Small freeze drying equipment – Compact Industrial Vacuum Lyophilizer

Product Overview

Small freeze drying equipment is designed for laboratory-scale, pilot production, or small-batch industrial applications. Manufactured by Shenyang Aerospace Xinyang Quick-Frozen Equipment Manufacturing Co., Ltd., these compact systems integrate high-efficiency vacuum technology, precise temperature control, and advanced automation to deliver premium-quality freeze-dried products even at a smaller scale.

Freeze drying, or lyophilization, removes moisture from frozen materials by sublimation under vacuum, allowing products to retain their natural shape, color, texture, aroma, and nutrients. Small Freeze Dryers are perfect for R&D laboratories, small food processors, herbal and nutritional product manufacturers testing new formulations or producing limited quantities.

Key Features

• Compact design: Saves floor space while maintaining high performance

• Radiant heating plates or shelf heating system: Ensures uniform drying across trays

• Integrated vacuum system: Provides stable and precise low-pressure conditions for sublimation

• Cold trap/condenser: Captures water vapor efficiently to maintain vacuum and energy efficiency

• Automated control system: PLC or microcontroller-based operation for temperature, pressure, and cycle management

• Tray capacity: Suitable for small-scale batch production, with easy loading and unloading

Small Freeze Dryers offer flexibility, reliability, and easy maintenance, making them ideal for small businesses, pilot plants, and quality testing environments.

Applications

Small Freeze-drying equipment is widely used for:

• Food industry: Freeze-dried fruits (strawberries, blueberries, apples), vegetables (peas, carrots, mushrooms)

• Herbal and medicinal products: Ginseng, goji berries, plant extracts

• Nutraceuticals and dietary supplements: Protein powders, vitamins, functional foods

• Pet food and snacks: Limited production batches for premium products

• Laboratory and research purposes: R&D of new products and process optimization

Products retain excellent rehydration, flavor, and nutrient content, making them suitable for premium retail, small-scale export, or experimental production.

Operating Instructions

1. Preparation of Raw Materials
   Clean, cut, and pre-treat products according to specifications.

2. Tray Loading and Freezing
   Place products evenly on trays and freeze at –25°C or below in a cold storage or freezing tunnel.

3. Vacuum Freeze Drying
   Load frozen trays into the drying chamber. The vacuum system reduces pressure, while the heating system sublimates ice into vapor. The cold trap captures water vapor to maintain vacuum.

4. Completion and Packaging
   Introduce sterile air or nitrogen to normalize chamber pressure. Remove dried products, inspect, and package. Clean trays for the next cycle.

Advantages

• Compact and Space-Saving: Ideal for laboratories, pilot plants, or small-batch production

• Energy Efficient: Advanced heating and condensation system minimizes energy consumption

• Uniform Drying: Consistent product quality due to precise heat and vacuum control

• Preserves Nutrients: Maintains color, flavor, structure, and nutrition

• Easy Operation: Automated controls and minimal maintenance required

• Versatile: Handles fruits, vegetables, herbs, supplements, and other sensitive products

Conclusion

Small freeze-drying equipment offers a reliable, compact, and efficient solution for producers requiring pilot-scale or small-batch production. By combining precision vacuum control, uniform heating, and advanced automation, these systems deliver high-quality freeze-dried products with long shelf life, excellent rehydration, and nutrient preservation.

Ideal for food, herbal, nutraceutical, and laboratory applications, small freeze dryers provide the flexibility and performance needed to innovate and produce premium products for both domestic and international markets.
