Small Food Freeze Dryer

For businesses specializing in single-ingredient pet treats-such as freeze-dried beef liver, salmon cubes, or raw chicken breasts-mass-market consumer freeze dryers are too fragile, while giant industrial tunnels require too much upfront capital. The food-grade HFD-5S occupies the exact middle ground, handling a processing capacity of 4-6 kg per batch. Let's break down how this works when loading real meat proteins onto the line.

Raw meat contains roughly 70% to 75% water by weight. When you spread 5 kg of diced chicken breast across the 5 material trays (195*460mm ), you are placing approximately 1 kg of wet product on each level. The 40mm tray spacing becomes critical here: it gives you enough vertical clearance to slice meat into 20mm cubes without them touching the heating shelf above. This gap ensures that as the cold trap drops to -40°C, radiant heat transfers evenly through the bottom of the tray while allowing evaporated moisture a clear path to escape into the condenser.

Over a 24-hour cycle, the HFD-5S is rated to capture 4 kg of water. For a 5 kg batch of raw poultry, this means the machine will pull out roughly 3.5 to 3.7 kg of moisture, leaving you with approximately 1.3 to 1.5 kg of bone-dry, shelf-stable pet treats with a residual moisture level close to zero. Because the core vacuum pressure drops below 2 Pa, the cellular structure of the meat does not shrink or harden; it remains porous, allowing the end consumer (or their pets) to rehydrate the meat in warm water within minutes.

Sanitation compliance is another reason small-batch processors use this model. The vacuum chamber and shelving are made from solid 304 stainless steel. When switching a production run from raw white fish to beef heart, a simple washdown with food-safe sanitizer prevents odor carryover and eliminates cross-contamination risks. Running at under 60 decibels, the HFD-5S allows small boutique kitchens to run commercial-grade raw pet food operations without disrupting surrounding retail or office spaces.

Small Food Freeze Dryer is widely adopted in the pet food industry for high-end freeze-dried treats, in the botanical sector for preserving flowers and herbal extracts, and in laboratories for biological sample preparation.
