Problems solved by technology

[0002] Most of the oil feet after refining in vegetable oil factories are discarded, incinerated or buried. This is not in line with the current principle of full utilization of energy resources. At the same time, it also causes great pollution to the natural environment.

With the advancement of energy resources recycling technology, there are also methods of recycling vegetable o...

Abstract

The invention discloses a method for producing fertilizer by utilizing vegetable oil residues, which comprises extracting neutral oil from vegetable oil residues, adding plant ash and ammonium bicarbonate, stirring well, stacking and fermenting or fermenting in a fermentation tank, and then It only needs to be processed; the post-processing includes granulation, drying and aseptic treatment. The method of the present invention can turn waste into valuables in vegetable oil factories, and turn pollutants into beneficial objects, which is in line with the current theme of saving energy resources and environmental protection. At the same time, the method has simple operation and low production cost. The compound fertilizer obtained by the method has reached the industry standard NY525‑2002 of the Ministry of Agriculture.

Example Embodiment

[0008] Example 1

[0009] After saponification of cottonseed oil feet from vegetable oil plants to remove neutral oil, 60% of the cottonseed oil feet after saponification and removal of neutral oil are calculated based on the total weight of the fermented material, and 40% of the waste plant ash from the biological power plant is sufficient After stirring, add 10% ammonium bicarbonate, ferment in the fermentation tank, the fermentation temperature is 20-35℃, and the fermentation time is about 15 days. After the fermentation is completed, the organic compound fertilizer product is obtained through granulation, drying and aseptic treatment. The product has been tested and reached the NY525-2002 standard. The test results are shown in Table 1.

Example Embodiment

[0010] Example 2

[0011] After saponification of rapeseed oil feet from vegetable oil plants to remove neutral oils, based on the total weight of the fermentation material, 50% of the cottonseed oil feet after saponification to remove neutral oils, and 30% of waste plant ash from bio-power plants After fully stirring, add 20% ammonium bicarbonate, ferment in the fermentation tank, the fermentation temperature is 20-35℃, and the fermentation time is about 15 days. After the fermentation is completed, the organic compound fertilizer product is obtained through granulation, drying and aseptic treatment. , The product has been tested and meets the NY525-2002 standard. The test results are shown in Table 1.

Example Embodiment

[0012] Example 3

[0013] After saponification of soybean oil feet from vegetable oil plants to remove neutral oil, based on the total weight of the fermentation material, take 55% of cottonseed oil feet after saponification to remove neutral oil, and 35% of waste plant ash from biological power plants. After stirring, add 10% ammonium bicarbonate, ferment in the fermentation tank, the fermentation temperature is 5-10℃, and the fermentation time is about 20 days. After the fermentation is completed, the organic compound fertilizer product is obtained through granulation, drying and aseptic treatment. After inspection, the product meets NY525-2002 standard.
