Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a focusing machine used in the process of manufacturing processed foods.

[Prior Art] In the process of manufacturing a large amount of processed food, after a certain amount of cooking, only a step of making a brown mark, which is a part of the process of cooking food, may be performed as a finishing step.

In a conventional device for making a brown mark on food, heating is performed by using an electric heater, a gas burner, or the like.

Here, in the process of browning food materials, a device that applies a uniform high heat load to a wide area as much as possible in a short time is required.

[Problems to be solved by the invention] However, it is difficult to obtain a uniform heating state with a high heat load in a conventional device using an electric heater or a gas burner. There is a problem that unevenness occurs.

For this reason, in the actual work process, it is necessary to reduce the heat load and lengthen the heating time to give a uniform browning, or to place the foodstuffs in a relatively narrow area to perform the work. However, there is a problem that it takes a relatively long time to make a uniform brown on all the ingredients, and the working time cannot be shortened.

On the other hand, in the process of browning the food, it may be necessary to turn over the food in order to brown the entire surface of the food, and conventional equipment requires equipment for that process. There is.

Further, since the conventional electric heater and gas burner are arranged in parallel with the flat surface of the food material placing table, the temperature distribution condition is different between the central portion and both ends of the food material placing table, and a large amount of food material is processed. There is also a problem that unevenness occurs between individual foodstuffs depending on the position where the food is placed.

Therefore, an object of the present invention is to solve the above problems and to provide an apparatus capable of uniformly browning the entire surface of food in a short time.

[Means for Solving the Problems] In order to achieve the above object, a food graining machine according to the present invention is an iron plate-shaped foodstuff placing portion on which foodstuffs are placed, and a longitudinal direction of the foodstuff placing portion. A plurality of surface combustion type burners arranged in parallel, and having an exhaust portion at a predetermined position, and an external cover portion that covers the burner portion from the outside, in the food graining machine, the surface combustion type burner, The surface combustion type high radiation burner is provided with a high radiation burner plate made of a fiber sintered plate having a porosity of 80% or more and having uniformly fine voids over the entire surface.

Furthermore, the iron plate-shaped food material placing portion is made of a conveyor-like member, and the outer cover portion has a tunnel-like structure that allows passage of the food material arranging portion. A preheating means for heating the mounting portion is provided.

[Operation] Since the present invention is configured as described above, the high radiant heat of the surface combustion type high radiant burner can be used to impart uniform browning to the food material in a short time. Further, since the plurality of burners are arranged in parallel with the longitudinal direction of the food material placing portion, it is possible to maintain a uniform temperature distribution condition over the entire surface of the food material placing portion.

Here, in the present invention, since the high radiant heat of the burner is efficiently used, the outer cover portion prevents the radiant heat from escaping. Further, by providing an appropriate exhaust part in the outer cover part, it is possible to effectively utilize convection of radiant heat and the like, and it is possible to perform a more effective and short-time browning operation.

Moreover, in the invention described in claim (2) of the present application, a large amount of foodstuffs can be continuously processed in a short time by the food placing portion of the conveyor-shaped member.

On the other hand, in this invention, since the preheating means is provided in the iron plate-shaped food material placing portion, the food material is heated in the food material placing portion itself.

Therefore, the back side of the food can be browned, and the entire surface of the food can be browned in a short time.

Here, the surface combustion type high radiant burner is provided with a burner plate of the surface combustion type which has been developed in recent years. In such a burner plate, the present invention is a burning part of the burner utilizing radiant energy. 80 porosity as burner plate
% Fiber sintered plate is used. The fibers used in this fiber sintered plate have a diameter of 10 μm to 50 μm and a length of
Fibers of 10 mm to 100 mm and made of metal or ceramics are preferable. Moreover, the thickness of this fiber sintered plate is 2 mm to 5 mm.
It is preferably about mm. In the present invention, by using such a burner plate, it is possible to obtain a surface combustion type high radiation burner which burns in a state where the flame from the surface does not float and adheres to the surface.

This is because the above fiber sintered plate has such a high porosity, so that the maximum burning amount per unit area is 80 KcaL / cm ² · h.
This is because it is possible to perform high-load combustion of a certain degree. Further, since the burner plate has uniformly fine voids over its entire surface, there is an advantage that the surface temperature is kept uniform. On the other hand, by limiting the plate thickness to a certain width, it is possible to prevent flashback during combustion and increase ventilation resistance.

Hereinafter, the present invention will be described in more detail through examples.

[Embodiment] FIGS. 1 and 2 show a food browning machine according to an embodiment of the present invention. In the figure, an iron plate caterpillar-shaped conveyor 3 laid in the lower frame 17 is driven by a motor 7 in the direction of the arrow. This drive speed is adjusted by the controller 18.

A burner unit 5 in which the upper burner 1 is inscribed is provided above the lower frame 17,
A preheating burner 2 for preheating the food before placing it on the conveyor 3 is provided in the lower part of the.

The preheating burner 2 may not be the surface combustion type high radiation burner.

Further, an oil coating device 15 is provided at the feeding portion of the conveyor 3 to prevent the food material from sticking to the conveyor 3. Further, a feeding roller is provided at the feeding portion of the conveyor 3.

Here, the upper burner 1 of the present embodiment is provided substantially radially in parallel with the conveyor 3 so as to cover the upper portion of the conveyor 3 (see FIG. 2), and is covered with the burner unit 5 and its outer peripheral cover. It has a tunnel structure that surrounds the food material placing portion of the conveyor 3.

Further, the burner unit 5 is provided with an upper exhaust part 18 and a lateral exhaust part 19, which can be opened and closed arbitrarily.
Further, the arrangement of each of the upper burners 1 can be selectively changed. As a result, optimum processing can be performed by appropriately changing the setting conditions depending on the output of each burner, the feeding speed of the conveyor 3, and various conditions such as the material of the food material, the size, and the degree of processing.

Next, an example of the browning process using this embodiment will be described with reference to FIG.

Here, when the roast beef using block meat is browned, the processing time until the entire surface of the food material is uniformly browned is measured. In addition, actually, the time from the surface layer to the state where the depth is about 2 to 3 mm and the surface is browned is measured.

First, FIG. 3 shows a state in which the upper exhaust portion is closed. When the conveyor 3 is preheated to 300 ° C. by the preheating burner, the browning operation is performed. Then, it became a state with even browning.

That is, the uniform browning process is completed in a dramatically shorter time than the conventional example.

Further, in this embodiment, since the surface combustion type high radiant burner plate made of the fiber sintered plate is used, the processing by the high load radiant heat is performed, so that the burns on the food surface are uniform and uniform. It was in a state.

Furthermore, due to the difference in the placement position of the foodstuffs on the conveyor 3,
The state of browning between the ingredients was also uniform.

On the other hand, the back surface of the food material is also uniformly browned by being heated by the iron plate-shaped conveyer 3, so that it is not necessary to turn over the food material.
