One : How air source heat pump dryer come 

Drying is one essential processing step in Industrial and agricultural production . With the improvement of people's life quality, the environmental awareness is growing enhanced.Eeven with the reserves depletion of non-renewable energy sources (such as natural gas, coal, oil) , Recently yeears ,original fuel, coal, high energy consumption, high pollution drying equipment severely limited or even banned,thus an alternative energy saving and eco-friendly drying equipment is a impending , in this conditions , heat pump drying equipment came into being.

Two : Heat pump dryer history

Since the beginning of the 1960s, developed countries such as UK, Japan, France, Germany, Italy, United States etc has begin to develop heat pump drying technology. China introduced this technology in1990s, the first and most widely used field is wood drying. Because of the heat pump drying temperature is moderate and very similar to natural drying, in recent years it was gradually   used in food and agricultural drying, obtained the outstanding economic benefits, including increased drying product added value.

With the governmental advocation of energy conservation and environmental protection as well as vary environmental protection policies implementation, which greatly promote the development of heat pump drying technology, heat pump drying range became diversified, expanded from the early wood drying to meat products, aquatic products, wood, herbs, fruit, sausage, incense, stainless steel, tea drying applications, ceramics, rubber tires, insulation materials, corn seedlings, flour, noodles, and other industries, has accumulated a wealth of valuable experience.

Three : Heat pump is one system which can convert low potential heat source (natual lower temp. air ,water ,geothermal or other low-potential heat inside soil et ) to high potential heat source by working. There are air source, water source and geothermal source according to heat source.

Heat pump is one system which can convert low potential heat source (natual lower temp. air ,water ,geothermal or other low-potential heat inside soil et ) to high potential heat source by working. There are air source, water source and geothermal source according to heat source.

High temp.air source heat pump dryer is based inverse cano principle,compressor change the refrigerant mode from gas to liquid and inversel inside closed loop. Evaporator continue absorbing heat from air ,and condenser continue sending heat into drying room.Air temperature keeping increased inside drying room, water inside drying material keeping absorbed ,and discharged outside drying room,thus drying material become continuous drying.The electricity consumed during this process just keep refrigerant cycling,therefore little energy output obtain more energy ,then enegy saved.

Four: Cost comparision between heat pump dryer and other type of dryers.

1. High efficiency energy saving, lower running cost.

 

Name	Norminal heat value	Heat efficiency	Real heat value	Heat consumed
Electric dryer	860Kcal/Kwh	95%	817 Kcal/Kwh	86000Kcal
Coal boiler dryer	7000 Kcal/Kwh	25%	1750 Kcal/kg	86000Kcal
Fuel boiler dryer	30000Kcal/kg	80%	8240Kcal/kg	86000Kcal
Heat pump dryer	860 Kcal/Kwh	300%	2580 Kcal/Kwh	86000Kcal
Name	COP	Real nergy consumed	Energy cost	Runig cost
Electric dryer	95%	105Kwh	RMB0.8/  /Kwh	RMB84.0
Coal boiler dryer	25%	49Kg	RMB1.0/Kg	RMB49.0
Fuel boiler dryer	80%	10.4Kg	RMB5.3/Kg	RMB55.1
Heat pump dryer	300%	33.3Kwh	RMB0.8/ Kwh	RMB32.6

 

From the above data, we can find that the runing cost of heat pump dryer is only 30% of electic dryer ,40% of fuel boier dryer,60% of coal boiler dryer, moreover heat pump dryer don’t consume any fuel, no transportation cost and storage cost, significant economy advantage. 

2. No pollution to environment 

Heat pump dryer  only transfer vast heat to drying room during drying process, the consumed energy is used for tranfering heat, no need consume other fuel ,so there is no waste produced therefore no any pollution to environment.

3.  Good drying effect

Heat pump drying is automatically controlled by intelligent controlling system ,can automatically adjust heat pump working according set mode,fast temperature increasing,average temperature inside drying room,very tiny temperature difference ,thus avoid the human factor effect to drying material quality during drying process. 

4.  Heat pump drying technology prospect

Material drying is long and vast energy consuming process,partal drying process will effect the color, nutrient,taste , texture and tissue. Heat pump drying technology has the advantage of lower ernegy sonsuming, no evironment pollution ,good drying effect, scale operation. It has unshakable advantage of decreasing energy consuming and increasing drying material quality, now is on the way of increasing drying temperature,developing new type heat pump dryer and etc, new high temperature, low energy consuming heat pump drying technology will lead to a revolution in drying industry.
