Core Equipment & Production Process
Each piece of equipment in the production line works in coordination to achieve a smooth and automated workflow, with detailed links as follows:
1.Temperature - Controlled Mixer
This is the starting point of the production line. It precisely controls the mixing temperature to mix protein powder, nuts, sugar, edible oil, and other raw materials evenly. The stable temperature control prevents the deterioration of heat - sensitive ingredients and ensures the uniform texture of the bar base, laying a solid foundation for the subsequent forming process.
2.Feeder
The automatic feeder transports the well - mixed raw materials to the forming machine in a quantitative and continuous manner. It avoids manual feeding errors and material waste, and the feeding speed can be adjusted according to the production rhythm to match the efficiency of subsequent equipment.
3.Sugar Cooking Pot
For candy bars and protein bars that need sweet syrup ingredients, the sugar cooking pot uses electromagnetic heating to cook sugar and water into syrup at a constant temperature. It features rapid heating and accurate temperature control, preventing the syrup from burning or crystallizing, and ensuring the proper sweetness and viscosity of the products.
4. Cereal bar Forming Machine
The machine shapes the mixed raw materials (and added syrup) into continuous bar blanks of fixed thickness and width. The forming mold can be customized according to product needs, supporting the production of various specifications of bars, such as 20g, 30g, and 50g, to meet different market demands.
5. Cutting unit &bar separating system & conveyor
Separating cutter is height adjustable, easy cleaning,
Separate motor driving, speed adjustable.
Product automatically separating
Vertical cutting, size adjustable.
Stainless steel quality, PU belt.
6.Chocolate Coating Machine and cooling tunnel
The separated and cut bars are conveyed to this machine for full or partial chocolate coating. It is equipped with an even coating system and a temperature - controlled chocolate melting tank, which ensures that the chocolate coating on the surface of each bar is thin and uniform without dripping. The coating thickness can be adjusted freely to meet the preferences of different consumers.
7. Full - Automatic Packaging Machine
The final step of the production line. It completes the operations of film wrapping, sealing, date coding, and counting for the chocolate - coated bars. The whole process is automated without manual assistance, which not only improves production efficiency but also ensures the hygiene of the products and extends their shelf life.
Key advandages
Ultra - low Labor Dependence
The entire production line realizes automated connection from raw material mixing to packaging. Only 1 - 2 operators are needed to monitor the equipment operation and supplement raw materials occasionally, which is much less than the 5 - 6 workers required by traditional semi - automatic production. It greatly reduces labor costs for enterprises.
Space - Saving Integrated Design
Compared with the traditional mode of combining independent large cutting machines and separate equipment, this integrated production line has a compact structure. The overall dimensions are optimized, reducing the occupied space by about 80%. It is easy to place even in small and medium - sized workshops.
Versatile Production Capacity
By adjust cutter and adjusting coating parameters, and changing raw material formulas, it can flexibly produce protein bars, nut candy bars, chocolate - coated cereal bars, and other multi - category products. It helps enterprises enrich their product lines without adding extra equipment.
Stable Quality & High Efficiency
The automated operation avoids the quality inconsistency caused by manual operation. The production capacity can reach up to 5000 pieces per hour. It can easily meet the needs of bulk orders while ensuring that each product has the same weight, shape, and taste.

Why Choose This Production Line?
This production line integrates automation, versatility, and space - saving features. It solves the problems of high labor costs, large space occupation, and unstable product quality in the traditional production of candy bars and protein bars. It is a cost - effective choice for both small - batch trial production and large - scale mass production. We provide a 1 - year warranty, site installation and commissioning, and 24 - hour technical support to ensure your production goes smoothly.
