Description

Technical Field

[0001] This utility model relates to the field of food fermentation technology, and in particular to a food fermentation device with a temperature control module. Background Technology

[0002] Fermentation is an indispensable part of the production process of many foods. It not only affects the taste, aroma and quality of food, but also relates to the nutritional components and safety of food. Fermentation equipment and production methods used in food production usually involve the control and optimization of the fermentation process to ensure the good growth of microorganisms and product quality during the production process. It is quite common in food fermentation processing.

[0003] However, existing food fermentation equipment requires weighing each part of the ingredients first, then calculating the weight of the seasonings based on the weight of the ingredients, and then placing them all into the fermentation tank. The whole process is quite cumbersome and time-consuming. At the same time, temperature has a crucial impact on the fermentation process, so the fermentation equipment needs real-time temperature feedback and precise temperature control. Furthermore, vacuum storage of the fermented food is also very important. Utility Model Content

[0004] The purpose of this invention is to solve or alleviate the shortcomings of the existing technology and to provide a food fermentation device that enables real-time temperature feedback and precise temperature control during the fermentation process, thereby ensuring fermentation efficiency and effectiveness.

[0005] The purpose of this utility model is achieved as follows: A food fermentation device with a temperature control module includes a main housing and a fermentation container. The fermentation container includes a fermentation tank body and a fermentation tank lid that covers the upper opening of the fermentation tank body. The main housing has a fermentation container placement cavity, and the fermentation tank body is placed on the fermentation container placement cavity. The device is characterized by further including a temperature control module, which includes a heating element and a cooling element. The heating element is fixed to the outer wall of the fermentation container placement cavity, and the cooling element is fixed to the outer bottom wall of the fermentation container placement cavity. The main housing has a display control module, and the fermentation tank lid has a temperature measuring element, one end of which extends into the fermentation tank body. The display control module is electrically connected to the heating element, the cooling element, and the temperature measuring element.

[0006] This food fermentation device with a temperature control module works in concert with the display control module, temperature control module, and temperature measuring device. The temperature measuring device transmits the detected temperature inside the fermentation tank to the display control module in real time. At the same time, the display control device directly controls the operation of the heating and cooling components, so that the temperature of the fermentation container cavity accurately reaches and maintains the set temperature. In other words, it realizes real-time temperature feedback and precise temperature control during the fermentation process, ensuring fermentation efficiency and effect.

[0007] The objective of this utility model can also be achieved by the following technical measures: Specifically, it further includes a metal inner liner, with a support base connected inside the main housing. The support base has a support cavity, and the metal inner liner is placed on the support cavity. A through-hole is opened on the main housing corresponding to the inner cavity of the metal inner liner. The inner cavity of the metal inner liner constitutes the fermentation container placement cavity. The fermentation tank passes through the through-hole from top to bottom and is placed on the inner cavity of the metal inner liner. The heating element is attached to the outer wall of the metal inner liner, and the cooling element is attached to the outer bottom wall of the metal inner liner. The metal inner liner has a fast temperature transfer speed, which allows the temperature on the heating and cooling elements to be quickly transferred to the fermentation container placement cavity and the fermentation tank. Furthermore, the support base can support the metal inner liner well, which is beneficial to the stable placement of the metal inner liner in the main housing, thereby allowing the fermentation tank to be stably supported on the fermentation container placement cavity.

[0008] Specifically, it also includes a sealing ring, which is clamped between the upper surface of the metal inner liner and the inner top wall of the main body housing, with one end of the sealing ring abutting against the outer wall of the fermentation tank. On the one hand, the sealing ring can play a good guiding role in the placement of the fermentation tank on the fermentation container placement cavity. On the other hand, the sealing ring can effectively seal the gap between the fermentation tank and the fermentation container placement cavity, preventing heat from leaking out from the gap and achieving a good heat preservation effect. At the same time, it can also prevent external debris from falling into the gap.

[0009] Specifically, the heating element is a silicone heating sheet, which is attached to the outer wall of the metal inner liner; silicone heating sheets are readily available and have good implementation effects.

[0010] Furthermore, a foaming agent is placed between the outer periphery of the metal inner liner and the inner wall of the support cavity, and the foaming agent wraps around the outer periphery of the silicone heating element; the foaming agent can play a good role in heat preservation and protection of the silicone heating element, ensuring the heating effect and stability of the silicone heating element.

[0011] Specifically, it further includes a heat sink and a cooling fan. The cooling component is a PTC cooling chip. One end of the PTC cooling chip is attached to the outer bottom wall of the metal inner liner, and the other end of the PTC cooling chip abuts against the upper surface of the heat sink. The lower surface of the heat sink abuts against the cooling fan. This allows the heat sink and the cooling fan to dissipate the heat generated by the PTC cooling chip in a timely manner, ensuring the stable operation of the PTC cooling chip.

[0012] Specifically, the bottom of the support base has a clearance through hole, the PTC cooling chip is located inside the clearance through hole, and the bottom of the support base located outside the clearance through hole is also connected to a support frame. The support frame has a mounting platform, and the bottom of the mounting platform has a through hole. The cooling fan and the heat sink are sequentially mounted on the mounting platform. Through the cooperation of the support base and the support frame connected to its bottom, the cooling fan, the heat sink and the PTC cooling chip can be mutually resisted and cooperated. At the same time, the hot air discharged by the cooling fan can be discharged in time from the through hole at the bottom of the mounting platform.

[0013] Specifically, it further includes a ventilation duct, one end of which is connected to the lower part of the support frame. The bottom of the through hole extends outward into a limiting groove. One end of the ventilation duct is inserted into the limiting groove. An air outlet is opened on the inner wall of the main unit housing. The other end of the ventilation duct extends to a position close to the air outlet. This allows the hot air discharged by the cooling fan to flow through the ventilation duct to the air outlet and finally be discharged outside the main unit housing, preventing the hot air from affecting the stable operation of other components inside the main unit housing.

[0014] Specifically, the main unit housing includes a base, a hollow shell, and a top cover. The base is connected to the lower opening of the hollow shell, and the top cover is connected to the upper opening of the hollow shell. The base has an air outlet, and a limiting wall extends upward from the base outside the air outlet. The other end of the ventilation pipe extends into the limiting wall. The side wall of the hollow shell has an air inlet. The air inlet facilitates the entry of external air into the main unit housing, which absorbs the heat from the PTC cooling chip and becomes hot air, which is then discharged through the cooling fan. Furthermore, the limiting wall cooperates with the other end of the ventilation pipe so that the hot air discharged through the ventilation pipe can be discharged outside the main unit housing through the air outlet.

[0015] The beneficial effects of this utility model are as follows: (1) This food fermentation device with temperature control module displays the coordinated operation of the control module, temperature control module and temperature measuring element. The temperature measuring element transmits the detected temperature inside the fermentation tank to the display control module in real time. At the same time, the display control device directly controls the operation of the heating element and the cooling element, so that the temperature of the fermentation container cavity accurately reaches the set temperature and is maintained. That is, it realizes real-time temperature feedback and precise temperature control during the fermentation process, ensuring fermentation efficiency and effect.

[0016] (2) On the one hand, the sealing ring can play a good guiding role in the placement of the fermentation tank on the fermentation container placement cavity. On the other hand, the sealing ring can effectively seal the gap between the fermentation tank and the fermentation container placement cavity, preventing heat from leaking out from the gap and achieving a good heat preservation effect. At the same time, it can also prevent external debris from falling into the gap.

[0017] (3) The hot air discharged by the cooling fan flows through the ventilation pipe to the air outlet and is finally discharged outside the main unit casing to avoid the hot air affecting the stable operation of other components inside the main unit casing. Attached Figure Description
