Description

Domestic machine for making sour milk

Technical field

It is little electric to the present invention relates to family expenses, relates in particular to the domestic machine for making sour milk that can change the heat environment.

Background technology

Along with growth in the living standard, people more and more pay attention to diet health, contain abundant biodiasmin in the sour milk, and people's health is had many benefits, as improve a poor appetite, reduce cholesterol, anti-ly treat constipation, aid digestion and anti-disease etc., be subjected to everybody liking deeply.The sour milk major part of being sold on the market at present is that suitability for industrialized production is come out, owing to links such as the storage that needs process, transportation, sale, add compositions such as some stabilizing agents or anticorrisive agent in the sour milk inevitably, and these compositions do harm rather than good health, and have also lost original freshness through the long-time sour milk that stores.

It (is ' abbreviation of Positive Temperature Coefficient ' that existing Yogurt making machine adopts PTC, positive heat coefficient semiconductor thermal sensitive ceramics stratie) or the heating wire heating its Chinese:, the environment of a basic constant temperature is provided to the lactic acid bacteria in the container of domestic machine for making sour milk, lactic acid bacteria is breeding in a large number under this environment, makes the sour milk that is fit to individual taste to certain hour.Make make sour milk after, if untimely change heat environment or its taking-up deposited in addition, the time is long more, lactic acid bacteria is just many more, sour milk is just sour more, even rotten so that can not drink.

Summary of the invention

The object of the invention provides a kind of domestic machine for making sour milk that cools to refrigeration below 6 ℃ after sour milk is made automatically.

Above purpose is achieved through the following technical solutions: Yogurt making machine is provided with top cover, shell and inner casing, the bottom of shell is connected with heat dissipating housing, heat dissipating housing is provided with air inlet and air outlet, in heat dissipating housing, be provided with fan near the air inlet place, be arranged with heat transfer device outside the inner casing, form fermentation chamber, be provided with insulation material between heat transfer device and the shell, wherein the bottom of shell is provided with semiconductor cooler, its one side connects with heat transfer device, within the another side of semiconductor cooler, heat dissipating housing, be provided with radiator, on the wall of inner casing or heat transfer device, be provided with the heat inductor.

The container that the milk that contains lactic acid bacteria to be fermented is housed is set in the fermentation chamber.

The present invention adopts above technical scheme, utilizes the characteristics that semiconductor cooler one side is cold, another side is warm, when fermentation time is finished, changes the polarity of voltage of semiconductor cooler, makes original heating surface become huyashi-chuuka (cold chinese-style noodles) below 6 ℃, and another side then becomes hot side; Fan is from air inlet inspiration wind radiator, make the cold and hot surface of semiconductor cooler that the higher temperature difference be arranged, guarantee that the semiconductor cooler service behaviour is better, so sour milk can transfer refrigeration to automatically after fermentation is finished, the sour milk of guaranteeing the domestic machine for making sour milk fermentation has fresh-keeping function, and more convenient people use.

Description of drawings

Now in conjunction with the accompanying drawings the present invention is further elaborated:

Fig. 1 is the internal structure schematic diagram of one of Yogurt making machine of the present invention;

Fig. 2 is two an internal structure schematic diagram of Yogurt making machine of the present invention;

Fig. 3 is three an internal structure schematic diagram of Yogurt making machine of the present invention;

The specific embodiment

As Fig. 1, shown in 2 or 3, Yogurt making machine of the present invention is provided with top cover 1, shell 3 and inner casing 2, the bottom of shell 3 is connected with heat dissipating housing 6, heat dissipating housing 6 is provided with air inlet 61 and air outlet 62, in heat dissipating housing 6, be provided with fan 7 near air inlet 61 places, be arranged with heat transfer device 4 outside the inner casing 2, form fermentation chamber 5, the milk that contains lactic acid bacteria to be fermented is housed in the fermentation chamber 5 container 8 that the milk that contains lactic acid bacteria to be fermented is housed maybe can be set, the quantity of container 8 is according to the size of itself and fermentation chamber 5, place one or more,, the fixed support 81 of container 8 can be set for convenient fixing.Inner casing 2 can be made different shapes with heat transfer device 4: as shown in Figure 1, heat transfer device 4 is made cup-shaped, directly is set in inner casing 2 outsides; As shown in Figure 2, inner casing 2 bottom hollow outs, heat transfer device 4 is embedded in the hollow out place, form send out the chamber pure at the bottom of; As shown in Figure 3, heat transfer device 4 is also made cup-shaped, and inner casing 2 is made the ring flange shape.Be provided with insulation material 13 between heat transfer device 4 and the shell 3, make the heat in the fermentation chamber 5 keep stable, wherein the bottom of shell 3 is provided with semiconductor cooler 9, semiconductor cooler 9 can be according to the size of fermentation chamber 5, with container 8 corresponding employings one or more, form a plurality of fermentation chamber 5, its one side 91 connects with heat transfer device 4, two working faces 91 at semiconductor cooler 9, be coated with one deck heat conductive silica gel on 92, more help the heat transmission, another side 92 at semiconductor cooler 9, be provided with radiator 10 within the heat dissipating housing 6, heat transfer device 4 and radiator 10 adopt metal material or other Heat Conduction Material usually, be provided with heat inductor 11 on the wall of inner casing 2 or heat transfer device 4, heat inductor 11 can adopt thermistor.

When the container 8 that the milk that contains lactic acid bacteria to be fermented is housed places in the fermentation chamber 5, the setting fermentation time starts, the one side 91 of semiconductor cooler 9 begins heating, this moment, another side 92 was a huyashi-chuuka (cold chinese-style noodles), by thermal conductive surface 4 heat is delivered to fermentation chamber 5, common lactic acid bacteria is fermented best about 37 ℃, is lower than 6 ℃ of azymic, and surpassing 70 ℃ of lactic acid bacterias can mortality.When inner casing 2 or heat transfer device 4 heats surpass when setting heat, heat inductor 11 is given the microprocessor of Yogurt making machine with signal feedback, and whether the work of control semiconductor bulk refrigerator 9, can guarantee that so the heats in the fermentation chamber 5 keep constant.When fermentation time is finished, microprocessor changes the polarity of voltage of semiconductor cooler 9, and semiconductor cooler 9 original heating surfaces 91 become the huyashi-chuuka (cold chinese-style noodles) below 6 ℃, and 92 of another sides become hot side, so just realize the present invention after sour milk is made, cool to the purpose of refrigeration below 6 ℃ automatically.
