Heat Pump Food Dryer (HPD0300)

Overview

Engineered for low‑temperature drying (30–75°C) with controlled relative humidity below 25%, the HPD Series preserves color, aroma, and nutrients while cutting energy use. Ideal for fruits, vegetables, herbs, spices, flowers, and other temperature‑sensitive products across food, agriculture, nutraceuticals, and more.

How it Works

Using reverse-refrigeration (heat pump) technology, the system adds latent and sensible heat to drive moisture out while a dehumidifier removes vapor to maintain a dry chamber. This closed-cycle approach achieves fast, uniform dehydration without high heat.

Key Features

• Wide control range: 30–75°C; RH maintained below ~25%
• Energy‑efficient heat pump with integrated dehumidification
• Tray‑trolley chamber design for easy loading and uniform airflow
• PLC/HMI control and recipe‑based cycle management (configurable)
• Scalable models from small pilot to multi‑ton raw‑material loading
• Clean, all‑electric operation; no combustion by‑products
• Optional remote/mobile monitoring and process data logging

FAQs

Q: What temperature and humidity ranges can the HPD control?

A: Typical setpoints are 30–75°C with relative humidity controlled below ~25%, depending on product and model.

Q: How do I size a dryer?

A: Start from daily raw‑material input and desired final moisture. Use the model tables above as a guide and request a tailored capacity check.

Q: Is it suitable for organic products?

A: Yes. The closed, all‑electric process avoids combustion by‑products, supporting clean‑label requirements.
