Professional Blueberry Washing Machine

The blueberry washing machine is a customized cleaning device specifically designed for delicate berries such as blueberries, goji berries, and cranberries. It employs a unique hydraulic and bubble-based cleaning technology to efficiently remove surface dust and impurities while minimizing physical damage to the fruit, effectively controlling cracking and skin breakage rates. It is a key piece of equipment in the pre-processing stage of berry processing.

A Cleaning Solution Tailored for Delicate Berries

Our equipment combines gentle cleaning mechanics with precise water circulation control, ensuring a perfect balance between cleaning effectiveness and fruit integrity.

Permeable Bubble Tumbling Cleaning System

• Microporous aeration pipes at the bottom of the tank generate uniform, dense fine bubbles. As these bubbles rise, they agitate the water flow, causing the blueberries to tumble and separate without severe mechanical friction, achieving efficient impurity removal without damaging the skin.

Adjustable Low-Pressure Spray System

• Multiple rows of fan-shaped spray heads are arranged above the equipment, using circulating filtered water for low-pressure spraying. This provides a secondary rinse to the floating blueberries, washing away suspended impurities, while also lifting and conveying them.

Impurity Separation and Water Circulation Filtration System

• During the washing process, light impurities such as leaves and stems are carried away by the overflowing water, while heavy impurities such as mud and sand settle in a specific collection tank. Equipped with multi-stage filtration tanks (such as drum screens and sedimentation tanks), the washing water can be recycled, significantly saving water.

Food-Grade Materials and Hygienic Design

• All parts in contact with water and materials are made of SUS304 stainless steel. The equipment structure is smooth and without dead corners, ensuring thorough drainage and meeting the highest hygiene standards for food processing, facilitating CIP cleaning.

Modular and Customizable Length

• The modular design allows the washing tank length to be customized according to the customer’s hourly production requirements (e.g., 500kg/h – 5000kg/h), and it can be easily connected to upstream and downstream elevators, dryers, and sorting machines.

GELGOOG’s Blueberry Washing Machine’s Core Advantages

Extremely Low Fruit Damage Rate:Avoiding the wear and impact on the blueberry skin caused by traditional brushes or powerful vortexes, the cracking rate can be controlled below 1%, directly guaranteeing your yield and economic benefits.

Excellent Cleaning Results: The three-dimensional rinsing effect of bubbles and water flow effectively removes dust, pollen, insects, and some pesticide residues from the surface of blueberries, resulting in a more thorough cleaning and providing clean raw materials for subsequent processing (such as freezing, drying, and jam making).

Highly Efficient Water Use: The built-in circulating filtration system can save up to 70% of water consumption, making it particularly suitable for areas with scarce water resources or strict environmental requirements, significantly reducing production costs.

Stable and Reliable Operation: The simple mechanical structure and high-quality water and air pumps ensure long-term stable operation of the equipment in high-humidity, continuous working environments with a low failure rate.

Experts Focused on Cleaning Delicate Fruits

Choosing GELGOOG machinery means partnering with an equipment expert who deeply understands the characteristics of small berries.

1. We understand the differences in tolerance among different varieties and ripeness levels of blueberries and can provide optimal parameter recommendations for water pressure, air pressure, and cleaning time.
2. We can provide a complete pre-processing line: “Lifting → Cleaning → Drying → Sorting,” achieving seamless integration.
3. Our equipment is widely used in blueberry growing regions and processing plants worldwide, and its gentle yet efficient characteristics have earned high praise from our customers.

Main Applications:

• Cleaning before processing and packaging fresh blueberries
• Pre-processing cleaning for frozen blueberries (IQF)

• Cleaning of similar berries such as goji berries, raspberries, and blackcurrants

FAQ

Q: How gentle is this washing machine? Does it really prevent blueberry skin breakage?

A: Extremely gentle. It relies on air bubbles and gentle water flow instead of abrasive brushes or violent agitation. The damage rate (mainly caused by pre-existing defects) is typically below 1-2%, which is significantly lower than conventional methods.

Q: Can it remove pesticides from blueberries?

A: It is primarily designed for removing dust, soil, and physical contaminants. While the washing process can help reduce some water-soluble surface residues, it is not a specialized “pesticide removal” machine. For deep cleaning, optional ozone water injection systems can be integrated.

Q: What about leaves and stems? Can the machine remove them?

A: Yes. Light impurities like leaves and stems typically float and are removed by the overflow system at the water surface. Heavier debris like sand and stones settle in the sediment trap. For stubborn floating debris, an optional rotary screen or paddle remover can be added.
