果汁Deaerator

Juice Deaerator Improve your product quality with the Vacuum Deaerator Oxygen is vital for life on earth, fuelling processes in daily life such as metabolism of food. It is a requirement for the existence of mankind. However reactions with oxygen also cause degradation. One of these reactions which should be avoided is the degradation of vitamin C. 1mg of oxygen reacts with 11mg vitamin C. If the dissolved oxygen in water is 9 mg/l.1l of water will destroy 99 mg of vitamin C! Another negative effect is the oxidation of both orange and apple juices, giving a brown colour. For juice the normal acceptable O2 content is 0.5-1.0mg/l. XINHAO Vacuum deaerator is intended for product deaeration. During product processing there are many possibilities of entraining air during such actions as pumping, mixing and tank filling. The operating principle of the XINHAO Vacuum is vacuum stripping. The adjustable product inlet is specially designed to ensure a thin falling film in a conical or parasol shape. This gives a large surface area and maximizes the deaeration efficiency. The standard capacity range spans 500-35,000 l/h. The VFJ Product Deaerator-add Value When you install an XINHAO VFJ Deaerator in your process line, you add value to your products and production. Product uniformity Residual O2 levels below 0.5-1.0 mg/l depending on product. Economical production Low maintenance and energy costs. Flexible Production Variable capacity and high turndown to 50% of nominal capacity. Easy implementation of options due to modular design. Compact design minimizes space requirements and pipe runs. The XINHAO Vacuum is skid mounted, which allows easy relocation in the event of production restructuring. Proven Security Every unit leaving the XINHAO workshop is fully tested. Proven functionality and reduced commissioning time. Easy CIP. Ranges of Applications All types of juice concentrate with fibers of up to 12mm long All types of soft drinks, Milk. Sugar syrup. Henry’s Law •Stating the pressure-concentration ratio as an equation and use of the usual modern symbol for the Henry's law constant on a concentration basis gives the following form of Henry's law: •p = k'cc •In this form p is the partial pressure of the gas, c is its molar concentration, and k'c is the Henry's law constant on the molar concentration scale. Henry's law is found to be an accurate description of the behaviour of gases dissolving in liquids when concentrations and partial pressures are reasonably low. O2Levels in Beer & Water •Water about 10 ppm •Beer about 0.1 to 0.3 ppm •Deaerated Water –Cold System •Guarantee <0.03 ppm at >=25 degC •Achieved 0.004 ppm –Hot System •Guarantee <0.02 ppm •Achieved 0.01 ppm Functional Description The product is sprayed as a thin film into the vacuum vessel producing a large surface area. The vacuum reduces the boiling point of the beverage to give quick and efficient oxygen removal. The inlet is adjustable allowing the conical parasolfilm to be optimized for deaeration efficiency. The outlet is equipped with a special level control to avoid the accumulation of fibre. At high temperatures volatile aroma compounds may be lost. This can be avoided by equipping the VFJ with an aroma recovery unit with a recovery rate of up to 99.6%. After cooling and condensing, the aroma compounds are re-introduced into the product giving a result that is almost identical to the original. Products, which foam easily or have a high air content, can cause foaming on entry to the vacuum tank. This foam can accumulate and eventually prevent effective deaeration. This can be avoided by equipping the VFJ with a de-foaming module. Control of the VFJ is normally integrated with the main process line.
