Solar Pumpkin Dryer

Product Description

Solar Pumpkin Dryer by Rudra Solar Energy Pvt. Ltd. is an enclosed, multi-tray solar drying solution designed for the hygienic dehydration of fresh pumpkin into dried pumpkin slices, flakes, powder and other suitable value-added vegetable products.

The system combines direct + indirect solar heating with controlled/forced airflow to support organised moisture removal. Its enclosed drying chamber helps reduce direct exposure to dust, insects, birds and rain compared with traditional open-sun drying.

Pumpkin Processing Value Chain

FRESH PUMPKIN SORT WASH CUT/SLICE PREPARE LOAD SOLAR DRY GRADE PACK MARKET

A Solar Pumpkin Dryer can help farmers, FPOs, SHGs and food processors convert fresh pumpkin into dried and value-added vegetable products, supporting storage, transportation and downstream food-processing applications.

Drying Conditions

The 5080C specification represents the typical system range and should not be treated as a fixed recommended pumpkin-drying temperature.

Actual drying conditions and duration depend on:

• Pumpkin variety and maturity
• Initial moisture content
• Slice thickness and cut size
• Tray loading
• Airflow
• Ambient humidity
• Solar radiation
• Required final moisture
• Intended end product

Therefore, product-specific trials should be used to determine the appropriate operating conditions rather than relying on one fixed drying time.
