Description
Technical field
The present invention relates to a kind of powder disinfection system, especially a kind of superheated vapor vacuum powder disinfection system.
Background technology
Generally using steam sterilizing in drug and food processing, traditional steam sterilization generally comprise low high temperature it is long when
Sterilization, sub- high temperature short time and ultra high temperature short time sterilization method, no matter which kind of mode, sterilization process is required for occupying
Longer time, and powder often can all destroy the active ingredient of drug and food powders in the condition of high temperature for a long time, for
The above problem, applicant have declared invention and utility application on 31st in August in 2016 to State Intellectual Property Office,
In, the open notification number of patent of invention is CN106267253A, and the Authorization Notice No. of utility model is CN206404058U, by height
Warm sterilization time is shortened between 5-120s, effectively reduces destruction of the high-temperature sterilization time to powder active ingredient.
In follow-up Development Practice, applicant thinks that sterilising temp high temperature needs 130-250 DEG C of still higher, sterilization time
Still partially long between 5-120s, these factors all may generate destruction, energy to the active ingredient in drug or food powders
It is no that sterilising temp lowers while sterilization effect is not influenced, the high-temperature sterilization time was shortened within 5 seconds, this has become
For the new objective of the struggle of applicant and a kind of expectation of this field.
The content of the invention
It is an object of the present invention to it is for the open notification number of the patent of invention of applicant's earlier application
CN106267253A, the Authorization Notice No. of utility model is sterilising temp existing for CN206404058U is higher and sterilization time
The technical issues of powder active ingredient still may be destroyed more than 5s, after the local improvement of earlier application, provides a kind of new
Superheated vapor vacuum powder disinfection system.
The object of the present invention is achieved like this：A kind of superheated vapor vacuum powder disinfection system, including storage tank, split
Formula sterilization tank, rotation axis of ventilating, have more stomata agitating paddle, precise powder filter screen, pneumatic operated valve, negative-pressure air fan, superheated steam valve,
Rotary joint, sterile high pressure wind inlet, discharge port, which is characterized in that the negative-pressure air fan passes through pipeline and precise powder mistake
Strainer is docked with split type sterilization tank, and one group of vacuum tank is further included in system, is set on one group of vacuum tank there are two interface, one connects
Mouthful by the pipeline joint between pipeline and the pneumatic operated valve and precise powder filter screen, vacuum valve and essence are equipped in the road pipeline
Close filter, another interface are docked by pipeline with vacuum pump or vacuum generator, and filter is equipped in the road pipeline；Vacuum
The volume of tank is at least 2 times of split type sterilizing tank volume.
In the present invention：Storage tank is furnished with adjustable speed motor and feeding screw, between storage tank and split type sterilization tank
Pneumatic feed valve, quantitative storage tank, air-actuated feeding valve and piston seal valve are equipped with successively, and quantitative storage tank is furnished with containing solenoid valve
High Pressure Air Pipe Line.
In the present invention：One group of vacuum tank includes at least two independent vacuum tanks, after their serial or parallel connections
Total measurement (volume) be at least split type sterilizing 2 times of tank volume, the temperature of the superheated vapor of ventilation rotation axis injection is 110-180
DEG C, sterilization time 0.5-5s.
In the present invention：The ventilation rotation axis by bearings on the central axes of split type sterilization tank, it is described
Bearing be also equipped with sealing ring.
In the present invention：Storage tank, split type sterilization tank, have more stomata agitating paddle, pneumatic operated valve, overheat at rotation axis of ventilating
Steam valve, rotary joint and pipeline and pipeline are made of stainless steel or titanium alloy material.
The advantage of the invention is that：Due to further including one group of vacuum tank in system, set on one group of vacuum tank there are two interface,
The negative-pressure air fan is docked by pipeline and precise powder filter screen with split type sterilization tank, an interface of one group of vacuum tank
By pipeline and negative-pressure air fan by the pipeline joint between pipeline and precise powder filter screen, this structure may insure split
Vacuum state is preset in after powder entrance in formula sterilization tank, powder is in split type sterilization tank in the environment that vacuum degree is higher
In, the grain size many bigger than bacterium of powder, and bacterium is mainly attached to the surface of powder, bacterium also contains moisture in vivo,
Since the boiling point of hydrone in vacuum environment is relatively low, it is only necessary to 110-180 DEG C of superheated steam is provided, when relatively low high temperature
Superheated steam is rapidly injected by rotation axis of ventilating in vacuum sterilization tank, and bacterium is touching the in vivo in a flash of superheated steam
Moisture boiling is got up, and bacterium bursts due in vivo moisture seethes with excitement, and the very of short duration duration of such sterilization time was at 0.5-5 seconds
Between, it is possible to the effect identical with earlier application is obtained, so as to be avoided in terms of sterilising temp and sterilization time two
To being sterilized the active ingredient and appearance color of powder-product.
It is also an advantage of the present invention that since quantitative storage tank is furnished with the compressed air pipe of solenoid valve, it can be quantitative
Air-operated piston valve below storage tank opens moment and is rapidly spurted into powder atomization shape in split type sterilization tank by pressure-air
Chamber.Since the volume of vacuum tank is at least split type sterilizing 2 times of tank volume, it can be ensured that split type sterilizing tank volume have compared with
High vacuum degree disclosure satisfy that the bacterium demand that internal water is seethed with excitement under relatively low high-temperature vapour.Outside due to split type sterilization tank
Wall is equipped with insulating layer, can prevent from hyperthermia and superheating gas from causing split type sterilizing that tank wall temperature is excessively high burns to operator.Due to
Each access port of split type sterilization tank is equipped with piston seal valve, in the state that split type sterilization tank inside and outside differential pressure is larger
Under, it can be ensured that obtain preferable sealing effect.
It is also an advantage of the present invention that：Due to storage tank, split type sterilization tank, rotation axis of ventilating, have more stomata agitating paddle,
Pneumatic operated valve, superheated steam valve, rotary joint and pipeline and pipeline are made of stainless steel or titanium alloy material, can be prevented
Pollution of the oxide impurity to powder, due to being equipped with precise powder filter screen in the pipeline of negative-pressure air fan, vacuum tank pipeline is with bearing
Also is provided between pressure fan pipeline precise powder filter suspended powder can be prevented in split type sterilization tank by negative-pressure air fan or
Vacuum pump is discharged into outside air.
The present invention is compact-sized, easy to maintain, due to being equipped with air-actuated feeding between quantitative storage tank and split type sterilization tank
Valve and piston seal valve, it can be ensured that quantitative sealing effect between storage tank and split type sterilization tank.Due to reducing overheat
The operating temperature and sterilization time of steam can reduce job costs and improve work efficiency.
