[0037] In one embodiment, the fermentation pot 2 is provided with a steaming partition 22, or the fermentation pot 2 is similar to a steamer structure, and is formed by stacking multiple layers of steamer baskets, so that either the steaming partition 22 or the steamer basket can be placed with garlic, providing garlic Enough fermentation space.
[0038] The working principle of the black garlic fermentation machine disclosed in the present invention is as follows: ①Put fresh garlic heads on the cover 6 or/and steaming compartment 22 in the fermentation pot 2, cover the cover 5 to seal the fermentation pot 2, and then start to open it When the power is switched on, the first heating element 3 and the second heating element 59 will generate heat to heat the fermentation pot 2 while the second heating element 59 heats the fermentation pot 2 from top to bottom through the heat conducting plate 52, and the temperature in the fermentation chamber of the fermentation pot 2 It is raised so that part of the water in the garlic can evaporate to form steam, and because the heating device is located away from the bottom of the fermentation pot 2, the bottom of the fermentation pot 2 forms a condensation part, so most of the steam in the fermentation cavity will be condensed into the condensation part. After the water droplets are left in the water collection cavity, a small part of the steam will be discharged through the steam outlet 532 on the cover 5. Therefore, during the water evaporation stage of the garlic fermentation, most of the water evaporated from the garlic is condensed Afterwards, it remains in the water collection cavity; ②When the garlic can no longer evaporate water at the heating temperature required for fermentation, the fermentation cavity of the fermentation pot 2 still needs to be maintained in a long-term constant temperature and humidity fermentation environment. During this period, the constant fermentation temperature in the fermentation chamber allows the water in the water collection chamber to evaporate slowly, which can ensure that a relatively stable humidity is maintained in the fermentation chamber to ensure the consistency of the fermentation environment. It is black garlic without artificial water addition. The successful fermentation provides a guarantee to improve the reliability of black garlic fermentation.
[0039] In summary, compared with the prior art, the present invention has the following beneficial technical effects:
[0040] 1. By selecting the heating position of the heating device on the fermentation pot, the present invention makes the bottom of the fermentation pot relative to the middle and upper part of the fermentation pot become the condensation part, so that the steam in the fermentation pot encounters the fermentation pot during the heating and evaporation process of the garlic. At the bottom of the pot, it condenses into water droplets and then remains in the water collection cavity. The condensed water collected in the water collection cavity will continue to evaporate slowly at the fermentation temperature to provide the fermentation cavity with relatively stable humidity to ensure the consistency of the fermentation environment and thus become black The successful fermentation of garlic provides a guarantee, so the present invention does not need to add water for humidification in the fermentation process of black garlic, and the success rate of black garlic fermentation is higher.
[0041] 2. Since most of the steam produced in the process of heating and evaporating the garlic is condensed water and only a small part of the steam is discharged through the steam outlet on the cover, the steam discharged during the fermentation of black garlic is less, and the black garlic is fermented The smell of garlic in the environment around the machine is not obvious, which reduces the adverse effects of garlic smell produced during the fermentation process on sensitive personnel.
[0042] 3. The present invention improves the structure of the cover body and makes the following improvements: First, the steam inlet and the steam outlet are arranged in a staggered manner to prevent the condensed water generated by the steam outlet from dripping vertically to the steam inlet and pass through the inner cover. The heat-conducting plate and the second heating element allow the condensed water returned from the steam outlet to fall on the heat-conducting plate to be evaporated again; the second is to set the outer cover with an inclined steam outlet area and the steam outlet at the steam outlet area. Let the condensed water at the steam outlet flow along the inclined surface of the steam outlet area and try not to fall back into the cover; third, the steam inlet is provided with a convex flange to prevent the condensate from entering the steam inlet; There is a steam guide tube between the inner cover and the outer cover to guide the steam in the fermentation pot from the steam inlet to the steam outlet smoothly, to prevent the steam from spreading between the inner cover and the outer cover, and avoid the condensation of steam in the cover. Water is accumulated, so the present invention can prevent the condensed water from flowing back into the fermentation pot by improving the cover structure, avoid the condensed water from affecting the fermentation of black garlic in the fermentation pot, and provide conditions for ensuring the fermentation quality of black garlic.
