The definitive solution for premium finishing and precise packaging.
The value of raisins in the end market is defined by cleanliness, appearance, and packaging accuracy. Our Washing and Finishing Line Model PUA 2000 L is an integral system that takes your product to a superior quality standard — delivering it not only clean and conditioned but also brightened and automatically weighed, ready for the most demanding markets.
A detailed eleven-stage process for an impeccable result:
- Controlled feeding: the process starts with a robust Hydraulic Bin Tipper with independent power unit, followed by a Dosing Feeder that ensures a steady, uniform product flow — essential for the efficiency of the entire line.
- Deep multi-stage washing: the fruit first enters a Rotary Pre-Washer, where a stainless-steel cylinder with water rain performs initial cleaning. It then passes to the Double Cascade Washer (Double Riffle Platform), where two recirculated water steps remove any remaining impurities and condition the raisin. Side inspection catwalk and stairs for safe access.
- Rinsing, drying and spacing: a Rinsing and Dewatering Vibrator with two sectors — first sector with recirculated water, second with a battery of nozzles for final rinse — applies a clean-water shower and recovers excess water. A high-speed Centrifuge (with stainless paddles and easy-clean perforated cylinder) removes surface water, leaving ideal moisture. Then, a Spacing Vibrator evenly distributes the raisin across the conveyor width, preventing clusters that hinder inspection.
- Full-coverage inspection: a wide Illuminated Inspection Conveyor, with side discard boxes, enables visual quality control under uniform lighting. Immediately after, a Collection Conveyor captures the inspected product and concentrates it for the next stage.
- Brightening and automatic weighing: the Brightening Elevator with Automatic Weighing (Oil Coating Auger) transports the raisin through a stainless-steel auger while a dosing pump applies the exact amount of brightening oil (with temperature-controlled oil tank). At the discharge, a hopper with high-precision load cell weighs the product in exact batches, programmed from a touch screen.
- Final output: a Transfer Conveyor delivers the weighed batches directly to the packaging area, synchronized with the brightener cadence to keep continuous flow unbroken.
Construction and sanitary philosophy:
All-stainless-steel construction with sanitary polish from the inlet to packaging — all product-contact surfaces meet food-grade standards. Sanitary white plastic belts and PVC-with-solid-polyester belting. Drives with oil-bath gearmotors and fully shielded three-phase motors. Frequency variators to regulate speeds in critical modules (vibrator, destemmer, centrifuge). Control panel included.
Albion technology benefits:
- High-value premium finishing: deliver a final product that is clean, bright, with ideal texture and moisture — visually standing out on the shelf.
- Automatic, precise weighing: the PLC + load-cell weighing system eliminates human error, reduces waste, and guarantees packaging with exact weight, meeting commercial standards.
- High industrial throughput: with a capacity of 1,800 to 1,900 kg/h, this line is designed for processors aiming to maximize production volume efficiently.
- Sanitary, robust construction: built with extensive use of stainless steel with sanitary polish in all contact zones, ensuring product safety and long equipment life.
- Pre-assembled and concatenated in our workshop before dispatch — the line arrives ready to install on-site.
- 12-month warranty on mechanical parts of our manufacture.
This line is a strategic investment that automates the final and most critical stages, securing consistent quality and full control over your finished product.
