1. Production Process and Common Quality Issues for Frozen Fruits

×

Process 1. Raw Material Reception & Pre-treatment

Key Processes:

Receiving fresh fruits, conducting initial quality inspection, grading, and removing unqualified products and impurities.

Main Equipment:

Conveyor Belts, Grading Machines, Sorting Tables.

Major Problems:

Inconsistent raw material quality, microbial contamination, foreign matter inclusion.

Process 2. Washing & Sanitizing

Key Processes:

Thoroughly washing fruits with clean water or disinfectant to remove soil, pesticide residues, and surface microorganisms.

Main Equipment:

Bubble Washing Machines, High-Pressure Spray Washing Machines, Ozone Sterilization Equipment.

Major Problems:

Incomplete cleaning leading to residues, substandard water quality, disinfectant residues.

Process 3. Peeling, Coring & Cutting

Key Processes:

Peeling, coring, dicing, slicing, or cutting fruits into desired forms according to product requirements.

Main Equipment:

Peeling Machines, Coring Machines, Dicing/Slicing Machines, Manual Operating Tables.

Major Problems:

Uneven cutting, high fruit loss, low manual efficiency, fast equipment wear.

Process 4. Blanching

Key Processes:

Briefly treating some fruits (e.g., strawberries, peaches) with hot water or steam to inactivate enzymes and preserve color and flavor.

Main Equipment:

Blanching Machines, Cooling Machines.

Major Problems:

Over-blanching leading to nutrient loss and texture softening, under-blanching leaving enzyme activity partially active.

Process 5. Draining

Key Processes:

Removing excess surface water from fruits to prevent large ice crystal formation during quick freezing, which affects product quality.

Main Equipment:

Vibrating Dewatering Machines, Air Drying Equipment.

Major Problems:

Incomplete draining affecting quick freezing efficiency, oxidation due to prolonged draining.

Process 6. Individual Quick Freezing - IQF

Key Processes:

Utilizing Individual Quick Freezing (IQF) technology to rapidly freeze fruits through the maximum ice crystal formation zone in a very short time, forming individually separated frozen particles.

Main Equipment:

IQF Freezers (e.g., Fluidized Bed Freezers, Tunnel Freezers).

Major Problems:

Insufficient freezing speed leading to large ice crystals, product clumping, high energy consumption, high equipment maintenance costs.

Process 7. Metal Detection & Quality Control

Key Processes:

Conducting metal foreign object detection on packaged products and performing sample inspections to ensure compliance with quality and safety standards.

Main Equipment:

Metal Detectors, X-ray Foreign Object Detectors, Laboratory Testing Equipment.

Major Problems:

Insufficient detection sensitivity, high false positive rate, human error in quality inspection.

Process 8. Sorting & Packaging

Key Processes:

Re-sorting frozen fruits to remove unqualified products, then weighing, measuring, and packaging them into retail or industrial products.

Main Equipment:

Vibrating Screens, Automatic Weighing Machines, Packaging Machines, Sealing Machines.

Major Problems:

Packaging damage, inaccurate weighing, packaging materials not meeting standards.

Process 9. Cold Storage & Transportation

Key Processes:

Storing packaged frozen fruits in low-temperature cold storage and transporting them to sales terminals via cold chain logistics, ensuring the product remains frozen throughout.

Main Equipment:

Cold Storage Facilities, Refrigerated Trucks, Temperature Monitoring Systems.

Major Problems:

Cold chain breaks leading to product thawing and spoilage, temperature fluctuations during storage, high energy consumption.

7. How V-Trust Controls Agricultural Products Quality

V-Trust delivers comprehensive agricultural products inspection services, ensuring consistent product quality and regulatory compliance. Our quality control solutions cover all stages of agricultural products, including Sample Checks, Production Monitoring, During Production Inspection, Pre-Shipment Inspection, and Container Loading Supervision, reducing the risk of product failures and costly recalls.

Sample Check

Our experts evaluate agricultural product samples for visual quality, freshness, and adherence to grade standards. For example, we check for consistent sizing, absence of pests, and proper moisture content in grains, helping to confirm the supplier's initial quality claims.

Production Monitoring

During harvesting or processing, our inspectors are on-site to monitor critical steps such as sorting, cleaning, and initial packaging. For instance, we ensure that fresh produce is handled gently to prevent bruising and that sorting lines effectively remove defective items.

During Production Inspection

When a significant portion of the agricultural products are being prepared for shipment, we conduct an inspection to identify issues like inconsistent grading, improper storage conditions, or early signs of spoilage. For example, we check temperature logs for refrigerated goods and verify that packaging materials are suitable.

Pre-Shipment Inspection

Before loading, a thorough inspection is performed to verify the final quality, quantity, and packaging of agricultural products. This includes checking for pest infestation, confirming accurate weight and count, and ensuring all labeling (e.g., origin, grade, expiry) is correct and compliant.

Container Loading Supervision

We supervise the loading process to ensure agricultural products are handled carefully, stacked correctly, and that the container environment (e.g., temperature, ventilation) is appropriate. For instance, we confirm proper dunnage for fragile items and verify that refrigerated containers maintain the set temperature.
