Embodiment 1

[0066] Refer to attached figure 1 .

[0067] The organic waste treatment method of the present invention utilizes organic waste (kitchen leftovers; food bottom corners, etc.) to collect and concentrate. Crush large pieces and squeeze out excess water. Inoculate microbial feed fermentation strains, rapidly ferment under certain conditions in the biological fermentation tank (period is about 36 hours) to produce animal and vegetable protein, and then add a certain proportion of animal and vegetable protein carriers and other auxiliary materials to become feed with good commercial shape additive. This feed additive can also add corresponding ingredients according to different needs. Organic waste treatment methods include waste collection, draining and oil draining, and sterilization treatment. The specific process is as follows:

[0068] 1. Collection and transportation of organic waste (kitchen leftovers)

[0069] Collect kitchen leftovers and organic waste at the lower co...

Embodiment 2

[0092] Refer to attached figure 1 .

[0093] The organic waste treatment method uses organic waste (kitchen leftovers; food corners, etc.) to collect and concentrate. Crush large pieces and squeeze out excess water. Inoculate microbial fertilizer fermentation strains, quickly ferment in a biological fermentation tank (period of about 48 hours) to become a decomposed organic fertilizer, and then mix a certain proportion of nitrogen, phosphorus, and potassium fertilizers to become an organic compound fertilizer with a good commercial shape ; Or mixed with nitrogen-fixing, phosphorus-dissolving, potassium-dissolving functional bacterial fertilizers to become organic biological compound fertilizers. Different special fertilizer formulas are designed according to different soils and different crops, which can be applied to various types of soil and crops. Integration with soil testing and formula fertilization technology can make special fertilizers more targeted. Organic waste...

Embodiment 3

[0103] Refer to attached figure 2 , image 3 and Figure 4 .

[0104]The organic matter dehydration press includes a drive motor 1, a reducer 2, and the drive motor 1 drives a screw 7 through the reducer 2. The helix 7 is assembled on the bearing support 12, and is a helix structure with a pitch shrinkage. The outside of the spiral body 7 is a cylindrical structure composed of grid bars 5 . The port of the pressing screw body 7 is a conical structure, and the conical surface 8 is matched with the shaft conical surface 9 to form an organic material extrusion port. The coaxial conical surface 9 is the conical surface of the coaxial sleeve 13 assembled on the drive shaft 6 . The coaxial sleeve 13 is assembled on the rotating shaft 6 through the pin 10 and the adjusting nut 11 . Adjusting the nut 11 makes the coaxial sleeve 13 move through the pin 10, thereby changing the distance between the conical port of the spiral body and the coaxial conical surface 9 to change the si...

Abstract

The present invention relates to organic waste treating process and apparatus, and belongs to the field of comprehensive resource utilizing technology. The organic waste treating process includes the steps of: collecting kitchen leftover; squeezing to reduce water content to 40-70 %; sterilizing; and adding microbe seed, and fermentation first at 20-45 deg.c, 3-10 rpm stirring speed and exhaust for 30-50 hr and then at 65-70 deg.c for 8-15 hr to obtain the fermented product. The apparatus includes a spiral conveyer with driving mechanism, spiral conveying barrel and flange support; and a dewatering squeezer with driving mechanism, pitch reducing spiral unit and grating barrel. The present invention has simple structure, high utilization, great treating capacity and other advantages.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of resources, and in particular relates to an organic waste treatment method and a device thereof. Background technique [0002] At present, organic wastes such as food leftovers in hotels, restaurants, and canteens, food waste, etc., its main solid components include organic substances such as starch, dietary fiber, animal fat, etc. A lot of sewage and odor are produced, which increases the possibility of germs, mosquitoes and flies breeding and disease transmission. The existing treatment methods include simple landfill treatment, which causes secondary pollution. There is also a processing method of collecting, draining, dehydrating, drying and pulverizing to make feed raw material waste. The method adopts the process of dehydration, drying and pulverization, the process is complex, the energy consumption is high, the product is feed raw material, fermented feed or fertilize...
