Abstract

The utility model relates to the field of household appliances and in particular relates to a yogurt maker. The automatic temperature control yogurt maker 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 PTC (positive temperature coefficient) heating mechanism and a PLC (programmable logic controller) are installed in the cavity; a heating end of the PTC heating mechanism comes into contact with the bottom surface of the vessel via a heat transfer plate after passing through the inner shell; a temperature sensor is installed in the vessel; a detection head of the temperature sensor is arranged in the middle position of the vessel; the PLC is used for controlling and connecting the PTC heating mechanism and the temperature sensor. The yogurt maker has the beneficial effects that the temperature sensor is utilized to measure the temperature of the central point of the vessel and then transmit the measured temperature to the PLC, and when the temperature exceeds the set threshold, the PLC controls the PTC heating mechanism, thus reducing temperature fluctuation in the vessel when yogurt is prepared and improving the quality of the yogurt.

Description

Temperature automatically controlled Yogurt making machine

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 temperature automatically controlled Yogurt making machine, by temperature sensor and PLC controller have been installed in container, utilize the feedback signal of temperature sensor, realize the control of PLC controller control to the work of PTC heating arrangements, dwindle the temperature fluctuation in container while preparing Yoghourt, improved the quality of Yoghourt.

The utility model is achieved in that a kind of temperature automatically controlled Yogurt making machine, 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, in described container, temperature sensor is housed, the detecting head of described temperature sensor is arranged on the centre position of container, PLC controller control connection PTC heating arrangements and temperature 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 temperature automatically controlled Yogurt making machine of the utility model has been installed temperature sensor and PLC controller in container, send the PLC controller to after utilizing temperature sensor to record container center point temperature, when temperature surpasses setting threshold, the PLC controller is controlled the PTC heating arrangements and is quit work or reopen, dwindle the temperature fluctuation in container while preparing Yoghourt, improved the quality of Yoghourt.
