Used as additive in food field, CMC has the functions of thickening, suspending, emulsifying, stabilizing, shaping, filming, bulking, anti-corrosion, retaining freshness, acid-resisting, health protecting, etc. It can replace the application of guar gum, gelatin, agar, sodium alginate, and pectin. It is widely used in modern food industry, such as frozen food, solid drink, fruit juice, jam, lactic acid drinks, condiment, biscuit, instant noodles, bakery products, meat products, etc.
Our food grade CMC has good thickening property, water retention, dispersion stability, filming and chemical stability. It has high viscosity even in low concentration, and makes the food taste delicate and smooth; it can reduce the syneresis of food and extend the shelf life; it can control the crystal size in frozen food and prevent the stratification between oil and water; In acid system, our anti-acid products have good suspending stability, so it can improve the stability of milk and the impedance ability of protein; our CMC can be used together with other stabilizers and emulsifiers to complement each other, strengthen each other`s effect and reduce the cost.

1. Compared with SK water vacuum pump ,It gets high vacuum and pumping speed etc..
2. Simple structure and easy maintenance.
3. The mostly working medium is water and low maintenance costs.
4.The pump is widely use in many areas and suction water vapor,flammable, explosive and various gases contain a small amount of dust and liquid.
5. The pump can works in the harsh condition
1. Series SK,2SK Water Ring Vacuum Pumps can be used to exhaust ordinary gases as well as condensable gases(such as water vapor). Because they have the features of isothermal compression, they can exhaust flammable and explosive gases. When the pump made up of anti-corrosion material is selected, it can be used for exhausting corrosive gases too.
Â
2. Series 2YK Liquid Ring Vacuum Pumps have the features of higher vacuum and better applicability. The different types of gases can be pumped with the selected suitable working media. Therefore, they can be applied in wider range.
Â
3. The pumps run smoothly with low noise and consumption. The energy-saving is 30 percent comparing with the Water Jet and the Water Vapor Jet Pumps.
   If the water is selected as the working medium, the best temperature of supply water should be lower than or equal to 15 °C; the highest one should not be higher than 40°C. While the transformer oil or other low viscosity and saturated vapor pressure industrial oils are as the working media, the general supply temperature should not higher than 40°C and the working media temperature inside the pump chamber should not be higher than 60C, when the liquid with lower boiling point is selected as the working media under some special circumstances, the cooling unit must be equipped to cool down the working media in order to ensure that the max temperature is 30ºC-50ºC, lower than the boiling point. For the closed circulated system of working media, the liquid storage unit and cooler must be equipped, and the gas-liquid separator must be installed at outlet. The mechanical seal should be used for dynamic seal of the shaft.
(1) For the non anti-corrosion pump, the shaft is made of 45#steel or 40Cr, other parts are made of cast Iron or brass;
(2) For the anti-corrosion pump,the parts that the gas passed, should be made of stainless steel 304 and 306, or other material suitable for the respectively corrosive gas, or the parts should be put with anti-corrosion coating.
If the pump is used for vacuuming while transferring gas, the pressure of pump outlet exceeds the standard atmosphere pressure.
When the outlet pressure exceeds 0.15MPa, the special double-stages liquid ring compressor should be chosen and not the vacuum pump refitted. Tthe power of the equipped motor should be increased obviously. And the special gas-liquid separator and auto-drain unit should be equipped too.
When the outlet pressure is below 0.15MPa, it can use the vacuum pump refitted as compressor. The power of the equipped motor should be increased properly.
