Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a ceramic cooking utensil, and more specifically, for example, a method for manufacturing a cooking utensil for obtaining a ceramic pot body provided with a peeling layer on the inner surface to which food to be cooked does not adhere. This is related to.

In general, ceramic cookers are widely used because they have good fire circulation and heat the food to be cooked, but they have the disadvantage that if the food gets burnt, it is difficult to remove it.

SUMMARY OF THE INVENTION An object of the present invention is to overcome this drawback, and to provide a method for manufacturing a ceramic cooking utensil provided with a peeling layer from which burnt food can be easily peeled off.

Another object of the present invention is to use a safe resin that has good adhesion to ceramic surfaces and does not have a negative effect on the food to be cooked, so as to provide a peeling layer that can be easily removed from burnt food. An object of the present invention is to provide a method for manufacturing a ceramic cooker provided with the following.

Next, one embodiment of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a ceramic pot body formed and fired according to a predetermined composition, and has an annular handle 3 installed on the outer periphery of an opening 2.

Next, the inner surface 1A of the pot rest 1 and the upper surface 3A of the handle 3
A suitable surface roughening treatment such as sand blasting is applied to the treated surface to make it rough. Thereafter, a base treatment is performed on the rough surface by applying a base agent 4 containing a fluororesin such as a fluoroethylene primer as a component, and the applied base agent 4 is dried. Next, a release agent 5 containing fluororesin as a main component is applied onto the dried base material 4 and dried. Fluororesins used as components of base agents and release agents include tetrafluoroethylene resin, tetrafluoroethylene/hexafluoropropylene copolymer resin, trifluorochloroethylene resin, vinylidene fluoride resin, vinyl fluoride resin, etc. A material with physical properties that has excellent thermal stability and lubricity to which the food to be cooked does not easily adhere is used. The pan body 1 subjected to these treatments is then fired in a high-temperature atmosphere such as a firing pot, and the release agent 5 is baked onto the pan body 1 and the release layer 5 is bonded to the pan body 1.
A is formed. The primer used in this example is Fluon F27/4 (main component fluororesin: trade name) manufactured by Asahi Glass M.
was spray coated to a thickness of about 2 to 5 μIn and dried at 80°C. The release agent of this example was spray-coated with Fluon F2715 (main component: Fusso resin; trade name) manufactured by Asahi Glass, dried at 80°C,
At 0.degree. C., the adhesive was adhered and peeled off to a thickness of about 10 to 50 .mu.m. Baking is for example 30-60
After raising the temperature to 400℃ and holding it for about 3 to 10 minutes,
The temperature was gradually lowered to air temperature.

In this way, a pan body 1 was obtained in which the release layer 5 was provided on the inner surface 1A and the upper surface 3A of the handle portion 3. The release layer 5 was firmly adhered to the pan body 1, had a smooth surface, and had a beautiful appearance. The ceramic pot body 1 provided with the peeling layer 5 was used to heat and cook foods such as vegetables and meat, and the foods were cooked well.

The embodiment described above can be modified as follows.

In other words, (a) In addition to being made of ceramics, the pot body 1 can be made of ceramics such as earthenware, porcelain, and china, and its shape is not limited to the pot shape, but can also be made of ceramics of a predetermined shape. (b) Although a fluororesin-based base agent is used, the treatment of the base agent can be omitted and a release agent can be applied directly; (c) For forming a peel van. The baking temperature of the release agent can be changed depending on the type of fluororesin used, and (d) the release layer can be provided in the part of the cooker that comes into direct or solid contact with the food to be cooked. be.

As explained above, the present invention roughens the portion of ceramics for cooking that will become the cooking surface, and then applies a release agent containing fluororesin as a main component to the roughened surface. Since the release agent is baked and adhered to form a release layer that does not adhere to the food to be cooked, it is possible to obtain a ceramic cooking utensil provided with a release layer that does not adhere to the food to be cooked. That is, in the present invention, since the peeling layer is baked and adhered, the adhesion of the peeling layer is strong, and since the peeling ffi layer is made of fluororesin, the properties of the resin allow the food to be cooked to
'@ If it sticks to the surface, it can be easily removed. Since the release layer is mainly composed of fluororesin, it is convenient because it does not harm the G4 physical object during cooking.

Claims (1)

[Claims] A roughening treatment is applied to the part of the cooking pottery that will become the cooking surface, and then a peeling agent mainly composed of fluororesin is applied to the roughened surface. A method for manufacturing a ceramic cooking utensil, characterized by forming a peeling layer that does not adhere to the object to be cooked.
