Description

Technical Field

[0001] This invention relates to the field of pasta processing equipment, and in particular to a proofing and heating steaming device. Background Technology

[0002] The traditional segmented processing mode used in the current pasta processing field is prone to causing flavor loss and abnormal texture in the finished pasta products. In view of this, the applicant filed a patent application in 2025 with application number 202510460538.9 for a refrigerator, proofing and heating integrated machine. The equipment is equipped with an integrated chassis, and the interior of the chassis is divided into an independent processing chamber and an equipment chamber by a partition. The equipment chamber is equipped with a refrigeration device, a heating device and a steam generator respectively. The partition is equipped with an openable and closable ventilation window to connect the two chambers. The equipment can switch between three working modes: refrigeration, proofing and heating. It relies on a fan to transport the gas with the adjusted temperature and humidity to the interior of the processing chamber to complete the pasta processing operation.

[0003] However, the prior patent relies solely on natural diffusion within the chamber to transport gas, which cannot construct a complete closed-loop airflow circulation path. After the gas completes the heat and moisture exchange with the food, there is no dedicated channel for it to return to the fan, and the airflow cannot be continuously recycled. During the operation of the equipment, heat and moisture will continuously evaporate and be lost, making it difficult to maintain a uniform and stable temperature and humidity in the environment where multiple layers of food are stacked. Summary of the Invention

[0004] In view of the shortcomings mentioned above, the present invention provides a proofing and heating device.

[0005] The present invention adopts the following technical solution: A proofing and heating device includes: A unit housing, wherein a fan and a heating and humidifying assembly are built into the unit housing, and the air outlet of the fan is connected to the heating and humidifying assembly; A drawer stand, wherein a cavity is formed inside the drawer stand, and an air vent is formed at the upper end of the drawer stand, and multiple steamers are vertically stacked above the air vent on the drawer stand; An annular body is disposed between two adjacent steamers stacked on the upper end of the drawer base; The output end of the heating and humidifying component is connected to the cavity of the drawer seat, and the annular body is connected to the air inlet of the fan through a pipe.

[0006] In one possible implementation, the heating and humidifying assembly includes a heating module and a humidifying module arranged sequentially along the airflow direction; the heating module is used to heat the airflow, and the humidifying module is used to replenish water vapor to the heated airflow.

[0007] In one possible implementation, the heating module includes a first housing and a first heating element, the first heating element being disposed inside the first housing, one end of the first housing being connected to the air outlet of the fan, and the other end of the first housing being connected to the humidification module.

[0008] In one possible implementation, the humidification module includes a second housing and a second heating element. A water storage cavity is formed inside the second housing, and the second heating element is arranged in the water storage cavity. The air inlet of the second housing is connected to the heating module, and the air outlet of the second housing is connected to the interior space of the drawer seat.

[0009] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: The present invention sets up a unit box, a drawer seat and an annular body to cooperate with each other to form a closed airflow circulation path connected to the ventilation fan, so that after the airflow completes the heat and moisture exchange with the food inside the multi-layer steamer, it can flow back to the fan through the annular body and pipes, thereby realizing the circulation and reuse of airflow, alleviating the situation of continuous heat and moisture loss due to evaporation. At the same time, the circulating hot and humid airflow can be evenly applied to all the stacked steamers, ensuring that the temperature and humidity of the processing environment of the multi-layer food is kept uniform and stable, and simultaneously carrying out proofing or steaming heating, greatly reducing the loss of heat and moisture, and simultaneously improving the processing efficiency of batch food and the energy utilization effect of the equipment.

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in further detail below with reference to the accompanying drawings.

[0016] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0017] Furthermore, in this embodiment, directional terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used to describe and clarify relative positions, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0018] This invention provides a proofing and heating integrated proofing and steaming device, as shown in the attached figure. Figure 1 and 2 As shown, the steaming equipment includes a unit housing 1, a drawer base 2, and an annular body 3. The unit housing 1 houses a fan 4 and a heating and humidifying assembly 5, with the fan 4's outlet connected to the heating and humidifying assembly 5. The drawer base 2 has an internal cavity, and the output end of the heating and humidifying assembly 5 is connected to the cavity of the drawer base 2 via a first pipe 71. An air duct 201 is formed at the upper end of the drawer base 2, and multiple steaming baskets 6 are vertically stacked above the air duct 201. The placement surface of the steaming baskets 6 has perforated gaps to allow air communication between the stacked steaming baskets 6. The annular body 3 is positioned between adjacent steaming baskets 6 stacked on the upper end of the drawer base 2. (Refer to the attached diagram.) Figure 3 The annular body 3 is connected to the air inlet of the fan 4 via a second pipe 72. Preferably, the second pipe 72 can be a high-temperature resistant flexible hose. In the above structure, the hot and humid airflow is delivered from the heating and humidifying component 5 to the cavity of the tray 2 and then passes upward through the multi-layer steamer 6, continuously exchanging heat and moisture with the food inside the steamer 6. The airflow that has completed the heat and moisture exchange is collected by the annular body 3 and flows back to the air inlet of the fan 4 along the pipe, thus forming a complete closed airflow circulation loop. This effectively balances the temperature and humidity distribution inside each layer of the steamer 6, reduces the loss of heat and moisture, improves energy utilization, and enables continuous proofing and heating processing of the food.

[0019] As attached Figure 4 and 5As shown, the heating and humidifying assembly 5 includes a heating module 51 and a humidifying module 52 arranged sequentially along the airflow direction. The heating module 51 heats the airflow, and the humidifying module 52 replenishes the heated airflow with water vapor. Specifically, the heating module 51 includes a first housing 511 and a first heating element 512. The first heating element 512 is arranged inside the first housing 511, and one end of the first housing 511 is connected to the air outlet of the fan 4. The humidifying module 52 includes a second housing 521 and a second heating element 522. A water storage chamber is formed inside the second housing 521, and the second heating element 522 is disposed in the water storage chamber. The air inlet end of the second housing 521 is connected to the first housing 511 of the heating module 51, and the air outlet side of the second housing 521 is connected to the interior space of the drawer seat 2. Preferably, both the first heating element 512 and the second heating element 522 can be electric heating tubes, which convert electrical energy into heat energy to heat the airflow and water. The heated airflow enters the second housing 521. The water in the water storage chamber is heated by the second heating element 522, causing the water to heat up and generate water vapor. The water vapor mixes thoroughly with the airflow, and the mixed hot and humid airflow is transported to the drawer 2, continuously supplying the steamer 6 to complete the proofing and heating process, as detailed below: When the equipment is in the proofing mode, the fan 4 continuously drives the airflow circulation. The first heating element 512 heats the airflow to the proofing temperature, and the second heating element 522 maintains low power operation. The water in the water storage chamber generates an appropriate amount of water vapor. The airflow and water vapor mix to form low-temperature and high-humidity air. The hot and humid airflow is delivered to the tray 2 and passes through the multi-layer steamer 6 to proof the food in the steamer 6. The airflow that has completed the heat and moisture exchange flows back to the fan 4 through the annular body 3 and the pipes to enter the next cycle.

[0020] When the equipment is in heating mode, the fan 4 maintains airflow circulation, the first heating element 512 increases the output airflow temperature, the second heating element 522 increases the output power, the water in the water storage chamber generates a large amount of water vapor, the airflow and water vapor are fully mixed to form a high temperature and humid airflow, the high temperature and humid airflow is delivered to the tray 2 and passes through the multi-layer steamer 6 to steam and heat the food in the steamer 6, and the airflow that has completed the heat and moisture exchange returns to the fan 4 through the annular body 3 and the pipe fittings to continue the circulation operation.

[0021] In summary, the steaming and humidifying equipment constructed in this invention, through a closed airflow circulation loop and a segmented heating and humidifying component 5, can achieve two processing modes: food proofing and heating / steaming. During processing, the uniformly circulating hot and humid airflow can simultaneously cover multiple stacked steamers 6, allowing the food inside the steamers 6 to undergo proofing or heating simultaneously. The equipment can complete batch processing of food in a single operation, effectively increasing processing capacity and shortening the total batch processing time. Furthermore, the closed airflow circulation loop reduces heat and moisture loss. The heating module 51 and humidifying module 52 independently regulate the airflow temperature and water vapor generation, stably adapting to the environmental requirements of different processing conditions. While ensuring the uniformity and quality of food processing at each layer, it significantly improves overall processing efficiency and energy utilization.

[0022] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using the concept of the present invention shall constitute an infringement of the protection scope of the present invention.
