Double-effect Falling Film Evaportor Moisture evaporation amount (L/h): 1200 1500 2400 3000 4000 5000 Scope of application: Single effect or multi-effect falling film evaporators are widely applied in foodstuff industry, chemical industry, pharmaceutical industry, biological engineering, environmental engineering, liquid waste treatment etc. They can be applied to the low-temperature continuous evaporation and concentration of such materials as milk, glucose, starch, wood sugar and so on, with the main characteristics of high heat transfer efficiency, short time of materials being heated, which makes them suitable for evaporating materials with hot sensitivity, viscosity, foaminess, etc. Parts of the whole system: evaporators of various stages, separators of various stages, condenser, hot pressure pump, sterilizer, heat preservation tubes, vacuum and drainage system, materials¡¯ transfer pumps of various stages, condensate water pump, branch cylinder, operation platform, electric meter control cabinet, valves, pipes, etc. Main features: 1. The whole heating system of a falling film evaporator is heated evenly by steam and feed liquid is evaporated in the shape of flowing liquid film. So the falling film evaporator has the main characteristics of high heat transfer efficiency and short time of feed liquid being heated, etc. If ever equipped with spray type hot pressure pump, the falling film evaporator will has further virtues of energy saving, low consumption of steam, low volume of cooling water circulation, etc. 2. Water in feed fluid is evaporated when feed fluid flows downwards with accelerating speed and more pressure, which makes falling film evaporators suitable for the evaporation and concentration of feed fluid with rather high viscosity. 3. Feed fluid is evaporated in the shape of film in each pipe and the time of feed fluid being heated is very short, which makes falling film evaporators especially suitable for the evaporation and concentration of foodstuff and makes the preservation of most nutritional composition in foodstuff possible. 4. The process of evaporation is carried out under vacuum, which guarantees the sanitary and environmental requirements of feed liquid and remarkably reduces the evaporating temperature. Moreover, part of secondary steam is inhaled back into the first shell by way of spray type hot pressure pump to mingle with live steam, which saves a lot of live steam. At the same time, steam from hot pressure pump enters heating shell in the shape of spray and spreads swiftly, which makes feed liquid heated mildly. Therefore, falling film evaporators are suitable for the concentration of heat-sensitive raw materials. 5. The equipments are suitable for the evaporation and concentration of foaming raw materials. As feed liquid is evaporated in the shape of film, steam and liquid are already separated in heating pipes. At the same time most feed liquid is pumped out at the bottom of the shell. Only a little feed liquid with all secondary steam come into the separator to be forcefully separated. Feed liquid has not formed tremendous impact. So the formation of foams is avoided. 6. With regard to the concentration and evaporation of foodstuff, the equipments also have the function of killing germs. Law materials are preheated in advance, and then come into a sterilizer with the temperature of more than 94. After being kept in the sterilizer for 24 seconds, law materials come into the first shell and the flash evaporation occurs instantaneously and the temperature drops instantly. 7. The equipments are equipped with CIP cleaning system, realizing in-place clearing. The complete set of equipments is easy to operate, without dead corner. 8. They are ideal equipments for continuous feeding and discharging 9. They are equipped with automatic system, realizing the autocontrol of inlet amount, heating temperature, the concentration of discharging and cleaning. They can also be equipped with safeguard of sensitive law materials against sudden power failure, malfunctions and other automatic operating and control systems of safety and alarm. Wooden case.
Working principle of the oil heater The user only needs to connect the equipment to a power supply, and arrange medium inlet and outlet pipes and electrical interfaces before use. Electrical heat conduction oil furnace (also known as oil transfer heater), the electric heater is directly inserted into the organic carrier (heat transfer oil) for direct heating. A circulating pump is used to create liquid-phase circulation of heat conduction oil, thus, to transfer the heat to one or several pieces of heat using equipment. After unloaded in the heat using equipment, heat transfer oil will return to the heater via the circulating pump, again to absorb heat, and transfer the heat to the heat using equipment. This process is repeated again and again, realizing continuous transfer of heat. As a result, the temperature of objects being heated rises, and heating requirements are fulfilled. The oil heat transfer machine adopts a digital display temperature controller, and has functions of over temperature alarm, low oil level alarm and over pressure alarm. Characteristics of oil heater 1)our electric heat conduction oil furnace is equipped with a perfect operating control and safet monitoring device, so it can realize automation control 2)it can reach a higher operating temperature under lower operating pressure 3)high thermal efficiency, can reach to higher than 95%, the control precision can be 4)the equipment is of small volume, flexibility to install, adapting to install nearby the heat using equipment
