Description

[Detailed description of the device]

[0001]

[Industrial application] This invention is for freezing bread dough,
The present invention relates to a do conditioner that can perform refrigeration storage and fermentation with one unit. Recently, the de conditioner has been attracting attention as a device for reducing labor shortage, particularly night shift and early shift in the baking industry.

[0002]

2. Description of the Related Art Generally, a do conditioner freezes or stores refrigerated bread dough, etc., and adjusts the temperature and humidity in the refrigerator to a range suitable for fermenting the dough by manual operation or timer operation. It is a device that can ferment sequentially from refrigerated storage.

[0003] A conventional deconditioner generally has a cooler for refrigeration and freezing and a heater device for controlling the fermentation temperature. These two devices are installed in an air-conditioning room that is separated from the inside where the bread dough and the like are placed, and they are switched and operated by a timer operation or a manual operation incorporated in the control device. Adjust the temperature and convert. The air in the cabinet is blown by the fan as shown by the arrow in Fig.8,
The temperature and humidity are circulated through the inside of the refrigerator one after another, and the temperature and humidity are detected by the temperature and humidity sensor installed above. Temperature control is performed by operating a cooler or heater device with a temperature / humidity sensor and a control device.

When the bread dough is fermented (pull fur state), the inside temperature is generally 20 ° C to 40 ° C.
Since it is set to the range of, and a certain amount of humidity is required in the refrigerator,
Humidification is performed with a humidifier. For this humidification, the humidifier is operated by the control device in accordance with the internal humidity information sensed by the temperature and humidity sensor.

[0005]

[Problems to be Solved by the Invention] However, in the conventional deconditioner, the cooler and the heater device are installed together in the air-conditioning room, and the cooler is in contact with the humidified air during the fermentation state (pull fur state). When the dough is cooled (retarder), water will condense when it cools. Generally, the cooler is provided with fins having a large surface area in order to increase the cooling capacity. Therefore, the amount of water dewed on the cooler at the time of retarder becomes a considerable amount, and when the temperature rises at the time of pulling, it evaporates and excessively humidifies the inside of the refrigerator. With a small Du Conditioner, the amount of water that has condensed on the cooler immediately causes the inside of the refrigerator to become saturated with water vapor. In particular, in the case of a store conditioner, the volume inside the store is extremely small due to the store area, and this tendency is remarkable.

When the puller state is set in such a water vapor saturated state, the humidity control becomes impossible, and there is a problem that excessive humidity causes adverse effects such as stickiness of the surface of the cloth. This is a problem that further causes the quality of the final product to be significantly deteriorated.

An object of the present invention is to provide a small-sized conditioner which is often used for stores, and which prevents excessive humidification due to water condensed on the cooler without attaching a special dehumidifying device.

[0008]

[Means for Solving the Problems] In order to achieve this purpose,
This invention provides a deconditioner with two passages, an air heating passage provided with a heater device for raising the air temperature in the refrigerator and an air cooling passage provided with a cooler for lowering the air temperature in the refrigerator, and An opening / closing means for opening / closing the two passages is provided.

Further, the du conditioner is provided with two passages, that is, an air heating passage provided with a heater device for raising the air temperature in the refrigerator and an air cooling passage provided with a cooler for lowering the air temperature in the refrigerator, and An opening / closing means for opening / closing the two passages is provided, and one passage is formed separately from the main body of the conditioner.

[0010]

When the du conditioner is used in the retarder state, the opening / closing means is operated so that the air flows only through the air cooling passage provided with the cooler. When the du conditioner is used in the puller state, the opening / closing means is operated so that the air flows only through the air heating passage provided with the heater device.

When it is desired to dehumidify in the puller state, the cooler is operated to sufficiently cool the cooler while the air is being circulated in the air heating passage provided with the heater device. Then, the opening / closing means is positioned so that the air flows through both of the two passages. Humidity of the air is lowered because the vapor in the refrigerator adheres to the cooler where the air has cooled to cause dew condensation. When the humidity is appropriately lowered, the cooler is stopped, the opening / closing means is activated again, and the air is circulated only through the air heating passage provided with the heater device.
