Description

[Detailed Description of the Invention] The industrial invention is used to neutralize 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 rinse agent composition.

In the kitchens of hotels, restaurants, etc., heating cookers called flight ranges and griddle top ranges are used. these are.

This is a cooking utensil for cooking meat, fish, vegetables, etc. on a cast iron plate with a thin layer of oil applied, usually at a temperature of 150 to 250℃.
It is used in a temperature range of about

These ranges are constantly heated, so if they become dirty due to oil stains, burnt food, etc. during business hours, it is necessary to remove and clean them without stopping heating, especially in restaurants that are open 24 hours a day. This is an important issue in such cases. 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 since it requires a lot of force, the worker's hands and fingers may come into contact with the heated plate, and the oil may scatter. There were problems such as causing burn accidents.

Furthermore, in the field of cleaning oil stains from hard surfaces, alkaline cleaning agents with good cleaning power are generally used. However, when using an alkaline cleaning agent, it is necessary to remove the alkaline content remaining on the iron plate after cleaning, so repeated washing with water or a neutralized hydrous liquid acidic rinse agent is used. However, this caused the temperature of the hot iron plates to drop, resulting in energy loss and temporary suspension of business operations.

In addition, when a water-containing liquid acidic rinse agent is sprinkled on a hot iron plate,
There was a problem in that the water was heated and rapidly evaporated and scattered, and the ingredients in the rinse agent and residual alkaline agents adhered to the skin, causing ``itching.''

The present invention is capable of neutralizing residual alkaline content in a small amount in a short time by preventing a drop in the temperature of the iron plate after cleaning stains on a hot cooking iron plate with an alkaline cleaning agent. , provides a rinse agent composition that causes less skin irritation.

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

(a) Long chain fatty acid having 8 to 20 carbon atoms.

(b) Nonionic organic compound.

The present invention will be explained in more detail below.

The long-chain fatty acids C, ~C2 are decomposed by peeling off the oil stain layer from the hot iron plate with an alkaline detergent, lifting it up, and decomposing it.
It is possible to quickly neutralize the alkaline content that remains after being easily removed with a hot iron plate, etc., and to suppress the temperature drop of the hot iron plate by avoiding washing with water as much as possible. Moreover, even if there is any scraping or wiping residue after rinsing, there is little danger in terms of hygiene.

Such C, -C,. Specific examples of long chain fatty acids include caprylic acid, capric acid, lauric acid, myristic acid, stearic acid, oleic acid, coconut fatty acid, tallow fatty acid, hydroxylauric acid, aminolauric acid, etc. Alternatively, they can be used in combination.

The amount of C8 to C2° long chain fatty acids to be incorporated into the rinse agent composition is determined from the viewpoints of rinsing effect, workability, and finish quality.
2 to 80% by weight is suitable, preferably 5 to 60% by weight.

When used, the nonionic organic compound quickly spreads the acidic substance on the hot iron plate without rapidly evaporating or scattering on the hot iron plate like water. Therefore, non-ionic organic compounds do not easily decompose or evaporate or scatter on a hot iron plate at 100 to 250 degrees Celsius, and are easily compatible with oil, so even if they remain and get mixed into cooked products. Specific examples of such nonionic organic compounds, which are preferably less hazardous to hygiene, include soybean oil, palm oil,
These include fats and oils such as rapeseed oil and beef tallow, hydrocarbons such as liquid paraffin and solid paraffin, polyols such as polyethylene glycol and polypropylene glycol, and nonionic surfactants, which may be used alone or in combination. It is used as

The blending amount of the nonionic organic compound in the rinse agent composition is 20% from the viewpoint of rinsing effect 1 workability and finish quality.
~98% by weight is suitable, preferably 40-95% by weight.

The rinse agent composition of the present invention is preferably a non-aqueous rinse agent that does not contain water substantially, but may contain a small amount of water as long as the effects of the present invention are not impaired.

According to the rinse agent composition of the present invention, by combining a C8-C2° long-chain fatty acid and a nonionic organic compound, the rinse agent composition of the present invention can be rapidly removed on an iron plate like when water is used as a medium. It does not evaporate and scatter, and is quickly neutralized.

Further, the temperature of the hot iron plate is prevented from decreasing due to evaporation of water. Therefore, the workability is good because the skin is not irritated by evaporation and scattering, and moreover, 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 with reference to Examples, but prior to this, the evaluation method used in the Examples will be described.

(1) Rinseability and hot iron plate temperature reduction After cleaning the oil stains on one iron plate 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, the amount of rinse agent composition required for neutralization is determined and evaluated in the following three stages. This end point is determined using Lidmus test strips.

The temperature drop at this time is also measured.

Sugi's base' o: Neutralization ends below soog.

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.

X: It evaporates and the skin is itchy.

A rinsing agent composition of the composition shown in Table 1 below was prepared by the Shi-Oichi group, and its rinsing properties, hot iron plate temperature reduction, and evaporation properties were evaluated, and the results are shown in Table 1. However, sample Nα9 is a conventional water-containing liquid acidic rinse agent composition, and sample Na1O is only water.
