How to Overcome Industry Pain Points with Custom-Built Solutions? Upper’s "Multi-Format Dried Tofu packaging Line" Delivers the Answer!

In food packaging machinery, "custom-built solutions" are far from simple. Many companies invest in tailored production lines only to face recurring challenges:

· Rigid Equipment: Off-the-shelf machines fail to handle unique product shapes or processes;

· Efficiency Bottlenecks: Issues like product stacking or defect removal cripple throughput;

· Hidden Safety Risks: Conventional materials/designs risk contamination and compliance failures.

· At Upper, true customization means technology solving pain points. Rooted in engineering excellence, we dive deep into your operations to transform challenges into high-efficiency solutions. Our success with the multi-format dried tofu automatic feeding and packaging line proves this approach.

Case Study: Conquering Customization Challenges in Dried Tofu Packaging

Client Goal: Automate feeding and packaging for four tofu variants, overcoming fragility, irregular shapes, and strict hygiene requirements.

Breakthrough Solutions by Upper:

1.Pain Point: Tofu Stacking → Line Jams & Downtime

·Root Cause: Soft tofu slabs easily stick and pile during conveyance, disrupting alignment.

·Upper’s Solution: Upward and downward conveying device

·Precision-engineered lift height/speed gently separates stacked slabs;

·Patented flow guides ensure single-file entry into next stage;

·Result: >95% reduction in stacking, seamless line flow.

2.Pain Point: Defective Slabs → High Labor Costs & Missed Defects

·Root Cause: Manual sorting of broken/irregular/discolored tofu is slow and error-prone.

·Upper’s Solution: Visual inspection equipment

·Custom optics + lighting capture surface/contour details;

·Deep-learning algorithms detect flaws (cracks, stains, deformities);

·High-speed pneumatic ejectors remove defects in milliseconds.

·Result: ≥99.5% defect detection, 70% lower labor costs.

3.Pain Point: Food Safety Compliance → Audit Risks

·Root Cause: Equipment surfaces must eliminate contamination risks.

·Upper’s Fix: End-to-End Food-Grade Design

·FDA-compliant PU/PVC conveyor belts (non-toxic, easy-clean);

·304 stainless steel frame + radiused/seamless joints (zero traps);

·Full material certification documentation support.

·Result: 100% food-contact compliance, effortless audits.

In addition, when preparing materials for packaging, they need to be packaged in a certain order.

·Solution: Automatic sorting distance adjustment unit

·Set up multiple conveyor belts to arrange materials in the specified order;

·Install multiple high-precision sensors above the device to adjust the spacing between materials;

· Result: The materials can be arranged and the spacing between them can be adjusted according to the actual situation, which facilitates packaging processing

Finally, the materials need to meet customer requirements for packaging -150 packs per minute.

·Upper solution: High speed pillow packaging machine

·Efficient and fast

Highly automated, with adjustable packaging speed.

The general packaging speed is between 30-200 packages per minute, and some materials can reach over 300 packages per minute. It can be adjusted according to different products and production needs to meet the production requirements of different scales.

·Strong adaptability

Diverse packaging materials and flexible packaging specifications.

Composite films made of various materials can be used; Such as heat sealable composite films (PE/PET, OPP/PE, OPP/CPP), food grade composite films, heat shrink films, etc.

Ability to adjust the parameters of packaging bags according to different product sizes and packaging requirements, achieving packaging of multiple specifications

·Result: Achieving the packaging speed requirements required by customers has reduced a significant amount of manpower and material resources for them.

Delivered Value: The Power of Precision Customization

·40% Higher Throughput: Consistently hits production targets;

·Lower TCO: Reduced labor and maintenance costs;

·Zero-Compromise Safety: Passed stringent food safety audits;

·Future-Ready Flexibility: Modular design accommodates product changes.
