Abstract
The invention relates to a freeze dryer special for a freeze drying piece of active factors. The freeze dryer special for the freeze drying piece of active factors comprises a freeze dryer box which is provided with a protective door; the freeze dryer box is connected with a cold trap circulating system; the cold trap circulating system and the freeze dryer box are both connected with a low-temperature heat exchanger which is connected with a gas and liquid separator; the gas and liquid separator is connected with a liquid nitrogen storage tank; and an ultraviolet sterilizer is installed on the upper portion in the freeze dryer box. The freeze dryer is simple in structure, scientific and reasonable in design, convenient to maintain and clean, good in sterilization effect, safer and more reliable.
Description
Technical field
The invention belongs to freeze dryer field, especially a kind of freeze dryer being exclusively used in active factors freeze-drying sheet.
Background technology
The Vacuum Freezing & Drying Technology that freeze dryer originates from the twenties in 19th century experienced by decades fluctuating and after hovering, made significant progress in last 20 years.Enter 21 century, the advantage that vacuum freeze drying technology relies on other drying means incomparable, more and more be subject to the favor of people, except being used widely in medicine, biological products, food, blood product, active material field, its application scale and field are also in constantly expanding.For this reason, vacuum freeze drying will become the important application technology of 21 century, although existing freeze dryer can realize freeze-drying function, maintenance cleaning is not easy to remove totally, especially sterilizing aspect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of freeze dryer being exclusively used in active factors freeze-drying sheet, this freeze dryer structure is simple, and design science is reasonable, and safeguard that cleaning is convenient, sterilization effect is good, more safe and reliable.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of freeze dryer being exclusively used in active factors freeze-drying sheet, comprise a body of freeze dryer, this casing is provided with protective door, body of freeze dryer connects the cold-trap circulatory system, its cold-trap circulatory system is connected cryogenic heat exchanger respectively with body of freeze dryer, this cryogenic heat exchanger connects gas-liquid separator, and this gas-liquid separator connects liquid nitrogen storage tank, above body of freeze dryer inside, be provided with ultraviolet sterilizer.
And, described protective door is provided with vacuum meter.
And bottom is provided with heater in described body of freeze dryer.
And, be plugged with dividing plate in described body of freeze dryer, the uniform setting of this dividing plate.
Advantage of the present invention and beneficial effect are:
Originally the freeze dryer of active factors freeze-drying sheet is exclusively used in, comprise a body of freeze dryer, this casing is provided with protective door, body of freeze dryer connects the cold-trap circulatory system, its cold-trap circulatory system is connected cryogenic heat exchanger respectively with body of freeze dryer, this cryogenic heat exchanger connects gas-liquid separator, this gas-liquid separator connects liquid nitrogen storage tank, above body of freeze dryer inside, ultraviolet sterilizer is installed, this freeze dryer structure is simple, and design science is reasonable, safeguards that cleaning is convenient, sterilization effect is good, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of freeze dryer being exclusively used in active factors freeze-drying sheet, comprise a body of freeze dryer 3, this casing is provided with protective door 2, body of freeze dryer connects the cold-trap circulatory system 8, its cold-trap circulatory system is connected cryogenic heat exchanger 7 respectively with body of freeze dryer, this cryogenic heat exchanger connects gas-liquid separator 9, and this gas-liquid separator connects liquid nitrogen storage tank 10, is provided with ultraviolet sterilizer 5 above body of freeze dryer inside.Protective door is provided with vacuum meter 1.In body of freeze dryer, bottom is provided with heater 6.Dividing plate 4 is plugged with, the uniform setting of this dividing plate in body of freeze dryer.This freeze dryer changes based on the tri-state of water.Water has solid-state, liquid and gaseous state, and three kinds of states not only mutually can be changed but also can be coexisted.When water is when three phase point (temperature is 0.01 DEG C, and water vapor pressure is 610.5Pa), water, ice, steam three can coexist and mutually balance.Under high vacuum state, utilize sublimation principle, make the moisture in the material freezed in advance, without the thawing of ice, directly distil as water vapour is removed with ice state, thus reach cryodesiccated object.
Claims (4)
