Description

[Detailed Description of the Invention] The present invention is for neutralizing the alkaline content after cleaning the stains on high-temperature cooking iron plates used in the kitchens of hotels, restaurants, etc. with an alkaline cleaning agent. The present invention relates to a solid rinse agent composition for use.

[Also] In the kitchens of hotels, restaurants, etc., heating cookers called flight ranges and griddle top ranges are used. These are cooking utensils for cooking meat, fish, vegetables, etc. by applying oil on cast iron plates, and are usually used at a temperature range of about 150 to 250°C.

These ranges are constantly heated, so if oil stains, burnt spots, etc. occur during operation, it is necessary to remove and clean them without stopping heating, especially when open 24 hours a day. This is an important problem in 1-run and the like. Conventionally, in such cases, a type of grindstone called a griddle stone was used to remove the dirt by sprinkling cooking oil on it. However, it takes a lot of effort and time to scrape it off with a whetstone, and it also requires a lot of force to scrape it off.
There were problems such as the worker's hands, fingers, etc. coming into contact with the heated plate due to excessive force, and the oil scattering causing burns.

Furthermore, in the field of cleaning oil stains from hard surfaces, alkaline cleaning agents with good cleaning power are generally used. However, when an alkaline cleaning agent is used, it is necessary to remove the alkaline content remaining on the iron plate after cleaning, which requires repeated washing with water or the use of a neutralizing liquid rinse agent. As a result, the temperature of the hot iron plates dropped, causing energy loss and temporary suspension of business operations.

In addition, when a liquid acidic rinse agent is sprinkled on a hot iron plate, the moisture is heated and evaporates rapidly, causing it to scatter, causing the components and residual alkaline agent in the rinse agent to adhere to the skin and cause itching. Ta.

The present invention is capable of neutralizing residual alkaline content in a small amount and in a short time by preventing the temperature of the iron plate from decreasing after cleaning the dirt on a hot cooking iron plate with an alkaline detergent, and at the same time neutralizing the alkaline content that remains on the hot cooking iron plate in a short time. The present invention provides a solid rinse agent composition that is less irritating.

The rinse agent composition for high-temperature cooking iron plates of the present invention comprises the following (a)
) and (b).

(a) A nonionic organic compound that is solid at room temperature.

(b) Acidic substances.

The present invention will be explained in more detail below.

When used, a nonionic organic compound that is solid at room temperature rapidly evaporates and melts on a hot iron plate like water, without scattering, and quickly spreads acidic substances on the hot iron plate. Therefore, non-ionic organic compounds that are solid at room temperature melt easily on a hot iron plate at 100 to 250 degrees Celsius without decomposing, evaporating, or scattering. It is preferable to use a substance that poses little hygiene risk even if it may be mixed with the water.

Specific examples of such organic compounds include higher alcohols that are solid at room temperature, polyethylene glycol, polyoxyethylene higher aliphatic alcohols (polyoxyethylene adducts of higher aliphatic alcohols), hydrocarbons, oils and fats, etc. These may be used alone or in combination.

The amount of the nonionic organic compound that is solid at room temperature added to the rinse agent composition is preferably 5 to 80% by weight, preferably 10 to 80% by weight, from the viewpoint of rinsing effect, workability, and manufacturability.
It is 60% by weight.

As an acidic substance, an alkaline cleaning agent can be used to remove the oil stain layer from the hot iron plate, lift it up, decompose it, and quickly neutralize the remaining alkali-potassium content after it is easily removed with a turner, etc. It is preferable that washing with water can be avoided as much as possible in order to suppress a drop in temperature, and even if there is any residue left after rinsing, it is required that there is little danger from a hygienic point of view. Specific examples of such acidic substances include organic carboxylic acids such as lactic acid, citric acid, malic acid, tartaric acid, gluconic acid, succinic acid, fumaric acid, and acetic acid; Examples include phosphoric acid, polyphosphoric acid, and alkali metal salts of acidic polyphosphates. These acidic substances can be used alone or in combination.

The amount of the acidic substance in the rinse agent composition is 5 to 80% by weight from the same viewpoint as the nonionic organic compound described above.
is suitable, preferably 10 to 60% by weight.

The rinse agent composition of the present invention may contain other optional components in addition to the above-mentioned essential components, if necessary. Examples of such optional components include polyols that are liquid at room temperature such as glycerin, polyglycerin, sorbitol, ethylene glycol, and propylene glycol, and pigments. These polyols quickly spread acidic substances on the hot iron plate when a nonionic organic compound that is solid at room temperature is melted on the hot iron plate, making neutralization more efficient.

The cleaning composition of the present invention can be obtained by mixing and integrating the above-mentioned components and molding the mixture into an appropriate shape such as granules, sheets, sticks, etc. For example, a nonionic organic compound that is solid at room temperature is melted to a temperature above its melting point, the other components are sequentially added while stirring to uniformly disperse the compound, and then the temperature is lowered to below the melting point of the nonionic organic compound. extrusion,
It is obtained as granules by granulation using methods such as stirring and crushing. It can also be obtained by spray cooling a uniformly dispersed product.

In addition, according to the rinse agent composition of the present invention, by combining a nonionic organic compound that is solid at room temperature and an acidic substance, it can be rapidly evaporated on an iron plate like when water is used as a medium. The nonionic organic compound quickly melts without scattering, and the acidic substance spreads on the hot iron plate, neutralizing it. It also prevents the temperature of the hot iron plate from dropping due to water evaporation. be done. Therefore, the workability is good because the skin is not irritated by evaporation or scattering, and the alkaline content remaining after cleaning with an alkaline detergent can be neutralized in a short time with a small amount of rinsing agent.

Hereinafter, the effects of the present invention will be specifically explained using examples, but first, the evaluation method used in the examples will be described.

(1) Rinseability and hot iron plate temperature reduction After cleaning the oil stains on the iron plate 1 at 195-200℃ with 1000g of alkaline detergent containing 20% sodium hydroxide and removing it with a turner, rinse agent composition Neutralize with things.

At this time, find the rinse agent composition required for neutralization and use the following three methods.
Evaluate in stages. This end point is determined using Lidmus test strips.

In addition, the temperature drop at this time is also 11 in total.

Rinseability evaluation criteria ○: Neutralization is completed at 500 g or less.

Δ: Neutralization is completed at 500 to 2000 g.

X: Neutralization ends at 2000g or more.

(2) Evaluation method for evaporation The evaporation state when the rinse agent composition is sprayed on a hot iron plate is evaluated in three stages.

O: hardly evaporates.

Δ: Evaporation occurs and the skin is slightly itchy.

×: Evaporation causes pain and itching on the skin.

Granular rinse agent compositions having the compositions shown in Tai-ryu Consistent Postscript-1 were prepared, and the rinsing properties, hot iron plate temperature reduction, and evaporation properties were evaluated, and the results are shown in Table-1. However, sample Nα
10 is a liquid rinse composition and sample NαII is a control (water only).
