Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for automatically producing rice bran in the food industry.

(Conventional technology) Nukazuke is pickled vegetables and fish in rice bran.

The rice bran bed used for rice bran is mainly made of rice bran with small amounts of dried sardines, bonito flakes, kelp, etc. added, water, salt, mustard, etc., or even seeds, mixed and left to stand until yeast and a small amount of lactic acid bacteria are added. It happens when it happens.

In order to keep these fungi alive, the rice bran bed is stirred by hand several times a day, and if you manage it carefully, you can obtain a delicious rice bran paste.

(Problem to be solved by the invention) However, recently it has become physically impossible to carefully manage the rice bran floor. If the environmental conditions are bad, the rice bran floor will rot and become useless. The environmental conditions of the rice bran bed are influenced by temperature, oxygen supply, stirring, etc. The purpose of the present invention is to enable anyone to easily and deliciously pickle rice bran pickles.

(Means for Solving the Problems) The present invention provides an automatic pickled rice bran production machine that manages the environmental conditions of the rice bran bed and automatically produces rice bran rice bran under optimal conditions.

To this end, the present invention provides a container for accommodating rice bran beds and pickles, a temperature control device for keeping the temperature inside the container constant, an oxygen supply device for supplying oxygen-containing gas into the container, and a stirring device for stirring the contents of the container. The invention is characterized by having a stirring device for controlling the operation of each device, and a control device for monitoring and controlling the operation of each device.

The shape, material, etc. of the container for storing rice bran and pickles such as vegetables and fish are not limited, but stainless steel or plastic is preferably used to prevent acid corrosion. Alternatively, the container may be double-layered, and the inner container may be removable so that pickles can be easily taken out and put in the container.

In this case, it is preferable that the inner container be made of a basket so that the rice bran bed can be taken out and put in freely.

The temperature control device maintains a constant temperature within the container. For heating, a heat source such as electricity or gas can be used, and for cooling, a small refrigerator or an electronic thermoelement can be used. The temperature is 5
Set between ° and 30 °C. When the temperature rises above 30°C, fungi such as lactic acid bacteria grow abnormally, resulting in so-called "sour" pickles. When the temperature drops below 5°C, the activities of yeast, lactic acid bacteria, and other fungi almost cease, and the amount of oxygen required decreases, making it difficult to make pickles. In particular, the appropriate temperature for pickles is 1.
Since the temperature is 3° to 18°C, it is preferable to adjust the temperature within this range.

The oxygen supply device supplies a gas containing oxygen into the container. Oxygen, along with temperature, is an important element in nukazuke, and cannot be considered separately from temperature.

The reason why the rice bran bed is stirred is to supply oxygen, and when there is a lot of oxygen, yeast and lactic acid bacteria become more active. In addition, if there is insufficient oxygen supply, other anaerobic bacteria will occur, causing the rice bran bed to rot. At this time, when COz abnormally occurs, the so-called "armpit phenomenon" occurs, where the floor becomes fluffy and rots.
The floor is completely ruined. Oxygen can be used in either pure or airborne form and is supplied into the container through a sterile filter via a conduit, opening, etc. Since the bran bed is a water-like fluid, a circulation type that supplies oxygen using the ejector principle or an aeration type that supplies air in the form of bubbles from the bottom of the container can be used.

The stirring device forcibly stirs the rice bran in the container.

At that time, it is preferable not to stir the pickled vegetables or the like. When the rice bran bed is stirred, it is replenished with oxygen and maintained in good environmental conditions. This stirring device can also be used as an oxygen supply device. If the oxygen supply device is a method that forcibly blows oxygen or air into the container, the rice bran bed is forcibly circulated using a slurry pump, near compressor, etc. at the same time as oxygen is supplied. It is also possible to carry out replenishment and stirring of the rice bran bed at the same time. When using such a circulation system, a temperature control device may be incorporated to perform cooling and heating during the circulation process.

The control device monitors and controls the operation of each of the devices.

The temperature, oxygen concentration, etc. inside the container are monitored, and if they are out of the appropriate range, the temperature control device and oxygen supply device are activated to control them to appropriate values. Further, the stirring time is set so that the stirring device is operated at regular intervals. The control device can be combined with means for monitoring and controlling not only the temperature and oxygen concentration but also the concentration of salt and moisture in the rice bran bed, the type and concentration of fungi, and the like. It is also possible to set a time for the pickles to clear, and to stop the operation of each device when the pickles are finished, or to notify the pickle with a buzzer, lamp, etc. As a control device, a microcomputer can be incorporated. Temperature, oxygen concentration, pickling time, etc. can be set based on experience based on the type, amount, size, salt concentration, etc. of vegetables, etc.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

As shown in FIG. 1, the rice bran pickle automatic manufacturing machine 1 of the present invention includes:
The container consists of an outer container 2, an inner container 3, a mesh container 4, and a lid 5. A temperature control device consisting of a heating heater 6 and a cooling coil 8 connected to a cooling compressor 7 is provided outside the inner container 3 .

A near compressor 10 equipped with a sterile filter 9 is provided to supply gas containing oxygen into the container, and the gas is supplied into the container through a diffuser plate 11 provided at the bottom of the inner container 3. 12 is a handle of the lid 5.

(Example) Comparative Example First, as a comparative example, rice bran pickles were made using a conventional method. For this purpose, we used rice bran bed, which is stirred several times a day during the winter to make it taste better.

At an ambient temperature of 13 to 15 °C of the container containing the rice bran bed, put 3 kg of the rice bran bed with a moisture content of 80% and a salt concentration of 3% into a container with a capacity of 51, and maintain the temperature of the rice bran bed at 25 °C.
I tested it by stirring it evenly by hand once a day. The results are shown below.

Using the automatic rice bran pickle making machine according to the present invention shown in the drawing of Example Contents 51, the temperature inside the container was adjusted to 25° C. using 100 V household electricity as a heat source. A slurry pump (not shown in the figure) was used as the stirring device. Temperature and agitation were controlled by a thermostat and timer (not shown).

Using the bran bed and pickles under the same conditions as in Comparative Example 1, a rot test of the bran bed was conducted in the same manner. Stirred 12 times per day for 3 minutes each at a pump volume of 181 per minute. Gas supply rate is 10.8 per minute
It was 1.

In the 7-day test, the appearance of the Nuka floor, the softness of the floor,
No change was observed in the taste of the pickles.

(Effect of the invention) According to the invention, the temperature, oxygen concentration, etc. of the rice bran bed are adjusted,
Since each device for stirring the rice bran bed is provided, the environmental conditions of the rice bran bed can be maintained optimally.

Furthermore, since a control device is installed to monitor and control each device, pickling in rice bran can be done automatically and mechanically. The manufacturing machine of the present invention can be used not only for home use but also for commercial use by increasing the size of the container, and it is also possible to mass-produce rice bran pickles.
