A kind of food waste pretreatment equipment and process

Abstract

The invention relates to a kitchen waste pretreatment equipment and technology. The equipment is characterized by comprising a shell body, a garbage can lifting device mounted on one side of the shell body, a feeding device mounted on the upper portion of the shell body, an automatic separation device mounted in the shell body, an extrusion device mounted in the shell body, a smashing device mounted in the shell body, a fermenting and drying device mounted in the shell body and an ionization deodorization device mounted in the shell body. The kitchen waste pretreatment equipment and technology has the advantages of feeding and sorting automatically, being good in solid-liquid separation effect, high in efficiency, high in dehydration rate, high in fermentation treatment speed, even in fermentation, high in heating speed, capable of oxygenating automatically during fermentation, up to standard on gas deodorization, environmentally friendly, free of pollution and convenient to operate, saving manpower and the like, can process the kitchen waste generated by 300 to 500 people in 24 hours, and output 150kg to 200kg organic fertilizer with the moisture content not more than 25%.

Description

Technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a food waste pretreatment equipment and a process capable of fast, harmless and reduction treatment of food waste. Background technique [0002] At present, the existing food waste pretreatment process usually adopts steps such as waste sorting, solid-liquid separation, solid fermentation, and odor treatment. [0003] The garbage sorting step: At present, to prevent garbage from causing pollution to the environment, garbage bins are generally used for unified collection and unified treatment, while existing garbage treatment equipment requires manpower to feed in the process of adding garbage. In the process of feeding garbage, the stench from fermentation and deterioration of garbage is unbearable, and it also pollutes the environment. At the same time, in the process of disposal, these food wastes include rice, flour, food residues, vegetables, animal and...

Problems solved by technology

But it also has the following disadvantages: first, the structure is unreasonable and the production is cumbersome; second, the oxygenation gap is set at the bottom of the mixing tank, which is easy to block the material, resulting in insufficient oxygenation and fermentation; third, the temperature of the mixing tank is not easy to control, and the fermentation time is not fixed. , leading to insufficient fermentation and extremely slow processing efficiency

The commonly used deodorization methods mainly include masking method, combustion method, solution absorption method, liquid cleaning method, biological and active material adsorption method, etc. The disadvantages of these deodorization methods are: the masking method treats the symptoms but not the root cause, and the combustion method consumes a lot of energy , the high-temperature gas produced causes air pollution and high equipment investment; the liquid-phase adsorption method is often ineffective, and is not practical in cold areas; the adsorption deodorization method is currently a widely used deodorization method, which refers to A method of using activated carbon, molecular sieve or silica gel to physically or chemically adsorb odorous gas molecules, thereby effectively deodorizing, has the advantages of low cost, simple operation, and wide application range. However, conventional activated carbon materials have poor dynamic adsorption capacity and poor adsorption capacity. Shortcomings such as small capacity, and at the same time cannot solve the pollution of high-temperature gas emissions to the atmosphere
