Pistachio Dehumidifier

Stair-Type Pistachio Dehumidifier

The stair-type Pistachio Dehumidifier is a vital piece of equipment in semi-mechanized pistachio processing lines. It’s designed to reduce the surface moisture of pistachios after washing, playing a significant role in improving visual quality and increasing the efficiency of the dryer. The de-watering machine, utilizing a heating system and continuous stair-like movement, uniformly reduces pistachio moisture. By performing this initial preparation, it accelerates and optimizes the subsequent drying process.

Key Features and Benefits

• Reduces Surface Moisture: Prepares pistachios before they enter the dryer.
• Enhances Appearance: Increases the transparency and aesthetic appeal of the pistachios.
• Boosts Dryer Efficiency: Improves the performance of drying systems by removing excess moisture.
• Durable & Hygienic Construction: Made entirely of stainless steel, resistant and sanitary, suitable for food industries.
• Optimal Energy Consumption: Can use either gas or diesel burners.
• Adjustable Retention Time: Allows control over how long pistachios remain in the machine by regulating the output.
• Versatile Application: Suitable for both home and industrial scales (4 to 8 meters).

How It Works

After the pistachio separation stage in the water basin, the product enters the de-watering machine. Here, pistachios are placed on mesh stainless steel steps and heated from below by the heating system. The continuous movement of the pistachios on the steps, combined with controlled heat, causes their surface moisture to evaporate, preparing the product for the final drying stage. If the workload allows, the retention time of pistachios can be extended by temporarily closing the machine’s outlet, thereby removing more moisture.

Machine Application

• Suitable for semi-mechanized pistachio processing lines.
• Used in pistachio receiving terminals, processing workshops, and home units.
• 4-meter models: Ideal for home use.
• 6 and 8-meter models: Suitable for industrial lines and large processing terminals.

Important Notes

• The de-watering machine alone is not sufficient for complete pistachio drying. It must be followed by a hot air drying process until the final moisture content reaches 4% to 6%.
• Using the de-watering machine reduces fuel consumption and increases efficiency during the final drying stage.
