Hard Candy Production Line

KHRT-180 Automatic Hard Candy Production Line – Industrial-Grade Core Equipment for High-Temperature Cooking & Molding

 

This production line is an industrial-grade fully automatic equipment designed for large-scale hard candy production, following the real hard candy process logic of "high-temperature cooking → vacuum concentration → stretching homogenization → cooling & molding", which is different from the gel pouring mode of gummy candies.

 

Suitable for producing multi-category hard candies such as fruit hard candies, milk-flavored hard candies, filled hard candies, and transparent hard candies, it reduces the moisture content of sugar to ≤3% through high-temperature cooking at 150-160℃, and uses stretching homogenization technology to ensure crispy texture and stable shape of finished products. With a production capacity of 120-150kg/h, it is the core choice for food enterprises to build standardized hard candy production lines.

1. Raw Material Pretreatment: White sugar, glucose syrup and other raw materials are screened to remove impurities, accurately measured and mixed according to the formula;
2. High-Temperature Cooking: Mixed raw materials are injected into a vacuum cooking pot, cooked at 150-160℃, and vacuumized to remove moisture at the same time, cooking time 15-20 minutes;
3. Vacuum Concentration: Vacuum degree -0.08~-0.09MPa, concentrating the moisture content of sugar to ≤3% to avoid sanding and sticking of finished products;
4. Flavoring & Coloring: Adding food flavoring and coloring, stirring quickly and evenly (hard candy flavoring must be completed in the high-temperature stage to ensure flavor integration);
5. Stretching Homogenization: The sugar is repeatedly stretched by a stretching machine to make the molecular structure uniform, improving the crispy texture and luster;
6. Cooling & Molding: Cooling to 60-70℃ through cooling rollers (avoiding cracking due to excessive temperature difference), then molding by mold pressing or extrusion cutting;
7. Post-Processing: The molded candies are further cooled to room temperature by a cooling conveyor belt, and defective products are screened out to complete pre-packaging finishing.

1. Process-Specific Adaptation: Focus on the core processes of hard candy high-temperature cooking and vacuum concentration, avoiding redundant gummy gel equipment, with more efficient process;
2. Stable & Controllable Taste: Precise cooking at 150-160℃ + vacuum concentration, moisture ≤3%, ensuring crispy finished products without sanding, high batch consistency;
3. Flexible Molding: Supports compression molding (round, square, special-shaped) and extrusion cutting (strip, granular), molds customizable;
4. Industrial-Grade Capacity: 120-150kg/h capacity, 1000L large-capacity vacuum cooking pot, adapting to large-scale production;
5. Safe & Durable: Food-contact parts are made of 316 stainless steel (high-temperature and corrosion resistant), core components adopt SIEMENS motors, stable operation;
6. Energy Optimization: The vacuum cooking system saves 30% energy compared to traditional atmospheric cooking, and cooling rollers use circulating water for cooling, reducing operating costs.
