Solar sterilization device

Abstract

The invention discloses a solar sterilization device which comprises a solar heat collector and a steam sterilizer, wherein the solar heat collector is communicated with a heat exchange pipe arranged in the steam sterilizer through a liquid conveying pipeline. The solar sterilization device realizes the sterilization work based on regenerative energy, is suitable for steam sterilization work on medical instruments, packaged food, beverage and the like and can realize the automatic control in the whole sterilization process; the labor intensity is greatly reduced, and the production efficiency is improved; the solar sterilization device is extremely high in quality stability and use safety and reliability, and very easy to operate.

Description

technical field [0001] The invention belongs to the technical field of steam sterilization and relates to a solar sterilization device. Background technique [0002] With the development of society, steam sterilizers are used more and more widely, especially in the fields of sterilization of medical appliances and production of sealed packaged food. Traditional steam sterilizers usually use electricity or non-renewable fuels to produce steam, which is then passed into a pressure vessel for sterilization of the product to be treated. Its main defects are: 1) The steam sterilizer is a high-energy-consuming equipment that requires a large amount of non-renewable energy consumption. With the rapid attenuation of energy resource reserves and the increase of mining costs, it will bring social energy tension and sterilization costs 2) The sterilized items need to go through the process of pressurized heating and natural cooling with the furnace in the sterilizer, especially the na...

Problems solved by technology

Its main defects are: 1) The steam sterilizer is a high-energy-consuming equipment that requires a large amount of non-renewable energy consumption. With the rapid attenuation of energy resource reserves and the increase of mining costs, it will bring social energy tension and sterilization costs 2) The sterilized items need to go through the process of pressurized heating and natural cooling with the furnace in the sterilizer, especially the natural cooling speed is slow, so the production efficiency is low, and it is difficult to meet the needs of large-scale industrial production; 3) Sterilization Most bacteria items are sterilized in a sealed package. During the cooling process, due to the inconsistent temperature drop rate inside and outside the package, there is a difference in internal and external pressure, which can easily lead to damage to the package, resulting in rework and waste of materials; 4) due to the cooling A large amount of condensed water is produced during the process, which accumulates in the sterilization chamber and soaks the sterilized items, and then needs to increase the drying process, which brings about the extension of the production cycle and the waste of labor and energy; 5) Most of the sterilization process relies on manual operation based on experience , so there are poor stability and reliability of sterilization quality assurance, low operating safety factor, and easy to cause personal injury accidents

This technology solves the problems of accelerating sterilization heating and cooling time and reducing labor intensity, but it still cannot fundamentally solve the above-mentioned problems existing in traditional sterilizers
