8 Common Mistakes which affect Performance of Milk Cooling Tank!

  1. Choose the right capacity of the milk cooling tank. If you overload the tank it will definitely increase cooling time and power consumption then it will be a concern if the milk-collecting vehicle does not arrive on time. similarly, in case of a small amount of milk, it may cause Icing and delay in cooling as well.
  2. The room temperature should not fall below 5°C or exceed 30°C, depending on climatic conditions. In addition to this temperature range, the cooling unit is operated under appropriate conditions without the intake of an excessive amount of energy.
  3. It is recommended that special air intake is installed. The inlet should be placed in the wall in front of the condenser. The vent should be provided with a movable shutter. Warm air coming from the unit should be removed from the room. To do this, install the outlet of hot air, as high as possible and away from the air inlet. The inlet should be fully open during the summer heat; Intake should be reduced by 90-95% when the outside temperature falls below 5°C.
  1. To ensure a free flow of air, distance from the cooling unit to the wall should not be less than 30 cm.
  2. The tank spread should be about 1/4 to 1/3 of the floor area of the room.
  3. The cooling tank should have a separate power outlet with fuse matched to the power of compressor with overload protection, current circuit breaker and phase change protection at least.
  4. For the prevention of the dry milk residues on the wall of the tank, it must be wash as quick as possible . Then, Cleaning after emptying milk is much easier and more effective. Do not use a hard brush made of metal or other abrasive materials. Also remember to wash the outer surface of the tank. Products used for washing the tank will be remove effectively. Remove Milk residues from the surface of the tank. rather than to destroy the surface of the tank.
  5. You must clean the surface of the condenser once in a month with the help of a dry nylon brush. As a result, the condenser increase productivity, cooling time and reduce energy consumption.
