With the rapid development of the health food market, the demand for protein bars as a convenient high protein snack continues to grow. For manufacturers, choosing a protein bar forming machine with stable performance and high efficiency is the key to ensuring product quality and improving production capacity. This article will analyze how to choose a high-quality protein bar forming machine from the perspectives of core technology, functional requirements, equipment parameters, etc.
The formula for protein bars is diverse and may include different textures of raw materials such as protein powder, nuts, syrup, chocolate coating, etc. When selecting a device, it is necessary to confirm whether it supports multi material mixed molding, for example:
-Can high viscosity or particle containing raw materials be processed?
Our P308 protein bar extruder can be used to produce hard materials, soft materials, large particle materials, dry materials, and difficult to shape materials, suitable for various types of materials.
-Is a temperature control system (such as heating/cooling modules) equipped to ensure the uniformity of syrup or chocolate coating?
We have developed and equipped chocolate coating machines for different types of protein bars in the market, which can be used to produce chocolate protein bars, thereby enriching the variety of protein bars and enabling manufacturers to gain more profits. We can also customize the hopper part of the protein bar manufacturing machine to be heated or cooled according to customer requirements, so as to ensure that the raw materials in the hopper do not deteriorate and the taste of the formed protein stick is not affected by the machine.
-Can the mold be flexibly replaced to adapt to different shapes (square, circular, two layer, etc.)?
Yes, our energy bar extruder can customize molds of different shapes and sizes according to customer requirements
Select matching production capacity based on the size of the enterprise:
Small businesses: Optional semi-automatic equipment (with a production capacity of about 100-300 kg/hour), low cost and flexible operation.
Most of our first-time customers choose the P307 small protein bar extruder, which has a small footprint and can produce approximately 200kg of energy bar per hour. The size and shape of the energy bar can be adjusted.
Medium and large enterprises: they need full-automatic production lines (with a capacity of more than 500 kg/h), integrated molding, cutting, packaging and other functions, and reduce manual intervention.
For factories with high production capacity, we have developed the P400 multi row protein bar extruder, which can produce 500kg of raw materials per minute. The equipment can extrude 2 rows, 4 rows, 6 rows or even more rows at once
High quality protein bars should maintain consistent weight and size to avoid non-compliance with product specifications due to equipment errors. Key focus:
Measurement system: Is high-precision sensor or servo motor used to control the filling amount of raw materials?
In order to ensure that the weight error of the produced energy bar does not exceed plus or minus 1 gram, we usually provide customers with a weight detector, which will remove date bars with excessive errors to achieve consistent product weight
Pressure uniformity: The stability of hydraulic or pneumatic systems ensures that there are no issues such as bubbles or fractures during the molding process.
Components that come into direct contact with food must comply with food grade stainless steel (such as 304/316L) standards, and the overall design of the equipment must be easy to clean to avoid cross contamination.
Our protein bar manufacturing machine is made of 304 stainless steel material for all parts in contact with food, which is not easy to rust and meets EU import standards.
If there are plans to expand the product line in the future (such as adding coatings or sandwich functions), choosing equipment that supports modular upgrades can avoid duplicate investments.
Many clients’ businesses will continue to grow in business and want to develop more products. Our clients will consider adding a chocolate coating machine and cooling tunnel behind the production line to coat the surface of the protein bar with a layer of chocolate.
