As shown in attached drawing 3 and attached drawing 4, supporting rack 8 is respectively arranged on the left side and the right side in fast freezing case 4, the side wall of fast freezing case 4 with
Supporting rack 8 is connected and fixed.
As shown in attached drawing 3 and attached drawing 4, in the cabinet of the fast refrigerating cabinet, it is provided with the channel system of control liquid nitrogen trend.It is logical
Road system include be arranged at the top of every layer of fast freezing case and the inlet channel 9 of bottom, fast freezing case on the left of diffusor duct 10, fast freezing case
Pumping air channel 12 on the right side of the balance air duct 11 on right side, balance air duct and liquid nitrogen feed path 13, each air duct and channel it is specific
Setting is as follows：
As shown in attached drawing 3 and attached drawing 4, inlet channel 9 is made of the gap between each layer fast freezing case, the bottom plate of fast freezing case with
The top plate of lower layer's fast freezing case forms inlet channel, and 9 both ends open of inlet channel, wherein setting is independent at the top of the fast freezing case of top
Channel top plate 14, the both sides of channel top plate 14 fix with supporting rack 8, shape between channel top plate 14 and the top plate of top layer fast freezing case
At the inlet channel of top.Individual channel base plate 15, channel base plate 15 and both sides are arranged in the fast freezing case bottom of the bottom
Supporting rack 8 is connected and fixed, and wherein 15 left end of channel base plate is bent downward is connected and fixed with the bottom plate of cabinet 1, channel base plate 15
Right end extends out to outside supporting rack 8.
As shown in Fig. 3, diffusor duct 10 is made of the space between 4 left side of fast freezing case and cabinet left plate.
As shown in Fig. 3, it balances air duct 11 and the space on 4 right side of fast freezing case, balance is arranged in cabinet in pumping air channel 12
Separated by vertical partition plate 16 between air duct 11 and pumping air channel 12, vertical partition plate 16 and the outside extended right end of channel base plate 15
Portion is connected and fixed, and the top of vertical partition plate 16, which extends upwardly to 14 top of channel top plate and bends to the left, to be extended channel top plate
The space of top is divided into two channels up and down, and upper channel is liquid nitrogen feed path 13, lower channel 17 and diffusor duct 10, balance
Air duct 11 and each inlet channel 9 penetrate through, and liquid nitrogen diffusing opening 18 is equipped between lower channel left end and cabinet left plate.
As shown in Fig. 3, lower channel 17, diffusor duct 10, inlet channel 9, balance air duct 11 composition one are relatively independent close

The effect that case uniformly freezes.If the liquid nitrogen of the presence without balance air duct 11, atomization is entered by 9 left side of inlet channel, the right is taken out
Go out, liquid nitrogen can be entered inside air admission hole 5 in the form of inclined, and close to the inlet channel left side air admission hole will without liquid nitrogen into
Enter, cause in fast freezing case 4 the right and left temperature that cannot synchronize decline, frozen finish in the right occurs and the also non-deep colling in the left side lacks
It falls into, and if extending cooling time, the frozen material on the right in fast freezing case can be caused to burst, cause quick-frozen failure.
The fast refrigerating cabinet further respectively has Pan Kou plugs into disk mouth 7 and placing mouth, in use, opening into the Pan Kou on disk mouth 7
Plug puts quick-frozen object in refrigerator tray, and by being pushed into disk mouth 7, refrigerator tray advances multiple refrigerator trays along track 6, when being occupied in cabinet
When refrigerator tray, is blocked into disk mouth 7 with Pan Kou plugs, set the quick-frozen time, after reaching the quick-frozen time, remove into disk mouth 7 and placing
Pan Kou plugs on mouth, another batch of refrigerator tray into disk mouth 7 by being pushed into, and the quick-frozen refrigerator tray finished is released by placing mouth, when new
After refrigerator tray fills cabinet, filled in into Pan Kou and placing mouth with Pan Kou block carry out it is quick-frozen.
Using the feeding manner, due to being blocked into Pan Kou and placing mouth by refrigerator tray while feeding discharging, when quick-frozen
It is filled in and is blocked by Pan Kou, therefore can effectively reduce the spill-out of liquid nitrogen, relative to opening door liquid nitrogen flash freezer cabinet, liquid nitrogen loss can drop
Low 20% or more.
The work of liquid nitrogen spraying head 3 in order to control is internally provided with temperature sensor 19 in diffusor duct 10 as shown in Fig. 3.
