Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a measuring rice jug that changes the moisture content of rice during storage and preservation to achieve an optimum moisture content, and that constantly supplies rice with a constant moisture content during cooking. be.

Technique of Jumai The measuring rice bin of Jumai consists of a water container 21 as shown in Figure 2.
It was only equipped with a measuring device 22 on the bottom of the water container, and did not measure the moisture content of the rice in the water container and change it to the optimum moisture content.

Problems to be Solved by the Invention Rice measuring bins for rice are used to store and measure rice, and they lack consideration for rice quality, such as conditioning rice to maintain a constant moisture content. Met. In recent years, efforts have been made to save labor in rice cultivation, and the mechanization of rice drying has progressed further, with hot air drying using dryers becoming commonplace. Drying rice using a dryer causes variations in the drying state, and if an attempt is made to dry the rice to a moisture content of 16% or less, the rice often ends up in an overdried state with a moisture content of 11 to 12%. Over-drying is not a problem in rice inspection and acceptance inspection, and when rice is polished and cooked by consumers, over-dried rice is
This has caused problems such as ``not being able to cook rice with the same amount of water'' and ``the rice tastes bad.''

In addition, it was necessary to adjust the amount of water each time the rice was cooked by using less water for new rice and more water for old rice. Furthermore, during the rainy season, there is a lot of humidity in the air, which supplies a lot of moisture to the stored rice, which increases the moisture content, causing the rice to become too soft and taste bad when cooked.

In view of these problems, the present invention aims to provide a measuring rice jug that can constantly adjust the moisture content of rice in a water container to an optimum moisture content and supply rice with a uniform moisture content. This is the purpose.

Means for Solving the Problems In order to solve the above problems, the measuring rice jug of the present invention includes a box-shaped water container, a rice measuring device provided on the bottom of the water container, and a rice measuring device in the water container. It is equipped with a sensor that measures the moisture content and a humidifier that changes the moisture content of rice.

The sensor for measuring the moisture content of the rice is installed so as to protrude into the water container, so as to detect the temperature and humidity of the rice in the water container.

In addition, the sensor that measures the moisture content of rice places electrodes facing each other in a water container, applies a small voltage between the electrodes, detects the amount of current flowing between the electrodes and the temperature of the rice, and measures the moisture content. I try to do that.

The humidifying device has a water container and a heater, and a humidifying steam outlet is provided in the water container above the maximum rice storage position.

In addition, a heating section for dehumidification is installed on the bottom of the water container to humidify and
It allows for dehumidification.

In addition, a moisture percentage display device is installed on the outer surface of the water container to display the moisture percentage of rice, and near this moisture percentage display device,
A humidifier, a heating section for dehumidification, and an operating section for opening and closing the moisture content display device are provided.

Furthermore, the present invention is provided with a moisture percentage display device that normally displays the time, and is provided with a moisture percentage detection operation button near the moisture percentage display device that switches between time display and rice moisture percentage display by button operation. .

There are two ways to adjust the moisture content of rice to the optimum moisture content: automatic control using an electronic circuit that stores the optimum moisture content;
Check the displayed moisture content and manually press the button to humidify or
There is a method of dehumidifying.

Function The measuring rice bin configured as described above not only detects and measures the moisture content of rice during storage and displays the moisture content, but also controls the humidity of rice by humidifying or dehumidifying it. This process provides rice with a uniform moisture content.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In Fig. 1, 1 is a box-shaped water container for storing and preserving rice, and the upper opening of this water container 1 has a lid 2 that can be opened and closed.
covered by. Further, the bottom surface 3 of the water container 1 is formed into a dome shape, and a rice measuring device 4 is provided at the lowest end thereof. 6 is a discharge port for weighed rice. 6 is a leg that supports the water container 1. Reference numeral 7 denotes a humidifier, and this humidifier 7 includes a water container 7a attached to the bottom of the outer bottom of the water container 1. Water is supplied into the water container 7a from a water supply port 8, and the water container 7a It is heated by a heater 9 provided on the outer surface of the humidifier to generate humidifying water vapor. This humidified steam is guided by a steam conduit 1o attached to the side surface of the water container 1 to a humidified steam outlet 11 provided in the water container 1 above the maximum rice storage position. Reference numeral 12 denotes a heating section for dehumidification attached to the outside of the outer bottom surface of the ice container 1.

Reference numeral 13 denotes a sensor that is attached to protrude into the water container 1 and measures the moisture content of the rice.This sensor 13 detects the temperature and humidity of the rice and calculates the moisture content. The measured moisture content of the rice is displayed on a moisture content display device 14 provided on the outer surface of the ice container 1. This moisture percentage display device 1
4, there is an operation opening/closing operation section 1 for opening and closing the operation of a humidifier 7, a heating section 12 for dehumidification, a sensor 13 for measuring the moisture content of rice, an automatic humidity control device, and a moisture percentage display device 14.
There are 6.

The method of measuring the moisture content of rice is to apply a minute voltage between a pair of electrodes facing each other at a distance greater than the width of a grain of rice in a water container 1, and to detect the amount of current flowing between the electrodes and the temperature of the rice. By doing this, the moisture content can be measured. Also,
An automatic humidity control device that determines whether to humidify or dehumidify by comparing the moisture content of rice measured by an electronic circuit that stores the optimum moisture content and supplies power to each heater and heating section. Having one is very convenient and easy to use. In addition, since the moisture content display device does not need to display the moisture content all the time, a moisture content display device that always displays the time is installed, and near the moisture content display device, the time and moisture content can be displayed by pressing a button. If you provide a switching means to switch between rice, when you want to know the moisture content when using or replenishing rice, you can display the moisture content by switching the switching means. will be further improved.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
Since a sensor is installed that protrudes into the visitor container to measure the moisture content of rice, it is possible to accurately measure the moisture content of rice, and the moisture content can be easily determined using the moisture content display device. can.

In addition, if there is a difference compared to the optimum moisture content of rice, it is better to operate the humidifier and dehumidifying heating unit manually or automatically, and to change the moisture content of rice to ensure that the rice always has the optimum moisture content. It is possible to control the humidity.

In this way, by always supplying rice with a constant optimum moisture content during use, there is little variation in rice cooking, and delicious cooked rice can be obtained throughout the year without changing the amount of water depending on the quality of the rice.
