Not every cow owner can afford the Delaval milking machine due to the high cost. However, the happy owners of the equipment appreciated the true Swedish quality with dignity. The manufacturer produces stationary and mobile milking machines, has deployed a large dealer network on the territory of the Russian Federation.
Advantages and disadvantages of Delaval milking machines
The Delaval apparatus is manufactured by a Swedish company. The manufacturer offers mobile models for private use, as well as professional stationary equipment for large livestock farms. Regardless of the type of model, the work is based on vacuum milking. Advanced devices can be controlled remotely from the remote control.
The only disadvantage of Delaval equipment is its high cost. For example, for a mobile device MU100 you will have to pay at least 75 thousand rubles. However, a good milking machine justifies its cost. The device is of impeccable quality, suitable for milking goats and cows.
All Delaval machines are equipped with the Duovac system, which provides a double vacuum. Automatic milking takes place in an udder-friendly mode. In other words, the animal will not get injured if the milkmaid forgot to turn off the milking machine motor in time. At the end of milking, the system will automatically switch on the gentle mode.
A larger list of all the advantages of Delaval can be viewed on the MU480 model:
- The versatility of the milking system lies in the ability to work with suspension systems designed for small and large milk yields. The operator is given the opportunity to more accurately select the suspension part, suitable for the milk flow for each herd of cows.
- The presence of an intelligent identification control system speeds up the milking process by streamlining repetitive operations. The principle of operation is based on determining the number of a cow whose milking has already been performed.
- The ICAR milk meter allows you to accurately record the milk yield. Additionally, the system takes samples. If necessary, the operator is able to examine the quality of the milk at any time.
- The high cost of the MU480 device is due to the presence of a wireless connection to control the remote milking. The data is sent to a central computer. Once the cow has been identified, the system notifies the operator of preparation for milking. During the process and until it ends, data continues to flow to the computer at high speed. In case of malfunctions, errors, the operator instantly receives a signal.
The big plus of the Delaval apparatus is its stable vacuum. The working pressure is constantly maintained in the harness. Milking is carried out safely, at high speed, until the milk is completely withdrawn.
The lineup
Delaval products are intended for private and professional use on large farms. Conventionally, the models are divided into two large groups: for conventional and remote milking.
The MMU line is designed for conventional milking:
- The milking machine MMU11 is designed for 15 cows. According to the milking speed, a maximum of 8 animals can be served per hour. The Delaval apparatus is equipped with one attachment kit. Only one cow can be connected to the equipment during milking.
- Models MMU12 and MMU22 are in demand by owners of small farms with more than 30 cows. Delaval devices have two sets of attachment systems. Two cows can be connected to one milking unit at once. On a farm, animals are lined up in two rows of two heads. The milking machine is installed on the aisle. Milking is performed first on two cows of the same row, then they move on to the next pair. The convenience of the scheme is explained by the increased milking speed. Only glasses with hoses of the hinged system are thrown onto the other row. The device remains in place. An experienced operator can serve up to 16 cows per hour.
Milk is collected in cans with a capacity of 25 liters. Delaval machines can be connected to a fixed line to transport products directly to the refrigerator. When using cans, containers are placed on a trolley. Transport must be equipped with wide tires for better cross-country ability. Stability during parking is provided by steel legs.
The Delaval suspension system has teat cups. Elastic food-grade rubber inserts are installed inside the body. They are the ones that are put on the teats of the udder of a cow. The glasses are supplied with vacuum and milk hoses. Their second end is connected to the fitting on the manifold cover.
For remote milking, manufacturer Delaval has developed the MU480. The operation of the apparatus is controlled by an electronic unit. The tasks are set by the operator via the remote control. A computer program monitors all milking processes. The unit is capable of operating with more than one harness. The motor can be started from the touch screen or via a computer. The operator only needs to manually place the cups on the teats of the cow's udder.
With the start of milking, milk is sent to a common line. The program remembers each cow by number. The software records the milk yield of an individual animal, calculates the total volume of raw materials received. All data remains in the memory of the central computer. The software sets an individual milking rhythm for each cow and maintains an optimal vacuum level. Sensors recognize the likelihood of mastitis, the onset of an inflammatory process or heat. The software even compiles an optimal diet to maximize milk yield.
During operation, the MU480 frees the operator from tracking the milking. At the end of the flow of milk, a signal is sent to the computer, the glasses are automatically detached from the udder.

Specifications
Delaval MMU oil milking machines are characterized by the presence of a vacuum gauge, a pulsator, and a vacuum regulator. During operation, the system maintains a rhythm of 60 pulses per minute. The work of the vacuum pump is provided by an electric motor. The start is done manually with a button. To protect against overheating, the motor is equipped with a sensor.
The MMU milking units use a 0.75 kW electric motor. The connection is made to a 220 volt single-phase electrical network. Delaval equipment operates stably in a temperature range of - 10 aboutFrom to + 40 aboutC. The apparatus is equipped with an oil-type rotary vacuum pump.
Instructions
The MMU milking cluster starts with the mains connection. By pressing the start button, the engine is started. The engine is left to idle for about 5 minutes before milking. During this time, air is pumped out of the hoses, a vacuum is created in the chambers of the glasses. During idle operation, the operator tests the performance of the units, checks the absence of depressurization of the system, oil leakage, and extraneous sounds.
After adjusting the desired level of vacuum, the teat cups are put on the teats of the cow. At the beginning of milking, the milk flows through the hoses into the container. The Delaval milking machine provides a three-stroke milking mode.Two phases are aimed at compressing and unclamping the nipple, due to which milk is expressed. The third phase provides rest. When milk stops flowing into the hoses, milking ends. The motor is turned off, the teat cups are carefully removed.
Conclusion
The Delaval milking machine will pay off after a couple of years of operation. Reliable Swedish equipment will work for a long time without breakdowns, if you follow the basic rules of operation.
