Dried fruit fruit cutting machine BCM400

halfhorizontal

Overview The BCM400 nut chopping machine converts whole roasted, cooled, out-of-shell nuts into calibrated, free-flowing granules by two-stage cutting and vibratory sieve classification. It produces dry granules for inclusion, topping and pre-processing; it does not produce paste.

Process suitability — when to exclude this machine

• Do not use with raw, moist, hot or in-shell nuts: moisture and released oil smear knives and the cutting chamber, requiring full disassembly.
• Not suitable if the process requires nut paste at this stage: cutting does not produce paste.
• Bypass this machine when the recipe requires whole nuts — feed the inclusion mixer directly.
• Do not exceed the rated throughput: feeding above 400 kg/h degrades cut consistency and increases fines.

Output fractions and downstream use

• Under 2 mm — fine particles and dust: intended for dilution in a pre-mixer and gradual addition to a ball mill for praline and nut paste production; adding dry fines too rapidly can clog pump inlets and extend refining time.
• 2–5 mm — small granules for inclusion mixers, chocolate inclusions and bakery toppings.
• 5–8 mm — medium granules for visible textured crunch in bars and praline products.
• Over 8 mm — coarse pieces discharged at the final outlet for applications requiring large nut pieces.

Two-stage cutting system

• Pre-crushing section: accepts whole roasted nuts from the feed reservoir and reduces them to fragments before guillotine cutting; reduces mechanical load on knives and limits fines generation.
• Guillotine cutting section (8–10 knives): shears pre-crushed fragments to target granule sizes; worn or blunt knives increase oil smearing and reduce uniformity.
• Vibratory sieve classification: separates chopped output into four calibrated fractions routed according to downstream needs.

Input requirements and throughput

• Input: roasted, dry, fully cooled, out-of-shell nuts only (peanuts, hazelnuts, almonds, pistachios, cashews, walnuts, dry biscuit inclusions).
• Unsuitable inputs: raw or high-moisture nuts, hot nuts, in-shell nuts.
• Throughput: 200–400 kg/h. Exceeding this range degrades cut quality and increases fines.

Where it is used in a chocolate production line The BCM400 is typically placed after roasting and winnowing and before destination processes: under-2-mm material is routed for praline and paste production via pre-mixing and ball milling; fractions ≥2 mm feed inclusion mixers for chocolate inclusions or bakery toppings; selected fractions can be delivered to a vibratory sprinkler for surface decoration. Whole nuts bypass the machine when whole-nut inclusion is required.

Wear parts, warranty and lead time Knives are the main wear parts; keep a spare knife set to avoid downtime. The machine carries a 1-year warranty against manufacturing defects (wear parts excluded). Typical lead time from order: 3–4 months.
