What should the hot air circulating oven manufacturer improve?

At present, in the pharmaceutical, chemical, food and other industries, the use of hot air circulation ovens has become very common. With the rapid development of China's drying technology, the competition among oven equipment manufacturers has become increasingly fierce. How to improve market competitiveness has become a difficult problem for many small and medium-sized enterprises. From the customer's point of view, the author mainly explains the improvement of the current hot air circulation oven.

Pay attention to temperature uniformity

The average temperature of the hot air circulation oven is a performance that the customer values ​​very much, and is also an important indicator for judging the quality of the same oven. In the constant temperature stage, although the temperature of the control instrument is basically stable, the temperature at each point in the box is different, which may cause the samples in different positions to be heated differently.

Before production, the company should first thoroughly inspect the hot air circulation oven to eliminate the hazard.

Before the hot air circulation oven is turned on, turn the knob of the temperature protection switch clockwise to the limit position, and then start the machine according to the instructions specified in the manual; otherwise, it may cause the alarm to be turned on and the power supply is cut off. At this time, the power supply needs to be turned off, and the temperature protection is adjusted. Turn the switch on again.

If the temperature of the studio has not reached the temperature set by the meter after the power is turned on, the bell is turned off and turned off, then the adjustment value of the temperature protection switch is lower than the set temperature value of the meter. This also needs to turn off the hot air circulation oven power supply. , re-adjust the thermostat switch and turn it on again.

Improve energy efficiency

Making the hot air circulation oven more energy efficient is very important for the production company and a key to reducing costs. According to industry insiders, improving the energy efficiency of hot air circulation ovens can be achieved from these angles: increasing the inlet air temperature of the hot air circulation oven and lowering the exhaust gas temperature of the drying equipment; doing the insulation work of the drying system and reducing the various heat losses in the drying process. .

In addition, before the material enters the hot air circulation oven, pre-dewatering treatment such as filtration, centrifugal separation or evaporation of the evaporator can increase the solid content in the material, thereby reducing the evaporation load of the oven, and is also an effective method for energy saving of the drying equipment.

No cross contamination

According to industry insiders, cross-contamination must be prevented in hot-air circulating ovens and designs. Because of the double-door oven, one is set at 100,000 and one is at 100. For the sterility requirements such as pharmaceuticals, the environmental level is 100, so the whole process of oven sterilization and heat removal must be carried out under laminar flow protection.

Non-standard customization

With the development of the times, non-standard customization has increasingly become the demand of customers. Meeting the process requirements is the purpose of the equipment. At present, many oven manufacturers have been able to provide non-standard equipment that meets various process requirements.

There is an oven manufacturer to pass the material to be processed through a suitable cloth mechanism, such as a star-shaped cloth machine, a swing belt, a pulverizer or a granulator, distributed on the conveyor belt, and the conveyor belt passes through the passage of the same or two or three heating units. A heating unit is provided with an air heating and circulation system. Basically, each channel has the same or two or three drainage systems. When the conveyor belt passes, the hot air passes through the conveyor belt from top to bottom or from bottom to top. The material on the material so that the material can be evenly dried.

At present, the domestic hot air circulation oven has been upgraded many times, and the oven equipment introduced by many excellent suppliers has reached the advanced level at home and abroad. In general, the market prospects of China's oven equipment are still very impressive, but in the new competition, only by continuously surpassing the same type of products can we further meet market demand.


CONNECT compact poultry processing system is the lates designed system for small sacle and low investment users ,including the Full Automatic Porcessing Line and Poultry Conveyor Line ,with its simple installation, convinent operation, low investment, CONNECT compact Poultry Processing Equipment wins many clients from worldwide.


For many users to build one complete slaughterhouse, it takes long time to solve the fiancial, project approvement from local government, land and building required...,

normally involves big investment. But still have many users who don't have big investment for whole project, CONNECT slove this problem for most users, which is the Compact Poultry Processing Line equipment is lower investment , and working capacity can reach up to 500BPH.


The system compact birds hanging, stunning, killing, bleeding, scalding, de-feathering, eviscerating, and birds unloading into one.


The working process is first manual hanging the birds to conveyor line shackles --- stunning the birds--- manally killing--- bleeding-- pass into scalder--- de-feathering hair after pass through the plucker --- manually eviscerating --- unloading the birds from shackle at last.


The shape of system can be designed according to the client building shape and size.
