Molasses high viscosity gear pump

Molasses is a thick, dark brown, semi-fluid substance, mainly containing sucrose. The content of pantotic acid in sucrose is relatively high, up to 37mg/kg. In addition, the content of biotin is also considerable, which is easy to be mixed into soybean molasses and molasses fermentation broth. Molasses [1] is the by-product of the sugar industry, composed of sugar for raw materials, processing conditions and there are differences, which mainly contains a lot of fermentable sugars (mainly the sucrose), so it is very good fermentation raw materials, can be used as yeast, monosodium glutamate, organic acid fermentation products such as substrate or makings, can be used as a certain food ingredients and animal feed. Sugar beet molasses, sugar cane molasses, grape molasses, corn molasses, and transformed molasses and refined molasses are the major molasses producers. A by-product of the sugar industry. In the process of sugar making, the brown viscous liquid remains after the crystallization of sugar. Belongs to energy feed, because of sweet taste, used as seasoning. According to the raw materials of sugar can be divided into sugar cane molasses, beet molasses and starch molasses. The nutrients of molasses vary. The general sugar cane molasses and beet molasses were expressed as converted sugar, and the total sugar content was 48.0% and 49.0%, respectively. Water content: 25.0%, 23.0%; Crude protein 3.0% and 6.5%. Starch molasses is a by-product of glucose production after enzymatic hydrolysis of cereal starch. The total sugar content is more than 50.0%, the water content is 27.0%, and the crude protein content is very small. [2] Nutritional properties Molasses containing a small amount of crude protein, 3% ~ 6%, much as part of the nonprotein nitrogen, such as ammonia, amide and nitrates, which accounts for only 38% ~ 50%, nitrogen amino acid and non-essential amino acids such as aspartic acid, glutamic acid content is more, so the protein biological value is low, but aspartic and glutamic acid are a flavor amino acids, it can greatly stimulate the animal used for animal feed in the appetite. The main component of molasses is sugar. Sugarcane molasses contains about 24%~36% sucrose and other sugars about 12%~24% sucrose. Almost all sugar in beet molasses is sucrose, about 47%. In addition, it contains 3%~4% soluble colloid, mainly xylose, Arabic gum and pectin. The mineral content of molasses is high, about 8%~10%, but the content of calcium and phosphorus is not high, sugarRead More…

The medium to be transported and its temperature should be within the allowable range of the pump material. 5 for the delivery of liquid is easy to precipitate crystallization of the medium, after use should be cleaned in time to remove the electric diaphragm pump, so as not to open the damage.


Haina sewage pump develops new trends in the industry

Focusing on environmental protection and energy saving, haina sewage pump develops new trends in the industry. As we all know, the fourth industrial revolution is gaining momentum around the world, leading human society to a new development trend. And our country becomes the main participant of this revolution and promoter. However, while promoting the rapid economic development through industrial reform and adjustment, it also causes the continuous deterioration of the ecological environment, which becomes a serious obstacle to the further economic development, and water pollution is a significant sign. In order to solve water pollution, the Chinese government has formulated an ecology-friendly development strategy and actively constructed a system of harmonious development between man and nature. Haina is an example of striving to implement the national environmental protection strategy and constantly promoting its own development through scientific and technological innovation. In 2001, a future industry famous brand was born in Hebei beach, this is haina pump industry manufacturing co., LTD. Through 20 years of hard work, haina has been continuously accumulating and quietly moving forward. Now it has developed into a modern large-scale enterprise integrating r&d, production, sales and other functions.

Magnetic pump development

With the rapid development of industry, the problem of environmental pollution should not be ignored. Developed countries have realized that in the past chemical industry development process in the rapid neglect of environmental damage caused by the leakage problem, so with all accidental injury legislation in the early damage in the medium must be no leakage pump to pump, or must bear the additional high environmental costs. The beauty of nature surrounds the leak-free pump to pump of mandatory environmental pollution since 2000. Leak-free pumps will be available in pharmaceutical, chemical and petrochemical plants in Europe and the americas, and almost all media will use magnetic pump except water. In addition to no leakage, no leakage pump, maintenance free, long life, and many other advantages. The same is true in China, where the government and companies are gradually starting to reflect the initial stage of development and pay a high price, as the product of the economic development has reached a certain stage. In the past two years, with the chlorine gas leakage of the circulating liquid, the toxic chemical medium pollution and the explosion of the chemical plant, causing environmental damage and making people realize the importance of safe production. How to reduce leakage is increasingly an urgent issue for companies to produce, and even for government regulation and legislation to consider. There are two kinds of leakage-free pump technology, one is the shield pump to Japan represented; The other is the magnetic pump represented in Europe and the United States, a branch of nansheng company, was invented in 1946 in the United Kingdom HMD. Despite the advantages of easy maintenance and simple operation of magnetic pumps relative to shielded pumps, shielded pumps were introduced long before magnetic pumps were enclosed in the market. And magnetic pump quality, performance and application capacity has not been due to the affirmation, the reasons are various. Some enterprise product design and manufacturing quality control is not enough, training the customer’s application and service concern is enough one of the main reasons. In fact, magnetic pumps are widely used, especially for flammable, explosive, highly toxic, high power, high temperature, high pressure, strong corrosion of the harsh liquid transport process. Therefore, the development of the market is dominated by the increasingly updated user concept and the constantly innovative technology of the magnetic pump itself. The major manufacturers in the Chinese market focus on productRead More…


Stainless steel gear pump application

1. For cooking oil, olive oil, vegetable oil, animal oil, essential oil, glycerin, sesame oil and other liquids, please choose stainless steel gear pump when conveying. Stainless steel gear inside the piston pump: the gear has high temperature resistance and long service life. Mechanical seal: corrosion resistance, no leakage, etc. Stainless steel plate: wear resistant, corrosion resistant, long service life. These configurations make the pump resistant to corrosion and do not contaminate the liquid when it is transported. 2. For beverage, fruit orange, vinegar, alkali, yogurt, grain oil, soy sauce and other liquids, zyb slag oil pump should be selected when transporting When the particles pass the gear, Being crushed will not cause damage to the gears. A pair of gears in the pump body divides the internal space into two parts. When the gears rotate to draw in the area, negative pressure is generated. Draw the liquid into the pump from the inlet to the outlet, forming a high pressure to discharge the liquid out of the pump body. So this pump can work continuously for a long time. 3. Honey, sesame paste, bean paste, syrup, pear paste, royal jelly and so on. NYP type high viscosity gear pump should be selected when conveying. NYP high viscosity gear pump pump in the pump body of the gear and meniscus closely occupy each side of the rotor, When the gear rotates, it will drive the rotor in the same direction. The gear has no wear, no pulsation and no noise. This pump has a transmission viscosity of up to 300,000 CST, smooth operation, wear-resistant, corrosion-resistant and long service life. Which gear pump to choose for food depends on the viscosity, flow, pressure, temperature and other characteristics of the liquid.
