Bacteria are enemy of brewery beer flavor production, made in mechanical equipment co., LTD., jinan small make up today is to introduce in detail for you brewery production equipment using the main kinds of fungicides, let you know more about beer production how to sterilization.



1. Chlorine (sodium hypochlorite) has wide spectrum, hard water resistance and low temperature effect. The price is relatively cheap, and the residue activity is used. The disadvantage is that it can form toxic chlorine gas, which is dangerous. In addition, the utilization rate as a fungicide will corrode the equipment pipeline, and it is also stimulating. Excessive residue can shorten the shelf life of beer, and may also form the effect of trichloromethane on the flavor of beer.

2. Iodine has a wide spectrum, which is less irritating than chlorine and has a pH range of 2-8, with a longer sterilization period. The color of iodine solution provides visual control, which can be used to determine the validity period. The disadvantage of iodine is that it will stain the porous and plastic equipment, which will corrode the equipment piping at high temperature, which is more expensive than chlorine and has bad odor.

3. Quaternary ammonium salts are nontoxic, odorless, colorless, non-corrosive, and stable in temperature. They are relatively stable in organic solutions and have broad spectrum and residual antimicrobial resistance. The disadvantage of quaternary ammonium salt is that it is not compatible with the humidifying compounds containing anions, low resistance to hard water, limited low temperature activity, and excessive foaming in the CIP system.

4. Hot water (steam) has broad spectrum, easy to obtain, non - toxic, non - corrosive, and has good permeability. The disadvantage of hot water (steam) is that it is easy to form film, slow heating and energy consumption.

5. Chlorine dioxide is a powerful oxidant, and the sterilization efficiency is high, especially the sterilization of space, which has a long function time and relatively low cost, which is widely used by most breweries. Its disadvantage is that if it is not measured correctly, it will cause security problems. In addition, high concentration of chlorine dioxide is corrosive to stainless steel equipment.

Great opportunities: in the year craft beer standard and related laws and regulations, the new policy will integrate current policy, the small craft beer filling beer can be formally to market, craft beer industry will usher in the healthy development of opportunity!
