Description

Technical Field

[0001] This utility model belongs to the field of rice and flour product fermentation technology, specifically a fermentation device for quick-freezing fermented rice and flour production and processing. Background Technology

[0002] Frozen rice and noodle products require a fermentation process during production. Fermented rice and noodle products have a soft texture and a unique fermented aroma. During fermentation, the rice and noodle products are placed in a fermentation chamber for constant temperature and humidity treatment to improve the quality of the fermentation.

[0003] In related technologies, fermentation devices typically incorporate heating and humidification equipment at the bottom of the fermentation chamber. The heat and moisture generated by these devices are used to maintain a constant temperature and humidity inside the fermentation chamber. However, in practical use, it has been found that the heat rises, and during the heating process, there is a temperature difference (approximately 2°C to 5°C) between the upper and lower layers of the fermentation chamber. This uneven temperature distribution can affect the consistency of fermentation of rice and flour products in the upper and lower layers of the chamber, indicating room for improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a fermentation device for quick-freezing fermented rice and flour production and processing in order to solve the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A fermentation device for quick-freezing fermented rice and flour production and processing includes a fermentation box. The inner walls of both ends of the fermentation box are vertically provided with partitions, which separate a fermentation chamber and two circulation channels. The top of the partition is provided with a through hole that communicates with the fermentation chamber and the circulation channels. A water tank is installed at the bottom of the fermentation chamber. The water tank has a water-containing cavity with an open top, and an electric heating element for heating the water is provided at the bottom of the water-containing cavity. Air blowers are provided at both ends of the water tank. The air blowing direction of the two air blowers is upward, and the air suction direction of the two air blowers is respectively connected to the bottom of the two circulation channels.

[0006] In a preferred embodiment, the water tank is generally I-shaped, and the two ends of the water tank are recessed in opposite directions to form grooves for accommodating the two blower components.

[0007] In a preferred embodiment, the blower is a turbine fan, and the air inlet of the turbine fan is equipped with an air duct that communicates with the circulation channel.

[0008] In a preferred embodiment, the water tank is also equipped with a temperature sensor and a water level sensor.

[0009] In a preferred embodiment, the opposite end faces of the two partitions protrude from top to bottom to form multiple sets of supporting convex surfaces, and a feeding rack is detachably installed on the supporting convex surfaces, and multiple ventilation holes are distributed at intervals on the feeding rack.

[0010] In a preferred embodiment, an ozone generator is installed on the top of the fermentation tank, and the ozone emission end of the ozone generator is connected to the fermentation chamber.

[0011] In a preferred embodiment, the fermentation chamber is further equipped with a temperature and humidity sensor and an ozone concentration sensor.

[0012] In a preferred embodiment, the front end of the fermentation tank is also hinged to a door, and the door is provided with a transparent viewing panel.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: A circulating channel is designed connecting the upper and lower layers of the fermentation chamber, and a blower is designed at the bottom of the circulating channel to connect with it. During the operation of the fermentation chamber, the blower can be used to draw the hot air from the upper layer of the fermentation chamber back into the lower layer through the circulating channel, and then repeat the circulation. This solves the problem of uneven temperature distribution, thereby ensuring the consistency of rice and flour product fermentation in the upper and lower layers of the fermentation chamber, and is worthy of promotion.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] Reference Figure 1-3A fermentation device for quick-frozen fermented rice and flour production includes a fermentation box 5. Partitions 7 are vertically arranged on the inner walls of both ends of the fermentation box 5, forming a fermentation chamber 6 and two circulation channels 3. A through hole 2 is provided at the top of the partition 7, communicating with the fermentation chamber 6 and the circulation channels 3. A water tank 9 is installed at the bottom of the fermentation chamber 6. The water tank 9 has a water-containing cavity with an open top, and an electric heating element 10 for heating the water is provided at the bottom of the water-containing cavity. Air blowers 8 are provided at both ends of the water tank 9, and the air blowers 8 are positioned in different directions. The two blowers 8 are positioned facing upwards, and their suction directions are connected to the bottom of the two circulation channels 3 respectively. The upper and lower layers of the fermentation chamber 6 are connected by circulation channels 3, and the bottom of the circulation channels 3 is connected to the blowers 8. During the operation of the fermentation device, the blowers 8 can be used to draw the hot air from the upper layer of the fermentation chamber 6 back into the lower layer of the fermentation chamber 6 through the circulation channels 3, and then repeat the circulation. This can solve the problem of uneven temperature between the upper and lower layers, thereby ensuring the consistency of fermentation of rice and flour products in the upper and lower layers of the fermentation chamber 6.

[0020] The electric heating element 10 is preferably a PTC ceramic heating element, but this is not a limitation.

[0021] It should be noted that a waste discharge pipe for collecting condensate is also designed at the bottom of fermentation tank 5, and a valve is designed on the waste discharge pipe.

[0022] Furthermore, the water tank 9 has an overall I-shaped structure, with the two ends of the water tank 9 recessed in opposite directions to form grooves 13 for accommodating the two blowers 8. This design ensures that the blowers 8 can blow the hot and humid air generated by heating the water tank 9 upwards during the hot air circulation process, thus enabling the rapid diffusion of hot and humid air inside the fermentation chamber 6.

[0023] Furthermore, the blower 8 is a turbine fan, and the air inlet of the turbine fan is equipped with an air duct 12 that is connected to the circulation channel 3. An electric heating mesh (not shown in the figure) is also added to the air outlet of the turbine fan to achieve auxiliary heating. The turbine fan has a stronger air force than the traditional fan, which makes the subsequent exhaust air force stronger and can achieve the effect of rapid circulation.

[0024] Furthermore, a temperature sensor 14 and a water level sensor 15 are also installed inside the water tank 9. The temperature sensor 14 and the water level sensor 15 can monitor the temperature and water level changes inside the water tank 9 in real time to avoid overheating. The temperature sensor 14 and the water level sensor 15 are technologies known in the prior art, and their specific models and structures will not be described here.

[0025] Furthermore, the opposite end faces of the two partitions 7 protrude from top to bottom to form multiple sets of supporting convex surfaces. A feeding rack 4 is detachably installed on the supporting convex surfaces. Multiple ventilation holes 41 are distributed at intervals on the feeding rack 4. The size of the ventilation holes 41 only needs to be designed to be smaller than the size of the rice and flour products, but it is sufficient to allow gas to pass through. The specific size is not limited here. The ventilation holes 41 on the feeding rack 4 can ensure that the gas can flow up and down along the ventilation holes 41.

[0026] Furthermore, an ozone generator 1 is installed on the top of the fermentation tank 5. The ozone discharge end of the ozone generator 1 is connected to the fermentation chamber 6. After a period of use, all the internal items can be removed, and the ozone generated by the ozone generator 1 is discharged into the fermentation chamber 6, where it is then circulated by the blower 8, thus disinfecting the interior of the fermentation chamber 6. The ozone generator 15 is a known technology in the prior art; its specific model and structure will not be described here.

[0027] Furthermore, the fermentation chamber 6 is also equipped with a temperature and humidity sensor 16 and an ozone concentration sensor. These sensors can collect real-time data on temperature and humidity changes and ozone concentration values ​​within the fermentation chamber 6. The front of the fermentation tank 5 is also hinged to a door 11, which has a transparent viewing panel. The fermentation chamber 6 also features a control panel (not shown in the figure) for controlling the aforementioned electronic components (such as the temperature and humidity sensor, ozone concentration sensor, temperature sensor 14, water level sensor 15, and blower 8).

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
