The invention belongs to the field of processing low-temperature cooked meat products, and relates to an improved vacuum precooling treatment method for low-temperature cooked meat products. Before the vacuum precooling of low-temperature cooked meat products, the refrigeration unit (4), the low-temperature liquid circulation pump (5) and the electric valve (13, 14) are turned on, and the auxiliary device group (7) and the condenser are connected through the heat exchanger (21). The temperature of (18) drops to the set temperature; put the cooked low-temperature cooked meat products into the auxiliary device group (7) at the same time, turn on the vacuum pump (2) and control the pressure drop rate, according to the position of the low-temperature cooked meat products In different temperature sections, adjust the opening of the electric valves (13, 14) to control the flow of the corresponding branch pipelines I and II, so that the temperature control of the auxiliary device group (7) and the condenser (18) can be realized. The invention can not only obtain high cooling rate and low water loss for low-temperature cooked meat products, but also maintain high color and luster quality of low-temperature cooked meat products, and has simple operation and low energy consumption.

The invention discloses a high-sensitivity C-arm CT device, which belongs to the field of photoelectric imaging. A high-sensitivity C-arm CT device includes a CT detector assembly. The CT detector assembly includes a detector protective shell, which is flexible and telescopic. The outer end of the shielding ring is connected with a number of matching load-bearing buffer components. Through the cooperation of the load-bearing buffer component, flexible telescopic shielding ring and isolated push component, it can effectively block the interference of the X-ray receiving plate and assist The cooler promotes the heat dissipation of the X-ray receiving board, effectively reducing the degree of temperature interference to the X-ray receiving board, thereby improving the stability of the signal conversion of the X-ray receiving board, improving the sensitivity of the CT detector components, and effectively improving the C-arm CT equipment. The image quality of the main body can effectively reduce the energy of X-rays, reduce the damage caused by the C-arm CT equipment main body to the patient's body, and improve the safety of the C-arm CT equipment main body.

The invention belongs to the fresh-keeping method of red bayberry, relates to a method for accelerating the precooling rate in the vacuum precooling process of red bayberry. ), and then transferred to the vacuum pre-cooler for pre-cooling, turn on the refrigeration system of the vacuum pre-cooler, then turn on the vacuum pump and control the pressure drop rate, so that the bayberry is rapidly cooled in a vacuum environment, and the metal ice can be processed after pre-cooling. Recycling, and then quick freezing can be used next time, so as to achieve recycling. The invention can not only make the red bayberry obtain a rapid cooling rate, but also reduce the water loss during the vacuum pre-cooling process, and also increase the shelf life of the red bayberry. Finally, the metal ice after the pre-cooling can be recycled. , which can effectively reduce operating costs.

The invention belongs to the field of processing equipment for low-temperature cooked meat products, and relates to a device for assisting vacuum precooling of low-temperature cooked meat products. The device is composed of a hollow body base plate (21), an accommodating cavity (20) and a refrigerant (22). The upper plane of the hollow body base plate (21) is connected to form a sealed hollow area with other parts of the hollow body base plate (21) except for the accommodating cavity (20), and the brine (22) is filled in the hollow area to form the device. The device is built into the vacuum box (1) of the vacuum pre-cooling system after low-temperature treatment, and cooperates with the vacuum pre-cooling system to complete the pre-cooling of steamed low-temperature cooked meat products. After reorganization, the unit device can be applied to vacuum precooling of large-scale low-temperature cooked meat products, thereby realizing industrial production.

The invention discloses a heat dissipation system of an underground box type transformer, comprising a natural convection heat dissipation system mechanism formed by air chutes arranged around a transformer body in a pit box and a ventilation opening arranged on the ground. The heat dissipation system is characterized by further comprising a reinforced heat exchange mechanism which is arranged onat least one outer wall of the transformer body (4) and contacted with the inner wall of the pit box (1), so that the heat generated by the transformer body (4) is transmitted into the pit box (1) through the reinforced heat exchange mechanism, and the heat is then transferred into the surrounding stratum through the pit box. The heat dissipation system combines natural ventilation and forced ventilation, and adopts surface soil layer heat dissipation, so as to improve the heat dissipation effect and ensure lasting and stable heat dissipation; furthermore, the size of the pit box can be reduced to the utmost extent, and the pre-buried underground space is saved.
