A food waste source classification and pretreatment system

Abstract

The invention discloses a kitchen waste source classification and pretreatment system which comprises a solid-liquid separation unit, a rapid fermentation unit, a water-oil separation unit and a control unit; and power parts and movable components of the solid-liquid separation unit, the rapid fermentation unit and the water-oil separation unit are automatically controlled by the control unit. The kitchen waste source classification and pretreatment system is compact in structure and high in efficiency; through two-stage pretreatment, namely screw extrusion and plate pressure suction filtration, quick and effective separation of solid waste and waste liquid of kitchen waste can be realized; by employing a centrifugal separation device, efficient separation of waste water and waste oil can be realized; in addition, by employing a viscosimeter to monitor the liquid viscosity, automatic diversion of the waste water and the waste oil is realized, and the continuous operation capability is improved; the kitchen waste source classification and pretreatment system is high in production efficiency and simple to operate, and is safe and reliable; and the kitchen waste can be divided into the solid waste, waste oil and fat, and the waste water, and the solid waste can be directly converted into an organic fertilizer, so that the kitchen waste can act as a resource and can be used fully, and very high environmental and social benefits can be obtained.

Description

Technical field: [0001] The invention relates to the field of classification and treatment of kitchen waste, in particular to a source classification and pretreatment system for kitchen waste. Background technique: [0002] my country's catering industry is developing rapidly. In 2015, the revenue of my country's catering industry has exceeded 3 trillion yuan. The development of the catering industry has also led to a rapid increase in the generation of catering waste. At present, the national food waste production is about 66 million tons per year, and the treatment of food waste has become an urgent need. With the increase of population and the sustained and rapid development of the catering industry, the amount of kitchen waste generated will also increase year by year, and the growth rate is expected to be over 10%. Compared with other wastes, food waste has the characteristics of high moisture, organic matter, oil and salt content. If it is not disposed of or disposed ...
