Gummy candies trace their origins to the year 1922 in Bonn, Germany, where Hans Riegel Sr, a confectioner, founded the Haribo company. Drawing inspiration from the trained bears he attended at street festivals, he made a fruit-flavored gelatin candy which he called “Dancing Bear.” Early gummies were produced using an early form of starch mogul systems where molds were made from trays of cornstarch.
As the popularity of gummy bears and other gummy shapes grew in the 20th century, s the demand for more efficient production methods spurred innovation in manufacturing equipment. This expanded demand led to the creation and installation of automated, high capacity gummy machines, which remain a staple of the industry.
The reasons why modern gummy manufacturing equipment is critical to business operations is clear. It ensures brand loyalty by maintaining product uniformity in taste, texture, shape, and size. It also enhances the brand's image. Advanced gummy manufacturing equipment also ensures accurate dosing, an important factor in the rapidly emerging market for fortified or nutraceutical gummies that contain vitamins, minerals, CBD, or other active constituents. Additionally, automation boosts efficiency, lower operating costs, enhances cleanliness, and complies with safety standards, thereby meeting global market business requirements.
The manufacture of gummy candies is an example of a technological process consisting of several stages from concept to realization. Candies have to be manufactured in multiple stages to ensure the creation of the required final output.
The mixture used to produce gummy is a combination of sweeteners, gelling agents, acids, flavorings, and colorings.
Syrup sweeteners use a combination of sucrose, corn syrup and glucose to ensure taste and to prevent the formation of sweet crystals.
Translucent chewy products use a mixture of gelling agents such as gelatin which is the conventional choice. Gelling agents such as pectin which is a type of plant can also be used alongside with modified starch to introduce the vegetarian options.
Citric acids alongside with malic acids are used to augment sweet flavors and introduce the sour taste as well.
Flavors and colors come from a source that is natural as well as a source that is artificial to ensure a greater range of products.
Depositors, or gummy maker machines, have one primary purpose: to conveniently and accurately deposit liquid gummy slurry into prepared molds. The initial step of this process is the cooking system, which blends and heats the components to the requisite temperature to create a homogeneous slurry. The slurry is then discharged, and the depositor, which has nozzles to meter a definite quantity to their respective molds, fills the molds to a precise volume of mixture. After the molds are filled, they are taken to a cooling tunnel through which they are transported, allowing the gummy candies to set. Once this step is complete, the gummies are demolded and prepared for packaging.
Mixing and Cooking: Ingredients are added to a mixing basin and cooked to a specific temperature while stirring. Mixtures are cooked to a predetermined temperature and Brix (sugar content) level for optimal viscosity.
Adding Ingredients: After the base slurry is cooked and cooled, flavors, colors, and acids are added. For nutraceuticals, active ingredients are added in this step as well.
Depositing: The last slurry is transferred to the depositor, a device that fills molds by injecting the slurry into them. Molds are made of silicone, metals with a non-stick coating, or created in a starch mogul system.
Cooling and Setting: The molds are placed in a cooling tunnel where chilled air solidifies the gummies. The time and temperature varies depending on the gelling agent and the size of the gummy.
Demolding: After cooling the gummies are removed from the molds. In systems that do not use starch the shapes are usually ejected by compressed air or mechanical ejectors.
Finishing: The last process is coating the gummies with oil or sugar to prevent them from sticking as well as add a matte texture.
Packagin: The gummies are weighed and placed in their final box.
The production lines that create gummies include different machines that each perform a specific function. The type of gummy that is produced and the scale of operation will determine the configuration of the production line.
The modern gummy production lines must have a depositor as this is the core of the production line. There are two primary types:
Starch Mogul Lines: This is the traditional method where molds are made directly into trays of cornstarch. Starch has the additional benefit of moisture absorbing and thus dehumidifying the setting process. This method is flexible but very messy and needs additional equipment to condition the starch.
Starchless Mogul Lines: A more modern approach that utilizes molds made of silicone or metal. These lines are neater and take less space. They are gaining more traction especially for nutraceutical gummies where starch cross contamination is a problem.
Gummy Candy Mixers and Cookers
These units can only mix and cook at very low levels as gummies have very high slurry viscosity. A pre-mixer will typically mix the raw materials, and a pump will take the mix to a cooker. In large-scale operations, continuous cookers are more common and help maintain a steady flow of slurry to the depositor.
As for the main elements, the complete production line contains the following additional equipment:
Cooling Tunnels – They are long, refrigerated chambers that help in regulating the setting process.
Sugar or Oil Coating Drums – They are the turning barrels that uniformly coat the gummies with a layer of coating.
QC Systems – Vision systems, as well as metal detectors that scan for substandard gummies for defects and contaminants, are part of the packaging.
Packers - They are multi-head weighers and baggers or bottling lines, which perform the last step of automating packaging.
Staying competitive in the market requires embracing innovations in the processes and optimizing production lines. To achieve this goal, manufacturers have to innovate continuously and improve the efficiency and development of their products.
Integrating automated systems that monitor and adjust the parameters of the processes, like temperature, flow, and PLCs (Programmable Logic Controllers) that manage the whole line, improves efficiency. Downtime and safeguarding the hygiene of the product can be attained through proper sanitation and regular maintenance.
The industry is undergoing rapid change. Some of the most recent innovations include advanced cooking systems that reduce energy consumption; 3D printed molds for faster prototyping of new shapes, and even more precise servo-driven depositors. For R&D, “kitchen” systems that can produce small, trial sized batches are in greater demand.
Nutraceuticals have become a major product line because of the increasing focus on health, and so have gummy products. Other than precise, repeatable dosing of active ingredients, the production of this product line also requires specific manufacturing equipment, like depositors that do not use starch. This method is often preferred to maintain hygiene and avoid the destruction of sensitive compounds.
Just like at the start of the process, the last steps in the process go hand in hand. Proper packaging and distribution channels are also key in ensuring the product reaches the target audience in the most optimal and safe manner.
Moreover, packaging also serves a protective function in the preservation of the gummy, protecting it from moisture, light, and physical damage. Packaging also informs the buyer of the ingredients and the nutritional values of the gummy. Furthermore, packaging is a marketing tool on the retail shelf. It also has child-resistant closures, which are a legal requirement for certain medicated or high-potency gummies.
For gummies, the common packaged formats are stand-up pouches, jars, and blister packs. The packaging material must maintain the shelf life of the product as well as prevent the gummies from clumping together by providing a barrier to moisture and oxygen.
Even with modern tools, the challenges associated with gummy manufacturing persist. Achieving quality and uniformity in production demands unrelenting attention.
Effective quality management in gummy production starts with the system design. This entails evaluating the quality of raw materials, overseeing production at predetermined critical checkpoints, and evaluating the finished product with respect to quality parameters such as weight, texture, appearance, and potency (for nutraceuticals).
“Gummy Sweating”: Excess surface moisture on the gummy product due to incomplete cooking of the product or excessively humid conditions.
Stickiness: Resulting from improper ratios of sugar to syrup, as well as lack of sufficient coating.
Variation in Texture Uniformity: Caused by variations in the cooking time and temperature as well as the quality of the ingredients.
Through an appropriately structured manufacturing process, most of the gummies’ challenges can be resolved. Installing modern automated machinery with sophisticated process control and monitoring systems will ensure the most optimal consistency in quality and efficiency in operations. Such a system integrates design with production, and collaborating with an experienced supplier aids in recipe and process design.
The expansion of the gummy sector is a direct result of customer preference for both pleasurable sweets and novel health products. The gummy machine illustrates the engineering prowess that elevates a basic confectionery item into a technologically advanced and monetarily lucrative asset. Companies seeking to thrive in the industry must have deep knowledge of the equipment as well as the production techniques. This knowledge is more than just an asset; in this case, it is a crucial requirement.
