ProSweets 2019 Focused On Technology, Innovation


Cologne, Germany — Thousands of confectionery manufacturers descended on Germany last week to learn about the latest in packaging and processing technologies from suppliers to the confectionery and snacking industry. Following are just a few of the packaging and processing innovations on display during the four-day event.


Loesch Offers Option To Hermetically Seal Chocolate Bars

Loesch Verpackungstechnik’s RCB-HS wrapping head machine used to produce hermetically sealed bars of chocolate.

Loesch Verpackungstechnik presented its RCB-HS wrapping head machine used to produce hermetically sealed bars of chocolate. In addition to small chocolate items, the latest version of the LTM-DUO die-fold machine reflects the growing popularity of tightly sealed chocolate bars.

“The R series for small chocolate products and bars combines a premium look and ideal product protection in an end-to-end hermetically sealed pack,” says Loesch CEO Dr. Thomas Cord. “The extremely compact RCB-HS machine platform has been rigorously designed for top performance and handles the primary packaging in modern chocolate production reliably and flexibly.”

The RCB-HS operates continuously and produces the fold wrap in one wrapping head. It circumferentially heat-seals or cold-seals the packaging material as required, according to the company. The sealing jaws seal film against film, ensuring extremely tight packaging and preventing thermal damage to the products. Set-up time for a format changeover is around 60 minutes, while in most cases belt changes and cleaning can be carried out without the use of tools, Loesch maintains.

LoeschPack also presented the LTM-DUO. The latest generation of the flexible fold wrapping machine packs up to 215 bars of chocolate a minute in a primary wrap and an outer wrap. Alongside conventional packaging materials, the primary wrap can also use bio-degradable packaging film with an output of up to 180 bars a minute, the company claims. The outer wrap can be executed as a paper envelope from the stack or reel, or as a cardboard box.


Energy Savings Was A Top Priority On Chocotech’s Stand

Chocotech’s ECOGRAV offers substantial energy savings.

The ECOGRAV from Chocotech is a flexible gravimetric weighing unit with a buffer tank and an integrated continuous pressure dissolver which uses the moisture of the glucose (corn syrup) to dissolve crystal sugar (or sugar free ingredient i.e. Isomalt) without having to add any or little water. The result, according to the company, is substantial energy savings. The unit is ideal for hard candies, chewy candies, fondants, and cooked sugar solutions for bars and allows a dry solids level of up 90 percent to be achieved prior to cooking. This approach, the company maintains, substantially reduces the energy required compared to traditional processes which start the cooking step at 75 percent to 80 percent dry solids, resulting in steam savings from 30 to 70 percent. Other advantages, the company reports, stem from the flexibility of a gravimetrical weighing system, which enables easy recipe and ingredient changes and last but not least the savings of potable water in the recipe.

In addition, the company showcased its PRINCESS SUCROMASTER, a hygienically designed cooking and vacuum system for sugar and sugarfree hard candy. The standard system is designed with a static cooker type SUCROTWIST. The system on display included a dynamic thin film cooker type SUCROFILM, which the company says is ideal for hard candies which contain milk in the recipe. The system comes with a vacuum extraction screw and a specially designed dynamic mixer for adding color, flavor and acid into the cooked mass. It is also designed for; laminated, center filled, caramelized, sugar free, aerated, layered (multi-color) and medicated hard candy.


WDS Chocolate Production Line Focused On Medium, High Output

The WDS booth at ProSweets featured the company’s chocolate equipment.

A main highlight at the Winkler und Dünnebier Süßwarenmaschinen stand was the ConfecPRO type 670 chocolate production line. The plant meets the needs of manufacturers who want to target a medium to high output quantity – but at the same time are planning a subsequent growth-oriented expansion of the plant, according to the company.

“Concerning the ConfecPRO type 670, we are talking about a production capacity of up to 5,000 kg per hour. Important here is the wide range of different chocolate products that can be produced. The greatest possible product flexibility is a particular concern for our customers,” said WDS Managing Director Rainer Runkel. “For confectionery manufacturers, the ConfecPRO type 670 is definitely a future-oriented investment because the modular design allows for subsequent and easy expansion that can be carried out at any time and with very little effort.

Sales Manager Thomas Kleppel also pointed out the advantages to the customers: “This system is durable, of high-quality design that meets the highest hygienic requirements thanks to the EasyClean execution.”

When asked about the effort involved in converting to a different product, he explained: “From the very outset, the ConfecPRO type 670 was designed in such a way that changeover times can be kept as short as possible. This is due to, among other things, its particularly good accessibility, and the fact that almost all parts of the system that come into contact with the product masses can be replaced without any tools.”


Tomra Food Launches State-Of-The-Art Sorting Equipment

Ejectors remove faulty gummies on Tomra Food’s Nimbus sorter.

Tomra Food showcased both horizontal belt and vertical free-fall sorting equipment for gummies and delicate confectionery products at ProSweets 2019. The systems are designed to remove defective articles and foreign materials.

SmartPacker, TwistWrapper Featured By GEA

The OverlapSeal option on the Aquarius TwistWrapper hermetically seals the product to considerably extend the shelf life.

Highlighted by GEA during the expo was the SmartPacker CX250-S, a vertical form-fill-seal packaging system (VFFS) for high-speed packing of confectionery, snacks and nuts and the GEA Aquarius TwistWrapper for lollipops with its unique OverlapSeal option. The easy-to-open option provides unique added value to lollipop packaging.

The new SmartPacker CX250-S vertical bagger builds on its predecessors and integrates new technologies, which make it quicker and easier to use while providing increased production efficiency and improved bag quality, the company claims. The jaws operate with a high seal force – almost twice as high as the previous model – to enable gas-tight bags across a greater range of film materials. The jaws also create more accurate and stable longitudinal and cross seals for improved pack quality and presentation, according to GEA.

The low-drop design between weigher and jaw-head enables compact and high-speed filling and reduces the chance of damage to brittle products. The improved product-in-seal detection function helps facilitate uninterrupted production even if product fouls the seal area. The detection function automatically creates a double-bag to deter contamination or damage to the sealing jaws or knife, ensuring that the process continues.

The CX250-S produces pillow bags 70 to 250 mm wide and up to 0.3 kg in weight and can run up to 250 bags per minute.

The GEA Aquarius TwistWrapper has the OverlapSeal option, developed especially for the TwistWrapper. The hermetically sealed twist wrap style extends the shelf life of lollipops, particularly in environments with high humidity. A tear slit makes the OverlapSeal double-twist is easy to open. The machine uses less wrapping film during production when compared to other wrapping techniques, according to the company. The standard TwistWrapper 600 with OverlapSeal handles lollipop diameters from 18 to 30 mm and accommodates film reels up to 420 mm in diameter. The minimum wrapping speed is based on 600 lollipops per minute.

“Twist-wrapped lollipops give producers the opportunity to offer consumers another look and increase shelf appeal on the retail floor. Products attract more attention and can even make the lollipop look larger,” says Kees le Loux, GEA segment sales manager confectionery.
