing mixed liquid pump sends the solid, oil, and water three-phase mixed liquid after degreasing and oil extraction in the mixed liquid storage tank to the blender through the mixed liquid meter. The conveying and metering equipment sends the bacteria stored in the strain storage tank and the feed filler stored in the feed filler storage tank to the blender quantitatively by the feed filler conveying and metering equipment, and the blender After the mixed liquid, fermented strains and feed materials are evenly mixed, the mixed material conveyor is sent to the fermentation tank, and after fermentation, the fermented feed in the fermented tank is sent to the fermented feed for bagging by the fermented feed conveyor Machine-packed bagging, so far, the technical goal of four-stage process of regenerated protein feed, oil and fermented feed from kitchen waste has been realized
