The material is in the vacuum state when the evaporation equipment is processed, the heating source temperature of the material is low, the evaporation temperature is low, the high temperature steam into the equipment can quickly evaporate, the temperature is generally between 35℃~100℃, the material is uniform, will not produce foam, running material, coking, Therefore, the food industry processing juice, wine, starch, sugar, additives, fermentation and other fields will choose MVR evaporator.
Design and manufacture special evaporator for beverage, seasoning, wine, milk and other customers
Type of concentrated juice evaporator
In the concentrated juice industry, in order to greatly reduce the energy consumption of the juice evaporation process, a juice low-temperature heat pump parallel flow multi-effect evaporation system was innovatively designed, which combined the steam injection heat pump technology with two energy-saving measures of extracting extra steam preheated juice.
The simulation results of a low-temperature heat pump with concurrent flow three-effect evaporation system for concentrated orange juice show that when orange juice is preheated to 70℃, the injection coefficient of the heat pump is set to 0.7, and the exhaust position is set to the second effect, the consumption of raw steam can be saved up to 46%.
The low temperature heat pump co-flow multi-effect evaporation system using the above two energy saving measures is efficient and energy saving under the conditions of heat pump injection coefficient and extraction position, especially suitable for the evaporation of heat sensitive solution such as juice.
Multieffect evaporation is an important unit of operation commonly used for concentrated heat-sensitive solutions (usually aqueous) such as fruit juices, vegetable juices and milk.
Because evaporation process needs to consume a large amount of heated steam (raw steam) to remove most of the water in the solution, so energy saving is an important problem to be solved in evaporation operation.
Under the condition of heat transfer and temperature difference required for evaporation, it is one of the main measures to save energy to increase efficiency as much as possible and make full use of latent heat of vaporization of secondary steam. However, as juice is a heat-sensitive material, it needs to be evaporated at low temperature and low pressure to maintain its nutritional composition and natural flavor.
Because juice is heat-sensitive material, the evaporation temperature of the first effect juice should not be too high, so the increase of efficiency is technically restricted. Two-effect or three-effect is more common.
In order to save energy, we can also use the evaporation energy saving measures of the latent heat of secondary steam vaporization, using steam injection heat pump technology and mechanical compression heat pump technology.
The type of concentrated juice evaporator is customized according to the required characteristics and quantity of concentrated juice solution.
