Problems solved by technology

[0006] To sum up, it is feasible to extract the oil in the oily clay after decolorization by using the traditional process, but the problem to be solved is: it must not only ensure the smooth progress of the leaching oil extraction process, but also ensure the extraction of oil. When the white clay powder particles are not dissolved in the mixed oil in a free state; this requires the white clay to be leached to be quickly precipitated by natural precipitation, and then the mixed solvent oil on the sediment is pumped into the evaporator for circular evaporation

Embodiment 1

[0024] A process for leaching and extracting oil from waste white clay after decolorization in the edible oil industry, comprising the following steps:

[0025] Step 1, material preparation: get four sample raw materials of waste white clay, ceramic clay, gypsum powder, calcium powder, by weight percentage, wherein, described waste white clay accounts for 88% of the sum of four sample raw material weights, and described ceramic clay accounts for four 3% of the sum of the weight of the sample raw materials, the gypsum powder accounts for 5% of the sum of the weight of the four samples of raw materials, and the calcium powder accounts for 4% of the sum of the weight of the four samples of raw materials; The particle size of the gypsum powder and the calcium powder is 180 mesh to 200 mesh;

[0026] Prepare solvent oil according to twice the sum of the weight of the aforementioned four raw materials;

[0027] Step 2. Stirring: Pour the ceramic clay, the gypsum powder and the calc...

Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is that in step 1, the waste clay accounts for 90% of the weight sum of the four raw materials, the ceramic clay accounts for 2.5% of the weight sum of the four raw materials, and the gypsum powder Accounting for 4% of the sum of the weight of four samples of raw materials, the calcium powder accounts for 3.5% of the sum of the weight of the four samples of raw materials; get solvent oil according to 2 times of the sum of the weight of the aforementioned four samples of raw materials.

Embodiment 3

[0034] The difference between this embodiment and Embodiment 1 is that in step 1, the waste clay accounts for 92% of the weight sum of the four raw materials, the ceramic clay accounts for 2% of the weight sum of the four raw materials, and the gypsum powder Accounting for 3.5% of the sum of the weight of four samples of raw materials, the calcium powder accounts for 2.5% of the sum of the weight of the four samples of raw materials; get solvent oil according to 1.9 times of the sum of the weight of the aforementioned four samples of raw materials.

Abstract

The invention provides a technique for extracting oil through the leaching of waste carclazyte after the decoloring of an edible fat industry which includes the following steps: step 1, preparing materials: four materials of waste carclazyte, ceramic clay, gypsum powder and calcium powder are prepared according to a proportion; solvent oil which is 1.8 to 2.4 times of the sum of the weights of the four materials is prepared; step 2, stirring: the ceramic clay, the gypsum powder and the calcium powder are poured into a stirring machine and fully stirred; step 3, re-stirring: the solvent oil and the waste carclazyte disclosed in step 1 are poured into the stirring machine and fully stirred to obtain a mixed material; step 4, deposition: the obtained mixed material is naturally deposited forobtaining a deposit and mixed oil; step 5, circulating and evaporating: the mixed oil is sucked into an evaporator for circulating and evaporating until qualified crude oil is obtained. The techniquehas the advantages of simple and practical flow for extracting oil through leaching, high efficiency of extracting oil through leaching and good quality of the obtained crude oil.

Description

technical field [0001] The invention relates to a process for leaching and extracting edible oil, in particular to a process for leaching and extracting oil from waste white clay after decolorization in the edible oil industry. Background technique [0002] According to relevant data records, my country's current annual oil refining capacity has reached 24 million tons per year. In the refining process, white clay needs to be used for decolorization treatment. Calculated according to the addition of 3% white clay, the total annual consumption of white clay can reach 720,000 tons; it has been proved by tests that the residual oil in waste white clay can reach 33%, then, 720,000 tons There should be 72×33% of oil in one ton of waste clay = 237,600 tons. At present, the waste white clay in the whole country is basically in a state of being discarded, which not only pollutes the environment, but also wastes resources. However, 2 / 3 of the edible oil in our country is imported, a...
