Material Dehydration/Drying

Heat Pump Drying Machine

Heat pump drying is a novel dehydration process in a wide variety of foods and snacks now. It is actually an upgrade of the traditional drying method. Heat pump dehydrator and dryer can widely used to dry variety of fruits such as mango, dates, lemon, strawberry, pineapple, plum, apricot, banana, fig, and most kinds of fruit material.

Working Principle

Using heat pump technology for pool heating

During drying, the air is closed circulation between the drying room and the heat pump dryer. The  mango dehydrator machine cools and dehumidifies the wet air in the drying room.

When the wet air flows through the evaporator of the heat pump, the internal low-pressure refrigerant absorbs the heat from the air and changes from liquid to gas. When the dehumidified cold air passes through the condenser, the internal high-pressure refrigerant releases heat due to condensation, and the external air is heated to hot air and goes back to the drying room to continue drying. The high-pressure refrigerating liquid flowing out of the condenser passes through the expansion valve and flows into the evaporator to continue the next cycle.

feature / advantage of heat pump fruit dehydrator and dryer

1.High efficiency and energy saving: More than 60% less store consumption than traditional electric heating and drying equipment, not affected by rainy weather;
2.Safety and environmental protection: Full power operation, no pollution to drying materials and external environment, greatly improve the working environment;
3.Automatic temperature control system: Adopt self-control thermostat device to ensure reasonable temperature and humidity required for drying. Simply operation without personnel on duty, save time and labor, meet all kinds of materials drying quality requirements;
4.Reasonable structure design: scientific planning, optimize investment costs, Easy installation and maintenance, smooth operation, easy to use.

  • 1. Determine the hottest temperature you want to heat your water up to.

    Ex.) A target temperature of 27℃

    This is your target temperature

  • 2. Find the average temperature of the coldest month of the year for the area you live in

    Ex.) If you live in area, the coldest average temperature during swim season may be 15℃

    15℃ is the average temperature

  • 3. Subtract the coldest average temperature from the target temperature

    Ex.) 27℃ (target temperature) – 15℃ (coldest average temperature) = 12℃

    12℃ is your temperature increase number

  • 4. Calculate the size of your pool/surface area

    Ex.) 5m x 10m = 50 sqm (Surface Area/Pool size)

    Use this formula to calculate your pool’s surface area: Width x Length = Surface Area

  • 5. Calculate the amount of heating power (BTUs) needed to heat your pool

    Ex.) 50 x 12 x 230 = 138,000 BTUs

    You already have all the numbers you need, so here’s the formula:

    Pool Surface Area x Temperature Increase x 230 = BTUs needed

    According to the above example, a heat pump size of at least 108,000 BTUs or more would be a good choice.
