Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food sterilizer, and more particularly to a food sterilizer that enables heat sterilization without impairing the flavor of raw vegetables and the like.
[0002]
[Prior art]
In recent years, raw vegetables are served as salads and the like in dishes served at restaurants and the like. As a procedure for cooking these raw vegetables, they are cut after being washed with water and decorated in a cooked product.
[0003]
However, since the food poisoning incident caused by O-157 bacteria has occurred, the ingredients have been washed with chemicals such as hypochlorous acid water before being put out for cooking, but recent environmental pollution problems have been regarded as important. As it comes to be used, it is no longer allowed to drain the used chemical water after cleaning the ingredients into the sewer as it is, and there is a new problem that it must be drained after being neutralized.
[0004]
Instead of sterilizing with such chemicals, if the food is soaked in hot water and treated with bacteria, environmental problems can be prevented from being adversely affected. However, since the ingredients are boiled in boiling treatment with hot water, the original flavor is lost in raw vegetables and the like, and there is a disadvantage that it becomes crunchy.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a food sterilizer that can solve the above-described conventional problems and can heat and sterilize foods such as raw vegetables without losing the flavor.

[0025]
The above-described sterilizing apparatus of the present invention is mainly suitable for sterilizing raw vegetables, but can also be used for sterilizing foods other than raw vegetables. Moreover, although the sterilization processing machine of this invention is used for the process of the fungi adhering to the surface of a foodstuff, it can be used also for steam cooking by performing the steam process for a long time.
[0026]
Hereinafter, the effect | action which sterilizes a foodstuff with the said sterilization processing machine is demonstrated.
First, after the storage drum 2 is rotated on the support 4 in a state of being carried out of the heating chamber 3 and the position of the door 8 is moved upward, the door 8 is opened at that position. The food is put into the storage drum 2 from the opened opening. The amount of ingredients to be charged is such that there is sufficient space in the storage drum 2 and the ingredients are stirred while freely floating in the air. When the food material is put into the storage drum 2 in this way, the open / close door 8 is closed again.
[0027]
On the other hand, in the heating chamber 3, the door 13 is closed, steam is ejected from the steam pipe 14 into the heating chamber 12, the inside of the heating chamber 12 is heated to a preset temperature, and is substantially constant by a temperature sensor (not shown). Maintain temperature. Next, the storage drum 2 storing the ingredients as described above is moved together with the support 4 and is carried into the heating chamber 12 of the heating chamber 3, and further driven on the driven shaft 9 and the heating chamber 3 side of the storage drum 2. The drive shaft 11 of the motor 10 is connected, and the door 13 is further closed to make the heating chamber 12 sealed.
[0028]
Next, while the storage drum 2 is rotated by the drive motor 10, the storage drum 2 is heated by steam ejected from the steam pipe 14. The rotational speed of the storage drum 2 is set such that the centrifugal force is not applied to the food material, and the food material is broken apart while being separated, and depending on the food material, a part of the food drum is flying in the air. While maintaining this disjoint state, contact with the vapor entering the storage drum 2 from the porous wall 5 provides better heat conduction efficiency than dry heated air, and quickly heats the food in a short time. And can be sterilized. Since the food material thus obtained is heated for a short time, many water droplets do not adhere to the surface.
[0029]
When the heat treatment is completed, the rotation of the storage drum 2 is stopped and the injection of steam from the steam pipe 14 is stopped. Then, the door 13 of the heating chamber 3 is opened, and the storage drum 2 is carried out of the heating chamber 3 together with the support 4. To do. The receiving rod 17 is placed on the lower frame 4b of the support base 4 carried out to the outside, and the storage drum 2 is rotated so that the door 8 stops at the lower position, and then the door 8 is opened. By opening the door 8, the sterilized food material falls from the storage drum 2 into the receiving bowl 17 and is collected.
[0030]
【The invention's effect】
As described above, according to the present invention, since the storage drum storing the food is heat-treated with steam while being driven to rotate in the heating chamber, the steam entering from the porous wall while keeping the food separated and separated from each other. It is possible to heat-treat the entire surface in a short time without drying the surface of the food. Therefore, heat sterilization can be performed without substantially impairing the flavor of the foodstuff.
