There are various processing steps under the above environment, but
A typical example is a bacterial culture device. In order to control the temperature and humidity of the culture substrate, air that is adjusted based on arbitrary settings is supplied. Humidity is usually carried out in a high humidity state, and there are various types of measuring instruments for controlling this humidity. The higher the humidity, the more difficult it becomes to control the settings, and the errors are not small.

Currently, in various industrial instruments, humidity indicators, controllers, humidity recorders, etc. all detect the difference in dry and wet temperatures, and convert the temperature difference into humidity. Also, the relative humidity ratio due to the difference in dry and wet temperatures is
As seen in the psychrometric diagram, the higher the humidity, the narrower the temperature difference and the greater the change in humidity. An example of the relationship between temperature change and humidity is: 35℃ RH - 100% increases by 0.5℃, RH = 96% 1.0℃ 〃 RH = 92% 1.5℃ 〃 RH = 88% 2.0℃ 〃 RH = 84 The relationship is like %.

である。 One of the causes of humidity errors is the moisture film formed on the surface of the dry bulb sensor protection tube. This is because the dry bulb sensor protection tube itself cannot instantaneously follow temperature changes due to its high specific heat, and temperature fluctuations cause condensation on the surface of the protection tube, forming a film of moisture. This moisture film causes the temperature to approach the wet bulb temperature, causing a large error in the humidity conversion value. Some measures are being taken to prevent condensation by providing air flow around the sensor, but the current situation is that it is not very effective in high humidity environments.

Here, this invention dehumidifies a part of the air in a room equipped with heating bodies on both sides of dry bulb temperature and wet bulb temperature in the humidity measurement of high-humidity air in the fermentation industry, and makes it the same temperature as the indoor temperature. By continuously supplying air over the entire surface of the dry-bulb temperature sensor and measuring the dry-bulb temperature in an atmosphere of dehumidified air, errors in dry-bulb temperature caused by condensation and evaporation can be eliminated, and wet-bulb temperature can be measured. This paper aims to improve the measurement accuracy of temperature and dry bulb temperature, and proposes a method to obtain highly accurate humidity measurements.

湿度測定が得られるものである。 In the above-mentioned culture apparatus, a koji substrate 2' is deposited on a culture bed 2, and a circulation device (not shown) is used to aerate the conditioned indoor air into the koji substrate to perform culture. In the process, various humidity adjustments are required, so a humidity controller 3 is provided. Humidity control is set to this humidity controller 3, and its signals are linked to a temperature and humidity controller (not shown). As shown in FIG. 3, the wet bulb sensor 4 is designed to form a water film on the surface of the temperature sensor, and the dry bulb sensor 5 is designed to form a water film on the surface of the temperature sensor.
As shown in the figure, a conduit 6 and an air supply port 1 are arranged around the outer circumference of the temperature sensor 7 so that the temperature can be measured in the atmosphere of the supply air over the entire sensor area.
2 is provided. Air sucked through the indoor air intake port 11 is dehydrated and dehumidified by a dehydrator 10, and sent to a heat exchanger 8 provided indoors by a blower 9. The heat exchanger 8 heat-exchanges the air that has been dehydrated and dehumidified by the dehydrator 10 so that it reaches the same temperature as the indoor air while passing through the heat exchanger 8, and supplies air as shown in FIG. It is supplied from the port 12 and supplied to the area around the temperature sensor 7 through the conduit 6 at the same temperature as the room temperature, so that condensation on the dry bulb sensor due to temperature fluctuations is completely prevented and accuracy is improved. It is capable of high temperature measurements and provides accurate humidity measurements in relation to wet bulb temperature.
