Promising pet food drying equipment

As we all know, Wenzhou used to be a famous "skin capital", famous for its leather bags, leather shoes and other categories all over the country. In recent years, with the government's increased emphasis on environmental protection, the leather business that pollutes the environment has been restricted, and the witty Wenzhou people have turned their attention to "dog chews" that also use sacks, cowhide, etc. as raw materials, which can not only improve the product quality Added value and meet environmental protection requirements. Taking Pingyang County, Wenzhou City as an example, there are nearly 100 pet food processing factories, large and small.

After cleaning, the pigskin or cowhide used to produce dog chews will first be dried naturally, and then dried to remove moisture. The traditional drying methods use firewood, coal or biomass steel furnaces, resulting in serious environmental pollution. There is still a big defect in the traditional drying method, that is, the drying is uneven, and the upper and lower layers and the left and right sides are different due to the different air volumes. It needs to be reversed frequently, and the labor cost is very high. It will also cause serious secondary pollution to the material. Traditional drying equipment pollutes the environment, and combustion boilers have been gradually banned by the government, so pet food processing plants have begun to seek new drying methods.

The pet food dryer needs to dry a variety of pet food of different sizes, and the drying time will vary, generally 2~4 days (48-96 hours), and 4~6 tons of wet material can be dried in a single drying. 1~2 tons. During the drying process, the hot air circulates inside the drying room, and there is no waste gas or waste discharged, which is environmentally friendly and guarantees the hygiene and safety of materials. 24-hour automatic operation, no need for special personnel on duty.

The pet food dryer needs to heat up quickly in the early stage, shape the material, and then need two hours of high-temperature sterilization and disinfection in the later stage. In the whole drying process, the uniformity of the drying room and the temperature difference between the front and back of the drying room are required to be high, and the temperature difference between the front and rear of the drying room cannot exceed 4 ℃.

The drying effect of the air energy heat pump is very good, the drying quality is much improved than that of burning coal, and the operating cost is basically the same as that of burning coal, but there is no need to worry about the inspection by the environmental protection department, and it also saves a lot of labor costs.
