Alcohol brewing and blending reverse osmosis equipment, pure water equipment
Reverse osmosis equipment, pure water systems, pure water equipment for brewing, and water treatment equipment for liquor blending used in the distillery industry
In Baijiu, water and ethanol are the main components, accounting for about 97% of the total, while water generally accounts for more than 55%. At present, water accounts for about 80% of the low alcohol wines newly developed by various renowned distilleries. From this point of view, the role of water in liquor is extremely important. It can be said that excellent water quality is a key factor to improve the quality of famous and high-quality Baijiu. Brewing requires good water, and the water used for blending has higher requirements for water quality. If the water source is not selected and controlled; Not performing necessary post-treatment on water will inevitably have a significant impact on the flavor of the finished wine. Our company has adopted a reverse osmosis system to treat blending water and achieved good results. We would like to discuss this with our peers in the industry.
The basic requirement for blending water is that the total hardness should be less than 1.783mol/l;
1.1 Low salinity, total salt content less than 100mg/L. Since trace inorganic ions are also components of Baijiu, distilled water should not be used as the water for alcohol reduction.
1.2 NH3 content below 0.1mg/L
1.3 Iron content below0.1mg/L
1.4 Aluminum content below0.1mg/L ,
1.5 There should be no corrosive decomposition products. Dissolve 10mg potassium permanganate in 1L of water. If the color completely fades within 20 minutes, this water cannot be used as a cooling water.
1.6 ConductivityLess than 20us/cm
2. The working principle of reverse osmosis
Penetration is a physical phenomenon. When two types of water containing different concentrations of salts are separated by a semi permeable membrane, it is found that the water on the side with less salt content will permeate through the membrane to the water with higher salt content, while the salt content does not permeate. In this way, the salt concentrations on both sides gradually merge until they are equal. This process is called natural infiltration. Reverse osmosis is a separation method that separates solutes and solvents in a solution under pressure, using the selective retention effect of a semi permeable membrane. It consists of a pure water system for the distillery industry, a pure water equipment for brewing, and a water treatment equipment system for liquor blending; Reverse osmosis equipment is a water treatment system organized around a reverse osmosis membrane. A complete reverse osmosis system consists of a pretreatment section, a reverse osmosis host (membrane filtration section), a post-treatment section, and a system cleaning section.
Pre treatment often consists of quartz sand filtration device, activated carbon filtration device, and precision filtration device. The main purpose is to remove harmful substances such as sediment, rust, colloidal substances, suspended solids, pigments, odors, and biochemical organic matter contained in raw water, reduce residual ammonia value and pesticide pollution in water. If the content of calcium and magnesium ions in the raw water is high, it is necessary to add a soft water device, mainly to protect the reverse osmosis membrane in the later stage from damage by large particles, thereby extending the service life of the reverse osmosis membrane.
The reverse osmosis host is mainly composed of a booster pump, membrane housing, reverse osmosis membrane, control circuit, etc. It is the core part of the entire water treatment system, and the quality of the produced water mainly depends on this part. As long as the model of the membrane and the model of the booster pump are selected properly, the filtration capacity of the reverse osmosis host for salt in water can reach over 99%, and the effluent conductivity can be guaranteed within 10us/cm. The post-treatment part mainly involves further processing of the pure water produced by the reverse osmosis host. If ion exchange or electro deionization equipment is connected to the subsequent process, industrial ultrapure water can be produced. If it is used in the process of direct drinking water for civilian use, it is often connected to a post sterilization device, such as a paper external sterilization lamp or ozone generator, so that the water can be directly consumed.
Characteristics of pure water equipment used in the brewing industry of our company's distillery
The equipment usually consists of a multi-media filter, activated carbon filter, sodium ion softener, precision filter, etc., which form the main equipment system, including the pre-treatment system and reverse osmosis host system. The water tanks are equipped with liquid level control systems, the water pumps are equipped with pressure protection devices, online water quality detection and control instruments, and programmable controllers are used for electrical systems, truly achieving unmanned operation. At the same time, the recommended and customer required methods are adopted for process material selection, making the equipment more cost-effective and reliable compared to other similar products
