Carbonization treatment method for Teflon coating in food mold

Abstract

The invention discloses a carbonization treatment method for a Teflon coating in a food mold. A set temperature limit value is adopted for controlling carbonization of a Teflon material without damaging a plate of the mold, and the limit value is lower than the melting point temperature value of the plate of the mold and higher than the melting point temperature value of the Teflon material. Compared with the prior art, the treatment method has the advantages that operation is easy, the high-temperature carbonization effect is good, a Teflon material coating remaining on the inner wall of the mold can be easily and thoroughly removed, and the treatment process has no damage to the inner wall of the mold, no waste gas emission, no pollution and no noise; and the method is very environmentally friendly, the mold is really recycled, the production cost is reduced for food enterprises, and the mold is very suitable for being popularized and used.

Description

technical field [0001] The invention belongs to the technical field of coating removal, and specifically relates to a carbonization treatment method for Teflon in food molds. Background technique [0002] In the mass production process of bread, aluminum alloy molds are usually used for baking and forming; therefore, during the baking and forming process of bread, the bread material is very easy to stick to the inner wall of the aluminum alloy mold, so people have developed Teflon After the Teflon material is coated on the inner wall of the mold, it can solve the problem of the surface of the bread being adhered to. However, after the mold with the Teflon coating has been used for a period of time, the Teflon coating will fall off. After the coating peels off, when the bread mold is baked and the bread is demoulded, the phenomenon of bread sticking occurs, resulting in potholes and unevenness on the surface of the bread, which affects the appearance of the bread; in view of ...

[0002] In the mass production process of bread, aluminum alloy molds are usually used for baking and forming; therefore, during the baking and forming process of bread, the bread material is very easy to stick to the inner wall of the aluminum alloy mold, so people have developed Teflon After the Teflon material is coated on the inner wall of the mold, it can solve the problem of the surface of the bread being adhered to. However, after the mold with the Teflon coating has been used for a period of time, the Teflon coating will fall off. After the coating peels off, when the bread mold is baked and the bread is demoulded, the phenomenon of bread sticking occurs, resulting in potholes and unevenness on the surface of the bread, which affects the appearance of the bread; in view of this phenomenon, the current more traditional solutions are: 1 1. For the part of the mold that has fallen off the coating, the old coating that remains on the inner wall of the mold is removed by sandblasting, and a new Teflon coating is sprayed again; this method has a very labor-intensive manual grinding, a long grinding time, and Environmental pollution and noise pollution; it will even destroy the thickness of the inner wall of the mold, and the effect is very unsatisfactory; 2. Directly scrap the old mold and buy a new mold, resulting in waste of mold materials and greatly increasing the production cost of food companies
