Compact 4-Tray Freeze Dryer for Home Business

Overview of 4-Layer Home Pro Freeze Dryer

Basic Working Logic

The 4-layer home pro freeze dryer removes moisture from solid and liquid materials through sublimation under low-temperature and vacuum conditions. This process retains the original shape, color and nutritional composition of materials to a large extent. The equipment integrates pre-freezing, vacuum drying and defrosting functions, and supports regular program updates to adapt to varied processing needs. Its operating noise level fits small indoor processing spaces without extra sound insulation measures.

Suitable Commercial User Groups

This freeze dryer series is designed for small and medium commercial users, including specialty food stores, pet food producers, catering operators, and emergency supply procurement teams. Four models with different processing capacities are available, matching production scales from small batch trial production to regular batch processing.

Core Components of Freeze Dryer Equipment

Vacuum Pump System

Each unit is matched with a dedicated vacuum pump, which uses 46# vacuum pump oil. The pump operates at 2100 rpm rated rotational speed and 3A rated current under 220V power supply, delivering stable vacuum extraction performance during the drying cycle.

304 Stainless Steel Trays

The equipment trays are made of 304 stainless steel, manufactured with one-piece die-casting process. There are no welding gaps on the tray surface, and the corners are polished with smooth edges. The 4-layer configuration comes with 45mm shelf spacing, leaving sufficient space for materials of different thicknesses.

Touch Operation Display

The equipment is fitted with a touch operation display screen, with preset automatic programs for common materials. Users without prior freeze-drying experience can complete operations through the built-in programs. The display also supports manual adjustment of freezing temperature, drying temperature and extra processing time, to adapt to different material characteristics.

Commercial Applications of Freeze Dryers

This series of freeze dryers adapts to multiple commercial scenarios. For specialty food retail, operators can produce freeze-dried fruits, vegetables, candies and meat products for sale, with processing costs lower than outsourced procurement. For food storage demands, freeze-dried products can be stored for long periods without spoilage, suitable for catering businesses and emergency reserve departments. For pet food production, the equipment can process meat, vegetables and mixed ingredients into freeze-dried pet food with high digestibility. It can also process liquids, herbs, coffee and other materials to meet diversified commercial processing needs.

Freeze Dryer Model Selection Reference

The four models correspond to different production demands. The DFD-04 model with 4 trays fits small batch trial production and small retail stores. The DFD-06 and DFD-10 models are suitable for regular small-scale production for specialty food shops and pet food brands. The DFD-20 model with larger drying area adapts to medium-scale commercial production lines. Users can select the appropriate model based on daily processing volume and available site space.
