Can Washer

What is can washer and it’s uses?

The internal and external surfaces of the cans are cleaned and prepared by the can washer.

Can washers are used in the many stages of the beverage and food can industry. Can washers have a maximum cleaning capacity of 6,000 cans per minute. Use our innovative Belt Vacuum System to recover and recycle valuable chemical resources.

The Can Washer has removable roof panels that allow access to the full length of the washer inside, reducing the time and cost of maintenance.

For ease of maintenance and operator safety, our spray risers have full-length guide rails and innovative quarter-turn quick couplings.

When using a bolted joint such as a bolt and nut, a washer is a mechanical component typically used to prevent the bolt from loosening or to spread the weight of the nut or bolt head over a larger area. Soft steel narrow flat rings are often used for load distribution.

Types of can washer

Can scrubber

These can washers are very simple in design and operation. A cylindrical hard nylon fibre brush "A" rotates around its axis as shown in the illustration and is driven by a small electric motor of typically 0.5 to 0.75 HP. The attached gear drives another brush "B". On one side of the scrubber there is a single stationary brush "C", which matches the shape of the can.

Cans are often washed in a scrubber using the following method:

• Pour the required amount of detergent into the wash after filling.

• The solution should be heated to 45-50Oc.

• Turn on the motor of the can scrubber to rotate the brushes.

• The can should be taken out of the drip saver and inserted into the scrub brush "A" from the free end side.

• Hold the can long enough for the contents to fall out.

• While the rotating brush "B" and a stationary side brush with a unique design scrape the outside of the can, brush "A" cleans the inside of the can.

• Remove the cans and rinse them in cold water.

• Check the cleaning progress with clean hands.

Can Steaming Block

After manually cleaning the cans, the sterilisation is carried out either by steam sanitization through steaming blocks or by spraying a cold sanitizer solution.

Design and Function

This apparatus is specifically made to hold cans upside down. The cleaned can is sterilised by being injected with live steam until it gets hot using paddle-operated steam and water jets.

The main safety measures required when using a steam block are to ensure that the flush/steam injection valve is working and that steam is being injected. To prevent burns, the operator's safety must be ensured when handling the hot can. Cans are sometimes held by the operator for short periods of time, which can lead to inefficient operations. The can should be in the correct position before the rinse or steam valve is opened to prevent accidents from hot water splashes. A steam pressure of 2 to 3 kg/sq cm is sufficient to achieve the desired result.

Maintenance

• Check and clean the nozzle holes regularly.

• Check and adjust the spring tension of the paddle valve.

• Maintain cleanliness and clean drain holes.

Rotary Can Washer

These can washers are automatic or semi-automatic and effectively rinse, clean and sterilise cans. The machine features are listed below.

Construction

This type of washer is made of very simple materials and carries the cans on a large rotating table or carrier (Fig.). Cans with irregular shapes can be cleaned without any safety concerns. These are relatively small machines, available in various sizes to handle small to medium numbers of cans.

Check the effectiveness of the cleaning as a precaution. Dented or heavily soiled cans should be scrubbed in a can scrubber before loading into a rotary can washer.

Maintenance

• Pumps and jets, like other can washers, require frequent maintenance.

• Lubricate moving parts daily or as recommended by the manufacturer.

• Inspect and maintain the stuffing box, oil seal and water seal.

• Close all doors except the entrance and exit.

Straight-through can washer

The washer contains compartments for rinsing, detergent spraying, hot water rinsing, steaming and air drying.. The cans are carried to the exit door by steel or plastic chains specially designed to grip and carry the can. In other types of moving systems, the cans are moved from one position to the next by a ratchet. From the entry door, the can moves upside-down to the rinsing area, where loose soil and some dirt are washed off by warm water injected from below and from the other sides. These cans are then moved to the rinsing section where a hot rinsing solution at a concentration of 0.5 to 1% is sprayed over the inside and outside of the cans to completely remove the soil.

The hot water rinse stage removes detergent and soil residues from these cans. The cans are now thoroughly cleaned and transferred to the steam area for sterilisation. Finally, the hot cans are dried in the air drying area. By using a suitable attachment, the overturned cans are returned to their upright position with their mouths open before reaching the exit door.

How does a can washer work?

It uses centrifugal force to move the particles to the bottom of the tube. In the above processes, both processes use centrifugal force and work in the same way. So we can say that the working principle of the washing machine is centrifugation.

Maintenance and care for can washer

• Water hoses should be replaced. Inspect hoses regularly for signs of bulging, cracking, fraying and leaks near the ends. As part of a preventive maintenance programme, replace the hose every three to five years or whenever a problem is detected.

• Adjust the unit. To prevent the hose from kinking, make sure there is at least four inches between your washing machine and the wall.

• Keep the appliance level. A washing machine that is not level can cause damage to the machine or floor during the spin cycle by rocking, vibrating or moving across the surface.

• Turning the feet anti-clockwise to raise the washing machine and clockwise to lower it helps to maintain balance.

FAQs: Can Washer

Q. What are the different types of can washer available

Ans. A can washer uses 14 gallons of water per load, while a standard washing machine uses 20 gallons of water per load.

Q. Can a can washer be used to sanitize containers?

Ans.

• Rinse the outside of the canister to remove dirt and debris.

• Use detergent and water to clean the outside of the hopper.

• Use a high pressure spray hose for harvesting containers.

• Use clean, potable water for rinsing.

Q. What are the typical cleaning cycle time for a can washer?

Ans. An average wash cycle typically takes between 50 and one hour to complete. However, depending on the size of the load and the cycles or settings you choose, this time may be shorter or longer.
