Specific embodiment
As shown in Fig. 1-3, low temperature blood plasma quick freezer, including cabinet, cabinet is interior to be arranged partition 2, and 2 side of partition is freezing
Room 20, freezing chamber 20 is interior to be arranged pallet 9, and circulating fan 5 is arranged in 2 other side of partition, and circulated air 5 machine band movable vane piece rotation is blown.
Evaporator 3 is set below blade, air outlet 8 and return air inlet 1 are set on partition 2, air outlet 8 is located at 1 top of return air inlet.Freezing chamber
The shaft 10 of rotation is arranged in rotation in 20, and pallet 9 is arranged in shaft 10, and pallet 9 is rotated with shaft 10.Blood is placed on pallet 9
Starch bag.Pallet 9 has multilayer.Because pallet 9 rotates, it is traditionally arranged to be circle, blood plasma supporting plate 16 is set thereon, for placing
Plasma bags.Bearing 11 is set between shaft 10 and instant freezer shell.In cold wind temperature-fall period, shaft 10 drives plasma bags to turn
It is dynamic, it eliminates part plasma bags caused by the dead angle position or cold air deficiency position of wind circulation and cools down irregular equal phenomenon, pole
The uniformity and quality of the plasma freezing of big raising.Multiple air holes are set on pallet 9, guarantee that wind circulation is unobstructed.Air outlet 8
It can be grid, the wind direction of adjustable outlet air, top grid blows upwards, and grid on the lower is blown downwards, and angle gradually changes,
The path of cold wind is set uniformly to pass through the space of freezing chamber 20 as far as possible.Circulating fan 5 can be located at freezing chamber 20 left side or
Right side or rear side.It is cabinet door 19 on front side of freezing chamber 20.Blade is axial-flow leaf 7.Heater strip is set below axial blade 7, it can
To be used to equipment disinfection or be rapidly heated.Controller and operation instrument 6 is arranged in 20 side of freezing chamber.
Shaft 10 is driven by stepper motor 14, and stepper motor output shaft 12 or shaft 10 are arranged position sensor 13 and are used to
Determine the zero-bit that shaft 10 rotates, position sensor 13 and stepper motor 14 are electrically connected controller.Stepper motor 14 can pass through
Retarder slows down, to keep revolving speed more stable.If having retarder, the output in retarder is also can be set in position sensor 13
On axis.If not allowing easy to install in motor output shaft 12, reducer output shaft or shaft 10, diameter can be set on it slightly
On big turntable 15.Stepper motor 14 and position sensor 13 select low temperature resistant model.As described in Figure 1,14 He of stepper motor
