Further, described collet adopt material mainly glass fibre, asbestos, rock wool, silicate, aerogel blanket, evacuated panel one or more.
Further, described door-plate is vacuum interlayer door-plate.
Further, the spray bore of described liquid nitrogen spraying device and water spray system reaches micron order, and liquid spray is formed vaporific.
Further, dismountable pallet is placed with in the mode of draw-in groove bottom described freezing chamber.
A kind of seafood fast freezing case provided by the invention, its control circui mainly liquid nitrogen spraying device is connected with liquid nitrogen spraying device switch, magnetic valve and motor, controlled the operation of the liquid nitrogen spraying device in freezing chamber by liquid nitrogen spraying device switch, thus control the low temperature in freezing chamber; Rotor is connected with motor, rotary switch and magnetic valve, by the operation of switch control rule rotor, controls the rotation of the product on hook and hook further; Water spray system is connected with water spray system switch, magnetic valve and motor, is controlled the operation of the water spray system in freezing chamber by water spray system switch, thus controls the ice layer thickness of seafood further.
After adopting said structure, beneficial effect of the present invention is:
1. green safety.The present invention does not need to add any additive or medicament in implementation process, only need spray liquid nitrogen and water.Liquid nitrogen is all converted into nitrogen in course of defrosting, is directly discharged in air, can't produce any pollution.
2. fast effectively, save the energy.The present invention, in implementation process, is that low-temperature receiver can reduce rapidly seafood surface temperature with liquid nitrogen, simultaneously spray water, and is rapidly converted into ice at low temperatures, and seafood is directly freezing.Whole process is quite quick, shortens the freezing time of seafood, instead of air-conditioning freezing, save the energy.
3. ensure product quality.In spray process, the bore of spray equipment is quite tiny, reaches micron order, formed vaporific in freezing chamber, when water smoke is converted into ice crystal, Particle Phase is when little, is unlikely to stab cell and causes mechanical damage, maintain the original nutritive value of seafood and its color, smell and taste.
