Description of functions of a washer for a milking parlour

Milk pump controller During milking or cleaning, milk/water in the end unit is pumped out due to a signal from a level sensor and control of the milk pump.
Control of milking and cleaning operation Selection of operation mode: milking (with operation of a milk pump, and optionally with vacuum measurements, milk metering) or cleaning.
Programme selection Selection of a programme depending on a milking parlour size and type.
Adding hot water During main cleaning cycle, an additional amount of hot water is supplied to increase a temperature of water and reduce amount of water used for rinsing.
Manual adding of liquids before cleaning starts A container for liquid added manually, emptied automatically when necessary during the cleaning cycle.
Liquid pumps Automatic dosing of cleaning agents. The amount of agents is automatically adjusted to water and ambient temperatures.
Turbo Power cleaning support To ensure turbulent water flow through a pipe to improve cleaning effectiveness, for a short time an air valve adds a large quantity of air. This results in an effect of a wave raising the cleaning agent and increasing cleaning pressure, and in consequence, the highest effectiveness.
Integrated water tank A container for cleaning liquid from which the liquid is dispensed when necessary during the cleaning cycle.
Water heaters Heaters installed in the water tank to heat cooled water during cleaning or heating water when its temperature is too low. The washer has two sensors monitoring the temperature at different locations in the system.
Water temperature measurements The temperature is measured to switch the heaters on and to stop the circulation, whenever necessary, to heat the liquid. Cleaning starts when the temperature of liquid in the tank reaches its optimum level. This parameter is programmable and can be stored in the memory; it is used to monitor the system operation and parameters of supplied water.
Air temperature measurements A measurement to correct initial water temperature (when the ambient temperature is lower, the water temperature must be higher).
E.g., the water temperature set at 55 degrees C corresponds to the ambient temperature of 20 degrees C; this value is adjusted by 2 degrees C for each 5 degrees C versus the ambient temperature. E.g. Ta - 15 deg C corresponds to Tw - 57 deg C; Ta - 0 deg C corresponds to Tw-63 deg C; Ta-30 deg C corresponds to Tw-51 deg C
A drop in the ambient temperature below 3 degrees C starts an alarm to protect against freezing.
Memory for cleaning parameters, up to 100 cleanings back The washer saves the time of individual cycles, a time of switching the heaters, an hour at which cleaning was started, the water temperature during cleaning and the air temperature. The vacuum value and the amount of obtained milk when sensors are installed.
Bluetooth or WiFi communication, LAN An option for maintenance and programming using Bluetooth, read out of history, or software update.
Vacuum sensor The cleaning effectiveness depends on the vacuum value. When the limit value is reached, the alarm switches on informing about failure (e.g., low pump effectiveness, leak in the system, etc.). During milking the indicator informs about the correct function of the vacuum controller and the pump output. When values of <53 MPa and >38 MPa are reached, the alarm switches on.
SMS module for reporting of operations The washer can send SMSes about failures, e.g., no water, no vacuum, milk pump failure, water temperature not reached, information about a correctly completed cleaning cycle.
Milk metering An additional sensor can measure the total amount of milk obtained, with history of each milking reaching 3 months back.
Programming of operation parameters settings Most parameters of washer operation can be adapted to the existing system and user preferences.
Reminder panel The washer can remind about the expired date for the system maintenance, need to replace fluids or about a withdrawal period when an antibiotic was administered. The information appears before milking is switched on and requires user’s acceptance to start milking or cleaning.
Communication with a mobile device * In preparation. For online readout of operating parameters, reporting of possible errors. Adding information to the reminder panel, e.g., cows covered by the withdrawal period, vet visit, system maintenance, etc.
Cleaning time programming Washer should be started immediately after milking, and it starts a program for rinsing with warm water and waits until a specified time to subsequent cycles. A delay in the main cleaning allows to heat water additionally in the heat exchanger by milk cooled after milking or, e.g., cleaning with hot water at periods of lower energy prices.
Identification of cleaning liquid drawing * In preparation. A sensor measuring conductivity of the cleaning solution informs about correct dosing of acid and alkali during cleaning.


Reminder panel, e.g., cows in the withdrawal period.
Memory with cleaning parameters helps to verify past events
Alarms informing about incorrect system operation
Monitoring of the ambient temperature prevents freezing of water
Monitoring of the vacuum pump operation
Measuring of the minimum temperature at different points with an option to adjust the time of heater operation or the initial temperature according to the cleaning cycle


Monitoring of the vacuum pump operation
Reminder panel, e.g., cows in the withdrawal period
Water temperature at different points, vacuum in the system, quantity of milk obtained
Working time, heater operation time
Memory with last 100 cleaning cycles


Turbo Power system
Programming of a time for starting the main cleaning cycle – the highest temperature of water from the heat exchanges improves effectiveness and reduces energy consumption by heaters
Monitoring of the vacuum pump effectiveness
Adjusting cleaning parameters to a specific system, the ambient temperature, and recommendations of a manufacturer of cleaning liquids
A water tank with additional water heating during the main cleaning cycle and adding hot water during the cycle


Smart adjustment of heater operation and amount of liquid drawn to ambient conditions and operation history (the lowest temperature noted in the working cycle and operating time below the threshold temperature for chemicals effectiveness)
The Turbo Power system increasing effectiveness of cleaning and limiting amount of water consumed
A delay in the main cleaning cycle until the highest temperature is reached in the heat exchanger in the milk cooling process or at periods of lower energy prices
Entering settings for amounts of liquid and water temperature, depending on recommendations of a manufacturer of cleaning liquids
Alarms and monitoring of the ambient temperature preventing freezing of the system, monitoring of the vacuum pump operation limiting consequences of failures, and of cows health
Measuring of amount of milk obtained to monitor quantities of milk sold
