Abstract
The invention relates to a baking plate for wafer or waffle bakers. The wafer or waffle baking surface of the baking plate is made of steel or cast iron by carving and is lastly processed as required. The baking plate is characterized in that the wafer or waffle baking surface is hardened by means of nitriding or carbonitriding and subsequent optional oxidation treatment.
Description
Technical field
The present invention relates to the bake plate for waffle or Waffle baking machine, the waffle of this bake plate or Waffle baking surface utilize steel or cast iron materials engraving to be shaped, and optionally carry out last processing processing.
Background technology
The baking machine of the above-mentioned type is used to food industry to produce soft waffle or crisp waffle.Described bake plate is normally toasted a part for pan, in order to toast soft waffle or crisp waffle, baking pan is movably, and it is heated to the baking vessel of baking temperature from starch adhesive or dough supply website process by means of transfer equipment, until the removal website of baked goods.The waffle of the type or Waffle baking machine have been the formerly technology of many decades.
After removal baked goods, the baking surface of described bake plate must be ready to again receive dough or starch adhesive at dough or starch adhesive supply website.
In the time that dough or starch adhesive or its residue hang over baking surface always, problem has produced, and its result is exactly: otherwise must clean baking surperficial, otherwise next baked goods can be destroyed.
Therefore occurred avoiding dough or starch adhesive or baking residue to be attached to the problem on the baking surface that bake plate assembles.In addition, also should realize be subsequently but necessary cleaning can try one's best and is performed simply, and do not damage waffle or Waffle baking is surperficial.
So far be known that with reducing the material adhering to and apply waffle or Waffle baking surface.For example, the known Teflon of using
material applies waffle or Waffle baking surface.But this coating has shortcoming, that is, in use it is vulnerable to wearing and tearing, and can be from baking surfacial spalling after the relative short time, and therefore described bake plate becomes and can not use.
Summary of the invention
According to bake plate of the present invention, its method according to this invention is configured, and has avoided above-mentioned all shortcomings.The object of the invention is by nitriding process or nitrocarburizing method and harden waffle or Waffle baking surface of subsequent oxidation processing alternatively.
The result of the sclerosis by nitriding process or nitrocarburizing method is exactly to have produced sclerosis and very level and smooth metal surface, and dough or starch adhesive or baking residue can not be attached on this metal surface.And, if contamination has appearred in metal surface, can remove easily, for example, brush scrubbing website.Surface to scrub be a kind of known cheap processing mode, from the angle of Machine Design, it wants in fact ratio to utilize as is known cleaning agent to wash and with the easier operational processes of post-drying.
Described bake plate material comprises steel or cast iron.Can use the cast iron of all known types.The cast iron of these types has the carbon content of about 2-5% and the silicone content of about 1-3%.Can add any alloying component and well-known composition in ironmaking technology.
Described steel is the steel alloy with a considerable number of alloying component, and described alloying component is different from carbon and generally comprises manganese, silicon, sulphur and the phosphorus of acceptable number.These alloys are used for advantageously affecting machinery and physical property.Low-alloy steel typically refers to the content of alloying element lower than 5%, and the content of those alloying elements is higher than 5% the high-alloy steel that is called.Stainless steel normally has the ferroalloy of at least 10.05% chromium component.Pure carbon steel is mainly made up of iron and carbon conventionally, and wherein the maximum level of carbon is 2%, and those additives except adding for deoxidation, only has a small amount of other compositions to exist, wherein silicone content be conventionally limited to 0.6% and manganese content be limited to 1.65%.
Generally speaking, all steel and iron can use, and it has formed the major part that the mass fraction with a large amount of metallic bond characteristics and iron is greater than 50% setting material.
In practice, for example, from the sclerosis of gear, known cure process needs considerable time.This comprises nitriding process, nitrocarburizing method and the nitrocarburizing method with subsequent oxidation.Due to these treatment steps, on metal surface, form at least base closed layer with high ceramic characteristics.Due to the increase of the mass fraction of the metal ingredient of described material and the nitrogen of nitrogen and/or carbon and possible carbon compound, this layer forms ceramic characteristics approaching in surperficial volume.
For nitrocarburizing method, ready bake plate (waffle or the Waffle baking surface that are provided with the engraving of expectation for example complete by polishing alternatively) is sent to nitrocarburizing smelting furnace.For nitrocarburizing method, carbon donor, for example, carbon dioxide or so-called exogas or cracked gas, be temporarily provided in furnace gas environment continuously.These known gases are detained to act at elevated temperatures the described surface long duration.Action time is between 0.5 hour and 10 hours, and temperature changes between 400 degrees Celsius and 800 degrees Celsius.
In addition, nitriding step also can be carried out by glow discharge nitriding, and wherein nitrogen is as being provided for nitrogen body.In this case, workpiece is connected to negative electrode and smelting furnace side reaction wall is connected on anode.Described furnace chamber is evacuated to the voltage that is less than 10 millibars and applies a hundreds of volt between anode and negative electrode.And have about 10 amperes current strength constant or pulse direct current next-door neighbour surface of the work place produce glow discharge.
(also carrying out oxidation step after described step) during nitrocarburizing, to toast on surperficial metal material and harden, this sclerosis is preferably deep to the degree of depth that is greater than 0.05 millimeter, preferably in the degree of depth of 0.2-0.3 millimeter.
Brief description of the drawings
Fig. 1 shows the baking surface of the bake plate of one embodiment of the invention.
Detailed description of the invention
With reference to Fig. 1, be for example that the bake plate 1 of the bottom of baking pan has eight Waffles baking surfaces 2 of total in surface thereon, at starch adhesive supply website, liquid starch adhesive is poured in described baking surface for toasting soft waffle.Closing described baking pan and after baking vessel, the soft waffle after baking is transported to starch adhesive supply website again by removal and described baking pan.
