Use 95% to 98% pure nitrogen produced by the nitrogen generator to replace (dilute) the gas in the air-conditioning storehouse and reduce the concentration of oxygen in the storehouse. It can also be used to eliminate excessive carbon dioxide, ethylene, or other in the small air-conditioning storehouse. gas. At present, there are two types of nitrogen-dividing machine used in the air-conditioning warehouse: carbon-dividing molecular sieve physical adsorption and hollow fiber membrane separation, both using air as raw material. The former utilizes different molecular adsorption rates of oxygen and nitrogen molecules in the carbon molecular sieves of the two towers, absorbs oxygen under reduced pressure, decompresses oxygen through continuous decompression, and continuously converts nitrogen into nitrogen in the two towers. The latter is made of polymer materials. The hollow fiber membrane has a series of advantages such as simple structure, easy operation, fast nitrogen production speed, no wearing parts, small size, light weight, low noise, etc. It is a novel and efficient nitrogen production equipment. The common hollow fiber membrane nitrogen generator consists of three parts: an air compressor, an air tank, and a membrane nitrogen generator. The core component of the nitrogen generator is the hollow fiber membrane group. It consists of tens of thousands or even hundreds of thousands of hollow fibers with a diameter of 50-500 μm and is bundled into bundles. The two ends are impregnated with epoxy resin to form a membrane filter and placed in a shell. When the compressed air passes through the hollow fiber, the oxygen and water vapor pass through the membrane at a high rate, and the oxygen-enriched air is released into the atmosphere. Most of the nitrogen gas remains in the membrane due to the slow rate of permeation through the membrane, resulting in higher purity. The product gas, the purity can be adjusted using the purity control valve, the higher the purity, the smaller the flow. Air compressor air supply pressure is generally 1.0 ~ 1.2Mpa, oil content is less than 3PPm. The nitrogen generator itself has a three-stage filtration system. The filtered compressed air requires oil content of less than 0.01 ppm and dust particles of less than 0.01 μm. A large number of nitrogen generators for an air-conditioned storage tank must first be considered to meet the oxygen reduction requirement of the largest air-conditioning in the library, that is, after the fruit is put into storage, the air-conditioning parameter requirements are reached within 1 to 3 days. To take into account the total number of libraries and the total capacity. The main technical parameters of the CA series hollow fiber membrane generator made by Tianjin Senluo are shown in Table 1.

At present, the nitrogen-making machine generally adopts an open substitution (dilution) method to fill the nitrogen between the atmospheres, and 95% to 97% of the purity nitrogen is injected from the upper air inlet between the atmospheres, and the replaced gas comes from the intake air. The exhaust ports arranged diagonally on the mouth are discharged into the atmosphere. The whole process is a dynamic process of constant dilution, and the oxygen content in the reservoir falls down to natural logarithms until it reaches the specified target.

Red jujuba is a one of the most popular ealth tonic and traditional herb in China,Red jujuba are soft on the outside with a sweet smell and moist inside.which has been for thousands of years, by a Chinese Herbal Medicine book "The Classic" saide that, Ziziphus jujubais sweet and warm, spleen and stomach are good for nourishing blood and soothe the nerves.Our Modern production dried dates, water content from about 70% down to about 15%, this export Dried Red Dates are divided into with seeds and without seeds.
Red jujuba may not have a large amount of any one nutrient,Ziziphus jujuba contain a wide array of different ones, including magnesium, potassium, copper, niacin, calcium, manganese, phosphorus, and iron. They contain 20 times more vitamin C than any citrus fruit, strengthening the immune system and fighting infections, which may be why they've been used medicinally for millennia in many cultures.Medical studies have found that Ziziphus jujuba and extracts have the capacity help lower blood pressure, reverse liver disease, treat anemia, and inhibit the growth of tumor cells that can lead to leukemia. Jujube extracts are also used in skin care products used to diminish wrinkles, relieve dry skin, and treat sunburn pain.
