Product Introduction
1. Overview
The Automatic Dehydrated Garlic Processing Line is a commercial turnkey solution designed to process fresh garlic into dehydrated garlic slices, flakes, granules, or powder. The complete line integrates garlic clove separation, dry peeling, washing, slicing, surface dewatering, air drying, and continuous heat-pump drying, with grinding and other downstream equipment available according to the final product requirements.
The core drying section features an energy-efficient 5-layer mesh belt air-source heat pump dryer, delivering precise temperature control, low energy consumption, and uniform drying while retaining the natural color, aroma, and Allicin content of the garlic.
The complete line can be customized according to raw material conditions, production capacity, final moisture requirements, garlic slice specifications, final product type, and workshop layout.
Typical Processing Flow:
Garlic Elevating & Feeding → Clove Separation → Dry Garlic Peeling → Bubble Washing & Rinsing → Garlic Slicing → Vibrating Dewatering → Surface Air Drying → 5-Layer Mesh Belt Heat Pump Drying → Optional Grinding → Packaging
2. Main Equipment & Functions
1. Automatic Garlic Elevator
The Automatic Garlic Elevator continuously feeds fresh garlic bulbs into the processing line and provides stable material transfer to the following equipment. It reduces manual handling and helps maintain a consistent feeding rate for continuous production.
2. Garlic Clove Separator
The Garlic Clove Separator gently splits whole garlic bulbs into individual cloves prior to peeling. Equipped with food-grade rubber rollers, it achieves a high splitting rate (>98%) with minimal clove damage, preparing uniform cloves for the peeling stage.
3. Air-Type Dry Garlic Peeler
The Air-Type Dry Garlic Peeler uses compressed air to remove the outer garlic skin without adding water during the peeling stage. This dry peeling method eliminates water consumption, prevents nutrient loss, and preserves the natural shelf life of garlic.
4. Garlic Bubble Washing Machine
The Garlic Bubble Washing Machine uses water circulation and bubble agitation to wash peeled garlic cloves and remove residual skins, dirt, and surface impurities. Gentle washing helps clean the garlic while reducing unnecessary mechanical impact on the product.
5. Precision Garlic Slicing Machine
The Precision Garlic Slicing Machine cuts cleaned garlic cloves into uniform slices according to the required product specification. Consistent slice thickness helps improve drying uniformity and provides a more consistent final product.
6. Vibrating Dewatering Machine
The Vibrating Dewatering Machine removes excess surface water from freshly sliced garlic through continuous vibration. By reducing free surface moisture before drying, it helps lower the moisture load entering the main drying system.
7. Air Drying Conveyor
The Air Drying Conveyor uses forced ambient air to remove remaining surface moisture from the garlic slices before they enter the main dryer. This pre-drying stage helps reduce surface moisture and improves material handling during the subsequent drying process.
8. 5-Layer Mesh Belt Air-Source Heat Pump Dryer
The 5-Layer Mesh Belt Air-Source Heat Pump Dryer is the core dehydration equipment of the line. Garlic slices are continuously conveyed through multiple drying layers while controlled hot air removes moisture. The multi-layer structure provides a larger effective drying area within a compact footprint. The drying temperature is adjustable according to the garlic slice thickness, moisture content, and drying requirements. Gentle, controlled drying helps reduce excessive heat exposure, supporting the natural color, pungency, and Allicin content of garlic while minimizing browning during dehydration.
9. Optional Garlic Grinding Machine
For customers producing garlic powder, an Optional Garlic Grinding Machine can be added after the drying section. The dried garlic slices are further ground into the required particle size before packaging. The grinding system can be configured according to the desired final product and powder specification.
3. Key Features of the Garlic Processing Line
1. Integrated Processing and Drying
The line combines garlic preparation, cleaning, slicing, dewatering, and dehydration into one continuous processing system. This reduces repeated manual handling between individual processing stages.
2. Continuous Multi-Layer Drying
The 5-layer mesh belt dryer provides multiple drying levels within a compact footprint. Garlic slices can move continuously through the drying system, making it suitable for higher-capacity production.
3. Heat Pump Drying Technology
The air-source heat pump system uses heated air to remove moisture from garlic slices, providing an energy-efficient and controlled drying process. Compared with conventional direct-fired drying methods, it operates without direct combustion inside the drying chamber, helping provide a cleaner drying environment. Adjustable drying conditions also help reduce excessive heat exposure and support the natural color, aroma, pungency, and overall quality of the garlic during dehydration.
4. Flexible Production Configuration
The processing line can be configured according to raw garlic quality, garlic slice thickness, required daily output, final moisture content, available factory space, and other production requirements.
5. Turnkey Engineering Support
DANUBE can provide the complete processing and drying line, including equipment selection, process configuration, factory layout planning, and customized production solutions.

5. Frequently Asked Questions (FAQ)
Q1: Can the drying temperature and speed be adjusted for different garlic slice thicknesses?
Yes. The 5-layer mesh belt dryer is equipped with a smart PLC control system. You can easily adjust the conveyor speed, drying temperature to match specific slice thicknesses (1.5 mm – 3.0 mm) and target moisture levels.
Q2: Does the dehydration process affect the natural color, flavor, or Allicin content of the garlic?
No. Traditional high-temperature direct-fired dryers often cause browning and destroy active heat-sensitive nutrients. Our heat pump drying system applies gentle, low-to-medium temperature multi-stage drying, which retains the garlic’s natural golden-white color, rich pungency, and vital Allicin content.
Q3: Can this processing line be customized for limited workshop space or lower ceiling heights?
Absolutely. DANUBE provides custom engineering services. We can adjust the belt length, number of drying layers, equipment order, and overall layout to fit your factory’s specific floor space and height constraints.
Q4: Is this line suitable for processing other agricultural products besides garlic?
Yes. By adjusting the slicer blade gaps and drying parameters, this versatile line can also process onions, ginger, horseradish, carrots, potatoes, and chili peppers, maximizing your equipment investment return.
