Description

Technical Field

[0001] This invention relates to the field of daily chemical application technology, specifically to a preparation process for degreasing wastewater from the fermentation of pure natural plant oils. Background Technology

[0002] In daily life, cleaning grease stains is a headache for people, and if not cleaned properly, it can seriously affect their physical and mental health. Kitchen grease mainly forms from dripping cooking oil and evaporation due to heat, contaminating utensils. Combined with dust, this accumulates over time to form a thick, highly adhesive layer of grease. This type of grease is difficult to remove with ordinary cleaning agents. Furthermore, most detergents used daily, especially dishwashing detergents, are primarily liquid, formulated with surfactants, various additives, and auxiliary agents. With the rapid economic development and gradual improvement of living standards in my country in recent years, people have increasingly higher demands for the safety of cleaning products. Therefore, the detergent industry in my country still has considerable room for development.

[0003] Currently, commonly used kitchen grease cleaning methods mainly employ strong alkaline cleaning and solvent-based cleaning techniques. While both have high grease removal rates, they are unsafe to use and can cause significant corrosion and damage to human skin and kitchen facilities. Therefore, the development of efficient, safe, and environmentally friendly kitchen grease cleaners has significant application value and promising prospects.

[0004] Chinese patent application CN 105596231 A discloses a household oil stain cleaner, which is composed of the following components in parts by weight: 2-4 parts potassium chlorate, 1-3 parts sodium silicate, 3-5 parts soap solution, 5-9 parts hydrogen peroxide, 2-6 parts alkyl glycoside, 2-5 parts linalyl acetate, 6-8 parts surfactant, 6-12 parts biological disinfectant, and 22-36 parts distilled water.

[0005] While many existing technologies claim to effectively clean heavy oil contamination, existing cleaning agents often suffer from drawbacks such as incomplete removal of stains, time-consuming and labor-intensive processes, and high cleaning costs. Furthermore, most oil stain cleaners contain organic solvents and sodium hydroxide, posing significant safety hazards during use and transportation, and also greatly increasing transportation costs.

[0006] Therefore, in order to meet the public's ever-increasing demand for quality of life, promote the spirit of craftsmanship, and develop plant fermentation technology, we designed a green, environmentally friendly, and healthy process for preparing pure natural plant oil fermentation wastewater. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technologies and provide a preparation process for oil removal wastewater from the fermentation of pure natural plant oil.

[0008] To solve the above technical problems, the technical solution provided by the present invention is a preparation process for oil removal wastewater from pure natural vegetable oil fermentation, which includes the following steps: Step 1: Prepare materials, softened water, 1-2 kinds of edible vegetable oil, and edible catalyst;

[0009] Step 2: Mixing. Mix the edible vegetable oil, edible catalyst and softened water evenly according to the ratio.

[0010] Step 3: Decomposition. Place the mixed materials into a high-pressure boiler and cook under high pressure for 30-60 minutes to decompose the mixture.

[0011] Step 4: Fermentation. After cooling the above materials, place them separately into transparent plastic buckets with a capacity of 0.5 to 10 tons. Then place the plastic buckets containing the liquid in the sun for 250 to 365 days. Under the action of sunlight and heat, enzymes will be slowly produced.

[0012] Step 5: Sun exposure and fermentation. During the sun exposure process, add edible catalyst according to the ratio every day, extract samples daily, and test the cleaning effect and each component. It can be used after the standard is met.

[0013] The advantages of this invention compared to existing technologies are: it utilizes solar energy to promote fermentation, saving energy and production costs; the degreasing wastewater is fermented using edible vegetable oil and edible catalyst, making it a pure natural degreasing wastewater, thus protecting the environment and being gentle on hands during use; this degreasing wastewater can remove oil stains, odors, and bacteria, achieving a degreasing effect of 99%; it is safe, environmentally friendly, and easy to store and transport.

[0025] Degreasing ability test

[0026] The degreasing ability of the kitchen degreasing detergents prepared in Examples 1-10 and Comparative Examples 1-10 of this invention was tested against commercially available detergents.

[0027] 1. Oil removal rate test

[0028] Stainless steel plates, glassware, and ceramic plates were cleaned with anhydrous ethanol, dried, and weighed (recorded as M1). Rapeseed oil was poured into the plates and soaked for 10 seconds, then dried for 20 minutes. The remaining oil was wiped off the plates with filter paper, and the weight was recorded as M2. A 2% detergent solution (300 mL) was prepared and placed in a 500 mL beaker. The beaker was heated in a water bath to 35±2℃. The plates were placed in the beaker and stirred twice with a stick. The plates were then placed in a drying oven at 70℃ for 4 hours. After cooling to room temperature, the weight was recorded as M3. Each group was measured twice in parallel. The oil removal rate was calculated using the following formula:

[0029] Oil removal rate = (M2-M3) / (M2-M1)×100%

[0030] 2. Detergent cleaning power test

[0031] Stainless steel plates, glassware, and ceramic plates were cleaned with anhydrous ethanol, dried, and weighed (recorded as N1). A mixture of equal parts rapeseed oil and lard (15%), cornstarch (15%), milk powder (8%), egg liquid (30%), and water (32%) was poured into the plates and soaked for 10 seconds. The plates were then dried for 20 minutes. Unabsorbed oil was wiped off with filter paper, and the plates were weighed again (recorded as N2). A 2% detergent solution (300 mL) was prepared and placed in a 500 mL beaker. The beaker was heated in a water bath to 35±2℃. The plates were placed in the beaker and stirred twice with a stick. The plates were then placed in a 70℃ drying oven for 4 hours and cooled to room temperature. The plates were weighed again (recorded as N3). Each group was measured twice in parallel. The stain removal rate was calculated using the following formula:

[0032] Decontamination rate (%) = (N2-N3) / (N2-N1) × 100%

[0033] 3. Pesticide residue removal rate test

[0034] The prepared detergent was formulated into a 2% solution. Apples purchased from the same batch were immersed in the solution for 3 minutes, rinsed three times with water, and dried. The apples were then analyzed by gas chromatography-mass spectrometry (GC-MS), with each group measured twice in parallel. The pesticide residue removal rate was calculated.

[0035] Pesticide residue removal rate (%) = Pesticide residue content after washing / Pesticide residue content before washing × 100%

[0036] The results are shown in Table 2.

[0037] Table 2

[0038]

[0039]

[0040] As can be seen from the table above, the kitchen degreasing detergents prepared in Examples 1-3 of the present invention have good degreasing ability and pesticide residue removal ability.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments described are merely one example of the invention's implementation; the invention is not actually limited thereto. In conclusion, if those skilled in the art are inspired by this description and, without departing from the spirit of the invention, design similar methods and embodiments without creative effort, all such designs should fall within the protection scope of the present invention.
