Home Freeze Dryer

Product Overview

 

The Industrial Series is an engineered-to-order commercial freeze dryer built for small-scale food processors, pet food manufacturers, and botanical extraction laboratories. Moving away from modified domestic appliance architecture, this system integrates heavy-gauge SUS304 stainless steel chambers, industrial hermetic refrigeration compressors, and PLC-based automated process control. It bridges the gap between laboratory pilot units and massive industrial tunnels, delivering repeatable batch processing with precise sublimation control.

Working Principle

 

Freeze drying (lyophilization) is executed through three distinct physical stages within a hermetically sealed vacuum chamber:


Freezing Stage: Product is loaded onto heated shelves and cooled to -40°C to -50°C, ensuring complete solidification of free water within the cellular matrix.


Primary Drying (Sublimation): A deep vacuum (< 15 Pa) is pulled inside the chamber. Controlled thermal energy is transferred through the shelves, causing ice crystals to sublime directly into vapor without a liquid phase transition, preserving 98% of structural integrity and nutritional profile.


Secondary Drying (Desorption): Chamber vacuum is deepened and shelf temperature is elevated up to +65°C to desorb bound moisture, driving final residual moisture content down to 1% - 3%.

 

Key Features

 

Dual-Stage Refrigeration Circuit:

Employs industrial single-stage or cascade systems powered by Danfoss/Secop compressors using R404A/R507 refrigerants, achieving condenser core temperatures down to -50°C (optional -80°C for low eutectic points).

01

Aseptic Chamber Construction:

Interior vessel, condenser coils, and trays are fabricated from food-grade SUS304 (optional SUS316L) with an electro-polished finish of Ra <= 0.4 um to inhibit microbial growth.

02

Eutectic Point Monitoring:

Optional thermocouple probes track product core temperature in real-time to prevent melt-back or structural collapse during primary drying.

03

Hot-Gas Defrosting:

Integrated hot-gas bypass clears frost accumulation from internal condenser coils within 15 minutes, minimizing turnaround downtime between batches.

04

Industrial Automation Architecture:

Siemens/Delta PLC paired with a 7-inch industrial HMI panel runs programmable multi-stage recipes (up to 36 segments per cycle) with data logging via USB/Ethernet.

Food Vacuum Freeze Dryer

 

Configuration & Components

Vacuum Pump Assembly: Two-stage rotary vane pump (Leybold or Ulvac standard, equipped with an oil-mist filter; oil-free dry scroll pump available as an alternative).


Refrigeration Components: Hermetic reciprocating compressors, brazed plate heat exchangers, and electronic expansion valves for precise superheat regulation.


Shelving & Heat Transfer: Hollow-plate aluminum shelves circulated with heat-transfer silicone oil, maintaining surface temperature uniformity within +/- 1°C.


Chamber Sealing: FDA-compliant food-grade silicone door gasket featuring a hollow pneumatic expansion design for positive locking under deep vacuum.

Applications

 

 

Specialty Food Production:

Single-origin fruits, specialty mushrooms, prepared meal components, and soluble coffee granules.

 

Pet Treat Manufacturing:

Raw meat diets, high-fat organ meats (liver, heart), and whole-prey formulations retaining native palatability and heat-sensitive nutrients.

 

Botanical & Nutraceutical Processing:

Heat-sensitive herbal extracts, bacterial cultures, and enzyme preservation requiring strict low-temperature thresholds.

 

 

 

Model Selection & Configuration Options

Determining the correct model requires calculating raw material water mass and operational batch frequency:


Sizing Formula: Calculate the total water weight in your wet input material per batch. Ensure the selected model's 24-hour ice condenser capacity exceeds the total water mass removed per cycle, maintaining a minimum 20% safety buffer.


Optional Engineering Upgrades:
• Oil-Free Dry Scroll Vacuum Pump: Removes hydrocarbon back-streaming for cleanroom and pharmaceutical-grade environments.
• Clean-in-Place (CIP) System: Integrated spray balls and sanitary piping for automated internal washdown.
• PC SCADA Integration: Centralized monitoring software for multi-unit production facilities.

FAQ

 

 

Q: What are the exact electrical specifications, and can these units run on standard residential circuits?

A: Model 10 operates on standard single-phase power (220V, 60Hz). Models 30 and 50 require 3-phase industrial power (208-480V). Verify facility circuit breaker capacity against the installed power rating (kW) in the specification table before installation.

Q: What is the operating difference between rotary vane oil pumps and dry scroll vacuum pumps?

A: Rotary vane oil pumps are standard, heavy-duty, and cost-effective, but require regular oil level checks and oil-mist filter maintenance. Dry scroll pumps are totally oil-free, preventing hydrocarbon vapor migration into the vacuum chamber, which is recommended for high-purity food or botanical processing.

Q: What is the typical duration of a complete freeze-drying cycle?

A: Cycle times range from 24 to 48 hours depending on product thickness, sugar/fat content, and total moisture load. High-sugar fruits or dense protein matrices require extended secondary drying phases compared to thin vegetable slices.

Q: What routine maintenance is necessary to maintain vacuum integrity?

A: Maintenance protocols include inspecting the door silicone gasket for particulate debris or deformation before every run, replacing vacuum pump oil every 500 operational hours, and checking refrigeration line pressure gauges bi-annually.

Q: What documentation is included with each shipment for import and validation?

A: Shipments include an English Operation & Maintenance Manual, electrical schematics, P&ID diagrams, PLC program logic maps, factory calibration certificates, and material test reports (MTRs) for customs clearance and facility validation.

Q: What is the standard warranty coverage and spare parts availability?

A: Equipment includes a 12-month international warranty covering core components (compressors, vacuum pumps, PLC controllers). Critical maintenance wear parts (gaskets, solenoid valves, oil filters) are stocked in regional distribution centers for dispatch within 48 hours.
