Food drying techniques for heat pump dryers & dehydrators
Airtek (Airtek Energy Systems Limited) is a Guangzhou export manufacturer of heat pump food dryers and industrial dehydrators. This hub collects practical food drying technique guides—temperature and process tips by material—so you can compare approaches before requesting a process proposal.
Pick a category below (fruit, vegetables, meat, seafood, herbs & spices, and more). Guides are conversation aids for commercial batches; exact recipes still follow your wet infeed, target moisture, and chamber design. Browse machines on Drying Solutions or share your material via Contact Us.

Food drying technique FAQ
What is this Food Drying Technique hub for?
It is Airtek’s index of material-specific drying technique guides (fruit, vegetables, meat, seafood, herbs & spices, and other categories). Use it to find temperature and process tips that pair with heat pump food dryers and dehydrators—then request a quote with your wet infeed and target moisture.
Who is Airtek?
Airtek (Airtek Energy Systems Limited) designs and builds heat pump food dryers and industrial dehydrators in Guangzhou for export plants. See the About Airtek page for manufacturer positioning and contact paths.
How do I get a process proposal or quote?
Open Contact Us and submit a short RFQ, or Chat on WhatsApp. Share material, batch size, and target moisture. Sales typically replies Monday–Saturday, 08:00–21:00 China time.
Are the technique pages recipe guarantees?
No. Guides are conversation aids based on common commercial practice. Exact programs depend on product form, loading density, chamber airflow, and your quality targets. Airtek engineers validate settings against your sample or RFQ data.
Why use a heat pump dryer instead of sun drying or electric/gas heat?
Heat pump dryers recover latent heat while dehumidifying, so chambers stay in a controlled low-to-mid temperature band with less weather risk than sun drying and usually lower kWh than straight electric resistance heat for the same moisture removal. Closed or semi-closed airflow also helps hygiene and batch consistency for export food plants.
What temperature range do heat pump food dryers typically use?
Most food and herb loads run roughly in the mid-30s to about 70 °C air temperature, tuned to the product’s heat sensitivity and target water activity. High-sugar fruit, leafy herbs, and seafood often sit cooler than hard root vegetables or wood-adjacent loads. Always confirm with a sample run—hub pages list starting points, not fixed recipes.
How do I choose between a cabinet dryer and a multi-trolley (open-loop) solution?
Cabinet units suit R&D, small commercial batches, and frequent product changeovers. Multi-trolley open-loop lines suit larger daily wet infeed with carts and trays moving as a system. Share daily wet kg, piece size, and target moisture on Contact Us or Drying Solutions so we can map capacity without oversizing.
How long does a drying cycle take?
Cycle time depends on starting moisture, piece thickness, tray loading, airflow, and final moisture—not on the machine name alone. Thin herb leaves may finish in a few hours; dense fruit slabs or seafood can need much longer. Send wet infeed %, target %, and a photo of the cut size for a realistic hour estimate.
Can one dryer handle many materials (fruit, herbs, seafood, etc.)?
Yes, with recipe changes, tray density control, and sometimes different trays or liners. Plants that switch SKUs often keep a cabinet for trials and a trolley line for volume SKUs. Cross-contamination and allergen rules still apply—plan cleaning between animal and plant runs.
What information should I prepare before asking for a quote?
List: product name and form (slice, whole, paste), daily or batch wet weight, starting and target moisture (or water activity), preferred power (e.g. 220V single-phase or 380V), site constraints, and destination country. Photos of current drying or rejected lots help. Optional: desired FOB timeline. We reply with a process proposal and machine shortlist—no need for a purchase commitment to start the conversation.
