Abstract

The utility model relates to the field of household appliances and in particular relates to a yogurt maker. The yogurt maker with the fermentation degree reminding function comprises an outer shell, an inner shell, a vessel, an inner cover and an outer cover, wherein the inner shell is arranged in the outer shell; a cavity is reserved between the outer shell and the inner shell; the vessel is arranged in the inner shell and is matched with the inner cover; the outer cover is matched with the outer shell; a heating end of a PTC (positive temperature coefficient) heating mechanism comes into contact with the bottom surface of the vessel via a heat transfer plate after passing through the inner shell; a PH value detection sensor is installed in the vessel; a detection head of the PH value detection sensor is arranged in the middle position of the vessel; a PLC (programmable logic controller) is used for controlling and connecting the PTC heating mechanism and the PH value detection sensor. The yogurt maker has the beneficial effects that the PH value detection sensor is installed in the vessel and is utilized to detect signals to determine the fermentation degree of yogurt, and when fermentation of the yogurt is confirmed to have been completed, the PLC controls the PTC heating mechanism to stop working, thus ensuring the quality of the yogurt.

Description

There is the Yogurt making machine that attenuation degree is reminded

Technical field

The utility model relates to household appliance technical field, relates in particular to a kind of Yogurt making machine.

Background technology

Yoghourt can promote the secretion of digestive juice, increases hydrochloric acid in gastric juice, thereby can strengthen people's digestion power, promotes appetite; Lactic acid in Yoghourt not only can make the alkalescent material in enteron aisle be transformed into faintly acid, and can also produce antibacterial material, with health role to human body; Some lactic acid bacteria energy synthetic vitamin C, increase Vit C contents; Yoghurt can also suppress the growth of enteron aisle spoilage organisms, also contain the active material that can suppress synthetic cholesterol reductase in body, can stimulate body immune system again, transfer the active factor of body, effectively resist cancer, so frequent food acids milk can have additional nutrients, prevent and treat artery sclerosis, coronary heart disease and cancer, reduce cholesterol.

Modern Family, in order to guarantee food security, avoids additive that many small-sized Yogurt making machine self-control fresh yoghurts that all can use are arranged.Sour milk-making device is a device that steady temperature is provided to milk fermentation, and the fermentation temperature of lactic acid bacteria is best 42 ℃ of temperature, under this environment, and the probio amount reproduction, lactose changes into lactic acid, and milk fermentation becomes Yoghourt.

Yogurt making machine on market is that full automatic energising is directly heated mostly now, adopt the heating component of appropriate power to control temperature, use PTC to be heated, the temperature difference of PTC pyrotoxin is very large, design temperature common temperature difference in the time of 42 ℃ is ± 8 ℃, because temperature difference fluctuation is large, caused the fermentation time of Yoghourt to be difficult to grasp; The common time, while being set as doing the fermentation source with pure Yoghourt, fermentation time was 6～8 hours; While with ferment agent for sour milk, doing the fermentation source, fermentation time 8～12 hours, while using the pure milk fermentation in refrigerator, no longer than 14 hours, the fermentation time of this rough setting was difficult to guarantee the Yoghourt quality.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of Yogurt making machine that attenuation degree is reminded that has, by the pH value detecting sensor has been installed in container, confirm the state of Yoghourt fermentation, after Yoghourt fermentation completes, PLC controller control PTC heating arrangements quits work, and has guaranteed the quality of Yoghourt.

The utility model is achieved in that a kind of Yogurt making machine that attenuation degree is reminded that has, comprise shell body, inner housing, container, inner cap and enclosing cover, described inner housing is arranged in shell body, leave cavity between shell body and inner housing, described container is placed in inner housing, described inner cap matches with container, and described enclosing cover matches with shell body; PTC heating arrangements and PLC controller are housed in described cavity, the heating end of described PTC heating arrangements contacts with the bottom surface of container by heat transfer plate after through inner housing, the pH value detecting sensor is housed in described container, the detecting head of described pH value detecting sensor is arranged on the centre position of container, PLC controller control connection PTC heating arrangements and pH value detecting sensor.

Described pH value detecting sensor is the glass electrode sensor.

Described shell body also is equipped with temperature adjustment knob outward.

Described temperature adjustment knob has two gears.

Between described shell body and inner housing, hold together.

Described heat transfer plate is aluminium sheet, copper coin, corrosion resistant plate, aluminium alloy plate.

Go back Central Symmetry on described inner housing and be provided with a pair of tank of getting.

The Yogurt making machine that the utlity model has the attenuation degree prompting has been installed the pH value detecting sensor in container, utilize pH value detecting sensor detection signal to determine the attenuation degree of Yoghourt, when confirming that Yoghourt has fermented, the PLC controller is controlled the PTC heating arrangements and is quit work, and has guaranteed the quality of Yoghourt.
