The bamboo bed vibrating air cooler and the LB-1 air cooler are basically similar in operation. The freshly cooked materials are sent to the cool bed, and the materials are transported on the cooler conveyor belt for a distance within the distance. The material is forced to cool by the fan, and then the device automatically completes the process of falling and mixing. The difference is that the former's falling mechanism is unreliable, and often needs people to help the falling, which brings inconvenience to the user. Another type of drop mechanism is very reliable and easy to operate.
Cooling evenly, temperature adjustable, low power consumption. Since the fan of the mantle type cooler is usually installed at one end of the cool bed, the length of the cool bed is generally 7-8 meters, and the material near the end of the fan is naturally cooled faster, and the farther away from the fan, the slower the material is cooled. This makes it impossible to cool the material evenly. In addition, in order to ensure that the material farthest from the fan can also be cooled quickly, the power of the fan must be selected to be large enough, so the fan power of such a cooler is usually two. ) Generally, it is around a dozen kilowatts, so the power consumption is very large.
For the bamboo bed vibrating air cooler, although the cooling method of the material is almost the same as that of the LB-1 type cooler, the former is to transfer the material by the bamboo bed, and the bamboo bed is a bamboo string with a width of about 4 cm. Knotted, the distance between the two bamboo pieces should not be too wide, otherwise the material will leak, which makes the conveyor belt less permeable, and the arrangement of the fan of this type of machine is also in the length direction of the bed, so the material is cooled. It is relatively slow. In order to make the material cool quickly, it is also necessary to select a fan with a larger power to meet the requirements. This makes the power consumption of the force-sensitive tape of this type of equipment larger.
The conveyor belt used in the LB-1 air cooler is a stainless steel mesh, which has good air permeability, and the material is relatively easy to cool on the upper side. The fan of this equipment is arranged on both sides of the width of the cooling bed to make the fan and the material. The distance is very close, so the power required by the fan can be much smaller, and the power consumption of the whole device is greatly reduced, so the total power of the machine is only 3.78 kW.
In addition, for different seasons, different material temperature requirements can be met by adjusting the number of different fans. When the temperature of the cooled material is higher or when the ambient temperature is lower, the number of fans can be reduced. 4, can only open two), in addition to adjusting the thickness of the material by adjusting the height of the limit scraper mounted on the cool bed, in order to adjust the temperature of the material to be cooled.
As mentioned above, the bamboo bed vibrating and large-mixing mixer and the mantle-type cool-mixing machine have some drawbacks, and for the mantle-type cooler, it is basically removed from the Yang mix. It is done by hand. For different people, different work attitudes, the uniformity of the song and the mix is ​​difficult to be the same, so that the quality of the material mix is ​​unstable.
For the bamboo bed vibrating air cooler, although the falling and mixing songs should be completed automatically, in the actual working process, the falling hole is often blocked by the song, and the falling of the song is interrupted, so that the falling is unreliable. Unevenness, at this time, it is necessary to help people to drop the music, which is troublesome, and at the same time, the unevenness of the falling can also result in unevenness of the mixing.
