Description

Microbial washing sheet for washing tableware

Technical Field

The invention belongs to the technical field of daily chemicals, and particularly relates to a microbial washing sheet for washing tableware.

Background

With the continuous improvement of the living standard and environmental protection consciousness of people, tableware washing products are continuously pushed out and become new, and iteration is carried out in the direction of environmental protection and health.

Most of the active ingredients of the traditional tableware washing products are chemically synthesized cationic, anionic or neutral surfactants which have good deoiling effect, but the chemically synthesized surfactants can not be completely biodegraded in natural environment and can be accumulated in the nature for a long time, so that the water quality can be polluted, the growth and the propagation of aquatic organisms can be influenced, and the harmful substances to human bodies can be enriched.

The bleaching agent in the traditional tableware washing product generally selects peroxide and an activating agent thereof, the peroxide has excellent bacteriostatic effect on bacteria on the surface of tableware, but the peroxide is inflammable and explosive, has potential safety hazards in the production and transportation processes, and can partially remain on the surface of the tableware after the tableware is cleaned, thereby affecting the human health.

Disclosure of Invention

The invention aims to solve the defects of the prior art and provides a microbial washing sheet for washing tableware, which does not contain a surfactant, phosphorus or peroxide in a formula, has long shelf life, is suitable for various adverse environments, cleans tableware by microorganisms, is environment-friendly, green and environment-friendly, has excellent cleaning effect, and has certain practical value and market prospect.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a microbial washing tablet for washing tableware is characterized in that the tablet is prepared from the following raw materials in percentage by weight: 20-30% of laminated silicon, 20-25% of Marc copolymer, 30-50% of anhydrous trisodium citrate, 4-5% of polyethylene glycol (PEG 8000) and 8-10% of microorganism.

Furthermore, the microbial washing sheet for washing tableware is characterized by being a tablet prepared from the following raw materials in percentage by weight: 24-28% of laminated silicon, 22-23% of Marc copolymer, 35-40% of anhydrous trisodium citrate, 4.5-5% of polyethylene glycol (PEG 8000) and 8-9% of microorganism.

Further, the microorganism is one or a mixture of bacillus licheniformis and bacillus subtilis.

Furthermore, the microbial washing sheet for washing tableware is mainly used for removing artificial dirt (containing beef tallow, vegetable oil, lard, wheat flour, milk powder, egg liquid, tomato sauce and mustard), oat stains, tea stains and the like.

According to the invention, bacillus licheniformis and/or bacillus subtilis are/is selected as an active agent, wherein the bacillus licheniformis has high propagation speed (10 ten thousand times of the bacillus licheniformis can be propagated in 4 hours), is strong in vitality, strong in acid resistance, strong in alkali resistance, high in oxygen resistance (aerobic propagation), low in oxygen resistance (anaerobic propagation) and the like, can quickly occupy space advantages through propagation, and can inhibit the growth and propagation of harmful bacteria; the reproduction speed of the bacillus subtilis is 8-12 times higher than that of other fungi; the strain has the characteristics of good stability, oxidation resistance, extrusion resistance, high temperature resistance and the like, can resist the high temperature of 60 ℃ for a long time, can survive for 20 minutes at the temperature of 120 ℃, and is the fungus with the best adaptability of the current beneficial microbial strains; the antibacterial agent can inhibit the growth and the propagation of other bacteria by quickly propagating and generating antibacterial substances, has excellent antibacterial performance, and is a completely nontoxic and pollution-free biological agent; the microorganism is in dormant state in tablet, and can be rapidly activated and proliferated after dissolving in water to rapidly decompose food residue on tableware.

In the invention, the polyethylene glycol 8000 is used as a tabletting auxiliary agent, so that the tablet is non-powdery and is not easy to break; the layer silicon is used as a buffering agent/corrosion inhibitor, so that dirt is loosened, emulsified and hydrolyzed, and the surface of the porcelain or stainless steel tableware is prevented from being corroded; the Marylac copolymer is used as a chelating agent/masking agent to soften water quality, so that no water stain is left on the tableware after washing is finished; the anhydrous sodium citrate is used as chelating agent/masking agent, and has water softening effect.

Compared with the prior art, the invention has the following beneficial effects:

1. excellent cleaning ability: the product can wash tableware with fermentation liquid formed by bacteria after dissolving tablet, and has high-efficiency elution and decomposition capability on vegetable oil, beef tallow, lard, protein stain, starch stain, etc. on tableware;

2. green and environment-friendly: the bacteria take the food residues as nutrient substances in the growth and propagation stages, so that the COD value of the restaurant wastewater can be reduced, and the discharge of the restaurant wastewater is reduced;

3. high-efficiency bacteriostasis: the bacteria in the product can inhibit the growth and reproduction of harmful bacteria on the surface of tableware in a biological competitive mode, so as to protect the health of human body;

4. the safety is high: the product has no strong alkaline/corrosive components, contains no phosphate and surfactant, can be completely biodegraded, has no toxicity to aquatic organisms, and has no influence on human bodies after being cleaned;

5. easy storage and long preservation time: the shelf life of the enzyme-containing cleaning products is generally 6-12 months, strict requirements are imposed on the storage environment, and the enzyme activity is gradually reduced along with the prolonging of the storage time; the activity of the bacillus licheniformis and the bacillus subtilis in the strain is not reduced along with the time extension, and the bacillus licheniformis and the bacillus subtilis can adapt to various adverse environments in a dormant state, thereby effectively solving the problems that the quality guarantee period of enzyme-containing products is short, and the enzyme-containing products are sensitive to temperature and acid-base environments and are difficult to store.
