Problems solved by technology

This has led to the fact that the raw materials obtained by the food waste centralized treatment plant (site) are generally food waste 12 to 24 hours after generation. Since there is no suitable technology for instant collection, pretreatment and storage of food waste at the production site, waiting When the food waste is transferred to the centralized treatment plant, it has rotted and deteriorated, which increases the difficulty of treatment and reduces the economic benefits of the treatment plant

Embodiment 1

[0045] Such as figure 1 As shown, a kind of food waste collection and pretreatment equipment comprises a frame 8, a food waste solids airtight storage tank 19, and a material liquid temporary storage tank 16 is installed on the said frame 8, and the material liquid is left to settle and store liquid Tank 5, antibacterial agent feed liquid storage tank 1, vibrating screen 10 installed below the feed liquid static settlement liquid storage tank 5, antibacterial agent feed liquid turnover liquid storage tank 12 and oil-water separator 13, the machine The above-mentioned devices provided on the frame 8 communicate with each other through pipelines, automatically controlled delivery pumps or automatic control valves arranged on the pipelines. Specifically, the feed-liquid temporary storage tank 16 communicates with the feed-liquid static settlement liquid storage tank 5 through pipelines and feed-liquid delivery pump 17, and the feed-liquid static settlement liquid storage tank 5 i...

Embodiment 2

[0070] A method for collecting and pretreating food waste, referring to Example 1, the difference is that the standing time in step b standing for solid-liquid separation is 180 minutes, and in step d, 15 liters of plant milk with a pH value of 4 is used Soak in the bacillus fermentation culture solution for 2 minutes, and in step e, use a centrifuge to separate the solid-liquid from the food waste sediment soaked in the Lactobacillus plantarum bacteriostatic agent feed solution.

Abstract

The invention discloses equipment and a method for collecting and pretreating kitchen waste. When the kitchen waste is just generated, water is immediately added to carry out grinding and pretreatment is carried out; in the pretreating process, a bacteriostat is used for inhibiting sundry fungi from growing so as to prolong the guarantee period of the kitchen waste and provide fresh raw materials for subsequent biochemical treatment; after bacteriostasis treatment, the kitchen waste does not need to be cleaned and transported every day, so that cleaning and transporting cost is reduced; meanwhile, in the whole collecting, pretreating, storing and transporting process, the kitchen waste is sealed, other garbage is prevented from being mixed into the kitchen waste and independent collection and treatment of the kitchen waste are implemented; in the pretreatment process, solid and liquid separation is carried out, so that when the quantity of the kitchen waste is reduced, moisture contained in the kitchen waste is also reduced. Through the adoption of the technology, separated collection and treatment of the kitchen waste and municipal domestic waste can be implemented at source and excellent social benefits and economic benefits are achieved.

Description

Technical field: [0001] The invention relates to the field of recycling and processing of kitchen waste, in particular to a device and method for collecting and pretreating kitchen waste. Background technique: [0002] Kitchen waste mainly includes organic waste generated in catering services, family kitchens, food processing, and food circulation. It is generally leftovers, leftovers of kitchen raw materials, waste water from washing pots and dishes, and melon rind and fruit scraps. mixture. [0003] Food waste is characterized by high water content, high organic matter content, and high salt content, so it is easy to rot and smell, breed bacteria and viruses, and pollute the environment. The generation of kitchen waste is characterized by scattered points of generation, the amount of kitchen waste produced at each point is relatively small, and the space of the point of generation is small. However, food waste contains protein, oil, starch, dietary fiber and other nutrie...
