Automatic Carrot Washing and Drying Processing Line

Washing and Drying Processing Line Product Introduction

The Automatic Carrot Washing and Drying Processing Line provides an integrated solution for processing freshly harvested carrots from soil removal and washing through sorting and surface moisture removal.Fresh carrots are continuously conveyed into the cleaning system. A drum washing machine provides the primary washing stage, using drum rotation, water, and product movement to loosen and remove soil from the carrot surface. The carrots then pass through a brush roller cleaning section for additional cleaning and, when required, light surface peeling.

After cleaning, a sorting section can be used for inspection and removal of unsuitable materials. The carrots are subsequently transferred to a vibrating dewatering machine to drain free water before entering the air drying section for further surface moisture removal.The reference configuration has a total processing capacity of approximately 1000 kg/h and includes a hoisting machine, drum cleaning machine, hair roller cleaning machine, sorting machine, secondary hoisting machine, vibrating machine, and air drying machine. Conventional specifications can be customized according to production requirements.

Drum Washing Working Principle

The drum washing machine is particularly useful for freshly harvested root vegetables carrying significant amounts of soil.Carrots enter the rotating drum and continuously roll and move forward during processing. Washing water, carrot-to-carrot contact, and contact between the product and the drum assist in loosening surface soil.The reference manufacturer describes the drum rotation itself as contributing to both product movement and cleaning. Compared with relying only on a brush washer, introducing a preliminary drum washing stage can remove a substantial portion of loose soil before secondary cleaning.

Carrot Washing and Drying Process

1. Feeding and Conveying
Fresh carrots are loaded onto the feeding or hoisting conveyor and transferred continuously into the washing section.The conveyor helps maintain a controlled material flow between processing stages and reduces repeated manual handling.

2. Drum Washing
Carrots enter the rotating drum washing machine for primary soil removal.During rotation, the carrots continuously move and turn inside the drum while being exposed to washing water. The combined action of water, drum movement, contact between the carrots, and contact with the drum surface helps loosen and remove attached soil and surface impurities.

3. Brush Roller Cleaning
After drum washing, the carrots enter the brush roller cleaning machine for secondary cleaning.Rotating brushes contact the carrot surface while water can be used to carry away loosened soil and residues. Depending on the selected brush material and operating conditions, the section can be configured primarily for washing or for washing with additional surface peeling.

4. Sorting and Inspection
After cleaning, carrots can pass through a sorting or inspection section.This stage provides an opportunity to remove unsuitable material before downstream processing. The reference 1000 kg/h line includes a dedicated sorting machine.

5. Vibrating Dewatering
Washed carrots normally carry free water on their surfaces.
A vibrating machine helps drain and separate part of this water before the carrots enter the air drying section.

6. Air Drying
The carrots are transferred through an air drying machine where forced airflow further removes surface moisture remaining after washing.In this application, drying primarily refers to surface water removal rather than dehydration of the internal moisture of the carrots.
