Crystal 20kg Dairy Circulation Cleaner
Evans Crystal is a concentrated chlorinated alkaline powder for circulation cleaning in dairy milking pipelines and bulk milk tanks. Its caustic formulation contains sodium hydroxide and is designed for the cleaning demands of the milking parlour. This listing supplies the 20kg bucket, manufacturer order code R060JEV, for preparation of a measured working solution.
The free-flowing powder dissolves quickly and works in hard or soft water. Its low-foaming action suits circulation cleaning, while free rinsing helps operators complete the wash cycle. Evans also describes Crystal as defatting and protecting rubbers and helping to prevent milkstone build-up as part of a regular equipment-cleaning programme.
For the specified in-place method, Crystal is dosed at 100g in 40 litres of water, giving a manufacturer-stated yield of 8,000 litres of working solution from a 20kg bucket. The procedure includes hot-water preparation, a minimum return-line temperature and a ten-minute circulation stage. Each step matters when planning a repeatable cleaning routine.
Include Crystal within a documented dairy hygiene programme and follow the instructions for the plant or tank-cleaning equipment. The concentrated powder is corrosive and must be handled without breathing dust. Keep the current label and safety data sheet available, measure carefully and complete the required clean-water rinse before equipment is returned to use.
Key Features & Benefits
- Concentrated cleaning powder: a chlorinated alkaline formulation containing sodium hydroxide for dairy circulation cleaning.
- Quick dissolution: free-flowing powder that dissolves readily when prepared as directed.
- Low foam: suitable for circulation through pipeline milking equipment.
- Hard- or soft-water use: supports cleaning across different water conditions.
- Free-rinsing performance: allows the cleaning solution to be rinsed away during the required final rinse.
- Rubber care and deposit control: described by Evans as defatting and protecting rubbers and helping prevent milkstone build-up.
- Measured working yield: the 20kg bucket provides 8,000 litres of solution at 100g per 40 litres.
Directions for Use
Prepare the plant immediately after milking
Remove dirt from clusters, tubes and jetters. Thoroughly rinse the plant with clean, cold water and run to waste. Read the label, safety data sheet and equipment instructions before handling the concentrate. Wear protective gloves, clothing and eye or face protection, and avoid inhaling dust.
Dissolve the measured powder in water
For in-place cleaning, prepare 100g Crystal in 40 litres of hot water at 82°C while stirring. Add the product carefully into the water. Never add water directly onto the powder: the safety data sheet warns that this can cause a vigorous reaction or boiling. Do not mix Crystal with other chemicals.
Circulate, discharge and rinse
Draw the prepared solution into the plant, allowing some to run to waste until the return line discharges hot solution at a minimum of 50°C. Set the return line for circulation and circulate for ten minutes, then run to waste. Rinse the plant thoroughly with clean, cold water and allow it to drain.
Follow the bulk-tank spray equipment procedure
For automatic or hand-operated bulk-tank spray-cleaning equipment, follow the equipment manufacturer's instructions. Evans specifies inspection at least weekly for tanks with manhole access and advises consulting the automatic cleaning equipment manufacturer if problems arise. Use the site's appropriate inspection procedure; the product sheet does not provide a separate universal tank-spray dose or cycle.

FAQs
What is Crystal used for?
Crystal is used for circulation cleaning of dairy milking pipelines and for compatible bulk milk tank cleaning systems. It is a concentrated chlorinated alkaline powder, with separate guidance for the in-place pipeline method and tank spray equipment. Match the cleaning procedure to the installation and follow the equipment manufacturer's instructions.
What is the standard dose for in-place cleaning?
The manufacturer specifies 100g in 40 litres of water at 82°C, prepared while stirring. Add the powder carefully into the water, then follow the return-temperature and ten-minute circulation procedure. Do not apply this dose automatically to every tank-spray system, as those systems must follow their own equipment instructions.
How much working solution does the bucket make?
A 20kg bucket provides 8,000 litres of working solution at the stated 100g per 40 litres dilution. The number of cleaning cycles depends on how much solution the particular plant requires. Accurate measurement helps staff maintain the correct concentration and estimate usage for their own cleaning programme.
Can Crystal be used in hard water?
Yes. Evans specifies Crystal for both hard and soft water. Prepare it at the stated dose and complete the full cleaning and rinsing procedure, while monitoring results through the site's equipment-care routine. Consult the product or equipment supplier if the installation requires a different approved programme.
Is Crystal low-foaming and does it need rinsing?
Crystal is described as low-foaming and free-rinsing. The in-place method still requires the used solution to run to waste, followed by a thorough clean, cold-water rinse and draining. Free-rinsing performance supports that final stage; it does not mean the equipment can be used without rinsing.
How should the concentrated powder be stored and handled?
Keep it dry in its tightly closed original container, cool, well ventilated and protected from sunlight. Store it away from acids and do not mix it with other cleaning chemicals. Crystal causes severe skin burns and eye damage, may irritate the respiratory system and is toxic to aquatic life with lasting effects. Follow the safety data sheet for protection, handling and disposal.
