Embodiment 1

[0041] The food residues, slops, and non-edible animal and plant waste edible oils and oil-water mixtures produced in hotels, guesthouses, catering industries, government agencies, schools, and unit canteens are separated and dehydrated by machinery. After high-temperature fermentation, deodorization, disinfection and sterilization, etc., it is digested and processed into decomposed powder, and then dried, milled, and sieved to make food waste powder with a particle size of -0.18mm;

[0042] After the fruit of Jatropha curcas is dried and separated, the grains are crushed, heated, steamed and fried, and the slag cake after the oil is extracted by mechanical processing is fermented at high temperature, dried, milled and sieved to make a particle size of -0.18mm jatropha oil dry cake powder;

[0043] A kind of rice bran separated from rice processing is steam-heated, and the residue cake after extracting oil by mechanical pressing is fermented at high temperature, dried, milled,...

Embodiment 2

[0048] Get the kitchen waste powder material 45kg of embodiment 1, Jatropha curcas grease dry cake powder material 35kg, rice bran dry cake powder material 25kg, cottonseed dry cake powder material 35kg, bone meal 15kg, unslaked lime powder material 18kg, calcium hydrogen phosphate 13kg, nitric acid 8kg of ammonium, 8kg of potassium sulfate, 0.8kg of sodium borate, 6kg of ferrous sulfate and 12kg of magnesium sulfate, the above raw materials are mixed evenly with a biaxial paddle mixer to make a food waste organic compound fertilizer product.

Abstract

The invention relates to an organic compound fertilizer produced from kitchen rubbish and a preparation method thereof. A kitchen rubbish organic compound fertilizer is prepared by uniformly mixing and stirring kitchen rubbish, barbadosnut grease oil cakes, rice bran oil cakes, cotton seed oil cakes, bone meal, quicklime powder, calcium hydrophosphate, ammonium nitrate, potassium sulfate, sodium borate, ferrous sulfate, magnesium sulfate and the like serving as raw materials with a double-shaft paddle mixed stirrer. The organic compound fertilizer has the advantages and effects of containing of various nutrients such as nitrogen, phosphorus, potassium, multiple micro elements, organic acids and the like for meeting the growing requirements of crops, environmental friendliness, low cost, good benefit, prevention of secondary pollution of kitchen rubbish, environmental friendliness, saving of lands, and the like.

Description

technical field [0001] The invention relates to an organic compound fertilizer produced from kitchen waste. Specifically, the kitchen waste is separated from oil and water by machinery, dehydrated, then fermented at high temperature, sterilized, dried, pulverized and sorted. It is an organic compound fertilizer produced as the main raw materials from jatropha curcas dried cake, rice bran dried cake, cottonseed dried cake and bone meal, which belongs to the field of waste treatment. [0002] The invention also relates to a method for manufacturing the kitchen waste organic compound fertilizer. Background technique [0003] With the rapid development of my country's economy, the scale of urbanization continues to expand and the urban population is highly concentrated, and people's consumption levels continue to increase, making the scale and speed of the development of my country's catering industry large and fast, and the amount of kitchen waste is also increasing. , the envi...
