Candy Bar Inspection System for Proper Label

The Challenge

Candy bars are a timeless staple of American family life. It doesn’t matter if you prefer crispy toffee centers, crunchy almonds, or warm caramel: these sugary snacks bring families together, whether it’s a grandparent sharing an old favorite with their grandkids, a nice treat at a company meeting, or a tasty Halloween surprise.

Candy bar production, though, can be a far thornier process. Candy manufacturers must vigilantly ensure that each type of bar is wrapped accurately, every time. Mistakes are not acceptable — not simply because of people’s differing tastes, but because food allergies to common candy bar ingredients, such as peanuts, mean that the slightest errors can result in deadly consequences.

So, when a company approached Wrabacon about producing a manual system to inspect, label, and wrap multiple types of candy s, absolute precision and accuracy were major requirements.

Custom Packing Solution for a Wholesale Artisan Bakery

The Challenge

Corn Cob Transport ConveyorPeople care immensely about the quality of their bread. Everybody loves the aromatic taste, smell, and feel of fresh-baked artisan bread — but few have the patience to prepare it from scratch. While frequenting the local bakery is one option, it’s not convenient for busy people on the move. A good middleground can be found in “parbaking,” wherein a bread product is partially baked, and then quickly frozen for storage. If done correctly, parbaking provides bread lovers with the look, taste, and feel of fresh bread, but none of the stress.

Packaging and providing parbaked artisanal bread products to customers, though, is a great deal more complex. Precision is necessary. Proper timing is everything. That’s why a local wholesale bakery, who specializes in parbaked frozen breads and bread rolls, turned to Wrabacon for solutions.

Fresh Corn on the Cob, Semi-Automatically Packed

The Challenge

Corn Cob Transport ConveyorWho doesn’t enjoy fresh corn? Easy to cook, affordable, and delicious, corn is an American institution: whether it’s being grilled for an Independence Day barbeque or served beside the Thanksgiving turkey, it’s a wholesome part of the nation’s identity.

That said, while growing corn is one thing, getting it onto store shelves across the nation — husked, packed, and fresh — is another process entirely. It’s not easy. Time is of the essence. Quality is demanded. The machinery itself has to be perfectly timed to match the speed of the human operators who are doing the husking, without missing a beat.

When a regional grocery store chain turned to Wrabacon for help with their corn-packing goals, a custom solution was needed — and Wrabacon delivered.

Custom CBD Oil Filling System

The Challenge

Wrabacon Custom CBD Oil Filling SystemThe rise of the CBD oil industry is one of the hottest new movements today. CBD, or cannabidiol, is still deemed controversial in some circles, but its usage in treating symptoms such as pain, anxiety, and movement disorders have drawn headlines. As of 2019, insiders have dubbed the growing demand for CBD oil products as “the next gold rush.”

However, manufacturing CBD products — as well as bottling the liquids, in the precise way that CBD oil requires — isn’t easy. Accuracy and meticulousness aren’t just niceties, but requirements, which makes mass production of these products uniquely challenging. That’s why a client turned to Wrabacon to create a system that could pump CBD oil into glass containers at high speeds, while not losing any accuracy. Once filled, the bottles would need to be capped and labeled.

Frozen Dough Ball Handling System

The Challenge

Frozen Dough SystemMore efficient processes mean more profit. This was exactly the case with a food manufacturer that wanted to increase packaging production for their frozen dough balls. They turned to Wrabacon requesting a system design and install that would receive frozen dough balls from a freezer, singulate them (separate them into individual pieces), and transfer them to two automatic bagging machines. This one change would help them increase their production capabilities dramatically.

Once bagged, the sealed bags would need to be transferred to a manual packing area where the bags were hand packed into shipping cartons. The cases are formed and transferred to the pack off area via another series of conveyors and elevators. Once packed, the cases need to be transferred to the case taper and palletizing area.

Filling Room Conveyors that Provide Reliability and Flexibility.

The Challenge

Filling Room Conveyors from WrabaconWrabacon was tasked with designing and manufacturing a series of conveyors that transport filled plastic containers from two existing fillers to two existing spot pack machines. The system needed to be designed so that each filler can feed each spot pack machine utilizing reversing belts. The containers will be produced at the rate of 180 per minute per filling machine. After the spot pack machine, spot packs need to be elevated and fed into a new palletizing line at the rate of 30 packs per minute.

A More Efficient Way to Process & Package Produce

Wrabacon specializes in developing creative packaging & automated conveyor system solutions for our customers that make time intensive tasks efficient and easy. A recent example is a custom designed and manufactured series of conveyors that drastically improved the efficiency of a manual produce packing operation for a regional distributor and specialty packaging company of organic produce.

Client Challenge

The client needed to be able to sort up to 6000 lbs. of produce an hour, grade that produce, and then package it in a variety of ways including loose product, cased product, and bagged product. Prior to the Wrabacon system, the grading portion of the operation was done by opening a box of produce and hand picking the good from the bad and transferring the bad product into a separate box which was then disposed of, which was time consuming and inefficient.

Artisan Cheese Manufacturer Turns to Wrabacon Ingenuity 
to Increase Production

Client Challenge:

An artisan regional cheese manufacturer faced a challenge. Their production line was completely manual and very slow. The problem was that the operators had to manually denest and place clam shell trays on a conveyor. Then they manually place finished cheese balls in the clam shell. Once this was completed, the operator would manually close the calm shell. They turned to Wrabacon to manufacture a packaging line that would transform their production line from a completely manual system to a semi-automatic packaging line.

The new system designed by Wrabacon consisted of a tray denester, a conveyor to transport trays to the operators, and an automatic lid closer. All equipment was built in stainless steel to meet the high demands and sanitation needs the food industry requires.

The Wrabacon Solution: 

  • Custom designed and manufactured a tray denester that denests plastic clamshells onto a moving conveyor at the rate of up to 30 per minute.
  • The system works with two tray sizes: 4” x 8.75” and 5.38” x 5.38” Each are denested with the long edge leading on the conveyor.
  • The trays are denested onto a conveyor where they will be manually filled by the operators.
  • After filling, they travel downstream to a lid closer that automatically folds and closes the lids prior to transferring to downstream equipment.

Denester Operation

Operators manually load the trays into an adjustable 45 degree twin hopper with the open side of the tray facing down. Pneumatic cups extend up to the trays, pull one from each stack, pivot down over the conveyor and then release the two trays. The trays travel on the conveyor with the wide edge leading. After placing the tray, the process repeats—picking and then placing the two trays onto the conveyor.

The denester utilizes a photo sensor to trigger the cycle. The sensor is mounted on the conveyor and when clear, the denester drops the trays onto the belt. The conveyor has variable speeds, so the denester rate is controlled by the speed of the conveyor. After denesting, the clamshells are manually filled with product.

Clamshell Closer Operation

After filling, the clamshells travel downstream to the closer with the lid open. A rail guide and partially closes the lid as it transfers to the conveyor. Once the lid is partially closed, a set of powered rollers snap the lid around the perimeter of the clamshell. Wrabacon designed the closer with power rollers since applying pressure to the top center of the lid might not seal the container properly.

The powered rollers are above the clamshell while a set of free spinning rollers are on the underside of the clamshell. By sitting over the two edges of the clamshell, the guides and rollers contact the edges of the container and ensure a proper closure. After closing, the clamshells transfer to downstream equipment for further processing. The closer is adjustable for the two tray sizes and can be easily adjusted via hand cranks and physical stops.

As part of this proposal, Wrabacon supplied (1) twin, adjustable hopper, tray denester with support frame, (2) 32” long denester hoppers that holds approx. 100 trays each, (1) main packing conveyor, (1) split belt clamshell closer and (1) control system.
