After-treatment system for kitchen wastes and method

Abstract

The invention relates to an after-treatment system for kitchen wastes and a method. The after-treatment system comprises a frass rotary screen; a frass separating section, a worm separating section and a waste separating section are arranged in the frass rotary screen; the frass separated from the frass separating section enters into a tempering machine; a grinder is connected with a discharging port of the tempering machine; a frass conveying device is arranged under the discharging port of the grinder; a discharging end of the frass conveying device is connected with an aerobic fermentationworkshop; a waste conveying device is arranged at the discharging end of the aerobic fermentation workshop; the separated worms enter into an imago conveying device; an optical sorting machine is arranged at the discharging end of the imago conveying device; a blanching machine is arranged at the discharging end of the optical sorting machine; a cleaning machine is arranged at the discharging endof the blanching machine; a refrigerator is arranged at the discharging end of the cleaning machine; an instant freezer is arranged at the discharging end of the refrigerator; a worm grinder is arranged at the discharging end of the instant freezer; a packer is connected with the worm grinder. The after-treatment system has the advantages that the materials after breeding worms are fully utilized,a scientific and reasonable treating system is combined with a full automatic procedure assisted by precise instruments, the degree of automation is 95% or above and the additional value of rear-endoutput is ultrahigh.

Description

technical field [0001] The patent of the present invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste post-treatment system and method. Background technique [0002] There are two methods of existing food waste treatment processes. One is the traditional physical type, which cannot achieve harmless and maximum reduction of food waste treatment. The output is only for oil extraction, biogas extraction, power generation or composting. Especially for the treatment of small-scale kitchen waste, the initial investment is huge, and the cost recovery period is very long, so the gain outweighs the gain. The other is the biological treatment type, which is limited by artificial feeding. It occupies a huge space, has high labor costs, and cannot expand the scale. It is only suitable for below 5T / day. At present, there are simple sorting of food waste for insect breeding However, the materials after raising insects are directly discarde...

[0002] There are two methods of existing food waste treatment processes. One is the traditional physical type, which cannot achieve harmless and maximum reduction of food waste treatment. The output is only for oil extraction, biogas extraction, power generation or composting. Especially for the treatment of small-scale kitchen waste, the initial investment is huge, and the cost recovery period is very long, so the gain outweighs the gain

The other is the biological treatment type, which is limited by artificial feeding. It occupies a huge space, has high labor costs, and cannot expand the scale. It is only suitable for below 5T / day. At present, there are simple sorting of food waste for insect breeding However, the materials after raising insects are directly discarded as waste or waste, which is not fully and effectively used, causing certain damage to the environment.
