Problems solved by technology

The biggest feature of its process is that it will not cause secondary pollution to the environment. The biggest disadvantage is high energy consumption and high processing costs.
[0010] Food waste contains a lot of nutrients that can be used. These substances are often thrown away in vain. In addition to causing environmental pollution, it is also a waste of resources

Embodiment 1

[0023] (1) After the catering waste is collected, the solid-liquid separation is carried out quickly, and the sundries are picked out at the same time, and the solid and liquid with a water content of about 70-80% are separated;

[0024] (2) The separated liquid enters the oil-water separation equipment for separation, and the grease and water are separated;

[0025] (3), adding 1-5% monoglyceride diacetyl tartrate as an emulsifier to the separated oil, and adding 1-5% Ca(OH) to the separated water 2 Or calcium salt, mixed according to the ratio of 5%-95% of the water phase and 5%-95% of the oil phase, adjust the pH value to 3.0-9.5 for emulsification treatment, after the emulsification treatment, use platinum or nickel as a catalyst in the reactor The hydrogen is subjected to hydrogenation treatment, and the obtained product is adsorbed with corn starch and then granulated to make fatty acid calcium granules;

[0026] (4), add 1-3% molasses in the separated water, in the fer...

Embodiment 2

[0029] (1) After the catering waste is collected, quickly use a solid-liquid separation device for solid-liquid separation, and at the same time pick out plastic, glass and other debris, and separate solids and liquids with a water content of about 70-80%. The liquid contains oil and water;

[0030] (2) The separated liquid enters the oil-water separation equipment for separation, and the grease and water are separated;

[0031] (3), in the isolated oil, add the monodiacetyltartrate glyceride that accounts for 4% of the oil weight as an emulsifier, and add the Ca(OH) that accounts for 3% of the water weight in the isolated water 2 , mixed according to the ratio of 50% of the water phase and 50% of the oil phase, adjusting the pH value to 5.0 for emulsification treatment, after the emulsification treatment, use platinum or nickel as a catalyst in the reactor to feed hydrogen for 2-4 hours, and the obtained product Adsorbed with cornstarch and granulated to make fatty acid calc...

Abstract

The invention provides a method of biologically making restaurant and kitchen rubbishes into feed, including: solid-liquid separation and oil-water separation. The oil separated out is made into fatty acid calcium particles by emulsifying and hydrogenating. The water separated out is added to feed saccharomycetes to obtain a saccharomycetes-containing solution. The solid separated out is sterilized at high pressure and then mixes with the solution to ferment into the feed. The method is special, the process is novel, and the final product is economic and practical. It converts the restaurant and kitchen rubbishes to the feed that has high-added value fatty acid calcium and high protein. The whole course does not discharge any pollutant and has no secondary pollution. The feed obtained contains various physiological active substances, helpful for the domestic animals and fowls to digest and assimilate the feed, thus increasing the utilization rate of the feed.

Description

(1) Technical field [0001] The invention relates to a method for treating garbage, in particular to a method for treating kitchen garbage. The invention also relates to a method for making feed by using domestic garbage. (2) Background technology [0002] Kitchen waste refers to a kind of waste discarded by major restaurants and canteens. Its main characteristics are that the amount of waste is large and the composition is complex; in addition to containing a large amount of water and salt, it also contains starch, fat, protein, cellulose and easily Rotten fermented matter. According to related reports, Beijing produces 600 tons of food waste every day, Shanghai produces 1,100 tons of food waste every day, Hangzhou urban area produces 500 tons of food waste every day, and Harbin produces about 600 tons of food waste every day. The amount of kitchen waste is huge. [0003] In the past, the main outlet for these garbage was to be taken away by pig farms and pig farmers in t...
