| | | A European food supplier recently set up a brand-new factory specifically for making filled pancakes, which are sold to a very large supermarket chain that has around 1200 shops.
In connection with the setting up of this new factory, the company approached BILWINCO A/S with regard to investing in a weighing/filling line.
Requirements for the machinery to have a high production capacity, fill perfectly, be hygienic and easy to clean, and use an automatic and cost-saving process were the top priorities and had to be met.

The task was to design a system for weighing and filling the diced ham and grated cheese in a specific designated area on the pancakes in order to achieve correct folding (see figure).
After being filled, the pancakes are folded by an automatic folding unit.
It was essential for the manufacturers of this equipment that BILWINCO was able to place the filling precisely within the designated area, because otherwise the pancakes cannot be folded correctly.
120 pancakes a minute
The reason behind this investment was the requirement for cost efficiency and high production capacity in order for it to be possible to meet the supermarket chain’s total needs in future.
The capacity is 120 pancakes a minute. Furthermore, excellent levels of hygiene and easy cleaning have been guaranteed.
Weighing/filling line
The weighing/filling line is fully automatic and the main features are the following units: Two storage hoppers which each transport a product (diced ham and grated cheese) to two Z-conveyors, and two BW128W type multihead weighers which are placed end to end. The first weigher receives diced ham from the first Z-conveyor and then weighs and places the cubes carefully and precisely in the designated area on the pancake. The other weigher weighs and places the grated cheese on top of the diced ham. Two filling tools ensure that both the diced ham and grated cheese are placed correctly. The pancakes are then folded before proceeding to the packaging station.
Hygienic platform
The two multihead weighers are placed on a BILWINCO hygienic platform with banisters, stairs and grating for discharging water during cleaning.
The platform has sloping and rounded surfaces so the product cannot settle on them. It is fitted with a plate to cover the opening for the discharge chute. Furthermore, the platform contains a washing station for cleaning each weigher’s buckets.
The design of the platform guarantees high levels of hygiene as well effective cleaning. All units are made from stainless steel with a sealing class of IP67; this means they can withstand cleaning using a high-pressure washer.
