This utility model relates to the field of cooling equipment technology, and in particular to an open-type circulating cooling device, including a bottom pool frame. An operation key is fixedly connected to the center of the front end of the bottom pool frame, and a drain pipe is fixedly connected to the left front end of the bottom pool frame. A cooling tower shell is fixedly connected to the upper left and upper right inner walls of the bottom pool frame. A viewing window is provided at the upper front end of the cooling tower shell, and a cooling structure is fixedly connected to the center of the inner wall of the cooling tower shell. An axial flow fan is provided at the center of the upper end of the cooling tower shell, and six baffles are fixedly connected in a circular array on the upper inner wall of the axial flow fan. This open-type circulating cooling device utilizes a water-saving water spray device to reduce water waste, and combines a cooling structure and an axial flow fan to improve cooling efficiency. The viewing window facilitates observation, the drain pipe is easy to clean, and the baffles prevent water splashing, achieving high efficiency, water conservation, stable operation, and convenient maintenance.

The invention belongs to the technical field of artificial boards, and relates to a manufacturing process of a high-water-content low-imbibition floor base material, which comprises the steps of glue mixing and applying, pre-pressing, hot pressing and the like. When glue is mixed and applied, waterproof low-melamine-proportion modified urea-formaldehyde resin (55-57% of formaldehyde, 31-35% of urea and 8-14% of melamine), a curing agent and a composite formaldehyde reducing agent are applied according to a specific formula. The resin is synthesized by adopting an alkali-acid-alkali-alkali four-stage process. In the pre-pressing step, microwave heating is adopted to heat the slab core layer to 60-70 DEG C; continuous hot pressing is adopted for hot pressing, and five-section temperature partition and four-section pressure distribution are optimized. Through the synergistic effect of a special resin formula, microwave preheating of a plate blank and optimization of a hot pressing process, on the premise that the use amount of melamine is remarkably reduced, the obtained floor base material obtains the low water absorption thickness swelling rate, meanwhile, the water content is increased to 6.0-7.0%, the size stability is better, the formaldehyde release amount is effectively controlled, and the service life of the floor base material is prolonged. The production efficiency is improved; and the cost is reduced.

A method for cooling of Pseudosciaena crocea after slaughter, which is completed by the way of temporary breeding, fish selection, losing consciousness in saturated CO2 environment of 20 DEG C, bleeding, removing viscera and gill, ion water flushing, fluidized ice cooling, packaging and cold storage. The method of losing consciousness in saturated CO2 environment can effectively reduce the adverse effects of fish muscle activity and ATP degradation in fish meat caused by slaughter stress on the texture, color and shelf life of fish fillets. Fluidized ice cooling immediately after slaughter can keep a lower pH value, inhibit protein degradation, slow down water loss and muscle softening. The present application can be used as a recommended pre-cooling technology to maintain the quality and biochemical properties of proteins during cold storage of Pseudosciaena crocea.
