Q: What is the complete process flow of a chocolate energy bar production line?
A: The core process is: raw material pretreatment (grain puffing / nut roasting / dried fruit dicing) → ingredient mixing → calendering and compaction → longitudinal and transverse cutting and slitting → filling injection (optional) → chocolate coating → cooling and shaping → metal detection → weight sorting → packaging and boxing.
Q: What are the key pieces of equipment in the production line?
A: Key equipment includes puffing machine, baking machine, mixing machine, calender, cutting machine, filling machine (for filled versions), chocolate coating machine, cooling tunnel, metal detector, and packaging machine. The filling machine can be selected according to product type; it can be omitted if there is no filling requirement.
Q: What is the production line's capacity range?
A: Small line: 100-300 kg/h, suitable for small-batch, multi-flavor production; Medium line: 300-800 kg/h, suitable for small and medium-sized food factories; Large line: 800-1500 kg/h.
Q: What are the vulnerable parts of the production line? What is the replacement cycle?
A: Wear parts and replacement cycles: Cutter (3-6 months), conveyor belt (1-2 years), coating machine nozzle (6-12 months), heat sealing knife (8-12 months), sealing ring (3-4 months).
Q: How to maintain the energy bar production line daily?
A: Clean the mixer, calender, coating machine, and other contact parts daily; check the lubricating oil level of the motor and reducer weekly; calibrate the temperature control, weighing, and metal detection equipment monthly; regularly adjust the conveyor belt tension to solve the problem of belt misalignment.
Q: Can the production line be compatible with the production of energy bars of different specifications?
A: By changing the cutting machine die, adjusting the calender roll gap width, and setting the conveyor belt speed, energy bars of different specifications with lengths of 10-20cm and thicknesses of 1-3cm can be produced to meet different packaging needs.
Q: What are the warranty period and after-sales policy for the production line?
A: The whole machine is covered by a 1-year warranty, with 24/7 technical support and on-site repair available; original parts are supplied for life, and free operation training is provided.
