Forced Circulation Evaporator is a highly useful and advantageous apparatus, which can conduct evaporation with the help of reduced pressure. Three factors are to be considered when designing a forced circulation evaporator: liquid-steam separation, exchange of heat, and energy-efficiency. Hence in these evaporators the flow velocity in the tubes is kept very high. Across the globe, GEA’s plants, processes and components contribute significantly to the reduction of CO2 emissions, plastic use as well as food waste in production. It has medium to large flow rates capacity. We use cookies on our website. Single-effect evaporator Multi-effect evaporator pan evaporator natural-circulation evaporator rising film evaporator falling film evaporator rising-falling evporator forced circulation evaporator. A plate-and-frame configuration employs special plates, with alternate product and heating channels. Since liquid circulation is maintained, the flow velocity in the tubes and the liquid temperature can be controlled to suit the product requirements independently of the pre-selected temperature difference. These gaskets can be inserted and removed without special tools. forced circulation evaporator Circulation evaporators are a type of evaporating unit designed to separate mixtures unable to be evaporated by a conventional evaporating unit. Forced circulation evaporators are used if boiling of the product on the heating surfaces is to be avoided due to the fouling characteristics of the product, or to avoid crystallization. Forced circulation type of evaporators are recommended for the concentration of high viscosities solutions/slurries which have a tendency to crystallize or produce scales. The circulating pump horsepower is higher than rising or falling film units due to increased liquid pumping rates. Direct or indirect condenser, according to the evaporator size. Color, size distribution of salt crystals and energy consumption are surveyed. Our forced circulation evaporator is designed for evaporation of liquids with a high solids content, high viscosity, tendency to foul, and also for crystallizers. Evaporators Single-effect evaporator Multi-effect evaporator pan evaporator natural-circulation evaporator rising film evaporator falling film evaporator rising-falling evporator forced circulation evaporator. Forced Circulation Evaporators A forced circulation evaporator is shown schematically in Figure 6.2. Forced circulation evaporators are tubular heat exchangers for concentrating a feed. forced circulation evaporator manufacturer/supplier, China forced circulation evaporator manufacturer & factory list, find qualified Chinese forced circulation evaporator manufacturers, suppliers, factories, exporters & wholesalers quickly on Made-in-China.com. Features Downloads. Forced Circulation Evaporator for the cobalt / nickel / lithium salt crystallization Application The most common use of this evaporator is as an evaporative crystallizer with materials having relatively flat or inverted solubility. The heated feed stream (see above) is mixed with the large circulating stream, which flows through the main heat exchanger. Forced Circulation Flash Evaporator In the forced circulation flash evaporator, the heat exchanger is mounted horizontally although vertical mounting is possible. Forced Circulation E vaporator (FCE) is a combination of shell and tube heat exchanger, a separator and circulation pump. We are here to help! Forced-Circulation Evaporators During the designing stage of a tubular evaporator, it is essential to assess the value of the mechanical recirculation. Forced Circulation Evaporators. also to make the balance of energy and masses. The product is sent to the exchanger where it is heated and then sent to the separator. TMCI Padovan Forced Circulation Evaporators Corporation Information Table 98. Tubes are generally made of metals with a high thermal conductivity, though scale formation may occur on the tubes which reduce the tube conductance. systems. Circulation pump is axial flow pump with high discharge and low head. Proper design results in controlled temperature rise, controlled temperature difference and tube velocities that give optimum heat transfer. The liquid is recirculated by a centrifugal pump through an external (or internal) heat exchanger at high velocity (3-5 m/s), heated by condensing steam (or water vapors). The Pump maintains good velocity of liquid in tubes. Application Range of Forced Circulation Evaporator The force circulation evaporator is suitable for concentrating products with high levels of solid material content and/or high viscosity like tomato paste, tropical fruit papaya or mango puree , medicine, food deep processing, biochemical engineering, environmental protection engineering, waste liquid recovery and treatment, and chemical industry. It has been used to evaporate components like thermo labile materials. Skills: Chemical Engineering. Upon entering the separator, the pressure in the liquid is rapidly reduced resulting in some of the liquid being flashed, or rapidly boiled off. Forced Circulation Evaporator, Forced Circulation Concentrator, Single Effect Forced Circulation Evaporator manufacturer / supplier in China, offering Double Effect Forced Circulation Vacuum Evaporator Concentrator for Tomato Paste, 2000kg/H Non-Dairy Creamer Production Line Design and Equipment, 1000kg/H Non-Dairy Creamer Production Line Design and Equipment and so on. Horizontal or vertical shell-and-tube heat exchanger or plate heat exchanger as the calandria, with flash vessel/separator arranged above the calandria, circulation pump. The amount of evaporation that takes place depends on the temperature difference between the steam and the solution. Higher liquid velocities and the lack of boiling in the heat exchanger tubes help to prevent the tubes from coating. Forced Circulation Evaporator. Psychrometrics Psychrometric Chart Example1 (Psychrometric Chart) (given dbt, … Liquid to be concentrated is circulated through the tube at high pressure using a pump. Forced Circulation Evaporator, Evaporator, Three Effect Evaporator manufacturer / supplier in China, offering Forced Circulation Evaporator for The Salt Crystallation, Stainless Steel Continuous Evaporator, for Industrial, Automation Grade: Automatic, Zero Liquid Discharge (Multiple Effect Evaporators) and … Forced circulation evaporator. In an evaporator using tubing, after the water begins to boil, bubbles will rise and cause circulation, facilitating the separation of the liquid and the vapor at the top of the heating tubes.
