Description

Technical Field

[0001] This utility model relates to the field of fermentation chamber technology, specifically a fermentation chamber for making koji (a type of starter culture) that can naturally release the heat generated during fermentation. Background Technology

[0002] Making koji is a crucial step in the production of fermented foods such as wine and soy sauce. During fermentation, microbial metabolism generates a large amount of heat. If the heat accumulates and cannot be released in time, it will lead to uneven temperature distribution in the storage chamber, affecting the quality of the koji blocks.

[0003] According to application number CN202311001824.6, a circulating fermentation chamber for making soy sauce-flavored baijiu is disclosed in the field of baijiu fermentation technology.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7A fermentation chamber for koji making that allows for natural release of heat generated during fermentation includes a chamber body 1. The top of the chamber body 1 is covered with several small blue tiles, with gaps between them. The front and rear sides of the inner wall of the chamber body 1 are connected by several cylindrical beams, increasing the strength of the chamber body 1. Ventilation holes 100 are provided on the left and right sides of the bottom front of the chamber body 1. The heat generated during fermentation, due to its low density, rises along the chamber body 1 and is released through the gaps in the small blue tiles, while cold air from the outside, due to its higher density, is supplied through the ventilation holes 100. A detachable reinforcing plate 102 is installed on the inner wall of the chamber body 1. The surface of the reinforcing plate 102 is in close contact with the inner wall of the chamber body 1, ensuring airtightness. Reinforcing blocks 6 are fixedly connected to the left and right sides of the bottom of the reinforcing plate 102. The reinforcing blocks 6 have mounting holes, allowing for easy installation of the reinforcing plate 102 using bolts and mounting holes. The structural strength of the silo 1 can be increased by reinforcing plate 102 on the inner wall of the silo 1. The front of the silo 1 is connected to the silo door by hinge. The fermentation process is a publicly available technology, so it will not be described in detail here. The front and back sides of the inner wall of the silo 1 are fixedly connected by several interlocking partitions 103. The partitions 103 facilitate the exhaust of hot air and prevent cold air from entering. A wooden board sloping roof is suspended under the small blue tile roof of the silo 1. A 6cm high space is left for the exhaust vent according to the ratio of the heat steam of each board to the projected area of ​​the ground. The boards are staggered by 20cm width. The advantage is that it can not only allow the hot air in the silo to be discharged smoothly, but also prevent the cold air outside from flowing into the silo in the opposite direction by wind. This ensures the stability of the fermentation temperature in the fermentation silo, achieves efficient fermentation and reasonable humidity control, and realizes a fermentation silo that can naturally exhaust the heat generated during fermentation.

[0027] The hot air generated during fermentation rises along the chamber 1 and is discharged through the gaps in the small blue tiles. Cold air from the outside is supplied through the bottom vent 100. No mechanical devices such as blowers or exhaust fans are needed throughout the process, saving electricity and reducing production energy consumption. The filter screen 23 in the filter connection component 2 can effectively intercept the dust, microbial spores and volatile organic compounds carried in the hot air, preventing them from spreading to the workshop environment or other batches of koji blocks, reducing the risk of cross-contamination. By setting the limiting and fixing component 3, it is convenient to remove the filter screen 23 for cleaning and replacement later, improving the flexibility of use.

[0028] When in use, open the chamber door, evenly pile the fermented koji blocks into the chamber 1, close the chamber door, and after fermentation begins, the heat generated by the microbial metabolism rises along the inside of the chamber 1 because its density is lower than that of cold air. After being filtered by the filter screen 23, it is discharged through the air guide channel 24. After passing through the interlaced partitions 103, it is finally discharged naturally from the gaps in the small blue tiles at the top. At the same time, cold air from the outside enters the chamber 1 from the bottom vent 100, forming a continuous natural convection.
