Why has the air hot air cycle drying equipment become so popular over the years?

2020-06-28 14:03:23 411

In recent years, a new type of dryer that uses less energy and caters to the needs of the environment has gradually come into the limelight, from skepticism, trial, improvement and enhancement to acceptance by most people.


It, is what our industry calls a heat pump dryer, also known as an air dryer.


The working principle of heat pump dryer is to use the principle of inverse cano, the refrigerant (mostly mixed refrigerant) is compressed by the compressor to become a high temperature and high pressure gas, the gas temperature can reach 100-110 ℃, the high temperature gas enters into the heat exchanger (condenser) through the pipeline (copper pipe), and then through the fan, the heat generated by the heat exchanger (condenser) is sent to the drying room to heat and dry the material, the moisture of the heated material in the drying room is evaporated, and then discharged to the drying room through the dehumidifier or dehumidifier, so as to achieve the purpose of drying.

Air energy hot air circulation drying equipment details.


Hot air circulation oven temperature uniformity is a very important performance, is also an important indicator to determine the quality of the oven. Oven in the temperature control stage, although the control instrument temperature is basically more stable, but the temperature of the various points inside the box is not the same, which may be This causes the material to be heated differently in different locations. This affects the rate of dewatering of the quality of the finished baked product.


How to control the same baking room in the hot air direction, so that the temperature of each point in the baking room tend to be consistent. First of all, in the size of the baking room is determined, the calculation of the air volume is very important, heat transfer efficiency is determined, then the hot air to the air pressure, wind speed It's closely related to the fan size and the size of the grill. Reasonable fan preparation, will be able to make the hot air flow in the baking room tend to be uniform.






Make hot air circulation oven more energy efficient is very important for the manufacturing enterprises, but also a key to reduce costs.


The heat pump Canino in the United Heat Division using the principle of heat pump, using a small amount of electrical energy to achieve the purpose of drying, energy saving than the traditional drying more than 20% -50%, revolutionary cost reduction, to a large extent, improve competitiveness.


Improve the energy efficiency of hot air circulation drying oven can be started from these angles: improve the hot air circulation drying oven entrance air temperature, reduce the temperature of the exhaust gas at the exit of drying equipment; do a good job of insulation of the drying system to reduce the drying process of various heat losses.


In addition, before the material enters the hot air circulation oven, the pre-dewatering treatment such as filtration, centrifugal separation or evaporation of the evaporator can increase the solid content of the material, so reduce the evaporation load of the oven, is also an effective way to save energy in drying equipment.

With the development of the industry, non-standard customization has more and more customer demand. More manufacturers need drying equipment to meet the special process requirements based on the products of this enterprise, non-standard custom equipment is particularly important.



Large drying processing centers and processing enterprises, why to once to the dryer enterprise exchange, the fundamental reason is to the details of the company's product processing process, and dryer enterprise equipment technology to match, so that the drying process is more intelligent and energy efficient, in terms of capacity, performance, energy saving can have more highlights.


At present, the domestic hot air circulation ovens have been upgraded many times, and many excellent suppliers have introduced oven equipment that has reached domestic and foreign Advanced Level. In the new market environment, only by continuously surpassing the same type of products can we further meet the market demand.
