B: China Quality Management System certification

APPLICATION

Suitable for freeze-drying processing of various materials, including:

BATCH MATERIAL PROCESSING CAPACITY MODEL BLK-FD-40

Based on a tray area of 40 m² and a loading height of 35mm, the per-chamber material processing capacity of BLK-FD-40 varies by material density: (Adjust according to material density)

FOOD CATEGORY	SOLUTION CATEGORY	FRUITS & VEGETABLES
600KG-800KG	400KG-600KG	300KG-400KG

INTEGRATED FREEZEDRYER WITH FLEXIBLE DIMENSION DESIGN FOR EASY WORKSHOP LAYOUT

The entire unit is fully integrated; materials can automatically complete freezing and drying processes within the freeze dryer.

Pre-engineered product combination dimensions minimize required floor space.

Length, width and height can be customized

Once the unit is assembled, on-site connection of water and electricity is all that's needed to put it into operation.

MORE SUITABLE SQUARE CHAMBER DESIGN FOR MEDIUM & SMALL-SCALE EQUIPMENT

With the same freeze-drying area and radiant panels of identical height and width specifications, a square chamber offers higher space utilization efficiency

Compared to circular chambers, the square chamber requires a smaller footprint for the same material loading capacity, enabling more flexible workshop layout;

The square chamber pairs better with material radiant panels and trays, maximizing the chamber's space utilization;

During freeze-drying, air flow and temperature distribution in the square chamber are more stable than in circular ones, ensuring consistent product drying quality;

For the same loading capacity, the square chamber requires less refrigeration and vacuum pump power than circular ones, resulting in more energy-efficient overall operation;

BOLAlKE has validated the square chamber as a reliable solution for medium-small scale production through global client production practices.

BOLAIKE'S UNIQUE DOUBLE-LAYER RADIANTPANEL DESIGN FOR SUPERIOR COOLING & HEATING EFFICIENCY

Equipped with internal double-layer radiant panels and dual-layer parallel circuits (upper layer: cooling circuit; lower layer: heating circuit).

Meanwhile, waste heat from the sublimation/heating stage can be recovered and recycled for material drying, reducing additional electric/steam heating. (Patent Nos.: CN209030727U [Radiant Panel]; CN204392676U [Double Radiant Panel])

BOLAIKE'S HIGH-EFFICIENCY ENERGY-SAVING TO REDUCE OPERATING COSTS

ENERGY-SAVING PERFORMANCE IS OUTSTANDING

20%-40%

Energy consumption reduced by 20%-40%

15%-25%

Single-batch cycle shortened by 15%-25%

PATENT NO.CN205784249U

INTEGRATED ENERGY STRUCTURE

Traditionally, cold storage and freeze-drying chambers require duplicate energy systems. Borui's integrated design allows cooling and drying processes to share a single refrigeration circuit, reducing system losses.

ENERGY RECYCLING SYSTEM

Cold recovery (STANDARD CONFIGURATION)

(PATENT NO.:CN206047043U)

Traditional designs use cold energy once then discharge it, keeping compressors in a continuous high-load state. BOLAIKE recycles cold energy from refrigeration system to pre-cool the next refrigeration system, reducing 20%-30% overall compressor load for energy-saving.

ENERGY RECYCLING SYSTEM

Heat recovery (CUSTOMIZATION REQUIRED)

(Patent No.: CN119468635B)

In freeze-drying, excess heat from the sublimation/heating phase is typically discharged. Bolaike recycles this heat (or steam heat) for material drying, reducing energy consumption.(Patent Nos.:CN209030727U & CN204392676U) When material heating temperature is≤35°C: 99% energy consumption saved;

When the required heating temperature of materials is below 80°C, ~10% of energy consumption can be saved (waste heat-enhanced large-scale vacuum freeze-drying system.

PATENTNO.: CN209612254U

HEAT PUMP & ECONOMIZER SYSTEM

This system increases the compressor's COP (Coefficient Of Performance) to 4.8-5.9, improving energy efficiency by 5-6 times compared to traditional freeze-drying equipment.
