Abstract
The utility model discloses a temperature control liquid nitrogen quick freezing device which comprises a cabinet body, a liquid nitrogen storage tank, a temperature sensor, a valve and a controller. The inner wall of the cabinet body is covered by heat insulating materials, so that a cold chamber is formed in the cabinet body, and a liquid nitrogen outlet is formed in the cold chamber. The liquid nitrogen storage tank is arranged on the outer side of the cabinet body and connected with the liquid nitrogen outlet. The temperature sensor is arranged in the cold chamber. The valve is arranged on the connection route of the liquid nitrogen storage tank and the liquid nitrogen outlet. The controller is connected with the temperature sensor so as to receive temperature signals of the temperature sensor and connected with the valve so as to control opening and closing of the valve. The lowest temperature of liquid nitrogen of the temperature control liquid nitrogen quick freezing device can reach -196 degrees, the rate of temperature fall can reach -50 DEG C per minute, and the quick freezing time is 3-18 minutes. Moisture of food will not lose, and weight, taste, color, texture and cooking time of the food are not affected. Ice crystal particles are small, and therefore loss of moisture and nutrition in cell tissue is avoided.
