Problems solved by technology

In addition, the airtightness of transport vehicles and containers is poor, leaking, dripping and leaking during transportation, producing a large amount of leachate to continue to pollute the environment, making the food waste treatment industry an industry disgusted by citizens, and the collection and transfer of food waste. It is carried out at night, which increases the difficulty of supervision
Due to the influence of unscrupulous collectors, the amount of garbage collected by regular food waste treatment plants is unstable or even unable to receive raw materials, making it difficult to maintain stable operations

Embodiment 1

[0048] A method for collecting and storing kitchen waste, the flow chart is as follows figure 1 shown, including the following three steps:

[0049] a. Adding water and crushing: Put the freshly produced kitchen waste into a food waste shredder (wastemaid brand, product of Anaheim International Marketing Company, USA, model BIOS50-2) installed under the kitchen sink and add water for crushing. The flow rate of water is 30-50 ml / s, so that the ratio of the mass of food waste to the mass of water is about 1:1-5, and a uniform mixed solution of food waste particles and water is obtained;

[0050] b. Fermentation preservation: the mixed solution of food waste particles and water obtained in step a falls into the fermentation storage tank by centrifugal force and gravity, and is fermented and stored at 55°C to obtain a fermentation storage solution; the fermentation storage tank is preset with fermentation bacteria species, the initial pH value is between 6.5 and 7.5, and the food...

Embodiment 2

[0067] A method for collecting and storing kitchen waste, the flow chart of which is as follows image 3 As shown, referring to Example 1, the difference from Example 1 is that in step b, D-lactic acid-producing heat-resistant Bacillus coagulans is used for anaerobic fermentation, the gas supply device is not working, and 5-20% calcium hydroxide is used to The aqueous solution adjusts the initial pH value of the fermented seed liquid between 6.5 and 7.5.

[0068] Please refer to Figure 4, the present invention also provides a device for collecting and fermenting food waste in flat environment places: it includes a fermentation storage tank, a temporary storage transfer box 217, a washing basin 212 installed on the ground or in the kitchen on the first floor and installed in the Food waste shredder 211 (wastemaid brand, American Anaheim International Marketing Company product, model is BIOS50-2) (Anaheim Sheng brand, model is BIOS50-2) below the washing tub 212; the fermentat...

Abstract

The invention discloses a method and device for collecting and preserving kitchen waste. The kitchen waste is immediately added with water and crushed when being just produced, the kitchen waste is collected to a fermentation preserving tank for conducting biological fermentation treatment, heat resisting lactic acid bacteria are used for high temperature fermentation to guarantee the optical purity of produced lactic acid and restrain the growth of infectious microbes, after fermentation processing and reserving are conducted in site, a closed vessel is used for collecting fermentation liquors to a centralized treatment plant for centralized subsequent processing, the treatment process of full closed collecting and fermentation preserving is conducted, the kitchen waste is restrained from being rotted or generating foul smells, secondary pollution in the collecting and transporting process of the kitchen waste is avoided, environmental protection is facilitated, and the health of people is protected. Fermentation products can be used as raw materials for biology-base degradable plastics, and good social benefits and economical benefits are achieved.

Description

Technical field: [0001] The invention relates to the field of recycling and processing of kitchen waste, in particular to a method and device for collecting and storing 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. [0004] At present, the treatment method of kitchen waste generated by households in our country is generally to put it into plastic bags and throw it directly into corridors or street trash cans, and then transfer it to landfills or incineration plants for terminal treatment. In this proce...
