PP Bread Compartment Tray for Industrial Frozen Food Production – 30 Cavity

Product Overview

The BL-30 PP Bread Compartment Tray is designed for industrial bread and bakery production lines, where consistent portion control, stable handling, and reliable freezing performance are required.
Featuring 30 individual round cavities, this tray supports standardized placement of bread and dough-based products before freezing, helping food factories improve efficiency and reduce product damage.

Manufactured from food-grade polypropylene (PP), the BL-30 tray is suitable for pre-formed bread products that require separation during processing, freezing, and internal circulation.
Its structure is optimized for heavier products compared with pastry or mochi trays, providing stronger support and better load-bearing performance.

Cavity Design for Heavier Dough-Based Products

Bread products typically have:

• Higher weight per unit

• Denser structure

• Greater downward pressure during freezing

The BL-30 tray addresses these characteristics through:

• Reinforced cavity structure

• Balanced cavity depth

• Strong tray base to reduce bending

This design helps maintain product shape and consistency throughout freezing and handling processes.

Food-Grade PP Material Advantage

The BL-30 tray is produced using food-grade polypropylene (PP), offering:

• Safe direct food contact

• Resistance to oils, moisture, and flour residue

• Stable mechanical strength

• Easy cleaning and handling in factory environments

PP material is widely used in industrial bakery applications due to its durability and low-temperature stability.

---

Freezer-Safe Performance Down to -45℃

This PP bread tray is engineered for industrial freezing conditions, with reliable performance down to -45℃.

During blast freezing and frozen storage, the tray:

• Maintains cavity shape

• Does not crack or become brittle

• Supports repeated handling of frozen products

This makes it suitable for pre-freezing, frozen storage, and post-freeze transportation within food factories.

---

Product Separation & Shape Protection

Direct contact between bread products during freezing can lead to:

• Surface damage

• Deformation

• Difficult separation after freezing

The individual cavity design of the BL-30 tray ensures:

• Clear separation between products

• Reduced risk of sticking

• Improved consistency in final product appearance

---

Compatibility with Automated Production Lines

The BL-30 tray is designed to integrate smoothly into:

• Automated depositing systems

• Conveyor-based freezing lines

• Manual or semi-automated loading processes

Its consistent dimensions and stable structure support reliable operation in high-volume production environments.

---

Durability & Reusability in Industrial Environments

Designed for factory use, this PP compartment bread tray offers:

• Strong load-bearing capacity

• Resistance to bending during stacking

• Long service life for internal circulation

The tray is suitable for repeated use in industrial bakery and frozen food production facilities.

---

Customization Options

Although BL-30 is a standard model, customization is available based on production needs, including:

• Cavity diameter adjustment

• Different cavity counts

• Tray thickness optimization

• Custom tray dimensions

• Color or identification marking

Customization ensures the tray fits specific bread size, weight, and freezing behavior.

---

Quality Control & Manufacturing Capability

Each BL-30 tray is manufactured under controlled thermoforming conditions to ensure:

• Consistent cavity geometry

• Uniform wall thickness

• Smooth, food-safe edges

Strict quality control helps maintain stable performance across large production volumes.

FAQ

Q1: Why is PP material preferred for industrial bread freezing trays instead of PET or PS?

PP (Polypropylene) offers superior low-temperature resistance and mechanical stability, making it more suitable for industrial freezing applications.
Unlike PET or PS, PP remains tough and flexible at temperatures as low as -45℃, reducing the risk of cracking or brittleness during blast freezing.

In addition, PP has better resistance to oils and moisture commonly found in bread and dough products, ensuring stable performance throughout repeated production cycles.

Q2: How does the 30-cavity design improve freezing consistency for bread products?

The 30-cavity layout ensures uniform spacing and controlled product placement, allowing cold air to circulate evenly around each bread unit during freezing.

This controlled separation helps:

• Reduce uneven freezing

• Prevent surface deformation

• Maintain consistent size and appearance after thawing

For bread production lines focused on quality consistency, cavity separation plays a critical role in process stability.

Q3: Is this tray suitable for automated or semi-automated production lines?

Absolutely. The BL-30 tray is dimensionally consistent and engineered for compatibility with:

• Automated depositing systems

• Conveyor-based freezing tunnels

• Robotic or manual loading processes

Stable tray geometry ensures smooth movement along production lines without misalignment or jamming.

Q4: Can cavity diameter or depth be customized for different bread sizes?

Yes. DASHAN supports custom cavity diameter, depth, and tray dimensions based on your specific bread size, dough behavior, and freezing requirements.

Custom designs are commonly requested when factories introduce new SKUs or adjust portion weight for different markets.

Q5: How does this tray perform in long-term industrial use?

Designed for factory circulation, the BL-30 tray offers:

• High impact resistance

• Stable shape retention at low temperatures

• Consistent performance under repeated handling

This makes it suitable for long-term use in high-volume production environments.

Q6: Is the tray compliant with food contact safety standards for export markets?

Yes. The tray is manufactured using food-grade PP material and complies with major international food-contact safety requirements.
It is suitable for export-oriented food processing operations serving multiple markets.

Q7: What should be considered when choosing between 30-cavity and higher-cavity trays?

Tray selection depends on:

• Individual product weight

• Product diameter and height

• Freezing time requirements

• Line capacity and handling method

Heavier bread products typically benefit from fewer cavities with stronger support, making the 30-cavity configuration a practical choice for bread production.

Q8: Can samples be tested before bulk production?

Yes. Samples are available for testing on your production line to verify:

• Fit with existing equipment

• Product separation performance

• Freezing behavior and handling efficiency

This helps reduce risk before full-scale adoption.
