LEESOLU Automatic Small Fresh Fruit Weighing & Boxing Line | Standardized Packaging Technology & Industry Applications

In the fresh retail sector, boxed small fresh fruits are core best-selling products across supermarkets, grocery retailers, fresh e-commerce platforms and community group-buying channels. Fruits such as cherries, blueberries, cherry tomatoes, plums, apricots, kumquats and dates maintain steady year-round demand for boxed supply, supported by mature cold chain storage systems. As seasonal small fruits hit the market in concentrated periods, packaging pressure continues to rise, and the shortcomings of traditional manual packaging have become increasingly prominent.

Targeting practical pain points in weighing, boxing and sealing of small fresh fruits, the LEESOLU automatic small fruit weighing and boxing production line is tailored for standardized box packaging of multi-category, multi-specification small fruits, effectively solving various industry problems of manual packaging. Combined with core equipment parameters and field application cases, this article comprehensively analyzes industry challenges, equipment structure, category compatibility and core performance advantages of small fresh fruit packaging.

Three Core Pain Points of Manual Small Fruit Packaging

Small fresh fruits like blueberries, cherry tomatoes, cherries and longans are generally compact in size with delicate peels, making them highly prone to bruising and damage. For fresh produce processors, traditional fully manual sorting, weighing and boxing can no longer keep up with large-scale, standardized production rhythms. The most prominent industry problems are concentrated in three aspects:

1. Large Weighing Error & Low Standardization

Manual packaging relies on simple electronic scales. Affected by operation differences and worker fatigue, weight deviation per box is significant, often leading to underweight or overweight issues. This not only fails to meet the standardized supply requirements of supermarkets, but also causes fruit waste and increased loss rates.

2. High Bruising Loss & Unstable Product Quality

Small fresh fruits have thin peels and crisp pulp. They are highly vulnerable to bruising and squeezing during manual grasping, pouring and boxing, resulting in damaged fruits and poor appearance. This directly reduces the marketable rate of fresh fruits and drives up loss costs in fresh produce processing.

3. Low Production Efficiency & Inability to Handle Bulk Orders

Seasonal fresh fruits have concentrated launch windows and large short-term shipment volumes. Manual packaging has limited capacity and cannot support large-batch continuous production orders. Meanwhile, inconsistent finished product specifications from manual packaging make it difficult to match the bulk, standardized boxed supply needs of supermarkets.

Technical Principle of LEESOLU Automatic Weighing & Boxing Line

The LEESOLU automatic small fruit weighing and boxing production line is a standardized packaging system built exclusively for various small fresh fruits, completing the full workflow of weighing, boxing and lid pressing in one stop.

The equipment adopts a modular design: an automatic box feeding structure can be added according to production needs, and it can be connected with downstream equipment such as labeling, coding, cartoning and palletizing systems to realize fully automatic continuous production. It supports flexible adjustment of packaging specifications, adapting to boxed processing of small fresh fruits of different sizes and weights with strong compatibility.

The entire line adopts a linear filling mode for small fruits, replacing manual operation with mechanized conveying, precise weighing and automatic drop filling. It operates stably and continuously throughout the process, effectively solving the industry pain points of manual packaging: large weighing error, high fruit loss and low efficiency. It is highly suitable for mass production of plastic-boxed fresh fruits for supermarkets.

Equipment Sub-Systems & Full Category Compatibility

There is a wide variety of small fresh fruits on the market, with significant differences in texture and size. A single packaging device can hardly cover all categories. For this reason, the LEESOLU automatic small fruit weighing and boxing production line is subdivided into a general linear filling system and multiple dedicated customized packaging lines, matched to the processing characteristics of different fruits and covering the boxed production needs of seasonal small fruits all year round.

1. General-Purpose Small Fruit Linear Filling System

This is a universal packaging system compatible with most small fresh fruits such as apricots, cherries, cherry tomatoes, plums, kumquats and winter jujubes, completing the basic processes of weighing, boxing and lid pressing.

It can be equipped with an automatic box feeding device, and connected with downstream labeling, coding, cartoning and palletizing equipment to realize fully automatic production. Packaging specifications can be adjusted on demand to adapt to small fruits of different sizes and weights, meeting conventional boxed production needs for supermarkets.

2. Dedicated Weighing & Boxing System for Cherry Tomatoes

This system is specially designed for large-batch cherry tomato packaging, with a complete standardized production flow: fresh fruits are fed smoothly via horizontal conveying equipment, lifted into a 24-head multihead weigher (12×2 AB dual-weigher structure) for quantitative weighing, then automatically drop-filled and sealed for stable continuous production.

Packaging specifications can be flexibly adjusted. Besides cherry tomatoes, it is also compatible with similar small fruits such as kumquats, winter jujubes and plums, meeting multi-category production needs.
