Pistachio Peeling and Drying Production Line
2026-08-11
This production line is specially designed for large-scale pistachio processing, covering the complete seven core steps from raw nuts to finished products: vibrating screening → high-pressure spray washing → soaking → flexible wet peeling → air circulation drying → gradient-temperature roasting → moisture-proof packaging. The entire line is made of food-grade stainless steel, with a PLC intelligent central control system that monitors temperature, humidity, and flow rate in real time, enabling fully automatic continuous operation. The wet-peeling station uses flexible rubber rollers, achieving a nut damage rate ≤2%. The drying section incorporates waste-heat recovery technology, reducing energy consumption by 18% compared to traditional equipment. The roasting zone allows customized eight-segment temperature profiles to precisely unlock the nuts’ natural aroma. The packaging end integrates metal detection and weight checkweighing, ensuring zero foreign matter and net weight error within ±1g. The line occupies 20% less floor space and reduces operator demand by 40%, supporting flexible capacities of 5–20 tons per day.
