  • Patent number: 12152820
    Abstract: A refrigeration device, a refrigerator, and a control method therefor, a food processing method and a control device. The refrigeration device includes a compressor, a condenser, a throttling device and an evaporator, and the compressor, the condenser, the throttling device and the evaporator are sequentially connected to form a refrigerant circulation loop; a connecting pipeline between an exhaust port of the compressor and a refrigerant inlet of the throttling device in the refrigerant circulation loop is a first connecting pipeline; and the condenser is arranged on the first connecting pipeline. The refrigeration device further includes an auxiliary heat exchange branch, and the auxiliary heat exchange branch includes a condensing heater for heating a heating region, and is arranged on the first connecting pipeline in parallel; and a first valve device is further arranged on the auxiliary heat exchange branch.

  • Publication number: 20240292850
    Abstract: The present application relates to the field of food processing technology, and provides a method and a device for purine reduction, and an equipment and an electronic equipment and a storage medium. The method for purine reduction includes the following steps: first cooling step: performing first cooling treatment on a food material to be treated at a first preset cooling rate to reduce a temperature of the food material to be treated to a temperature below a freezing point. By performing first cooling treatment on a food material to be treated at a first preset cooling rate to reduce a temperature of the food material to be treated to a temperature below a freezing point, the activity of ATP-degrading enzyme in the food material to be treated can be rapidly inhibited, which can quickly and effectively inhibit the generation of hypoxanthine, thereby reducing the generation of hypoxanthine, reducing the risk of hyperuricemia and gout, and having little effect on the taste and quality of the food material.

  • Patent number: 8890425
    Abstract: The present disclosure relates to blend dimming circuits and methods for driving light loads. In one embodiment, a method can include: converting an external sinusoidal AC power supply to a phase-missing DC voltage signal; detecting a conduction angle of the phase-missing DC voltage signal to generate a first control signal representing the conduction angle; generating an analog dimming signal based on the first control signal; generating, by a PWM dimming circuit, a PWM dimming signal based on the analog dimming signal and a light load feedback signal; regulating light load brightness by PWM dimming when the conduction angle is greater than a threshold angle; regulating the light load brightness by PWM and analog dimming when the conduction angle is less than the threshold angle; and enabling a power stage circuit when the first control signal is active to regulate the brightness of the light load.
