System and electric control system six part composition, food pre-freeze to be completed, drying sublimation, parsing these three ranks of distillation in freeze dryer
Section.The feature of lyophilizing refrigeration system is that load change is big, and initial temperature-fall period workload demand amount is few, and sublimation stage refrigeration requirement is anxious
Acute rise, subsequent resolution phase load is decreased obviously again, and different food, and different quantity all can lead to the difference of load
Different.At present application there is problems that：Due to load change frequently, refrigeration system liquid changes in flow rate can be led to big, if not
The liquid supply rate in each stage can accurately be controlled it is easy to lead to system to return liquid, lyophilizing goods quality is undesirable.
Content of the invention
The purpose of the present invention is exactly to propose a kind of freeze-drying system multichannel to freeze liquid feeding structure, to solve above-mentioned prior art
Present in problem.
For realizing the purpose of the present invention, the liquid feeding structure the invention provides a kind of freeze-drying system multichannel is freezed, including confession
Liquid supervisor, return-air supervisor, feed flow supervisor are divided into six road feed flow arms, every road feed flow arm install stop valve, drying successively
Filter, for according to lyophilizing cabin internal loading situation of change adjust feed flow branch road open and close electromagnetic valve, for by sense
Heating power expansion valve, stop valve to realize the regulation of the refrigerating capacity on the feed flow branch road of every road for the degree of superheat of thermometer bulb perception return-air supervisor.
Compared with prior art, beneficial effects of the present invention are, solve load and frequently change the liquid supply rate demand leading to
Change is big, system and returns liquid problem；Improve the quality of lyophilizing goods.
Brief description
Fig. 1 is the structural representation of the present invention；
In figure：1st, feed flow supervisor, 2, feed flow arm, 3, return-air supervisor, 4, stop valve, 5, device for drying and filtering, 6, electromagnetic valve,
7th, heating power expansion valve, 8, temperature-sensitive bag.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be appreciated that it is described herein

It should be noted that " connection " described herein and be used for expressing the word of " connection ", such as " being connected ",
" being connected " etc., both included a certain part and be directly connected to another part, and also included a certain part and pass through miscellaneous part and another portion
Part is connected.
It should be noted that term used herein above is merely to describe specific embodiment, and it is not intended to restricted root
Illustrative embodiments according to the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
Be also intended to including plural form, additionally, it should be understood that, when in this manual using belong to "comprising" and/or " bag
Include " when, it indicates existing characteristics, step, operation, part or module, assembly and/or combinations thereof.
It should be noted that term " first " in the description and claims of this application and above-mentioned accompanying drawing, "
Two " it is etc. for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that such use
Data can exchange in the appropriate case, so that presently filed embodiment described herein for example can be with except here
Order beyond those of diagram or description is implemented.Additionally, term " comprising " and " having " and their any deformation it is intended that
It is to cover non-exclusive comprising, for example, contain process, method, system, product or the equipment of series of steps or unit not
It is necessarily limited to those steps or the unit clearly listed, but may include clearly not listing or for these processes, side
Method, product or the intrinsic other steps of equipment or unit.
For the ease of description, space relative terms can be used here, such as " ... on ", " ... top ",

It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can phases
Mutually combine.
The feed flow technology as shown in figure 1, a kind of freeze-drying system of the application multichannel is freezed, including feed flow supervisor 1, return-air supervisor
3.Feed flow supervisor 1 is divided into six road feed flow arms 2, every road feed flow arm 2 is installed stop valve 4, device for drying and filtering 5, electricity successively
Magnet valve 6, heating power expansion valve 7, stop valve 4, adjust opening of feed flow branch road 2 solenoid 6 according to lyophilizing cabin internal loading situation of change
Open, thus adjusting refrigeration liquid supply rate.Refrigerating capacity on every road feed flow branch road 2 is adjusted and is perceived by the temperature-sensitive bag 8 of heating power expansion valve 7
The degree of superheat of return-air supervisor 3 is realizing.
The work running of the present embodiment is：Freeze-drying process is different, and desirable load is different.When workload demand amount is
When 100%, feed flow branch road 2 solenoid 6 is fully open, and liquid supply rate reaches maximum, realizes the fast cooling of lyophilizing under-deck cargoes thing.
When workload demand is reduced to 50%, the electromagnetic valve 6 on three road feed flow branch roads 2 is opened, and provides 50% liquid supply rate, meets cooling need
Ask, liquid will not be produced back.When workload demand is reduced to 15%, electromagnetic valve 6 on Zhi Kai mono- road feed flow arm 2, provide enough
Liquid supply rate, then the fine setting that return-air supervisor's 3 degrees of superheat carry out liquid supply rate is perceived by heating power expansion valve 7 temperature-sensitive bag 8, reach demand
Cooling-down effect, will not produce back liquid.
The above is only the preferred embodiment of the present invention it is noted that common skill for the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also should be regarded as protection scope of the present invention.
