Washing dirty crates in a looping

In Maasdijk, Growers United has finally taken up residence in their new location at Honderdland. This means a lot of product is going in and out at the big player in cultivating and packaging greenhouse vegetables.

To keep all the crates used for this clean, Unifortes recently supplied  two washing installations. Together they are capable of washing 6400 crates per hour, with its four bands to supply the crates, Dennis Martens reports.

The dirty crates are entering both machines on double bands and are reversed in a looping, in which the more coarse pieces of dirt fall out of the crates.

Then the crates enter the machine, which is equipped with four modules, a pre-wash, two main wash modules and an after-wash module.

Most remarkable is the large filter for the pre-wash in the installation. The water from this module is pumped to another location, where it is filtered to 60 micron by a paper band-pass filter.

Dennis throws a glance in the paper band-pass filter, of which Growers United has two, one for each washing machine.

After intensive washing, for which Unifortes specially developed a validated disinfection module against the Tomato Brown Rugose Fruit Virus, it is time to dry the crates. Then the crates are turned over again and automatically stacked by Viscon automation.
