The sterilization machine filled with high-temperature pressure vessels --- hot barrels, as pressure steam. The main setting is outside the barrel-shaped double spiral casing, used as a right of entry, exit of hot and cold materials exchange; barrel of the main settings spiral single-tube, used as an indirect heat.
Materials, sterilization processes: material through the feed pump into the pairs of sets of the outer flow channel coil, the heat flow from the inner layer material obtained indirect heating preheating, when the material is set into the barrel at high temperatures the heat coil, the due to an indirect steam heated barrel was heated to the desired sterilization temperature, and then barrel outside the single-coil inside the thermal insulation material Er Shi was to kill bacteria, when the return to double-sets of coils, the material will enter the inner flow channel, by the outer cold by the cooling material and thus exert a significant decline in feed temperature (generally less than 65 ). Such as the craft need to raise or lower the discharge temperature, to enable angle-type stop valve so that it connected to the heat source (steam) or heat (water or ice water, etc.) allow them to enter the double bottom of the outer casing flow channel.
Throttle valve can be adjusted on the one hand so that materials be maintained at a certain pressure, to the boiling point temperature rises, and in order to prevent vaporization: the other hand, also used for regulating flow. In addition to the final by three cocks materials materials. The cocks, and then the bottom of coils, their exports would be a tank, when necessary, may be rotating coil alignment overflow pipe. Feed the upper three cocks connected with the tank, the bottom of the pipe connected with the source material.
When you need to increase processing capacity, they can shed a "U"-shaped tube divert a centrifugal pump.
This machine is a hand-control-type sterilizing machine, sterilization temperature by angle-type stop valve to adjust the temperature can be expected out of angle-type stop valve to change. Steam pressure gauge, thermometer, and a sterilization material thermometers were installed in the host.
Installation and Adjustment
The device has two high-temperature barrel roof is prepared for hoisting rings are used, but it can be seen lifting to the roof.
- the device placed in the shop flat land aerodromes without equipment foundation.
- the equipment installation, support angle adjustable four bolts, branch angle must be floor contact, feeding pump 4 feet and ground floor access to the same request, the level of pump shaft must be corrected to prevent the use of vibration occurs.
- all devices connected to this pipe should be careful not to allow equipment subject to any external force, in particular, should be to eliminate thermal expansion effects.
- feed pumps must ensure the correctness of the direction of motor drive: operators face impeller, pump shaft should be counter-clockwise rotation, installed after manually rotating shaft is flexible.
- in the steam at the entrance must be connected to 0.78Mpa (8Kgf/cm2) safety valve.
- when the use of homogeneous machines, the user-access channels should be 14.7Mpa (150Kgf/cm2) pressure test shall not be leaking.
- tank overflow pipe inside the trench must be connected to prevent the washing liquid corrosion damage to shop on the ground.
