Description

The Yogurt making machine of automatic cold storage

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, and design temperature common temperature difference in the time of 42 ℃ is ± 8 ℃, and the temperature of lactic acid bacteria survival should not be too high, due to excessive temperature differentials, many times temperature approaches 50 ℃, causes a large amount of lactic acid bacterias to be killed, and the nutritive value of Yoghourt is had a greatly reduced quality; Because temperature difference fluctuation is large, caused the fermentation time of Yoghourt to be difficult to grasp in addition.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of Yogurt making machine of automatic cold storage, change on the Yogurt making machine inner housing semiconductor chilling plate additionally has been installed, after selecting fermentation time by control panel, by PLC controller timing controlled semiconductor chilling plate, opened, even when making Yoghourt, nobody looks after like this, Yoghourt can not addle because of undue fermentation yet, has facilitated family's use.

The utility model is achieved in that a kind of Yogurt making machine of automatic cold storage, 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 inner ring middle part of described container is provided with a circle semiconductor chilling plate, the middle part laminating of semiconductor chilling plate and container, PLC controller control connection PTC heating arrangements and semiconductor chilling plate.

Described shell body is equipped with control panel outward, and described control panel is provided with temperature adjustment knob and time control handle.

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 of the utility model automatic cold storage has additionally been installed semiconductor chilling plate on inner housing, after selecting fermentation time by control panel, by PLC controller timing controlled semiconductor chilling plate, opened, even when making Yoghourt, nobody looks after like this, Yoghourt can not addle because of undue fermentation yet, has facilitated family's use.

Fig. 2 is decomposing schematic representation of the present utility model;

The schematic cross-section that Fig. 3 is the utility model housing part.

In figure: 1 shell body, 2 inner housings, 3 containers, 4 inner caps, 5 enclosing covers, 6 cavitys, 7PTC heating arrangements, 8 heat transfer plates, 9 semiconductor chilling plates, 10 control panels, 11 are got tank, 12PLC controller.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are not used in restriction scope of the present utility model for the utility model is described.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.

Embodiment 1

As shown in Figure 1, 2, 3, a kind of Yogurt making machine of automatic cold storage, comprise shell body 1, inner housing 2, container 3, inner cap 4 and enclosing cover 5, described inner housing 2 is arranged in shell body 1, leave cavity 6 between shell body 1 and inner housing 2, described container 3 is placed in inner housing 2, and described inner cap 4 matches with container 3, and described enclosing cover 5 matches with shell body 1; PTC heating arrangements 7 and PLC controller 12 are housed in described cavity 6, the heating end of described PTC heating arrangements 7 contacts with the bottom surface of container 3 by heat transfer plate 8 through inner housing 2 is rear, the inner ring middle part of described container 3 is provided with a circle semiconductor chilling plate 9, semiconductor chilling plate 9 is fitted with the middle part of container 3, PLC controller 12 control connection PTC heating arrangements 7 and semiconductor chilling plates 9.

In the utility model, described shell body 1 is outer is equipped with control panel 10, and described control panel 10 is provided with temperature adjustment knob and time control handle.

In the utility model, in order to enlarge the scope of application of this Yogurt making machine, can also manufacture other beverages as the rice wine class except preparing Yoghourt, the outer temperature adjustment knob 10 that also is equipped with of described shell body 1; In the present embodiment, described temperature adjustment knob has two gears, and one grade is arranged on 42 ℃, and one grade is arranged on 30 ℃, and this sample Yogurt making machine both can be used for preparing Yoghourt, can prepare rice wine again.
