Abstract
The present invention relates to a forced ventilation type sterilizer for flexible package. An axial flow fan is arranged on the top of a sterilizing chamber, and a condenser coil assembly is arranged on the side wall of the sterilizing chamber. A sliding door mechanism of a sterilizer comprises an air-tight door, a front close board, a joint shaft and a seat board for a joint door. The present invention is suitable for the high temperature sterilization of liquid preparation packed in a plastic bottle or a plastic bag. In the process of sterilization, temperature in a sterilization box is uniform, and temperature error is one degree centigrade; the deformation rate of the plastic bottle and the breakage rate of the plastic bag are near zero, sterilization is thorough, and the present invention puts an end to the phenomenon of medicine degenerescence; the plastic bottle and the plastic bag which are sterilized are fast cooled and dried, the surface of the plastic bottle and the surface of the plastic bag do not have water damage, and the present invention is favorable for fast lamp examination, package and storage and remarkably improves production efficiency.
Description
Technical field
The invention belongs to steam sterilization equipment, relate to a kind of forced ventilation flexible package sterilizer.Be applicable to high temperature sterilize use (PE or PP plastic bottle, PVC or non-PVC plastics are packed), be particularly useful for the steam sterilization of common transfusion class preparation under 105～127 ℃ of temperature and use with the liquid preparation of plastic bottle, plastic bag packaging.
Background technology
Steriliser is cooled off in flexible package fast in the prior art, is the steam sterilization equipment that the nineties grows up, and is applicable to hospital preparation.But its sterilising temp is inhomogeneous, and everywhere the temperature difference is bigger in the sterile chamber; The temperature, pressure equilibrium point is difficult to control during sterilization, very easily makes plastic bottle, plastic bag distortion or explosion when sterilization of packing liquid preparation; Plastic bottle, plastic bag surface water easy-storing stain were unfavorable for lamp inspection and package handling after sterilization treatment finished.Above-mentioned all factors do not meet GMP (Good Manufacturing Practice, the pharmaceutical production management regulation) requirement of country to the pharmaceutical industry production process, can not provide aseptic assurance to the liquid type medicine preparation of being sterilized.
Summary of the invention
Purpose of the present invention, be to solve all drawbacks that above-mentioned prior art exists, uniformity of temperature profile everywhere in sterile chamber when a kind of operation is provided can be cooled off after sterilization finishes and dry fast, guarantee product quality, the forced ventilation flexible package sterilizer of enhancing productivity.
Technical scheme of the present invention is: design a kind of forced ventilation flexible package sterilizer, the hermatic door that comprises steam sterilization chamber and its two ends, it is characterized in that steam sterilization chamber top portion multiple spot is provided with a plurality of axial flow blowers, the impeller of axial flow blower is arranged on sterile chamber's inner top; Sterile chamber's double side wall is provided with many group condenser coil assemblies; The hermatic door at its two ends is a sliding door mechanism.Its steriliser sliding door mechanism comprises hermatic door 3, preceding shrouding 10, take axle 7 and take gate seat plate 6, hermatic door 3 one side settings are taken axle 7 opposite sides jack 11 are set, Dui Ying preceding shrouding 10 1 sides are provided with jack 11 opposite side settings and take axle 7 with it, hermatic door 3 carryings are slided to be fixed on and are taken on the gate seat plate 6, hermatic door 3 peripheries are inlaid with rubber weather strip 9, and rubber weather strip 9 is provided with filling channel 8 with hermatic door 3 peripheral clearance places.Its bottom, sterile chamber is provided with an air inlet at least.
The present invention compared with prior art has tangible advantage:
1. through the test of 16 temperature polling instruments, uniformity of temperature profile everywhere in the sterilization tank in the sterilization process, error ± 1 ℃;
2. plastic bottle deformation rate, plastic bag breakage rate level off to zero, sterilize thoroughly, stopped the medicine denaturalization phenomenon;
3. sterilization treatment finishes, and back plastic bottle, plastic bag are also dry by quick cooling, the surface is no water stain, are beneficial to quick lamp inspection and put in storage with packing, significantly improve production efficiency.
Description of drawings
Below in conjunction with accompanying drawing and practical application, the present invention is further elaborated:
Fig. 1 is the structural representation (an end steriliser hermatic door opening) of one embodiment of the invention;
Fig. 2 is the B-B cutaway view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
Application example:
Steriliser hermatic door at the aseptic condition end (is constructed equally with the hermatic door 3 of operating side, not shown) close, under the prerequisite that the hermatic door 3 of operating side is opened, to use plastic bottle, the liquid preparation subject to sterilization of the plastic bag packaging disinfecting car of packing into successively, disinfecting car is pushed in the sterile chamber 4 from the operating side hermatic door of opening 3, drive the hermatic door 3 of operating side, it is slided until the jack 11 that axle 7 opposite sides are provided with of taking of hermatic door 3 one side settings, lock with the axle 7 corresponding one by one grafting of taking of the jack 11 opposite side settings of corresponding preceding shrouding 10 1 side settings, rubber weather strip 9 and corresponding preceding shrouding 10 butt joints that steriliser hermatic door 3 peripheries are inlayed, open source of the gas shrouding 10 before filling channel 8 is pressed to rubber weather strip 9, make operating side steriliser hermatic door 3 and corresponding preceding shrouding 10 sealings, the air inlet that is provided with from bottom, base 5 sterile chambers feeds steam in sterile chamber 4, in the heating period of sterilization process, steam, air or both mists, through a plurality of axial flow blowers 1, convection circulation between flexible package product subject to sterilization in the sterile chamber forcibly is for the heating period provides equally distributed temperature environment.
In whole sterilization process, adopt technology such as pressure tracking, back-pressure control, between the saturated vapor pressure of liquid a positive difference corresponding relation is arranged in pressure in the assurance sterile chamber 4 and the flexible containers under this temperature, this has just guaranteed in whole sterilization process, the pressure of flexible containers outside guarantees that all the time greater than its pressure inside flexible containers can not expand and explosion because of intrinsic pressure.
After the sterilization of heating finishes, steam off, to sterile chamber's sidewall condenser coil assembly 2 logical cooling waters are set, make the residue vapor in the sterile chamber 4 be condensed into water droplet, filtered air replaces steam, is continuing to force to carry out heat exchange under logical cooling water and the force ventilated condition, make the liquid preparation cooling, the flexible containers dry tack free.Subsequently, stop cooling water, compressed air and blower fan, dry run finishes, open the steriliser hermatic door of aseptic condition end, pull out the disinfecting car of the liquid preparation that plastic bottle, plastic bag packaging are housed, carry out lamp inspection and packing warehouse-in, effect satisfaction has reached the goal of the invention of expection.
