Abstract

PURPOSE:To obtain bread having good quality because of not directly applying cool air to bread dough by making it possible to form air passage passing through from one end to other end in the interior of each shelf plate for bread dough and pass air through whole the housing box. CONSTITUTION:Bread dough 6 is put and housed on each shelf plate 5 in a housing box 1. When main changeover switch is changed to low-temperature fermentation or high-temperature fermentation, electricity is applied to air blow unit A and air cooling type freezing unit C. A fan motor in the box it started by applying electricity to air blow unit to rotate the fan in the box and simultaneously U-shaped heater is heated. On the other hand, a compressor is started by applying electricity to the freezing unit and cooling medium is circulated to circulating passage. Air is blown through the U-shaped heater and evaporator to an air blow passage 12 by fan in the box and warm air and cool air is fed in the air blow passage thereby.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a baking machine with a dough fermentation control mechanism for providing high-quality bread, and more specifically, a ventilation device for adjusting the temperature inside the oven. It is related to.

[Prior Art] Methods for producing bread dough include a direct filling method, a medium dough method, and a liquid dough method.

For example, the medium dough method includes dough kneading in which flour, water, yeast, etc. are kneaded, first fermentation, dough kneading in which flour, water, salt, sugar, fats and oils are kneaded, dividing, rounding, intermediate proofing, shaping, etc. It consists of various steps such as die cutting and final foiling.

In this way, the production of bread dough requires many processes and time, so if you want to supply freshly baked bread to consumers, you will have to work around the dough fermentation time, so for example, breakfast Supplying freshly baked bread to workers requires grueling late-night and early-morning labor.

To address this issue, baking machines have been developed that can freely control the fermentation of bread dough.

This foam allows the fermentation to be controlled freely by adjusting the fermentation time, temperature, humidity, etc., thereby improving the working hours of manufacturers and freeing them from harsh late-night and early-morning labor. It is.

[Problems to be Solved by the Invention] However, in conventional baking machines, a device is installed to adjust the temperature and humidity inside the oven to control the fermentation of bread dough. Since the adjustment mechanism is configured to simply blow cold air into the oven using an air-cooled refrigeration unit and a cold air circulation path, the cold air directly hits the dough inside the oven.

As a result, there was a problem that the bread dough was damaged and the quality was impaired.

The present invention was made in view of the above-mentioned problems of the conventional bread proofing machine, and its purpose is to properly control the temperature inside the oven without damaging the bread dough, and to maintain the temperature even after fermentation has stopped. The purpose is to provide a baking sheet that can maintain a proper fermentation state for a long time without impairing the quality of bread dough, and can make high-quality bread.

[Means for Solving the Problems] In order to achieve the above object, the baking sheet of the present invention has a breadboard from one end to the other inside each shelf board for placing a plurality of bread doughs arranged in multiple stages in a refrigerator. A ventilation passage penetrating to the end is formed, and one end of each ventilation passage is communicated with a ventilation passage defined on one side of the interior of the refrigerator and connected to the ventilation unit, so that the entire interior of the refrigerator can be ventilated through each ventilation passage. It is characterized by having the other end opened into the refrigerator.

[Effect] Bread dough is placed and stored on each shelf board in the storage.

When the main switch is switched to low-temperature fermentation (retard) or high-temperature fermentation, the blower unit and air-cooled refrigeration unit are energized.

The internal fan motor is started by energizing the ventilation unit, the internal fan is rotated, and the U-shaped heater is heated.

On the other hand, when electricity is applied to the refrigeration unit, the compressor is started, and the refrigerant circulates through the circulation passage.

The circulation passage is recessed in the outer periphery of the evaporator installed in the unit hook of the air blowing unit, so that the internal fan blows air into the ventilation passage inside the storage via the U-shaped heater and the evaporator. As a result, hot air and cold air are blown into the air passage.

The refrigeration unit operates constantly to lower the temperature inside the refrigerator. Further, if the temperature inside the refrigerator becomes higher than the set temperature, the power supply to the U-shaped heater is cut off by operating the overtemperature rise prevention switch.

Therefore, by operating the overtemperature rise prevention switch as necessary, the temperature of the air blown into the air passage can be adjusted to an appropriate temperature.

When the air is blown into the ventilation passage in the refrigerator, it is passed through the ventilation passage inside each shelf board whose one end communicates with the passage, and then through each ventilation passage and the entire interior of the refrigerator from the opening at the other end. become.

Further, the humidifying water from the evaporator is sent into the refrigerator as high-humidity cold air by an internal fan.
