The key to food processing lies in the color, taste, nutritional value, and ultimate market competitiveness of the food.

Guoxin understands the stringent requirements of different food categories for drying processes. We not only provide equipment, but also offer comprehensive, customizable drying solutions from pre-treatment to finished product packaging.

Food Processing drying machine

I. Fruit & Vegetable Drying Solution: Locking in Natural Color and Nutrients

Problems:

When making dried mango, banana chips, dried strawberries, or crispy mushrooms and okra chips, traditional sun-drying or high-temperature drying easily leads to:

• Browning, resulting in poor appearance.
• Significant loss of heat-sensitive nutrients such as vitamins and anthocyanins.
• Altered flavor, loss of umami.

Solution:

• Equipment Combination: Heat Pump Dryer + Pre-treatment Production Line
• Heat Pump Dryer: Utilizes low-temperature (typically 35-65℃) closed-loop drying to maximize the preservation of the natural color, original flavor, and over 90% of nutrients in fruits and vegetables. Gentle air convection ensures even moisture evaporation, preventing surface hardening.
• Supporting Equipment: Fruit and vegetable washing machine ensures raw material cleanliness; blanching machine deactivates enzymes, a crucial step in preventing browning and locking in color;  slicing/dicing machine ensures uniform cutting and simultaneous drying.

Benefits:

• Product Premium: The produced dried fruits are vibrant in color, plump in shape, and have a soft or crisp texture, making them more competitive in the high-end market.
• High Energy Efficiency: Heat pump technology saves over 60% more energy than traditional electric heating, significantly reducing your production costs.
• Large-Scale Production: Our mesh belt continuous dryer can operate 24 hours a day, perfectly matching the needs of large-scale fruit and vegetable processing production lines.

II. Meat/Seafood Drying Solution: Ensuring Safety and Flavor

Problems:

The production of beef jerky, pork jerky, dried scallops, and dried fish involves complex processes:

• Precise control of temperature, humidity, and airflow at different stages is required to complete maturation, shaping, and deep drying.
• Extremely high hygiene and safety requirements necessitate the elimination of cross-contamination and effective inhibition of microbial growth.
• A uniform texture and unique chewiness are required.

Solutions:

• Equipment Combination: Multi-layer mesh belt dryer + Intelligent control system
• Temperature and Humidity Control: The equipment incorporates high-precision sensors and a PLC control system, allowing for programmable settings of multiple drying stages (such as preheating, color development and maturation, dehumidification and shaping, and final drying), accurately replicating the optimal process curve.
• Hygiene: Contact parts are made of stainless steel with seamless welding, facilitating thorough cleaning. A sterilization module can be added for pasteurization before and after drying to ensure microbial standards are met.
• Uniform Drying: A forced convection system ensures consistent temperature and humidity throughout the drying chamber, preventing localized over-drying or over-wetting of the product.

Benefits:

• Safety and Compliance: A production line compliant with international food safety standards such as HACCP and FDA ensures your products can be processed smoothly.
• Flavor Preservation: Precise process control guarantees consistent and authentic flavor and texture in every batch.
• Energy Saving and Efficiency: Automated operation reduces reliance on skilled workers and minimizes human error.

III. Nut and Seasoning Drying Solution: Uniform Heating

Problems:

When roasting almonds, cashews, or drying chili peppers, herbs, or garlic slices:

• Uneven drying results in some products being burnt (producing a bitter taste) while others remain uncooked (prone to mold).
• Localized overheating damages oils and volatile aromatic compounds, causing nuts to lose their crispness and spices to discolor.
• Inconsistent batch quality affects brand reputation.

Solution:

• Equipment Combination: Microwave Drying and Sterilization Equipment + Mesh Belt Dryer
• Microwave Drying Advantages: Microwaves penetrate the interior of materials, causing moisture to evaporate from the inside out, achieving rapid and uniform heating and drying, completely solving the problem of localized overheating. Especially suitable for the final drying and sterilization of high-value nuts and seasonings, with extremely high efficiency.
• Multi-layer Mesh Belt Dryer: For materials requiring long-term slow drying, our unique circulating air duct and turning design ensure that the material is evenly processed as it moves through each layer of the mesh belt, ensuring no dead spots in drying.
• Low-Temperature High-Volume Option: For delicate herbs, petals, etc., we can configure a low-temperature high-volume system to maintain a low temperature while rapidly dehumidifying.

Benefits:

• Superior Quality: Every nut is crisp and delicious, every spice is vibrant in color and rich in aroma.
• Reduced Losses: Near-zero scorching and mold, directly improving your yield and profit margin.
• Flexible Production: The equipment’s parameters can be easily adjusted to adapt to the production of different types and batches of nuts and seasonings.
