Nitrogen protection machine for coffee nitrogen generator
What is the role of nitrogen in coffee packaging applications?Bulk coffee storage cleaningRoasting beans enhances the flavor and aroma of coffee. After the beans are roasted, they need to be stored in an enclosed storage facility, such as a silo. Controlling the amount of oxygen in the storage area is important because excessive exposure to oxygen can deplete the aroma and flavor characteristics of roasted beans.Nitrogen can help counteract and prevent the negative effects of excessive exposure to oxygen, while also controlling the amount of oxygen in storage, packaging, and transportation facilities. To maintain the quality of coffee beans, oxygen levels in storage facilities need to be 1% or less. On-site nitrogen generators for coffee bean storage can help generate a steady stream of nitrogen to replace oxygen in the storage area, thus maintaining high product quality over the long term by keeping the beans fresh and preventing the natural oils in the beans from reacting with ambient oxygen that, over time, rots.Nitrogen rinse in coffee packagingNitrogen flushing is widely used in coffee production and packaging.In the production of coffee bags, K-cups, and larger storage tanks or bags, the supply of food-grade quality nitrogen using an on-site nitrogen generator is the most cost effective form of nitrogen supply for atmospheric flushing. After rinsing with nitrogen, the coffee product is sealed with little oxygen in the package. This atmosphere will greatly extend the freshness of coffee products and product shelf life.Nitrogen charging coffeeNitrogen-infused coffee, also known as nitro cold-brewed coffee or simply cold-brewed coffee, is the latest development in the industry. Pressurized nitrogen or a mixture of carbon dioxide and nitrogen is injected into a frozen VAT of traditional brewed coffee. Consumed directly in the same way as beer, nitrogen infused coffee typically has a smoother and less bitter flavor than regular iced coffee, without enhancers such as cream or sugar. The on-site nitrogen generator can provide the necessary nitrogen.

 

At low temperature and high pressure, nitrogen will dissolve into the coffee, once back to atmospheric pressure, will release a large number of tiny bubbles, foam like cold fog floating in the coffee, eventually forming a dense foam like Espresso.(Dynamic diagram of foam formation)Nitrogen adds fullness and texture to coffee compared to unaerated coffee.Nitrogen coffee is made in two step"Coffee Preparation" and "Nitrogen Incorporation"The process of making coffee is very mature, and adding nitrogen is not complicated. It just requires some special equipment.So, let's talk about how to make a cup of nitrogen coffee --Everyone likes different flavors.I'm a homebrewer and once collaborated with my coffee roaster friend Renaud on a coffee beer.The first time I used a light, sour baked peyega chaffee, which I didn't call beer at all, but Reynaud liked it very much.The second time, he used a medium depth of Mantinim and reduced the ratio to a malt and hop flavor, but Reynaud felt that the fruit acid was completely missing.So, as far as a drink is concerned, which flavor is better, it depends on you.Low flavorThe effect of nitrogen is more on the taste rather than changing the flavor too much. But if a mixture of gases is used for gasification, it needs to be adjusted according to the specific gas characteristics.Production methodThe mainstream nitrogen coffee production method is mainly cold extraction. After a long time of low temperature extraction, the coffee powder dissolves the oils and aromatic substances containing flavor, avoiding the undesirable flavor produced by high temperature combination reaction. Ice drops and ice brew are good choices.In addition, some baristas use Espresso to make nitrogen coffee. The Espresso is thicker, and nitrogen will make it produce the effect of milkshake. The experience is completely different, and the production is more time-consuming.Low gasNitrogen coffee generally uses "pure nitrogen" or "nitrogen - carbon dioxide mixture".Both of these food-grade gases are available at the Universal TB.But manufacturers generally do not sell the mixture directly, so they have to buy an extra tank of carbon dioxide and mix the proportions themselves.Low pure nitrogenNitrogen is usually insoluble in water, unless you use a low-temperature, high-pressure container to deal with it, and once it's free, it immediately becomes insoluble again.But don't worry, pure nitrogen doesn't erupt like Coke. Even when shaken violently, it will only slowly form a cloud of bubbles that slowly rise to form a thick white foam.Pure nitrogen (99.999%) is colourless, tasteless and does not change the flavor of coffee except for the taste. It is safe and non-toxic.oxygen-carbon dioxide mixtureThis gas mix was first used in nitrogen beer, where carbon dioxide is an essential ingredient that quickly takes heat away from the body and makes you feel cooler. Nitrogen enhances the depth of beer, giving beers like Milk-Shitao a smoothness close to that of milk.Those of you who have made carbonated soda know that carbon dioxide can give you a bit of a sour taste. This sour taste is not necessarily a bad thing. If you want to experience it, buy a bottle of Coke, pour half of it out, and then use your ancient powers to shake the bottle until it is empty. By comparing two glasses, you can see the difference between Coke and sugar water.The ratio of gas is recommended to be maintained at 7:3, with 7 nitrogen and 3 carbon dioxide. The more nitrogen, the more delicate the foam will be. The more carbon dioxide, the more carbonated the foam will be and the thicker the foam will be. If the use of pure carbon dioxide, it became carbonated coffee, interested in friends might as well try.In addition, when carbon dioxide volatilization is more intense, it is best to use the "cup wall down" method to avoid wet body.After knowing the characteristics and differences of raw materialsLet's see how nitrogen coffee is madeFirst we need a pressurized KEG bucket to prepare 2 liters of filtered water.After sealing the jars, they were cooled in the refrigerator to 6 ° C, which is close to freezing and meets the requirements of low-temperature extraction. Cooling time is slightly longer, it is best to prepare one day in advance.Once the water temperature is reached, you can start making the coffee filter bag. At a ratio of 12:1, two liters of ground 166g coffee can be slightly coarser.Here is the use of non-woven filter bag, sealed with a heat sealing machine. You can also use a tea filter bag, but because the tea filter paper is very easy to damage, the coffee grounds blocked the wine hole this pot will be useless, so it is necessary to set two layers, to a double insurance.- Double cover -Put the coffee bag in, close the lid, and begin to fill the air. The goal is to drain the oxygen, maintain the flavor of the coffee, and check air tightness.Return to the fridge and leave for 48 hours.After extraction, remove the coffee bag.Three charge three release again, the formal start of gasification.Gasification requires a certain pressure, which can only be observed with the help of a barometer.There are three types of barometers on the market: Mpa, Kpa, and Bar.1 mpa = 1000 kpa = 10 bar.We need the pressure to be stable at 0.2mpaSo that's 200Kpa or 2 barsontinue to put it into the refrigerator. Under the action of low temperature and high pressure, the gas will be continuously blended into the coffee. It is necessary to replenish the gas regularly and keep the air pressure at 0.2mpa until the air pressure does not drop.- sampling -Stored in the freezer, the cold temperature can prolong the flavor period. Output through the pipe to the Tap, if there is a pipe refrigerator, the effect will be more perfect.There is also a way to make it over ice, which is cooler but affects the strength and foam of the coffee. Ice can be abandoned with a refrigerator or piped refrigeration unit.

 

PSA Nitrogen Generator full name: Pressure Swing Adsorption (PSA).PSA is a new gas separation technology, which has been developed rapidly in foreign countries since the late 1960s and early 1970s. Its principle is to separate the gas mixture by the difference of the "adsorption" performance of different gas molecules by molecular sieve. It takes air as raw material.The nitrogen and oxygen in the air are separated by the selective adsorption of nitrogen and oxygen with a high efficiency and high selection of solid adsorbent.

At present, carbon molecular sieves and zeolite molecular sieves are used more in the field of nitrogen and oxygen production.The separation of oxygen and nitrogen by molecular sieve is mainly based on the different diffusion rates of the two gases on the surface of molecular sieve. Carbon molecular sieve is a carbon-based adsorbent with some characteristics of activated carbon and molecular sieve.Carbon molecular sieves are composed of very small micropores with pore sizes ranging from 0.3nm to 1nm.The smaller diameter of the gas (oxygen) diffuses faster and more into the solid phase of the molecular sieve, so that nitrogen enrichment can be obtained in the gas phase.After a period of time, molecular sieve on oxygen adsorption balance, according to the carbon molecular sieve under different pressure on the adsorption of different gas adsorption characteristics, reduce the pressure to remove the carbon molecular sieve on oxygen adsorption, this process is called regeneration.PSA usually uses two towers in parallel, alternately pressurized adsorption and decompression regeneration to obtain a continuous flow of nitrogen.

With air as raw material, with carbon molecular sieve as adsorbent, the use of pressure change adsorption principle, the use of carbon molecular sieve on oxygen and nitrogen selective adsorption and separation of nitrogen and oxygen method, commonly known as PSA nitrogen.This method is a new technology of nitrogen production which developed rapidly in 1970s.Compared with the traditional method of nitrogen, it has simple process, high degree of automation, produce gas quickly (15 ~ 30 minutes), low energy consumption, product purity can be adjusted according to user needs in a wide range, convenient operation and maintenance, low operating cost, good adaptability device etc., in 1000 nm3 / h the following competitive in nitrogen making equipment,PSA is more and more popular among medium and small nitrogen users, and has become the choice method for medium and small nitrogen users.

1. Why choose PSA nitrogen generator ?High purityPSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide - up to 99.9995% nitrogen.The nitrogen generators use CMS (carbon molecular sieve) technology to produce a continuous supply of ultra high purity nitrogen and are available with internal compressors or without.Low operating costsBy substitution of out-of-date air separation plants nitrogen production savings largely exceed 50%. The net cost of nitrogen produced by nitrogen generators is significantly less than the cost of bottled or liquefied nitrogen.Nitrogen Generators Create Less Impact on the EnvironmentGenerating nitrogen gas is a sustainable, environmentally friendly and energy efficient approach to providing pure, clean, dry nitrogen gas. Compared to the energy needed for a cryogenic air separation plant and the energy needed to transport the liquid nitrogen from the plant to the facility, generated nitrogen consumes less energy and creates far fewer greenhouse gases.Nitrogen protection machine for coffee nitrogen generator

LDHGAS psa nitrogen making machine process and equipment introduction1. The technological process of nitrogen generator is briefly introducedAir through the air filter to remove dust and mechanical impurities into the air compressor, compressed to the required pressure, after strict oil removal, water removal, dust removal and purification treatment, output clean compressed air, the purpose is to ensure the service life of the molecular sieve. At work, one pot adsorption, the other pot desorption, two sub work alternately. Clean air into the working adsorption tower, through molecular sieve oxygen, carbon dioxide and water absorption, flow to the outlet end of the gas is nitrogen and trace argon and oxygen. In this way, the two towers take turns to separate nitrogen and oxygen and continuously output nitrogen. The purity of nitrogen produced by psa is 95% to 99.999%.
