Peanut Kernel Washing Machine | Nuts Rotary Drum Washer

This peanut kernel washing machine is a continuous automatic cleaning device specifically designed for shelled peanut kernels, suitable for large-scale, standardized food processing production lines. The equipment employs a drum spray cleaning structure combined with a water circulation system, ensuring thorough cleaning while effectively reducing water consumption.

Constructed entirely from 304 stainless steel, it efficiently removes surface dirt, dust, and impurities from peanut kernels. This makes it an ideal solution for peanut processing enterprises seeking to enhance pre-treatment efficiency and product quality. With a capacity of 1–1.5 tons per hour, it meets continuous production demands while maintaining superior cleaning quality.

Peanut cleaning machine application scenarios

The peanut kernel washing machine is primarily used in the pre-processing stage of peanut processing production lines, suitable for:

• Cleaning raw materials for deep-processed products such as peanut butter, peanut milk, and peanut powder.
• Cleaning before production of snack foods like fried peanuts and roasted peanuts.
• Bulk peanut kernel cleaning for agricultural processing cooperatives and food factories.

Additionally, this equipment is suitable for water spray cleaning of granular materials like broad beans, peas, and almonds. It enables continuous operation, adapts to various food processing scenarios, and enhances overall equipment utilization.

Advantages of peanut kernel washing machine

• High cleaning efficiency: continuous drum rotation combined with spray water flow enables rapid cleaning of large volumes of peanut kernels, maintaining stable output at 1–1.5 tons per hour.
• Energy-efficient and eco-friendly: built-in water tank and pump circulation system (pump power 0.75KW) effectively reduces water consumption.
• Minimal material damage: the gentle drum cleaning method prevents peanut kernel breakage, preserving integrity and appearance quality.
• Simple operation & maintenance: with a total power consumption of only 1.1KW, the machine features low energy use and convenient daily operation and maintenance.
• Hygienic & durable: the 304 stainless steel body resists corrosion and rust, meeting food hygiene production requirements and ensuring a long service life.

Industrial peanut washer working principle

The peanut kernel washing machine employs a drum spray cleaning method:

1. Shelled peanut kernels enter the stainless steel perforated drum from the feed end.
2. The drum rotates slowly under motor drive, causing the kernels to tumble continuously.
3. Simultaneously, a water pump sprays clean water into the drum interior. Impurities are removed through water flow agitation and friction with the material.
4. Wastewater and fine debris pass through the drum’s perforations, draining back into the water tank for recycling.
5. Upon completion, the inclined drum design combined with rotational movement automatically discharges the cleaned kernels.

The compact machine measures approximately 2500×800×1600mm, facilitating seamless integration into production lines with subsequent drying, grading, or other equipment.
