UNDERSTANDING - 8 - CLEANING_Cleaning System Control

Question Title

1. Enter your first and last name

Question Title

2. What part of the milking machine cleaning circuit relies on flooded flow for the most effective cleaning control?

the bulk tank

the water-draw pipe network and jetters that make up the wash manifold

the milk line

Question Title

3. Select all options that match the components with their respective cleaning strategies.

milking units: are either flooded, or alternately flooded and emptied if they are air injected

large components such as some milk meters and recorder jars: are generally cleaned with a spray or sheet of water over the interior surfaces

large components such as some milk meters and recorder jars: require water flow of approximately 3 L/min for effective cleaning

Question Title

4. Select all of the correct descriptions of the role of the milk pump in the cleaning process.

Adding a plate cooler to the milk transfer line will not affect milk pump capacity.

The water flow rate to milking units should be higher in the beginning of each cleaning cycle and lower at the end, to match the capacity of the milk pump.

Milk pump capacity may be a limiting factor in CIP systems.

Unlevel flow distribution between milking units generally requires greater milk pump capacity.

Question Title

5. Drainage is an important aspect of cleaning because:

cleaning solutions need to be drained to prevent mastitis organisms from remaining in the liners

poor drainage increases the milk pump capacity required for cleaning

standing water in the system increases the risk of bacterial growth between milkings and the mixing of different cleaning chemicals during cleaning

Question Title

6. Select all that apply. Assuring adequate flow distribution and mechanical cleaning action:

depends on the skill of the equipment installer

requires testing and adjustment of the water flow to each milking unit and milk meter

typically requires very little added cost to the milking machine

requires precise control of air injection

adds substantial cost to an installation

requires no special adjustment or testing

Question Title

7. Select all that apply. Staff responsible for implementing the cleaning process should be trained in clearly defined operating procedures for milking machine sanitation including:

how to test and adjust the water flow to each milking unit and milk meter, and precisely how to control air injection

the procedures for cleaning the external surfaces of the milking machine, milking parlor, and milk room

the operation of any manually controlled valves, pipes, and switches, and chemical handling including checks for empty chemical containers

how to prepare the milking machine for cleaning and sanitation

how to adjust the system vacuum levels and pulsation rate and ratio

Question Title

8. Select the best answer. Manual cleaning:

is required for some components of milking machines

is required for teatcup liners after each milking

is required for the interior surfaces of bulk tanks

is never required for any components of milking machines

Question Title

9. Select all that apply. An air injector:

on/off timing is relatively unimportant to the success of cleaning

should have the same cycle time as the pulsation system

can be added to the wash manifold to increase the mechanical action of cleaning milk meters, but it is more difficult to control

can be mounted directly to the milk line, or on a wash water draw/delivery line

is a valve that opens to admit air and move cleaning solutions around milk lines

Question Title

10. Select all that apply. What are effective strategies to achieve good cleaning results?

install pipelines, hoses, and components so that they drain by gravity between cleaning cycles

adjust the water flow to avoid big variations in flow between milking units

maximize water flow through the milking units near the receiver

reduce flow to some milk meters if the milking machine floods during cleaning
