This invention is related to the type of washing system for milking machines with milk bucket used for milk production of small-medium scaled dairy farms.
The invention is related to an automatic washing method which is used for automatically washing the bucket milking machine after milking. It is related to a milking machine with a milk bucket that has an automatic washing system which comprises pre-rinsing, washing, final-rinsing process steps and of detergent dosing unit, washing boiler, milk can, milking cluster(s), washing jetter, washing line, liquid drafting line in the milk can, milk can vacuum connection, washing boiler vacuum connection, boiler-milk can vacuum orientation and vacuum discharge valve, boiler and milk can interim valve, washing line valve, drainage valve, drainage line, water heating resistance, cold water intake valve, hot water intake valve, float bottom level sensor, float upper level sensor. This invention both increases the quality of the milk and prevents giving damage to the udder.
In the previous technic, the milk milked by the machines are collected in to a milk bucket. The milker empties the milk bucket by transferring the milk to another bigger container/bucket at the end of milking and thus the milker prepares the machine for the next animal to be milked. Said milking is very difficult and it is very tiring for the milker.
As it is known, the milking machines must be washed appropriately after each milking process without any delay. Delay in washing, not making a full wash or not making any wash causes proliferation of the bacteria in a very fast manner within the milking equipment. These bacteria cause infection on the udder of the animals at the next milking and also infecting the milk.
Due to the infection of the udders, besides the bacteria contaminating the milk via the milking equipment, the somatic cell in the milked milk also increases, increased somatic cell affects the milk production in a negative manner and the raw milk quality is impaired. As a result of the impaired milk quality, the milk is processed with extended duration and/or at high temperatures during pastorization, therefore energy consumption increases. The pH level of milk with high bacteria load increases, thus it substantially decreases the yield of milk products, excellence and product quality in the production of dairy products such as yoghurt, cheese etc.
The producers usually avoid washing the bucket milking machine or perform an insufficient washing because it requires an intensive labor. As a result of this, the udder diseases increase (Mastitis), the quality of the milk cannot reach to the required level. The raw milk quality targets specified in the declaration No 2000/6 of the Ministry of Agriculture (Number of total bacteria<100.000 number/ml, number of somatic cells<400.000 number/ml) can not be reached yet due to the fact that the milking systems of small-medium scaled enterprises are not washed properly, in contrast the current numbers of total bacteria and somatic cells are very far away from the targeted values as of the year 2018 in Turkiye and in many other developing countries.
As a result, due to insufficiency of the current solutions for solving the abovementioned problems within the current technics, it is necessary to make a development in the relevant technical field for a new washing system and equipment.
The present invention solves all of the abovementioned problems at the same time. Said invention is in general related to a method which provides excellent automatic washing of all surfaces that contact with the milk in the bucket milking machine.
The most important aim of the present invention is to increase the milk production and raw milk quality by decreasing the somatic cells besides the bacteria contamination to the milk by the milking equipment by means of preventing the udders to be infected due to dirty milking equipment.
Another aim of the present invention is to provide appropriate washing of the milking machine in a standard and sufficient manner by bringing an easy solution to the milker who refrain from washing the milking machine because it eliminates the washing labor of the milker.
Another aim of the present invention is to enable washing of the milking machines appropriately without any delay after each milking process, due to its ease of use.
The most important aim of the present invention is to protect the health of other animals in the herd by means of preventing the infection of the udders.
Another aim of the present invention is to reduce the energy consumption by providing treatment of the milk within a shorter period of time and/or at low temperature during process at milk factories.
Another aim of the present invention is both to perform standard milking process by means of reducing the initiative of the milker on the milking machine and to improve the working conditions.

The present invention will be understood more clearly with the abovementioned reference numbers and description referring to the attached FIGURE.
The present invention is shown in
For pre-rinsing; cold water is taken into the boiler from the cold water intake valve (20); when the water amount taken into the boiler (2) reaches to the required level, it cuts water intake by triggering the upper level sensor (24) of the float (22), operates the vacuum pump (11). At this phase vacuum orientation valve (13) while transferring the vacuum to the milk bucket, interim valve between boiler-milk bucket (14) is in a closed position, washing line valve (15) is open; drainage valve (16) is closed. The vacuum pump (11) takes the rinsing water within the boiler (2) into the milk bucket (3) by passing through the washing jetter (5) and milking cluster (4). During this stage together with the reduction of the water in the boiler, the float of the boiler (22) triggers the lower level sensor (23); the washing line valve (15) is closed, the boiler and milk bucket interim valve (14) is opened. Together with the opening of this valve, to the vacuumed environment within the milk bucket (3), a sudden atmospheric air inlet is provided by means of the inter milk bucket liquid drafting pipe (7) up to the bottom point of the milk bucket and after the water within the milk bucket (3) is provided to all points in the milk bucket in a pressurized manner thus rinsing is provided. After this process the boiler-milk bucket vacuum orientation valve (13) directs the vacuum to the washing boiler vacuum connection (12); it allows the atmospheric air way to the milk bucket vacuum connection (10). Due to the increased vacuum within the boiler (2), the dirty rinsing water within the milk bucket (3) is drafted into the boiler (2) through the inter milk bucket liquid drafting pipe (7) because the boiler-milk bucket interim valve (14) is open. When the whole dirty water is drafted into the boiler (2), the vacuum pump (11) is closed; the dirty rinsing water is drained by mean of opening the drainage valve (16). Therefore the pre rinsing process is completed.
After the pre-rinsing stage, the system passes to the washing stage with the solution consisting of the hot water and detergent. At this stage detergent dosing unit (1) gives a sufficient amount of detergent into the boiler (2). If there is any external hot water source in the enterprise, hot water is taken into the boiler (2) by means of the hot water valve (20.1); if there is no hot water source then water is taken from the cold water valve (20) and the heating resistance (18) starts to work until the washing solution is heated to the predetermined temperature. Water intake into the boiler (2) stops when the water level in the boiler (2) triggers the upper level sensor (24) of the float (22); the system waits for reaching the solution temperature up to the required level. The water within the boiler (2) is brought to the required temperature by means of the resistance (18) and is brought to the required level, then the float upper level sensor (24) is triggered and the vacuum pump (11) is operated. At this stage the vacuum orientation valve (13) transfers the vacuum into the milk bucket (3), the boiler-milk bucket interim valve (14) is closed, the washing line valve (15) is opened, and the drainage valve (16) is closed. The vacuum pump (11) drafts the solution within the boiler (2) into the milk bucket (3) through the washing jetter (5) and milking cluster (4). In this case, the solution amount within the boiler (2) is reduced and the lower level sensor (23) of the float (22) is triggered, then the washing line valve (15) is in a closed position, the boiler-milk bucket interim valve (14) is in an opened position. When the boiler-milk bucket interim valve (14) opens, the vacuum in the milk bucket (3) provides sudden atmospheric air inlet to the environment by means of the inter milk bucket liquid drafting pipe (7) which reaches to the lowermost point of the milk bucket, then the washing process of the system is provided by reaching with the solution in the milk bucket (3) to all points within the milk bucket (3) in a pressurized manner. After this process the boiler-milk bucket vacuum orientation valve (13) directs the vacuum to the washing boiler vacuum connection (12); it allows the atmospheric air way to the milk bucket vacuum connection (10). Due to the increased vacuum within the boiler (2), the solution within the milk bucket (3) is drafted into the boiler (2) through the inter milk bucket liquid drafting pipe (7) because the boiler-milk bucket interim valve (14) is open. When the whole solution is drafted into the boiler (2), the vacuum orientation valve (13) transfers the vacuum into the milk bucket (3), the boiler-milk bucket interim valve (14) is in a closed position, the washing line valve (15) is in an opened position, and the drainage valve (16) is in a closed position. The vacuum pump (11) drafts the current solution within the boiler (2) by means of passing through the washing jetter (5) and milking cluster (4) and then redrafts it into the milk bucket (3) by means of the milk hose (9). This process is repeated several times and all surfaces in contact with the milk in the system are washed. After all of the surfaces are washed with the solution and hot water, the solution is drafted into the boiler (2) for the last time, then the vacuum pump (11) is closed, the drainage valve (16) is opened and the solution is drained.
The system passes to the final rinsing stage after the washing stage. At the final rinsing stage first of all cold water is taken into the boiler (2) by means of the water valve (20), when the water level which is filled into the boiler (2) reaches the required amount, water intake is stopped by means of triggering the upper level magnetic sensor (24) of the float (24). The control panel (19) actuates the vacuum pump (11). At this stage, the vacuum orientation valve (13) within the system transfers the vacuum to the milk bucket, the boiler-milk bucket interim valve (14) is in a closed position, the washing line valve (15) is in an opened position, and the drainage valve (16) is in a closed position. The vacuum pump (11) drafts the rinsing water within the boiler (2) into the milk bucket (3) through the washing jetter (5) and the milking cluster (4)
Together with the reduction of the water within the boiler (2), the lower level sensor (23) of the float (22) is triggered; it closes the washing line valve (15), opens the boiler-milk bucket interim valve (14). When this valve is opened, to the vacuumed environment in the milk bucket (3), a sudden atmospheric air inlet is provided by means of the inter milk bucket liquid drafting pipe (7) which reaches to the lowermost point of the milk bucket, the final rinsing is provided by means of reaching to all points with the water in the milk bucket (3) in a pressurized manner.
After this process, the boiler-milk bucket vacuum orientation valve (13) directs the vacuum to the washing boiler vacuum connection (12); it allows the atmospheric air way to the milk bucket vacuum connection (10). Due to the increased vacuum within the boiler (2), the dirty rinsing water within the milk bucket (3) is drafted into the boiler (2) through the inter milk bucket liquid drafting pipe (7) because the boiler-milk bucket interim valve (14) is open. When the whole water is drafted into the boiler (2), the vacuum pump (11) is closed; the final rinsing water is drained by means of opening the drainage valve (16).
The boiler-milk bucket interim valve (14), the washing line valve (15) and the drainage valve (16) are valves operated by actuators which open and close the passages. The boiler-milk bucket vacuum orientation and vacuum discharge valve (13) are valves, that closes the free air passage of one side when vacuum is oriented to that side, and at the same time cuts the vacuum feeding of the other side, opens the free air passage of the side whose vacuum is cut previously.
