Abstract
Description
Technical Field
[0001] This utility model relates to a constant temperature heating device, and more particularly to a fermentation tank capable of constant temperature heating. Background Technology
[0002] In the pasta processing industry, fermentation is the core step that determines the quality of pasta products. From Chinese steamed buns and dumplings to Western baked goods like bread, the fermentation process, through the metabolic activities of microorganisms, gives dough its unique flavor, texture, and fluffiness. For example, during dough fermentation, yeast breaks down sugars to produce carbon dioxide and alcohol. The carbon dioxide causes the dough to expand, giving the pasta a soft texture. However, yeast fermentation is extremely sensitive to dough temperature. The suitable fermentation temperature is usually between 25℃ and 35℃. Temperatures that are too high or too low will affect yeast activity, leading to under- or over-fermentation of the dough, thus affecting the final quality of the pasta.
[0003] However, traditional fermentation tanks used for dough fermentation suffer from numerous technical bottlenecks. Most traditional fermentation tanks use a single heat source, such as a heating device at the bottom of the tank. This results in uneven temperature distribution within the tank, with the dough at the bottom overheated while the dough at the top under-ferments, leading to inconsistent fermentation and ultimately inconsistent taste and quality of the produced dough products. While some fermentation tanks are equipped with temperature sensors, the location and accuracy of these sensors are problematic, making it impossible to accurately monitor temperature changes in different areas of the tank in real time. This hinders precise temperature control and results in unstable dough fermentation.
[0004] Furthermore, traditional fermentation tanks have shortcomings in component connections and power supply methods. The connection between the heating module and the control module of the fermentation tank is complex, and installation and disassembly are inconvenient, making equipment maintenance and repair difficult; the stability of the electrical connection is poor, and problems such as poor contact are prone to occur, affecting the normal operation of the heating module; and there is a lack of flexibility in heating power adjustment, making it impossible to accurately adjust the heating power according to different stages of dough fermentation, such as slow fermentation in the early stage and rapid fermentation in the middle stage, making it difficult to achieve intelligent and precise control of the dough fermentation process. Utility Model Content
[0005] To address this problem, this utility model proposes a constant temperature fermentation tank comprising a tank body, a base, and a control module. The base includes a heating element. The tank body is a hollow structure with an open bottom and a closed top. The bottom of the tank body is detachably covered on the base. The heating element is equipped with a first heating module, and the top of the tank body is equipped with a second heating module. The first heating module and the second heating module are electrically connected to the control module. The control base is located inside the base, and the control module is electrically connected to an external power source.
[0006] Furthermore, it also includes a connecting part, with an electrical connection module at the bottom of the connecting part. The base further includes electrical contacts, and the electrical connection module and the electrical contacts are connected accordingly. The electrical contacts are electrically connected to the control module, and the second heating module is electrically connected to the control module through the connecting part.
[0007] Furthermore, the electrical connection module includes a first magnetic element, and a second magnetic element is disposed on one side of the electrical contact, with the first magnetic element and the second magnetic element being attracted to each other.
[0008] Furthermore, the electrical contacts are further connected to a transformer unit, and the second heating module is electrically connected to the control module through the transformer unit.
[0009] Furthermore, the first heating module includes a first heater, and the second heating module includes a second heater, wherein the heating power of the second heater is less than that of the first heater.
[0010] Furthermore, both the first heating module and the second heating module are equipped with a temperature-conducting plate and a temperature sensor. The first heater and the second heater are respectively attached to the temperature-conducting plate, and the temperature sensor is electrically connected to the control module.
[0011] Furthermore, a groove is provided on the base along the periphery of the heating part, and the bottom periphery of the tank is inserted into the groove.
[0012] Furthermore, the connecting part is located on the side of the outside of the tank.
[0013] Furthermore, the top of the tank also includes a vent.
[0014] Furthermore, a top cover is provided at the top of the tank, and the second heating module is located inside the top cover.
[0015] Therefore, according to the above technical solution description, the beneficial effects of this utility model are as follows: the first heating module and the second heating module set at the bottom and top of the can body can achieve coordinated heating of the dough inside the can from top to bottom. This dual heating source design effectively avoids the problem of uneven temperature inside the can caused by traditional single bottom heating, ensuring that all parts of the dough are heated evenly and guaranteeing the consistency of dough fermentation. Furthermore, the different heating power settings of the first and second heaters, combined with the control module, can flexibly adjust the heating intensity to precisely meet the temperature requirements of different stages of dough fermentation, effectively improving yeast activity and reducing under- or over-fermentation, thereby significantly improving the taste and quality of noodle products.
[0016] Secondly, the electrical connection module employs a design where the first magnetic element and the second magnetic element on one side of the electrical contact attract each other, enhancing the stability of the electrical connection and effectively avoiding the poor contact problems that are prone to occur in traditional connection methods, ensuring the stable operation of the heating module. Furthermore, the transformer unit connected to the electrical contact works in conjunction with the control module to flexibly adjust the heating power according to fermentation requirements, achieving intelligent and precise control of the dough fermentation process, further improving fermentation efficiency and product quality.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0048] Please refer to Figures 1-6 This utility model mainly proposes a constant temperature fermentation tank, including a tank body 1, a base 2, and a control module (not shown in the figure). The base includes a heating part 21, and the control module is set inside the base 2. The tank body 1 is a hollow structure with an open bottom end 11 and a closed top end 12. The bottom end 12 of the tank body 1 is detachably covered on the base 2. The base 2 is provided with a groove 20 along the periphery of the heating part 21. The periphery of the bottom end 11 of the tank body 1 is inserted into the groove 20. The top end 12 of the tank body 1 also includes a vent hole 13 and a top cover 14.
[0049] The heating section 21 is provided with a first heating module 210, which includes a first heater 211, a temperature guide plate 212, and a temperature sensor 213. The top 12 of the tank body 1 is provided with a second heating module 120. More specifically, the second heating module 120 is located inside the top cover 14 of the top 12 of the tank body 1. The second heating module 120 includes a second heater 121, a temperature guide plate 122, and a temperature sensor 123. The first heating module 210 and the second heating module 120 are electrically connected to the control module. The temperature sensor 213 in the first heating module 210 and the temperature sensor 123 in the second heating module 120 transmit the temperature information on the temperature guide plates 212 and 122 to the control module. In this embodiment, the power of the second heater 121 is less than the power of the first heater 211. The control module is located inside the base 2 and is electrically connected to an external power source.
[0050] The constant temperature fermentation tank of this application also includes a connecting part 3, which is disposed on the side of the tank body 1 and extends from the top 12 of the tank body 1 to the base 2. An electrical connection module 31 is disposed at the bottom of the connecting part 3. The base 2 further includes an electrical contact 22. The electrical connection module 31 and the electrical contact 22 are connected to each other. The electrical contact 22 is electrically connected to the control module. The second heating module 120 is electrically connected to the control module through the connecting part 3. The electrical connection module 31 includes a first magnetic element 32 and a second magnetic element 23 is disposed on one side of the electrical contact 22. The first magnetic element 32 and the second magnetic element 23 are correspondingly attracted to each other. The first magnetic element 32 and the second magnetic element 23 mainly serve as alignment and anti-mistake measures when the electrical connection module 31 is connected to the electrical contact 22. At the same time, the attraction between the first magnetic element 32 and the second magnetic element 23 can prevent the connecting part 3 from easily detaching from the base 2, ensuring the stability of the electrical connection.
[0051] Furthermore, since the heating power of the second heater 121 is less than that of the first heater 211, the electrical contact 22 is further connected to a transformer unit (not shown in the figure), and the second heating module 120 is electrically connected to the control module through the transformer unit.
[0052] In use, the raw materials to be fermented are placed in the container, and then the container is placed on the heating part 21 of the base 2. After the tank body 1 is covered, the settings can be made by using the button connected to the control module. Different heating powers can be set for the first heating module 210 and the second heating module 120 respectively. Alternatively, a temperature inside the tank body 1 can be set, and the control module can calculate the heating power required by the first heater 211 and the second heater 121. Then, the approximate temperature inside the tank body 1 is calculated by using the temperature sensors 213 in the first heating module 210 and 123 in the second heating module 120 respectively. The heating power of the first heating module 210 and the second heating module 120 can also be adjusted according to different fermentation processes to achieve better fermentation results.
