Machine Modules

Controlled Intake Module: Speed-adjustable food-grade conveyor that ensures a uniform, single-layer product inflow to prevent line congestion.

High-Turbulence Wash Tank: High-pressure air blowers that generate strong water currents to flush residues out of dense florets, with an isolated bottom waste chamber.

Elevating Spray Station: Precision overhead nozzles that apply a final freshwater or sanitizing rinse as product leaves the tank.

Vibratory Dewatering Deck: High-frequency, low-amplitude shaker that rapidly removes surface water without causing floret bruising or bud shattering.

Eco-Filter & Recycling Hub: A heavy-duty water conservation station that continuously traps floating debris, separates dense sand, and pumps filtered water back to the main tank, saving up to 70% of fresh water.

FAQ

Q: Does the washing process damage or break the delicate broccoli florets?

A: No. The system uses water bubble buoyancy and low-impact high-pressure sprays specifically calibrated for fragile vegetables. The vibratory dewatering and roller grading systems are engineered to prevent drops or harsh impacts, keeping the florets intact.

Q: How does the machine remove insects and soil trapped inside the dense broccoli heads?

A: The machine utilizes an adjustable high-volume air injection system in the washing tank. This creates an intense under-surface bubbling effect that gently forces open the dense structure of the broccoli, flushing out hidden insects, dirt, and chemical residues.

Q: Are all materials used safe for food production in the US and EU?

A: Yes. Every component that comes into contact with the broccoli is manufactured from food-grade SUS304 stainless steel, and all conveyor belts, plastics, and seals are fully FDA and NSF-compliant.

Q: What is the typical lead time for a standard or customized broccoli processing line?

A: A standard configuration line typically requires 25–35 days to manufacture. Custom OEM setups requiring specialized factory layouts or specific electrical component brands take approximately 45–60 days.

Q: Can the grading system be adjusted for different broccoli sizing requirements?

A: Absolutely. The grading rollers feature an easily adjustable mechanism. Operators can modify the gap spacing via manual controls or a digital PLC interface within minutes to accommodate changes in harvest sizing or different retail packaging specifications.

Q: How do you handle electrical compatibility for factories in North America or Europe?

A: During the engineering phase, we customize the electrical panels, motors, and PLC systems to match your exact regional requirements-whether that is 460V 60Hz 3-Phase (common in the US) or 400V 50Hz (common in Europe), using UL/CE certified components.

Q: What kind of maintenance is required for this machinery?

A: The machine features an open-frame, hygienic design that allows for rapid daily washdowns. Bearings are waterproofed, and the water filtration system uses easily removable mesh screens that can be cleared without tools during shift changes.

Q: What is your warranty policy?

A: We provide a comprehensive 12-month warranty covering all mechanical and structural components. In the event of a part failure, we ship replacement parts via priority international express at no cost to you during the warranty period.
