Yoghourt fermenting apparatus, refrigerator and yoghourt fermenting method

Abstract

A provided yoghourt fermenting apparatus comprises a housing, a fermentation chamber enclosed by the housing, and a heating device; the fermentation chamber is inside provided with a temperature sensor and a yoghourt cup for holding a substance; the bottom of the yoghourt cup is provided with a mass sensor measuring the mass of the substance in the yoghourt cup; and the fermenting apparatus also comprises a controller for adjusting the heating device and enabling the device to reach a preset fermentation temperature at preset time and keep the fermentation temperature. The yoghourt fermenting method employing the yoghourt fermenting apparatus comprises utilizing the temperature sensor and the mass sensor to measure the temperature and the mass of fresh milk, and controlling the heating device via a temperature signal and a mass signal through the controller, so as to enable fresh milk with any mass and temperature to be able to reach a preset fermentation temperature at preset time. By using the method, the heating process before fermentation is controllable, the temperature of fresh milk is capable of rapidly rising to the fermentation temperature, growth of harmful bacteria during heating is limited, and therefore the yoghourt quality can be improved.

Description

technical field [0001] The invention relates to a yogurt fermentation device, in particular to a yogurt fermentation device with controllable heating process before yogurt fermentation, a refrigerator with the yogurt fermentation device and a yogurt fermentation method using the yogurt fermentation device. Background technique [0002] Yogurt is a milk product made from fresh milk, which is pasteurized or other sterilized, and then beneficial bacteria (starter) are added to the milk, fermented, and then cooled. Yogurt not only retains all the advantages of milk, but also develops its strengths and circumvents its weaknesses in some aspects through processing, becoming a nutritional and health product more suitable for human beings. In order to prolong the shelf life or adjust the taste, all yogurt products currently on the market have additives. [0003] In order to ensure food safety, modern families usually use small-scale yogurt machines to make fresh yogurt by themselve...

AI Technical Summary

Problems solved by technology

The heating power of the heating device in this yogurt machine is fixed and cannot be adjusted. Since the quality and temperature of the fresh milk used for fermentation by the user vary each time, the heating process before fermentation is uncontrollable; especially when the fresh milk put in When there is more milk and the temperature is lower, the temperature rises to the fermentation temperature slowly and takes a long time, which makes the growth of harmful microorganisms faster in the process and affects the quality of yogurt

In addition, after the fermentation of yogurt is completed, the yogurt needs to be moved from the yogurt machine to the refrigerator or freezer for refrigeration. However, due to the high temperature of the freshly fermented yogurt, it is not convenient to move, so it is easy to cause excessive fermentation of the yogurt
